Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
I'm not 100% on this but I believe you need to purchase a 987 or 996 plenum thats why you have to use the 75mm throttle body which is stock on a cayman and 996 - you need to find someone who has done it allready, I have a TB waiting but have not had the time to spend $900 for a possible 5 hp.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Im having a little trouble looking for a IPD plenum. I have a 01 S and I recently bought a 75mm throttle body to go with the plenum. Does this plenum fit other models of porsches? Do I look under a different model that will fit mine? Thanks

I'm not 100% on this but I believe you need to purchase a 987 or 996 plenum thats why you have to use the 75mm throttle body which is stock on a cayman and 996 - you need to find someone who has done it allready, I have a TB waiting but have not had the time to spend $900 for a possible 5 hp. what you can do is go to Pedros garage and see what he has to offer, I just bought one from him and am about to install it, let you know how it works. I have talked with at least 2 people you have installed this and said it worked very well http://pedrosgarage.com/Site_2/TechnoTorque.html

George, I've got the IPD Plenum. What you'll need is a modified 3.4L Cayman plenum. The nipple is modded (larger) for the 986 boxster, and one other portion is also slightly modded. Mate that 75mm 996/987/997 throttle body to the cayman plenum, and you'll also need two reducer silicone hoses and clamps for the plenum to connect to the manifolds. From there, you'll also need either your own custom piping/hose, two IPD cayman hoses mated by a pipe, or the new IPD boxster hose (one piece proper fitment). I'll have some updated pictures soon, as I'm one of the first with the new one piece silicone IPD hose for the 986. Here is a picture of the current/temporary setup. .............
