If anyone has the tool to do a compression test to my car and can come up to my place an give me a hand, I just dont want to drive it, in case it blows up on me or something.

Its got biblical ammounts of oil in the intercooler and pipes (blow-by) and its dropping oil pressure badly.

So, help a fellow member! , remunerations in the form of your favourite alcohol beverage, are in order. :devil:

Cheers

A long time? what's different between an rb20 and a 25? a 25 doesnt take long to do. remove crossover, coilpack cover, coils, injector crank it over.

Is it a redtop or a silvertop? ECCS or NICS?

I'm sorry I don't have the tool Richo but maybe give James from TypeX Motorsport a call:

He's a good bloke, can do anything with any engine. might be able to help you out, but naturally he doesn't work for free. If it's only the tool you need then it shouldnt cost you much.

Whats this tool we are talking about? is it like a gauge or something,

Do you need a different tool to do a Leakdown test? or the same does the job? Sorry for my noobiness the first time I have to worry about the engine on my car.

Cheers guys

you want a screw type compession gauge. Around $30-40 from any automotive store.

also id say its not piss easy, considering most cars it takes about 5-10mins for a compression test, it takes like an hr to do a compression test on a rb. take of crossover and all pipes, remove cover, remove coilpacks, test, etc, put it all back together

Richo, it's a screw in guage that you screw into where your spark plug was. Theres no point in doing it yourself if you don't know what you're doing. As Enrico says it would take you over an hour (if you didn't have help from someone who's done it before), but if someone with the knowhow can help you out it will take 20-25 mins. Leakdown test is completely different.

If you're an RAA member you can call them and ask them to do it for you, if you need a mobile service. Get a quote first as to what it would cost you, but I assume it wouldnt be cheap. about $100 or so.

Yes I know its pretty bad, maybe time for a new RB30/RB25 and new turbo to suit :) *looks at very empty wallet* :D

Mike: I was behind you getting into the city carpark today, I remember your car because of the RPM sticker on the side, it was you wasn't it?

you obviously dont work on rb's alot or lack experience. its just as fast as doing a compression test on a sr. i do both all the time.

I can't possibly see how it is just as fast to do a compression test on an RB compared to an SR. The SR you can literally be done in 10 minutes. On the RB you haven't even gotten the darn rocker cover off by then, well on a NEO anyway. POS.

I have a compression tester tool if anyone needs to borrow.

Why you taking the rocker cover off? I'm assuming you mean the valley cover, mine hasn't been on for the last 2 years. ;) And NEOs well they've got that lovely plastic turtle shell too.

Also when does time equate to difficulty, I never said it was necessarily quick, who cares if it takes him an hour or even 2? This isn't a WRC service stop.

lol!

Mitsu RalliArt team: ok boys, we got broken rear suspension, engines running rich, air intake filled with leaves, radiator is ~ 80% clogged and we have 3 inch tread missing from rear right tyre... and we got 37 minutes to fix to the next stage... lets get to it!....

Rico: Ok... compression test... want it done in under 25 minutes... neighbours is on at 6:30pm...

Guess which one gets everythin done within half an hour first?

jks :P

Mike: I was behind you getting into the city carpark today, I remember your car because of the RPM sticker on the side, it was you wasn't it?

Yep that was me!!

my rpmlounge.com.au stickers do me proudly :P

Also I would help out but a) I don't like doing anything to anyone elses engine, because i dont want to be responsible for any f**kups.

and b) you said you need it done urgently and I'm full on for the next few weeks. I don't have any spare time I'm sorry! (I write on the boards when im at work)

Its all good mate. no worries. One thing though, can something actually go wrong while doing this compression test?, just want to be aware of possible risks, and see if I can avoid them.

So the Rocker covers stay? just need to get the valley cover off, is that right? then get the coilpacks and

coils out to expose the spark plugs and finally remove them, yeah? Shit I am so useless. hahaha

    • 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.
