Thread: 1984 Toyota Celica Supra Build

I thought I'd share my build so far, it is still on going and currently on hold until I can move it to closer to school to finish it.

I bought this when I was 16 in 2008. I had a short experience wrenching with my Dad on his 1986 Porsche 928S and I had to have an old car. Shortly after getting addicted to wrenching on old cars sh*t hit the fan. Anyways I had some money saved and needed a hobby, at dinner a friend mentioned he knew someone with an old Supra sitting in the garage. 2 weeks later I went and took a look at it. I didn't know any other Supras aside from the obvious fast and the furious mk4 (I was young, can you blame me) the car was a blue/silver 1984 Toyota Celica-Supra P-type 146000km, minimal rust, no mods original everything so I bought it! Took me about a grand to fix it up, fuel pump, tank, tune up, exhaust was rusted out, fluids etc. I then brought it 6 hours north for a summer job and painted it did the brakes etc. The day I was leaving to go home with 3 harley's (Uncle/job partners) I was trying to play catch up and hit it 2nd to 3rd while merging onto the highway I wasn't on the gas real hard but I wasn't granny shifting either. Anyways 3rd gear went fine then I went to bomb 4th and kaboom! Split the block in half when the con rod broke away from the piston right below the wrist pin.

I stored the Supra in the back until thanksgiving when I bought another car with a JDM engine (terms to come below) and swapped that in. Drove it for a year, popped a headgasket on Thanksgiving day, rebuilt it with a few bells and whistles over the winter drove it for a week, then drove a WRX and wanted boost. I then saved for a new engine out of a 1989 Toyota Supra.

Quick run down of terms:
5mge is the motor that comes out of the 1982-1986 Supras
6mge is a JDM only motor, .2L bigger, same everything as the 5mge except has a 7mge rods (longer stroke)
7mge is offered in 1986.5-1992 “Mk3” Supras, it’s a 3.0L non turbo
7mgte is also offered in 1987-1992 “MK3” Supras it’s a 3.0L Single Turbo
All these motors are Inline 6
W58 is the 5spd manual transmission offered in MK2 (‘82-86)
The R154 is the transmission that came out of most, if not all 7MGTE cars again 5spd manual
The W58 is for the 7mge (non turbo) mk3 cars, and I believe is a little different than the mk2 W58
Ct-26 is the stock turbocharger out of the 7mgte


HERE IS WHERE THE BUILD STARTS: NOTE, the dates aren't exact. I started this build roughly October 2010.
So this is the “big one”

The Story:

I remember whenever somebody asked, why did I get a 20+ year old car for my first car at the age of 15?

I usually responded with, easy to work on and not all that quick (who was I to joke, these things are fast enough stock) I’m young and don’t want to wrap myself around a pole, my car means too much to me. So after blowing my 5mge, crying and complaining on the forums; I bought another pre-swapped mk2 6mge, threw the 6mge in my car, the next year (last winter) I did a mild rebuild as it was in good condition. Then, I fell into a bunch of Subaru friends, and drove a WRX and fell in love with boost, I kept throwing around the idea of just getting a mk3; take the easy way out, but even with my sagged suspension, massive body roll and squat I liked how the car handled, and after hearing all the stories of the piggies lacking handling aspects I decided to stick with my Mk2 Supra. I also couldn’t stand the thought of a car that weighs so much more. I love targas, but the thought of a power plant that is supposed to power a car that weights what 600lbs more than a mk2? Awesome.

The Car:






Old 6mge:

Bushings

I met up with local Supra members after hours of discussion of the 7mgte swap, wiring, turbos, trim, everything. We went for a rip around Waterloo while visiting a local shop (adrenaline motorsports, which unfortunately was robbed and burnt down a week later) . Damn its QUICK! Later we had probably my favourite weekend of 2010. The Toronto Supra Meet, where I got talking to the another local member located in Bowmanville (Mark) who said he had a somewhat toasted 7m block sitting at home, and chatted with George, probably the most popular Mk2 Supra parts distributor/supplier in North America about starting to assemble “The List” I bought a front sway bar off of member who came all the way from Newfoundland to tune his 726hp Mk4 Supra (Bruce/Yotaholic) and saw a bunch of beauty boosted mk2s at the tracking event. Along with the obviously menacing Mk4 that Bruce brought out, and some nice Supras of all generations. Thanks again TSC, had a blast!

So a few weeks later after playing phone tag with Mark, I hired a friend and his truck to drive out to Bowmanville to get the block. So we pull up with a shiny black Supra on the street parts car in the driveway and a surprise and a half in the garage. 7mgte block, pistons, rods, crank. All pre-modded for oil dipstick, oil pump modded to fit oil pan, a new water pump, and two turbos. Add a some green to the deal and we are down the highway. Before we do that we also go for a rip in Mark’s 7mgte powered mk2.… HOLY HELL it was FAST.

After talking to George again at stupid hours as he burns the midnight oil we also discuss exhaust, clutch, trims and my lacking issue of no “head” So at some godly hour of I believe it was. He said, “wait, you need a cylinder head?….. I reply with simply, yeah?” Calls me 5 minutes later with a price and a location of a cylinder head waiting for me.

2 weeks later I drive out to pick up this beauty: Brand new top to bottom Toyota parts.










Again with a very nice 7mgte powered White mk2 supra in the driveway. We talked for hours along with the same friend with the truck I hired for the block (who had at this point acquired a 89 mk3) so we all have related chats of 7mgte shenanigans and blabber on. There was a slight mention of a me trying to experience the boosted mk2s before mine is done to start to understand the beast. 30 seconds later we are heading down the street.

Nothing more was done. Simple Sunday drive in the night, and on the highway, and back…..and to the bank. We drove…..10 under the speed limit I swear…... Cough cough wink wink

　

This car was absolutely INSANITY, this is when I decided that instead of modifying trim and all that stuff which will cost a few extra bills I’ll stay with stock trim for now and change it later. (I ended up with a 57-1 trim with a .5" Larger inlet)


A box of goodies comes home with me as well, 6 new/used pistons because some knob at school decided to give me the “dropped piston mod” I’m not taking chances with possibly out of round pistons.

Stock, good condition IC

6 new/used pistons, rods

Front timing plate (the one I had off the block was damaged)

Cam gears

I’m sure I’m missing some.


I then made a call 4 days after picking up my cylinder head. In early august I went to the neighbouring city to look at a parts car (7mgte R154) before the plan was $800 for 305k km 7mgte, R154 and all electrical I want. When I talked to him (this was mid September) he said its still available but I have to pull and only on weekends. I told him that’d be a huge pain to drive 25 minutes each way and use my tools bring a engine hoist over and work on his mangled driveway and sketchy drive on ramps. So he said take the whole car, I asked how much. $500. When we get there all is well, worth the 500 but we notice only 2 lug nuts on each wheel which won’t do for the tow truck. We end up bargaining down to $400 and $50 off the tow truck because this is the only tow truck driver that is allowed to touch my cars. So I get engine, electrical, transmission my friend gets the rest and we fire it off the scrap as its rusted out anyways.

Bad news! I sent the engine to get machined last week, just decked is all it needed. They did the decking work and then told me after I paid that #6 cylinder is toast. There were two different score marks that were pretty serious, the lower one was located right around where the top compression ring would sit on bdc. So I'm assuming it sat with water or something in it. It pretty much honed out, not too serious as pretty much all combustion pressure is relieved by bdc. Then the other one that I noticed even AFTER the 1st one (originally it just looked like the oil we used for the honing procedure) Nope it was a fairly deep almost gash part way up the cylinder.

So this is the scoring, this is after a good honing to see if it could be cleared up





All the parts scattered




Blasted 3000 pipe with silver for basecoat the numbers will either be blue or black


Shaving the casting lines off the plenum, this will either be polished or silver hopefully with a cover as I hate the design, its ugly.

And the spare motor that was torn down after finding out the bad news:




So I will now be working on the motor that came out of the parts car. I already took out the crank and pistons today, which are in good condition. Downside, the 6th cylinder has the same wear right around bdc, but not as severe so I will measure the pistons, crank, rods and cylinders tomorrow while I was the block, get it decked and then I'll have to re-work the whole oil dipstick which was done for me already on the other block... not looking forward to that.

I'm sure things will be back on track new plan of attack:

Remove the rest of parts on spare block (from now on its the good block)

Clean in our "parts dishwasher"

Send it out to get decked (this one will be done somewhere else)

Measure rotating assembly

Balance Rotating assembly

Re-assemble Bottom end

Paint block + left over parts

and the rest is pretty basic

Cylinder head install, flywheel all external parts

　

Re-cap, parts are in, my original block was toast, so I sent it as well as the spare block (from the 89 parts car) to Canadian Cylinder Head in Scarborough Ontario. After about a week of work there my parts (block, pistons, crank) came out a lot better than I thought, the original silver block was toast, but the parts block was salvagable and was brought up to specifications. The pistons were measured and crank was inspected. I am very satisfied with their work!

So since then, I put in the new arp hardware which consists of Main studs, Connecting rod stud/bolts, and Cylinder head studs. I polished the crank and cleaned the pistons and oil ports, and re-measured everything. Installed it with the supplied arp assembly grease which I like quite a bit.



ARPs and Crank installed



Also, I scored a innovate wideband, greddy bcc, test pipe and midpipe from Bruce (thanks again!)

Now heres the best update, I called Cherry Turbo's 3 times since I've started, all about ideas for the ct-26, cost, best trim yada yada. Anyways, on thursday I had a friend drop off 2 of my 3 ct-26s I've aquired.

I really gotta hand it to Cherry Turbo's this guy was very nice and met me part way with the pick up.








As of March 23th the car is in the garage with the motor in, I towed the car to school in late February and pulled the 6mge, switched some parts necessary for the 7mgte (Oil pump and front sump pan, 5m/6m engine mounts and a few other misc parts) then towed it home. Also, new pressure plate, machined flywheel, and new clutch disc are at Eurodrive in Burlington getting all mated.
For brakes I changed to Wilwood 4 pots in the front, have yet to figure out the rear　

Alright, so pressure plate, clutch and flywheel are done.


And tires


On Rims:


Test fit of one rim (still need all the mounting hardware and I believe a 7-10mm spacer on front/rear




Front Dobinsons, with Agxs
Rear Dobinsons with Agxs




Scarey unfinished engine bay (has been worked on ALOT in the last week)


Interior (just finishing a heater set up then re-installing everything)


Finished Jim King Wiring harness, front Whiteline sway bar, mocking up the heater, trying to find a home for the oil filters (I have a dual oil filter relocation kit) and cooler.

Whats left, intercooler, piping, fix a small section of 2.5'' piping, custom made S pipe, engine bay wiring, put interior back together, run coolant/vac lines. wait for wilwoods, install, final clean up of small stuff.

1 really cool thing I bought was a Trasko Oil filter, I have yet to try it but when I do I'll keep you posted on how it is. These things are hella cool looking, and apparently do an amazing job. So after a few break in oil changes I'll be slapping this bad boy on as a secondary filter and change it probably every 10-15k (because I have a Toyota pre-filter)






Comes with everything you need and ran me about $90 bucks, with 9-10 bucks per replacement cartridge filter.


This is how I left it september of 2011, its still awaiting a move to London Ontario so I can work on it/store it for the winter




Because of the intercooler pipes being in a car that wasn't designed for pipes from the factory I had to remove the power steering cooler pipes, although not 100% necessary I still would like to have some sort of cooling option. Which worked well because my turbo inlet also was too big for the power steering reservior to fit, I moved the p/s reservior behind the grill for a dual purpose reservior, cooling and holidng fluid.

Very nice bro, my friends dad is a Supra guy and has one he built but it's got a 383 STROKER in it lol.

Love your build. Looks good Must be fun playing around with that car

Very Nice Keep the picks coming!!
