Ok where do I start...

So I have an r32 with a rb25 in it, end of last year i changed the engine to a new built forged rb25 with a new high mounted garrett gt3076. had all the bolt on mods pretty much everything done apart from cams.

So I did about 5000km on that until i wanted more power so I got a new Garrett T04Z and bolted that on and took it to the tuners via tow truck, they re-did the exhaust to a V-band and gave it a tune untill they found out my bosch 040 was maxing out at 5000rpm. So i went to the tuners and back a few times about a 10min drive, driving very slow and still had to take it back home to do more stuff to it because they were an absolute rip.

The car was running perfect but I didnt boost it to be safe. So I went all out and got a surge tank sorted with dual bosche 044's and a dual feed fuel rail and a new Jim berry full monty clutch. The first time i started the car with the new twin fed rail the car started smoking like hell real white smoke and it also sounded like its running on 5 cylinders. so i was thinking it was just overfueling or a plug came loose on one of the injectors or coilpacks.

Thats when i noticed that it was leaking oil from the bottom of the V-Band (so obviously it had an exhaust leak too) so I was very confused because this turbo is new. So I pulled the V-band off and there was oil in the exhaust. pulled intercooler and intake piping off and there was nothing. So i did a bit of searching and started with the easy stuff.

So Changed the Oil return and made sure it was flowing properly and clear. was running a -4 oil feed using a restrictor so changed that to a -3 and still leaking but i didnt think it would have been this because it would have leaked before. Checked the catch can set up just incase it was blocked and causing crankcase pressure and its clear and working perfectly but didnt think it would have been this either because I had this set up on my old engine and my new one.

Soooooooooo i got no idea now and just missed out on getting it tuned by Anthony Rodriguez so need some advice on what to do next.

Going to try a pressure test this weekend.

So the weird thing is it only started after I changed the fuel rail and added a few more fuel pumps and clutch.... SO pretty lost.

Any help would be great and no haters thanks

    • 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.
