ok well i have decided to go all motor on a budget. im getting a ls swap like very very soon. but it is coming with a hydro tranny. so im gonna trade the tranny and some other parts for a b16 long block. im gonna go ls/vtec. i was gonna use ctr pistons but i have been hearing mixxed opinions on them. should i use ctr pistons or the pr3s from the b16 longblock? it probly wont be my daily driver but i would still like to be able run pump gas. so thanks for any help.

 

Pr3 s 4 sure if you are gonna purchase new pistons then do the p30s

 

well i was gonna purchase new ctrs but i will just use the pr3s from the long block im getting

 

use the pr3's but if its not going to be your daily then build up the ls block with ctr pistons...im assuming you have at least 93 octane where you live right?

 

yeah we got 93 octane but i dont wanna have to worrie about blowind it up. or messing anything up. so ill just use the pr3s. that'll save me some cash too. i know there cant be any right on answer but what kinda hp numbers come outta a motor like the one im building? thanks

 

just a ls/vtec with pr3s and that is it? ohh and are there any other kind of oem pistons that are higher comp than pr3s but not as high as ctrs?

 

yes p30s

x2 they would be the perfect medium. it will have like a low 12 something :1 ratio

 

ohh ok ill look into some p30s would they be streetable. like could i run pump gas? lmk thanks

edit: damn ebay dont have but one used set umm are itr pistons the same as ctr? if not then are they useable? thanks for the help ppl

 

Absolutely. Just get it tuned.

 

ok i know they are useable but are they the same as ctr? is the compression gonna be to high? thanks

 

I THINK YOU SHOULD GO WIT THE CTR,S I HAD A SIMILAR SETUP LIKE THAT LS BLOCK CTRS LS RODS WIT ARP BOLTS I HAD A STOCK TYPE R HEAD WIT SKUNK 2 CAM GEARS WASNT DIALED IN AND MADE 198 WHP I LATA ON GOT SOME SKUNK STAGE 3 CAMS A KATMAN JHPUSA CHIPPED COMP WIT VAFC AND MADE 213 STILL 81 TRIM SO GO WIT THE CTR,S RETARD THE TIMING AND YOU COULD RUN 89 OR 93 YOU CAN EVEN ADD A LIL OCTANE BOOSTER IF YOU WANT

I think P30s would be right before the border between pump gas and race fuel.

ITRs and CTRs are COMPLETELY different. Not even close to the same.

If you're having trouble finding P30s new then just use your PR3s (its only like .3 less than P30) or if you want new PR3s get them from RSMachines

 

ill just use the pr3s with the longblock. thanks

 

p30's

 

p30's!! unless your build up is skilled and a skilled tuner like my setup we daily drive our's on pump gas.... right Chris???

 

i have a set of p30's on ls rods forsale... mint condition only 3,000 miles on them!

 

well my deal on the ls swap has fail through. but i found another one so im just gonna go ls boost for a while. then ill go ls/vtec boost. thanks for the help ppl.

 

wat motor is the p30?

its not a motor persay. They're refering to the pistons of a JDM B16A (SIRII) a.k.a. P30 pistons.

 

my vote is for the p30's. They have less of a domed piston which although it decreases overall compression, it allows for less disruption of airflow, which in my opinion is more essential in making good power. The p30s are also a bunch lighter, which make not make a world of difference, but i like it. They're both about 170 bucks new, i picked mine up a h motors but i'm sure others carry them also.

 

P30s and mill.
