Hats off to you for cracking on with it, makes a change from some long winded builds here changing a bolt a week!
Is that an old mercedes E55 estate in the background?
It sure is... and also one of mine : ) it is a Japanese import, no history, reading 67k km.... ha ha ha yeah right.... having it wound back up to its true mileage as we speak of 179k km.... (got hold of the 2 year 'mot' certificates from Japan to get it corrected as knew it was clocked but was very cheap). Good condition though and has also had some work done. Now looking beautiful (to my eye). Oh tints have since been removed....Is that an old mercedes E55 estate in the background?
Apologies for the Merc pics in a Porsche forum.
Anyway, back to topic. The fuel injectors..... we felt the power was down and thought it could be the injectors getting clogged. Very common problem in the UAE as fuel is not great. 95 octane mostly with 97 at say only 1/3 of stations. No 99. Needless to say i drive out of my way to get the 97 and normally top up with some Liquimoly Octane Plus but clearly prior owners didn't..... this is the state of the injectors!!!!!

Get all the coolant fittings welded while it's out.
I was told about this but after reading the below from Sharkwerks, I have decided against and hence fitting the two kits I gave the links to above. Sharkwerks and EVOMS are both adament this is the way to go. I guess time will tell

Does anyone have a picture of this pinning process described above ?
This is what Sharkwerks provide:http://sharkwerks.com/porsche/technical-articles/3...
Not far off sir. But going to be a little less green and more silver. Silver centre stripe as per the 4.0 RS but with thin green edging. Mirrors kept white but with the lower blade only in green. Silver side decals perhaps witha small touch of green. Green stitching inside and green roll bar. Silver seat belts and harnesses. The rest white.

The safe and easy option on tuning would be to go Porsche motorsport on the diff, engine and brakes. The motorsport 3.8 barrel and piston kit is tried and tested and of good quality. You could change the cams at the same time but to be honest, I wouldnt bother. You should get a reliable 450BHP plus with a decent remap. We raced a completely standard 9973.6 cup in the GT Cup series for a few rounds aginst 997Cups that had the 3.8 upgrade. I think that the drivers were Mike Donovan and Paul Hogarth. I found that the upgrade offered a substantial increase in reliable performance. It is not an exprensive upgrade in relative terms and is reliable. Brakes, I'd go Alcon floating disks or cup on the front and leave the rears as standard. With a Cup or Guards diff, the rears will do a lot less work and you wont need any more performance. Guards will build the diff to your own specification but the cup spec with a little less preload will be absolutely fine, or you could just buy a cup unit and set your own preload. While the engine is out, i'd fit a single mass flywheel. You've already covered off the damping with the KW clubsports. A nice Momo detachable cup steering wheel will give you more feel through your fingers.
That will give you a lovely car and make the driving experience pretty close to a 997 cup on the road.
Hi Steve, thank you very much for this detailed and comprehensive advice. I am far from an expert on this, it being my first build (not my hands doing the work...) and am not technical myself so this is really appreciated. Will certainly look into the above in detail, particularly the cup diff and the 3.8 barrel and piston kit. On the brakes I have the brembo's already so will keep those and yes fully agreed on the single mass flywheel, already in hand and waiting to go on. I have the cup steering wheel and rennline quick release (mostly serving as a fancy spacer to pull it in closer to me) installed already. Many thanks againThat will give you a lovely car and make the driving experience pretty close to a 997 cup on the road.
