In narrowing down the ~600whp turbos is there a clear winner between the Gen2 3076/3576 or Gen2 5862?
I'm on the same boat between a gtx3076r gen 2 or a 6062 both with a 1.0 ar.
I havent seen a dyno graph of a gtx3076r in the 600's most mid to low 500's on 4 cylinder cars.
I cross shopped between these exact same turbos. I ended up selecting the 3076 with the t4 1.06 housing. To note: the GTX are water cooled and do not have a boost reference on the compressor housing while the PTE is only oil cooled and does have a boost source on the compressor housing.
The 4 cylinders are running smaller A/R's so they will have less flow up top in combination with the smaller engine would net smaller results. The 3076r with the T4 1.06 is rated to 750hp.

FWIW, I'm now running a Gen2 GTX3576r .92AR on my MOTIV manifold. It's fully spooled up at 3,400 rpm and, at 22 psi on 93 octane pump gas, I'm seeing 512 whp/495 ft-lbs on a Dynojet.

Good discussion! I appreciate the input, and I'm glad I'm not the only one having a hard time with the decision. I've mostly been set on the 5862 but had considered the GTX variants as I've always preferred a water cooled center section. I did notice the GTX kits have increased in price since the initial standard pricing sheet where the 3076 was about the same price and the 3576 was $1-200 more. Now they show to each be ~$2-300 more which is harder to justify for what probably equates to a very similar output.
From what I recall, a 3076 and 3576 actually spool the same, so the question for most will be 3071 Vs 3576.
Stock exhaust outside sound clip. It's pretty quiet, but if the sleeper is what you're looking for, it's perfect.
3.5 in single exhaust that IMO the best sounding exhaust available. Also you can’t beat the price, it’s only $799
Not certain, but I believe 4th. I'll check with Jake H. who had it on the dyno to tweak the tune.,

Received my kit this friday with the sxe 257, extremely please as well. Will be installing it this coming weekend.
Figured out your power goals first then pick a turbo for that

Power goals and power characteristics. If you are working with a tuner, good to discuss with them (assuming they are a good tunah ...)
