Im gonna upgrade my 90TIIs fuel system. I was gonna buy 4 720s but then I talked to RC eng and I think I want stocks in the prim. and 900s in the secondaries. Do you think with a S-afc I could control these and tune ou the stumbling I think i will have?
What about the e-manage system?
thanks

You planning on making over 400hp?

300 at the wheels, would be ideal. Im trying to get as much power with the stock turbo<hybrid of course> and keep the stock driveline. So what 280-315 at the wheels. I want to keep the 550s if I can. I wasnt sure if the 720 were enough. May 800s in the secondaires? Ill see you sat ted. You can fill me in more about options.

720's are easiest to install.&nbsp They can support 400hp to the flywheel.&nbsp If you're not planning to make any more than that, running larger fuel injectors are a waste of time.

Catch you this Sat!

RC told me that the densos would most likely be low impedance. I have a s5. I need to contact rx7.com and make sure. You really think 2-550 and 2-720 will support 400 flywheel?

Impedence won't matter - it's just a matter of "inserting" some resistors in the wires.&nbsp RC can go **** themselves if they said it's a problem and you need "their" injectors.

2x550 + 2x720 is not enough fuel injectors to run 400hp at stock fuel pressure levels.

so maybe 850s. RC said they could build me 950s out of the 550s I have for 300 a pair. It alot cheaper to do it that way instead of of 4 720s or even 2 1600s. So you think I should get 2-???. I think I want the denso pump RX-7.com sells. I thought about the walbro. So with a denso pump, rising pressure reg, and let say 850s. could I make 350-400 flywheel hp? For the extra $50 I can get what eversize injector I want in 10cc incraments.
thanks ted
