Yeah I did... had the battery disconnected the whole time i did the install!!! Im begining to wonder if i got the Top Speed Headers and M2 exhaust system, If that will compensate for the (LUXURY CAR) lag. I mean Im not trying to drag my GS just give a bit of confidence as it sits next to my friends M3..lol. Well if you have any insight on the stated above mods let me know. Thanx

 

Just give up Kraven9...nobody talks more than Sak... 12k posts in a short amount of time...

 

The exhaust/header will more than likely reduce low end torque even more. You would be increasing airflow through the motor without any type of fuel compensation. Add a fuel computer into the mix and you will realize a good improvement, especially with the header/exhaust (keep in mind that you will have to use an O2 simulator for the secondary O2 sensors (post cat) if you run the header. If you are just looking for more low end grunt then a higher stall torque converter is the way to go.

On a side note, I ran a switch pitch TC (3400/2200) in my GN with a turbo 400 trans. I am looking at the hydraulic circuit on the GS trans to try and figure out a way to route pressure through the input shaft and to the TC. Modifying the TC to switch pitch is easy (lots of work but easy). Long term project by all means.

Anyone have any experience with aftermarket, higher stall torque converters for the 2nd gen GS3's?

Thanks,
Dean

 

true true, i talk ALOT, but atleast like i said 90% of them are incitement and informative and on topic not just frivolous posts.

always Thomas breaking my *****

back on topic

 

STOP DERAILING OTHER PEOPLES THREADS!!!!

And OP, Stick with the SRT if you can find it. I was always thinking of making a BFI for the GS, but I'm under the impression it wouldn't be as easy as the SC was back in the day. Drop the Dragon and go back to stock and throw in a K&N and call it a day. If you wanna spice things up, maybe cut out the air baffle in the intake tube and seal that up? I know that is built in there to quiet the intake up. Either way good luck.

 

hahaha i love sarcasm

 

Why not make your own custom intake?

 

Just get rid of the Weapon.. Go with the SRT!

 

STOP DERAILING OTHER PEOPLES THREADS B!!!!



Yeah I have no luck with air intakes, I had wasted money twice on two other cars prior thinking I'm gonna get a few ponies.....NOT. Forced induction or just leave the motor stock.

 

yea installed one my gs and feel fine till i hit 3800-4500 and the car feels like its choking then runs fine in the higher rpms.. going to change plugs and clean the maf to see if that helps..

actually the SRT with harness will net you in the area of 22 hp i believe

this will help alot, just get the SRT intake $500 but will get you around 20 hp

 

So in essence the Weapon R is worthless and the SRT is the way to go? what is the real difference between the 2 systems? Also what fuel computer added would be the way to go Dean???

 

lol...sounds like you mad. I was in the 2nd gen IS forum and I saw you post similar things. I'm not going to go search for it and bring it up, because I don't care what you post. If that's how I feel and want to say it, then I could. You bring up invalid points.

To the OP, this says for 98-00 but they have for the 01-05 model also. You could probably find a used one in the classifieds if available.

Most of the aftermarket intake systems are the same: a pipe with a filter on the end. There is differentiation with pipe size (some are 2 1/2" and some are 3" in diameter). Some also have "heat shields" which can easily be fabricated out of sheet metal. The fuel computer is what separates the SRT system. You can go that route and get good "plug and play so to speak results (you do have to hack into your ECU harness but you need to do that with most if not all piggyback fuel computers). An S-AFC (also referred to as NEO--the NEO is the latest version, basically a replacement for the S-AFC or Super-AFC) from APEX would work. Again, the main problem with a larger diameter intake is that the motor will run lean. With the stock, somewhat restrictive system, the AFM gives a 100% reading at WOT at about 3K RPM (at least on my car). So increase the pipe diameter and the AFM may not ever reach 100%, probably about 15-25% less than the actual air flow. So the motor will be lean. The ECU can compensate for about 10% (using O2 sensor feedback) but when the ECU has maxed out fuel trim it will not add any more fuel, the car will be sluggish and you will more than likely get a check engine light. The piggyback fuel computer interrupts the AFM signal and increases or decreases it (depending on the settings on the unit) so you "fool" the ECU into thinking there is less or more air volume and the ECU en-richens or leans the mixture accordingly.

A bit verbose but I hope that answers your question.

 

Well said DeanGS!
