Make sure the crank/valve cover vacuum system is properly plumbed. It actually makes a difference on an SR.
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 cams or possibly the regular SR16VE cams, or do they mostly make power up high?
