Ok, small update. I spoke to my friend who is an engine builder about the lifters. He can't be sure until he has a look over the head, but he suggested either poor maintenance (lack of oil changes), abuse to the engine (starting engine and not allowing it to warm up) or possibly overheating of the engine could have caused the exhaust lifters too look as they are.

Today i decided to pull the bottom end down. I removed all the pistons and the crank. And needless to say, all the bearings are worn and will have to be replaced at the minimum. It doesn't look like they have starved of oil.

My conclusion is its had a very poor service life. Possibly had its first service far too late and may have only had one other service. I know it has been service once here in Australia, as it had a bursons oil filter on it. I would say its also been started, thrown in gear and driven. As thats what most people do;, start > throw in gear > throttle > BAM, heaps of engine wear. Given that most engine wear is caused on start up/warm up. But unfortunately the average person doesn't care/know. i think this is where this engine has received all its damage from.

I'm very very pissed off and frustrated to say the least. This was meant to be an engine to get my car running again until i've finished building my RB26. This is another really annoying set back.

I'm not sure where to go from here. Do i replace all the bearings and rings and set it back to Nissan tolerances. Or for a little bit more money i could put some CP forgies in it, then you might as well put arp bolts in the rods, but for a bit more you could just buy forged rods anyway. Now the crank is out i should get a crank collar fitted and have the crank grub screwed. It just snow balls out of control. Where the hell do i draw the line, a line that i'll be happy with knowing the engine is going to run happily for a decent amount of time to come.

Unfortunately today has got me really questioning myself why the hell i'm into cars, wasting so much money and time and every time i eventually get the damn thing going again, it just breaks something else. Really frustrated and over it! sad.gif end rant.

if its just a temporary motor throw some new rings and bearings at it and drop it back in. provided you can do it yourself it shouldnt set you back any more than $500 for everything. if you cant do the bottom end find someone local on here who can and offer lots of beer.

i think incorrect or too thick an oil can also cause the wear you have seen. esp on cold starts where the oil is too thick to flow between the bucket and head properly.

Simon, Matt Millard also suggested this as another point of wear.

Nissan specify 7.5W30 factory which is pretty thin.

I can change rings/hone bores, change bearings myself.

But trying to work out bearing clearances to nissan specs looks tricky.

    • 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.
