Project MK3 1987

Just to wanted share my build. It’s been around 3 years in the making. Car is American spec. Came already swapped with a 2jz gte. The car is being built here in Dubai. Engine work build being done by “kanzen motorsports” and carbon body kit/ interior cosmetic etc being done by “fos concepts”. Car should be ready this winter in under 2 months. Aim is 1300 whp single turbo. Redid the whole body paint gloss black and midnight purple engine bay and half roll cage. Build took a while mainly cause fos concepts which did the custom carbon bodykit/panels was quite packed and they took their sweet time doing it. They charged around “25k USD” for all the carbon work / full body paint/full body PPF/ custom premium Sony sound system/ alcantara interior and dash lots of carbon bits inside and rear seats full dry carbon and also the roll cage. Now I’ve kinda lost track with the engine build since I did multiple payments during these years. And I also bought a lot of oem parts myself from Canada/japan/Uk.
Gonna attach some pics. Don’t have many of the car since the garage is quite some distance from the state I live in.

Teins suspensions and willwood brake kit

Some of my fav parts that I got are the limited edition
HKS x BRIDGE seats and steering wheel.

For the rims I got the VOLK 21 A’s cost around or over 4k usd or smth back when I got them.

Featured in one of Larry Chen youtube video which he did on kanzen motorsports garage showing some gtrs and my car is there still in progress when the video was shot .

I have bunch of more pics but limit is 20 I guess.

Mk3 Driveshaft Fitment Question

https://preview.redd.it/d3iczd66cojh1.png?width=1600&format=png&auto=webp&s=6fae925cba65c4cbb4ad81ab940cb506dd2c165f

Currently searching for an OEM driveshaft for my 87 Supra. It's an NA, manual (W58), hardtop. Does anyone know if a driveshaft from a 90 Supra (same engine/transmission) would fit my car? They technically have different part numbers (37100-14590 for the 1987 and 37100-14630 for the 1990). But I don't know if there is any significant difference between the two that would make it not fit. (Photo is not mine, just for illustration)

A/C Condensor Fan

Has anyone here ever had to repair or replace the A/C condenser fan?

Does the A/C system need to be evacuated to remove the fan assembly? Looking at mine, it seems trapped between the condenser and the A/C lines, and I can’t see a way to get it out without moving one or the other.

Am I missing some clever way to snake it out?

Picture is obviously not mine, mine is still in the car... mocking me.

A/C Condenser Fan(s)

Working on getting the A/C going in my '88 Turbo and ran into a weird issue with the condenser fans.

I recently pulled a vacuum and recharged the system with R134a. It blew ice cold for about a day, but then stopped. I realized my condenser fans aren't kicking on at all, which likely caused the system to over-pressurize and vent the charge when sitting in traffic.

Here is where I'm at and what I need help with:

The Sensor: I found that the A/C water temp switch (the failsafe sensor on the bottom of the thermostat housing) is completely disconnected/bypassed. I'm going to wire in a new one to restore the safety cutoff. I think I have the right part # but seems oem is discontinued..

The Fans (The Weird Part): My car has a dual condenser fan setup. I couldn't get them to turn on through the female connector it was connected to, so I ran test leads directly from the 12v battery to the fan plugs.

Results: The top fan powered up strong. The bottom fan did absolutely nothing (completely dead).

Questions:

  1. Every time I search the forums or parts catalogs for an '88 Turbo, I can't find any mention of a dual condenser fan setup (vertical). Is this dual setup an aftermarket hack from a previous owner, or did some MK3s come with two front fans?

  2. Since the bottom fan is totally dead, what is the best route here? Should I just try to wire the single working top fan to run by itself, or do I need to rip this out and hunt down a true OEM single fan setup?

Any insight is appreciated.. it’s 90 degrees 20-50% humidity here daily 🤣

Hatch visor brand new brackets and clips~

Some time ago I got the original hatch visor from an auction, it came with the original brackets as well but they were deteriorated. Furthermore, the original brackets have tabs that go under the window trim, which by the age of many of our cars now would be impossible to insert as it would definitely crack the trim.

So I designed new brackets that don't need to be slid under the trim, in addition of redoing the side clips as well.

Here are some pictures of the work and finally I was able to attach the visor without any issue.

I can make the brackets and clips, should there be anyone who would need them.

Good news!

As MK3 Supra people, we seldom get good news regarding parts. It's usually, "I managed to find a 30-year-old OEM sensor in some junkyard."

Well, here's some good news: I just received a brand-new OEM Toyota fuel sending unit (PN 83320-80051) from a Toyota dealer for my 1987 Supra.

Better yet, it was cheaper than buying one from some random eBay seller for $500+, or gambling on another used 40-year-old unit. $316 out the door, $272 for the part ; $316 shipped to SoCal. I got it from Ourisman Toyota of Richmond, my local dealer wanted $500+ for it... but google.

Could I have repaired my original? Probably. But then I'm potentially repairing it again in 5, 10, or 15 years... and hoping the parts are still salvageable. Now it will be my son's problem in 30 years.

This sending unit is part of Toyota's A70 Supra GR Heritage Parts program:
Toyota GR Heritage Parts – A70 Supra

I'm posting this because some Toyota dealers don't even seem to realize these parts are available. It may take some calling around, and dealer pricing varies a lot, but you might be surprised by what Toyota can still get.

Hopefully this helps you guys.

🍺 Here's to my son cursing me out after I'm long gone.

Operation 1st Project car. 1991 mk3 supra 7mge auto

As the title says (self explanatory) just would like some guidance on where to start the structure is pretty rust free considering. Doing the front suspension at the moment and then what? Do I go for looks first then consider making some power? What’s the right way to go about things?

Power steering line

Having a really hard time taking this line off. I have been using a 17mm and 27mm wrench on each side however only the line moves back and forth. Is the 27mm side supposed to unthread to take out the line? I stopped myself incase I damaged it without a full understanding of how it’s even supposed to come loose. Any help would be appreciated!(model is 1989 turbocharged)

Removing hatch

I’m removing the rear hatch to replace it right now but I don’t know what to do with the wire harness back here. Do I have to disconnect it from everything and pull it through or is there a main connected I can unplug behind a panel?

87’ oil pump gear

This is my 87’ oil pump gear, I had the same issue with the old one and had just replaced it so I know it is new. Does anyone know of any aftermarket alternatives? Is it worth going to a machinist and having them make a new one out of a stronger metal?

Mock up v2

Found some key mounting points this time also made it look more aggressive I’m looking to add brackets on the bumper add ons to hold the outside of the diffuser. Also I’m planning on adding some more to the outside to make it look more aggressive, if yall have any ideas on a way to make this in terms of material/fabrication or looks wise let me know!

Send cams as is?

I know these are normal to happen for the 7M cams and all that. Can I take a 1000 grit very fine emery cloth without screwing up the oil pressure, or just send it as is?

3D Scans

Does anyone have a 3d scan for the mk3 that I can download or a link to a scan I can download?

How to remove glove box compartment

I want to remove the glove box to have access to the light and replace it.

I haven't seen other cars but i suppose the light should come from above, while mine comes from the side right next to the switch, and does not illuminate anything at all. Perhaps it had fallen down there somehow before i bought the car.
