slant six build


As the current owner of the turbo setup in that article, I have a few warnings about that approach. I bought the setup from Wayne, installed it, but currently do not have any of the parts from that article on my car. Here's why.

1. Welding cast iron is very tricky. The flange cracked and probably would have fallen off if some other things hadn't encouraged me to pull the manifold. It's better to make a steel adapter pipe with a slant six flange on one end and a turbo flange on the other, and support the weight of the turbo.

2. The Mitsubishi TE04H is too small for a slant six - arguably, it may be too small for the 2.5 Turbo cars it originally came on. It can build 10 psi of boost at 1,500 RPM, which is below the torque converter's stall speed. At 3,000 RPM, it's out of breath. It can give you a monster hit down low, but if you have a serious power lust you will want a much bigger turbo.
