This well loved *cough* Vauxhall tuning company is selling enlarged bore throttle bodys claiming 15% more torque at low revs. This is not a multi-throttle system just a single body straight swap with oe.
£345 + ur old one.
My question is would it be possible to enlarge my original tb (xe engine) by boring it out with some porting tools, saving me a lot of mula. Not that i would concider buying there product anyway.
Is 15% gain possible mmmmmmmmmmmmm
i can hear more Regal slating lmao :
