Hi GMF!!!

Just bolt in 3.52 tranny on my 3cyl ‘95
And unknowingly the outcome is doin ok,
but due to my new job mostly in downtown(not usually solid flat, uphill/downhill,
and so much of stop and go traffic lights)
I’m aware and I have read here That MPG would be suck in the city driving.

My question is, could I still get away with the 3.52 tranny
If I’m after with the fuel economy e.g. by doing that 3tech cam and gear?
Or also along with replacing my 175/70/13 on all 4’s with
a lil’ smaller tire but still on 13’s?

Thank you in advance GMF!!!

Note: But if all of this is not gonna be on FE that
I’m after with, maybe I’ll be finding those
stock tranny for 1995.

You will have you stay in the lower gears. Lighter rims and and smaller tires would help some too.

I dont know how it even moves with a 3 cylinder. I have a 3.52 in my 98 sedan with the 1.3 4 banger and it does ok but have to slip the clutch a little bit more than with the 4.39 that was in it.
98 LSi 4 door 5 speed-the nice one.

Going from 4.39 to 3.52 is a HUGE jump, going to be hard on the clutch (and the patience). The only way I would recommend this big a leap would be for pure, flat highway. There are two other steps in between that would be a better choice. If your engine is in excellent condition with an XFI cam or economy cam with advance sprocket, and you're a very patient sort, then maybe it would work. Mix in hills and a lot of stop and go and you'll probably be miserable.

Shorter tires would help, the 165/60-13's that came on convertibles had the same overall diameter as the 12" wheel/tire combination on the GEN2 cars. That would change your gear ratio one step shorter, problem is, you've gone three steps taller. If you went this route, get a speedometer drive gear from a car with 12" wheels so that your speedo/odo still read correctly.

I have to repeat everything Woodie just said.

I put a 3.52 in my 95, so I can speak from first hand experience.

My daily commute is generally 200 +/- miles, so lots of hiway. Driving the 3.52 would generally be like driving a four speed, with 5th for interstate driving only.

At what speed, assuming traveling over flat-ish terrain, are you able to engage 5th, and at what speed does it start to bog down? How low can you get your engine rpm's, before it bogs down?

I still have yet to install my 3.52 tranny, but I'm wondering if I'll still be able to putt along at 50mph with it in 5th, after I do. I can do it now, with my stock 4.10 tranny and 178/70/13's, but the car is right at the edge of bogging down on me. If I get much below 50 mph, it doesn't like it, and I'd better be coasting downhill, or be prepared to downshift to 4th. But if I can get the same mpg while going 60-65 mph as I do now by putting along a 50-55 mph, I have no problem doing that.

Of course, things like:your cam, your tire size, and the extra weight of your car vs mine, would factor in heavily to greatly skew any real projections of what I can expect with mine. Dan'o, probably has the closest setup to what I'll be running, eventually.
I attempted to take one of those on-line quizzes, once. It was supposed to determine which one of King Arthur's Knights of the Round Table I would have been. After wasting ten minutes of my time on goddamn click-bait, I finally gave up and said, "Fuck it! I'm Sir Cursealot!", and went back to surfing porn.

Been out for awhile...apologize for my delay reply.

@freegeo, Thanks alot, I'll keep on mind on that small tire and lighter rims, might try, but stayi'n on low gears-argh!

@MarkZ28, Thanks you! and with this 3.5 tranny, is it suck on city drive, on low gears alot and staying away on uphill alot, but highway damn so smooth, quiet and experiencing awesome low rpm's at 5th gear(they say felt like on 6th).

@Woodie Thank You! Yeah it is a huge jump and got speedo issues alot. thought about that XFI's cams and advance gear, I have some extra parts, might DIY it, like compJake did here in the forum(was posted few years back), and also might check 165/60-13's.
Thou, still mostly me driving around the city much would'nt help, like you said pure flat, and mostly highway is awesome!

@sphenicie and PTA2PTB - thanks....highway saves a lot of gas at 3.52 and mostly now is a pain driving around low gears at town.

What if changing transmission to 3.79 or 4.10 would help for sure I think?
