This is mostly directed towards doward, vortex, techsmurf and anyone else who is doing or has done a turbo setup.

i don't have time spring break and will be doing the stuff I've already posted and mentioned, but.... it appears as though there's a complete saab 9000 turbo setup that I can get my hands on, turbo, intercooler, everything. there's a good chance i might even be able to get 2 complete saab turbo systems.

twin turbo?

i'm thinking i'll have time this summer to work on it and perhaps even a little time the second half this semester. welder, pipe bender, milling machine, shop tools, etc. are all available to use, so it's not a question of having the equipment to work on it. what do you guys think? what would be the hardest part of converting it? just trying to plan some things in advance. it'll be a drawn out project if i do it, but any info you can give me or pics would be great.

 

what size/code are them turbos?

We have only seen one twin turbo mpfi, and it was in a datusn 510. Think he had 2 t25's on it?

 

i think at first they were T25's, and then he upgraded them to T3's. I think T3 Super 60's IIRC.

 

They're T25's off a 90 and 91 saab 9000. cost for me is free on one, possibly both, but likely only the one off the 91.

 

techsmurf, i just found the pics you posted about your turbo setup. would keeping the same exhaust manifolds, but creating a y-pipe that curved foward instead of straight back possibly be a good way of going from the manifold to the turbo on a single turbo setup? i'm sadly going off memory of the engine bay and my car is 800 miles away so i can't look at it. just trying to think of ideas to make it as inexpensive and *cough* simple *cough* as possible.

 

inexpensive
simple
turbo

Dont not belong in the same paragraph

 

lol. yeah, perhaps i should insert the term relatively. cost of turbo system out of the saab including ducting, intercooler, pressure sensors, turbo, etc. is $0.

other random parts can be gotten for the same price. (father owns a saab repair shop and has a couple of parts cars. some parts aren't worth his time to take off and sell, and he's not interested in trying to put that turbo on something else.)

cost of manufacturing things...varies depending on what i can find laying around the house/barn/shop.

paying someone else to manufacture...now what's the fun in that???

relatively simple being that i'll have about 3 weeks at the beginning of the summer with nothing or extremely little to do while i wait to get transfered to whatever naval station i am getting sent to (find out in 2 weeks.)

perhaps the best question to ask would be: 3 weeks available and $200 sound like it could be done? or more money or more time?

 

probably not in 3 weeks, you WILL run into hurdles.

The biggest hurdle will probably be the headers, since on these V6 the serpentine belt will get in the way alot of times.

BTW, where in VA are you? I have a MIG welder and im in Virginia Beach.

 

I expect to run into hurdles. But i'll have nothing to do cept for hunt down parts with my truck.

VMI in Lexington. 3-4 hours depending on speed and traffic.

I have the mechanical engineering machine shop here plus my roommate's uncle's automotive shop in Staunton to use.

 

I figure if I can get most of it at least manufactured, i could get the rest of it tuned once i get to my station in my off duty time.

 

Negatory.. this is how Doward did things, if you want to go that route talk to him. My system is only as ghetto as it is because someone else wanted to do it for me at no cost with parts I didn't want to keep anyway (hard to argue).. reccomend full custom manifolds.

 

thanks techsmurf, that's one of the biggest questions i had.:hail: :hail:

 

Well, I've officially been given the entire turbo system out of the 91 saab 9000 with the T25 turbo. Going to start making nice custom exhaust manifolds. It's just going to be a side project, so don't be expecting much progress. When I actually have something more to post on it, I'll do that with some pics. Don't hold your breath cause I certainly have plenty of other things going on. Some day perhaps there will be an affordable turbo kit for our beautiful cars.
:lala:

 

2.0 or 2.3? Is the turbocharger undersized from the factory? What is the redline rpm of the car? You obviously haven't done alot of research into the physics involved here.. now would be a good time to do so before you do this and you find out that the turbo's too small and you *lose* power before redline. from the looks of things, you seem to believe that a turbo is a turbo.. this is simply *not* the case.

 

2.3, yes it will lose power before redline, no i do not use it for drag racing so i won't be going to redline, no a turbo is not simply just a turbo, yes i have done research, yes it will give me gains in the power band i am looking for. for a proper turbo system, i would need either a larger turbo or else do a twin turbo system with extra exhaust going out the wastegate. i don't have a larger turbo, or a pair of turbos, so this won't be happening. just have the one T25 available, and looking at everything it will give me extra power in the range of use i'd want it for. this isn't the first time the idea has come up and been discussed between myself and a master technician who knows everything about the saab turbo system. this just happens to be the first time a system has become available and i was just looking for general problems experienced by people who have tried putting one in.

the original thought when first posting was that if i could get a set of them, it would be nice to attempt getting a full twin turbo setup. if not, the single would be able to give me extra power for the rpm's i'd want it for. the three weeks at the end of the semester would be to get everything in and start getting it to work. there would have been a lot of prep time leading up to those 3 weeks, and would be work after the 3 weeks, however the plumbing would at least be done.

sorry if you think i'm an idiot and i won't bother posting any more on the subject unless i actually decide to do it and get something that somebody may think is worth something.

 

For twin, they'd be way too big, 2.0 or 2.3...

Assuming the saab redlines at 6000 rpm or higher, the turbo should match up to the specs of an undersized factory turbo, and work rather well on a 2.8 .5l difference isn't much. Good luck with it. It'll certainly spool alot earlier than mine does
