Just Got My Compression And Leak Down Test Back

[The Mafia]

Car is a R33 Series II 1996 Skyline GTS-T, 90,000 kms. Had 72,000 when I got it.

168,169,169,168,169,169 - 2% leakdown.

Car has been running 12psi 210rwkw 420nm torque for about 12 months now, and I am not the most steady driver. I don't mind getting out and getting on boost a lot.

With all that sorted, next weekend, on goes the 550hp GT30.

Is this a good result? I thought it was.

That is very good. Standard compression values according to the R33 service manual is approx 173 psi and the lower limit being about 130 psi.

[The Mafia]

awesome, thanks for that. Looks like I got me a little gem.

Now lets hope the tuner looks after the motor when tuning.

who else has had leakdown tests performed?

2% from a nearly 100k motor that has been modified for a few thousand ks is amazing isnt it?

When I bought my car odometer said 150k and leakage was 9% on the worst cylinder which I was told was satisfactory.

Out of curiosity, what oil do you use?

[The Mafia]

I use Shell Helix 5w 40 and replace it every 5000 - 6000 kms

I really do hope the tuner looks after it too.

where abouts did you get the test done, and how much did it cost, how long etc?

i had a compression test done before i bought the car ... and i got 5% .. its a 93' S1 33 ... done 114,000km's had been running 10psi for 4 years in australia.. and possibly more in japan.. stock apart from bleeder and i got 151.3kw

i was told this was fairly good also

good to know that the theory that rb's are very hearty is true
