itr pistons

[Insanevtec99]

ican get fairly new itr pistons for $150.00 to put into my b16a2 . would it be worth my time and effort??

no, you will lose power

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]

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

 

[posol]

no.

putting itr pistons in a b16 will LOWER the compression.

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

 

[sohcslammer]

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

 

[posol]

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/compcalc/compcalc.php

 

[sohcslammer]

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? 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)

 

[posol]

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]

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

 

[WannabeSI]

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]

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