Hey Guys!!
I think (pretty sure) I am going to try and sell my Stillen Stg2 SC kit that I never installed and keep the coupe NA.
So, since I haven't been on here in a while asking about NA "bolt on", I thought I would re-ask the question to get some good feedback and maybe start a chat or two about what's new out for our coupes (03'-07' models) for the Naturally Aspirated enthusiasts.
What I have: 2003.5 Coupe
Gordie Grouding Kit (love it!)
STILLEN "True Dual" cat-back exhaust (I kiss it good night, best mod I've ever done for this coupe!!!! - HIGHLY recommend)
What I was thinking of getting if going the NA route afterall:
1.) Motordyne 5/16" spacer w/ iso thermal
2.) Motordyne MREV2 lower plenum collector - can I use this on my non-rev with the 5/16" spacer with POSITIVE or NEGATIVE results!?!?
3.) STILLEN headers
4.) STILLEN High Flow cats
My main worries are the Motordyne combo asked in question #2 and then if that passes for a "good mod to do", then what would HF Cats and Headers do with that combo - good or bad outcome!?
I do NOT want to LOOSE TQ, I want MORE!! he-he
What else could I be missing for NA route? - Oh the ECU reflash! Forged Performance is a bicycle distance from where I work. Let them do the ECU or send it off to TECHNOSQUARE?
All comments welcome - I remember to put on my flame suit for anyone having a bad day.
Thanks Guys!

- The MD spacer with ISO is a no-brainer for NA
- The MREV2 would yield positive results, but no where near as it would on a revup
- Ditch the idea on the Stillen headers. If you are going to do headers, get some quality long tube headers. I can't see any justifications for parts & labor on 95% of header installs
- Ditch the idea on the Stillen HFC. Though I am a fan of many Stillen products, there are MANY better alternatives out there. I would only advise 3 HFC: Fast Intentions, Berks, or Crawfords. If you are really serious about NA, go with resonated test pipes.
Going with a spacer along with HFC and headers should not make you lose any torque. In the other hand, you will gain a good amount of it, especially after a tune.
As far as a reflash, go with Osiris hands down. Even though Technosquare is a great reflash, I don't see any reason to get it over the Osiris.
If you like to see my NA project thus far, you can check out my thread I posted a few months ago via my profile. I have not done anything "crazy" like some other people have (i.e. NA engine builds, cams, etc). But I feel that I did chose my modifications wisely and my results were great. (Considering how long it took me to get as far as I am now, I better have done the amount of research I did
).Research, research, and more research is key!

My 0.02¢
I'm no "guru" by any means but I'm going the n/a route on my dd G. . .
Installed:
- Z-tube & Pop charger combo
- MD 5/16" spacer and MREV2
- MD Y-pipe & Dual Harakiri cat-back (sooooooooo sexy)
- Sun Auto Hypervoltage system
Have yet to install:
- Crawford equal length headers
- Turbo XS Utec
Have yet to purchase:
- JWT S1 cams
- Crawford HFC's
Not looking to bust records or anything but I'd like to keep this as my very reliable daily driver and improve on the VQ. . .
Stillen - I wouldn't get their headers. . .they are the same as every other header out there except for Crawford's and Megan's longtubes. . .at least these 2 companies are proven to make power with their designs. . .
Motordyne - A no brainer. . . Tony has done his homework on all of his products and stands behind them. . .(highly recommend his exhaust systems!)
Cosworth Plenum - A quality product; I had one on my car but sold it and went back to the Motordyne MREV2 and spacer. . .doesn't seem worth cost the unless you're going full-bore N/A or just plain F/I
Tune - Tons of options out there, guess it comes down to how much you're willing to spend. . .XS Utec - - - - - - -> Haltech Platinum
Very convenient that Forged is a hop skip & a jump away from you, they'll be able to help you out a lot as well!
p.s. - as Skaterbasist said, Research IS key

Other than that, the options are to build the motor, boost, or boost a built motor. While boost may be easy power, it's just not what some of us are looking for (I can't speak for the OP on that)
Of course you can always cheat and get a higher final drive instead! (or preferably, everything)
I'm thinking that after intake, plenum and spacer, full exhaust, and tune, there won't be much parts that'll offer any kind of decent gain. An additional 15-20hp and 15lbs of torque is a very welcome gain, even though it's an additional couple thousand.

Because it increases acceleration without making more power... IMO, it's a great mod, but it's cheating lol
Sorta odd word for it. It's not "free". You give up top end and some possible MPG.
It's not cheating!!!
IMO nitrous (aka cheater gas) is totally cheating (but since its an actual power adder it must by okay in your world).
Also – your logic means an OEM MT is cheating if it races an OEM AT because it has sorter gears
.Your logic is totally flawed.

My car came with cams 
I don't think many have done the cam upgrades just by themselves. Off the top of my head, I can only think of Mike (im sure there are a few more on the site). Others have done a full NA engine build.

_Jb, I like your "mix":
Cosworth Plenum | Crawford Headers, HFC | HKS Ti | Carbonetics LSD | 4.083 FD
Osiris Pro Tune | JE 11.7:1, Eagle Rods, JWT C8R Cams, ARP L19 | ACT Fly | JWT Clutch
Where are you coming out WHP/WTQ for all these NA mod's - VERY interested!
Thanks Guys!

Hmm... I thought they had the ability to flash all the ECU's now, but you might be right. Something to ask about for sure. Sharif should know... Or maybe Rich will pop in and answer that question.
