Ok, so I'm looking for 220NM+ from my currently stock 194NM 206 GTi. I'm going to be getting a stage 1 cam soon, and I'm thinking of using multiple thorttle boddies as well.
I've worked out that 2 65mm throttle boddies have the same cross sectional area as 4 48mm throttle boddies. Also, I can get as many 65mm ones as I want for free, and the throttle linkage will be easier.
I'll have the manifold made up, and I already have the CAD drawings for the intake ports and bolt holes. Anybody know of somewhere that can do the cutting and welding for a reasonable cost?
