orijinal_poser: Thanks... now, find me an ***-kicker for this kick-*** Turbo!
James: The audio system was an option in just '01's Turbo. It's Porsche's "Digital Sound Package", with two mids in each door, extra amp in trunk... can't remember what all the package entailed. I've PM'd me with my contact info. Thanks!
Kris: Thanks!
You guys have got to hurry up and find me a buyer... just last night, I was looking online for mods again for the Turbo... it never ends...
Just to keep the pix ***** show going, I had a couple requests for pix of the HKS SSBOV... so, here it is along with a pix of the clear center brake light:
HKS SSBOV replaces problematic oem Bosche units - vents back to intake
Smoked 3rd Brake Light

Thnx Mafia.
Had a request for pix of tire condition... here they are:
Front Outside - great condition
Front Inside - great condition
Rear Inside - Note where the wear bars are - plenty of wear left before wear bars are reached
Rear Outside - Again, note where the wear bars are... great condition

Sorry... no vids of the SSBOV in action.
Originally, I had it venting to atm.. performance-wise, no problems... the ECU didn't care either, so no warning lights.
The reason I vented it back to intake was because for whatever reason, the bov vents a very high-pitched whistle for our application... perhaps the airflow was directed perfectly at the fin or fins... not sure, but it was high-pitched and not to my taste. The purple fin was more of a "whoosh" sound, but in the end, I preferred venting back to intake... felt it looked more complete.

i had that same blowoff valve on my supra.. hated that high pitch sound that came from it.. annoying as hell hearing that thing whistle sounded sooo gay... my old trust/greddy gave a woosh sound that sounded better..

Yea i wasnt sure how that would sound, i hear the HKS's on evo's and sti's all of the time, so annoying. I like my bypass valve on my SC kit, blows off air instead of whisteling, would be cool on a 996tt but i guess not necessary haha..

All you'd need to do to get rid of the whistling would be to remove the tri-fin. My Bomex T04R Supra was running the Racing HKS BOV... sounded like one pissed off motor when grabbing gears... imo, sounded awesome.

4 allen bolts hold the outer heat shield... unbolt them (every other hole), pull the shield forward (bullet shaped thing), and the fin easily comes out. The purple replacement round-fin gets rid of the whistle, and is almost silent. Still, I ended up using a recirculating insert in place of the fin so as to vent back to intake.
I've been around turbocharging a long time, and in my humble opinion, the hks bovs are one of the best engineered valves. The higher the boost level, the better it seals due to the pull-type valve. I like the ssbov b/c it's a duel stage valve, for light and full throttle lifts (vacuum condition). Any more power, and I'd go with the Racing BOV.
As for naming... I guess you can say diverter valves is the popular name for valves that recirculate back to intake for european applications, which mainly use MAF readings even in aftermarket.
Aftermarket turbocharging systems for Japanese cars primarily use MAP setups, hence, it doesn't care if you vent to atm. That's why you see BOV's venting to atm mostly for Japanese applications and not European. My experience has been that the 996T doesn't care if it vents to atm... but, oddly enough, similar setups in Audi S4's don't work well at all.
A BOV can vent to atm or recirculate. If you vent it back to intake then you've essentially have what's called a diverter valve.
Hope that's enough study material for the night!

Also what is the purple replacement, just wondering, and do you find this setup to be the best overall, like basically what is the exact setup youw ould do fi you could do it all over again. Sorry for jacking your own thread, im truely sorry you could PM me or email me if you would like..
My bypass valve on my SC kit is venting tot he atmosphere, i dont have much experience with turbo cars, but know alot for the jap/european but not really 996tt, thankyou very much again

Your best bet is to buy my car already... 
The ssbov comes with a silver tri-fin insert. The purple insert has a large round fin as opposed to a tri-fin, allowing the concentration of the blowoff to exit without whistling. As for capacity, I have a friend that works for HKS, and the ssbov is capable of handling my setup. I don't know what the stock or aftermarket diverters are capable of handling, but since the hi-hp Evo kits run the Evo DV's, I'd imagine they are more than capable of handling the flow.
The setup I have now of venting back to intake is ideal for me. I came up with my setup, so I can have it anyway I want. For me, this just seems cleaner.
