Does anybody know if a rear sway bar from a "78-82" Cressi Wagon would fit on the X72? Addco lists parts available for that generation, but not mine. Looking at the EPC at work looks like the rear ends are almost identical from 1981-on.

Techno Toy Tuning custom panhard bar came in and it's gorgeous! Also it fits perfectly!
Image

Here it is installed (set to factory length at the moment, given that it's still stock height)
Image

Now I can lower it all I want and still have a centered axle. Also drove the car for the first time with the P-Type wheels on it. I'm running the stock 195/70/14's, which, when on the stock 5.5" wide snowflakes had lots of mushroom in the side wall, but now on the 7" wide P-Types it has a bit of stretch to it. It seriously feels like it has stiffer suspension on it. It rides firmer, is much more responsive to steering, and seems like it handles way better.
Pics of the car on P-Types will come tomorrow

Belts re-tightened. New hood struts installed so now it actually stays open without the rebar ghetto prop. Also it's leaking fuel from around the pulsation dampener, so I need to figure out what to do about that.

I was actually looking for a 7M bolt, but they are discontinued, and there aren't any 7M-powered cars in any local junk yards.

Got some banjo bolts from Mitchell's box of spare hardware. Harbor freight is out of their copper crush washer multi-packs till they get their shipment on Thursday, so I'll pick that up then. I also posted on CelicaSupra asking how to adapt A6 Supra seats to the X7 Cressi, and I got this super helpful response:

I had another photo I took somewhere.

First off lets paint this photo in your head. If you're sitting in the seat, The front left bolt hole closest to the driver's side lines up no problem. The other front bolt, near the shifter needs to have a bracket with a hole welded to the seat rail. So you can bolt in that side.

The two rears are easy. You get a piece of steel, run it straight across the factory bolt holes, mark where the holes are. Drill it out. Then bolt that to the floor, tack weld the two seat brackets onto the piece of steel. Then finalize the welding.

I did mine pretty quick. cause it was cold. And I eye balled the bracket closest to the shifter console. It's very easy. A lot of people made this too difficult when they would plan it. However, this didnt hit me until a member here with a white X7 posted his photos. So I give him credit for enlightening me. lol

So hopefully I can grab some steel this week and if Ju has the time to weld maybe get some new fancy seats put in this weekend.

Made my first order in piecing together suspension: MR2 rear shock inserts and Camaro rear shocks (both KYB AGX). My goal is to have this car lowered by 200DoD. Things left to order in the coming weeks:
T3 weld-on front coilovers
T3 camber plate bearing upper spring hats
T3 front camber plates
T3 front RCA's

Still not 100% sure on a rear spring solution. I really just need to get under the car and start measuring stuff. I have a couple options for adjustable spring perches, but I may end up going with just universal springs in a rate I want.


10/31/13
Leaky leaky leaky!
Image

Hefty hefty hefty!
Image

As you can see I replaced the FPD with a banjo bolt (thanks Mitchell). Hopefully this gets rid of the fuel leak.
I also bought some steel to make seat brackets to mount the Supra seats and some welding wire for Mitchell in exchange for using his welder :P

Oh yeah and I forgot to mention that Gearbox Magazine, a small online digital car mag, liked my build and decided to feature this thing.
Check it out!

Congrats on the write up! Mine still sits in pieces growling at me to finish her. I can see the forlorn look in her eyes everytime I walk by the kitchen window...

Shocks came in!
Image

Today I spent a solid 5 hours over at Mitchell's house figuring out how to fab up a bracket to let me use the Celica-Supra seats. We ended up getting the driver's seat in and its sah-weet!
Image

It's weird that the wagon has a better drivers' seat than the MR2. I still need to sort out the seatbelt situation, since I don't like how it's currently mounted (probably going to use an MR2 part if I can get one), and I also need to get the little pump-bulb thing hooked up so I can have functional lumbar support. ALSO I need to look into brown aerosol fabric paint/dye so I can brown-ify the red seat to sorta match the rest of the interior.

Friday night I picked up this thing.
Image
It's a 7M-GE OBX header for an MA70 Supra. The header itself should bolt on after a little grinding at the notch on the flange, but I think the downpipe will require some custom work, including adding the proper O2 sensor bung. No biggie, since the car will eventually be getting a custom exhaust anyway. I plan on cleaning up this piece, painting it, and wrapping it.
And before everybody get all "merr OBX is teh suxxorz merr", for the 5MGE you can pretty much do OBX or Pacesetter since that's all that's available. And this was $75. No complaints here.

Today I got under the rear and took some measurements to start figuring out a rear spring solution
This is with weight on the axle, just up on ramps.
9" spring height
5" diameter at the top where it meets the chassis
4" diameter at the bottom where it meets the axle
Want to lower around 2" - 2.5" and be MUCH much stiffer
Shock absorber length 16"

I also fixed the little squeeze ball thing for the inflatable lumbar support on the Supra seat. The bulb came from a friend who works for a company that sells used medical parts. He found it sitting in a warehouse somewhere and just gave it to me (free.99 for the win), and I happened to have a proper-sized hose laying around.
Image

It even stows under the seat for a pretty clean install. And it works great!

Took a spring out, measured it for real, and took it over to a friend's house to see if the bottom would fit on his spare AE86 axle. It doesn't. AE86 parts are out. I'm probably gonna grab some Volvo 5" diameter adjustable perches that should bolt up to the bumpstop mount on the chassis and work from there with some universal springs. Inexpensive and effective.

It's so beautiful.......should have....sent.....a poet......

I bought some Eibach circle track springs 9k springrate 5.5" OD (pn# 0950.550.0500) on my mx73. I cut about a coil out of mine an it sits pretty low, and probably has a slightly higher springrate as well. I'm not sure if the mx72 uses the same measurements out back as the mx73 though?

Wagons are solid axle, Sedans are IRS so everything is different.

So the stock Cressida seatbelt receiver is attached to the seat, whereas the Celica-Supra receiver is not. When I put the Supra seat in, I had to use an elongated bolt and sort of ghetto mount the Cressida receiver on a less-than-ideal spot on the Supra seat that was using a smaller bolt on an un-reinforced part of the seat frame. This also put the receiver at a very awkward angle that made it difficult to use.
Image

Luckily, there is a large 14mm bolt that holds the seat slide guide rail to the transmission tunnel that would be perfect for mounting a receiver to. And AW11 MR2's use a chassis mounted receiver that's pretty long. So I posted a WTB ad on MR2OC and got a hold of a guy parting out a rare tan interior AW11 and got one of the receivers for like $12 or something. It works flawlessly and looks like it came from the factory that way
Image

The only real mod I had to do was jumper the seatbelt warning light plug since the MR2 doesn't have one.
Image

Now to get another receiver for when I do the other side......

I'm aware that wagons are live axle, but I was not sure if they took a different diameter spring. If you can measure your outer diameter and figure out the approximate length you want/need, aftermarket springs are easy to come by!

It's 6" at the top, roughly 4.5" at the bottom. I'm going to be using 5" OD x 8.5" length springs with Volvo adjustable 5" perches that will bolt up where the bumpstops were.

Scored some finds at the junk yard
Less-cracked fan shroud
Image

Door molding in halfway decent shape
Image

My starter relay had at some point been replaced with a straight jumper wire (probably because they are retardedly expensive from Toyota), so I replaced that with a relay from the junk yard and have had zero starting issues ever since.
Image

Suspension work will begin later this month in all likelyhood, so stay tuned.

Everytime I am at the JY and there are Toyotas even close to the mid 80s, I grab relays. My normal yard doesn't charge me for them and like you said, they are wicked expensive from Toyota. Looking forward to the suspension work.

Well, that didn't last long. Last night the fan must have caught part of the shroud, destroying the shroud and breaking a blade on the fan. Time to make an e-fan setup. Probably gonna get some universal thermostat controller from Summit and some e-fans off something in the junk yard that I can ghetto mount.

Yesterday I picked up a Volvo electric fan (same great fan motor as the Taurus that everybody and their brother uses, but thinner and with a easy-to-grab relay box) and the front struts off a junked Cressida. Tonight I began the process of tearing them down and getting them ready for the coilover conversion.

First I set up some heat in the garage so I didn't freeze
Image

Complete stock strut:
Image

Spring removed
Image

Here's the stock-sized Sensatrac shock that came out next to the SW20 MR2's KYB AGX (for the MR2 rear) that will be going in.
The stock shock has a body length of 15.5", whereas the MR2 shock is 14 3/8" long, so the housings will need to be shortened 1 1/8". Also, the gland nuts that come with the MR2 shocks are a much coarser thread than the Cressida ones, so I'm going to have to reuse those.
Image

Here's the housings with the stock spring seats removed. I didn't bother grinding the weld flat since I'll probably be removing that section of the tube to shorten it, so as to keep the brake line tabs in the same place.
