one-off super cheap "custom" solid-rubber engine mounts....
fitting projector lights to the fog light position, to use as headlights...also coming up with decent looking clear lenses
fitting a 928S3 head to a 951 short block, with 968 belt drive, modified 944S cams (coming back from the grinder soon), and S2 intake manifold (until i build a custom one for the supercharger)
and the long-running supercharger project...currently waiting on the machine shop to send me my custom pulley (to run low boost in 8v setup), although depending on time frames i may skip running 8v altogether and just go straight to supercharged 16v.
...or do you want the "RS-ish" interior redesign with felt carpet and soon to be modified-and-refurbished dash and door panels? no pics yet.
...soon to be building a new DME harness...and then a new full-car electrical system...
Don't have any good pictures right now but my 3L-16V with Darton MID is ongoing and the head (944S) is almost finished, going to change intake valves to 39mm and new harder valve springs+retainers. Ordered new cams this week: http://www.catcams.com/products/cams...MSETUP_id=1050
Installing new ECU, 3 x larger Setrab oil cooler, boxing in the IC+radiator for better cooling efficiency, Fuelab fuelpump with variable speed control + FPR.
New turbo Holset Super HX40 with upgraded turbo mount, Twin entry crossover pipe is also under construction.
I´m also going to logg: 4 x EGT, lambda, fuel and oil pressure, wastgate opening with the new Turbosmart wastegate sensor, 2 x oil temperature, temp before the IC
The project is expanding all the time but hopefully the engine can be mapped in the end of August. I will post more picture of the engine build when the MID:s are finished
Sunroof delete 85.5 NA with 89 turbo S late offset, OE turbo cup suspension, 2.7 block, 968 head, modified Andial 104.5mm pistons, EFR7670 internally wastegated twin scroll turbo,Clewett trigger system, Haltech PS1000/Logger dash/CAN wideband/LS2 coils. Full wine red leather interior with sport seats, 968 mirrors/handles, as uncluttered&stock apperance as possible.
Latest major project consisted in tightening the various rods for the locking mechanism in the passenger door, which cured a small but PITA vibration that occurred when accelerating below 2000 rpm. It cost 1hr to solve, which has been extremely satisfying. Next project is to reglue the glass on the hatch. Exciting, isn't it. I guess I'll get my coat now...
Re-finished seats came back from the upholsterer this week, door cards are next. Once this is wrapped up I'll start doing my research on a stroker and/or 16v setup.
...the head (944S) is almost finished, going to change intake valves to 39mm and new harder valve springs+retainers.
proceed carefully...the 928 guys (with almost identical heads to 944S) find that they LOSE intake flow by fitting 39mm valves without hogging the port out to match.
the 968 intake port is SO MUCH BIGGER that it is shaped right to use the 39s...the 944S/S2 isn't.
So far I haven't seen any need for doing ANY sort of modifications for 944S/S2 head, it just flows so generously from the factory.. It just adds tons of cost and that money could be instead spent on Darton sleeving or flat decking the block and buying stronger and lighter piston/rod combo. And Making a dry sump system too, there are no other weak points on the engine then, really.

+1 the ports flow so much more as stock and the valve curtain area is minimum 30% more than the 8v heads...
do a google on what other engines use 37mm intake valves...S2000, new Ford 5.0, etc...stuff that makes a lot of specific output NA, only gets better under boost.
legend has it that the combustion chamber design/shape (along with the valves and all the other parts) of the 928S4/944S heads, are what they used on the 959 heads as well.

It would make perfect sense as the development was already done for 4v application and as any company, Porsche (especially) was counting money so why not adapt it to other models.
Besides, the fact that it flows so well and has excellent knock resistance speaks for that connection between 959 and 944 16v heads, I don't think they would have put so much effort onto it if it was purely for 944.
I have often wondered how come they put such a good head onto normally aspirated engine, such a waste
