my rb26/30 with a gt35r 1.06 rear jun stage one cams, 1000cc injectors, twin fuel pumps, etc made 700bhp @ the fly and 660lbs torque@ the fly that was at 1.8 bar though, so yes its possible thats on 98ron pump fuel /uk we did a run upto 2.2 bar and got almost 750bhp/700lbs torque but turbo was overspinning. went to castle donnington race curcuit on friday , open pit lane and did 80 miles on track at 2 bar all day no prbs..bernie

i want as much low - mid toqrue as possible without excessive wheelspin. im runing the .82 rear on the 3540. how much boost could i run? a friend of mine on the standard rb25 (r33) ran 26psi which i havnt seen but ppl talk to much shit these days so just wanan confirm.

ive forged the bottom and aiming for the 500hp park.. so around 370 380RWKW.....

possible with standard cams? if not how big should i go? again it is a street car so trying not to get TOOOOOO MUCH attention with the lumpy noise.

p.s max output on standard pump fuel with standard cams?

no way in the world with std cams - poncams would suit you pretty well

low-mid 300's with alot of boost

you are better off getting some headwork so you can make more power with less boost. as SK always says, boost is just a measure of restriction - the more boost you have to run, the greater the restriction in the system

cams and gears will be well under 1k. give dan from elite racing a call on 0407 111 229 - tell him shane sent you :P

yeh tru, although i always rather speak face to face.....lol

well ill keep u guys posted when i get my car back....honestly i dont know what the hell to expect......i hope the rb30 holds its reputation for delievering lol.

Have no intension on spending more money, so unless he is willing to do it for free, i have no need to speak to him :)

Spoke to two engine machinists and also an avionics engineer, that builds and repairs aircraft engines, all have stated that a pinhole in the block is almost impossible to see/find. A crack is different as it is bigger, etc., but a pin-hole would not show up on the x-rays or sonic tests.

Either way, i bought the block through my mechanic, so it is still being replaced, at no expense to me. But i will seriously consider buying the piston rings and passing the other info onto my mechanic, even though i am confident in his abilities.

Ok, I will bite..............why don't you just get the pin hole welded up in situ? Take no time at all on the hoist with a Mig.

The real question, how come it has a pin hole in the oil gallery anyway? Being oil filled, it's not gunna rust through like a water jacket.

My guess would be a crack emanating from the oil feed for the turbo or the oil return. That happens when people over tighten the fittings.

Sorry but after building over 40 RB30's, I just don't buy the random pin hole reasoning.

The repair of the hole has been lightly discussed over the phone, but i personally would feel more comfortable with the block replaced, especially for the fact that it is only going to cost me time and maybe a set of piston rings. As you have stated; i too am not convinced that a pin-hole would appear without a crack on the other side. Which still means that the machinest hadn't done his job properly, when crack testing the block.

Don't know how it happened, but i do know that it is not located near any fittings.

PS: Haven't seen my mechanic since Wednesday morning; has the sway bar been repaired and sent back? It had not arrived yet, by the time i left at 11am.

Were any pics taken of the problem?

Went 560 rwhp today on 23psi, and then started to lean out again.

Current setup is an 044 intank feeding a 044 in line - all on 98 BP fuel.

I think Ill have to go twin 044's and a surge tank to overcome this problem. Wanted to keep away from fuel pumps in the boot etc but cant see any other options now.

you could possible fit an aeromotive a1000 under the car

i was originally gonna fit mine under the car (32 gtr) but decided it would be easier to run it in the boot because of the fuel cell, and its a drag car now

    • 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.
