a little extra horsepower

So here is my idea I have a 03 auto. I already have a tuner headers and a kn filter. My ideas are 4.10 and an upgraded diff. Next idea was a bbk throttle body and a cold air intake but I have heard that the throttle body wasnt worth it and if the kn filter works just as well as a cold air? What do u guys think and do u have any other suggestions

Re: a little extra horsepower

well, it depends on the Cold Air intake, if the intake requires a tune, it usually has wider piping than the stock airbox, so you will gain more whp.
the others are kinda iffy.
the throttle body won't make much of a difference, but is good for 10-15 whp, if tuned. I'm not sure your car comes with a dif, but if i were you i would look into upgrading into an 8.8 rear end.
and if you're gonna get it dyno tuned, i would recommend meth injeciton, easy 50+ whp.

you should already be able to run with any 90's model v6 camaros...and even the first run of newer v6 camaros before chevy started working them up a bit

Re: a little extra horsepower

thats only a 20-30 hp difference and they weigh a fair amount more then you...plus their gearing sucks.

Meth injection?

That's for S/C or T/C

And a aftermarket throttle body will be good for 2-4 HP maybe 6-8 tuned

Oh and I'm sure there are methanol N/A cars running around but I'm sure they are running high (really high, since it takes high compression) compression, and since it takes a lot to make high compression in a V-6, I'm pretty sure our bolt on modded OP doesn't come into this category. Stick to wrestling since modding isn't your thing yet

Meth can be run on a n/a engine but corrosion is a bad issue. Gears should be your main priority

Yeah right now gears and a LSD are my main ... But I'm just looking into what elese after that. If I do add the throttle body will the stock intake allow me to see HP gains with a tuner or will that need to be larger as well?

Stock intake will need to be larger but a throttle body won't do much unless the rest of the intake system is ported for it.( manifolds, and heads) and also as you upgrade intake...when you car inhales better it also needs to exhale better....so look into a good dual exhaust system as well.

How do you port it? Who do I have to take it to to get them to port my intake? How much power increase?

If the intake only is ported then I would say no a tune is not required but if you port the heads and intake and put a throttle body on it I would suggest a tune to boost your gains. After all the porting w/o tune you could get about 10 hp but if you get a good tune for all that you could be looking at about 15-20 rwhp. But that's if everything is done PROPERLY.

They usually charge anywhere from 200 to 450 I've heard of. And the downside of doing it yourself is taking to much off or messing up the taper and actually hurting your performance

Random thought, what is the biggest reason why the 3.8 only has 190 HP? I realize it wasn't built for performance and was a van engine. I get that. But what is holding it back?

Another random question lol instead of porting the intake and doing work to the motor would it be more benificial to swap a 4.2 in? I heard doing a 4.6 isnt worth it but what kinda gains can be seen with a 4.2 and how hard would the swap be?
