T3-1.8T Conversion Thread
Hi just starting my 1.8t conversion in a vw T3
did the conversion a year ago with a 50 degree engine
how ever it all fitted perfect but the gearbox could not handle the power
from the 230bhp engine.
it was ok for local driving even at traffic lights line up.
but motorways it was a bit loud due to the gearbox gearing.
this time i am doing the conversion at 15 degree with the help of
tims adaptor plate which will fit to the audi gearbox flipped upside down.
before i ran a stand alone ecu from qpeng.
im in two minds as to which ecu to use at to moment.
thats the last job on my mind.
 
Heres a few pictures as the project goes on, this pic is when i had the 2.1 petrol engine
After i took the 2.1 out i started cleaning the engine bay by sandblasting it and then sprayed it with rust remedy and then top coated.
Went out and bought a Audi a4 1.8t sport with 105,000 on the clock, stripped it down and took the engine out first thing was to get rid of the things that i didnt need like the power steering and a.c as iv alredy got electronic power steering. Heres the pics of the pullys modified to run the external water pump.
After this i took the original engine support bar out from the T3 and cut the mountings off and cleaned the bar up, made the extensions for the support bar and made some mountings to support the engine.
Next step was to cut 15mil off the gearbox bell housing as the 15mil adapter plate is going on to flip the gearbox upside down. I did this by making my own jig and then using a router carefully cut 2mil at a time which was time taking but it cut with ease.
Before cutting i had to drill the dowl holes deeper as not to lose them.
 
Now im waiting for tim to get the adapter plate, gearbox mounting and cv joints so i can carry on mocking the height as where it will fit and then i can work out how high the engine will sit, will keep you informed as the project goes on and notify me with any ideas or tips.

Can't see your pics. If they have T2 5 in the title, swear filter changes it to T3, so you will need to rename them.

and I plan on being first, but with the least amount of engineering prowess..

FFS he's even made a jig to rout the gearbox,  that gets a win in my book from the start, my gearbox is now 15mm shorter but with no need for a jig..  

and he's thought about "dowl holes"..  fuck....

better crack on, I've got a junior hacksaw here with some fresh blades, it'll be fired up by morning.

seriously chap, only kidding about being first, good to see someone else playing with the 20vt - it's a great engine.

Can I ask you about the external water pump and modified pulleys etc.. on the pic above?

On the earlier 20vt the waterpump is on the
Outside .you need to cut the alternator bracket
In half so you can mount the alt back on
You can then get a vr pump pulley and use that
As the waterpump pulley and your done.
Alternative is to use mk 4 pulley take waterpump
Of and press the front pump about 2 mil in so
It lines up with the crank pulley . Hope that helps

Now I am all intreagued on a 50° fitting - does it fit under the lid OK? Also, what mounts did you use?

the 50 degree fitting will not sit under the lid you have to lift it by 6-7 inches.
the mounts have to be made up but the bars are the standard diesel ones
also you need to re make the sump.like a diesel sump.
turbo oil return has to be moved.
diesel belhousing g60 flywheel and vr6 clutch
if you are interested i do have all the bits to do the conversion again.
except for the flywheel and clutch

7 inches?

That seems like an awful lot, also taking the need to change sump, turbo oil return etc etc into account.

I keep coming back to the same example, but http://www.gmwerks.com/Vanagon.html" rel="nofollow - These guys do it at 15 degrees and raise the deck lid by an inch. Also means no messing about with sumps and oil feed returns.

Is there a reason why 50 degrees is better?

Thanks, that's a shame, as mine is a camper, I cannot raise the engine lid.

Still, that takes away the temptation - I just need to be happy with the agg conversion in it

Best of luck with yours, - I think it will be brilliant!

I am about to start fitting an AFN tdi upright and hope to get it to fit under the std boot floor as the conversion will be into a camper. Time will tell if a 15 deg engine install will fit.

these guys use the standard gearbox which i know will not last if you are running 200+bhp.unless you drive like an granny! I like to actually drive mineBig smile.
the golf or audi a3 sumps are flat at the bottom.
but the audi and passat 1.8t sump has a big notch in it to go over the cross member this is where i am going to fit my mounting bar so it does not sit below the sump.

hello Tim
regarding the 15 degree on afn engine; should fit under the lid
may be because the inlet and exhaust manifolds sit on the left of the engine
as posing to petrol where the inlet manifold sit on the opposite side and closer to the lid at 15 degree.

as you can see im trying to convert my t3 but i have a couple of questions if any one can help.
first of all is that im trying to line my gearbox (passat flipped).the gearbox mounting sits of set on the
2.1 t3 do i need to mount the passat gearbox the same way.
the other problem is the driveshafts do i need to put a spacer in one side as the gearbox is ofset,
or do i move the box to central and try to see if the shafts fit equal.
i have measured the shafts and both are the same length.
i know some 4 speed have different length shafts.
the 5 speed t3 box is wider than the passat.
if i centre the box might need to space both shafts equal.
like to come up with all advices then put them in a basket to come up with a final.

Martyn (Bus boy on here) used 2 equal size adaptors on his Passat gear box which he mounted in a central position. He made his own nose cone mount to suit (so the choice of fitting holes was not relevant as he did not use a std mount here) and he also fitted his 5 cylinder Audi motor where it needed to go to keep the drive flanges on the gear box central to the std 5 speed drive shafts.

I hope this helps.

Tim.

I'm keeping everything as central as I can.  engine (20VT) and box should be midline, gearbox mount isn't difficult to fab up, as are mounting points on the crossmember.

Got some info on driveshafts as well but not confirmed/tested yet but really want to keep with the stock T3 ones, with different inners.

thanks for the info.
what i have come up with is that,
t3 2.1 gearbox from flange to flange is 286mm
audi gearbox 270mm
that gives me 16mm difference
so if i make 2 spacers at 8mm each put one on each end,then  line the gearbox
central.i will know the thickness of the spacers once i have got the inner cv.
as far as i know the cv should be the same thickness as the stock  ones.
 dont know why i like to keep both shafts the same size not put spacer in one side or
use two different shaft sizes.
only time will tell!

another thing to take into account is that when you lower a van the distance between the flanges is shortened over a standard van. even derv and petrol gearbox flanges are in different positions but the drive shafts are the same length.so you have to take the suspension travel into account as well as gearbox position.


Posted By: Sid1800
Date Posted: 14 Oct 12 at 17:07
as lowering vehicle mine is standard,
i have measured my driveshaft heights before stripping the van.
so when i fit my gearbox in will measure again and try to fit as close to original position plus it depends on the height of the engine,want to raise engine lid by 2 inches the max,if it comes to it.
when lowering vehicle you dont change the driveshaft so if you sit the gearbox lower it should not make a difference.
if you hold the driveshaft at horizontal and lift it,it gives you the same distance as to lowering it.

here we have pictures of my spacers which i got a 108 driveshaft gave it to engineers and got them to cut two 8mm spacers for me.
as i was mocking the gear box to the engine notice the oil filter was fouling the gearbox.
after measuring up it was only fouling by one of the bolt holes,
which i can grind the corner of and the filter will fit.
if it was a diesel the oil filter is well bigger and a lot more problem if doing the 15 degree fitting.

finally got the adaptor plate and mount from tim.
started to mock the gearbox to the right height noticed that i cant go to high
due to the drive shafts hitting the top of wishbone.
here is some of the pictures of the build.
next was to mock where the engine will sit first made the engine mounts then fitted the
engine. it sits 2 inches lower than the deck lid.could do with it sitting little higher for
ground clearance,at the moment it is sitting 5 inches of the ground.
had to lower the gearbox mount by 12mm to get the engine to sit level.
next step is to fit the drive shafts but dont know which way to go round this yet,
if any body can help all is appreciated.

The petrol engine bar did not clear the Passat sump when put in line with the factory Passat rubber mounts. I guess from looking at your photos that your sump allowed space for the bar to pass behind the main pan of the sump. Are your alloy mounts from a Passat or another VW Audi car?

Looking good by the way.

I'll let you know what I do to fit my drive shafts next week.

hi tim
the engine bar does not clear the sump if you line it up from mount to mount.
the 2 tubes that fit to the mounts are ofset to the mount bar this gives you access to the nut 
that goes underneath so you can get a socket to tighten it up.
the mounts are the standard ones from the audi a4.
went into garage today and did all the water pipes and fuel lines
just need to work out where best place to fit intercooler.
then the exhaust system.

Have you looked at my intercooler scoop design posted on one of my build threads where the intercooler sits on top of the gearbox with an air scoop running down to the gearbox cross member. A low cost install that allows the use of std passat cooler.

looked at your intercooler nice job.
still looking where to fit my intercooler,reason being is that on the diesel the intake and the turbo is on the same side where as the petrol the intake is on the opposite. dont know if longer pipes will make difference to the time it takes to boost.might still try fitting it on the side of gearbox or just above.
now i have got the van on to the floor it is sitting 5 inches from floor.
as to oil filter with the adaptor plate in cant fit oil filter on.
i might try oil filter housing from transverse engine if it clears the engine mount if not need to buy oil filter relocation kit,then i can put oil filter any where in engine bay.

sorry for the delay but been busy here is a video of my 20vt caravelle for the first time start up.

just a few issues to sort out,first of all is the ecu is not sending a signal to switch the fuel pump relay on.
maybe because the immobilizer taken out of ecu has cut the supply to the relay but does start with the relay bypassed.the main issue is that the rev counter does not work,i need this to work because i am running electric power steering which needs a signal to work.if any body knows how or if any body can make me a tacho box,from the ecu i got a negative rev wire but does not work with the t3 rev counter.
other than that waiting for tim for the gear linkage to go for a test drive.
by the way thanks to tim for all the parts supplied and for all the information he has helped me on.
if any body doing diesel or petrol conversion tim is your man for all your conversion parts.

Hi Sid,
 
Its nice to see you on here at last.
 
I am keen to see how the 1.8t engine and box going into your van and the TDI conversion you are doing for Chris goes?
 
I am thinking of taking out the SVX conversion you helped me with and going for one of these.
 
Are you doing both of the conversions at the same time?
 
You should stick a few pics of the TDI conversion up when your able in the Diesel upgrade forum.
 
Cheers
Al

Hello al
I will get some pictures up shortly for the diesel conversion.
I am doing both vehicles at the same time just waiting on some
Parts at the moment. It looks like if you already have diesel the
Conversion is much easier if going to tdi petrol takes some fabrication
Parts to be made. But I have made it fit under the hood which is the main
Objective . Any idea on your svx engine what went wrong with it, is it worth saving.

why dont you flash the ecu to see what code comes up it should come up with coil pack problems.on mine
still having problems with rev counter got it to work with taking signal from ignition amplifier,but not accurate as i rev the powersteering kicks on but on idle no powersteering.
my vehicle revs faster than the needle moves,at the moment dont know what to do.
there must be someone out there who can give me some advice on what to do.

at last my t3/20vt is up and running.
got the rev counter and powersteering up and running.
so far have drove it 100 miles local driving and had no issues at the moment,
at 50 mph the revs were sat at 2000rpm and cruising along.
will get some pictures up soon of the rest of the conversion and it driving.
also waiting on ecu for chris van so i can test drive the 50 degree diesel install which i carried out aswell.

Congratulations mate!
 
Thats some going using the prototype parts.  Hopefully this solution will ensure our wagens have a modern alternative drivetrain.
 
I am really keen to see how Chris's Tdi conversion turns out. 
 
Any thoughts of performance chip upgrades at this point?
 
How does the 150bhp feel verses the 112bhp from the 2.1?


Posted By: Sid1800
Date Posted: 02 Jan 13 at 21:56
Hello
Alam happy new year.
You saying the difference, well the 2.1 on original
Box was good reving but the 20vt is more refined as to
How you drive it. The turbo is more like a supercharger
Long in gears 2nd gear easy 45. As for upgrade bigger turbo,
Injectors,and a remap should be easy 200bhp,
As you know I have had 230bhp in same vehicle
And I do drive it!

Hi there, great conversion youve done there
 
What gearbox are you using for this as you say its an Audi and all you did was turn it upside down, no internal mods at all???
 
Awesome stuff there Smile

Sid did the Diesel conversion is done too... my mate Chris should soon be picking up his camper with VW Passat TDi engine and gearbox (all from the same donar Passat) from Sid this or next week.
 
Sid has promised a test drive in his Turbo Caravelle with Audi engine and Box back to back with the Diesel conversion.
 
Lets see how they compare.  I'm hoping tag along and get a test drive myself.  I'll do a video and post them upf for everyone to have a looksee.  :)

Should make for a couple of interesting test drives.
Up to a few months ago I was all set on dropping an AFN in with a flipped box, however leaving any fuel savings out of the equation for the diesel I am quite keen on the 1.8t as an alternative so will be reading your comparison with interest.

hi im looking to do the same conversion with a upright diesel so every thing from an audi or passat will fit
need to do it with the entire engine sitting under the hood which should not be a problem.
the only issue is that i dont have any t3 left to do the conversion in so if any body out there whants it
installing give me a shout.ill be more than happy to do it.or for that matter even 1.8t.
 
does anybody know of someone who can do the wiring loom for the 1.9pd engine that will be the diesel
conversion to go for.

hi nothing is impossible to do the upright conversion,if i can do the 1.8t upright whats so hard about the
diesel upright.using the same engine mounting support bar for the petrol and diesel is the same.
hitting 88 miles per hour dont know what you mean i have had the van at 120 mph with a s3 engine on standard box in the same van.

Cracking job mate ive just started my 20vt build which direction did you go for the gearbox flip adapter plate or machine off and reweld? 



Posted By: Sid1800
Date Posted: 22 Feb 13 at 17:40
hi spuds
sorry just been a busy person from work and home.
any way the gearbox was cut on the face by 15mm all round due to the adaptor plate being 15mm thick.the direction is 180degree flip for the gearbox,no welding involved atall you can buy the adaptor plate from Tim under the user name vw nerd.he supplied me with the parts and i did the build.
 by the way your not to far from me (bradford)if you want to have a look at mine by all means if you make it during this week i can also show you a t3 with a 3.3 subaru that i did a while back.customer collecting it next week end.

Hi Sid,
 
what exhaust set up are you using for the 1.8T?  Is it a custom job?
 
I'm 90% certain the 1.8T is the route I'll be taking, just trying to piece together what parts I'll need, and the overall cost.
 
Thanks,
 
Ben.

Any more info on how you did this..


How did you level the box and hold it in place.?
Cheers

very interesting thread indeed...

i happen to have a '97 20vt aeb engined passat on my drive - i'm trying to decide whether to get rid of it or keep it to convert my bus...

any cons to this conversion or only pros?
and does anyone have a ballpark cost of parts required to go from 2.1 petrol to 20vt?

cheers.

Once you stand the gearbox up it will stand on its own,
It will level it self. The flat piece of board was 15mm thick the same amount
Of material I had to remove.

The main parts you need are
Gearbox mount
Adaptor plate
Driveshaft cv joints
Gear linkage
Engine mounting bar
Wiring loom and Ecu
Pipe works can be adapted
Have a word with Tim Shettle
He can supply all the parts needed for the conversion.
You just need to get some one to fit and adapt it all

Ok Cool.
I'm on the verge of doing this.

So you cut out a hole in the wooden 'table top' in the exact shape of the outer edge of the bellhousing,
Then placed the gearbox into the wooden template. Keeping it flush.
Then passed over 2mm at a time with the router. until you had 15mm cut off of it.?

Am I right.?

Thanks.
Dan.


Posted By: Sid1800
Date Posted: 06 Aug 13 at 18:14
That's right
Put the gearbox bell housing face down
Then draw around it and cut it out.
Then put the gearbox the other way round and
Make some legs for it, the legs might be slight
Difference in height but not matter as long as the
Board you cut sits level with the bell housing face.
You can have a board on either end of box and
Sandwich the gearbox in then make the legs for it
But it's how you feel comfortable with,
By the way don't forget to drill the dowel holes first

Hope that helps, any problem just bell me. You can
Cut more than 2mm but it depends on your router
Make sure you wear goggles.
Once done get a flat piece of wood with sand paper
And smooth the top.

Have u sorted your tachometer issue? On the pug motor with eps I simply converted my alternator to have a w signal, was very easy just took the rear cover of alt and solder a wire (w connection) to any of the outer 3 windings and job was done, then fine tuned tach with the little potentiometer screw in the back of it till it read correct engine speed at 70mph was a bit of trial and error but got there eventually

Hi I did the same with alternator w wire for the
Power steering.
For the rev counter I took a feed from each of
The 4 coils with a couple of diodes and the rev
Counter working.

here we go again I have just made a adaptor plate to fit the 20vt onto a standard t3 box.
it works a treat no gear linkage conversion or flip gearbox,driveshaft adaptors and on top of that adaptor
for gearbox.
ive made one adaptor and you can keep the original gearbox.
all you have to do is make engine mounts to fit the original engine cross bar,
ill post some pictures of adaptor plate and what you need to fit it.
the engine cover needs to be raised by 1 to 1 and inch depends on how you want the engine to sit.

have you also built a custom tray to go underneath to catch the debris when the standard gearbox gives up the ghost? Wink

My GTI conversion with standard gearbox, and diesel flywheel is dreadful even with a black diamond clutch, and thats only an alleged 115BHP. 

which box/flywheel combination you going with?

you cant beat the standard box especially the 5 speed.
been running it for 12 years no problem.
you used the diesel flywheel which is shiit
to small for the job.
early agu engine did a solid flywheel conversion which for the whole kit,
flywheel,clutch,pressureplate is only 155 to buy which is ideal for the money,
even a g60 flywheel alone will cost you 260 new.
I got 180bhp and it is fine.

yes and I also have the ABD 4 speed box, so double shit!

To be fair I knew it would be from the start, but thought I would get it on the road and sort it later.... still haven't got around to it yet!

Food for thought there - There is no real cheap answer to this from what I can tell (unless you already have the right 5 speed box) as the flipped box conversion is fairly expensive, but so are 5 speed boxes, and a decent rebuild as most of these boxes now are at leasT3+ years old. Having said that, i'm hoping to get a new car in the next couple of months, which means I can take my Audi A4 1.8T to bits, so i'm leaning towards the flipped box at the moment.

the flipped box is ok but I found out that the gears are to long,
you can go one end of street to the other just in second.
motor ways fine on flat and down,
but when it came to hills it would slow down to 60 then you had to drop gears and re built the momentum.which I don't like,
unless you use diesel gearbox shorter gears but don't know not tried it.
this is why I went back to 5 speed original.
I did run 230bhp on standard box and had no issue,
to many parts involved in the flipped gearbox,
don't get me wrong it is good coversion but for diesels.
you can fit the audi or Passat tdi in to t3 as it is with the adaptor plate I made with out the hassle of fitting it at 50degree,
which there again you need more parts which are getting hard to get hold off.
the main thing you need is a diesel bellhousing that's it.

depends on what you got first petrol or diesel,
not really worked out price as for a drive in and drive out service,
mechanical side is not a problem its when it comes to electrical side but working on to resolving it.
manage to get mine running after a lot of ecu problems.
but it was the donner car that had the ecu issues there from start which the last owner not told me about.

Interesting set up Sid and as you say, a lot less hassle than a flipped box if not wanting diesel.

Is this 20vt-t3 adapter plate/kit something you are going to be making available in the future, if so I would be interested.
