I looking for the best turbo for my setup, someone can help me and choice between, the new precision cea gen 2 6266 or 6466. Im running a stroker 2.3L, wants like 750whp with c16; the spool of this are very different?

 

I've recently seen a 2.3 dsm go from a gtx3582r to a 6266 and then a gen 2 6266 within a few days without changing anything else but the tune. The 3582 spooled much faster but "only" made 750ish. The 6266 made 795 but was laggier, the gen 2 6266 was able to make more boost and made 830 before blowing a seam on the intercooler.

The 3582 graph had much more under the curve and really came on hard around town. It gets my vote for a street car.

 

That's a great comparo. 750whp out of a GT35R is a lot. I have a 6262 with CEA turbine wheel and a 2.4 and it is nice. I am only around 550whp at 25psi currently. I love the 6262. I don't know if it is still available though.

 

I had a 3582 in my old Talon and it was a very good turbo on a 2.0L. It's not making 750whp..sorry. For 750whp, look at the 6266 and FP3586HTA turbos.

 

 

Friend has a 6266 Gen 2 on a 2.3 and it felt better than cars with 64 and 67.

All were tuned by the same tuner and the GEN 2 had a sick power band.

Made like 75 WHP more than it did with a 6266 GEN 1 with out losing spool.

 

The GTX 3582 made 750whp. Not a standard GT35R. That is a nice comparison except they don't show an overlay to show the changes in power band. Also what were the different boost levels. The Gen2 6266 made a lot more tq than the GTX 35R. So it can't be all bad!
