Hey guys, My mate bought an r32 the other day and was wanting to find a couple of things out. The car kind of stutters shifting and sometimes almost stalls a lights, it seems like it getting to much fuel. The car has a malpassi RR FPR on it and was wondering what the correct pressure for it would be. The cars running 14psi, front mount intercooler and a slightly upgraded exhaust. now the standard FPR on the fuel rail has the vacuum line disconnected i understand this is correct when running an aftermarket FPR so its always open??..

Thanks to all help. Dave

stock fuel pressure is:

when ignition switch is ON: approx 3.0 bar (45 psi)

During idle: approx 2.5 bar (35 psi)

Idling when press reg vacuum hose is removed: approx 3.0 bar (45psi)

and you should remove the std fpr when running and aftermarket item. but yeah running it with the vac line removed will keep it in the open position. but it will be creating a restriction.

Its got a Mines ECU fitted. The BOV is a TurboSmart Type-3. I thought the BOV might need adjusting?? The O-Ring on the BOV screw hat seems old cause the screw hat it stiff to turn.

With the vacuum line hooked up to the stock one, wont it just run normal standard fuel pressure therefore making the use of the aftermarket one useless?

Thanks, Dave.

    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
