Hey guys

I’m looking at buying a mate’s skyline r33 .he basically just wants to get rid of it now after having a kid and needs to settle down. He has put a lot of work into it and its making 300rwkw .my only problem with buy the car is fuel economy.Next year I will be working full time, which means I will have to drive a lot more.

The o2 sensor (the one used for regulating fuel for constant driving like on the freeway) is broken (I have been told it’s a $50 job) so he can’t give me an accurate number; at the moment it’s doing about 200ks to a tank. Does that sound about right? How much do you get from a tank? What should I get a tank? If I run the boost at about 7psi daily what kind of economy should i expect?

Modifications:

Bigger turbo (td06 25g) running 1.2bar max

Intercooler

New ecu

Hks mid lift cams

Upgraded fuel pump and injectors

Exhaust

Thanks

Ooo tough choice ey, if your THAT worried about fuel economy then you might have problems because you either

A: wont enjoy it to its full potential or B: will go broke buying fuel every second station.

Would I be right in assuming that with a new o2 sensor you should expect no more than around 250-300ks to a tank...maybe a tad more

if you drop the boost...also depends on the tune?

my car origanally made 500kms to a tank until i had a new ecu placed in my car it now makes around 300km a tank on a good day the problem is the tune which is being fixed at the moment by another tuner who knows what there doing and have it tuned for economy, 300kw is great but you will start to hate your car when you see that fuel bill

If you worried about fuel economy, then thats definetly not a car for you. I dont know if I was looking at a daily driver I doubt id be getting a skyline except for the V35 since its pretty comfy lol.

Sorry a bit off topic, but is that your car in your sig? Damn that looks sweet :P

or if your super keen on the car and its a once in a lifetime opportunity.. buy a bunky to get you around during the week and keep it as a weekend car?

to be honest even changing the o2 sensor wont make it a super fuel efficient car.. I Think juts about any straight six turbo motor driven with some enthusiasm is going to drink the juice

    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
