Put the gsr tranny on there it has shorter gears than the ls and will allow you to accelerate faster. As for the turbo kit, give us more info like budget, hp goals, type of driving the car is going to see, ect....
Once you give me that info I can help. If you don't know much about turbo charging a car you need to do a lot research before you make a decision.

i know alot about honda tunning n turbos well i want to at least give me 4 door a respectable name so like 250whp n how much ever that will cost im up for it

The GS-R tranny. Simply because it has shorter gears than the LS and will help with acceleration. And since you've already got it, might as well use it.

As for the turbo kit... there are tons of them to choose from. Drag makes a good kit. But check out turbokits.com for more ideas of pricing and the turbos that come with each kit.

but i thought it was said that it would be better to use the ls tranny cause of the longer gearing so therefore the turbo would be more effective

There's a huge debate on whether a longer geared tranny is better or not for a turbo application. But the fact is that the shorter geared tranny will always be better for acceleration no matter how you look at it. I'm sure if you search around the forum you'll find quite a few threads about it and be able to decide for yourself on which is better for you.

It is a long running myth in the Honda community that the ls tanny is better for boost.This is a quote from boosted hybrid aka Jeff Evans of Evans Tuning (web-site www.evans-tuning.com great info on the forum) and since this guy is way smarter than I'll ever be I’ll let him tell you why the ls tranny is no good for any performance driving.
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.

that answers it hands down
