Ok cheers heaps, I havent been giving it a hard time as I know all about blowing un tuned engines. I am getting it scanned and looked at this arvo, so hopefully we can get a Nistune chip in it ASAP and get it running right with a bit more power!

YES it is sort of stalling at higher revs when I boost it over about 5000 rpm, sort of like fuel cut. Im hoping it is something simple as I am loving driving the skyline, coming from a boosted STI, it is sooooo much smoother. Thanks guys, much help!

Yeah the high pressure fuel I cant explain. But I have a feeling the owner before me had it boosted to accomodate for the mods. I am yet to get a scan tool onto it, but thats my next step. Saving for a Nistune as we speak. I am weighing up seeing DVS or Powertune - both reputable r34 tuners. AAC valve? Ill have to suss that out. Thanks for the tip!

Hello all. I purchased a 2000 model r34 GTT and since buying it, have noticed that sometimes the car will be quite difficult to start. It is a little hard to explain but I'll give it a go. When I start the car in the morning, the engine will start straight away. Sometimes I will turn the key and it will keep turning the engine for maybe 10 or more seconds before finally kicking over and idling very low to begin with, but catching the proper revs and the car will run fine. Some days I can start the car fine, turn it off, start it again and will be perfect. Other times it will start fine, then take ages later on in the day. I replaced the fuel pump from the standard unit to a Deatchworks DW300, and also did the direct wiring mod - and absolutely no change whatsoever. Mods include a HKS GT-RS turbo, Greddy front mount, Apexi pod filter, some kind of FPR, Fujitsubo titanium exhaust and standard ECU (no tune). I have taken the car to a mechanic and he checked all electronics, said that they were fine. The fuel pressure was very very high though... I'm assuming the fuel pressure reg has been adjusted as there is no electronic tune?? Any suggestions? Cheers. Sam

I have a fishtank, with all accessories. Real decent setup. But I'm in Coffs Harbour unless you're going to be up here anytime soon? Or can get to Sydney next weekend? Haha.

Yep, I read that over and over again, but then realised that Im still not going to low enough inside the tank for the pump to work... I purchased a DW300 pump from Prospeed Racing last night and hoping it arrives throughout the week so I can get it in and the car back on the road!

Hi guys, new to the forum but in need of some serious help. I recently bought a 2000 ER34 GTT and have had some starting issues in the 2 weeks ive had it. The car will start in the mornings when cold first time everytime, with the fuel pump priming as normal, but sometime (especially once it warms up) the car will crank for maybe 10 seconds and only just start. So I did the wiring mod with relay and fuse directly to the battery, and it feels and sounds like it is running slightly better. But, today I bought a new fuel pump - Bosch 040. Took the standard fuel pump out as normal, but when I compared the 2 fuel pumps they are completely different? There is no where for the sock to go, the pump wont sit in the bracket, and the connections are all different?? I have done A LOT of research and cant come across anything to help me do the swap. Has anyone done this exact mod to their GTT? Any help would be much appreciated. Cheers for any advice, I will introduce myself properly with pics asap. Sam
