Yeah too big, 68-70mm is plenty.
but the price is a killer deal.... cant find the 70mmfor under a 100 bucks...
ok, so.
you will lose HP and TQ with it, so why waste the $100 on something that is not going to benefit any...
Its prob 100 bucks cuz theyve been sitting on it for a few years and just want to get their cost back.. you can buy it and sit on it too if u want.
a 90mm TB will NOT fit on a stock intake manifold, you'll have to have a custom manifold made ($1000+) to fit it, and have it flow properly.
I made the mistake of buying a 76mm TB. It BARELY fits on my ported out H manifold. It made a difference in power (about 5whp over a 70) but anything bigger would just be too much.
Plus cheap throttle bodies stick open quite often due to lack of coolant flowing through an aluminum housing with a steel butterfly.
ok.. thanks for the feedback guys.... i know that the stock T/B's wont flow what i need, so ill look for a 68/70...
uh, you'd be very surprised. I know plenty of guys making 400-450WHP on stock b series TB's/intake manifolds, and a couple guys making 550+ on stock h22 intake manifold/TB.
On boosted cars though, of course.
