Why not use an engine from a 2.3 9-5 instead? Isn't that the same engine?

Thumbs up

Anyone have the specs on the differences between the viggen engine and the standard 2.0L? I have a 01 9-3 SE and that auto dismantler isn't too far from where I live. It would be interesting to get a viggen engine as well as a viggen IC. (assuming they aren't charging insanely high prices for the parts)

My understanding is that the Viggen's 2.3 and the 9000 Aero and 9.5 are ALMOST the same. For one the timing cover and perhaps a few other external bits are different. Internally not all 2.3s are the same, with differences in oil pumps, pistons, etc.

You'll need a new ECU, IC and hoses but I would look to aftermarket upgrades.

If you can wait and buy Dan's engine (snow4_1man) do so. I'd trust him more than a used parts guy

Also the dismantlers' engine sure won't be cheap.

The 9000 Aero and cse engines are the stoutest. For a t7 2.3 I think u just need the ecu.

No need to upgrade to the 2.3.. Just keep the 2.0 and put a turbo on it for what you would spend on the engine swap and you will gain much more.

If you've got an 01 se, you have the same IC as the viggen already.

This would all be taking place much later in the future. I have yet to even order my turbo back. I just thought it would be a cool project to do an engine swap, I have no idea if I'm going to do it or not. I don't have the means to do it mechanically and definetly don't have the money at the moment (go college).

I've wondered a lot about this... it seems like owners jump to the 2.3 motor, but all of the SRS BSNS hi-po saabs were 2.0s. The Clarion 540hp T16 4x4, and Per Eklund's 750hp pike's peak viggen were both 2.0. What's up with that?

I really like the point that Nick is making about buying a bigger turbo and keeping the 2.0!

Why spend the money and time when buying a bigger turbo is a simpler and probably more cost effective way to do it?

15% larger engine is not much. You do gain a different power curve.

But bang for the buck. ( If your engine is fine.. If it was blown and ruined the crank then different game.) Either way engine size isn't the limiter the turbo is. Both engines have the same turbo and everything else. (Exh cam is a little diff on the 2.3)

Bigger bore will help unshroud the valves and we have discussed that in the past. You can get about .1L more going as big as possible 93mm.

Anyway back on topic 28RS .64, t5 cams, black injectors and some software = nice daily driver that will last.

I'm looking to gain much more top end. I'm not sure how to do it though. I don't want to be limited to like 135mph top speed. When I hit 135 in 5th gear i'm only at like 4.5k revs? I don't know how to get the rest of my power. PLUS, eventually I want to be getting about 400hp, wouldn't that bee straining the little 2.0l engine?

Then get a huge turbo for top end... like Nick said as long as you have the proper hardware and software you won't be straining your engine, you will just be working within the limits of your upgraded mods.

As for the speed governor I drive a basically stock '00 9-3 with full exhaust, intake, and MP IC. I've been higher than 135... with power to spare.

Could I be missing something when I drive? I just can't seem to get any higher than 135mph.....it just goes so slow once I get there, I don't see where I would even Have room on a road to give my car time to accelerate past that point.

Any recommendations on a turbo set-up?

Uh...

How and why are you driving at 135?

...and why would you need to go past that?
