ElTeeFauci is on a distinguished road
Default
so this:
http://rx7.com/cgi-local/2ndgencalc.cgi

tells me that 720/720 is able to support 350 at 85% duty cycle...

If I keep my 720 injectors (currently secondaries), swap them over to the primary rail, and throw in some 1000's on the secondary, are there issues when the secondaries come online? The only real reason I'm asking is that the above mentioned calculator says so... but I can think of people running even 1600cc secondaries without issue.

Guess its all in the tune.

Anyway, getting the engine tomorrow... cant wait. Though it will be a while until I swap it in. Gonna throw in new front/rear main seals for the hell of it, order some new exhaust gaskets, and of course a pair of bigger injectors. standing by for recommendations on injector size. I'd like them to fit the stock secondary rail.
