No, it won't be worth it. Better pistons, but not worth it.

Only thing thats worth it is aftermarket pistons, or CTR pistons.

says their dome.

they have a smaller CC than b16 pistons.

usdm itr: 3.64
usdm b16: 6.01

jdm itr: 5.96
jdm b16 : 6.93

jdm CTR: 8.63

usdm gsr: -0.60
jdm gsr: 2.52

usdm b17a gsr : 0.0

sohcslammer · 04-09-2004, 03:02 AM

right, but an overall higher c/r right? so in theory it would produce more power. Not alot, but some.

in a gsr motor -

usdm itr -10.8
jdm itr -11.3
b16 - i can't remember, 10.0 i think

pissedoffsol · 04-09-2004, 03:03 AM

no.

putting itr pistons in a b16 will LOWER the compression.

the pistons have a smaller dome, and thus, make less compression

sohcslammer · 04-09-2004, 03:05 AM

so what c/r do b16 pistons have in a gsr motor?

pissedoffsol · 04-09-2004, 03:11 AM

jdm: 11.6
usdm: 11.4

b16 pistons in a GSR block, head, and headgasket and piston to deck height will yeld those results.

have a look here: http://www.c-speedracing.com/howto/c...c/compcalc.php

sohcslammer · 04-09-2004, 03:13 AM

Well, what the fuck. Those are alot cheaper than the itrs I had in my car. and mine were only 10.8:1. Wish I had known that.... Are you noobs paying atention? :P j/k

Dude, that calculator is sick. good hookup. so ctr pistons in a b20/vtec with a b16 head, stock deck height, stock head gasket is 13.0:1 c/r ...... wow.... B)

pissedoffsol · 04-09-2004, 03:21 AM

yes, but they dont fit the rods. lol

b16a/ls/b20 pistsons and rods will interchage
gsr/itr/ctr pistons and rods will interchange

sohcslammer · 04-09-2004, 03:27 AM

But doesn't wild Bill have ctr pistons on LS rods?????

WannabeSI · 04-09-2004, 03:53 AM

they will work on the b16 or ls rods you just have to have them machined down a bit so they fit because the rods are a little thicker on the b16 and ls. a machine shop can get them to work

sohcslammer · 04-09-2004, 04:02 AM

how do you like the b20/vtec? lots of torque?
