Auto to manual

[Walter]

Okay, here it is...
I bought my Yaris because I was desperate to get out of a huge car payment on my S2000... and I think they look really cool (much better than comparably priced cars). After looking at a few dealers and not sourcing a 5 speed, finally one dealer charged me less than a 5 speed would go for... on an auto.

Im loving my car now and assuming I dont blow my tax return wad in other places, Im curious what all I would need for the transplant. I dont like autos and I know I would have a lot more fun tuning the car if I felt the potential driving fun in a manual tranny.

So my questions are:
1) Does anybody know if other tranny's will fit, or do I have to use stock Yaris (more cost effective to use something older, plus maybe get close ratios)?
2) I know our ECU is a pain in the ass, so will it conflict with a manual trans?
3) Cost (Im gonna have to put a new pedal cluster in, etc)?

Thanks in advance guys...

It will be cheaper to sell your car and get a new 5 speed.

Not an option, Im stuck with the upside down residual financing from my
S2000...

I couldnt sell it if I had to j

If you can afford to do this trans swap you could afford to tack another $40-$50 a month on your payment. That figure is assuming you will lose $2K or a little more on the sale of your car.

Unless you found a crazy deal on all the parts, or plan to do all the labor yourself it is not worth doing. It will cost more than $2K to do the swap when everything is said and done.

I would sell it wihout a problem if I owned it outright, unfortunately the bank does and I owe them about 16k for a car that goes for about 14 brand new

Guess Im stuck with the slushbox for now...

I know that sucks...

You could sell it privately at market value.. then roll the financing over again on to the new 5 speed car.

I don't see why this would "have" to cost $2000?

An echo trans would only run around $500, everything else you can just jam in your pants @ the junkyard ;).

The concern would be the ECU, now that could get pricey.

If the ECU could support it, I'd say it may be worth the effort... while your at it, you could possibly build up the trans and gear it as you please... or possibly swap in the trans from something else, although that will undoubtedly lead to much fabrication.

Also consider you could possibly get a motor and trans at teh same time, build both of them up, take A/T and current motor out and have them as a backup, or sell to offset (possibly pay for) the new motor and buildup.

I don't think it would be worth $50 a month (basically buying the trans every year), at least not for a car that should have low payments.

IMO, at least look into it, and report back what ya find out :)

Thats exactly what I was thinking, every word!
Considering the only worthwhile engine mods for the 1.5 are F.I., Im not about to rake out that much bread for 30hp. That makes a engine swap realistic...

Maybe start buying parts to throw on a engine stand in the garage and play with little by little...

And TX, thanks for the link! 6 speed Levin tranny is t!ts, that final drive would be nice!

best way, trade your Yaris to a new 5 speed, but you may have to buy a new bumper first before you try to trade it.

Anything that fits can be swapped, thats how I look at it.

I'd like to see a swap + F.I.... now that would be sweet :)

Could make for one hell of a sweet car if done properly.

Yup, maybe a MR2 turbo motor? Or tC, maybe Celica GTS with a turbo kit?

Walter,
This guy is interested in swapping a 5spd for a 6spd...sorry it doesn't really answer your question... hopefully you find it useful...

Nothing wrong with a built auto.

Not at all... matter of personal preference I guess. Personally I have a lot more fun running through the gears

also an option

well I'd "like" to see the 1nz built up... it has potential, and will maintain the handling of the car without major mods... 200+ to the wheels with a turbo, more with engine management/pistons, + very cheap to replace.

But yea, 300+ to the wheels reliably would be fun.

180-200WHP should be possible with a bolt on turbo and ECU tweaking, but that would really be pushing the limits of the stock internals...

Even with new rods and pistons, lowered compression ratio and more boost, I would see it hard to get more than 250WHP without the engine becoming an uncontrollably peaky little thing. There unfortunately is no replacement for displacement.

But we'll see, there's just so many unknowns at the moment. I'm sure this engine has been modded to the extreme and then some in Japan, but how can we access that sort of information?

Oh and back on topic of the transmission swap... Looking through those technical manuals, it appears the Yaris' computer management system is somewhat modular, so it should IN THEORY be possible to remove the AT control unit without affecting the rest of the systems, but I doubt it's such a plug-and-play system in reality.

You should look through page CH-17 of the chassis.pdf and BE-9 of the Body Electrical.pdf files (available in the DIY section), and see if you can make more sense of this The ECM module is the one that controls the AT transmission, but it looks like it also controls the combination meter, spark plugs, and so on...
