I was wondering if you guys are aware of a large throttle body that bolts on to a 99 1.8? I have investigated getting it bored out and so on but would obviously prefer a bolt on upgrade if possible. I am after something around 70mm for a supercharged application. Any help would be much appreciated. I think I have read something about mustang units fitting - is this true? Thanks all.

 

I have one but truthfully I have no idea if it's direct bolt on to stock 99 manifold. I run a BEGi manifold. Mine also doesn't have integrated IAC.

 

a big TB does you little good if the inlet isn't matched...
