R33 Blowing White Smoke When Hitting Boost

[jezzathejerm]

My R33 is blowing white smoke when i hit boost.. only when i hit boost. i already got my turbo re-build by gcg turbos.. now its a ball bearing high flow turbo.. im running 10 psi have a boost controller, after market exhaust and thats about it.. everything i have read says turbo seal or head gasket or whatever... what should i do.. i have to drive to canberra 2moz but having 2nd thoughts now.. anyone out there know what i can do??

Take the car to a mechanic and have them do a compression and leakdown test. If that passes then you have most likely got a faulty turbo on your hand.

Not surprising due to all the chinese copy covers that GCG are using on their Garrett units now to save a buck.

it got sent over to gcg turbos and they said it would be a 3-4 day job.. didnt get it back for 2 and a half weeks... my mate called them and abused them saying that he would never go to them again and the dude fixing the turbo had to do it on a friday night and we were thinking he may not have done a proper job cause we got the shits with him. its been in the car for about 2 months or so.. its been ok.. but now all this white smoke when i hit boost.. i just spent $3500 getting it upgraded and everything.. what a shit hey... and i dont even have anything realllly aftermarket.. what a joke i have on my hands.. and i think its also out of warranty

fark me! for 3.5k you could have gone GT3076 with external gate inc. fitting etc. IT would make way more than a highflow

i get my car fixed from the place where i bought it in sydney cause my dad knows the owners and they recon they give me a good deal on everything i get done there.. i got $3500 off the asking proce for the car but whave really had nothing but problems since i put the boost controller on there.. thats bout the only thing that has made the car have problems and im only running 10 pound..

Gee you seem to be having some bad luck,gcg rebuilt and highflowed my turbo 3 years ago,been running 16lbs every day no probs,hope you get it sorted.

[WYTSKY]

hey bud... u say its been having probs only after you put on the boost controller... are you sure its running 10psi? had it on a dyno? have u got a guage to tell you roughly how much boost?

what sort of boost controller? electronic or bleed valve?... u never know properly unless you dyno the car with those little aluminium key adjusting valves.

"never know properly unless you dyno the car with those little aluminium key adjusting valves" ... huh...? lol

Get a decent tuner (ie. not your dads mate!) to take a look. white smoke = bad news... oil is burning, so you've lost a seal somewhere. Turbo is most likely, but it could be a few things..

[FLY12N]

If its only blowing smoke on boost, sounds as though it would the the oil seals on the turbo. Bummer.

[jezzathejerm]

Found out what the problem is.. piston no. 5 is blown.. so i have to get a new block for the car.. when the turbo blew the first time some of the impella got caught inside the intercooler and now shreaded the piston ring... fun times ahead!

[Primordial]

Epic fail.. sorry to hear mate. Good luck with the rebuild!

[CRoNic...]

That's crazy!!!

I got same problem as jazzathejerm's on my R33 RB25 det . Blowing white smoke when hit boost. Just few days ago, it was blowing oil from BOV. most likely Turbo's problem, i booked a engine compression test on this Friday and see how that go. if that pass, i go for the turbo upgrade. AS 3lit3 says GT3076 is a very good option, and KKR 430 or KKR 480 can be a cheap and nice option too.
