My R32 gtr is running 14psi.........feels good as

the car wont boost above 10psi and feels sluggish

i pull the car over restart it and its fine again..........

at first i thaught it was the fuel running though it but y is it alright when i just turn it off and start it again

heat related leak??

if this is so what is actually happening, does the computer relise whats going on and change settings?? cause some times i could be driving for 2 hours and it wont happen on a pretty warm day

other times i could do less then 30 min of driving

and why would simply restarting the car stop whats happening??

when things leak they usually do so almost randomly. If you haven't tried to check the tension on ALL of the intercooler pipes then I suggest you do so, if not only because you should do this on a regular basis as part of maintenence.

im changing the fuel filter tonite i got told it could be the fuel filter being blocked let u guys no if anything changes

will solve the problem if i put after martket ecu in??

coz im car will be getting on monday??

Yes, until you munch the pistons (unless you retune). Again, check for ECU error codes. If its going in to limp home (rich and retard) mode, its a pretty good indicator of detonation which will lunch your engine. Don't just stick a new part in without first working out what the problem is.

  • 2 weeks later...

its now booked into get a diagnostic done

few more things i have noticed bout what the car is doing

for about 2 weeks it wouldnt boost above 10psi and felt sluggish

few days ago it stopped, and boosted normally and every thing.......same weather.

today i was driving to work hit a hill was in 4th boost was on 14psi.......all of a sudden it just dropped back to 10psi........car still runs smooth....

i have noticed that it does it more if i am going up hills........

so i guess i have to wait 7 days till the diagnostic is done, then i will know exactly wtf is goin on

    • I've got 60L of e85 in there at the moment
    • Don't forget to make sure the tank is full to the brim before you try to replace the fuel pump too, that is an essential step.
    • No, 260RS/4wd stagea is 33 GTR/GTS4 double wishbone all round, not struts. The 2wd cars are confusingly strut front. At there rear there is one balljoint at the outer end of the lower control arm. If you have HICAS (my Stagea doesn't, but I think 260RS did, there will be a balljoint of sorts where the HICAS arm attaches to the rear of the hub At the front, there are ball joints either end of the lower control arm, plus the tie rod end for the steering arm
    • So, 2 months later, I just couldn't see any way to be happy with that tank setup. Basically the baffle area is too big and too leaky, the sender was miles off and the no low fuel light thing really bugs me. Other than the fact the fuel hat could safely supply enough power to the pump, it was worse than factory. Biggest thing that bugged me is it would still run out of fuel in medium-high g corners from about 1/4 tank down which is annoying when you are trying to have a zoom, not to mention potentially engine killing if it gets just the right amount of lean-ness....and we've got a few of those corners in our round trip to town (well, bunnings...) So, credit to Frenchy's, they have put together a much better designed setup with what is effectively an in tank surge setup.   As it happens the actual hat is the same, so I switched the fittings across, re-used the single 525 pump, and added a spare pierburg lift pump that I had (must remember to replace that stock, it was a spare for the race car). The only real work to get it all done was to add a second power and earth to the hat which I did by going from a single output to double output relay (very low draw on the lift pump) and also the sender unit that clips into the factory pump holder was again way too loose (so I re-used the 2mm shims from the previous setup). Finally, I added the low fuel light sender from the factory cradle. So....I'll report back how it handles low fuel, and if the sender has any relation to actual fuel level in the tank....
    • The price isn't the issue, it's how hard my fuel pump is to remove now. I fabricated a custom bracket so my pump sits on the very bottom of the tank (I ran the tank down to 5L remaining to test it, works well). But it is a fkn NIGHTMARE to get the pump down into the tank now =/ words can't describe how much I hate fighting with the fuel pump/hanger now. The other issue is reliability, I'm driving down for WTA in a couple of months, I'd be less then impressed if I was half way to Sydney from Brisbane and my pump fails again =/ The other issue I had was my car battery was slowly failing, with low battery voltage my fuel pump couldn't keep up with what the reg was asking from it. I've replaced the battery and my fuel pressure is back to being perfect.  As for the low voltage situation that killed my previous battery, I've got a 150amp alternator sitting on my desk waiting to go in. Fingers crossed that will sort that issue.
