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.

Suggestion · Original poster
Gear tooth count is reduced from what Porsche run for wider gear tooth base, making the gears stronger.
Leading evidence: 'Run wider gear tooth base, making the gears stronger' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run wider gear tooth base, making the gears stronger' (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.

Gearbox parts are mostly in. Hopefully there will be some photos of that in the near fiture. 2 piece GT2 RS mainshaft, full set of Guards straight cut gears with LSD and billet cover plate.

For me .. the best picture is below .. the water take off .
That's just a work of art period !
I dream of being able to ally weld like that .. never going to happen though sigh .
I'm away on holiday at the momeng and don't have access to all the details, but this started its journey with me as an £1800 eBay purchase of a complete 996 turbo engine with a dropped valve, which meant a damaged head and a damaged piston. I had thought about having a go at rebuilding it myself for shits and giggles, but sense got the better of me and it was sent to Matt at Fearnsport where it was stripped down and put back together. I'll update the spec when I can confirm details.
New liners and pistons, 3.8l
Ported heads, standard size valves
GT3 exhaust camshafts
ARP head studs and big end bolts
Carrillo rods
997 inlet with 1100cc injectors
Meth injection
IPD plenum with 84mm?? throttle body
Fenderwell intakes
Custom y pipe
Custom exhaust
Custom intercoolers
Big turbos, water cooled
Syvecs ECU
Full pressure and temperature monitoring
Pre and post turbo and intercooler
Coolant pressure and temperature
6 exhaust temperatures
Converted to 2wd
Full Guards gearbox rebuild with LSD and straight cut gears
custom gearing approximately 10% longer
2 piece mainshaft
GT2 clutch conversion with adjustable stop
Triple plate carbon clutch with very light flywheel
Suffice to say, it is turning in to a very expensive cheap engine.

The AN fittings you have added to the lines in and out of the turbo sumps, where did you get them from?
It looks like I'm going to have to chop my lines and this looks like a neat way to save an otherwise perfectly good line.
Plus AN fittings are sexy
A couple of shots of gearbox parts.
The input shaft is in 2 pieces, the part which goes in to the clutch is a springy steel to reduce the shock loading, the part where the gear stack fits is gear steel for strength. Gear tooth count is reduced from what Porsche run for wider gear tooth base, making the gears stronger. Shame to hide it away in the gearbox, great engineering.
