I’ve got a Garrett GT4088R turbo for sale. I have used it for about 200 miles … Made to the track once last year and ran 12.05 @ 130 mph (zero traction). I got a pretty good deal on 64mm so I will be upgrading.
This is the dual ball bearing model (which does help with spool) but it is a big turbo … Typically around 5-6k RPM on my car.
My car made 750 to the tires with this turbo at 30 psi.
Any questions let me know.
