    The Oil Thread

    My concern would be the 10w60 weight, I'll stick to Penrite HPR30 (When I get it back on the road)

    the clutch job

    if the clutch fork bearing shaft has wear grooves, you can grind another flat 180 degrees round wear grooves 180 degrees around there are no wear grooves

    A over ripe banana

    Wouldn't it be easier to modify the sump than to modify the bulkhead?

    A over ripe banana

    Cool project, After my engine mishap, I thought about doing a 3.6L Cayenne (VW VR6 lump) swap, but decided to rebuild

    Replacing 944 S2 front bumper with earlier model's

    Now you're just being padontic
  6. I looked at the new option, bit confusing with all the part numbers, Have you looked into a 2.7L block, I have a few leads, They are cheaper and more plentiful, plus if you buy a long block, you can sell on the head, (turbo guys love it) who are you getting to do the sleeves, are you going iron or Nikasil coated Aluminium? Here's the link to a new Short block, https://www.germanoemcarparts.com/oem-parts/porsche-short-block-944s2-94410090206crx
  7. Good luck, Rare as rocking horse S**T

    My 944 Cabriolet

    Just a quick update as to what is happening with the cab. First off, Piston manufacturer have not accepted responsibility but have issued me a full refund and discounted set of replacement piston (details of pistons to follow), I'm not going to get involved in any mud slinging online, but i have my opinion which is shared by numerous "knowledgable" people. I'm ready to move on and rebuild the engine (again) and here's the plan, I have a new set of Wossner 104mm forged pistons coming from Karl at Racers Edge (who I can highly recommend as not only knowing his stuff but is an honest and helpful person) The block is being shipped to Electrosil in Melbourne, it's going to be bored out, Aluminium liners (3mm wall) with a Nikasil coating are then fitted, the Nikasil is then honed to 104mm, as an added security the original bores have a lip at the bottom to stop the liners from possible movement AND they are also bonded to the block, I'm happy that this is the best way forward I've have also removed all the (rusted) bolts on the rear suspension (with only one sheared bolt) in preparation for the fitment of 26mm torsion bars to match the (approx. 200Lbs) H&R progressive springs up front On a side note, I'm hoping that the next time my dad comes to Aus, He and I will be participated in the Targa Tasmania Tour, the Targa tour gets to run on the same (closed) roads as the real Targa, But have to keep under 135KPH (or posted speed limits, YEAH RIGHT), so no timing nor racing and hopefully no crashing or breakdowns, Just six days of spirited driving on closed roads with no oncoming traffic

    Alusil cylinders recoating

    Just a word of warning when things go wrong, An Alusil block honed by proper procedure, pistons designed for Alusil cylinders, Something went wrong within 150Km's 2 out of 4 piston/bores are rooted, other 2 show signs of (very) early wear/galling

    Recommendation for dashboard reskin

    https://www.dashdesigns.com/ Just tell them (via email) that it's a RHD car they need to flip the material here's a thread I started (but no interest) I love mine, I got the Sedona Suede one Here's a group buy thread I started but no interest $145AU delivered, pricey but feels and looks quality

    My 944 Cabriolet

    Here is the procedure that was used on my block (original PDF at the bottom of post) INSTRUCTIONS FOR HONING HIGH SILICON ALUMINIUM ALLOY ENGINE BLOCKS – ALUSIL Engines: Chev Vega 2300, Porche 928, 928S, 944 Mercedes Benz 3.8L, 4.2L, 5.0L, 5.6L, 6.0L V12, BMW 750i M70 V12. INTRODUCTION One of the most significant features of these engines is the use of an aluminium die-cast engine block that does not require a steel or cast iron liner in the cylinder bore. Pure particles of silicon, averaging .001”(0.03mm) or smaller in diameter, are dispersed in the aluminium alloy throughout the engine block. To achieve the proper surface for ring and piston compatibility, the cylinders should be prepared in such a manner that the silicon particles protrude from the aluminium so the piston and rings contact only silicon. Because silicon is very hard, there will be very little wear in the cylinder bore. In fact, as far as the piston and rings are concerned, the cylinder wall is a silicon wall, and the aluminium’s function is merely to “hold” the silicon particles. If the cylinders become excessively scorn or worn, they can be reconditioned with either automatic or manual honing equipment to accept oversize pistons. However, the usual sizing and finishing operation leaves a cylinder wall of silicon AND aluminium - - - the silicon does not protrude. Therefore, a special “Conditioning” operation is needed to remove aluminium from and between the silicon particles so the silicon WILL protrude. This is the reason for the Conditioning operation which follows the honing operation, explained in detail in these instructions. USING SUNNEN AN111 PORTABLE CYLINDER HONE GENERAL T ooling AN111 Standard Cylinder Hone AN80 Quick Coupler UN60 Universal Honing Stand 5/8” Chuck Electric Drill 200 – 300 Rpm Stone Sets: MM33J63 MM33J85 MM33C05 Felt Set: MM33F05 AN30 Sunnen Silicon Compound AN35 Storage Box GA2125 Dial Bore Gauge Flood cylinder with MB30 Honing oil throughout each honing operation, using a continual spray pump or applying continuously with an oil squirt can. Failure to use enough oil will result in stone loading and possible scoring of cylinders. DO NOT use honing oil on the final Conditioning Step. HONING PROCEDURE NOTE: Figures for stock removal rates, Stone wear, and Surface finishes are general information only, and are all approximate. CAUTION: To avoid hitting main bearing webs and damaging stone sets, use a mild steel or aluminium washer in the bottom of the cylinder. 1. Roughing Operation – using MM33J63 Honing Stones a. Hone to within .003” (0.075mm) of finish size. Brisbane Head Office Unit 1, 22 Hugo Place Mansfield Brisbane 4122 Phone 07 3420 0844 NSW Branch 5/12 Donaldson Street, North Wyong, NSW 2259 Phone 02 4353 5551 (1) Stone MM33J63: remove the top 1” (25mm) of honing stone. (2) Stock removal rate: approximately .0035” (0.09mm) per minute. (3) Stone wear / Stock removal ratio: 1 / 1 (4) Surface Finish: Ra 25 – 30 microinches (Ra 0.6 – 0.8 mirometers). 2. Finishing Operation – using MM33J85 Honing Stones a. Hone to within .001” (0.025mm) of finish size. (1) Stone MM33J85: remove the top 1” (25mm) of honing stone. (2) Stock removal rate: approximately .002” (0.05mm) per minute. (3) Stone wear / Stock removal ratio: 2 / 1 (4) Surface Finish: Ra 15 – 20 microinch (Ra 0.4 – 0.5 micrometers). 3. Polishing Operation – using MM33C05 Honing Stones a. Hone to finish size (1) Stone MM33C05: remove the top 1” (25mm) of honing stone. (2) Keep the cylinder hone feed pinion tight. (3) Stock removal rate: approximately .0007” (0.018mm) per minute. (4)Stone wear / Stock removal ratio: 2 / 1 (5) Surface finish: Ra 4 – 6 microinch (Ra 0.1 – 0.2 micrometers). 4. Conditioning Operation – using MM33F05 Felts Wipe cylinder clean of any abrasive or foreign matter from preceding operations to avoid scoring or scratching cylinder wall. a. Saturate MM33F05 Felts in honing oil. b. Mix Sunnen Silicon Compound thoroughly. c. Coat Felts and entire surface of polished cylinder wall heavily with Compound. d. Condition first cylinder as follows: (1) Tighten feed pinion wing wrench as tightly as you can with fingers. (2) Condition for 1 1⁄2 minutes, stroking with 1/8” (3mm) overstroke. (Longer overstroking tends to cause ends of Felts to wear faster, this may result in uneven conditioning). USE NO HONING OIL – it would wash away the Silicon Compound. Periodically tighten the feed pinion. The cylinder will have a dull matte finish, approximately Ra 12 – 18 microinch (Ra 0.3 – 0.5 micrometers). There will be no significant stock removal. CAUTION: Be sure to replace Felts as required to avoid metal holders making contact with cylinder walls. Must be replaced in sets only. e. Repeat steps c & d for each cylinder. NOTES: When not in use, the Felts should be stored in the Sunnen AN35 storage box to avoid contamination. Sunnen AN30 Silicon Compound is a carefully formulated substance and should be kept free of any foreign matter. Use only clean brushes and do not attempt to reclaim any of the Compound from Felts or cylinder walls after conditioning. If presently using CK50 Honing oil, use C30A53 honing stones. MB30 Honing oil reduces the possibility of damage to cylinders due to stone loading. Watson.pdf

    Thanks Bruce, There is a very feint cross hatch on it, but nowhere near as much as on iron liners. here's a photo of a section of untouched cylinder

    944S2 engine/block wanted

    Severe engine failure 150km's after a full rebuild has left me devastated, so i'm exploring options while the piston supplier does an investigation,I'm looking for a 944S2 engine or block/crank cradle/balance shaft covers with (preferably) good bores, Cheers Steve
