Prospecting for a turbo

[jkoth0726]

Does anyone know which brand for a turbo will be good for my L36 3.8? If so, where would be a great place to get it? I'm not looking for a kit, cuz i have mechanic to do all the work for me to include the welding and power tuning.

Garrett GT35R is pretty badass (t3, .63 a/r, 68mm turbine).

Turbonetics 62-1 (t3/t4, .63 a/r) is becoming more popular and is capable of making very good power on a stock motor. A few dudes on FTV6 have them and like them.

The Master Power T70 is a decent unit for the money as well (t4, .68 turbine, .70 compressor). Also know that the MP T70 is a tad too big for stock heads/cam and stall. It takes quite awhile to build boost. I know this because I have one, I use nitrous to make up for boost lag and my stall helps quite a bit as well.

This is true lol. My car feels stock halfway through the RPM range but then it kicks in. Andrew told me to get a 3000 stall and it would wake it up a bit.

I have a 3200 stall and it made a big difference.

Re: Prospecting for a turbo

I was looking at pricing online and saw that the Garrett GT35R runs for about $1300, while the Master Power T70 is only about $700. I hear that Garrett turbos are arguably the best quality, but is it worth double the price? I assume the Master Power T70 isnt a ball bearing turbo like the GT35R.

Thanks for the help. How much boost will be safe for stock? Where can i find these turbos?

Correct, the Master Power is a journal bearing. If you have the extra cash, get the GT35R. If I could afford it I would have it.

Safe boost level? Well...thats up for debate. I know plenty of guys running 15-17 psi on stock motors I even know a dude who is running 22+ psi on a stock motor none of which have blown anything up yet. As long as the motor is healthy, fueling is sufficient and the tune is spot-on then 15 psi shouldnt be a problem.

Google it up to find retailers for the turbos.

Re: Prospecting for a turbo

dont forget intercooling for boost levels that high

An intercooler is an absolute must with any conventional turbo setup no matter how much boost.

A simple air-to-air intercooler is more than sufficient up to 25 psi or more.
