Saab Turbo Sierra
Yet another interesting engine conversion. The important bit here of course is that he's got a Saab 2.3 turbo engine configure for RWD.
Theres some Videos of it as well.

hmm , interesting , and it should be noted that a SAAB engine is one the best engines to modify being capable of lots of hp with out internal
modification reportedly +400 hp

I am considering building a class 10 grasstrack special with that engine in. It bolts straight onto several GM gearboxes, as these were what was used
on the later SAAB's.
For longitudinal installation it fits the manta/carlton 1800 gearbox, but this will be very marginal with the power. However the RWD 'box from
the late Omegas will also fit, and you can use an adaptor bellhousing (caterham/westy type one for a 16v XE) to fit a ford gearbox, and use a Quaife
dog 'box if you go to real extremes power wise.
My grasser would be transverse engined like the XE powered one in my photo archive on here, and I would use the F20 gearbox, with modified internals
from Steve Walford Motorsport (which would hopefully take the torque?!)

Any idea what they weigh? Also loads of cheap Volvo 2.3 and turdos about with 5 speed boxes or are they too heavy. I've got a 2ltr turbo 940 and
does pull well with very little lag.

theres a guy in lincoln building a saab engine grasser - its in a 205 shell with transverse box - he owns a garage in thorpe on the hill (feathers
garage) and dave is his name - does good for injector cleaning ( got his own machine)
re zetec : weight wise theyre the same as a pinto - depending on how you dress them .
if you read all of my posts youll find all the info you need , but if you want more info - send me a mail - i can give you details of engine mods etc

what does a fully dressed pinto engine weigh anyway.
Is the Saab a twin cam or single--head looks wide enough to be a twin.
Thanks Dale

Ahhhh, question for Dave Walker...........
What box is being used with the saab engine in the 205 grasser? Is it a GBZ jobbie or an F20 based one?
I am (intending straight after christmas) getting an uprated F20 built by Steve Walford (chap from Melton Club with the 2.9 VR6 engined Nova class 6,
which runs this 'box) and the maximum power that cam be put through this is unknown. He is removing 3rd 4th and 5th, and putting in wider gears
for first and second, obviously with better ratios (first is the same as the old second and second is about halfway between second and third).
The cost of doing this is a lot more reasonable than a GBZ jobbie (£500 vs nearly £3000), but then I cant imagine that the reliability will be as
good. No doubt fine with my 200hp vauxhall, but maybe not so good with the saab turbo????
Any opinions?

Nat,
The car that has been mentioned above (the SAAB turbo) is Dave Onions' ST7. He ran it this last season with the std fueling system and turbo
controlled by an Emerald ECU. It was making about 300bhp. It ran through the std (I think 9.3) Saab box. With the turbo the ratios are less critical.
It ate clutches!
I don't think I'm giving sectrets away but for this next season it will run a hybrid turbo, we have got the capacity out a fair bit,
bigger valves and a few other bits. It will probably be wound up to about 400bhp. I am currently doing some crank work and fitting a multiplate Tilton
cluch. He plans to retain the std box. In my opinion it will not be up to the job. If it isn't it will get a GBZ.
By the way a GBZ box with ratios is a little more than you may think. The Class 5 that will be at the show with one of my motors is fitted with a
brand new GBZ and it cost £4100 all up - the box that is!
I'm watching the Steve Walford thingy with interest. If he can do it at a sensible price then he will sell them. The Quaiffe kits for the F20
are about £1500 as you probably know and ratio choice isn't that good.

I'm not familiar with the GBZ and F20. What are their origins?

F20 , is a vauxhall astra/cavalier box , FWD - not sure about the GBZ - it must be tha saab box - but obviously based on the vauxhall since they based
the engine on 2 litre 16v .
And yeah , Dave onion , is the one with the grasser , ill be down there i the new year with some 480cc/min injectors that came from US for $70 per 10

Volvorsport - The GBZ 'box is a completely bespoke gearbox used in grasstrack cars, built (mainly) by Geoff Berrisford Engineering. It uses
Hewland internals and is 2 speed+ reverse (as far as I know, it used to be anyway!)
Dave Walker - I spoke to Steve Walford again yesterday, and I'm taking my spare F20 down to him on the 27th December. Apparently he already has
some gears machined, and has had a LOT of interest in the F20 kits!!
Mine will be a bit of a guinea pig as I race at the same club as him so any mucking about with the 'box will be easier! Steve doubted the
strength of the 'box with a highly boosted Saab turbo, but the proof would have to come form the pudding!!!
Merry Christmas all!

I'm not sure if I have misunderstood you - but the Saab engine pictured in the beginning of the thread is not based on a Opel/Vauxhall
engine. It is Saabs own engine.
I am building with the 2 litre version in my Locost and am using a gear box from an Omega 2,5 V6 -97 http://www.sonett7.net/engine.html

I think the SAAB engine was originally derived from the Triumph Dolomite Sprint engine.

Nobody said the SAAB engine was GM based!
The GEARBOX used in the SAAB is a GM gearbox, the F25 I believe as used in the V6 Vectra, which is why it will fit the Omega 'box in your
locost!
Yes, the SAAB engine was originally based on the Triumph 4 cyl but has evolved a long way since and now bears little/no relation to it.

Hi,I'm watching this topic with some interest as I drive a 2000 saab 93 coupe as my daily runner,the engine is superb.
I've driven a lot of cars in my time and the Saab is a very smooth capable and underestimated engine.
One of its best qualities is it's lack of turbo lag due to it being on low boost all of the time,hence the "low blow" tag.
It is nice and easy to get another 70 bhp just with a chip and air filter change,and good economy as well.
This has got to be a contender for anyone facying a zetec or vauxhall twin.
Dont know how quick they are in a locost but it soon gets to three figures in my road car,on a track of course!
Once I've finished a project why do I start another?

I mentioned the GM link , unfortunately i didnt look hard enough - isnt it about 94 onwards that Saab did base the 16v engine of the time on GM , but
with balancer shafts etc ?

That's right, it lost its Triumph heritage some years back.
Saab are now part of GM and lots of the product are the same.

I thought the gearbox link was well before this, all the 9000's that I have seen seem to use the vauxhall box. There seemed to be a big alloy
plate on the back of the saab engine to attach it to the gearbox.
