The timeline on this is a bit off because I'm just copying and pasting from my local racing forum, but I figured I would share the build here since I've gotten so much info on my engine from this site.

So I have had this Corolla for about three and a half years now and it has undergone some crazy changes over the years. I'm not going to get into too much detail now, but this build will be ongoing through the winter here in preparation for the 2009 racing and drifting seasons.

My ultimate goal for 2009 was to have myself and the car ready to run the GT support race at the Edmonton Indy, but it's not likely to happen now. I'd prefer not to rush things and just build the car right the first time, so we're taking it easy. If I get to run a few events this summer, fantastic.

Here is how the car started out when I bought it back in 2005. All that was done at that point was the MKII Supra wheels and a crappy Ractive intake filter.

I drove it that way for a few months, then lowered the car on some Eibach springs and drove it that way for most of the summer of 2006. As you can see, the springs were a bit soft.

That winter with the help of Glenn (Supradevil) the car was boosted and received a few suspension changes. TRD shocks, ridiculously stiff AFCO springs for the rear. It drifted, but it wasn't pretty.

So in the summer of 2007 the car underwent a transformation. The engine popped in the fall of 2006 from my being a dumbass and overloading it at low RPM on the highway. So that engine came out and another stocker went in, with which I spent a little more time paying attention to the A/F ratios and it ran solid for the next two seasons with a LOT of track and street time.

The majority of the transformation was cosmetic in 2007. The car received new paint, real suspension (coilovers in the front, Swift springs in the back, Tokico Illuminas all the way around, Cusco anti-sway bars, fender braces ... and the list goes on). Also thrown into the mix were some 15x8 0 offset Sportmax 002 wheels.

At the end of the day, literally the car was painted in a day just before a drift event, the stickers were put onto paint just 16 hours old, this is how she looked. The kit is v-speed, cheap, but it works.

The car stayed that way through the 2007 season and held up quite well, save for an exploding ring and pinion.

Then the car received some more upgrades in the spring of 2008. Origin wide body fenders, proper JDM bumper lights and some paint touchups.

At the end of this summer I decided to take the plunge and step up to 17s. Normally they look crazy huge on a Corolla, but the right wheel can look decent if you ask me.

Next up, the true definition of a transformation.

The car has gone through some changes, for sure. But nothing compared to what's currently happening. The car has been stripped down completely in preparation for sandblasting and a basic primer before it comes back for all of the fabrication work.

The plans for the car over the winter include:

- Full GT racing spec roll cage tied into all suspension points in the car
- Lexus 1uzfe 4.0-litre V8
- Fully built MKIII Supra R154 5 speed transmission (already being built in Calgary)
- All of the ridiculously expensive custom parts from Australia to adapt this transmission to an engine that never came with a manual tranny
- Custom one-piece driveshaft
- Nissan S13 independent rear suspension and differential(s)
- Custom coilovers at all four corners
- Upgraded brakes, likely Z32 calipers and rotors
- Wilwood clutch and brake pedal assembly with dual brake master cylinders and built in remote-adjustable balance bar for adjusting brake bias on the fly
- Standalone engine management
- Custom gauge cluster
- Fully rewiring car from scratch
- Custom trunk floor made to house fuel cell, surge tank and battery securely and safely
- Dual fuel pumps to ensure surge tank never runs low on fuel
- Custom housing for coolant, power steering and washer fluid
- All windows removed, side and rear replaced with Lexan, front with new windshield
- Bracing removed from trunk, hood and doorskins
- A whole schwackload of smaller changes to the interior and exterior

The car was stripped down over the last week or so.

This is how it sat about five days ago. Doors, fenders, engine, front suspension and most of the interior removed.

A whole bunch of the interior crap that was pulled out.

Taking stuff out of Glenn's garage so things can stay nice and tidy while we work on the car. The engine, turbo setup and rear differential were snapped up by Corolla lovers ridiculously quickly.

Glenn welding together a bracket for the rear of the car to go up on the rotisserie.

And up on the rotisserie she goes.

Glenn prepares to cut out the trunk floor and panhard mount. I'm not sure I'll ever want to work on a car on the ground again after this.

corollabuild259.jpg

Here we can see the mounts for the rotisserie. There is another plate sandwiched on the inside of the frame rail. This unit is solid!

corollabuild267.jpg

So the trunk floor has been cut out and it was dropped off at the sandblasters to test how well the blasting will go on the paint and undercoating. We want it stripped completely bare to ensure optimum contact and strength in all of the welds.

Going off what the sandblaster said there shouldn't be any issues with blasting this thing right clean. After that there will be a bit of rust repair and some panels will be cut out and/or welded up. First thing will likely be figuring out positioning of the rear subframe and suspension. Once positioned the roll cage will be tied into all of the mounts. By the time the cage is finished the hope is that the parts will be here from Australia and the engine and tranny positioning can begin.
 
Off to the sandblaster/painter she goes.

Back on the rotisserie to make things easy for the sandblaster. They can tip the car on its side and basically just climb inside to blast nearly the whole interior without having to bend or strain or anything.

Picked up the car from blasting and primer. Apparently 25-year-old Toyota undercoating is tough as **** because most of it wouldn't come off, not a big deal since I was just going to be throwing more on. The only reason I wanted it off was to avoid any fires when welding the cage in. I'll have a fire extinguisher handy though, so it's not a big deal.

Couple pics from picking the car up.

Glenn's sled trailer worked well for bringing the car back.

Well some parts FINALLY arrived from Australia. Now that they're here I'm going to pick up the transmission from down in Calgary so we can start putting **** together and figuring out how to put this beast in the car.

Custom bellhousing and flywheel from Castlemaine Rod Shop in Melbourne. Heavy duty pressure plate and Exedy clutch as well, plus all of the nuts, bolts, bearings, shafts and u-joints I'll need to get this bitch rollin'.

We started stitch welding the front end the past couple days. Lots of chiseling, grinding, etc. There's just a bit left and then we'll get started cutting out extra metal in the rear end that is just going to be removed as well as part of the firewall and tunnel for engine/tranny clearance.

Plan is to drive to Calgary next Monday to pick up the tranny as well. Once we have that we can begin prepping stuff to go into the car for fitment, engine mounts, building headers, etc.


Chiseling out seam sealer. I then ground the rest of the sealer and paint clear for the welding.

corollabuild343.jpg


Panels were stitched on the inside and outside in 6" increments, and then again later in between all of those.

No it's not pretty what it does to the paint, but it was somewhat expected. Instead of having rattle cans made up I'm just doing to grab a gallon of paint and re-spray the front end once everything is built, fitted and ready to go in.

Not a whole lot was done until this past week, just too busy/being lazy.

Ordered all of these parts today. SPL adjustable rear toe rods, adjustable rear camber arms and solid aluminum subframe mounts.

We basically have the diff and rear subframe positioned and ready to go, as well as the S13 front subframe modified to bolt straight into the Corolla. It actually only took a tiny bit of slotting and it goes on there like it belonged there in the first place. Glenn has a theory that all of Nissan's sportscars following the AE86 were inspired by the little Toyota.

Here we go, finally. As you can see the S13 subframe (unpainted one) sits a lot lower and it will position the engine mounts about 3" further back than the Corolla subframe, a very good thing for what we want to do.

All bolted in. Along with the front strut rod brace/mounts.

Rear suspension is in and we did some test fitting on wheels. The 17x9.5 Hanbais fit nearly perfectly. Obviously this is drooped a bit, but up tighter there is a bit of clearance from the changing camber. I will actually be running 245s on the rear for drifting, not the 215s currently mounted. So with a little negative camber they should fit quite nicely.

New suspension mounts.

Assembling the engine for test-fitting. It will all come back apart later for brand new seals (the kit from Toyota cost more than I paid for the engine) as well as ceramic and powder coating on some of the more visible engine parts.

Bellhousing mounted on the built R154 for the first time. Bolted on without a hitch, very nice fit.

Firewall and rad support cut out in expectation of the 1UZ. It will all be sealed back up after with even heavier gauge metal.

Began fitting the engine here. After looking at using the rear sump pan we realized that the engine would have to go about 14" back into the car, which was just too much. So we swapped on the front sump pan and it's looking much closer to what I'd like to see. We threw around the idea of dry sump, but I think that's something that will wait for the future. A custom pan will be good for extra oil capacity.

Nice thing about the front sump is that the engine mounts line up directly with the stock mounts on the S13 subframe. There will be some modification, but overall it should be much simpler.

More pics. Engine mounts are pretty much done, just need to do some shaping on the plates to make them all pretty and round so they don't cut the **** out of our arms when working from under the car. You can't tell from the top, but there is about 10" of weld underneath the mount, so these things aren't going anywhere.

Much more room for the exhaust that I was originally expecting. This thing is going to be easier to work on than the 4 cyl ever was.

So at the moment we have the front camber plates from the S13 suspension positioned and mounted. The front control arms are going to be shortened, boxed and have a huge 3/4" heim joint added to the ends for adjustability and to avoid any binding that might have been caused with the stock arms by changing the caster angles.

The driveshaft is out at a shop being built as well. We found out the diff I have is actually from an S14, so we needed to add a couple of spacers on the nose mount, but other than that it bolts in just fine.

Exhaust is being built this week, radiator is being ordered today and will hopefully be in within a week or so. Once it's positioned the engine can come back out for disassembly, cleaning and to get a bunch of parts powder and ceramic coated. It's finally starting to look like a real car, so it's pretty exciting.
 
Went with IRS because the solid axle is a huge limiting factor for the Corolla in GT racing. Yes, I know it would have made more sense to start with a different platform, but what can I say ... I love my Corollas.

Smitherz - Yes it will be getting caged soon. Once the engine work stuff is done we will put the car back up on the rotisserie and finish all of the sheetmetal, then the cage, then paint.
