hey all, just went to put a malpassi on my 32 with an rb20 but noticed there is, or appears to be 2 fuel regs. 1 in the normal place like on 33s etc. but another on the other end of the fuel rale... is that another reg? if so how do i go about getting around it and putting the malpassi on? i am sure there are a few that have done this before. .. also does any1 know what the standard fuel pressure us? thanks 4 the help. leigh. i can post pics if needed.

i dont know about this second fuel reg that you say you have. but its easy use an adapter plate to replace existing standard fuel reg at the end of the fuel rail.

easy done then mount in your Rising rate fuel reg and mount

pfffft.... yes i do need one!!!

here are some picks that sorta show where the second one is..... u can c it if you follow the fuel rale towards the rear of the car. i circled where it is. under the plenum.

ok, i have:

- trust TDO5/O6 round 450-470 hp?? unsure

- turbosmart 45mm pro external gate

- cooler

- safc

- bosch 040

- 3 1/4 inch exhaust from turbo with no cat.

- think thats bout it

i have done all the work my self from bolting the turbo on and making the cooler pipes, etc. the car is running fairly lean atm.. and as i dont have enough $$$ for larger injectors or management. i am going for the cheaper alternative of a fuel reg and tuning it with the safc and reg, and maybe backing off the timing if need be, but doubt it.. i have already purchased the reg so i might as well put it on. if u have any other sugggestions please give... i just want the car to be safe. me and a mate will be dyno tuning it once we have the malpassi on. i have seen in the rb20 turbo upgrade results that a few people have regs so any help would be good. i wanna get this on the dyno!!!!

thanks leigh.

ive see you a number of times... do you have a REALLY loud screamer pipe? the other day you were next to me and it didnt even seem like u dropped a gear and you were sideways for f***en ages lol i was in the white VLT...

also i dont see why all you guys are asking him weather he needs a malpassi or he should get a new fuel pump for? he is asking how to put it on not should he put it on.... but just to answer your comments this 32 is f**ken nutz i run consitant 12.8's and he was pulling away from me... i think he could use it...

sorry no help but yeh some rude people on here..unless they mount to the end they look a bit messy not that makes a deal so ive ordered one from japan that bolts on the end of the rail...its a bit weird that there is a regulator of sum sort up the back..

post up how you go when done

goodluck

haha yeah that was me... i remember.... u have a big bresciani sticker on da back window... hahaha

i have no ploblem having to fabricate a new adaptor where the old fuel reg is, i can do that at work... the issue i have here is if what i showed in the pick is another fuel reg. and what i have to do to get around it (if i need to get around it)... thanks leigh

Its probably because its as Craved and i thought... he is trying to nab extra power, but there could be other sinister reasons for the fuel issue.

The reg really wont give you much more of a higher ceiling in terms of fuel flow and what you can get out of it safely. Its that simple really.

Has the fuel pump been wired up correctly?

It is getting the correct voltage?

How lean is lean?

Are all the injectors in good condition?

There are a number of things to check if your leaning out IMO rather that buying a band aid.

Just because it sounds cool, i ran a 12.1 with a stock fuel reg, maybe i could have run an 11 if i had fuel reg...... :)

hey lwboosted...to answer your questions

a) yes it is another reg but dont worry about it, just leave it. You need to replace the front one. make an adapter and mount the reg somewhere..strut tower is nice, close and easily accessable.

b) standard fuel pressure is 38psi.. a few psi will make alot of difference. i run 42psi

Hope that helps

lol... i'll stop crying when people fix thier cars the right way :rofl:

Amen to that!!! I give it a month from installation before the motor lets go depending upon the tune. IMO Malpassi's are shit and should not be put on any turbo charged car thats running high boost levels. Its just that I dont trust a flimsy bit of silicone nomex to control fuel pressure at the pressure levels your going to be using, probably around 70 - 80psi I presume. One good thing about them is there ability to not hold pressure when the fuel pump is not running (bandaid fix for leaky injectors). The reason that standard FPR and sards are so good is that they have metal diaphrams making them impervious to pulsations through the fuel rail.

However if you still decide to persist in putting that junk on your car then leave the standard fpr where it is. The return line from the standard reg then feeds into side of the malpassi reg and the return from that then goes back to the tank. Make sure both still have a good vacumm signal. This way the majority of the pressure is held by the standard FPR.

yeah i would agree that you would be better off putting a sard in. i chose a sard for that reason..the metal diaphrams holds pressure perfectly..sell the malpassi to some n/a car owner and go get a sard...and bandaid fixes are not a good idea either..if your injectors are leaking...more pressure will just worsen that problem..so do as R31nismoid says and check pump voltages, check you fuel filter isn't blocked, check condition of clamps and injectors. I would do this even if you still put an adjustable reg in

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
