Spool up difference was about 200 rpm on a 2 liter with a 60-1 between those housings, with a 2.3 it should be even less. If you are maxing out the turbo, I've seen people pick up 20-30 whp with the housing change. If you're ***** footin around with 22 psi I doubt you'll see much of an increase.

Either way, I always lean toward the larger housings on strokers. For the same boost pressure you have roughly 15% more airflow and therefore exhaust product to pass through the turbine side. IMO, larger housings are a better fit for larger motors.

I'm not sure I understand your post. I doubt the 82 would add enough power at that low boost level to offset the increase in lag, but each person has his own tolerance level.

I have the .82 on mine. Same setup as you.

I never had the .63 but i can tell you from what i've been told the .82 is worth about another 30-40 whp and spool time on a 2.3 is still fast.

I get full boost on my car at about 4500-4800 depending on gear and speed......

And it's a 2.3/gt35r.82 and it f_cking rips........

id get the .63 if you're looking for a lil better low-end response. the .82 is a highway turbo.

How much do you gain with a .82 over a .63 on like a GT3076 or GT35R ball bearing Turbo?


(I guess its all about what you want from the car - I have had experiance with T3-T4 Turbo's on 2L 4Cly 16V Engines and even in drag applications unless you gona rev to over 8000rpm the extra HP is not usually worth the Jakle & Hyde power delivery and loss in spool-up especially not if you running over 23psi boost...

Going to a smaller housing with a smoother delivery setup usually gains me ET's in street cars - Drag cars can get by with Big Turbo's, High Rpm launches and short gear ratios.)

.82

If your into drag racing, .82. If you are into road courses, you will want the additional mid-range power, go with the .63.
