Setback! Ring gear bolt snaps...

At this stage the last thing I needed was a snapped bolt. The ring gear is bolted to the flywheel with 9 pan head screws. Supplied by Porsche I wasn't expecting any problems bar the challenge of aligning the three sets of offset holes on the flywheel and ring gear on the clutch pressure plate. Inserting the bolts through the starter motor hole in the back of the bell housing is awkward enough but very difficult to align the three sets of three holes (more on this later!). I had my son turn the crank shaft via a long breaker bar while I inserted a pencil into the ring gear hole to find the corresponding threaded hole in the flywheel. Once I thought I'd figured out the sequence I inserted the first 6mm Allen head screw and began tightening it up. When it was tight I then gave it a crank with the torque wrench and twang! Snapped bolt. To say I was upset is an understatement. I could immediately envisage pulling the engine to get access to the remaining part of the bolt

16v S2 Throttle Body

I'm fitting an S2 intake and throttle body to my 2.5 16v. The S version is quite a lot smaller than the S2 - why I'm not certain. There seems to be many theories just as there are with the different intake versions - honestly the S2 version looks much better and according to guys who've done the swap with the 16vS cars it makes a difference. If the size of the throttle bodies is anything to go by - there's a lot more air going into the intake which can only be a good thing! I mean the difference in volume is like a big gulp and a sip! I mocked up the throttle body and S/S2 AFM I sourced - as my car had an 8v head the AFM is different - whether the internals are the same or not I'm can't say for sure but the Bosch connector is identical. It will be interesting to see whether the 16v S ECU will run the engine with the 8V version of the AFM... With the S2 intake bolted up, I offered up the S2 throttle body to the intake manifold and connected the h

Fitting the intake begins!

Ah yes sunny summer is over and TheHoff was beckoning from the garage on the weekend, so I ventured in... here's what I've been up to!  I solved a couple of my "what the heck connects to this?" issues I was having with the engine harness. The big round connector...  ...needed this resistor plugging in - got it off a bloke breaking yet another 944S (they're going to disappear soon at this rate) With that plugged in I dared to look under the gearbox at the rear and saw a great big oily puddle... ...this had more than a little perplexed as TheHoff hasn't been on the road except when I rolled it down the drive and onto the back of a car transporter when I moved a few months ago... the fix was easy (I hope), it turns out (hahahaha) that I mustn't have tightened the gearbox drainplug properly when I did an oil change - but that was 2 years ago... :-/  Anyway it's all tight now - only a spirited drive will tell if the gearbox has se
