Turbo Dave

Not sure if it's the same a GTR but get a 14mm socket and extension and take the whole cradle out. it comes off 3 at a time. Be sure to remove the loom and cover first of course.

315rwkw

Cheers I will have a look tomorrow and if I have no luck I will contact my tuner and get it sorted.

Sorry only had a few mins of service before. 1995 R33GTR Has a link G4 ecu, Older style N1 turbos, 650cc injectors, 3.5" exhaust running 16psi.

Got my car tuned a week or so ago and have only driven around town until today, just arrived in Sydney and it running like crap! stayed off boost as much as possible on the way up but still averaged 13.9Lper 100 which I reckon is a bit steep! Light load driving is good but but it missfires and pumps soot out the back under high load. Can it go out of tune? Or has my highway tune fouled the plugs?

Oil pressure in my GTR sits lower than my GTS-T did under normal driving, still goes up the top when cold and when up the top of the rev range(5000+). When Driving at 2900RPM on the highway mine sits just under the No.4 Mark. Not sure if this is normal for GTR's or maybe has the same sort of principal as the N1 water pump that doesn't move alot of water at low speeds as it's meant for lower drag in high RPM application's. Not sure if my car has a stock Oil Pump or of it's an upgraded unit that has a similar theory behind it. I use Motul 300V Competition 15/50.

I do get that feeling also, I drive a truck for a living... 62tonne B-Double not exactly the fastest accelerating machine! GTR feels like a Go-Kart after 12hrs driving. I spend a few hours a day trolling threads and reading different results from peoples setups. I'm set on getting to the 400kw mark when the time for upgrade comes so instead of have a toy in garage, I have a "Silly Toy"

Locaton slows me down a bit as I don't want to get it rebuilt in my own town. And I like being married so I tend to tell her the truth.... Most of the time anyway!! Haven't done comp tests yet might do it next time I do plugs. What numbers should it read???

Oh man! Almost perfect timing on the -5's. Some groveling to be done me thinks!!

Had a Heart Failure today when replacing my plugs, No.6 was firm the whole way out and didn't tighten up. Thought it was going to be an engine out job but found a place in town that Helicoiled it in the car. That would have been a great excuse for the Missus to accept a rebuild...LOL!!

I'm currently running 315rwkw with the stock airbox and K&N Panel.

It might have been the older style Turbo's running out of puff at higher revs then. tuner said that when he went for more boost it the boost was getting wavy. Boost dropped off at 7000 and you could see it fall back on the rollers a bit. as seen here... Plan to date: Check engine specs, custom intake, -5's and fuel system to match and life will be good. I've seen a few vids when GTR's drive past bikes and just gets me wanting, but I still have to be a bit realistic and keep it drivable and not just a top end machine as it will do some interstate drives on occasions.

Not sure if it's built as yet, has had a tune but we are treating it as a stock motor until proven otherwise. Running 17psi daily but anymore and the stock airbox struggles up top. I'm going to address this once the -5's come along. Had an SS a few years back but is was quite dull really. And no matter how much money you spend on getting it going it will always be a "Commodore".

Yeah I know but I can't fit the family on a Hayabusa anymore!!

From what I can gather my current RB26 is a forged engine, so if I can confirm this when the time comes for some -5's it might be a cheap (sorta) upgrade. Would a Tomei pump and 650cc squirters runs the -5's to the end on the RB26? If it's as simple as a turbo upgrade and new map sensor I think this will be happening sooner rather than later, 400+ is calling my name??
