Well, there's a thread on Rennlist, there's some stuff on 968.net, but there really isn't a conclusive thread or place to reference if you want to do a turbo DIY. I understand that is partially because there are a few ways to do it, but perhaps it could be broken down to two separate topics: 8V Turbo DIY and 16V Turbo DIY. I also know that people may not be willing to share for various reasons (liability, end result, etc.). I also know there are numerous individuals who have done the conversion by themselves with success.



I know I may be trivializing the concept, but things like a parts list would be the cat's teets for someone who would like to start amassing bits and pieces.



I also realize I could just call Powerhaus/HMR/etc. and pay for it, but saving 50% or more by DIY-ing it sure is appetizing! Plus, I ain't got that kinda expendable cheddar.



As a side note, we have a young machinist here at work who completely turbocharged his 4cyl Chevy S-10 pick-up. Built/fab'd everything himself and did a very nice job. He didn't go to the lengths of a Powerhaus or anything like that, but he deserves a lot of credit for what he did. I admire him and those who have turbo'd their own cars. Note to self: must grow set of stones!

forced induction on these cars is certainly a subject of varied opinion and approach - thusfar, there is no definitive answer - all of them cost a lot, have complications to one extent or another, require a lot of time, effort, and money (did i mention they are expensive?), and none of them are C.A.R.B. approved - for those of us in california, this is a huge problem - it will become a problem for the rest of the country very soon too



as for a DIY solution, it seems the easiset is a centrifugal drive low boost supercharger - this kind of system would be the easiest to install, and the easiest to manage, if you can keep it cool enough - physical space for the unit has been the problem thusfar, with the only systems available to date requiring removal of the air conditioning



i have a couple of different ideas on how to resolve the problems, but time has not been available yet to work it out - hopefully somebody else will beat me to it and save me the trouble

I think something like this will eventually come about... Board Sponsor RS Barn will have DIY Turbo kits soon. I think we could probably convince Pete to write something up in conjunction with his mail order products to get you everything you need to DIY.

As for CARB approval I know Evo Motorsports still has not received their CARB cert for the 996 and they have sold over 150 kits for $10K many are in So. Cal. Even though the SC has a Carb number it does not mean that it is Carb # is ready for the 968. I went through this with my 968 Speed Force had no intention to get the Carb cert. Since it was easy to pull the blower I had planned on pulling it every 2 years. From what I have read from Evo is that CA emissions testing actually needs to keep the car for a few months to do the testing and there is a high cost to get the certs completed.

the process is not cheap - you are right about how it is done - starting the process for the first time is much more expensive than extending a cert for a particular application though - that is why the 2 companies i am working with might work out - they both have full CARB certs for specific applications in other cars - that means they only need to get the extension of the cert for this car - this is a much less expensive and time involved process



we'll see how this all works out - i likely won't get to it until at least the fall though - crossing my fingers at this point

Luckily, CARB hasn't been wrought into law here on the right coast so I don't have to worry about it now. I would also assume that if I were to install the equipment prior to CARB being written into law, and be able to document it, then I don't think there would be an issue. Look at all the old gas guzzlers that get exemptions for having classic and antique plates- I guarantee they puke out more harmful emissions than any turbo'd 968 around. Besides, I will most likely be able to get classic plates pretty damn soon- hello exemption! Classic plates in PA are 10 years or older with limited production I believe. I will have to check on it soon!



That said, I think a definitive resource for instructions on how to turbo your 968 would be welcomed by many, myself included. Caveat emptor, of course.



Longevity should not be an issue- turbo or not, a neglected or abused vehicle will fail. A well maintained vehicle, turbo or not, will last longer than most consumers will require. That's a no-brainer. Done right, a turbo application should only pose small amounts of stress over and above a normally aspirated variant.



I hope RSBarn does develop a DIY kit.... I live about 20 minutes from them so I'd be extremely interested in what Pete can do.



That said, there is this small section of me that longs to do everything myself- from sourcing, fabricating, installing, and testing.



Go check 968.net- Tate turbo'd his cab and has been running it for a year. George turbo'd his cab and is very happy. Others have done likewise. The supercharger just isn't for me. I like the feeling from a turbo.



I would just like to see more people encouraged to share what they have done so that others who dare tread the same path can benefit.



BTW- Will be posting my Tornado test results within the next week or so......

if the other states do it like california, the parts aren't exempt, no matter how long they've been on your car - it's all about the year of the car - however, parts purchased that later get CARB certs can be retroactively certified - there was just a BMW intake system that went through this - all the old buyers had to do is send a copy of their receipt and they would be sent the certification tag so they could smog their car



even out here, the inspections are only every other year, so you could concievably go that long as long as you avoid the "on the road" spot inspection vans



i talked with pete today - i'm also excited about the project he is working on - i'm going to try to help him get the certification - i'd love to see it happen
