that is the question. going 84mm with 12:5 compression should i sleeve the block? or can i go without?! for a B18c (gsr) block.

thanks

I would think about rods first, but sleeving is a good idea in most cases.

Dru - Who looks in the mirror every day and says "Build a better bottom end."

 

You would be starting with a B20 correct.... Don't try to bore the LS up that far (i don't think you are but just makin sure) With a B20 you can bore .50mm over and be totally safe... My friend's CRVTEC is bored .50mm over on stock sleeves, JE 12.5:1 slugs, and STOCK rods w/ ARP rod bolts..... In his full interior daily driven EK his best is a 12.62@107... On top of the bottom end it's just a Portflow GSR head with CTR intake cam, SK2 manifold and sprockets, RC 310's, ITR ECU and VAFC... You should be fine... Good Luck

 

sorry to i forgot to mention. im doing this on a B18c block.

 

I'd say sleeve it

 

Yea for the B18C sleeve it most definately... There is no way to go to 84mm without doing so... This is similar to my setup except mine is to 85mm with 13.0:1 slugs... Check out Golden Eagle.... B18C is the shiet http://www.goldeneaglemfg.com/sleeves.htm

can you list ur set up. thanks.

 

B18C1 Golden Eagle sleeved to 85mm, JE 13.0:1 slugs on ITR rods, Portflow PR3 head, ITR intake manifold and throttle body, JUN 3 cams and valvetrain, SK2 sprockets, RC 370cc injectors, Cometic .029" head gasket, ITR tranny, Quaife LSD, ACT HD PP w/ 6 puck disk, Toda t-belt (for looks), chipped P28 and Hondata 4 in an EG....

 

WOW ! is that daily driven? thats a pretty mean set up ! what octane are you using? what does your compression come out to after that head gasket? wherd ya get your toda belt? oh and one more quesion ( SORRY) how high do you bring revs up to? what rpm do you shift at?

 

It's not done yet.... I'll let you know when we finish... hehe... My friend's old CRVTEC with JUN3's reved to 8800 and started to have a little drop off after that... It was the same motor as my friend's now that has a CTR intake cam... Unfortunately the JUN intake cam shattered and blew up the motor which was most likely because we were running portflow inners... Which are too stiff and aren't linear progressive... That motor felt a lot stronger than my friend's CRVTEC EK now that runs 12.60's with the CTR intake cam.... Too bad that first motor wouldn't have lasted longer, I bet that thing could have pulled low 12's in a full interior EK... Oh well I'll keep ya posted.. Peace... PS my new motor will be run on 92... Just gotta get the tuning right...

How do you guys run stock rods w/ aftermarket pistons? Do you modify the rods?

I know importbuilders have pistons that can be used with stock pins and rods . Are these it?
