Throttlebody for EG

Or farking sorry ... I didn't know it was so small. Other than the size dimensions, TB upgrades is still pointless. I don't see why it needs to stop at 70mm, might as well go all out and get it up to 100mm and see what happens. :roll:

yeh good one, why not try boring it out to 2 inches!

you will notice a difference in throttle response but this is all relative to what mods you have done. i experienced alot of loss in low-down power, but gain heaps in the top end! this is on a b18c! going too big is not wise because your engine cannot produce enough vacuum to move the air!

hey there...

this was on my DC2....a stock B18C throttle body is 60mm, i bored it out only slightly to 62mm....same as ITR TB. experience a fair difference in overall response. was a good mode...but i had intake/headers/exhaust as well!

cheers
