Ok. I need to know what kinda tranny I need to hunt down. I am trying to go LS Turbo, and I have the Motor without Tranny. I've been told to go get a GSR tranny, an SI Tranny, and an LS tranny.

Here's my question. Which one will work out the best for me. I've heard that LS is best because the gears run longer. Someone told me GSR and SI are better for for NA because the gears are shorter.

What would be the best for me?

 

The "best" would be to build one to fit your exact needs. If you just want to bolt one on the look at the gear ratios and decide what you will like the best. Also use the search function this has been covered at least 10 times in the past 2 months.

 

just get a GSR tranny
