I have a top mount fuel rail with 750cc injecorts and a plenum waiting to go in Along with a hypergear atr43ss2 turbo z32 afm and a powe fc so i think i may need one when it comes to tuning in the future

From what i can tell its a ebay spec one. Currently looking for a better replacement one

Problem solved turned down the fuel pressure and now running like a dream

Stock ecu with a re map. And i have no clue it was just the way i got it when i bought it. It already had it on.

Yeah thats the plan. Havent had time to yet at work and car at home

Ive got a fuel reg on there now and its showing 105 psi on idle. F**king high i know.

So could that be the issue? The standard pump was actually handling that quite well so i never needed to check it. Until now. And now realizing how stupid high it is

i know it is i haven had it tuned since ive gotten the car. Previous owner had it tuned to that . Ive just now realized how stupid high it is. I look at it this morning and got a little bit confused.

And this is the graph of the flow rates

Ive just been doing some more reading on what could possibly be causing this problem besides it being a dud pump, ive found that pump i have may not necessarily be a high pressure and if there is any more then 60psi of pump pressure running through it it could cause it to drop in power. I had a look at my fuel reg this morning while on idle and it was showing like 105 psi so obviously under load and boost the fuel pressure is sky rocketing. So my thoughts is if i drop the fuel pressure and get the combined fuel and boost psi under 60 should it then resolve the problem?

Hahaha shifty ones. Well ill see how i go. If i can handle this company to send me a replacement pump and i get it fitted and it still does the same then i have to look deeper into the issue but if it doesnt well it was obviously the pump then. So fingers crossed

And i used the orginal sock off the standard pump because i was looking at the tiny tiny sock they supplied with the pump and basically said yeah no lol. So i put the orignal longer sock back on it

Fuel lines have been put back to orignal positions so no real issue there. And it sits in the cardle basically the same as the standard one and put the cradle back in the housing in the tank. So basically exactly how the standard one was is how the walbro is. Ive just emailed the guys i bought it off to see if they will send me a replacment one under their warranty basically to see if it is the pump or somethin else.

So if the direct power souce doesnt work then i can rule out everything else and bascially conclude the pump was a dud

Yeah its doing my head. So i guess eother put the half dead one in then when i get it tuned put the walbro back in or just dont drive it until i get it tuned lol

At the risk of sounding like a idiot im having some issues. I have a r33 gtst. Ive just recently replaced the std fuel pump with a walbro255lph and since ive installed it the car has been running like a dog. Its been splattering and just generally running like a pig lol. So i really need some help would the best bet just put the std back in until i get a tune? Or is there something else i can do in the mean time to get it running half normal again

Hey guys i know this has probably been asked before but i havent really seen the answers that i need. So i have a 1995 r33 s1.5 and my steering wheel has had the d**k lol. I want to replace it with the standard one but im finding it so hard to find one the same because mine has the airbag and its not the s2 wheel. But what i have found is this, exactly the same wheel but its off a pulsar, my question is will it fit to my car?

Hey toshi quick qoute mate R33 s1.5 Hypergear atr43ss2 turbo Fmic 750cc bosch injectors 255lph walbro fuel pump Greddy style plennum with std throttle body Z32 afm 3inch turbo back exhaust Power fc May have to get the plennum and injectors fitted

If there is can we make it a wednesday I work weekends haha

Just called armor motorsport sounds like a nice guy he quoted about 800 for the tune and about 85 a hour for any other work that needs to get done

Yeah thats true aswell. And from what I heard hitman works for haultech now. Ive got a power fc so its a fairly common ecu

Beautiful I might give them a call today and get a quote

Yeah ive heard alot about uni group. Just realised now that there not 1000kms away lol

Are they good? Its hard to find a tuner out this way that doesnt specify in v8s lol

Hey guys this has probably been done to the death but im just wondering if anyone knows of any tuners out in the pernith or surrounding areas. I will be needing a tune soon and really dont want to either crawl my car or get it towed over 100km to get to a decent tuner in the inner city. Thank
