hey guys

i just did a compression test on my R32 (rb20det) 121xxx kays on the clock. i did it on a hot engine and another when the engine was cold both i did with 'WOT' also the car atm is blowing white/grey smoke at cold start and goes away when the car gets warm. im thinking its the valve stem seals and its misfireing at high rpm..

as u all know different gauges give u different readings low or high.

HOT ENGINE | COLD ENGINE

----------------------------------------------

C1 - 122 psi | C1 - 123 psi

C2 - 119 psi | C2 - 118 psi

C3 - 120 psi | C3 - 116 psi

C4 - 122 psi | C4 - 120 psi

C5 - 120 psi | C5 - 119 psi

C6 - 121 psi | C6 - 120 psi

3psi difference | 7psi difference

let me know wat u guys think...

cheers

bill

my car had very similar results when i bought it, i asked the mechanic if it was a little low and he said its fine for a car that age.

meh its been fine for 30000k's although there seems to be a ticking noise developing which i think could be the injectors or possibly the lifters....

Rb20. Punish the thing until it dies and get another one and repeat. Its loves pain.. give it more. I think you are making it bored and its coughing in the mornings from lack of exercise.

besides drunk ramblings. compression looks ok to me... maybe your guage just reads lower than others )which you know). not much difference between the cylinders.

What do you plan on doing to the car? You want some power out of it or is it just to enjoy as it is?

On another note, if it were me i'd start to put some money away for a rainy day but enjoy the car until the inevitable happens, which could be a long way away. Depends how you drive it really.

Hope this makes you feel better.

on the pwer side of things. the rb20 is pushing 225rwkw's on. but i was planing to sell it just when this started:( wats the cheapest i can change the valve stem seals for?

i reckon it would be cheaper to just buy another rb20.... you can get them off ebay for $100 lol

    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy. 
    • Welcome.  Was the mistake the car, or joining us? 😏
