Hey dude, Talked to you today at MW, and I think as you've figured, the r33 type will fit R34 (I think). Hopefully we will cruise soon. Take it easy.

Try Nulon Injector cleaner. Are you running 98 Premium and what pressure are you running in your tires? Mileage is also dependent on driving environment. eg. City Vs Highway. Might as well clean your air filter and plugs while you are at it mate. Cheers. Sam.

Cheers mate. Might get one this weekend let you know how I go. Sam.

Hi mate, No fuel cut issues with the car at the moment. I think the ecu has been remapped and wiring loom has been modified - posted a thread a while back 'What the hell is this?!'. As per running the stock pump, which I think is going to go soon, I am anticipating a decrease in air: fuel ratio which I think can be resolved using an SAFC to moderately tune the engine due to the increase in pressure with the new pump, due to the fact the car was remapped with a dodgy pump. How much do the bosch's go for? - I am looking for a direct in-tank replacement. Thanks. Sam.

Appreciate all the feedback guys. Thanks.

I get the weird sounds when I am starting my car, and the pump is priming; but - I also getting a raising electronic sound from the pump when slightly lifting the rpm above idle. Looks like it's time for a new pump. Where can I find these bosch pumps for a decent price you mention trel? And what do you mean about 'modifications' with the Walbro - mods to the pump itself or engine wise?. I here the Walbro's are made to operate at 15v? - Does anyone know if the flow will be fine at 12v or does the voltage need to be raised? Noob question = How can my car get tuned with stock ECU and uprated fuel pump? From what I'm thinking it can't be done without an aftermarket ECU (eg.Power FC) - Will an SAFC suffice? Thanks everyone. Sam.

yeh, tried that mate. All the 'experts' keep telling me I need ADR approved rails and mounts. When looking at the rails and mounts themselves, I have contacted various online sellers with them confirming that they may not even come ADR approved. I thought the guy that approving the adapter bracket (see above) for the seat, should be able to do the mount/rails at the same time ? I'll keep looking into it though.

Think I might go with something like a Tomei Fuel Pump - 255L/H for skyline. Do I need a tune after the new pump is installed if using the same regulator? Thanks.

Come on guys - someone must know something surely! Anyone out there!

Hi, Ever since I have had my car (4 months), I have noticed it behaves differently as the level of the tank changes. Around half way, it seems to run rich (sluggish) and goes through the fuel FAST. When almost full and getting low, the car seems to run leaner and respond well to boost and spools up quickly, responsive and alive? It's an r33 skyline S1 by the way. What could it be?

Hygroscopic. Gotta love physics and chem from highschool. lol.

I regards to the oil pressure I happen to know someone with a black S2 R33. His oil pressure is quite low and at idle can stall. The car has something like 90XXX km's or so on it and seems to be in farely good nic. How long since your last oil change? Oil gradually becomes thinner as time goes on as you most probably know, which can result in a gradual decrease in pressure. Get some new oil in there I plan on gapping my plugs to .8mm sometime today, not running extremely high boost, but my idle is a little rough. The oil change will probably not fix your problems, but it can play a factor in an old engine I think, and will help to rule the whole pressure thing out if your leaning that way. If you have recently changed the oil or it is within 5000km's, then don't bother. I would definately put some money on the fuel filter though. I used to get missing and it seems to emphasise the effect with an old filter (going to change again soon, being a bit tight tho because I just bought a new socket set). From what you have said, the fuel pump. etc. is new, so maybe there is restriction possibly caused by the filter - although not neccessarily, because the problem is cold start related, which can lead to questions relating to the age of the engine and the wear. etc. Do some good researching on the rb's and find out what might be problematic in older engines which is all I can say. Could be time for new coilpacks. Investigate the issue further, not really too sure as to what it might be, maybe try PM'ing some of the more experienced members or search for symptoms on the site. Look at the more specific details which may help you cut the variables down on what could be causing the problem, specific sounds.etc. Hope you can find the problem and fix it mate. If you have any clues on bucket seats - check my thread ha ha. Sam.

How many km's does your R32 have on it? I know this is a long shot, but you could be losing compression as the worst scenario case. 500 seems a bit steep mate, you can start looking at buying new injectors at that price. Maybe change the plugs and have a look at the coilpacks. What's your oil pressure like? and level? Just a bit of looking around, hard to know what it could be, but by the sounds of it you must think it is electronic taking it to an auto electrician. Try a local mechanic or a reputable mechanic you can trust (if you have one) I haven't got one yet... Do you work on your car much? Maybe start tinkering and gain some general knowledge in how your car goes (sry to sound blunt) can help in the diagnostic stages. Hope that helps Sam.

Sounds like you are new to skylines as well Maybe go for the GTT, start off small, it obvious from what I have heard GTR's can get expensive The GTT only has one turbo and one would think less on the pocket-emptying side than a GTR can be, although I have never owned one myself, it is understandable The rb25's seem to go well, see how you go. Goodluck.

Anyone? 14 views, come on - surely someone knows something... Is it even necessary to have ADR approved rails? Please guys
