Default Making the jump from no mods to JSP stg 3 today

Well, after driving my 2002 93 for a year I'm taking the plunge. I spoke to Jak on Friday and he was knowledgable and very eager to help. After talking I have decided to buy a full stainless exhaust setup and have the ECU tuned to boot.

Jak was saying I can expect somewhere in the area of 280hp (at the crank). I'm hoping this makes a significant seat of the pants difference in the car. I'm sick of seeing the WRX's in town here, now I should be able to give them a run. Merry Christmas...to me!

Thanks guys, short of what I've bought now today I'm a little lost on what to do next. Logically I would assume that a larger turbo would be in order, I'm going to talk to Jak Monday about a t-28, or if he has other suggestions.

I can see where this is going though, all of the cars I've owned in the past 5 years have been intended to be simple daily drivers. Now that I've started modifying my 93, I can see myself really pushing the limits of the car.

Have you bought it already? Why not wait a bit and then you could go stage 4 with the new turbo?...

sure hope you're getting a new IC (Forge, Jaks or KJ) with that bump in HP...be foolish not to...run high risk of melting down the motor

spot on!

Why are you upping Stage3 BIGSKY before prepping the car in readiness for the upgrade. Surely there are handling/engine tunings/upgrades that need to be thought about. Its all a balance is it not?

Dont want to be a bummer on it, but I wouldnt want to see a fellow saab dude fry his motor.

I agree!

If JSP Stage3 is even in the very rough (higher or lower) vicinity of stock Viggen power/torque, given the softer stock NG900 suspension, I dare not think what driving it must be like. Fun maybe. But still a bit scary.

Definitely agree with what Mike has stated. BUT since you've got the power pieces on order, I'd suggest at least buying a steering rack brace kit to help control the torque steer and the 22mm rear anti-roll bar to help you in cornering. All these parts plus the Stg3 will REALLY change your car. GenuineSaab has the pieces for not too much money.

Also, you may want to consider some preventive maintenance type items such as the headbolt replacement, MAF replacement, spark plugs changed to NGK BCPR7ES-11, use of a good quality synth oil.

Maybe even consider booking time on a dyno after installing the Stg3 stuff, just to see what power/torque you're making at the wheels and getting metrics like Air/Fuel ratio and Boost Pressure

Have fun and please post pictures of the exhaust and review of the JSP Stg3.

The thing is once you buy a staged tune from Jak, he usualy will work with you to dial it in on the dyno and give you another flash or two to get the car working just right. If you do decide to up the turbo and go with a stage 4 or 5, I would bet Jak will make you a pretty good deal on the sw to accomodate your new hw I had Jak's Big T28 and it was screaming! I ended up making 265whp and 310wtrq uncorrected in Denver a mile high with a large ic, Cold air intake and 2.5" delivery pipe. For this power level, the steering rack brace and rear 22mm anti roll bar are very helpful. I did this before the suspension and brakes and it was still fun to drive. Good Luck with your project and I think you will be happy with the good flowing exhaust Jak makes and the new sw to run the new hw. I agree a new larger ic is in order to keep your intake temps as low as possible, John

The suspension on my car definitely needs to be addressed. To be honest, I was really let down with the handling on my car, so it's definitely in the cards to do some work there. I'm not one for aesthetics as much, in fact I'm more in favor of building a badass sleeper that outruns and outhandles most anything locally.

Has anyone had any experience in running Jak's tune in extremely cold weather? Wisconsin gets pretty bitter in the winter, and the last thing I need is problems with the way it runs in -20 weather this January.

Thanks,

Mike

Hey SAAB Family have you had your car on the dyno? I curious what kind of gains a t-28 will yield vs. the cost of adding it. This is a slippery slope, I have 2 weeks before Jak gets the stage 3 exhaust parts to me where I'll be agonizing over a larger turbo!

Like stated above in a few posts, book time on a dyno or better yet get yourself a wideband now! Bring DP down to muffler shop and have them weld a bung on weather you have a wideband or not-it can be a hassle having it welded on after the dp is installed.

Tip: If the DP is off, make sure to hold it up to a strong light to check for pinhole leaks at the welds. Some other folks have found pinholes or seam leaks. It's not necessary to pressure test it nor to use a smoke machine. A strong shop light will do the trick...


You're going to have fun!
