I was advised at one point to go find a local spring works (yellow pages) and they can make up anything you need ;)

was all too hard for me though

I was going to suggest that. Pretty much any spring that fits in there without falling over will do the trick anyway. And shimming them as already suggested will raise the pressure somewhat. Its all very easy.

Lol at lending ya car. I sure as hell wouldn't. I only let the missus take it anywhere.

I don't have a problem with mates driving my car, after all it's just a car. I often take my car to the skidpan where I let my mates have a go, it's something I think everyone who has an appreciation of cars should experience. But perhaps not at 400rwhp when they are used to driving beaten up Honda Civics, etc.

On the skid pan wouldn't be as bad cos you got your eye on it and also they aren't on the road with the opportunity to see how fast it goes or something stupid.

I loaned my skyline once and it came back with 7800 rpm on the hand controller and 170 kph. Plus the clutch stunk and I'm sure that's why it is slipping now. I loaned my commodore once as well and the guy got a speeding ticket and ripped the front bumper off on a kerb and blew a hole in the radiator which only happened at the time from revving the crap out of it.

You say its just a car but for me it is months of work and saving. If someone really appreciates a car they can work their arse off and save their money and get their own like most people do. But hey that's just me biggrin.gif

Yeh I don't just approach people on the street and hand them the keys lol :P I have a close group of friends, would trust them with far more than my car. They could easily get their own, but it's just not something they want. They enjoy driving it but they see the headaches I have with it sometimes (like the hot start issue) and it just isn't for them. Or they have a different taste in cars, eg my mate has a '78 Escort that he is building. We all have our own tastes, mine just happens to be set up for track work :P

Anyway, didn't mean to go so off topic whistling.gif

I hear ya. It's good to have mates you can trust like that. I've only been in perth for ten months so I don't know many people here. On topic now, why don't you try putting some big washers under your 7 psi spring and seeing how much it raises the boost by. If your car isn't set up for the gate yet we can try it out on my car sometime.

on this topic, does anyone know if the tomei 270 8.8mm lift cams would be okay for a stock rb25 hydro and stock springs?

This is an external wastegate thread, were discussing spring pressure in the gate and target boost.

Your probably looking for another thread, however I think the duration has nothing to do with how well it will work as its more the lift. IMHO the stock springs are shit to begin with, I would ditch them in a mad hurry.

or better yet lets just ditch the whole engine for one with a toyota badge...right?

Hanaldo: speaking with Sean from Allstar I was told to downgrade my spring, had a 7 and 14 in my 48 progate to just the 14 and use my avcr to run what ever high boost, aiming for 25psi, reason being the ecu can pull boost out if something is overheating or going wrong,

I was under the impression of getting the spring pressure as close to the target boost as possible too,

it depends on your setup, with internal gate and an actuator getting one close to your target boost is more important than with external gate as with external you can use both ports to hold the gate shut until a few psi before your target boost.

i say see how you go with your current spring and if its not enough you can always change it later.

ive got some Turbosmart wastegate springs laying around is interested in them, one has yellow paint (largest), one has red (medium) and another i think has orange (small) paint sprayed on it

im not sure what psi they are, they have been sitting in my room for about 4 years and have some surface rust on them but nothing major

Haha well those sound like they are from a Pro-Gate or Power-Gate, so they wouldn't fit my application. The red one might fit the Comp-Gate, is it red and brown or red and black? In case you're interested, the yellow one would be a 14psi middle spring, and the red one would be either an 11psi middle spring or a 12psi outer spring. If the red one is smaller than the yellow one then it's probably from a gate like mine.

I saw a spring at work today which looks like it would fit. The bloke said I can have it soon when he replaces it with a new one soon. It is very hard to compress by hand. I succeeded in compressing it about 3mm. I'm keen to try it. Just by the feel of it I'd say it is good for 20 psi or more by itself

      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.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      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

      Spotted on the street....

      By Rezz · Posted

      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.
