Sorry to ask the question everyone else has been asking, but mine seems a bit different.

Under light acceleration the car seems to blow a bit of white smoke, but when you accelerate hard and prob a bit after full boost (around 5000rpm or so) a big black ball of smoke comes out the back (just 1) like a cloud and then theres no more.

The car seems to still have its power (ran 13.2, stock 33 gtr), apart from that the only noise I started getting from the engine was a slight ticking when the car was first started in cold after an oil change, but was told this is just because of the thin oil (motul 4100 turbolight)

Do you think its an engine problem, or just running rich in top end and will be sorted with some tuning?

I have a PFC but ive been waiting till after I get the new turbos and other pieces on to get it tuned.

Sounds fine.

 Just the wastegate opening letting exhaust gasses out.

 

 I'd say white smoke might be from the oil getting hot and thin.

So he listens to your advice, then blows his motor....Good idea there mate.

All i can say is go get the Power FC tuned ASAP. Dont wait to do it later, unless you can afford a full rebuild....

Usually -

White smoke = coolant or blown ring land

Black smoke = excessive petrol

Blue smoke = Oil being burnt off

None of these is a good thing to have

We'll you never no i could just be the thin oil,

but what he described is exactually what happened to our project R33 on the dyno. white smoke after the run.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
