i bought a r33 gts-t from the auctions. sounded sweet, drove fine. Got the 100,000 service and mechanic said its fine. then i started noticing shocking fuel consumption!!1 like 290 off the whole tank and alot of black smoke on the muffler. ive driven it for a month and decided to check the oil and its almost all gone :S

does this mean the engine is dead? or something else???

cheers

yeah like there doesnt seem to be a huge leak of oil any where :S could the mechanic have forgottent o put oil in(doubt it). im not worried about the black smoke cuz i think its petrol not oil but where did the oil go?

the car drives normally, th eoil pressure seems fine and so are the temps? there is no gray/white smoke :S

Change the oil again and check it every day to see how much oil it is using.

Black smoke means its running rich - not oily so you may not need to rebuild the engine. It may just need to be looked at by someone who knows what they are doing.

A *little* oil around there is not a big issue, but check the O2 sensor thread. Apparently Nissan recommends changing that sensor every 40,000K's and I doubt your mechanic did that. Then hit up the spark plugs if he didn't change those, if he did, find out what went in there and check that they are the right gap and heat rating.

After all that, reset ECU and let it relearn?

Wat happens is the seal on the turbo goes and it will suk oil through the turbo and out the exhaust

it happened to my TX3T and i needed a total engine rebuild + turbo rebuild and a mates 2.6t sigma engine just rebuilt with no turbo rebuild and his shot oil out of the exhaust

a turbo rebuild solved it

yeah im with R31Nismod heer, if u had low oil ud see the warning lighjt and ur oil pressure would be low :S make sure u check the oil after then engine has been off for a while so it can collect,

cheers

btw if there is no grey/white smoke then ur engine is probably fine, if ur losing oil it might be a gasket somewhere, you should get it checked out either way

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
