I may be getting a '90 240 coupe w/ sr20det, with alot of the interior stripped, and a t-28 turbo w/ bigger intercooler. But it has stock readend and tranny, so does anyone know what kind of mpg figures I could be getting? My buddys gets like 15-18, and she doesn't even really beat on it.

 

man I think 15-18 is waaaayyy to little. I would expect something around 24.

 

With a T28 I would say about on average 23MPG.

 

not really if he gets on it alot he would get like 17 mpg on stock boost. and if he really really baby's it you can pull like 26mpg. only way to get really nice mpg is to tune it that way

 

depends on city or highway. i got about 25 highway and 18 city on a stock 89 coupe.

 

BOUT 26 with built sr

 

is there anyway to setup your low throttle setting on an afc to get 30 mpg hwy without detonation issues or do you need a full standalone?
