Might sound like like a silly question but without a detonation or knock sensor how can you tell if your engine is detonating?

Curious because not sure how much a standard internal RB20 can take before breaking conrods n big ends

everyone has a different description.

It can sound like small stones on a tin roof, or stones kicking up under the guards.

To tell - ask your tuner.

Stock RB20 innards will easily run 260rwkw day in day out.

Know of any videos of engine detonation sound? cant find any on youtube My car has these mods atm -

HKS 2530 Turbo

GTR Injectors

GTR Ballast Resistor Pack

Bosch 040 Intank Fuel Pump

Hybrid Front Mount

Z32 AFM

Turbo Back 3" Exhaust

5 Puck Brass Button Clutch

Car needs tune atm the guy i bought it off had it tuned by PITS in Qld anyone know who they are?

Apparently got 220RWKW at 16PSI

I need to get it tuned, how much boost is this setup capable of?

How long is a piece of string?

Twice the distance from the middle to the end. :)

I always thought detonation sounded like an olllld diesel hehe. Its not a nice sound, so if it does it, youl know.

Try taking off up a steep hill in 2nd. tickticktick

If detonation sounds that bad then ive not noticed it yet thank god. I dont have a tuner yet I live in Nothern NSW On the beach there isnt any good tuner shops here i was thinking of taking it to mercury motorsport for a nistune until i can save for a Power FC or whatever

yeh matt spry is claimed one of the best in QLD so u should be fine unless things have been changed since the tune.. are u askin about the sound cause u can hear it or your just worried? doesnt it feel fast?

just tryin to figure out the reason of the question

Sounds like good news to me! The only problem with the car is its running pretty rich (it chews the fuel) and black soot covers the rear bar lol Other than that is the broken exhaust manifold stud which im about to try fix which i guess caused a bit of surge hard on the gas in 3rd or 4th

About detonation was just curious as to how much boost I could run with this setup, its pretty happy on 14psi which is fairly close to 1 bar right? (my boost guage is in BAR not psi) would 18 psi be ok you think? the guy i bought it off said 18psi is pretty fun haha

    • 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.
