4340 is perhaps the highest grade high tensile steel that most machine shops can machine!!! THe japanese ones that are below 5 kgs are a totally different kettle of fish they are billet cast then machined (very expensive)... Also all you guys wanting to go below 5 kg have you thought of the effect on MAIN bearingS when doing this and not haveing the crank balanced; as you would in a rebuild.... Word of warning!! Going to light would be detramentle...

free bump!!!they sound good pity i have a tripple plate!!

nice price on the flywheel.

The comment about going below 5kg on a balanced flywheel causing any kind of damage to bearings is rubbish however. You should retract the statement for fear of scare mongering for business, a tactic I'm sure you are not advocating.

I'd like to point out that 6kg odd is still alot lighter than factory stock and for those who don't have $500+ to spend on a lighter unit it offers a cheap but, very significant performance increase.

the flywheels are CNC machined but are they also balanced at a significant rpm?

If you can't get 10 people, are we still able to get them even if its a bit more?

Ok

We can buy 6 now for $375 each at the same price as before

The group buy will remain open to try and sell the other 4.

The company is getting 20 made at the moment and they will be ready in 2 weeks

I will PM all people who wanted one and arrange payment once they are ready to ship.

Sky30: It depends on who you listen to. From my understanding, after fitting the flywheel the following is true:

- Torque will decrease, thanks to less inertia , due to less mass on the moving flywheel.

- The engine will rev faster, thus generating exhaust gas more quickly, thus spooling up the turbo faster. (This is faster in time, not faster as in lower rpm point) Unknown exactly how faster it'll rev... depends on load and enviroment, etc.

Ive been Reading abit about these, apparently its like dropping the weight by about 100kg in first gear, so you could imagine the accelaration. It takes less effort to run. The motor will spin freer, but noticeably idle a little rougher if you go too light.

Theres a couple of good reads on the net on these. Do a search!!

They're a wee bit of a trade off... lose a bit of torque down low, but who the hell cares because you're into the meaty power/torque zones faster, so it's all good. :)

If you really care about torque (as we all really should), do a 3L conversion or put some cams in.

    • 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. 
    • 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.
