My lifter valves are extra stuck in the underside of the bucket, the banging method definitely doesn't work, so I've tried pulling out with lockjaw plyers, but that seems to damage the black collar which holds the valve assembly in the lifter. Do I pull on the black colar, or pull on the stainless valve assembly? (which contacts/opens the inlet/exhaust valve) is there a method or a tool that doesn't smash up the lifters too much?

Cheers

Generally speaking if you're marring up a machined surface you're probably doing it wrong. Is it possible to use a small punch, rubber hammer, and a socket to tap it out?

Yes my thoughts exactly, I did see a tech on YouTube doing what you are saying, but I can't seem to find a punch small enough to fit in the top hole.. Don't want to in large it any bigger.

PS: if anyone got a couple spare lifters in NZ please let me know. 

Cheers

I have a punch set with some absolutely tiny punches, any chance you could order smaller ones? I'm not at all handy with machining though so my first reaction to most problems like this is to throw money at it.

I tried to modify my punch this morning but can't get it small enough without it degrading the structural integrity of the tool, so I'll have another look around the big smoke on Friday (couldn't find one fine enough last visit) when I'm in town, got to love rual living haha

Perhaps, if you have to have another shot at this, try using a file. Punch lays flat on a steel workbench/piece of flat bar & held there. File kept as parallel to the surface as possible and pushed across the punch. Rotate the punch a little after every stroke. Will be slow, but will eventually get there and is not quite as violent as trying to lay a really thin punch remnant up against the grinder.

Or, do what you can with the grinder, then when you get down to the limit of comfort, change over to the file.

If ever you don't get around to getting these to work, part# VL4951-P24 for a jobber set of these lifters that can still be purchased. I bought a set for 200-300$ from Tog in Australia roughly a year ago. My engine machinist is the one who recommended them. 

Cheers.

      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.
