Hi can any one help, whats the best and or biggest throttle body i can fit for extra power to my XR2I. Would a rs1800, or 2.0 16v mondeo or a mondeo st24 throttle body fit. Thanks Jamie.

 

I very much doubt the OE TB is not up to the job. Your engine will only use the air it needs so unless you have changes cams (and mapping to suite) you do not need a bigger TB and it's effects would most liekly be negative.

Think of it this way, if your mouth was bigger could you breathe more air?

NO.

 

I have a chiped ecu, also what cam do you recomend. thanks. jamie
