60-1 turbonetics, .48 exh too small?
 
i just picked up a used 60-1 Turbonetics turbo For $50 from a friend (needs a rebuild)

anyways the questions are, is a .48 hotside far too small? should be around .96 or so right? thats ideal? Im guessing it would have been on a sr20 for drifting

I know i could just buy a new bigger hotside housing, would i have to change the exhaust wheel to match?

would using a stock S5 hotside be ideal in terms of cost? can it be done? ive got both of them here and i don't want to take the S5 apart until i know it can be done

Id like to use the .48 it has a nice Large internal waste gate with an adjustable actuator but i dont really want to choke myself for power

Stock S5 T2 keg used mainly for circuit and touge runs

thanks guys!

what exhaust wheel does it have (measurements)? is it even a T4 turbine housing?

yes, a 48 is too small. when i initially fixtured my twin TO4s i had 48 housings... that'd be
one for each rotor.

the backpressure was so great i split both housings!

i would go w an 82 and a stage 5 wheel. it is v important to get the hotside right on a rotary.
