hey, i heard civic type R pistons were good for LSVTEC, i was wondering if anyone could back that statment or can give me more info on pistons for LSVTEC, integra type R? aftermarket? CTR? just need info on piston/ring combos?

allmtr

CR will be pretty high. i dont think pump gas. pr3 (jdm b16) should be awsome.

-Racer X-

CTR pistons would make it so i would have to use race fuel?? i dont get it

CRX_VTEC

the compression will be really really high thats why you will need high octane fuel. Or you can use a multi-layer head gasket. And retard the timing too...

-Racer X-

11:1 is high? dont ITR's run 11.5:1? and 91 octane is what is availible to me

allmtr

the CR will be like 12:1 and up. different pistons in different engines is a diff CR. which head you use should make it diff also.

allmtr

CTR is higher compression than ITR. have you seen that dome on top. woooooweee.

-Racer X-

ill be runnin a b16a head on a b18a block, with CTR cams, I/H/E, nitrous... i just need to know exactly what kind of pistons would be best for a all motor + nitrous application

b19coupe

For nitrous you should use forged pistons-J.E., SRP, etc.

how are you planing on run'n all motor and n2o? what do you plan on runing your compression at? 20:1 or something?

-Racer X-

i want a good all motor, but i want something that can handle no2 too....and why would i run 20 :1 compression?

ctr piston in a LS = 12.4-12.5 compression ratio. This is FINE on Pump gas, just make sure you get the car tune.

-Racer X-

whoa...actuall numbers thansk for the info...12.5:1 is good for all motor on 91 octane..just need the right timing and everything tuned like you said...thanks again

dude i heard ctr pistons will give u a 13:1 cr. but u better research more.

sparkz

I wouldnt do this as a daily driver in so cali. We only get 91 octane. Be prepared to change head gaskets often if you like to race on the streets.

-Racer X-

we only get 91 octane here too...

DOHCtorTHRUST

i know this guy thats running CTR pistons in his lsvtec on an integ chasis, one fast as car.... but he had to run on race ruel on the streets. i think itr will be better for you

digitalhav0c

20:1 HUM LOL WTF

-Racer X-

ya, im gonna be on a DA9 chasis (93 integra), hmmmm anyone know what ITR compressionw ill be?

Plan B

man, i get 93 octane on every corner, and I can drive 2 miles and get 110 octane in a can.

WE GOT 118 OCTANE HERE.....

So what are the preferred pistons for a daily driven LS/Vtec ?

dont the ctr's have to big of a dome????

Halo

ctr wont be too extreme if you use a thicker headgasket, also what head are you planning on running? B16 head will lower compression while GSR head will raise it
