i have a GSR with a b16 tranny. many people is telling the that the tranny is not good with boost. should i trade it for a GSR tranny then boost it? or keep it short geared?

keep the B16 tranny.

second that, I have a b16 tranny on my turbo gsr and i love it.

ls/vtec with my stock b16 tranny.. Wouldn't have it any other way.

I have heard a lot of good things about B16 trans. with boost. I thought the same thing about switching GSR trans. so I researched and found a lot of people with B16's and they work really well. I have not personally experienced it yet, my car is still being put together.

i had a b16 tranny and i loved it. i wouldnt get anything else

i guess i should slap the folkS that tells me that long gear ratios are better for boost and that short gears like ITR and B16 are only for all motor

yee SERIOUS

longer gears will let you boost longer, but the short gears will keep you in your power band. which one is better? i'd say you'll want to stay in your power band. especially because of vtec

My GSR has a 7psi on a B16 tranny and I love it. 1st gear is always traction issues though.

Yea and i dont think u'll need really need to go over 140mph right?

this might give you a little insight on short/longer gears. i saved it cause i like how jeff evans broke it down:

Gear ratios are merely a way to trade torque for rpm. With a higher numerical gear ratio, you are putting more rpm at the wheel. With closer gear ratios, you are able to stay at a higher rpm in between shift points. Something like the LS transmissions are suited more towards the broad torque curve/low reving LS engine. It keeps you in the peak torque area in between shifts. The ITR/SI/GSR transmissions keep the rpm's built up in between shifts, to stay in the more peaky powerband.
Having said that, for the track the itr/si tranny is the best hands down. Most high whp turbo engines are operating between 5.5-9k, and having their shift points in between. In combination with a tall slick size (24.5"+), and the high shift point (8.5-9k), you are able to keep the engine operating within the optimum torque curve.

With the LS transmission, between shifts it would possibly drop you out of the optimal powerband and therefore make you slower. Gearing simply put allows you to stay in the powerband of your engine in between shifts.

The myth that you stay in gear longer with the LS transmission makes you faster is purely false. Think about that statement for a second. Acceleration is the measure of velocity over a unit time. Watching the rpms climb on the tach during a 3rd/4th gear pull, they would be climbing slower than with the si/itr tranny. Looking at the definition of acceleration as a measure of velocity over a unit time, the engine would be getting to the same velocity over a slower time lapse. This would yield slower acceleration, and simply put make you slower.

Having said that, the gsr transmission is probably the best balance of a street/strip transmission. The gearing is a little less aggressive as the itr/si transmissions, which will yield a little more traction. For all out acceleration si/itr tranny wins hands down. For a slower car, go with the LS transmission. </TD></TR></TABLE>

A friend of mine went 11.2 with a stock gsr just rods/pistons on 15psi with a usdm type r trans. i dont see any problems there
