Well you’ll be forced to use a T4 exhaust flange, so plan on that. As far as t70’s go, obviously its a 70mm inducer (compressor wheel). The back end is where you get to play around.
Tangential or Oncenter housings, O P or Q trim options, and A/R’s including .50, .58, .69, .70, .81, .84, .96, 1.00, etc.
Q trim is more, ball-bearing is more… I’d have to call for prices.
I kinda dissagree with this. I have a sbc i am eyeballing for my 81 corolla drag car and want to do twins. The manifolds will be easier to make, the power will be easier to make, the spool time will be more street friendly and easier to tune (no gigantic spike in power at higher, more scarey rpm).
hey, 1 bigger might be better than 2 smaller, but 2 bigger are better than 1 bigger!!!
