The car ran ok at wot it was noticeable maybe been beter with a decent tune.
Leading evidence: 'Run ok at wot it was noticeable maybe been beter' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run ok at wot it was noticeable maybe been beter' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Maybe JimB or other racers would have some insight...but I think he's running an X51 3.6 in his car now.
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.

You have to ask is it worth the money to do the cams. The labor to replace them and consider the cost for a new ecu will run you at least $4,000 or more for labor and a new ecu in addition to the cost of the cams. I suspect that there is no more then 35 HP at most so its a pretty expensive conversion. Also consider sometimes cams just bump the HP in the upper RPMs so you won't gain any real day to day power since we spend most of our time under 5000 rpms.
$4000 for labor to swap cams??Yikes! @ your base $100/per hour labor rate, thats 40 hours! Theres no way it could take 40 hours to swap cams.
I am also considering this for my 3.4 swap into my boxster. I think FVD automatically does this when they do their swap, and they reporgram the ecu to account for the hotter cams, and they say it does make a nice, noticable difference to the butt dyno.
does anybody have them in their 996????? Inquiring minds want to know? How much did it cost to install em?
I put a set in a customers cars once i dont know who made them, car didnt idel all that well after or even drive ok at part throttle , he was supposed to take it somewhere and get it tuned (chipped) but I dont think he ever did. The car ran ok at wot it was noticeable maybe been beter with a decent tune.
Labor thorugh the shop 28 hours would about do it.
Bump. Sad this thread got burried over the weekend. I'd like to see more threads like this and like to hear anyone else's feedback if it exists.

Let me chime in hear and advise you to never install a camshaft that the salesman cannot specifically tell you what is different about his cam vs. your cam. Most of the emission compliant profiles have a slight increase in lift to accomodate a little more duration, the increase in lift is to skirt the trajectory issue with the duration increase. After the duration has been increased the lobe centers need to be spread apart so that the overlap will not effect the emission readings.
If someone cannot explain this simple paradigm don't but his stuff. They even cannot tell you these things at PMNA make them so you don't end up with something that is worse or at best equal to what you have.

Depending where you go, labor cost will be between $ 2,500 to $ 3,500.00 for labor. But please keep in mind, unless you have headers, sports cats, and the proper software program for this upgrade, don't waste you time. Properly installed with all the parts you need , you will see 50 to 55 HP more @ the crank.
Park Place Porsche did a few power kits with the cams a while back. Contact Randall Johston if you need input on the cars they did.

Thank you. I've done everything but the cams, however maybe my software would need an update? Has anyone tried the FVD throttle body upgrade? That was another thing I've been pondering.
hey guys, i had been reading the header/exhaust thread before I took a look at this one and I was thinking exactly the same thing as GREEK-TURBO-RACER. I've done alot of engine/exhaust development work and it all works hand in hand, a stock engine with race headers/exhaust may not pick up that much. Once you add cams, then the headers and exhaust start to add more to the whole package. It's my opinion that the increased scavenging effect from the headers helps more then the camshaft profile is more radical, and has more overlap.

If you ever read the manual for installing the cams, you start sweating just thinking about how much work it is and the kicker, special tooling to install the cams. There is a lot of special tools that AutoZone doesnt carry, lol.
Forgot to mention about the special tools. Without the special cam tools to line them up properly for each bank, there is a BIG risk to bend the valves and further damage the motor. Yes ... this has happened by shops who THOUGHT they knew how to install them. Even some dealers have had problems . Park Place Porsche though had no problems.
