I have an 86 non turbo rx-7 and it drinls gas ... i get about 240km on a tank ... does any one know of any solutions or even weight reductions

 

there is numerous threads on weight reduction. use the search button homie!!

 

lose weight and take out all the interior and get rid of sound deadning and ac p/s and so

 

have you gave your car a tune up in a while?

 

:

Instead of gutting the car FIX what is wrong with it.

 

If you take your car above 4k RPM, your gas mileage will suck *****.... if you take it above 4K RPM with your foot to the floor.... it will suck donkey *****... nature of the beast....

If you have a free flow exhaust.... your car is probably running rich on the top end anyway...

You can use an SAFC to take fuel out... AFTER YOU FIX ANYTHING WRONG AND TUNE UP THE CAR.... but have someone with a wideband O2 help you with this..

Check your tire pressures... low pressures eat gas.. agressive tread patterns eat gas, soft compound tires eat gas

Roll on the gas like you have an egg under your foot

replace your oxygen sensor if its old..

have your injectors cleaned......

 

new spark plugs and wires will help too.......

 

Air filter for sure, TPS sometimes, fluid changed. Just give her a good tune up and make sure the mix is right.

 

eat less =D

i think most of the things are said by others already... so thats my only advice =)

but do fix the car before mods.... or else it would suck

u would think, what the hell did i do wrong... and it would have been solved if the car was fixed in the first place
