rweddy Posted September 10, 2007 Share Posted September 10, 2007 I have been toying with the idea of dropping a turbo in my LS wagon for a while and I came across a very nice touring wagon. What kind of highway mileage can I expect with the 2.2t & auto? How durable are the Auto tyranny’s and are these better than the regular autos?

Reveeen Posted September 10, 2007 Share Posted September 10, 2007 What kind of highway mileage can I expect with the 2.2t & auto? You are kinda asking: "how high is up"? Driving @ 100k/hr (60mph) with a light foot I get 32mpg (imperial). Driving like an "animal" @140k/hr+ (100mph+) I get 10-14mpg (imperial) '91 Sport Sedan 2.2t + auto Quote Link to comment Share on other sites More sharing options...

Good point there :cool: I was just looking for some real world figure, I get 30-32 range now with my na 2.2 5spd LS wagon & just wanted to make sure I would not be going down too much. Thanks!

Reveeen Posted September 10, 2007 Share Posted September 10, 2007 Keep in mind an "imperial gallon" is 1/5 bigger. Quote Link to comment Share on other sites More sharing options...
Manarius Posted September 10, 2007 Share Posted September 10, 2007 If you do primarily city driving, the turbo will eat your mpg - probably 16-18mpg city. The tranny's are just fine. Quote Link to comment Share on other sites More sharing options...

I do nothing or less than 10% city. All my driving is to/from moutains & around moutains in Colorado. I really am looking for more power but don't want to deal with the 2.5 HG/ pia spark plugs/ for a their nominal power increase. And I have to have a sunroof, hated not having one in my 96 OBW.

Well, you'll probably do all right. The transmission is a good transmission. Just check for torquebind and what not. The EJ22T is only 160hp. If you need more than that stock, you'd have to jump to a SVX. Quote Link to comment Share on other sites More sharing options...

I thought a turbo would increase your mpg as long as you don't drive it like it's a sports car. I thought pushing all that extra air into the engine would make it more efficient when driving normally, and provide extra power when you want it. No?

Having a turbo makes you get less mpg. Why? On boost, you're pushing more air, but you're burning more gas also. Quote Link to comment Share on other sites More sharing options...
Reveeen Posted September 10, 2007 Share Posted September 10, 2007 I thought a turbo would increase your mpg as long as you don't drive it like it's a sports car. In theory............. The trouble being that as soon as boost is seen the computer dumps in extra fuel. Stock with a 2.2 this happens around 3100 RPM, keep it under 3100 and you are "golden". Start modifying things, and this changes. With an after market crossover pipe (1/4 the price of OEM, and oversize), a cat less down pipe, and a punched cat, I'm making boost @ 2100. In town, driving like an idiot, this means about 8mpg, but "fun" (or who says a 4 wheel drive Subaru won't torque steer?). Quote Link to comment Share on other sites More sharing options...
eryque Posted September 10, 2007 Share Posted September 10, 2007 Thanks for the explanation I guess nobody gets a turbo because they want extra gas mileage, so it makes sense that they tune it to produce as much power as possible. Quote Link to comment Share on other sites More sharing options...
Reveeen Posted September 10, 2007 Share Posted September 10, 2007 I guess nobody gets a turbo because they want extra gas mileage Small correction: PREMIUM gas mileage. Actually I had a run of turbo cars show up for cheap, my Legacy was $400, a turbo 9000 Saab came for $100. Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted September 11, 2007 Share Posted September 11, 2007 Up in colorado, I'd say a 2.2l turbo would be better than the 2.5l N/A. The altitude really sucks the guts out of the N/A motors. The turbo will compensate for the altitude change and still be pulling the same power. Quote Link to comment Share on other sites More sharing options...
