Expected Fuel Economy

[buzzboy]

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?

yer, if you care about fuel economy, dont buy the car

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

my car has 363rwkw and i usually get 500km's to a whole tank. sometimes more and if i drive it hard then it will use alot more petrol.

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

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

get a proper tune and it'll be normal
