Rb20 Turbo Problems?

[R32_Damo]

Hi i have a RB20DET and i have just changed my turbo and as soon as i start the car it seems like theres white smoke coming out and it doesnt go away after driving ect?

Also have oil in the turbo intake where airfilter is its all coverd in oil???

Ive neva driving a RB20DET b4 but it feels so gutless comes onto boost but doesnt do nethnig? Just put a RB20DET into a VL.

ALso i have a custom 4in dump to 3in to cat, Would the 4in b to big, or shouldnt this be a problem?

How hard should the RB20 got, how noticeable should it been on boost?

Thanks for your time, DAMO!!!

well the rb20's aren't the most powerful motor out there, especially pushing the weight of a vl.

by the sounds of it the turbo you put on it cactus. does it blow smoke when you rev it while driving, or just at idle?

The engines prbly not tuned very good at mo, tryn to get it finished b4 gettn a good tune.

When you rev it smoke tunes black then starts white back on idle?

still not a good sign. white smoke is never a good sign.

White smokes turbo smoke tho, coz with the other turbo it neva white smoked, just major black rick smoke?

[mad082]

the black smoke was probably unburnt fuel. especially if the car has an after market ecu and hasn't been tuned. if it is reasonably stock then black smoke might not be good either.

the typical 3L RB30ET should be fine. More torque and power than RB20DET, unless you've gone the RB20DET into the NA VL? And yeh, white smoke ain't good smoke. Even so, check the oil cap and see if the oil is clear and not in anyway a milky/brownish-white colour -> Cracked head if the case. But hoping for the best :S
