replacing an inlet manifold is basicly a form of pulse tuning, make sure you get the volume of the inlet box correct, slightly too big or small and it will affect the engines performance.

I did all of these calculations ages ago, its actually quite hard to get this measurement perfect from ust using a hollow box. Here is the one I designed, never went into manufacture properly due to costs. Did make 2 nad one is fitted onto a c16xe Nova with omex management and cams and it made 161 bhp, same spec with a 'box' type inlet struggled to make 152 bhp and the power and torque curves were far better with the 'tube' design:




if you need any spec/advice let me know.

No you cant im afraid ..Nothing changed to the looks so far, im going to invest in a set of Steiny skirts alright but that'll be about the limit...Maybe a C20XE in the near future....Dont worry i wont go too mad, she's being well looked after anyway
