Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Intake & Exhaust Upgrade for GDI

I suspect a remap of the GDI would be very difficult. The system is much more complex than the previous system and I have been told it requires multiple timed pulses of fuel to sort of layer in the fuel air mix during the stroke.

A sports exhaust system may be possible but I see that the manifold is very short and the cat quite close to the engine. My feeling is that disturbing this setup too much is just going to create problems for fairly limited gains. In any case the exhaust manifold doesn't look too bad anyway even though it is very short. Perhaps a 200 cell cat and a more open silencer may render some small gain in torque in the mid range, and very little at the top end (without freeing up the intake). I feel there is little to be done on the intake side, which would release some top end ponies, until some very clever and sophisticated work is done to provide a throttle body kit.
