i have been looking around and i have been unable to find any rwd conversion, how hard would it be to convert an 05 ce to rwd, im thinking that a supra rear end would fit the rear and the engine would need custom mounts and a bit of firewall work to fit a rwd trans,

anyone have any other ideas, or proof that its been done but iv missed

Small light unibody cars are not built for RWD conversions. You'd most likely need to build some sort of subframe to mount the rear axle / suspension to. The same goes for the front half of the car. Anything can be done if you have the time and money.

Frankly, I'd just buy something that is RWD.

All that on top of the fact that you will probably need to lengthen the front end of the car to fit anything but an extremely small 2 or 3 cylinder in front of a Corolla as the engine bay is way too narrow.

But seriously to undertake a project like this you would need to

Literally lengthen the car at the engine bay.
Literally scrap and redesign the entire floorboard.
Redesign the entire steering system and most if not all the suspension system as it all bolts to the Corolla's subframe which would almost certainly need to be scrapped.
The rear body, floorboard, and all would need to be redesigned at there isnt any room to mount any sort of rear end except for a Solid Axle rear end and even then it would need to be extrememly narrow. If you did want to mount an IRS you would literally be going back to the drawing board with the car with trying to get all the geometry correct with everything being straight and even.
Redo all the wiring, fuel lines, brake lines, proportioning valve, cooling system.
Strengthen the body in several areas.

I would say 30,000 dollars in an understatement. It would be easier to simply build an entire chassis with a drivetrain from scratch then cut off a Complete Corolla body and then somehow mount that body to the bare chassis.

I can never understand how these questions come up.

You do have to be a pro to do this. This is not "metal work" it is advanced chassis fabrication.

Let me give you an analogy that might put this into perspective for you. Have you ever had a kindergartener come up to you (if not then just imagine) and ask you what type of nails they should use to build a tree house, and then look high up into a tree and say they were going to build their own tree house up "there" and point?

Although you can't see it now, you're the kindergartener asking what type of nails to use. Except you want to have indoor plumbing and electrical in your tree house, along with multilevels and a jacuzzi.

I don't want to be a dick, but I'm going to tell you what everyone else should have said from the beginning, you'll NEVER EVER EVER EVER EVER be able to do this and I'll bet you your car vs it's value in cash it'll never happen. Aside from that, it isn't worth my time to continue talking about something that will never ever happen.

Corollas were RWD through the fourth generation (E70) and part of the fifth generation (AE85 and AE86). One of my college GFs had a second generation E20 and it was very definitely RWD.

You can probably buy a RWD Corolla for a song (and you can pick the tune) on e-bay now. Then buy a Supra rear, a Sawzall and go to town!

Keep or sell the 9th gen, it's probably worth a few bucks.

Idea

Idea: Isn't the matrix available in AWD? Is it not the same basic chassis, motor, transmission and configuration?

Your car might be semi set-up for AWD already and with slight modifaction maybe even RWD (with two diffs).

I don't know... but with a bit of research a person could find out.

And with a wrecked donor AWD Matrix on the cheap from the auctions this guys dream could be very possible. Dare I say bolt-on even? Now thats a project I could get excited about! I'd love to be the only person with an AWD Corolla.

Anyone know?

The Matrix is (in effect) a Corolla station wagon. The problem using this platform as a basis for a RWD hot rod would be that when manufacturers convert a FWD design to AWD the rear system is usually an add-on and most of the power still goes to the front wheels. So the rear drivetrain doesn't need to be awfully beefy, and it's not.

Also they were only available with an automatic trans and the entire drivetrain is inherently weak.

As for the idea of buying a RWD Corolla (AE86 and prior) the OP never makes any mention of considering that. He has an idea for a RWD 9th Gen Corolla (and if you guys read correct possibly with a V8).

This is just not something that can be done easily. Not by any stretch of the imagination. It is just too much work. You have to lengthen the front end significantly (probably a foot or more), redesign the entire floorpan, redesign the subframe and steering system (as our 9th Gens use a K-member and you wouldnt be able to bolt an engine longitudinal on it unless the oil pan was somehow offset, dry sump, and could still be mounted. Then the suspension system would have to be completely reworked and geometry (camber,caster,toe) figured out. Then you would need to route exhaust, brake systems, wiring, safety systems and everything. This would take way too much money. Which is why I said it would be easier to simply build a full tube chassis with drivetrain, cut off a 9th gen Corollas body and slip it on the car chassis and somehow mount it.

BTW if you have a TE72, AE71, or AE86 a MK1 Supra Solid axle rear end is nearly direct bolt on. It only requires swapping the spring seats and purchasing or making a set of adjustable 5 Links. And since it is an F Code 7.5 In the LSD assembly from a MK2 Supra or most any aftermarket 7.5 In truck stuff drops right in. Just food for thought.

Happy thanksgiving.
