Adz2332 Posted September 18, 2007 Share Posted September 18, 2007 I have a GTST Series 2 R33. Im looking to put new turbo and injectors on it. taking it from 200kws to around 275kws... My thing is though before i do it is it worth getting a compression test done and a general look over the motor to see if its ok? Also if something comes back negative is there things i can do now to make it perfect again before i shove the turbo on? Or should i just put the turbo on and hope for the best? Anu other ideas would be appreciated also Link to comment https://www.sau.com.au/forums/topic/185510-compression-tested/ Share on other sites More sharing options...
abu Posted September 18, 2007 Share Posted September 18, 2007 (edited) Get a compression test and a leak down test done. That will give you a good indication of how healthy the motor is. Compression test you can do your self if you have a tester. As long as they are generally fairly even (1 - 2psi variance) it will be fine. Expecting around 150psi/cylinder for a healthy Rb25.

Bad compression test would probably indicate that the rings are worn, which is why the compression is low. Ummm.. rebuild I think? lol Can't do much else if you have low compression.

LatinR33 Posted September 18, 2007 Share Posted September 18, 2007 (edited) dont forget a leakdown test also will give you a better indication of your engines condition. Personally if your using your car only for street use 200kw at the wheels is a pretty quick streeter so if the car is running good now and the comp test comes back borderline/average then atleast you'll still have a quick car as it is.
