Really ^^? Have you read any of the thread at all?

Of course all of this is pissing in the wind with bandaids. The crap in the rest of your post about doing things right, and then saying you'll "eventually" get a real ECU just don't mesh. Not trying to be rude, I just know how much it sucks to swap motors.

The injectors are currently being cleaned. And "eventually" means when I have money in the next few weeks. The car's not going to be running until I have a MS.

I don't plan to or ever planned to run with bandaids.

I want to run the RC's because I've heard they have better flow. But I just spent the cash to clean the RX7 ones, and the RC's were cleaned recently but I don't know how long ago (the seller claimed they were cleaned).

oh...ok, different interpretations of eventually, I woulda inserted "soon" there.

Had you mixed up with some bandaid newb, sorry.

Yeah, I'd use an AFPR and the 360s since you're upgrading the pump anyhow, unless you need more headroom.

I shouldn't need too much headroom. I'm just running a GReddy turbo with the ETD mani. I think 360's with a 45-48PSI base and a 12v wired 190 fuel pump should put out nice solid, steady pressure.

It's being built as a track only car so a wired pump is not a big deal for me.

Mine is a street car and mine is technically wired (jumper in the diagnostic box for MS), no problems.

Ya, I have an external relay all ready to go. Does anyone know what the stock fuel pump flows at 12v?

I got an Aeromotive 1:1 with adjustable base pressure for about 100 bucks IIRC, with 6AN fittings. I found an adaptor from my DSM fuel rail to 6AN and ran with it. A liquid filled guage was like 30 bucks or so. Worked great, good construction etc. No need to cheap out on one really, even on a budget.

Another thing I dont understand is why so many go with 190 pumps. A 255HP is almost inconsequentially more expensive, because the Mustang guys use them all the time. Reliable as hell too. I am sure there is a reason, I just dont now what it is.
