Compression Tested

[Adz2332]

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

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.

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.
