You will hit limiters/cuts before you boost the turbo that high that it breaks :Oops:

Im fairly certain 14psi is the limit for all of the GTST/GTT series, altho the difference between 12psi and 14 is very little with the standard turbo.

I hit 0.95Bar on my car last nite on the freeway, didnt have any problems at all, and it pulled very hard. But ide never run that boost during the day or anywhere other than the freeway.

If your on the freeway cruising, at night, with a nice intercooler and cold inlet temps, then give 14psi a go, otherwise stick to 12psi

my 02c

Accepted practice is about 12PSI max on standard turbos, but since each turbo is slightly different, it could be more, it could be less :)

I wouldn't go for 14 personally, but I don't have deep pockets to replace something if it goes wrong..

LW.

I am running 15 psi, with a cold air box and good FMIC. My PFC is also tuned to dump a lot of fuel at those boost levels to try and keep the temps in the zaust side of the turbo down.

I think that with a good FMIC and CAB you should be able to run 14 psi if you dont cane the Sh8T out of it all day every day. 14 psi on the track would not go down to good I would think.

Mate stick to 12 - 12.5 you don't want to kill it straight after you got it. Anymore than that with the stock ECU and all sorts of funny things start happening. I had a horror day when I set my AVC-R to .95 bar and did 10 laps of Wakefield. It spat the exhaust/turbo gasket, intercooler hose and the dummy generally.

Hi Driver, R34 GTT 12 psi for 5 laps at Wakefield Park and one ceramic turbine in the cat. :spew: That's with a good intercooler (R33 GTR), good tune (not by me), oil cooler (Earls), POD with good ambient air intake (by me), standard dump with hi flow cat and 3" exhaust (HKS) and a GTR fuel pump. It wasn't being pushed super hard at the time either. I can give similar examples, the HPI R34 did the same thing and I have personally seen 3 X R33 GTST's with the similar results at supposedly "safe" boost limits.

Bottom line, I wouldn't go over 10 psi for any extended periods. :Paranoid:

If you have an intercooler (check), an air filter (check) and a full exhaust (check) then shoudlnt you be running about 11-13psi anyway? Without even touching the wastegate line.... i was on my R32 GTST, though i think they run a lightly harder spring.

Yep only on R32's, R33's and R34's (especially) don't repond as well and have softer wastegte actuator springs. :D

    • 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.
