Bugeye Sti heads.. JDM vs UK
Anyone know what the difference between uk and jdm heads are?
I'm not talking big port newer models but purely bugeye Sti. I know the jdm revs 1krpm higher but are the cams different? I actually thought the jdm was different but I rang a subaru breaker last week who told me there's no difference between the two. *He seemed pretty convinced and said only later big port heads are different. I've trawled the net but can't find any info. |
I thought the jdm has big port heads. Got me thinking now.

They have hotter cams.

Big port heads are blob eye on jdm. Bugeye are not big port. I just need to find out whether there's any difference between jdm and uk Sti heads regarding cams etc.

iirc the jdm bug sti cams are the same spec as the later version 9 uk cams,ill check.
|
The jdm bug cams have more duration/less lift than uk cams.
|
Think they should be big port too.

Right, just been pointed here http://forums.nasioc.com/forums/showthread.php?t=823167
According to Subaru part numbers all Uk/eu/jdm my01/my02 Sti cams are the same. Only my02 with different cams are spec c's. All parts on eu/uk/jdm heads have same part numbers except spec c. The cams changed in 03 along with big port as we know. Edited to add.. Eur and jdm heads have different part number though! |
