3S gearing, I'm shocked!

Anticipating 17 city/24 highway on E-85.

Exact numbers I get. There's more there if I would take the time to lean it out / drive like a sissy but I just don't care that much.

If you had a manual FWD car there are some really nice extra overdriven 5th gears available. I went with a 12% taller 5th on my last car and achieved some very good mileage. It would get at least 27 and often 29. We cracked 30 one time on a long trip.

IIRC it was around 2000 RPM at 60.

It used to be atx and I usually got 24-25.

I got 29 hwy and 22 city in my 96 R/T with 291,000 miles on it. Hans must have work his magic on my 5th gear when he rebuilt it lol.

You guys are all awesome! Thanks everyone. On every other forum I've joined, I wouldn't get that many responses that quickly, and normally there's be some bashing.
If I find any DOHC 6G72 at any local salvage yard, then I'll drive the F4A33 exactly as Mitsu intended it until spring of 2013, when I'll have a six speed.
The torque converter upgrade was appealing, based on past experience, until I found the price is so much higher than for a 700R-4.

Also have seen 29 more than once in my car. MPG isn't always about low rpms, plenty of mazda's and nissan's run well over 3k rpms at 70 and still get great mileage.

A 6 speed non-turbo is going to be an absolute dog... good luck with that.

I continually got that kind of gas mileage before and after we rebuilt the 5th gear issue. That car is straight up magic I tell ya.

This is what I was going to say.

As for fuel mileage, I got 25-26 daily driving my Stealth. I've gotten over 28 on a trip before and I wasn't really trying to get good mileage. I ran 75-80 mph most of the way. This was with a factory geared NA 5 speed. Had I had the taller 5th I would have easily been into the low 30's.

Just drove to San Diego and back from Phoenix last weekend. Averaged 25 mpg. This is with an average speed of about 85, and several high speed runs. Not to mention having fun going through the mountains.

To the op, I don't know what kind of Dsm you had, but my talon was at around 3600 at 80.

Hey all,
While I have enjoyed an '88 Conquest TSi 5-speed, a '95 Probe GT 5-speed, and an '85 300ZX 5-speed, I'm mostly a Camaro / Firebird guy, except for a few Mustangs.
I did a carbureted 5.7L '78 Camaro that managed 25.1 MPG at 65 MPH with the ignition advance being way late. I used a 700R-4 automatic, and was geared for 1800 RPM. A year later, I drove a second-gen Eclipse 4-cylinder, which, to my extreme amazement, would also cruise along at 65 MPG doing just 1800 RPM! Great!
Just now, unable to sleep, I looked up all the gearing options ever used on any / every version of these cars. Very sad. The best possibility is the 6-speed, which is 1940 at 65! Can any of these cars even see 25 MPG? And my automatic, ( which is geared identically to '90s Cummins-powered Rams ), is 2300 at 65! Even then, it doesn't have enough first gear, even with the 3.958:1 final. We get a 10.1:1 first, when I know from experience that an 11.4:1 is great for a similar-weight, same-tire-diameter '88 IROC-Z 5.7L with a shorter-runner intake manifold.
I can see I'll need to do a 6-speed swap to like this car. Yet having done the whole Fiero thing, I'm thinking of the F40-MT2, ( not Ferrari ) which would require custom axles, flipping the engine around 180*( or outright swapping a GM V6, in my case ) and would give a cruise RPM of 1870. Plus the trans itself can be had new for under $1,000 delivered, and has proven strong enough for 500 HP V8 swaps. Ratios are 3.7692 / 2.0400 / 1.3208 / 0.9538 / 0.7547 / 0.6208 with a 3.5455:1 final.

how about you just stay for ever alone and go back to your whatever
