Well I have decided to sell my twin GT28R turbo kit, as I have recently gone to a bigger single turbo.
With stock cams it makes 10psi at 3000 rpm and full boost (20psi) at about 3800rpm. I made about 390 rwhp at 15psi and 502 rwhp at 22 psi on 94 octane pump gas. No expense was spared when I built this setup, everything was hand made and TIG welded by myself. It took me over two months to build it from scratch. I took my time and didnt cut any corners. This is a complete bolt on kit with everything included that can be installed in a day or less. If you are looking for a high quality super quick spooling one of a kind twin turbo kit that can make 500+ whp this is for you . This setup should be capable of 550+ whp.
These manifolds will also allow for twin GT28RS (650+ whp) or even the GT2871's (700whp+ capable) to be bolted on, if you want more power.
I will sell it either as the full bolt on kit, or the full kit without the turbo's. There is only about 8000 km (5000 miles) on the setup.
It will include:
2x Garret BALL BEARING GT28R with a .60 a/r compressor housing and a polished ceramic coated .64 a/r turbine housing, the actuators are 14 psi.
custom bolt on adapter flanges inlet and outlet for the turbo's
Two hand built tubular 1.5" .120 wall 316 SS manifolds
Twin 2.5" SS downpipes
3" SS midpipe with second wideband bung
Oil feed and drain lines, block adapter fittings
2x -6AN Water lines
2x 3" SS intake pipes with filters x2,
Modified stock hard water pipe that wraps around the block to oil cooler
Hot side first IC Y pipe where the two merge into one and goes to the IC inlet through the snorkel hole, with Tial BOV flange with blue 4 ply silicon couplers
