Shoot me an email and I'll price out everything you need to convert from the K-series turbo to a Garrett GT. 420+rwhp on pump gas is simple on even a flat manifold 930/C2T with EFI (headers, muffler, intercooler, stock cams and intake ports, single plug).

Why a T04 flange:
- The customer is a bit of a power junkie (aren't we all?). We built the system to fit a Garrett GT40R in case he wanted/needed more turbocharger -- so that meant making the exhaust accommodate a big T04 flange, and spacing everything to allow a bigger compressor cover, too.
- If we were disappointed by the performance (response, power), or we believed the exhaust backpressure was too great despite the 1.0-ish A/R turbine housing -- I really wasn't sure about those stock heat exchangers' and their effects -- it would be simple to bolt in the larger turbocharger. No problem, the GT35RS worked really well.
- the cat-delete pipe feeding the turbocharger was closer in circumference to the T-04 flange's opening than the T3's opening, so it seemed natural to use the larger flange.
