1989 Ford Probe GT project

For this who might be interested I figured I’d start a thread on my 89 PGT...

I originally bought this car back in 1999, it had a warped head due to being overheated. I repaired the car and got it back on the road. A few months later I sold the car to a friend for a down payment on a new home.…

Fast forward to a month ago (23 years later), my old friend messages me via FB and asks if I want to buy the car back- Of course I said yes because I had always regretted selling it.

History: Shortly after he bought the car (in 2000) he pulled the engine and had it rebuilt with Ross pistons, ported the head, had everything balanced, etc..He also bought a bunch of other parts (clutch, etc). Has the receipts from 2001
for everything.

He never put the car back together and it has sat in a heated garage for 22 years. I will be heading to MN (from WI) in a couple weeks to pick it up.

I plan on getting everything put back together and perform some minor modifications and post the progress here..

Here are a couple pictures of the car from yesterday- first time seeing sunlight in 22 years!

Got the power steering pump and bracket cleaned, treated the rust and sprayed black. Same with a few other brackets, the battery tray and engine mount plate.
Got the bumper stripped of parts and I am taking this and the hood to get painted. The hood has some minor rust under the paint in a few spots up front ..

Replaced the axle seals and installed the trans axle and bracket.

I have a new starter and alternator on order.

Ok guys need your help..I have one more bracket I haven’t found where it goes yet ( the engine was out of the car when I bought it). I know eventually it’ll find a home, but worried I need to get it installed while the engine is out...

Where does this bracket go?

Hey I just checked for you on my Probe GT. It looks a lot like the bracket for the pwr steering, but I think this one is a bit different. Could it be for the alternator? I was in a bit of a hurry so can check again at a later time…

Thanks if you could check..I am not sure it goes by the power steering pump, but could be wrong. Would be great if you could confirm..

It goes on the front of the block and bolts to the transmission (sits over the turbo bracket.

There is a bracket that does the same thing on the back of the block, there are a few variations of the bracket but it should look like or similar to this one:

Thanks for checking! I had previously missed the bracket under the intake that bolts to the trans…figure that one out last night..
Much appreciated!

Now that I got most everything installed on the engine with correct bolts I am going to go back and clean up that bolts (remove the rust)..

Now that I have a place for all the brackets I can finish getting everything put together on the engine. Installed a new starter and alternator. Got the exhaust manifold mounted and just about ready to bolt up the turbo- just need some new hoses for the coolant, oil and boost sensing lines. Getting closer to dropping this in the car!

If I get this engine in and everything running good, I will go all out on the chassis (all new brakes, rotors, calipers, tie rods, interior carpet....etc.etc..)..

Brad I am digging the build.
You need an exhaust manifold gasket heat shield to go with the gaskets, it's metal and protects the plug wires above and hoses below the manifold. It should sit between the head and manifold. If you have a used one that came with the engine just use a 3m scrub sponge to clean it and it will seal, I have 3sets of ported metal exhaust gaskets and have been swapping them / reusing them for almost 20years, I never have manifold leaks.

While you have the manifold off you should bolt it to the turbine housing/turbo, it's much easier to torque down off the car and the turbo is much easier to install when bolted to the manifold. (Push manifold over studs, install nuts, install support bracket bolt, connects lines and hoses).

Don't waste money on new calipers, just get front and rear rebuild kits, the front calipers have one seal and an accordion boot (full rebuild), the rear have a few more seals for the handbreak but they are easy to change.
You can rebuild all four calipers and change the sliders and sleeves for about 20$, spend the caliper money on a set of EBC red or yellow front pads or a set of four Portefield street performance front and rear pads, you will never have brake fade and your car will stop on a dime.

Thanks for catching that, Carnage! Got one on order...thanks for advice installing the turbo- I am working on replacing all the coolant and waste gate lines. I was looking at caliper rebuild kits (super cheap) and so I will likely go that route.

Installed the vacuum line “manifold” and vacuum lines..Pulled the hood off, which means I am getting real close to installing the engine!

Just a small update- winter about to break here and so now I can get the engine/trans wheeled over into the big garage (where the car is).

Got a new intake manifold decal today, looks real nice!

More to come real soon..

I don’t specifically- I usually google not just this part for an 89 Probe but I’ll try variations of MX6 and F2T.

How can you get me a link to this parts catalog?
the snap on catalog is for dealers i work at the parts department BUT there's another website that's free that we give to our customers that's sillier to this its repairlinkshop.com youll just have to make an account its free

Got the exhaust manifold heat shield on along with the turbocharger. Also got a box of parts from Rock Auto- its funny that the parts always show up in old azz boxes..you can tell they’ve been sitting on the shelf a long time waiting for me to buy them!

Hi Brad, more observations and advice (hope you don't mind).

Your #1 and #3 plug wires look kinda short, can't see the dissi side in the picture so it could just be the way the wires are ran.
Not sure what brand wires you are running, over the years I have tried many different brands of plug wire, Taylor 8mm, Excel 9mm, MSD low resistance and tons of factory replacement aftermarket wires. The best, most reliable, no issues, no bullshit wires you can run are the NGK blue factory replacement wires, on every F2T I ever owned no matter what fancy performance wires I ran (because of claims or color) the engines always ended up running used NGK blue wires I had kicking around.
The same with spark plugs, NGK V groove #7 (colder) or #6 (normal) spark plugs are the best plugs to run in these engines, I haven't tried as many different brands and types of plugs as I have wires on these engines because any time someone had an engine issue with an F2 and the plugs where different or new I would clean a set a set of old Vgrooves on the wire brush bench grinder, gap them and install them and the problem would go away. One 626lx auto we bought cheap, the guy did the air filter, plug wires, cap, rotor, plugs and oil service then the car wouldn't start in the rain or damp weather. I told him it had to be one or several of the new parts he put on that's causing the problem that wasn't there before, he said no those parts are new it must be something else. When we got the car to the shop I noticed he installed champion spark plugs so I threw them in the trash and installed 4 factory original (150+K miles) worn Vgrooves and the problem was solved so we sold the car.

If you look at my first picture in post #68 you will notice two black plastic clips that are screwed to the valve cover, these hold the spark plug wires to the valve cover and keep them from absorbing as much heat, melting or falling onto the manifold. If none came with the engine I might have a couple I can scrounge up at the shop.
The mazda part number is FE5010224, they are used on the mx3, mx6, 626, mpv, 323...
The screws are part number 99860-0512B


I spent a lot of time cleaning engine bolts for my 626GT build, I soaked them in apple cider vinegar to remove the rust, washed them and dried them, used eastwood degreaser/bolt blackening kit and diamond clear, they all rusted more than before I cleaned them. I have since been sand blasting them or cleaning them on the bench grinder and spraying them with Krylon (paint primer in one) matte black and matte clear spray paint, it's less work and actually lasts. Matte is thinner than gloss it doesn't effect the threading of bolts or pinch on the nut and bolt heads when torquing them, I had always been very careful to never get paint on threads but since working with the Krylon Matte spray paint and having no issues with up to 3coats (2black,1clear) I have been cleaning and coating the threads. 1 coat of gloss will gum up the threads and cause issues.
The very best thing you could use would be Cerakote, of all the fastener coatings available it seems to be many times more salt and chemical resistant and durable. But the cost and work involved using cerakote (even air cure) doesn't seem worth it, However I suspect that the instructions (or training) required to do a perfect job are to achieve perfect results. They state that to adhere properly parts must be blaster using 100% aluminum oxide or Garnet sand, these are both very expensive medias to sand blast with. Cerakote states in the technical data files that it has the highest adhesion rating possible (measure based on penetration depth of cross cut tape). So it would stand to reason that if the adhesion of POR15, powdercoat and spray paint is good to excellent when cleaning parts with a wire brush or affordable silica blast media than cerakote would adhere as well or better on the same metal finish.
Por15 has terrible adhesion and will only stick to properly prepped and etched metal surfaces, if you put the second coat on after the first coat cures (it cures fast in damp air) it's like painting it on plastic (won't stick to glass or plastic). Powdercoat can be used on new metal after only cleaning but doesn't adhere well, some spray paints can be used after simple degreasing and have good adhesion but have the weak finish and low chemical resistance of spray paint.
Eastwoods new blackening system has improved but is expensive and has a cure time of 3 to 4 weeks.
