Hi there, just a bit of quick advice please. Would the STI9 crank fit in the P1/STI5 block without additional machining to the block?

I understand that there are Phase 1 & phase 2 engines but not sure where the change happened.

 

I think the change happened MY99, this is when the thrust bearing location changed.
API should be able to tell you.

 

Will fit straight in!

 

I have an Sti 5 and had an engine rebuild done by Zen Performance, they fitted an Sti 9 crank to my block, no problem. Give them a ring for advice.
Hope this helps.

 

straight forward fit, crank thrust bearing changed from centre to rear around 97-98...............done loads of these as it offers a very good crank without the aftermarket costs invovled...........

Great topic, my bigends have just gone on my V5 wagon which is the Phase 2 engine as in P1, so looking at exacty the same idea. Rebuilding mine with STi 8/9 crank. What pistons would someone recommend instead of putting the standard STi ones back, thinking they ay be the weak link somewhere down the line if I put them back in

Cheers

 

Would guess that Mark at Lateral can supply the sti9 crank cheap.

Smiles, speak to Mark, 0208420544 for advice on pistons or rods etc, or try Zen, RCMS, etc.

 

Many Thanks

I am also weighing up the cost to use a 2.5 instead of rebuilding my one

 

Again, speak to either of those mentioned

 

Will do, thanks for the replies

www.lateralperformnce.co.uk although it gives no more than contact details
