I'll have some pics tomorrow probably. Going to go down (all 500 metres away speedworks are from my work) and take some pre-install photo's and trust intercooler goodness... *droool* Hey dave where can I get some of that thermo tape wrap stuff... I might wrap the pipes before they go on? and then do the dump pipe/front pipe to cat when thats done too. Might be an idea to actually wrap some tape around that pipe that goes into the manifold over the engine that seems to get damn hot.

Steve,

It makes sense, the factory one has a small air bleed (hole on the underside) people  mistake for the factory BOV not holding boost at light cruise due to it being so-called 'too lightly sprung for high boost apps'.  

There is someone with a thread about blocking the hole off on the performance section!

I got rid of my stocker BOV for a couple of reasons. For starters the 32's have a recirc pipe the plumbs back into the intake at a point which makes the standard BOV incredibly loud when fitted with a pod filter (most atmo BOV's would be quieter). Secondly, mine used to vent at very very mild throttle adjustments, you could be cruising along the freeway and even mild 5km/h increases in speed, throttle feathering and such produces a loud "PSSSSCCCHHHTTT" sound. Not to mention a horrible rushing air noise when on boost (you couldnt hear the turbo spool or even the engine over it).

It was just plain embarassing. I couldnt drive it sedately without a massive BOV noise on every gearchange. Least the TurboXs one i have now is quiet until you start changing at over 3000rpm. And you can hear the engine note and turbo spool clear as day.

Mine did the same thing, and that simple BOV mod stops that.

I found it frustrating too :D

Now it only opens when there's a decent amount of preasure difference - not 10psi+, but enough not to open at stupidly low boost.

Ok, here are some pre-install pics of the trust cooler. Its a 600x244x76mm core (tube and fin core) as you can see from the photo's its designed to use the standard intercooler pipes in the engine bay (which I think I'll replace at some stage with trust polished aluminum ones anyway). The pipe below the cooler flows from the left side to the right side and up into the engine bay, however if you went for the trust plenum I'm sure you could adapt the piping up the left side of the engine bay. Its going in next wednesday (and the cars getting a much needed service). I'll try and get some pics of it being installed (just walk down to speedworks in my lunch break) and then some more pics once its installed, looks like we'll have to trim some of the stock front spoiler to give more airflow to the cooler. Anyway... enjoy :rolleyes:

Although I have had parts shipped to work so the mrs doesnt find out :D

hahaha ... nice :rolleyes:

That cooler looks sweet man ... should be good when it goes in.

You'll have to take some after shots so we can see it :D

Yeah, will do. Looking forward to getting it in, I wont be running 0.8bar all the time but it'll sure help when I am. You gotta remember though this will be around $3k fitted all up, you gotta be thinking about whether jap stuff is really worth that much when you'd probably get a good aussie job fitted for $2k. Should be more than enough for 450-500hp, which I'll never get to... rather buy a GTR :rolleyes:

    • 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.
