If i want to do this, i need a larger butterfly. Are any vehicles in my junk yard compatible with large enough butterfly's that can drop right in or do i have to buy one from an aftermarket site?

Thanks guys.

I did some research about this a while ago. You have to make your own. Supposedly it's not hard. I ended up just removing the lip at the bottom of the tb.

Removing the lip at the bottom helps though.

That would probably hurt it more than help wouldn't it?
