Hey I know that this topic has been beaten to death on h-t but I am reading mixed messages. I don't want to go out an buy a tranny and find out that I am not going to get what I want out of it!!!!!!!

thanks for all your guys input!!!

 

i run a b16 with an ls 5th, i am not turbo but i am nitrous and run about the same with the local turbo civics. That tranny works well for me.

 

I run the B16 as well, but I have the stock 5th and it sucks on the highway.

 

GSR, short enough but not too short for turbo
Strong too

 

gsr. i got one and it rocks!!

the mods hate, they took away 2% from me.

 

Go with the straight B16 trans and a quaife. I picked up about .4 in my turbo car by switching from the LS to a B16 trans, despite having to shift to 5th w/ the b16 because of my small tires and lower rev limiter, hopefully I'll have that fixed next year.

 

I've always been a fan of the short gearing weather it be for turbo, nitous, or NA. I plan on running a B16 tranny down the road but the LS will work for now in my LS/vtec Turbo.

 

I got a LS/Vtec turbo and I'm running the LS tranny (S80)... I like it a lot...

 

I have the LS on my LS/Vtec Turbo.. It's not really great for the quarter mile however cruising around and highway is lovely.. I between 3rd and 4th there is room to chill. The Type R tranny gears are way to close for me, you have to change way to quick.

 

thanks for the input guys

BUMP!!!!!!!!!

lots of good input thanks!

 

I run a hybrid gsr/si tranny. gsr 3rd and 5th rest Si, with a quaife on my ls/vtec.

 

1st and 2nd on GSRs and LSs are the same. according to my factory brochure. just to save people time and money.

The reason you like it a lot is because you probably havn't tried out a GSR or ITR trans yet, your car would pull a lot harder with either.

But his LS will keep him in boost longer . . .

 

I thought the ls tranny being in boost longer is a myth!!!!!!!

 

Power is made at points along the rpm band, not a designated time in boost. If you shift from 2nd to 3rd and drop to 5400 and your peak is 7800 thats not going to help you at all. Sure youll be in boost longer but you wont be anyhwere near your peak power points. generally speaking, Boosted Honda motors (VTEC in particular) peak very high so your going to want to choose a tranny that is going to keep the revs in the areas where your making power.

I'll have to disagree.

On the upshift, gearing should allow engine speed to drop near <u>peak Torque</u> after you shift at <u>peak Hp</u>. If you can do that while maintaining traction ..the car scoots . Thats just the basics of selecting gears for racing (which has been around forever).

Some of the advance stuff race teams would deal with would be for example unproportional gear scaling on the upper gears (making the gears slightly shorter) since the car is up to speed.. has a lot of momentum and doesn't need a lot of torque. Does not apply to all cars since every torque curve is different. But slightly shorter gearing in that area could take the engine too peak Hp faster.. making the car quicker

 

Will having the LS tranny effect the car in the quater mile very much would I be better to get a GSR tranny?

 

I've had experience with both, Gsr tranny in my last setup and Ls in my current, all i can say is Ls 3rd and 4th gears are dogs, I miss the acceleration of the gsr tranny

The Gsr Imo is the best compromise for a street car.

 

Something a bit more streetable would be the LS. For all out, I would suggest a B16 with a quaife. Ratios are similiar to a B18C5 but available in cable(If you have an EF) and the diff is much more durable.

I have had an ls tranny on three turbo cars the same one had no problem with it. I have heard many people with b16, GSR and Type R trannys blowing up i have also seen too many type r's go down at the track due to trans. I have had gears switch some ls and b16 and have had no problems with it got a quafie too and love it. But everyone here have there own fav so you choose

 

Does anyone here know what the rpms would be on the LS and GSR at say 75mph on the highway?

 

I have driven an LSVT turbo with an Si trans, ITR trans, LS trans, and a GSR trans. GSR trans without a doubt.....I chose a GSR and LSD combination for my turbo LSVT.
