Thats one thing I believe. So I guess I better start searching. Again good thread

uhh... there is two 'ssr's , one that makes rims : speed star racing, the other i think sr motorsports makes performance parts, I don't theyre the same. Hoffa do a search you should find plenty of threads with people with sr parts (i.e flywheels,cat,pullies,etc)

I have the SR motorsports air intake (really pricey, but looks and performs well), and their lightweight flywheel (pretty low price). I am debating on getting their underdrive pulleys. I haven't had any problems with those guys, they are top notch and knowledgable. If you're looking for their website it's www.srmotorsports.com enjoy guys/gals.

Someone here had a SR Motorsports intake and it was easily the best sounding 8 I've heard with an aftermarket intake. I can't find the sound clip though, anyone have it?
Also, did CZ start shipping the cat/midpipe with a different resonator?

I may have it on my computer still.. give me a few minutes to look.. if not I would be more than happy to bring out the digital camera, make a video/sound clip and email it to you.

Found it, if you want it still, just PM me. The file is 8mb, I'll try to zip it and make it smaller..
**** EDIT **** I stripped the video from it, so now it's just sound.. much smaller file size
Only 500k, so I'd be happy to email the sound clip to whoever wants it

when ordering the flywheel..what else do u need to order or do u think they're "package" is worth it the one that includes they're flywheel, and ACT clutch and parts for install?
and is the high-flow catalytic converter any good? or does it make it sound like a honda civic? and lastly does it go w/ the racing beat cat-back exhaust?
sorry for so many questions guys

You only really need the flywheel. The clutch kit is mainly if you're going to take it to a track, but for normal street driving, your stock clutch will be just fine. If you call SR motorsports, just ask to talk to Greg. He'll get you set up with what you need for the flywheel. Pretty much you'll be buying a counterweight, flywheel, and hardware kit (nuts, bolts, those things).

Well, in my case I only have 1700 miles on my car... so everything is pretty much new still.... any transmission experts out there that care to comment?

He ordered the parts a couple of weeks ago. So he'll be working on my car probably next month. I gotta get some other crap in order before I go turbo though. Some company took off my doors (long story) , and then I got a grindy reverse. (and nope , it an't because I am shifting into reverse wrong) , and some other crap , including college starting....
Oh ya ... went with him to home depot the other day cause he was buying stuff to make hoses or something ... :o

Like I said, there isn't a viable turbo kit on the market. The SSR has the turbo in a very bad position. The heat from it is really going to mess some components up, and you have seemingly random pipes running all over the place, causing restrictive bends. SSR just had a hardon for getting a kit out. From trusted members, this kit is questionable...
There are '8s with custom turbo set ups, but I don't consider custom setups to be viable. There is alot of R&D that has to be paid for (esp failed attempts). Most people who build turbo kits like to get paid, and that makes the cost rise even more. Not to mention the amount of metal work that needs to be done.
I, personally, wouldn't trust a geek friend to turbo my Renesis unless I had enough to buy another crate motor. If he blows up your engine, it's going to cost alot to fix it, and it won't be covered under warranty. Unless this guy has turboed alot of cars, I don't know if I would jump on the band wagon so quickly. But you jumped on those prototype lambo doors pretty quickly...
As far as the other problems you have to fix, I read your other post. I'm aware.

Well, an aftermarket clutch is high on my list - the takeup on the stock one is pretty vague. It's hard to make snappy changes between the top ratios. I'd do it for that reason alone.
That SSR kit sounds GOOD - but it's bloody expensive, don't you think?

I'm not overly familiar with modding, but just out of curiosity, what effect would any of these mods have on fuel efficiency, and which of these modifications/upgrades would be viable on the A/T 8?

I've been folowing performance mods for the '8 for some time now... many of which I have had on my car. Here's what I think is worth pursueing:
Lightweight Flywheel <== Totally worth it. May not add that much quantifiable HP (although it feels like around 20 HP or so) but makes a huge difference in the performance of the car nonetheless.
Pulleys <==Worth it if not spending $500+ dollars on them. ~10 HP gain.
CAI <== Some are ok (RE and SR) but probably not the most cost-effective mod. Adds 5-10 WHP, but may cause idling problems too depending on your individual car.
Removing the front screen from the MAF <== This was an experiment done in the early days of the car. It didn't give any performance gain, but what it DID do was destabilise the airflow over the MAF and cause idling problems.
Header <== Not worth the $1000 + that those currently on the market cost. Watch for Borla to come out with one, it's apt to be as good as one can get without porting because they are taking their time researching what works and what doesn't.
Highflow Cat <== Definite improvement if you can handle the noise. They are a lot louder with an aftermarket catback exhaust. Adds ~ 10-15 WHP.
Catback <== Worthwhile mod IMHO, even if they only add ~5 HP. The improvement in sound alone is enough to convince you that you've added more HP than you actually did.
Weight reduction <== Probably worth it, but pretty hard to accomplish.
Other mods to consider:
CanZoomer Piggyback. No, it doesn't work perfectly for everyone, but it does for most. And you can tune it if not perfect out of the box and make it run really well with your car. Adds up to 25 WHP, usually a bit less though.
Nitrous: Adds 55-75 HP. Still in development, but looks promising.
Forced Induction: Supercharger or Turborcharger. Still in development, but I expect to see a couple of kits within a month or so (Sunflower-ATI/Procharger and SFR) and probably 3 more on the market by December. Adds 80-120 WHP, maybe more if the Renesis proves to be strong enough to handle it.
Porting: Still in development. May add 50-75 WHP.

I plan on going custom with my car. One of these days, I'll have CFD, and FEA programs for building my turbo setup. I have AutoCAD2000+ on a disk, which I plan to use once I get a crash course from my high school drafting teacher.
Or I could use the trial-and-error method. Either way, whether it's custom or a kit, you still have an equal chance of blowing the engine. The key is in the tuning.
