I have been ask to twin turbo a stock ls6 in a gtm supercar. Owner wants 700 rwhp. Any recommendations on turbos to use for this. I was leaning towards so s300 62 mm comp and the 68mm turbine but if there's a better choice or I'm going to big let me know.

over kill but some some small BB 60's would do the job easily

Might be a little excessive, but it leaves some room to grow. Later on, a 4" stroke crankshaft turns that ls6 into a 383 stroker, and then twin s300's are perfect.

I'm running twin 6266's in my GTM, but it's a 6.2L. Just got it started and don't have it on the road yet, but S300's were a bit big to fit in the engine bay.

For only 700-800whp T3/T4 50 trims would spool better than Borg stuff. On my 6.0 twin 60mm S300s make only 5psi at 3500 and 51mm S200s make only 8psi at 3500. No point in S300 turbines for only 700whp unless you specifically are looking for slow spool.

PPI typhoon: I actually showed him the picture of your car when we were talking about this. I was trying to push him towards a single but he is dead set on twins. He also wants air to water. Do you think there is room to put dual cores in place of your charge pipe tubin on your car.

Anyway I think I'm gonna do two of the hurricane series cause he likes the polished housings. Would the 6265 t3 be stupid back pressure wise or should I go 6665 t4s so he has room to grow later.

Holy **** that is bad ***!

Do the T4's.

Sorry I missed this message, but yes, that type of configuration is possible:



My setup is essentially T3 sized housings. They are completely fine for that power range.

Here is another option I was trying out with different outlets to get the longer pipe for use of the MAF sensor.

That is almost exactly what I was thinking of doing on this car. I was planning to just join the two together on the intake manifold side and make it a single 4 inch outlet but I hadn't thought of the maf issue. Guess I'll just kinda copy your set up since this guy is dead set on a2w. You have one bad *** car by the way. It looks and sounds awesome.
