Garrett gt2250s stage 3 from 90k-100k … zero major mechanical issues.
I got a 2867R with two-port and a recirculating valve. I wouldn’t say it is snappy but spool it up to 3k rpm’s and then just roll into it and it’ll take off. When you shift you’re above 3k so just roll back into it. On 93 I have 350 and E40 I have 420 but I like how it drives.
I have a 2860 with junits elbow tuned by JST. It spools to 20psi by 2800rpm, and pulls all the way past 6k. If you have the money, 2860 beats powermax in every way… okay maybe PM spools slightly faster, but the 2860 is making 40-50whp more power AND it extends the powerband to 6k+.
man those EFR turbos were fucking lit.
I put one in mine, ~225 hp @ 11 psi, starts spooling at 3000 rpm
I was running the GT2860RS turbos and they’re making the power you’re aiming for too. I can say I was spinning tires in third gear and hitting boost around 3400 RPMs. They may be slight older and won’t spool as fast as the newer GTX, but that particular turbo will still kick in the pants and not drain the wallet. And they are ball bearing turbos too.
Quite a few years ago I bought a Borgwarner EFR6758 for my build, and it was a stellar little unit.
Yes
The Stage 1 Garrett doesn’t provide enough of a bump from an OEM is38 with a lifetime warranty to justify the expense.
3 weeks after posting this and my turbo locked up on the hot-side... Car ran 10 degrees hot out of nowhere and then a loud pop followed. Checked everything and it seemed okay. Except the turbine wheel didn't want to spin. Absolutely locked up. Friend driving behind me saw more black smoke than usual during the pull followed by a blue-white "puff" which we agree is when the turbo died.
