Greetings from across the pond (Chicago, USA)! I have recently bought what is apparently a V7 UK STI engine, and have come into conflicting reports in regards to the heads being the same as JDM. Do any of you guys know the answer to this? It would be greatly appreciated.

Thanks,
Cody

 

help the new guy!

...please?

 

The jdm are bigger than uk heads, Had my 01 V7 jdm rebuilt 3 months ago , to 2.5 my mate who did the engine work >> and everything else Did think mine were UK heads because there so much alike , hope this helps , cheers Alan.

 

thanks for the help... now the bigger question is, how much does that affect performance in these engines?

thanks again,
cody

 

I dont know , But some-one will come along that does,
