The build up has started. Recepy:
-Evo3 head. It will be taken as far as it needs. Currently using Evo2 with bigger valves etc. -New intake manifold. -Performance cam. This will be something new and maybe it will need multiple takes to get it right. -Twin turbo setup: I'm going to stick with the current one (gt23v-AMG) and add another vnt, gt37v to it. Luckily I have a big trunk... Things will be electronically controlled. This is the hardest part. I hope I get it right. For you that haven't ever seen a gt37v, this one is HUGE. Even HX50 is small compared to it. -Additional A/W cooler. -Fueling mods to get power up to 6000rpm, but I think I'll eventually need an additional pump to keep that bigger turbo happy. That's not going to happen with this build as this is too tricky as it is. -New rods, lighter/modified pistons, knife edge crank. -Lightweight SMF + twin carbon disc clutch. This is going to be the worst part for driveability. -New gearbox with some exotic stuff in it: longer 1st, LSD from WRC Focus, dog engagement. -330mm brakes in front + 8 pot calibers. -Original rear discs + 4 pot calibers. -Anti-lag system. -Weight shaving up to 200kg, but that big turbo isn't going to make it easy (as it weights about 40kg). -New angel-eye lights with custom look in the nose section. 6xHID. I think I have almost every part ready, but it's not going to be a walk in the park...

Original TDI with custom made 12mm rotor head (11mm originally) and race520 nozzles. With the build I'm going to try to find bigger nozzles with more holes on them (now 5).

Nice motor, love the quarter mile time :D that would put some of my friends cars to shame lol. You seem like the man to talk to when it comes to bhp out of a 2.5.

Intake will be looking something like this (left one). Long runners are going to be taken from D24 Volvo (6syl).
Here's some pics of the home made collector. Small end. Also decided to make a girdle to beef up the bottom end. |

It's always nice to see two dots above "a" or "o" as that means then you aren't far away from home. BTW, we are building almost similar T3 too. It has VW's 2.4L inline six IDI engine with two vnts and uses Porsche gearbox. +350hp hopefully... Edited by shadowmaker - 19 Jan 09 at 22:41 |

Here's my new dual disc clutch. I'm a little afraid how it is going to behave...
Here's a donor for my dual plenum intake. Runners are 50cm long. |

That is my goal with dual plenum intake. With diesels (unlike gassers) too much fuel without cooling air will destroy your engine. |

It must be the way the Vodka is filtered, that makes you finish go that "little bit further"
