Hey guys, i had enough of my car and need your help please...pleasee!

(sorry for starting a new thread but i had to, my car pissed me off so much last night)

:(:(:(

I bought a Skyline gts-t r33 ser II about 3 months ago and am not that familiar with turbo cars so i thought id ask some of you guys that have had one for a while, so all help is really aappreciated.

Mods on it:

Cat back exaust-(getting rest delivered soon i hope, waiting)

K&N Filter

Tubotech manual boost controller set to 11psi

Apexi cooler

story is: i used to have problems with misfiring until i gapped my plugs to .65mm. The car did start to run better but at times, like last night, car would misfire, cut out totally as if ive briefly let go of accelerator all together and have flat spots all over. car would hit full boost straight away but wouldnt pull, and i would feel it pull propely from maybe 4000 to 4500rpm, and it would go flat again and pull hard around 6500 to 7000rpm.

I dont want to waste money on unnecessary mods but whatever i need to buy i will. Im not going for huge power just decent.

Problem? Im not sure what i should upgrade (apart from front+dump pipe) that could help me overcome this problem. Most of the times when im by my self, car runs not too bad, but with a bit of load, forget it.

Solution-Can you guys suggest what you think could be and what would be the best was to fix it and also what upgrades i need.

Please only reply if you want to help. Really appreciated.

Plugs @ .65 = coil packs.

For your mods you should be able to run 1.0 on the plugs without a problem.

Also sounds like the stock ECU having a fit.

Back the boost off to 9psi (once you fix the coil packs) and i bet all problems go away

standard stuff really

UPDATE: Okay ran the car on 11psi and it seemed fine again. So my biggest issues come when i have load in the car-2 mates. Happend before and last night it happend again. Im going mechanics wednesday but i want to get some more mods suggestions, much apreciated.

back it off to 7psi even to where the ecu's range is. I'd reccomend getting somthing that u can tune/get tuned, even if u get an apexi afc/safc, power fc, nistune. something like that

mine was weird before i got my power fc. Upped the boost to 12psi and it hit 4500 and just stuttered, threw spitfires at it with .8mm plugs, still did it. Backed the boost off to abot 8 and it went fine

id say itll be ecu related.... but may just be ur coilpacks

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
