OK Update: Cat seems fine as mentioned above. Its 3" in and out but dont know anything else about it. If anyone know any details let me know. Is that the ceramic mesh they talk about inside?

Checked the Spark Plugs and coil pack (which looked like new to be honest), all seemed fine... pic is below, can anyone tell me what condition they are in like if cars too rich/lean or probs with timing etc??

and the main thing is i am 99% sure i have found the problem!!!!!!

Turbotech boost controller locking nut has rattled loose! so... im guessing its letting the pressure out of there hence not controlling boost properly. Will confirm tomorrow after i drive it to work coz i cbf driving now.

It should of been one of the first things i checked god damn it but oh well at least i didnt have to waste $$$

so it looks like it could be the cat

it is laggy i guess but it has always been like that, under 3.5k it is useless even tho it is standard turbo

in case it is the cat, what is recommended? i hear metal cat is the go but lately a lot of people have had theirs fail

Im planning on getting a catco metal cat...so im quite interested how it failed on other ppl?

It is the same diameter as my exhaust system, however u may be right if its talkin about inside diameter

either way i dont think this is my problem as it was fine before with this cat

Take it to a dyno place and get them to load it up (the wastgate) on boost..if the readout shows a drop off of boost throughout the rev range get someone to hold the wasgate shut with there hand and do another run... if it doesnt drop boost theres your problem.

I think the Catco cats with stainless mesh are fine, "Metal cat" is a different brand and supposedly they've had some problems.

^^^ The metalcat cats have been known to collapse on themselves...the catco ones have also had a problem where the whole internal structure comes loose and causes a rattle sound...does not affect performance though unlike the metalcat one...but i have to say that my metal cat works a treat...just hope it stays in one piece....

well it got dynoes at 193rwkw (not where i got it done last time so the 10kw variation is acceptable because of weather/dyno variables etc)

boost tapers off but was assured thats normal for the stock turbo as it wont hold 14psi (not big enough housing)

a couple minor tweaks but yeh basically everything checks out, afr's were a tad lean so they increased to 11.5 or so coz of hot weather

so could just be my head playing with me

    • 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.
