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 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'Replace are modifications' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace are modifications' (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.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

Does anyone have any experience of the following 'Tequipment' upgrade offered by Porsche?
What sort of bhp/torque increase can I expect? It's for my '99 996 C4 tiptronic.
Carrera Powerkit
(For 911 Carrera up to 12/00 only)
Boosts power output from 221 kW to 235 kW using a modified alloy induction system, modified cylinder heads and modified exhaust manifolds. The package also includes an additional oil pump in each cylinder head.
Thanks
Don't know about '99's + but, for my '02 C2, the $12K range(last I heard) for 20-23 HP boost is more than HALF of what I just paid for beautiful/solid '91 C2 w/ just under 70K on it(I'ts just starting to become my full(almost) time DE/auto-x baby).And if... for some reason kiss the Armco....
I'd have ordered the X51? option w/ the '02 ..if I'd known about it then(Nov-01)
Tough decsion..like my local P-car track prep boys/girls say.. Once U start smoking the race/hp pipe... Good luck let us know!

Don't know what the tequipment powerkit will provide in terms of hp gain but I can tell you that the Fabspeed headers, exhaust, and unichip gained me 28hp at the wheel for under $4k.
If/when TPC(Turbo Performance Center)get the 996 supercharger ready for sale you may look into that(claimed 394 hp) but if you prefer oem powerkit is a way to go but kinda expensive for amount of hp gain but to each their own. Regards and good luck. Mike
