friend building a Ls V-tec with ctr pistons what rings should he run?

 

ctr

 

i think ur compression ratio is gonna be a bit too high with CTR pistons inside and ls/vtec pretty close to unstreetable, but i could be wrong. what does everyone else think?

 

with a gsr head he will be at 12.6:1 with a b16 head he will be at 12.3:1

so its a little high but streetable with good tuning.

 

your wrong he he

 

Its always streetabowl Thanks 4 the info. He is going to run b16 head. whats the comp.rate on that?

 

 

Thank U

But what about the valve clearence ?

 

im going to go with similar setup what exactly do you mean by good tunning?? hit me up on im if ur not too busy thanks.

 

He means do not let it see a lean mixture or detonation will result. The margin of error with 12.6:1 c/r is small.

 

Well man i have an Lsvtec in a Crx w GSr head ctr cams jdm 4-1 and the compression is not 12.6:1 dont know what peeps r saying?? about that also daily driver no probs... when i just did the block w stock header, head, cams etc i ran 13.2 @102.. I have since upgraded to skunk2 manifold, ctr cams, afc, LSD tranny and JDM 4-1 header. no dyno but halls ***.. no times yet. If u need ne help my Aim is ExospeedLsV... or check out our website at Exospeed.com, we build nething sell nething .. Let me know what u think i can help out w ne questions u need .. Good Luck

 

I think it actually works out to 12.3:1ish w/ CTR pistons in an LS/Vtec w/ GSR head. Still it's high enough that you need it tuned properly to avoid a visit from the detonation fairy.
