The turbo is a little bit small for your application. I recommend at least a 62-1 or anything up to about 70mm.

 

I do plan on upgrading eventually... but do you think this turbo could possible net me a 10.80? thats all im looknig for. lol. Also long as it will still work. haha only gonig to run 12 pounds on the stock shortblock

 

So im guessing this isnt a good question?

 

I have a friend who has about the same turbo, full weight car though, but with Victor Jr's and he runs 10's all day long, turbo is on a small side though, he start loosing power at just around 5,500 rpms. Good Luck!

 

So the turbo is on the small side? But will pull till about 5500. Should i go with 3.08 or 3.27?

 

I would go with 3.27, 3.08s are pretty long.

 

got a lead on a set of mark williams 3.31. Going to go with them.

It is on the small side, yeah. But my buddy's car pulls nice to like 6,500 rpms, just on the dyno sheet You can see it dropin after 5,500.
As far as gears, those 3.31's should do the job
