1jz in a Z, gas mileage.

Recommended Posts

I've gotten 41 MPG with my 1JZ 240z, with an r154 and 3,54 diff. 

 

This was the absolute max cruising the back roads on a 400 km stretch of a road trip.

 

I usually fill up around 34 MPG using it to drive to work, and got about 36-37 driving across the country this year. 

 

(These are US mpg)

 

Running stock engine with a Holset Hy35, Haltech ECU and cruising AFR of about 16:1 and pretty advanced timing (30-40)

I've been running my 240 with soarer 1jz for over 3 years now. Car is not really a daily driver but I do drive it to all trackdays, drag racing, and car events. I always get over 30mpg if I stick to around 80mph on the motorways. Pretty standard engine on factory everything apart from boost.

Just curious what octane level of fuel you have available there? I just bought a 2jzgte from an Aristo and am in the process of sourcing E-85 fuel components. Here in California we only have garbage 91 octane available.

I'm glad this thread is still going on as I advance in my swap. I don't recall seeing anyone in here running a 2jzge na-t as I will be. My plans are a stock 2jz (injectors, ecu, the works) for now and a HX35/40 turbo. I'm not building the car for efficiency but if it could do better than my ls400 I would have a reason to daily the racecar  B)
