MY build is as follows-
*B16a with ek9 pistons
*B16a2 head (skimmed 30 thou) with skunk2 stage 2 cams
*7.5lb flywheel
*high c/r cometic head gasket
*S80 lsd tranny
*CAI
*ITR exhaust mani
*full 2 1/4 exhaust
*OEM cat convertor
*C/R is at around 12.1.1

What t/b size would you guys recommend?
Would 70mm be too big?

 

Anyone??

I dont wana buy a 70mm if its going to big?

 

Thats the size i bought mine, im running 11:57:1, i belive 70mm is the size of a skunk 2 intake manifold opening. So all in all it should work just fine.

 

Thanks for the reply, ive bought a 70mm skunk 2 t/b and a skunk 2 intake mani. So ill have it RR when they come.

I got told the manifold had a 66mm opening? If it has ill just machine it to match the t/b.
