what kind of race gas can i run and at what boost level by the way how is that gt 6152 is it the same as a te-44

What kind of timing are you going to run at the track?
You should be able to run unleaded a couple times with out killing the O2.
The max boost you should run is 23 to 24psi. The stock turbo will not do much of anything after that. Do not do anything with out a scan tool.
The 6152 is much bigger than the 44. It requires much more stall and more injector. The 6152 will make about 100 more hp on the correct combination.

Best regards,

It is hard to say.
I have run 25 gallons of c16 before changing o2.
I have also heard of people hurting them the first 5 gallons.

thanks for the help

With timing that low you should be able to run 100UL or 105UL and 20# 22# of boost. If you want to use leaded race gas, get a race chip. I have had Delco O2's last 15 gallons of 116 and I had 1 code before I even made a pass! Also, if you do not have a scan tool DO NOT go to the track.

I agree, no need for leaded race gas with a stock turbo and that timing.

Walk the boost up from 19/20 to 22/23 etc.

Use the 100 unleaded or 104 whatever they have available.

And make sure you at least have a good KR detector, scanmaster would be even better.

In this summer heat, there's no reason to try running more than 20# or so with a stock turbo as there will not be much gain, especially if you are not good at tuning, and without a scan tool and a scan tool that records your run I would not push it much more than that. With no way to watch knock or O2s I would not even go WOT!
