Motorsports has a "rising rate" fuel pressure regulator for a turbo (P/N 11-3074) for $229 malebitchslap.gif . I am not aware of an additional source for your turbo application.

If you keep stock injectors on your 280zxt then RRFPR would be the answer(it would max out your stock injectors). If that is the case then you could also check E-bay. They have ones from time to time.

Now if you are going to install larger injectors with your mentioned mods then you would want to buy a Adjustable Fuel press. regulator vac. indexed 1 to 1 (as compared to RRFPR 4 to 1 thats 4 psi. to 1 of vac.). You can buy a AFPR from Jegs for around $114 to $129.

Sure appreciate the help. Anybody ever used one on a Z before? Looks like the mounting might be a little akward... and I didn't see anything on their site explaing the different ratios, 4:1 - 12:1. How do I decide which one I need?

 

One more thing, can I test the FPR I've got now?

4:1-12:1 is fuel pressure:boost ratio. so on 12:1, 12psi raise fuel pressure per 1 pound of boost. Too big IMO. I say 4:1 is plainty but I don't know how your car is set up so I can't tell you.

 

I've not seen it on Z yet(I've seen the cartech unit before)but I just saw one on Vtec SI with drag 3 kit. he had it mounted on the firewall.

Get an aeromotive FPR, you can get one from summit.

 

Mine is ajustable from 30 to 70 PSI base with a 1:1 boost/vac ajustment.

I talked with a guy that has a MSA performance rising rate pressure reg.(if your gonna use this one) his email is mxs666@att.net I was interested, but I researched it further and talked around, and found out it wouldnt be good for my setup. He should still have it if your looking for the MSA reg. at a lower price than MSA's list price....he said it was never used.

I've heard the leaking problem with Aeromotive unit but I don't know, I'm running SX performance which seems to be same thing and it doesn't leak :confused: ebay is one good place to look too. I paid $85 for mine

Hey, you could look into one from a Mitsubishi Starion/Dodge Conquest, apparently they are rising rate from the factory (1# of pressure for every 1# of boost), just a thought.
