My engine rebuild is almost done with 8.8:1CR. My injectors now are currently 270cc. I plan on running 15PSI of boost after break-in. I will also only be running an FMU.

So... I know there is someone out there with a similar setup. I'd like some experienced knowledge on this if possible. My current setup is in my sig.

-270cc injectors (Upgrading to 550cc)
-16g Turbo/8 lbs (Upgrading to 17lbs with mechanical boost controller)
-Custom FPR (Upgrading to S-FMU)
-Wiesco 8:8:1 CPR Pistons
-Eagle H Beams
-ARP Main/Head studs
-Centerforce dual friction stage 3

Please...do yourself a favor and upgrade fuel management to at least an S-FMU if you don't wanna risk blowing up your new motor

EDIT: bigger injectors too...you'll be at max duty cycle by 10psi or so...hell, I have green top 440's that technically are done at the 12-13psi range. meh, to each his own I guess

Ok, this is info that I didnt know. I will get my friends 550's off of his RX-7. I also dont know why an S-FMU is so much better than a regular FMU. Correct me if I'm wrong, but isnt the only difference between the two is that you are able to adjust the idle fuel pressure.

I'm open up to everything because to be honest, I dont really know all that much about what I'm doing, so the help is greatly appreciated.

OK how are you going to use rx7 injectors??? I mean. theres 2 550's ie:primary injectors.

An sfmu is adjustable. FMU is not. Thats what's better

With larger injectors you need less fuel pressure. Does that not make sense?

you can not run a fmu with bigger injectors . with 550's your idle should be around 15psi . your fmu will be at 55psi at idle

Well, the reason I'm going 550's is because my friend is going to basically give them to me for 50 bucks. And I'm looking into getting an s-fmu now. Dont worry guys, I dont care if I look like a tard asking all these questions, I just want it to get done right.

I have a killer deal on an SFMU with every disc/spring for it in the F/S section!
