I have a 97 GTS25T R33. It drinks 13.8L/100KM in city. Now i want to reduce this number but don't want to lose power.

what mods do these things? like a S-AFC or a aftermarket air intake?

All i want is the car run economy way with the daily drive(i usually change gear at 3000RPM), and it can fly with the high RPM(till the redline).

Cheers!!!

An S-AFC will reduce your fuel consumption and increase your power, but don't go looking for a quantum leap in either. You might get +20 to 30 rwkw depending on what other mods you have, and fuel consumption might drop from high 13's to low or mid 13's per 100km depending on how you drive it. I think 13.8L/100km isn't too bad at all.

Edit: If you like flooring it a lot, your fuel consumption will probably go up with an S-AFC.

I don't understand what you said, sorry ^_^~

i have heard from a friend, he said that with a SAFC installed, you may increase your fuel consumption. and without better injetors, a SAFC is useless. is that right?

In theory, you won't ever use any more fuel with an S-AFC installed as it generally leans out the fuel map all over the place, so you get more power for the same amount of throttle used. But with more power on tap, there can be more tendency to floor it more often :D It's all dependant on the driver really.

Some parts of my S-AFC map increased the fuel flow, mostly in the mid range. But it wasn't in many at all and I still managed to generally save fuel when I had it running.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
