Here is what happened. A mate of a customer shown interest of buying the test car, welling to pay my asking price but requested for a compression test at a known workshop that few of my customers went and have sent me a number of jobs in the past. (Not chequrered tuning or any one from the SE).

The car was perfect, drove in to the work shop. They did a comp test, all came up to 170 psi. After the plugs were put in, crank and straight way there was a knocking sound in the engine. The mechanic "one of my customer" also found a missing coil pack bolt that I know it was not missing from start. I'm 90% sure some that was dropped into a spark plug hole, but the shop owner tries to convince me its a knocking sound from end bearings. LoL. With oil pressure gauge alive and sender gage disengaged, it obviously makes no sense. I'm f*ken pissed off at this point but did not wish to turn at all those familiar faces. So that was the end of it.

I'm leaning towards of doing some work on Rb20dets. After all that's the only engine that I've missed out and the project will be very challenging.

90% of people drop rb20's in the bin. So I wouldn't bother.

What I'm interested in is RB25Neo, not DET the NA ones.

Higher compression, better response, on E85 with mild boost.

Mention is to Trent, see what he says ?

couldn't you just put a bore scope in the cylinders and see the marks it would have made as well as throw the compression tester back on there and show that its no longer the 170 across the cylinders to prove they f**ked it and 'you broke it you bought it'.

?

also why didn't you do the compression test yourself in your shop?

The buyer only trust that particular workshop, no one expected this issue. The car drove perfectly to the point when it was powered up again after the comp test.

The comp tester shown very little change after, its a metal "bashing around" sound from the upper half of engine. Work shop had a broken scope that can't be used. Owner offered $3.5G to rebuild that engine, to me the rest of the car's too rough to have that sort of money spent on. Buyer how ever was happy to take the way it is with $4G discount, his offer was accepted, and I'm over with it.

I'll be looking at few more skylines this week, and hopefully be back on projects shortly.

I guess the point of bring that up is my RB25det NEO did not broke because it had excess boost at it. The failure was totally none performance related. They are excellent engines.

Don't bother with rb20s.

If you're going to draw a line under RB25 turbos, which probably isn't the worst idea, I'd concentrate on XR6 turbs or perhaps something for our retarded VG cousins.... sorry Fairlady and M35 owners.....even the designation VG sounds a little retarded....

Stao, how many rb20 hiflows and atr43ss1.5 do sell a year? I bought one of your hiflow second hand and it is a bit laggy, but if you go ahead and develop something really fast spooling for an rb20 I would be interested.

That or a direct fit rb26 solution. The only options people have are -9,-7 and -5 reallly.

-9 resonse with -7 power would kill the market with direct fit.

Wow thats totally bs stao.. i belive youv been in the business long enough to know what your talking about.. but there are plenty of people out there that arent as genuine unfortunately. On a side note im with most of the gang here i wouldnt bother with the rb20.. maybe rb30 turbos? Or some more rb26 bolt ons.. either way im happy

Name and shame that workshop. What a dog move.

yeahhh nah for the sake of the forum that can't be done. legal bills etc etc

anyway I vote twin-cam RB30's next! (please, i'm building one)

    • 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.
