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 hose from the AOS:


At first I had a problem with the throttle linkage hitting the hose coming from the rear of the intake manifold as seen in this pic below:


It turns out that the throttle linkage can fit in two different ways - this is obviously not the correct way! 
With that sorted (below) and the (ASH) silicon hose rerouted there were no longer any clearance issues so I tightened the hoses up and blocked off the water connectors with some neat little end caps.


Looking good!


All neat and tidy. Next up will be the AFM and intake boot.

Engine out the top - Easy Peasy

After reading numerous posts, the Porsche workshop manual and Clarks Garage step-by-step engine removal guide - I felt confident enough to tackle the job. But I wanted to remove the engine from the top.  As I discovered, it was pretty straight forward even for a novice! Result. I wanted to avoid removing the cross member and disturb the front suspension to do something I was convinced could be done easier from the top. Posts such as this one convinced me to give it a go at least. And I'm glad I did. In summary I was able to remove the engine from the top without needing to remove the bonnet/hood; torque tube; transaxle; bellhousing; clutch; clutch slave cylinder; cross member; front suspension; and radiator. Contrary to many so called internet experts opinions and many confusing threads this was painless and without dread. All that was necessary to remove was the starter; power steering pump and alternator (I figured to make the bottom of the engine narrower); intak

New Steering shaft bearing Nightmare removal

In my quest to tighten up the handling on the 944, I bought a new Needle Bearing from Porsche in an attempt to eliminate the fore-aft play in the steering at the top universal joint. The part number for the replacement is 477.419.059 and costs £88.86 posted from an OPC. Nothing like the effort required to actually remove the old one... I began the process by reading section 48 of Porsche Workshop manual. It appeared a simple enough process but two things bothered me: firstly, it required a chisel to remove a shear bolt (which in my limited experience never "shear"; and secondly a drill to remove two screws from the ignition lock. I was bothered because a quick look under the dashboard made it quite obvious that whoever had written the manual hadn't performed this task - well not without a dashboard in place that's for sure. I was bothered before I'd even started. Furthermore, the manual doesn't detail the replacement of this bearing at all - just the rem

Bellhousing & Clutch fork removal

Removing the bellhousing from the Porsche 944 engine is not as complicated as it may seem - such as in this situation with my replacement engine. When I removed the original engine I detached it from the bellhousing in the car and removed the clutch pressure plate bolts through the starter motor hole - see my other post for details . In this case I decided to remove the clutch fork pivot shaft bolt. Begin by removing the four 17mm bellhousing bolts - you'll find that the bellhousing doesn't detach completely from the engine. It'll feel like its hooking on something. That something is the clutch fork pivot shaft inside the bellhousing. The bellhousing will be loose enough to rotate - turn it 180 degrees and peek through the access port which is now on top - this is what you'll see: If the engine is still in car you'll be looking at this from underneath. The pivot shaft needs to be extracted from the clutch fork. It's held in place by a small bolt on the
