77mm vs 84mm pulley, is it worth it?
I paid around $600 for my Kleemans on eBay and then about $600 for install at a fab shop and was without the car for a day. This is just my $0.02.

There are plenty of header dyno threads here. They all pick up power across the band and not just at peak rpms.

regardless you will need a tune with the pulley so that puts you at $1k roughly anyways. I think you will get more bang for the buck with headers IMO. Bang meaning power, sound, cooling and feel as an entire package. I think the 84mm is kind of a waste of money but that's personal opinion. I feel you'll outgrow it really fast where as the header package make the car fun to drive for more reasons than just the new found power.

I haven't done much in searching for headers because I'm not ready for headers, that's not what this is about.

Headers
ECU Tune
That's it. You don't need a BWK, you don't need to split the cooling, going to a larger TB or smaller SC pulley will only introduce driveability issues without giving *that* much seat-of-the-pants improvement.
The only other thing would be to get a set of drag radials once you finally *do* decide to go drag racing. Those will improve your ET's more than anything else.

I run an 84mm with stock cooling. I added shortys and I'm very happy with the way it runs. But when I started I was never considering hitting 10's. I set it up to run mid 11's if I change my pulley and add cooling and then tb. I wanted to keep the stock sound with cats. It's a family car not a muscle car to me.

I've gone ahead and bought a used 84mm from a member here, making it an even better deal. I'm excited to see the gain and how it drives, I'm less excited about the continued lack of traction with cold tires.

I have many fturns who have mid's and say regret long tubes because the cooling effects are far better and gains are more plus the car feels like a different animal .
It's winter but come spring do spilt ,and h.e for sure but till then you be ok .The t.b doesnt gain 35 whp so you can toss it out the window for them fake numbers ,fault codes amd major hiccups .
Yes ,it will make your whole setup breath more efficent when having the complete bolt ons but not fully needed unless you are chasing every last drop of gains .These cars stock are not to fast but after modded there monsters .Enjoy what ever you decide

The biggest problem I have with doing long tube headers is NONE of them are reasonably priced. I have a real hard time justifying over double the cost of mid tubes, when it is just a daily driver at the end of the day. I already have split cooling, heat exchanger I'll do before March when it starts warming up.

Shardul got a set on here of long tubes for 1000 bucks That's cheap compared to arh and mbh .as far as long tubes arh makes the best setup fron there collector to runners .
A 77 pulley can get you into the 10's even not tracking it's a nice feeling that you got a 10 sec poteinal setup and possibly will go with the rest of the mods .I'll tell yout the hit from the 77 is volient

I would look into these long tubes I mentioned cause you'll regret in the end .Long tubes arw good for 25 hp more then mods so don't belive thr hype thst mods are near the gains cause theRe not .
Look at the fastest setups and show me them using mid's ??.also note installing headers is not a fan task and if yoir not doing it yourself be ready to pay a nice chunk so this what I mean by choosing the correct set .At times cheap is expensive my friend

I ran long tubes, race cats and left my stock mufflers on. Car was quiet at cruise and a beast at wot! LT `s dropped IATs a lot, like 20 deg. as I recall and big power gains.

The project begins
Any suggestions on what manufacturer is solid
