2.8 turbo on a 3.1 motor

[mudgrip4]

This is a common enough idea but has anyone actually done this mod? What was the power and torque curve like with the 2.8 turbo fitted onto a 3.1?

Ive heard it done the other way with better power at top end.

Mine would spin the wheels on bitumen at take off. Still drove beautifully over all the rev range but I think over 120ish it was losing puff.

Very hard on clutches having sooooo much torque off idle.

Love it though!

Interesting - sounds like fun.

The way to get an extra 500rpm usable top end is to advance the pump timing.
