saab 9-3 turbo aero viggen engine into vectra

[bowie_277]

well ive been thinking for a while now wether to buy a saab 9-3 turbo engine and put it in my veccy ive seen it done once before on another forum and he said it goes harder than the astra sri's just want to get some oppinions on the idea from any one ?? the engine is similar to the opel vectra 4cyl engines and i was wondering if the engine would fit with my gearbox or would the saabs gearbox fit into the vectra

That's quite a big effort modification project to do, if you really want to do it 1st thing I'd suggest is work out the budget involved and then see if it's worth just modifying the existing engine to achieve a similar result or if it's more cost effective/less effort to install the SAAB engine instead...

Power output of any of those can be modified anyway, so if the SAAB's engine has a higher output than the Opel, I'm sure the Opel can be modified to similar and/or greater output, so I wouldn't consider using the SAAB engine if it was just based on that part of it.

If you do choose to modify the existing engine, you can also consider other forced induction options eg: supercharging as there are now kits for these or you could stick to n/a and modify capacity (stroke) the engine and adopt higher performance internals...

Either way you should also consider the rest of the drivetrain as well, if you increase power appreciably you'll need to look at the trans and other associated mechanicals to make sure they cope with the added stress, you need to also address cooling and brakes to make sure the whole package remains reliable and safe...also be aware that modification/s of this type will render the vehicle completely unroadworthy unless you go to great lengths to have it all engineer certified to avoid being pulled off the road in the event of being issued a 'canary'...

Unless it becomes a proper 'street machine type' project or 2nd/3rd car it's all these considerations and more that usually force people to buy something else instead that already has all of what you want from factory especially if it's an everyday car, then just tinker with that :)

Yep, O/S for complete bolt on ready made kits...

Otherwise there are plenty of local tuners/tuner shops that will do a 'bespoke' or custom job just for your particular application but be advised either way is going to be an expensive excercise and usually ends up being an ongoing thing as many issues usually arise with such modifications, I know being there and done that so many times myself in the past...

See how you go with more research on the subject and hope it all works out one way or the other :)

wont work with the aussie 2.2L

and wraith, glenn is putting out close to 300kw atw through std gb, could get away with std dif to, tho lsd would make it more drivable.
i agree with sticking with the std engine, you can do enough to them.

auzvectra used the veccy 2.2L block on his astra turbo and made a butt load of power too....
