Hey I've done a little searching on the matter but haven't been able to find what I'm looking for. Anyway, my GTR is slow off the line, what sort of things do I need to add/change to give it a little more take off without having to dial up a heap of revs.

Although that is fun, its not so good on the street. The car just feels heavy off the line, should I just assume that because of the gtr's weight and the 4wd that it will always be heavy, or can this be helped in some way, like with a better flowing exhaust or something like that.

i got a lightened flywheel when i did my clutch and the ease in takeup at low revs was very noticable especially for normal day driving. it was a completely different car to drive. not sure if this what your after or if it is suited to you

wow thats interesting...I was always under the impression that lightened flywheels only helped in the higher revs..Thats the second person who reported better low end torque from the lightened flyweel mod

lighten flywheels help alot in engine response.

I know TODA do a really good flywheel...they come in many specs from mild street to outright race...So response has improved ...howabout low end pull...like take off without the big revs...better by a noticable amount right ?

GTR's will get that. The car is alittle heavy for what it is OR can be a bit lighter. Basicaly you feel the car getting "bogged".

Getting a good launch = rev the car to about 4000rpm + to get the turbos spolling and engage the clutch.

Lightweighted flywheel will help alot and twin clutch plate but I will go single Extra heavy duty.

you dont have to launch them hard to get off the line quicker, with a heavy duty single u should be able to bring it up to like 3k and then just ride it a bit off the line. Not as harsh on the various components that way compared with like an 8k dump and still reasonably swift... any1 else agree?

its kinda feeling where with the old flywheel when you just engage it bogs and doesnt want to go but with the lightened flywheel it wants to go....your expecting some lag but its just not there anymore. all normal street, carpark driving. maybe its the combination of the cushion button engaging better? mind you i did get adjustable exhaust cam and a light tune but the car is rediculously more responsive than before.

My experience with a lightened flywheel suggests it will rev faster but bog down more. I had a 240Z with a 8lb flywheel and it would rev so fast but you had to really slip the clutch to get moving. And a 240Z only weighs about 2/3 what the skyline does, of course without as much power. A lightened flywheel doesn't have as much momentum built up on the revs so there is less to transfer to the drivetrain when you want to get moving. Once moving you will feel the difference in acceleration.

I'm really curious on this too. The latest HPI Skyline special has an article on going 11 sec 1/4. It says to take your GTR to the rev limiter and hold it there, count to five and dump the clutch. Sounds like a drivetrain failure wanting to happen to me.

So do most folks here launch between 4-6 k revs? How much difference does it make on your 60 foot times if you really launch hard?

Keenly interested too. thx.

^^4000RPM is quite a bit.

1st time I was gettting use to my HKS twin plate, I accidentaly revved it and launched at 4000RPM and I was pushed back in my seat and cought up to the car which was about a car length ahead of me.

I was like "WTF! Geez! What the Hell! Then got use to it. LOL!

      gtr hood match gt/gtt front fenders?

      By JC71 · Posted

      would a r34 gtr hood line up with gt/gtt stock fenders? after latch, front bumper and hinges are swapped for gtr ones? or would the fenders be too low or high in relation to the hood surface? ( I believe seeing somewhere that gtr front fenders use some type of riser for the sides, but do not know how that relates to stock gt/gtt fenders.)

      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
