450cc Injectors -- What size RRFPR

No, it's a different one. I think the one you're referring to was running a 14B. Where the one I am talking about had a 16G on his setup. The one who decided to try his hand at a DOHC motor install, after he blew the SOHC motor.

That is the turbo I have, and he never said anything about there being anything wrong with the turbo... I guess now I may have to look into rebuilding the turbo

How do I go about lowering the base fuel pressure?

you get an sfmu or you get an aftermarket fpr and fmu. i am using the sfmu because it does both base and rising rate therefore eliminating extra fuel lines, npt fittings, space, and weight.

Wich one? The 14B or the 16G?



By modifying the stock regulator with a B&M command flo unit for a mitsubishi eclipse, or removing the stock regulator, and installing an aftermarket adjustable regulator with a fuel rail adapter. I was lucky to get my hands on a parrallel fuel rail, from an early 3.0L motor. All I had to do was cut the tube that the regulator fitting was on, and clamp a 5/16" hose onto it.

I'm running those Ford 30lbs injectors on my SC'd motor with an SFMU and the Walbro 255. I've yet to get past 5lbs, mainly because the entire rest of the car is in need of work to the point it scares me.
I set base at 36psi initially, which came out rich on a Dawes A/F. I think 33-34psi will be close to spot on.

31.5psi got me the best 1/4 and traps on ford 30# injectors and also a 12.7 a/f on the wideband near redline. Leaner went slower.
I kept the same base pressure turbo and adjusted the tip in setting for when boost came on.

I have the 16G turbo, my brother-in-law is going to take a look at it on Monday, he's a mechanic with much more experience than myself with turbos.

I'm going to take a look for the command flo regulator, or consider the adjustable fpr, a sfmu I think is just too expensive for what I can afford right now, I know it's definitely the most accurate way to go but I'm on a tight budget.

Unfortunately I just let a set of 6 30# injectors go on eBay because I forgot and the auction ended last night... I'm sure more will turn up.

Thanks for everything!

Those injectors are easy to get ahold of. I got my set of 8 for $5 apiece from a local guy. It helps that Columbus is sort of the Mustang capital of the Midwest.

[gorf1000]

Yah, it's probably easier to find anything foreign in NJ, everyone seems to love little imports around here. I'll have to call up the local yards and see if I can find anything unless more pop up on ebay...

I'm getting closer...... If I ever actually get this thing going I'll be sure to update with some pictures...

[Ondonti]

what does this commander flow do?

If you dont have a rising rate oryou dont have modded computer (for fuel instead of rising regulator) then you cant turbo.
You can also do extra injectors but you havent mentioned that either.

[mwinkle353]

The B&M Command Flo unit is just a kit that will make our stock fuel regulator an adjustable one. Harv has installed one on his lebaron, with great results.

He'll still need an FMU of sorts, to go into boost conditions. But at least he'll be able to adjust his base fuel pressure enough with this and his larger injectors.

[gorf1000]

Sorry, I was eluding that I would use the command flo with the stock regulator to adjust the base fuel pressure (I'm going to get 30# injectors since it sounds like the ones that I have would be too difficult to make work properly), and I'll use a RR FPR to handle the boost condition.

With that I should be able to take care of everything, now I just need to check out the turbo and see if I need to rebuild it.

[Ondonti]

well your turbo isnt the one I was thinking of before (the 14b that Im pretty sure was overspun).

Not really. The guy who had that setup sold the turbo and it worked well on another motor. Just not a 3.0L motor.

It was obviously just too small of a turbo to work on a 3.0L setup.

Hey, that guy with the turbo acclaim was one of the pioneer Turbo 3.0 people, don't put him down.

There are 2 people who had turbo acclaims and 1 of them was NOT the person you were talking about.....he decided to see what a 14b would do when you rev up the engine and dont have any intercooler hosing hooked up....hello overspin. His car never ran correctly.

The guy who built the turbo sohc and then tried the dohc project is a different person. He actually had a turbo 3.0 that ran.
