Am I making the right decision (part deux).

Hi all, I was going to reply to AlphaOmega's post as I am in a similar position cash-wise, but thought I'd start a new one.. I'd love a genuine pre-IB but the car must be my daily too. I ran a Moggy Minor hot rod for 5 years as my daily (black Lancia twincam on cover of Retro Cars a few months back ...

I guess it depends how original you want to be. There are lots of companies that can match rubber extrusions, grommets and seals at a fraction of the cost of genuine parts. Clearly, this isn't going to work for heavily shaped window seals, but you may find that for other less prominent trim it is ac...

"How do i check the rpm of the engine compared to what is displayed on the tacho??" Go back to the coil trace. You've got a six cylinder engine so it'll fire the coil six times in 2 complete revolutions (unless it's a two-stroke . :lol:) . So in other words, 3 ignition pulses per crank rot...

Sorry, just read "I have also changed the points to pertronix". So does that mean you've got electronic ignition?

If so, there should be a feed of of that to drive the tacho directly. Time to get the Picoscope out again... :lol:

Apologies for the generalisation, but I don't have a 911 :( (yet) so can only comment on experience fiddling with other old motors. There are two types of tacho, older types can be current sensing (RVI) and newer tend to be voltage sensing (RVC). My guess is that Porsche introduced a newer voltage c...

I notice you have Picoscope. Hook it up to the drive signal and post the results here. Try grounding the scope signal in different places and see how the signal is affected. If that has a significant effect, run a temporary ground wire straight from the drive signal source to track the bad ground. J...

Just read this and glad to see some PFunkers amongst the Porsche people - to be honest I was wondering about Bootsy's moniker! To put my trainspotter hat on, I'm not sure there is a wah-wah guitar in "Up for the down stroke" - by Bernie may have one on his keyboard. Check out "I Got a...

Well that's what the Porsche staff told me when I enquired about the colour. Perhaps they meant JK Rowling? :)

It was a deep blue (slightly purple). I was told it was "near" Iris blue but I dont believe that. I have some pics to follow..

Pssst! Porsche staff can't keep a secret.

The '73 RS on the Porsche stand at FoS belongs to Jay Kay but I'm not to tell anyone ok? It's a secret.

Classic Porsche Hire - East Sussex?

Hi,

I'd like to hire a classic 911 to go down to FoS on Friday 2nd July. Anyone know where? Preferably in East Sussex.

Failing that, anyone prepared to loan one out for the day?

Cheers

Jonny

Steel early front wing backdate panel

Hello,

I have seen that it is possible to backdate a later front wing by grafting on the lower half indicator/horn grille section from an early front wing. Does anybody make a new steel "backdating" panel to achieve the same result?
