Results/Update - FTS FPR

[DiabloRT]

Full Throttle Speed FPR

Despite its short comings as far it needing to be modifed to be installed, it performs well.

With the stock regulator and the Walbro/Holley 255 HO pump, the base idle pressure in my 1G was 43psi with the vac connected.

The FTS FPR has allowed me bring the base pressure back down to 28psi vac on / 38psi vac off.......back to factory spec. Which makes me very happy.

The car seems more responsive and I am sure I will see better gas mileage.

is this the new "bolt on" regulator, and if it is how much modifying was needed? I am looking to get a regulator soon, and was looking at these guys due to price. did you also get their fuel pressure gauge, and how easy to install is it?
thanks

1. I had to grind a small amount off the casting slop on my rail in order to get the FPR's adapter plate to line up with the mounting holes. This mod is very minor and simple.

2. I had to grind 2 more spots on the rail to allow clearance for the supplied nuts that hold the adapter plate to the reg. Some people use the stock regulator bolts instead.

3. The most superior plug wire at the coil hits the adapter plate. I ground alot off the adapter plate inorder to get it to fit.

Does the regulator work.....YES It works well.

I just wasn't thrilled with all the grinding.

If I were to do it again, I would go with SBR adapter fittings and lines aka adapter kit and the Areomotive regulator (remote mount)

ya i have the SBR package with the areomotive FPR and i love it it's a pain to install but no worries ever after that

Ya any SS braided line package with an aeromotive is great, the FST one is good for those on a budget who don't mind a little "modifying" to get parts to fit.

Diablo, what years is your car? I thought that the 2g's didnt need any modification but the early 1gs did.

This reg is not new, its been around for a year and a half. And there are tons of write ups on it, mostly all of them are on Dsmtalk.

Mine fit fine, the adapter plate was not perfectly round and had a nice cut off the the top right half so that the plug wires would clear. Around 30 minutes and it was done.

90 is slightly different than 91-94. Other than that, this was a super easy install, and just use the bigger bolts supplied and the factory ones.

The liquid gauges have been causing cold to warm reading problems, since day one. Just tune it when its cold and do not worry about the changes.

The FTS regulator went on like butter and works great for me. I used the stock mounting bolts and just decided to relocate my coil pack to get around the wiring issue. I removed the rail and reinstalled it with no issues.

It is a quality piece - I agree that the adapter plate leaves some to desire, but it's a great piece overall, especially considering the price and the fact that you don't have to dik with AN fittings.

Do 2g's need any modification for a proper fit?

Not for mine.

Pirate-
Overall, would you say that you are satisfied with the regulator? Im about to buy a walbo 255 and am unsure of what regulator to get. If this thing performs well, it sounds like a real good deal.

I used a liquid filled guage. The important thing I found is to adjust your pressure when the engine has sat overnight and you first start it up in the morning.

I was very satisfied with it. It is alot easier to install it with the fuel rail off of the engine.

So if you are going to remove the fuel rail, I highly suggest you replace all the injectors O-rings while your at it. And then do a boost leak test to make sure they are seated properly

If you install it on the car make sure you put a rag under the end of the fuel rail to catch the bolts if they drop. They are SS, so a magnut won't help much here

I have the B&M Fuel pressure gauge which mounts on the fuel filter outlet banjo bolt.

When I did the FTD FPR, I got a liquid filled Marshal guage from them. When I my install, I did not have an elbow, do I could not mount the gauge on the regulator.

SO......I swapped the liquid filled gauge with the one on top of the fuel filter. I don't think I will have a huge change in readings because it should be isolated from the heat more...since it is not on the motor.
