1989 9000 turbo Rebuild

667 Views 33 Replies 9 Participants Last post by  kamiel
Grandparents have had it sitting for 15+ years and said the trans (auto) and turbo need to be replaced. I want to get it running again and I think it would be a good experience for somebody that doesn't know a lot about cars. How should I go about this? Am I getting myself into deep sh**?

Find a good early 4HP18 in 2023 is going to be tough. I'd start there before committing.

Depends. ;)

First you should take a look at the car, ideally together with someone experienced who can tell you if the trans and turbo (and other parts too) really needed to be replaced. Keep in mind that the supply on spare parts is a) limited and b) sometimes quite expensive and c) hard to retrieve and that you d) are not likely to get back whatever you had invested financialwise before.

If your companion says "yes, possible" and your mind, heart, time and wallet says "okay" this could be the beginning of a beautiful friendship.

My grandparents let me know its gonna be a money-pit. I have some friends and family that are willing to help and appraise the car for me. I really just want to get some 'Saab Gurus' opinions on this. Would an engine swap be ideal IF I can't find parts?

Yess .. imo you are.
I've owned a couple of 89's including an Autobox version. .. when these were New.
Seriously Not Recommended.
Saab were V unreliable cars (legendary even) They did get incrementally more trustworthy as their production years progressed and finally in '97/'98...
approached passable Reliability standards.
Auto box of '89 was Junk ! not worth the trouble to rebuild. Turbo units are easily found. Don't worry about that bit.
Far better to source a 97/98 wrecker autobox and deal with the slight bellhousing adaptation differences .

However 15 yrs IS a loong time. Parts unused... tend to rust together.

Its been garage kept, (Should've mentioned that) but from my very untrained eye, the car and bay look/seem clean. Should I focus my attention somewhere else instead?

The question is: do you really want to restore the car and keep it regardless of the difficulties which may occur?

If you need a daily driver which is easy and cheap to maintain there sure are other vehicles out there, as any vehicle sitting for 15+ years is usually spelling trouble when trying to bring it back on the road.

Give it a deep thought, weigh the pro and cons of this project. Reading through the many posts regarding the 9000 may give you some help with your decision.

Thank you again. I'm just trying to gather opinions and see what you guys have been through. This project is most likely not falling through but I just wanted a reference to fall back on, if that makes any sense.
There are tons of options here. I wouldn't relegate your thoughts to one approach vs another until you have gathered some facts.

The 4HP18 was not popular in North America but was in a lot of cars in Europe... So sourcing one from Europe could be an option.

You will probably have a tough time finding a 5-speed transmission simply due to age, but it's not impossible, and the F25 is pretty reliable. I have manual-swapped several early 9000s and, regardless of what Debbie Downer has to say a manual, early 9000 is a great car.

You could swap a later engine and manual or automatic transmission into it. You could go find an Alfa 164 and swap its engine and transmission in.

Lots of options. I would explore them all. Early 9000s are getting very hard to find, which IMO makes this a fun project. But it could also be costly. You won't know til you start looking around. Maybe you will find someone parting out a running car that has rusted beyond repair. Weird thing about weird cars is that it's mostly about being in the right place at the right time.

Pictures needed!

If it is in very good condition rust and wear wise for the metalwork, then by all means go for it! !985 to 1998 perhaps tells you that these were very well designed, and reliable, cars. Performance versions consume lots of parts, as is true with all such cars. I knew many people with new early 9ks with auto boxes, and the only ones running into problems this side of 200k were totally neglected, running > 300hp on track, or towing something bigger than the car itself.

Early on figure out the state of the engine, get it running, and appraise the transmission. If that is the biggie, it is not too hard to solve with a replacement in the worst case, even if souced from Europe.

Modern classic, and very retro cool, get it back on the road.

Dropping the Busso (Arese) V6 in a 9000...sounds like a task for you, jvan. ;)

I had a 164Q for many years and enjoyed that car thoroughly, but TBH, while the Busso is a wonderful sounding engine, it doesn't offer anything in practice over the B234R. Frankly, the magic combo would be a B234R in a 164... Italian styling, independent suspension, and a tank motor under the hood. :D I don't think I would willingly put that V6 motor in anything anymore - that timing belt was a nightmare.



But, if you're asking about engine swaps it's one we know fits (and even comes with a 4HP18!).

@fixedherupper - that's a great looking 9000 from the outside. Personally, I would take pains to fix it up. If you could find a 1996+ 9000 that someone was parting out, you could plop the entire drivetrain it with relatively little hassle. The Trionic 5 fuel injection swap is very well documented at this point, and you'd end up with a pretty cool car I'd say. I'd drive it!

This is NOT a weekend project - this is something who knows what they're doing could spend a month on. As a first project, anticipate many months unless you have a latent super power. But would be fun, IMO.

Holy SH** thats beautiful. Hard work pays off. Thanks again for replying. I'm doing more and more research everyday and this forum is super helpful.

Yeah, them Alfas were always being nasty pieces of work. Apart from me thinking that the 164 looks better than a Saab the only reason for dropping the Busso into a 9000 would be exclusively for the sound and leave the rest to an Alfa specialist. 😁

Side note: I'm still searching for the pic of a Scirocco II with the rear lights of the 164. Looked pretty sharp.

What jvan said...I have seen cars stowed away for years in far worse condition (=exhumation...). I'd say get it out of the garage (do not attempt to start the engine!), clean it carefully and undertake a close inspection for rust and decay before deciding the next steps.

It would be interesting to know what's wrong with the transmission. As I mentioned, that ZF box was not popular here and almost nobody knew how to work on them. As it turns out, they are remarkably user-serviceable and there are a few common sources for problems. It could just need a governor or the accumulator springs are broken or the pressure control valve is worn. I wonder if the later transmissions use the same parts.... they are both the same model, but that doesn't mean they're the same on the inside. ;)

From what my grandma knows, its just 'something' with the transmission. My grandpa passed away so I don't have any inside information on that. I was thinking about doing basic maintenance (spark plugs, oil, fuel pump, etc) and have a family member check it out from there. I'm to scared to do that though thinking I'm gonna F something up.
