Hi,

Looking for some help with cams... I've just bolted up a GT3076 A/R 0.6 with internal gate to my RB25 series 1 and I have a pair of Tomei Poncams 256 degree 8.5mm lift I would like to drop in. I'm not looking to get any real power gains from them, but just to move the powerband round, for more response and and earlier spool up, would these cams be adequate for the job? The cams came with the option VCT retained, what is this about and is there any tutorials or DIY's on instalment of these cams?

The job itself is fairly straight forward if you have good mechanical skills. Download the RB25 engine manual and there is a section that covers cam swaps. Just follow that.

I see your located in Townsville.. Any good tuners you could recommend?

I fit Tomei Type-B's to my 26 a little while ago.

Some things you might like to know...despite what others might say, I got the motor to TDC and zip tied the cam gears to the belt, the gears are a little tricky to get back on doing it this way when reassembling but its def do-able. Removing and reinstalling the cams is easy enough, just unbolt the caps in the factory sequence and do the same when refitting, be very careful when retorqueing the cam cap bolts and use a small 1/4 Drive inch/lb torque wrench or similar, they are piddly little 6mm bolts and are very easy to over torque and snap!...You will likely need to replace the cam seals, its worth doing if they havent been done even if you get them off without damaging them at all. Use sufficient assembly lube on the cam lobes, lifters etc.

If youre not at all mechanically minded, I wouldnt take this on yourself, you'll need a timing light etc once youre done to check timing. Good luck.

Yeah I would recomend winding it back abit from top dead centre that way theres no chance of the valves hitting cylinder 1 or 6 as they can be abit tricky to keep straight when putting the first few cam brackets on. Doing the springs would be a good idea to save you from having to open it up again.

    • 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.
