ok i have a 1990 crx si with full exhaust,and i got a great deal on a adjustable fuel pressure regulator.

my question is what psi should it be set at?

 

Stock setting around 35psi

 

Don't put it on. Leave the stock one on there. Adjustable **** is meant for cars that visit the dyno

 

well i was bored tonight and i put it on.....thats why i was asking, and i guess i shoulda also stated the fact that the car will have a turbo kit put on it in two weeks and i just wanted to go ahead and throw that part of the kit on to pass some time today.

i also forgot to say it is a high-rise fmu unit that raises the fuel pressure with boost

and looks just like this

 

Yea that is the typical made in china Ebay one. There okay.

 

Seriously man, it's 2010. There are WAY better and CHEAPER ways to tune a turbo car. FMU's were **** back in the day, and they still are now.

 

^ old school in the house! Back then we ran Porsche FMU's hahaha

 

yeah i know i know....but this is just for a lil bit of fun.
i pulling the d16a6 out putting a d15b7 (with 83000miles on it) i got for $100 from a friend thats doing a k20a swap in his del-sol.
so while the d16 is out iam goint to build the hell out of it, but while i have the d15 in iam just play with it.....i mean hell he gave me a old turbo kit he had laying in his shop.

 

That fuel pressure regulator will not provide enough fuel even for a low boost set up. Those are 1-1 regulators. For every 1 pound of boost, they raise fuel pressure 1 pound. The rising rate fuel pressure regulators we ran on our "old school" home made turbos were 10 or 12-1. So if you run 5 psi that regulator will give you 5 more pounds of fuel pressure. A Vortech rising rate regulator would give you an extra 50-60 pounds of fuel pressure. BIG difference.
