Raul's 89 spg project and MEGASQUIRT II V3 tutorial

Ok guys, communists at saabcentral banned me, particulary jelous of me is moderator mathew. I will post all of my project info here so people can steal ideas, I will post more info in few weeks am about done with my saab project.

Raul’s ultimate SPG project. enough said!!!
I’ve spend some serious money on my project. I think my project deserves to be posted here so that others can use my information for their need.
I bought the car in great shape no rust sense I live in AZ I don’t have to worry about rust eating my project car at all. Whole car in running condition cost me $400, it has a lots of miles 270k, am amazed that engine block did not show that much ware. I also bought another Saab 1992 900s with bad transmission for $200. I took all the parts of the that car and junked the rust free body. That’s the best way to buy used parts for saab, it is cheaper in long run plus I get to use all the great stuff from 2.1L engine.
My project includes rebuilding everything. Eliminating heater and all the stupid extra stuff they put in these cars. I stripped the whole interior and will clean it all. I replaced the stupid leather seats with cloth ones. Replaced the automatic seat belts with manual ones. Engine management will be junked because am using Megasquirt V3. Took the whole dash off to eliminate crap that I don’t need.


Block 202
Pistons stock turbo 90+
2.1L head with cams, mild port job
tranny 91+
Turbo GT2860RS
3” V band downpipe
Megasquirt V3
Front mount IC
3” exhaust with magnaflow muffler
and much more…

Here is the photo of my 89 saab SPG project car:


Project is going very slow do to very hot temperatures here in AZ, am putting 2 hours a day into whole project. So far I have stripped the interior and engine bay, interior is ready for assembly.

Here you can see my Aero wheels from 1996 9000 turbo, and a 3” exhaust from my BMW that I will use including magnaflow muffler.



here is interior after I stripped it



here is interior after I put in washed carped and rest of the parts, I had to use tan carped sense the gray one that I had was torn.




Here is the Saab 900s year 1992 is beautiful shape that I bought for $200 for parts, it only needed transmission fixed and it could be very nice saab but I needed parts for my project so It had to go to junk jard. Rust free beautiful body, no dents at all, perfect paint, but it had to go. It is cheaper to buy a junk car for parts than go to junkyards always.
http://www.photodump.org/stored14/91donor.jpg



Donor 92 car gave me lots of great parts like this 2.1L exellent shape head with intake manifold and fuel rail


I decided to lap the valves and replace the stem seals, and also do mild port job, I did not want to do major port job because I don’t thing that it will make much difference, ports are smooth and pretty big.

http://www.photodump.org/stored14/21head.JPG


Here is the engine block stripped from my 89 spg, bore is just too good to believe, 270k miles with just minor wear, it is Swedish quality baby.
http://www.photodump.org/stored14/rauls270kblock.JPG

These are 90+ Saab pistons, they have improved skirt designed also oil ring relief design, while old pistons look like diesel pistons with longer skirt and very poor oil ring design where the only way the oil gets drained back is holes inside the piston. 90+ pistons don’t have holes in them that improved the strength. These piston look more like viggen pistons and that is new technology. I am using these.
http://www.photodump.org/stored14/90pis.jpg


I am using the best parts to build a very good transmission, it is simple, just use the transmission from 91 to 93 saab spg, it has all the improvements and that’s what I will use. I had a transmission go bad on me, these transmissions are not that strong we all know that but with extra care, good fluid and best parts we can make it to be just good for the job.

Here you can see the 91 gear vs 90 gear. Pitch of the gear teeth has changed, probably for strength, the syncro is bigger
http://www.photodump.org/stored14/gearcomparison.jpg

here are all the differences, forks are thinner and syncro collars are bigger and thinner, diff pan has a filter built in it with magnet, countershaft has a bigger bearing with sleeve, front cover has an bering to support the bigger loads.
http://www.photodump.org/stored14/gears.jpg

The forks, 91 vs 90
http://www.photodump.org/stored14/91vs90forks.JPG

you can see the bigger pinion is outside the tranny. I never had pinion go bad on me and I had som serious upgraded saabs. It is that people run out of oil and this bearing has to give.
http://www.photodump.org/stored14/pinions.JPG

most of the parts are not interchangeable, so you must pay attention. Transmission is very easy to get rebuilt with proper manual and if you got all the parts. I had all new syncros for newer tranny, this tranny will be nice.
http://www.photodump.org/stored14/rebuildingtranny.JPG

all done, using MTL red line viscosity is similar to what factory recommends, Never use thick oil on these ger boxex, syncros don’t like anything over 10w40. Use what factory recommends viscosity 10w30 and that is same as MTL.
http://www.photodump.org/stored14/trannys.jpg

http://www.photodump.org/stored14/readdytogo.JPG

This manifold is from 90+ spg, it does not have that annoying bump, it seems much more efficient free flowing, am using this

http://www.photodump.org/stored14/90mani.jpg

Transmission is done, engine block is done

http://www.photodump.org/stored14/enginepriject1.JPG

Engine is put on transmission, all the seals are replaced, new chain, new guides…blabla bla
http://www.photodump.org/stored14/engineproject2.JPG

Raul is no joke, I am serious Saab performance enthusiast and I have spent the money on best stuff. Innovative motorsports wideband 02 sensor, Megasquirt newest version and the best version V3, with stimulator. I had to buy an older laptop to use it exlusivly with megasquirt. IBM 390 is perfect, only $100 and it does the job. It has a nice serial port. Windows XP without any updates, only going to use it for my Saab. $900 spent on these 3 items, Raul is serious.
http://www.photodump.org/stored14/msandinnovative.JPG

I assembled the megasquirt by my self with the setup for hall effect ignition, bosch idle valve and much more.
http://www.photodump.org/stored14/msboardv3.JPG

Am planning on fitting this in my glove box, it is all ready and tested with the laptop and stimulator, Raul is no joke guys, I know my stuff.

http://www.photodump.org/stored14/msboardv32.JPG

Raul is no joke, a $1300 turbo kit is going on a $400 saab, GT2860RS with .64 ar turbine housing. Enough for 350 hp. A very efficient new design ball bearing turbo. It is already proven to be grat on a saab, Luke at saabrally.com had made 280hp with an RS but he has ford .63 turbine housing, it is a bit bigger but less efficient sense it is old school and GT is new school.
http://www.photodump.org/stored14/turbokitrauls.JPG

I already installed this very popular turbo on a B202 engine, I used two flanges and welded them together from inside and outside to make an adapter, oil feed line using AN4 and AN6 adaptors. Oil drain I used stock pipe, cut it weld a 16mm hose flange to it from my Nissan scrap parts, and then weld the other side of th eflango to a T3 oil feed flange, drilled the hole bigger. Water cooling is no problem, I already have banjo fittings for it. I will be the first person on the net that had installed this kind of turbo on a B202 SPG saab. There is another person but he has gt28r, a bit smaller.
http://www.photodump.org/stored14/raulsturbo1.jpg

Garrett GT line has revolutionized turbocharger performance and reduced turbo lag to virtually undetectable levels.
http://www.photodump.org/stored14/raulsturbo2.JPG

3” V band GT turbo adapter, very high flow, this will work nice. I will have nice 3” mandrel downpipe attached here
http://www.photodump.org/stored14/raulsturbo3.JPG
spacing is perfect, it almost sits in the same location that stock T3 sits.
http://www.photodump.org/stored14/raulsturbo4.JPG

here is the adapter T3 to T2, look at the oil drain pipe, I secured it to turbo support with a bolt, nice
http://www.photodump.org/stored14/T2flange.JPG

wastegate is no problem, I will have to use the T3 flange and the wastegate that came with GT.
http://www.photodump.org/stored14/wastegate1.JPG

I just saw this on SC. As much as I don't like some of the stuff you say, I've got to give you credit for what you're doing. It looks like its going to be great setup. Just don't lie about your shit this time, k? Also, I liked how you spoke in third person a few times, it made me laugh.
Keep us updated!

One thing I really like is how many pictures you have. Keep them coming.

I respond in very blunt way and to some people like you is not nice. Many people in europe are as I am, americans see that as very rude and abrasive. I never lied on the boards, find a lie, I would like to see it

Holy crap!

I remember when I got my first Saab seven years ago. And started using that shitty board called SaabNet.

You were on there and always stirring shit up.

You were a funny guy. Then they banned you.

ethan likes raul's car, but thinks he is an arrogant fuck.

ethan thinks raul has a small penis and that this bothers raul very much.

Zach thinks the red paint is due to Raul's hardcore engine building skillz... afterall, he said, "amish_geek thats your problem you talked to too many "tuners" and "tweakers" but you never talked to serious engine building folks."

Raul is no joke! He doesn't read hot rod magazines like the rest of us. Porting/Polishing and 3-angle valve grinds don't provide Raul with any performance improvements.

the c900 tranny:
"if you beat it, it will break..if you torque on it, it will break"

in the end

"look at it wrong, it will break"

kinda goes hand in hand with
"if it's a saab and it doesn't leak something, it's out of something"
