Alternative Turbo's to K14

As you've probably seen from the hundreds of other threads i've started, I now have an AAZ in the van.

However I've had a few problems, and been sold some duff parts to boot.

Long and short of it is that I now have the AAZ running, but the K14 Turbo is duff, no play in the shaft, but oil pouring down the exhaust.

I have what I believe is the JX ex.manifold, with a 4 stud flange.

I was using a K14 Turbo, I've attached a photo of the Part number plate on it.

Photo of the exhaust manifold flange..

Finally, one of the over all unit.  Excuse the actuator pipe, I only put that bit of fuel hose on so I didnt lose it.

I've been trying to source a replacement, but it seems this is quite a rare beastie, as such does anyone know of a suitable alternative I could use?

Thanks guys

I'll try futbus and see how much them adapter plates are...

Thanks

Im looking at getting the K14 rebuilt.

However my brother in law works for a well known jap car tuners, and has the facility to build exhausts and manifolds.  So, we are making a new manifold to suit an alternative turbo, and exhaust to suit once I can find a good replacement :)
