what tranny to use

[SILINC3R]

when I get back from going underway I plan to redo the tranny since it is the original one that came with the car-250000+ miles and the only thing that has been changed is the clutch. this is a FWD drive car so I wondering if it okay to get a WRX tranny and just not use the drive shaft? also I hear it is ok to use the WRX flywheel as well. Since im building a N/A car the flywheel will help since it is lighter( that is my understanding about the WRX flywheel) with the WRX tranny I also plan to go with a short shifter as well just to make it all good.
I think this upgrade will improve the car over all and give me some lost power back. Also I have the cable clutch so im guessing I will have to upgrade also to the Hydraulic clutch whitch if I could I would like to stay with the cable. I think this is all that I can think of. Any input will be greatly appreciated. Thanks

Forgot, dont know if this will help but im keeping the car FWD and N/A. also I trying to make 200 HP at the most which I understand is a dream.

FWD?? ....N/A??

lol you shouldnt notice any difference if your tranny works fine and you need to weld the center diff or possibly use part of your trans regardless a waste.

You will also end up with lower gearing using a WRX transmission (3.9 vs. 3.7). I'm guessing you're staying with fwd for convenience and mileage, so the stock transmission would be better for the latter.

i want to stay with FWD and N/A for the weight and less rotating mass. if i went AWD I would have to put in a turbo. mileage is a plus.

so i should just stay with the stock tranny? is that what im understanding?

[ericem]

Correct keep up on replacing gear oil and keep it going! lol.

If it ain't broke, dont fix it.


Running the power through two wheels is a lot less stressfull than with an awd tranny. Keep it as is until you find trouble. A friend of mine uses FWD 5 speeds in his VW cars with a Subaru mid-engine RWD layout and is limited to about 250 whp with rough treatment.

I'm keeping mine fwd as well, but going turbo. Partly I want to keep the tallest final drive ratio for better mileage, partly to make it cheaper and easier on myself as I'm restoring the rest of the car and there's more than enough work in that. When it's done, it should be a good deal faster than my Mazda 3 and with some aero mods, hopefully beat or match it in mileage.

hmm my n/a leg wagon awd definitely felt faster then a mazda 3 like from 0-80kmh and the mazda 3 fuel economy i dont recall but my n/a wagon wasnt bad at 450 500 km a tank.

I'm getting 32 mpg/tank with a 34 highest in the Mazda. Didn't pay as much attention to the wagon, but with the N/A engine i think it averaged somewhere around 25-27 mpg driving like more of a dick. The wagon definitely has more bottom end, but after 80 or so, the Mazda would have wrecked it. Even more so if it didn't have a speed limiter, but that's at a pointless speed anyway.
