Question looking for general info on the Vig

Had my car in the shop today at school to do some "tests" on for some worksheets. I was the only on in the group with ABS. But either way one of the guys in my class comes over as it's on the lift and starts asking me questions about it.

1.) What turbo does it have in it?
2.) Power and torque ratings? (I know it's 225 hp and 252 lb/ft) My question about that is: is that bhp or wheel power/torque?
3.) How much bigger is the stock intercooler for the viggen vs. a 9-3 HOT?
4.) How much larger are the brakes on the Viggen vs. 9-3?

He has a heavily modified Subaru Impreza with a "JDM" motor in it. I know this is synonymous with "ricer" but this is one nice set up. It was built to run 100 octane from Japan...yikes . Great sounding exhaust (no cats..), lowered, 18's, racing seat (like hard core rally). He used to rally it when he lived out in California but now he's just going to autocross it here.

If you guys have any answers to my questions above, that would be very helpful and greatly appreciated.

1) td04hl-15t 5cm exhaust housing
2)all bhp or "in the motor"
3)dont know if the ic is bigger just that instead of a dual pass its a single pass and better flowing
4)not sure

careful of jdm subarus they are one car that really benefits from jdm motors

All Viggens had the dual-pass, which is the same as the non 9-3 SE.

Yes, Viggen rotors are 308mm. Regular 9-3 are 288. Older ng900's had 284, I think before 96.

Yes, sure am.

Viggen is the same as 9-3 SE, which is cross-flow. All non-SE has the dual pass.

Like they said, your rotors are bigger but the caliper is the same size, it just uses a special bracket that moves it up and out a little bit.

Funny thing about the IC. I think after 2000 all 9-3's use the "viggen" IC. I was looking at a 2000 base model 9-3 yesterday and it had the crossflow cooler. It also had a 5 button SID which is pretty odd.

Anyway about the japanese 100 octane. It's probably not that crazy because its probably just 100 octane RON, where as here in the states we use an average of RON+MON. Which is why you see this: (RON+MON)/2 at the pumps.

RON=research octane number
MON=Motor octane number

so 100 octane could probably relate to the rare sunocco station that carries our 94 octane

WHOA! That's weird, why would they rate the car lower than what it puts out? 284 lb ft, dang that's alot of twist. Can any one else verify this? I would be wicked stoked if that's not far off. Not that I don't trust you Stx, it's just they rated 225 bhp and 252 lb ft, those numbers are alot larger, mainly thr toruwe rating (not a bad thing though ). Thanks for the info guys, this has been very informative for me the relative newb with Saabs.

The guy with the Subaru says he has to run 100 pump octane (RON+MON)/2. He puts the highest grade he can get from a pump then octane booster. I should have asked him what he uses but he says it's wicked expensive.

so this Viggen dynoed out at those numbers today? or did I just read wrong. I couldn't make it today, my best friend's graduation was today. If that dyno run was today, who's car was it?

well you know what people say about T7, it can adapt down and possibly even cause a loss in power.

Have you Dynoed it stock?

I wonder what it would have put down?

Also I know that you have had problems in the past...didnt the dealer replace the turbo?

oh ok, just making sure he really did need that high of an octane Glad to see you know the difference

yeah the turbo has 25k miles on it. ive put 27k on the car while ive had it since the end of january 2005. the first dyno day it was mostly stock, at f1dyno i forget the actual numbers, 193 whp and 240 wtq. its definitely stronger since then. so their dyno may have been reading wtq high, as they suggested at the time. i am happy with the accuracy of this dyno though. il llikely be back there to dyno the next time i need to. sorry ot be OT. the point is there are unexplained variations in viggens.

yeah, he told me it needed 100 and I think my eyes bugged out because he laughed. He also said it pinged with anything but a mix around 100. It's the "JDM" 2.0L Turbo. He's done alot of mods and it is a really nice car. But 100 octane is just a bit high.

they made us memorize all that ROM and MON stuff in my intro class because they thought it was important. Well, I have forgotten most of it but I do remember the difference between RON and MON and what the pumps put out. Finally came in handy.

This is very true. Mine developed a problem that the dealer so far hasnt found and I have been throwing parts at it. They drive it and say it feels like a normal Viggen yet I know its missing power. Most people who would drive it think its fine, but when you own the car and you felt it the day it lost the power you want that power back. I think 100% healthy stock Viggens show it on the dyno, anything less and you wind up with a car like yours or like mine. I still have a couple more things to try.
