Ive used them on exactly that engine mate


right, basically what i found was:

Loss of power lower down in the rev range, i think this is largely due to the TPS addustments no longer being accurate in the ECU as it flows a different amount of air for the same amount of throttle.

Midrange largely unaffected

top end improved SLIGHTLY


Overall i would say that if you are keeping the standard management and not getting it reprogrammed then its a bad way to spend your money.


If you combine them with a megasquirt though or similar, would be a nice solution, they have many benefits over a "normal" set of bodies such as the ability to run an ISCV and the fact you can still run an airfilter at the front of the car.

Secondhand in this country they go for 500-600 quid, i have a set in stock if he wants them, but as i said, unless changing management too, i wouldnt recomend it.
