She has it boosted when she runs on the track, and turns it down when driving the streets. I've never met or talked to her, but I do see her driving every once in a while, and I have seen her race. She got low 10's when I saw her, but her best is in the 9's.

fine Ryan.

My comment on the TB was quite brief and was just meant to point out (to those that have followed previous discussions on TB size) that a 1000 whp 2.0 liter engine can use a 68mm TB, therefore a monster TB is totally unnecessary on a 160-180 whp 2.5L engine.

Given the shape and size of the K series intake manifolds, it might be VERY beneficial to use a larger throttle body. Its not just an output thing.

Say i was to do the swap for the ZE, what is the cheapest way to get it to where I can easily keep up with 5.0 GT's? Also to keep it on street use (daily driver)

i think i remember reading that the stock throttle body on the 1.6 sohc was 60mm and could safely be overbored to 65mm....would this be at all beneficial to an engine with only an intake and 2.0" exhaust set up?

maybe i'll give it a whirl just for fun [img]shrug.gif"%20border="0[/img]
