Legit Auto To Manual Thread
Hey guys,
So, I was wondering. I know that for anyone who said "going to manual from an auto in a Cobalt would take far too much money" that's a valid statement. However, what if you bought a complete parts car ,and theoretically swapped everything out. Likewise, tranny, linkage, shifter, pedals, ECU, etc. Would that be doable? If so, would it need to be another 2.4? I'd assume because of the ECU. But is the tranny the same? Even if you got a complete 2.2, could you swap everything out, and just locate a 2.4 manual ECU? I mean, I really don't see how it wouldn't work if you have a complete parts car to do this with.. Not saying I do, but just wondering.. Because if I end up keeping this car long-term, I'd like to swap to manual (if possible) and do a full motor build with boost..
Anyone? I can't be THAT crazy..

Is it possible, yes. Still gonna cost alot cause a "parts car" won't be cheap. Other then the engine and ECM I believe that every thing drive line should be swappable.

That's what I figured.. Now, if you got an SS s/c as a parts car, you could then also, more or less, swap all of the s/c stuff also, and thus only needing a 5-speed 2.4 ecu to tune for boost, correct?

back when I did the research, I checked into even getting the ecu re-configured instead of swapping. From the talk I had with the pro tuners, this is possible. The only question I still havent answered is if there is a difference in sensors, connectors, and so on.
Still, this is all a very large project to undertake without help from a professional.

I would assume. It's very much all just talk, but I was just wondering if it would work.. It's not like my Olds where I just get a motor, bolt it in and fire it up.. lol But I figured I'd check. I would probably only do it with an SS s/c so I can go boost too..

So basically:
Buy an SS s/c as a parts car.
Swap over the entire tranny set-up to run manual.
Swap over all applicable s/c stuff, then finish what you need.
Find 2.4 manual ECU, tune for boost.
Drive away happy with a s/c 5 speed 2.4.
The basic set-up?

I think you also need things like BCM, all wiring harnesses for things like all marker/brake lights, etc. basically you would need just about all the wiring/ computers out of a parts car and swap them into yours. Everything is tied into everything else in new cars.

Just get a turbo kit from ZZP for your Auto and call it a day. 260HP is still fun in an auto. And a whole lot less money.
If I had an LE5 my mods would be the following.
Forged pistons / Rods
ZZP stage 2 with 60# injectors.
And a great tune.

According to all the posted sources I've researched the 4t45e is rated for 200-210ftlbs engine torque, people seem to quote gearbox torque which is a different animal and much higher @ 300+ ftlbs. The lower figure is the correct one, any stage 1 project with a auto tranny and some preventative maintenance like tranny coolers and regular atf/filter change outs should function just fine if not subjected to constant abuse. The auto HHR SS made 217 ftlbs so obviously GM felt comfortable warrantying that level of twist in its transmission.
Personally I'd start to get nervous past 250ftlbs, but ZZP has a 4t45e upgrade in the pipeline that is good for around 100+HP (their words) but no word on torque...

Many cavalier/sunfire owners have done this. I know it is not the same exact car, but it is very possible. The frame is the same, and it "can" be done.
We sell conversion brackets for the cavalier/sunfire, we were one of the first to do it back in the early 2000's.
