Ive been lurking about for some time and was wondering if anybody had some input on these two packages.

1. Which will provide bigger gains?
2. Which would be more reliable or streetable?
3. Will either be smoggable?

or

-Stainless Sport Exhaust

thanks

 

This is an interesting question.

 

I'd comment but I'm biased

 

If your in the States go with a tuner that actually can pick up the phone and or even custom tune...

Sent you a PM.

I would not look towards K24's, the response is not as good as modded K16's, with the right setup.

 

Id put my money on the EVO X50 car w/ K24s from 50 - 130+mph

 

You seem like you are shopping specs and packages... as Markski said, you should shop for a TUNER. Find the 'brains' behind a 'mod plan' and then 'package' will be defined by your needs and budget.

If you are in SF, Sharkwerks is local... Kevin at UMW is up in the northwest (no sales tax). There are others...so your homework.

PS There are NO CARB CERTIFIED ENGINE MODS for California. Many will 'pass' but only because the shops don't know any better. Don't change any engine hoses, don't change the air intakes. I choose a Europipe exhaust as it looks pretty stock...

 

All I would suggest is a good tune, a good exhaust, some DV's (and good plugs) and you're set

 

Does you car have K16s or K24s?

 

Actually im in the market for my first 996TT the 2 vehicles of interest happen to have these different packages.

 

Ca anyone with these actually installed weigh-in, I'm interested in seeing more about this as well.

 

I've had the "full monty" Evoms stage 4 on my car since April, 2006; about 24k miles ago ('car now has 44k miles). 'Owned car since new; 'came with X50 pkg.

Install done by an Evoms dealer, along with total suspension mods. Those who say "find a tuner/installer" are correct. Many horror stories when installer of these various pkgs/components doesn't have extensive expertise.

My car has been "bullet proof" since mods completed, including many track days; being driven on track @ 10/10ths by professional drivers, etc.

I consider this a tribute to the Evoms pkg; but also the skill of installing shop (who also built my Dinan S/C'd S3 E39 M5; which has also been "bullet proof" for 3+ years and 34k miles).

IMO, regardless of pkg "name", who did installation is critical to consistent performance. Find out who did installation on each car you're looking at, then call pkg mfr to get their opinion of that shop.

BTW, I live in Calif. and have had no problems with smog compliance; w/o changing anything before testing. IMO, 'vast majority of smog stations have no idea what they're looking at; 'car easily passes "sniff" tests.

Good luck........
