Ok, here it goes...
1990 GTU (non-Turbo)
my car gets 10 MPG! since im gettin crappy MPG why not swap but with what?

I AM GOING TO RE-NEW this car!
i love it but should i just work on the rotary engine or put something else in there
guys gimme some HELP!

im thinkin new exhaust (borla or racing beat) k&n filters etc.

thanx for the help!!!

 

I get 19/26 in my S4 N/A... and about 15-20MPG in the 82 GSL... how are these other guys always getting such crappy gas mileage???

 

something is seriously wrong with your car. i suggest you figure out what it is before you drive it again. a giant fuel leak could literally kill you.

 

Yeah, 10 mpg is abnormally bad, unless you redline it litterally everywhere and only use the first 3 gears. The fuel filters and o2 sensor probably need to be replaced, plus the injectors probably need to be proffessionally cleaned, since its probably never been done. Is there anything obviously wrong with the car, like major lack or power or something?

 

I would think fixing whatever is causing your poor gas mileage would cost you less than swaping an engine.. because apparently you don't have any spare piston engines laying around to put in it.. so thats going to cost you $$ to buy one.. more $$ than ur losing to poor gas mileage. Depending on what v8 you drop in if that's the rout you go (seems to be most common). lol ur gas mileage could even stay the same as it is. but if you find your rotary has poor compression and needs a rebuild.. well that's another story and no cheap solution... i suggest finding out why its getting poor gas mileage first off.

 

I would agree that you need to find the reason you are getting such poor gas mileage. I typically get 18 to 20mpg and that's with the 4.3 rear end.

 

I drive in the city only! no highway drivin. i am going to get this car checked out cause i believe 15 MPG is the normal. i gotta spend some time on it. right now i drive it to work every day. i do drive aggressively but not always when i get that need for speed.

do you guys have any suggestions on how to get more MPG???

 

swap in an ls1 v8 and get great gas mileage

 

If he has that kind of money, sure.

As mentioned before: o2 sensor, all the filters, plugs, wires, and your cat is probably plugged to ****.
