I have been thinking about doing 1 of 2 things with my GS

1. 2800 TC
2. Last of the Millen SC kits

Now I know the TC has the ability to shave times by .5 sec and makes the car more responsive.
What kind of performance gains should I expect from the SC kit with no other changes?
Is it worth the cost of the SC over the TC?

I am guessing I can get the TC installed for what.... $1200

The SC is what... $4500.00, Blood, Sweat, and maybe some tears...

RULES

1. Don't tell me to do both.
2. I don't want the LSD.

Either bolting on the SC or installing the TC.

I drive the car maybe 2 times a week... short distances.

My guess is that the SC will make more power once up to speed while the TC would make 0-60 more entertaining.

Does anyone know if the SC is even still available?

It's late, I am rambling...

My friends say just to spray...

well, um, lets see

1. TC= cool

2. SC= way tooo cool

I vote for SC

if you want juice of course the sc will be a better choice, the car will be a lot faster than the NA with tc of course.

but imho the car with tc is easier to maintain than the car with sc

The TC makes you THINK the car has more power..

The SC gives the car more POWER....

since it's not my money, you see what I vote for.

I wish someone knew what the difference in performance is with the SC. If bolting on the SC alone in bolt on trim was only going to be good for 13.5 quarter mile times I wouldn't be as interested in spending close to 5K for it.

It adds 100HP to the rear wheels correct? Anyone have a guess of what this would put the 1/4 mile times at?

Why not send a pm to some of the guys in the FI Registry and get their take on FI

I'd say go with TC since it's almost impossible to get a SC set any where. Even you can find one, you'll spend lot of $$ to tune it to give you 100 HP at rear wheels.

CinFulxgs

I was under the impression there is one left at Rod Millen and that they don't need tuning to accomplish 90HP to the wheels. They are intended to be bolt on and go... or at least that was my take from other threads... and that tuning was only needed when adding more power than the intention of the the kit.

not a good statement imho the car is a lot faster with the tc, not just think

well i also read that the last kit was gone..... probably you should call to verify. and yeah, if you put that "stock" kit on, i dont' think you need ecu tuning

GQD_GS4

do the TC...its the best bang for your buck. and if you like the results, then add the SC for double dosage...

chuckb

I said TQ makes you think car has more POWER, I never said it doesn't make it faster- convertor just get's you into powerband quicker, like slipping the clutch on a manual trans.

SC adding 100 hp is a whole differnt story, I guarantee the SC car will kill TC car on highway.

like I said, if money is not an object, it's an obvious win for the SC.

CinFulxgs

I totally agree that the SC would beat the TC highway but I will be really extending myself to get the SC and will not have money left over for the TC. I would think that the TC performance increase is pretty good for the $$ as compared to the SC especially of the line where I am probably more interested in the power. The car seems fast enough already from a 60mph roll on the interstate.

Now if the SC without other mods could get the GS in the 12.5 1/4 range I would be VERY interested... but I wonder if SRT intake and TC or SC would both get the car into the low 13's...

Intake and TC would just make more sense.

chuckb

to get a car as heavy as ours with an auto trans tor run 12.50s would take huge amounts of horsepower. Like 500hp.

I don't think an intake and TC will put you low 13s either-more like 13.90ish.

GQD_GS4

chuckb is right on this one...our gs4's are theoretically able to do the 1/4 mile in 14.3. my FIRST time at the track, i ran between 14.6-14.9's with 18" rims, 225/40/18 (skinny) tires, and a drop-in k&n filter. even with my best reaction time of .101, i could not break 14.6.

thus, with an intake, exhaust and TC, you should definitely break the 14's, but you probably will not get past, say 13.7's in reality....still, 13.7 in a car our size is uncanny!
