Anyways, so then I need to find an astron II rocker cover and a new inlet m...

I thought I heard someone say that the inlet manifold bolt pattern is different aswell? So with a lower compression I will have to tune my carby to suit? Also did you have an answer for my breather hose question? I have an astron II engine.

Does anyone know if the 2.6L pajero head will fit on the sigma engine? Also I think the seal at the front is different to the sigma it doesn't have the breather hose there. Does this mean I can't use it?

Sorry if this is a stupid question but does the GH sigma turbo manifold fit on the 2.6L engine?

I have a manual GJ Siggy and was going to buy an auto GJ for some parts, will the diff and tailshafts be exactly the same ?? Help if you can, thanks!

Ok Sweet Thanks Dude!

Let me know how it all goes. I will post pics of mine when its done. (If it ever gets done) Later.

Yeh it was the 2.6L engine. Its a GSR. Ok so basically remove the astron engine, take some measurements to see if it fits. How about the engine mounts, will that be a difficult task? And how do you go about doing that? Also, what are you doing for the radiator, the diff, and tailshaft? I would like ...
