Anyone ever put an 2.3Turbo Saab engine in a sierra? If so how difficult was the conversion? I want to build a turbo powered sierra but would like to stay away from the usual pinto turbo zetec turbo cosworth turbo conversions? I'm open to suggestion aswell saab was just a quick idea, as ive seen good powered saab aeros etc that seem to be reliable and can take good power?
Thanks
Chris

Saab is one avenue although the electrics may take a bit of work. I believe PPC have done gown this route with a MkII Escort . CA18DET is another potential candidate. Quite a few Rover V8 conversions have been done over the years, although I would be tempted to whack a Duratec into a Sierra these days .

Volvo 740/940 probably easier, already the right way round with a RWD gear box on it, get a late one with an M90 gearbox and the box will take a curse word load of abuse, the old 8v turbo is also mighty strong and easy to tune.
also depends what Sierra you start with, if it's a 2.9 V6 the 24v granny engine is an easy and worthwhile swop.

Volvo engine sounds like a good choice to be fair, don't fancy the 24v v6 route

Had a lot of fun with 4, 5 and 6 pot Volvo engines, they certainly take the abuse too. Both Volvo and Saab engines can take a lot of boost before needing anything more than bolt on upgrades. You can even bung a Ford ST/RS rocker cover on the Volvo 5 pots too! Get it done!

After having a quick read up on 940/740's I'm starting to think its definitely the way forward, which is the better engine, 8v? 16v? redblock? whiteblock?...

8v red block is tougher and cheaper and can take lots and lots of extra boost, 5 pots have more poke to start with but cost more to tune and are not as strong (still pretty strong though), obviously the 5 pot is also longer so will need more space. using the 16v head on an 8v redblock you can build a 500bhp boost monster so it really depends on what you want to achieve, if you "just" want Cossy performance you can get that with a 8v red block, an MBC and a boost gauge.

if you wanna go saab route or similer then get a ecu setup like mega squirt etc,. Saab uses the Trionic 5 management system, and its such a good system it is commonly removed and fitted to non Saab engines. Its a fantastic system and can be tuned and altered at home. Thats why the Saab B234 is such a cheap and easy engine to tune. There should be plenty of info on the wiring front as many Vauxhall boys fit this engine. The only problem is trying to find a box that can take the torque. The Saab has so much torque in standard tune even the Omega box is "alledgedly" unable to handle it.

Wiring a t5 Saab ecu is pretty simple , the stumbling block is the sump as its front well and sits at an angle . I do steel sump kits with a laser cut 5mm flange that would sort you out but as said the early volvo would be a simpler swap in a sierra . In terms of tuning the Saab is well catered for with a few different ways of Hooking up to the ecu with either a USB/bdm for around £40 or the can USB lead at around £100 . The Saab system has the best knock control system I've seen on an oe ecu with individual Cyl knock count and ignition trim so can protect itself from det once you start pushing the power levels . Never had a det related failure running 500+ hp for many years .

Thanks for the info... so ideally 8v with a 16v head is the way to go? Just trying to work out everything thats going to be needed then attack it in one go so to speak

16v head on 8v block is doable with mostly stock parts and some machined pistons, not needed though unless you want uber power, most of the lads don't do much more than a bigger 19t turbo, different cam, chipped ECU, boost controller and sometimes bigger injectors, with a good exhaust that should be good for a reliable and drivable 250bhp. I'm no expert though, its only what i learned while I had mine, besy get ob to turbo bricks or the Uk volvo forum for full details and parts lists.
Stock 8v turbo with an MBC and boost gauge will run 190-200bhp though with no problems, mine ran 11psi for two years with no issues in daily use.

Thanks again for the info again, a few more questions!
1. stock 8v turbo, how much boost can it run? how much power? (with full exhaust fmic and mbc bigger injectors) 2. stock 8v turbo,with 16v head, how much boost can it run? how much power? (with full exhaust fmic and mbc bigger injectors)

I don't know for sure, I have seen the guys on the volvo forums claiming over 20psi on stock internals. option 1 should run 250bhp+ and option 2 is just loads, 400bhp+ but a 16v head conversion will end up costing about 3k for parts and to have the pistons machined to clear the valves, not bad for the power but if you go that far you have to do the rest of the car to match so might as well just start with a cossie in the first place.
You'll get more precise answers on the volvo forums, i just found this stuff out while deciding what to do with my engine and box, but as it turned out i ended up leaving it in the car and using it as a daily.

I think I'm just gonna stick with the 8v turbo to start with, what kind of torque figures do these engines produce??

Anyone know the weight and length of the 5 pot?
I can feel a cunning plan brewing... :-)

Just joined the UK Volvo forum so will hopefully get the answers i want from the guys over there, and will update with any info i find useful for others that don't already know. Cheers for your help so far..

2.0 Cosworth with a T3 is such a perfect engine for the Sierra. They go so fast, the power is easy and parts are plentiful. Why the Saab/Volvo other? A Sierra with a turbo Cossie engine is quick and very simple.
The YouTube vid above says 260HP. Cossie engine with a mild setup and injectors does 300HP.
