There are a few aftermarket 65-70mm throttle bodies available for the RWD SR20 and RB20, and they are a direct bolt-on.
Look into a crank scraper.
Sorry for sidetracking the thread, and this may have been answered before, but if I plan to retain the stock VE ECU with the rev limiter and all (however the VVL would be set to engage at around 4500rpm), would the N1 cams still provide any gains throughout the rpm range as opposed to the stock P11 or possibly the regular SR16VE cams, or do they mostly make power up high?

Hmm may want to bump up VVL engagement to 4800 or so, unless you've found it makes its best power on the dyno (mine makes the most peak power when VVL engages at 5200RPM, I lost some power when I went down or up)
As for the stock VE ECU question, from what I recall, the fuel cut is fairly low. Do you know which vehicle the VE ECU came from? We may able to look it up. I thought I remember it was like somewhere at or below 7500RPM, may have seen that it was at 7100RPM even. It all depends which vehicle your ECU was from if you can find that out.
