Opinion on preassembled "power kits" (eg Vishnu, Cobb)
Just as the title says, I've done searching but havn't found much. Just looking at my options, so what does everyone think of them?

Blitz nur spec is about as loud as you can get. Its a cherry bomb muffler, straight through, apexi n1 style.
Everyone uses "prefab kits" in the sense that you're talking. Virtually everyone goes with the big name engine management systems and pieces things together from there. A shop will give you a better tune that OTS (off the shelf) Cobb maps, so basically its foolish to say or think that you're going to be getting a better "tune" with an off the shelf map, because its not nearly as efficient as a protune, i.e., a tuner specifically tuning your car for the mods it has. Utec, ecutek are getting to be huge names. They're a bit more aggressive tunes than cobb. Vishnu is expensive, but has very aggressive tunes and makes good numbers as a result - I don't think its nearly as popular as it once was, because I rarely hear about vishnu anymore, when I used to hear about Shiv doing custom tunes for his vishnu users on a regular basis. Cobb is reliable and good for the stock mitsu turbo (the td04) and for the subaru turbos - the twin scroll, v series of turbos. Some say they have good results with another mitsu/garrett turbo - the 16g and cobb, but I think if I went with something besides the vf series or the td04, I would get a different engine management system. These are all piggy-back systems and not stand alones. |

I know the Nur-Spec is but I heard that the (correct me I'm wrong), the Nur-Spec Touring is reasonably quiet.
As far as the tune goes, I know that tune will be "better" from a shop. The question comes if their is someone I can trust to get it tuned. And while it might not make AS much power, the more conservative standard Cobb/whatever maps are less likely to send my engine nuclear (correct?) So I'm basically hearing what I thought, piece it together myself. Which brings one question, what type of management would you suggest? |

I mentioned about engine management in the prior post. If I were sticking with a td04 or the v series turbos I'd probably go with whatever I can get my hands on cheapest and there's a good local tuner around for. I have the Cobb AccessPORT since I stuck with the td04. If I went to a 16g, I think I would have bought a vishnu, ecutec, or utec depending on the price and the tuners around. Engine management all comes down to personal preference. Cobb is usually regarded as the "safest" tune - which should be the most reliable but make less power. |

Cobb has ots maps for fp 16g vf 30 and vf 34.A pro tune would still be your best bet but atleast you can use those for the time being.Cobb maps are conservative because they are maps for everywhere.

Considering subaru uses bosal for aftermarket replacement parts, I would say that its definately on the mild side of exhaust notes by large. There's single tip, dual tip, etc., etc. The aftermarket bosal sold for the STi through the factory, isn't much louder than the stock STi axleback. Then again my buddy got pulled over in his '06 STi and the officer thought the exhaust was aftermarket because he deemed it too loud, until my friend informed him it was stock and he was shocked. |

i know one plus to buying a pre-assembled power kit is that it usually saves you a little bit of money. Cobb's AccessPort plus their full turboback is around $1500 i think where normally buying the tbe and AP separately would retail for $1750 or so. I feel it depends on what you're looking for out of your car. Raw power, finesse power, driveability, etc. Certain companies are known for certain parts. A lot has to do with the sound of the catback you're looking for too. I know many people have been impressed with Cobb Stage 2 and that is what I am attempting to get installed and running so I can let you know from there.

Cobb is good bang for the buck...

I won't claim Cobb is the best, but with my stock turbo, Cobb AP, & TBE, the car is faster than my old BMW ///M635csi by at least 1 second in the 1/4 mile. Most street cars can't touch it now, and it is pretty user friendly on STAGE II. I am adding a new turbo soon, PE 650cc injectors, and a big top mount IC. I plan to keep the Accessport, get a "Pro Tuner" to do a few base maps for my Access Port, and I will copy them in "Street Tuner," and mod them for different weather conditions, etc. Accessport isn't "really" piggyback. It is a re-flash unit which still piggybacks SOME of the features of the factory ECU. I prefer it to other devices, simply because it will allow datalogging, etc, with the proper setup, and Street Tuner is crazy cheap (200) now. THE BEST ECU is a stand-alone unit. Unfortunately, these require a LOT of reverting to stock to pass inspection. I paid retail for the COBB parts, but I got them all in one lovely shipment. IMO, the COBB downpipe is ESSENTIAL. You can run whatever catback you wish that will mate to the COBB. Quality is top-notch on the COBB downpipe. The catback is nice, too, but if you are budgeting, you can use ANY catback, even stock for a while, or grab a $150 eBay catback if you are daring. I feel that the power gains with COBB stage II are very reasonable. They are not so overboard that you will kill the car in one launch, and they are CERTAINLY nore daily driveable than stock. STGII FTW!! ! ! ! Saab-on-the-Cobb |
