Hi guys, I recently started owning classics but always had a soft spot for them or hard which ever way you want to look at it :lol: when, I had the fortunate experience of my nose being rubbed into the ground back in 93 by a person driving an enduro (the white one from Canberra Australia which is all over the net, Mark I believe is his name). I owned a 5lt V8 at the time, turning the corner 3500rpm I let go of the clutch and off we went and so I thought ;oops:. From 3rd gear into 4th, he was now about 500mts in front and pulling away like I was standing still bouncing around the corner flat as a pancake.......... goooooooone! :eek: Thank you Mark for that "fateful sunny day in Canberra on a lonely old back road" I have never forgotten your car or that day, as it has made me the Saab man I am today ;)......which leads me to my question.....Q: I am building a race car all rounder (street sprints, hill climbs, drags etc) from a 87 2dr and converting from front wheel drive to rear with a Nissan rb30 5 sp, adjustable 4 bar rear with coil overs, watts linkage and torque bar (please! no why are you doing this Q, I have already started) I would like to know has any one done or seen similar?. I am not having dramas but all ideas are good ideas and there might be something I have over looked!.......I have pics if interested and by the way I do own a 900i stock daily driver also so please, I dont butcher everything :cheesy:

I'm sure there are a few out there, but I can't point you to one. Put up some photos! You can get an account at saabphotos.com and add them to your thread.

I was considering doing this with my '85 since it has some issues that prevent me from wanting to fix it up, such as an entire rear quarter that was replaced but doesn't quite align properly with the hatch (it's close, but if you spend time restoring something you've got to be picky). I was thinking about making it mid-engine and transplanting the whole Saab engine/transmission just behind the driver/passenger seat. I'm curious to see what your plans are in more detail!

i have also seen one done to rwd by using the front chassis/suspension/engine etc fitted into the back.
theres another one on youtube that has been done similar to what you want, but the tailshaft is inside the car :eek:
you could just stay with the saab engine, they are a lot stronger than what you may think, and i have seen some huge power made from them. RB30 is going to be a lot heavier so your weight distribution will also need to be revised.
if anything i would go with an SR20 because its lighter and you will have more room in the engine bay.

EDIT:
oh and welcome! :cheesy:

Welcome.

This is one I remember; it is a 9-3 which the guy basically cut the boot out of and welded in the rear floor pan form a BMW, complete with supension and linkages:





And here fitted:

thank you for the warm welcome and the pics of the rear not yet there but EXCELLANT!..........this is the sort of thing Im after.
I'm at the engine in and box cross member stage, which is incorporated in the extra bracing that's also going in then the tunnel for the tail shaft then on to the rear and so on.......

As for motor power, I never dispute an engines capabilities but to coin a drag racers phrase "there is no substitute for CC's" and if you don't believe me bore and stroke your 2lt to 2.8 or 3, let me know how they match oh and don't forget to dyno them both. Also you never see a 2lt pro stock or top fuel dragster...
I want an all rounder and a front wheel drive just isn't flexible enough, 100% anti squat for the drags one weekend, the next for hill climbs, oval track, another day skid pans etc etc (not that I have the cash for that much fun:cry:).........and for the extra weight ummmmm, you do know the box in the Saab is under the motor and the Nissan is behind. Regardless of the extra 2 cylinders the weight distribution is far better and also I have put the motor 154mm inside the middle clip, again better weight distribution (also it was previously an auto so same weight, I did my home work) and sadly also the car with the factory springs still sits too high they have not "taken" the weight so this reaffirms my statements, sorry this arrangement IS far superior!

Seriously, I also own a 87 Pontiac Trans Am twin turbo 540 big block. This car is for salt lake racing once a year for five days "speed week" (look it up, "Bonneville" down under). It is too expensive and too much hp to be a toy elsewhere and, I WANT A TOY! so hence the Saab, its my fun car (its the way the makers intended)......
Anyway this is a dry run. I have a rb25 twin turbo sitting and waiting (500+hp, not exactly sure hasn't been dyno yet) but I want to run mild power for now (200) to make sure I have over engineered every-thing... will keep regular posts as I work on it all the time and I do appreciate the interest guys.....

cheers........

(here's those pics as promised........)
this is first stage, strip measure and cut




second, lining up for the engine plate position (which turns out to be the old engine mount spots, too easy)





the steering rack in the picture is out of a 84 Commodore (Vauxhall) using the column as well, non-power rack and has the same thread on the tie rods (screw off GM and on with the saab ones) and mounting points are so close matched almost uncanny oh and 10mm longer tie-rods but were trimmed, now PERFECT!



the engine with the box on is actually, another 12cm in the car (biggest hickup so far is the exhasust more cutting had to be done also) compared to the above photo.

don't have the photos of the box in yet will post later.......for now its bracing laterally in 4 places (100 x 75 x 3mm box with bend for tail shaft) before the tunnel starts getting cut. 1st bracing is for the firewall and roll-cage points, 2nd for gearbox mount and front seat rail, 3rd for tail shaft safety loop and rear seat rail, 4th for seat belt 4 bar and middle cage mounts...and all will be K framed also. The rear section will be explained later as I am sorting out the suspension in the meantime....keep you posted

I dont know why but the pics I posted are still not there, so a brief description of the project thus far........

*stripped the car to bare roller, measured for engine and trans
*cut- fire wall, front brace under floor pan also some
tunnel/backbone (600 x 600 fire wall and 200w x 800 floor pan)
*old power steering rack replaced with constant ratio manual steer
and column from same (Australia has right hand drive)
*engine in, original mounts on car and motor will be utilized, places
motor 150mm inside the cab and front 2 cylinders on top of front
wheels
*seat rail/brace removed (inside car)
*gearbox in/on, mount lined up for bracing/mounting point

that's it so far and all has taken 5 weekends.......

the next stage is to brace the front and middle clips (especially the middle, flexing like buggery now since half the backbone and firewall is gone) with 100 x 75 x 3mm box and put in a new firewall...

Only hiccup was the extractors they need to be modified, closer to the block (hit the control arm) and longer before the bend under the car which will exit on the left in front of the back wheel....

I never mentioned another reason for this project, my mates race cars, one has a PBR club-man 30000au spent another, Holden (Vauxhall) Gemini 9000au spent and the other has a Mercedes 190e 11000 spent, they all race together. Now it comes to me without the rb25 setup I have on the side, I have a bet with my mates (1500 dollars collectively) that this project will cost no more than......1500 collectively! as proof to them that a race car can be cheep, my labour is not included............

So Grand total thus far for the project is : $0.00au

Saab cost $250, sold parts off it (interior, wipers, dash etc)....total $280
Holden/Nissan donor car cost $350, sold parts (body panels, wheels interior etc)......total $340

also with the stuff I have around the house from old projects (seat, harness, wheels etc) I cant see it going over budget so....... get ya wallet out fellas!
got to luv (am I able to mention the major internet auction site :nono;) e...!

So why use a Saab chassis and not something better suited to the job. So far, I can see you've taken a front wheel drive Saab with a Saab engine. Removed the Saab engine and you are in the process of converting it to rear wheel drive. You're intending to remove the Saab suspension and replace that as well. :roll:

Just buy a RWD car? I'm probably missing the point, but why bother? I like the Saab as it is. I suppose it's an interesting engineering exercise...

one didn't miss but sexy is not what I would have used though, unique maybe... and here you go to help catch the point....

WOW this is great! doing this kind of mod must be an everyday thing for most of you. Sorry I,m a new enthusiast to Saab's as a vehicle I didnt realise how advanced you Saab guys are. I am just a humble person I thought I would teach myself some techniques in automotive, things like race chassis and space frame design, steering and suspension, sheet body engineering etc etc......and also you know that boring stuff that goes along with it things like power-train and vehicle dynamics, the effects of chassis flexibility on roll etc, weight reduction techniques, aerodynamics and down-force effects...........OH please forgive my manners I must be waffling on this must be revision for most of you......:roll:

point is I chose Saab for the same reason this website exists and has members.....I LIKE THEM!........and why do it?...........BECAUSE I CAN! :cool:

thanks guys any kind of interest is appreciated!

(you know some people in there retirement don't have anything better to do except criticises others for having a go :evil: )

FOOD FOR THOUGHT! most appreciate constructive criticism not uneducated opinions

of all people, saab owners should understand. we like things that are unique. this car that he is building will be the only one of its kind. it's fun! no, it's not really a saab anymore. but it'll be darn cool!! :cheesy:
