ToplessZ Posted March 11, 2004 Share Posted March 11, 2004 Ok what fpr are you guys using. Should I go with a specific one for my 81 zxt. Looking for something inexpensive maybe from ebay. What recommendations do you guys have? Quote Link to comment Share on other sites More sharing options...

SleeperZ Posted March 11, 2004 Share Posted March 11, 2004 I spent the big bucks and got an AEM universal. It has 3 different return orifices to tailor your regulator to the pump flow. I went with it because it will regulate over a wider range of pressure, starting low at 20 psi. I used lower than stock pressure when I'd just installed larger injectors but hadn't leaned out the ECU yet - adjusted fuel mixture by lowering fuel pressure (interim setup, no advantage to larger injectors yet). I found a cheap on-line source, and got it for $170. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted March 11, 2004 Share Posted March 11, 2004 For low price you can't beat the MSD adjustable, boost referenced regulator: http://www.overboost.com/obs/product.asp?pid=2628 $55.10 from overboost.com. The only downside is it's adjustability range, I think it only adjusts from like 30-50psi, which is only about 10-15psi over the stock fuel pressure. I would think that would be fine for most moderate applications though, and if you need much more than 50psi you should probably be running bigger injectors instead. I know most of the guys on here running adj. FPR's are usually running low to mid 40's for pressure. Most other units cost 2-4 times as much. And it is MSD so it should be a quality piece. This is my next upgrade. Quote Link to comment Share on other sites More sharing options...
