CGA Throttle Body

[AJC]

Looking to upgrade said T/B on my CGA, in prep for my impending turbo conversion (job front is looking good frank, so should be able to sort out that mani in the next couple of weeks ) any ideas on what would fit or be worth it? i was thinking one from a QG18 maybe?

nice one AJ i get on better with the stock t/b when boosted (and the SR20 when n/a) there is very little difference in power output whether its 1/4 throttle or full throttle under boost tbh, my SR20 setup was akin to an on/off switch (because its being crammed in under force).
so the throttle position sensor is probably more on target with a smaller t/b

Ah, thats good to know, just wasnt sure due to mine being the CGA, didnt know if my T/B would be a restriction, but as you said with a bit of boost, its doubtful that a bigger diam T/B would make any diff with low boost.
