I used Subaru upper engine cleaner in my Skyline a few times, it is hard to start if you dump too much into the engine at a time but it clears after running the car for a minute or so. Neighbours love the smoke show

As above, more information is needed or at the very least a better mechanic

Those cans just seem like an expensive way to make smoke. I know Subaru mechanics use them, but Subaru is the one selling them also. Seems like a better idea to not pump so much shit into the intake like exhaust gas recirc and oil vapour.

Nulon foaming air intake cleaner.

Followed exact instructions, well up to the first point of starting the engine. Have been told there could be deposits still in the system so take it for a thrash but if that is the case why does it run ok cold then when the engine warms up it chokes up under load.

Nulon foaming air intake cleaner.

Followed exact instructions, well up to the first point of starting the engine. Have been told there could be deposits still in the system so take it for a thrash but if that is the case why does it run ok cold then when the engine warms up it chokes up under load.

What were you cleaning?

Shake the can before use, warm up the engine to normal operating temperature and for best results follow through each of the following steps.

1) Throttle plate cleaning:

Turn off engine and disconnect air intake duct from throttle body. Spray sparingly onto the throttle plate, wipe throttle body gently to remove excess liquid. Reconnect the air intake duct to the throttle body.

2) Inlet manifold cleaning:

Disconnect a vacuum hose from the inlet manifold and start the engine. With the engine running at fast idle, spray approximately half of the can through the vacuum line using the spray tube supplied. Then turn OFF the engine and leave to soak for 5 minutes.

If spark plugs are difficult to remove proceed to Step 4:

3) Piston crown cleaning:

While the engine is still turned off, remove all spark plugs. Spray a 2 second burst into each spark plug hole. Leave the engine to stand for 5 minutes. NOTE: Before reinstalling the spark plugs, cover up the spark plug holes with clean unused paper or cloth and crank the engine several times. Reinstall spark plugs.

4) Final cleaning:

Start the engine and disconnect a vacuum hose from the inlet manifold before spraying the rest of the can into the vacuum line while revving the engine. Reinstall the vacuum line and keep the engine running at fast idle until all the remaining cleaner is purged from the exhaust system.

This treatment is recommended for every scheduled service.

      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.

      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.
