Thread: turbo?!

Depends on your goals but one could get the Z3 kit and be happy with it, it has had some good results. The cartuning kit is not crap either, I just wouldn't buy it brand new.

Your tranny will hold up for a while if you get this and don't drive like a jackass:
Z3 turbo kit
42.5# inj.
DIY intercooler

That should be an easy 300whp and up if you do some tuning...

The two kits are actually comparable to eachother in terms of potential power. The Z7 kit was just the original kit made and the Z3 kit came out later offering a few other refinements and cost savings over the Z7. The wastegate location changes on each kit. The Z3 has the advantage of open dump wastegate, after the desired boost is hit, the wastegate opens and extra exhaust pressure is bled directly to the atmosphere. This is better because the boost levels will not fluctuate as much since there is no backpressure and a 2.5" downpipe from the turbo becomes more like a 3" downpipe when the wastegate opens. I would say either kit would work well up to 450whp, after that the stattama kit would be the better option.
