Reply to "Suby Conversion Tranny Whine"

Just FYI: 993 engine is just over 550lbs, but once we "undress" them and backdate parts to mate with a 915 we can get them down to 510 lbs, a little over 2x the weight of a T1 VW and 2x the weight of a Subaru.  The 915 gearbox is just under 150lbs, almost 3x the weight of an IRS T1 box.  The earlier 901s will save nearly 50 lbs over a 915.  The 964 3.6 is a touch over 600 lbs.  Plus you have an additional 11 quarts of oil vs aircooled or Suby... but you just cannot compare the sound and feel of the 911 6 cyl... Mmmmmmm...

@Arden Jimmy's conversion timeline was pretty much average when worked into our "normal" schedule.  We had Meade's car here a LOT longer but I brought it into one of our "winter service" slots thinking I could work it in easier, and it just took much longer to even start the project than expected.  I'd say his car sat in the warehouse 6 months before much even happened.
As for cost, nearly $5k of that goes into the gearbox.  We've had a couple of guys do conversions on a stock pro-street transaxle, but they just don't hold up, so we require stepping up to a pro-drag box with Subaru matched gear ratios.  The way we do the  motors is certainly not cheap, but you wind up with a brand new OEM short block, all OEM gaskets, machined/decked heads, powdercoated top end parts and all new OEM consumables (plus a new water pump, tensioner, oil pump, timing belt). Not fool-proof, but as close as you can get to a new/crate motor from Subaru.  There are also a handful of"trick" weave learned over the years that we implement into every build (like shimming and polishing the oil pump for example).

I'd say the number of Subaru builds (speedster, spyder, coupe) are approaching 70% of our build schedule these days.  The 904GTS is still all aircooled Porsche (with a few custom water-cooled Porsche in the mix) but I know we'll get  aSubaru GTS request some time... LOL Quite frankly, I think and STi 300hp GTS build would be fun.  Same HP as a 993 and 300lbs weight savings...   :-)
