hey all,

just needed ur feedback on this...

i recently fitted a new clutch to my r32-gts4. since then i have had countless problems with my 4wd and clutch. i first thort that i was fitted with a dodgy clutch as after a week i was having problems getting it into 1st or reverse -- so i took it back to my mechanic. this apparently was caused by the slave/master cylinder needing to be replaced.

the car was still slipping after this but for some reason i doesnt seem like its the clutch playing up... it seems to be caused by the diff. was hoping to get some feedback on the atessa system having this same or similar problem.. do you know if a faulty diff / 4wd system could case my car to slip its gears? i guess im just puzzled as i thort rplacing the clutch would fix the slipping problem, but obviously it hasnt...

ur help with this would be very much appreciated.. so thanks in advance.

mario

hi, just a quick question.

Did they disconnect the hoses from the transfer box?

your 4wd system may need bleeding (the resoivoir is in the boot on rhs, check the level when ignition is on as pump primes the pressure in the pipe and fluid level drops) - it is easy to do, just check the gtr manual. Basically involves using the attessa pump to pump fluid thru to transfer box to build up pressure and bleed out air bubbles.

also check the fluid in the transfer case, the actual fluid that lubricates the clutch packs that transfer power to the front driveshaft and then to the front wheels. there are two filler points on side of the gearbox, one is for gearbox oil - eg. castrol vmx 80 from memory and the other for transfer box. on level surface the oil should be level with the bottom edge of filler hole, use finger to check, I think from memory you can use the a 1/2 inch power bar to fit into filler bolt to undo it.

depending on the power you have ( i.e. lots above std) or how hard you are launching if the transfer is not working properly then you may actually be spinning your new clutch with all the power being transmitted to the rear wheels and none going to the front wheels as it was designed to be.

I'm not sure about LSD'd but i dont think a worn lsd will feel like a slipping clutch... maybe someone else can provide an answer.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      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

      Spotted on the street....

      By Rezz · Posted

      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.
