throttle body in my vt

[fasamr]

can i change the throttle body to bigger size body, what difference will itr make any increase in HP, please explain the effect after changing tb also

The consensus is generally no. Increasing the TB doesn't give any gains on an un-worked engine, and often causes tons of idle and fueling issues.

If you want any real gain out of an Ecotec you need to spend serious money on either stroking or FI. Most people would say just buy a V8 (that's what I did )
