my build (as of now)

stock b18b block
b16 (pr3) head
portflow valvesprings/retainers
crower stage 1's
hks cam gears
aem fuel rail/fpr
skunk2 intake manifold
i/h/e
ls tranny
p28 (uberdata)

well so far so good... im putting out 169 whp and 127 tq @ 7400 rpm... but i dont want to stop there...

just yesterday i ordered some ctr pistons and rings.
im thinking of going with ACL rod bearings and some ARP rod bolts.

will these pistons make it possible for me to take my rev up to the limit of the cams which is (8200) without worry?

will i still be able to upgrade to a higher lift cam w/ the ctr pistons? ive heard talk of not being able to, due to a higher chance of spinning a bearing.

he reason for the question is because im looking into getting some stage 3 crower cams, or mayb even some itr cams. which would be the more gain worthy cam to go with?

thanks in advance for the help.

use b16 pistons so you'll be in the 11's compression so you can run the bigger cam. you dont have to worry about the valve hitting the piston

Why would going from a stock piston to another stock piston affect your "rpm limit?"

Why would you downgrade from a "stage 1 cam" to a type r?

well i know that the ctr pistons will raise my compression so why wouldnt i want to go from lower compression stock pistons to higher compression stock pistons...

and as for going with the itr cams... i dont exactly know the lift on the itrs, but from what ive heard the stage 1's have just a little more lift than the stock gsr cams... feel free to correct me if im wrong...

 

go with some P30 or PR3 pistons so you can run larger cams in the future, your compression ratio will be a mid to high 11.something:1 so you can tune it easier on pump gas

IMO get the P30 or PR3 pistons if you want to use OEM pistons, CTR's have too much dome

 

P30's.

well thats a little too late unless someone wants to trade me my ctr's with rings for some p30's....

 

i have pr3's in my lsvtec... need cams though
