"...seller is a bit odd though."
so are buyers.
as to spec & craftsmanship, "penny wise & pound foolish" comes to mind. a paint job won't help the value / resale equation either. I agree that a 944 conversion makes more sense (& it's a Porsche!), since the whole 924-928 family was a kinda "Porsche makes a Vette w/ back seats" exercise anyway, wasn't it (& it's a Porsche!!!)? regardless, who was it that said, "Do what thou wilt."? yes, we must all exorcise our demons.

conversion
i have a sbc conversion and really like it...i should as i built it for me and no one else. it is built on a 71 911 chassis with rs flares. it has a dart all aluminum 434 sbc engine making 585 at the crank with 9.6 to 1 compression. engine weighs almost the same as the early engine and less than a 930 engine. i use 930 gearbox, kep cluth and pressure plate, lindsay wheels, big brakes, aluminum roll bar, period correct recaros, aluminum cross member and trailing arms, properly converted gauges, adjustable sway bars, oil cooler, lexan rear and side windows, etc. runs as fast and straight as i need to go and performs as well original and with better weight distribution...car weighs 2200 pounds and looks nice and well sorted. i would sell my 425 rwhp '78 930 before i would sell the 911! the 434 has forged internals and is easy to add a 200 shot of nos!

guys, you are all looking at it the wrong way. dig deaper and think of it the other way around. It's a chevy that got a Porsche body. It doesn't hurt as much that way.

this is a picture of the conversion...if i downsized the file properly. by the way, at no time during the conversion did i consider what is it going to be worth if i ever sell...there are many aspects to having high horsepower in a lightweight car that are priceless...

impressive, max.
did you keep track of costs, the hw / labor split? would be an interesting data point. I'm always curious about thermal load w/ sbc conversions, ie does it cool adequately at peak torque in top gear until fuel supply is exhausted? or perhaps your application doen't require that type of operation? overall, how did you address cooling?
"with better weight distribution"
do you mean more towards 50/50? I am not one who assumes 50/50 is in all cases better, so specifics help. thanks.

no, i did not keep track of the time and i suppose over time one realizes that the wallet is lighter...these type of projects and expected results are some what of an addiction it seems to me....and many on this forum seem to suffer the same malady!i knew what i had in mind when i commenced the conversion and got what i had in mind...perhaps more. cooling is not an issue for me but i do not track the car...it is my daily driver and would not hesitate to travel at any time. car with 930 gearing cruises at 70 mph at 2200 rpm...hence not a buzzy car with lots of resonance. radiator is a properly sized griffin all aluminum with two 14 inch spal fans which are thermostatically operated or manually. the oil cooler is located in the right passenger seat well and vent to the bottom of the well. the cooler is enclosed and fed air by two 3 inch naca ducts in the right quarter window. weight distribution is more 55/45 with bias to the rear. with 9 inch by 17 rear lindsey wheels with 285/40 by 17 tires traction is very good and the 930 transaxle is llimited slip. the dart all aluminum racing block was a bit pricey and if i was to do it again i would use one of the lsx sbc which are in plentiful supply and relatively cheap and with factory efi.

the motor alone was slightly in excess of 10 grand... so it is not a cheap conversion if done properly....but much cheaper than the dollars necessary to build 600 hp in a porsche engine, not to mention maintenance and ease of build! the rest of the conversion was similar to what most of the other guys expend to modify their suspension, body, interior, wheels, brakes, etc. of course the short 930 transaxle ain't cheap but neither is a modified 915 or and certainly not a g50.
