if i was you i'd be taking the car to somewhere else just to do a dyno power run, as if i had spent my hard earned $$$ and changed to a turbo that can take 18psi on a rb20 and then got less power than a standard rb20 at 14psi it would make me think "WTF"...

106rwkw at 5000rpm at 16psi apparently this is as much as a hotted up 5ltr HSV (cam exhaust, cold air) on his dyno.  It was run in 5th gear.

This is a crap figure so you know I am not lying.  There was no fan so the IC wasn't working (does that make sense.)

I have also had fitted a BOV that is set to 16.5psi, the turbo I got is not ceramic so it will go to 18psi.  

Does anyone have a comment on how what dyno figures really mean.....?

I wouldn't be at all happy with that power figure!! Stock FJ makes 110rkw!!! Mate of mine with an RB20 made 197rwkw with just a VG30 turbo, FMIC and exhuast, not tuned or anything..Did u end up getting another power run elsewhere or???

at the wheels a standard r32 gtst should make 115-117kws, with a 3" full exhaust that will get around 15kw extra then add a good fmic for another 10-15kw remap the ECU to run 14psi and that will leave you with 150-160rwkw

That is exactly what I thought. I should have around 220fwkw at 15-16psi with the mods I've got.

didn't get around running it on a dyno but I found a leak. I used permatek type 3 around the leak but I haven't run it hard yet. I'll repost when I eventually get around to dynoing again.

Doing it the way he did doesnt sound at all dodgy to me, much hbetter to tune it for those conditions, then you can be sure it wont expire in summer.

Intercooler is just a heat sink in any case, even without a fan it should be ok for a single run because while the car is idling before you run its not getting any heat transferred to it so it starts cool

My stock boost FJ20 made 124 in shootout mode

how does the VG30 turbo rate on an RB25? they are steel wheel/shaft right?

whats the difference in A/R to the RB25 turbo?

Im not 100% sure on the size differences compared with the RB25 turbo, i do know that u can get two types of VG30 turbo though, one's ball bearing the other is bush bearing...Most VGs are ceramic wheel whilst u may just find one or a few that are steel, they exist but are rare as...

    • 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.
