I have an R32GTS-T 93 model and am having problems.

Mods Are:

Greddy FMIC Vspl

Bosch 040 Fuel Pump

Blitz DSBC (Switched off)

Plugs: NGK Iridi's 6's i think at 0.8mm gap (the usual people get when boost has been raised)

3" turbo back exhaust

Just been full serviced (oil coolant filters plugsetc etc)

Thre are a few other things but just put the main ignition related ones

Anyway, Ill be driving along and ill lift off the accelerator for whatever reeason, go to put my foot back on the accelerator(not hard or anything) and the car seems to hesitate to fire, as if its get a nasty misfire, then coming back good until next time i take my foot off the accelerator and od the same again. Anotehr time i had clutched the engine as i was rolling to a stop when i first noticed this, and the car stalled out, as well as happening again another time. If i restart it its all fine to start but still does teh hesitation thing all over.

Now if i go for WOT, then the car is fine, it fires as it should as far as i can tell. Probably backfires a little more than it usually did but nothing excessive. I was wondering whether people had many ideas? its doesnt seem to be heat related (coilpacks) but u can never be too sure.

Im leaning towards coilpacks but i dont wish to fork out for a full new set just to find that this doesnt fix the problem. Another thing is that when i got the fuel pump installed, i noticed after that the lines (inlet in outlet of the tank) seemed a little "aged".

Any questions or possible solutions will be appreciated.

Cheers David

Standard ECU, boost is at 9-10PSI so i dont think it would be R & R..but hey it could be...Yeh i think ill look in to getting her dyno'd.

Is there any other thoughts on what it may be??? Feel free to PM if need.

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
