ice Needed on Front Shocks/Struts, Koni/Boge, Early vs. Late Options

[andys]

Got one good opinion "over there". Soliciting others.

I've got two options on shocks if indeed they are interchangeable. I'm doing a 911 front swap from a '89 Carrera. These are Boge struts with gas shocks; the black ones in the photos below.

When I disassembled the 914 struts, I found Koni adjustable inserts. The red shocks in photos below.

Should I consider trying to adapt the Koni inserts into the Boge struts? I seem to recall someone did a nice write-up on the different interchanges, and I think Koni inserts fit the Boge struts with a certain mix of parts (retaining spanner, spacer, etc). Since I have a machine shop, I can make whatever spacers I need if the adaption is even possible or worthwhile.

Another question I have has to do with which shock would be better suited to my setup. My car is a LS1 V8 swap with 6 speed trans. I have Koni double adjustable (Yellow) rear coil overs with 200# springs, Engman chassis stiffening kit and suspension ear reinforcement. The front T-bars are stock Carrera (18.8mm?). I would prefer to get the shocks reasonably close to matching the T-bars and the weight of the car. This is mainly a street car with of course a couple of visits to Willow Springs for a HPDE or two. Opinions?

Thanks,

Andys
