As titled, im building a fully forged low comp bottom end (b18c4) and the plan is to just bolt my jdm itr cylinder head onto it.. (arp head studs/cometic gasket)
question is will this be ok with stock valve springs/retainers etc? estimated power will be between 300-400bhp..

i was guessing it would be ok as people are bolting turbos onto stock itr's and pushing around 300bhp..

thanks guys - dan

 

Yes, you will be fine. You can easily go to stock rev limit with it, probably a bit higher if you would like.

 

why super low compression? is there a lack of good fuel in your location?

 

should be fine, i know alot of people who have stock itr heads and make great power
