I was running into dead ends with the LSD. I couldn't find anything short of a $1600 Quaife or $800 Mugen diff. Well that's more than I paid for the car, so I looked elsewhere. I ended up finding a
Phantom Grip style clutch pack on Ebay for $150 and bought it.
The idea is that you stuff this thing into the diff, put the pin through it, and undo the clips. The springs then push against the spider gears creating a locking effect. When torque is applied accross the two wheels, the pin through the center twists and pushes the clutch packs into the spider gears even more....at least this is what I think. It seems to work, but we will have to wait until I get the car running before I know whether it works or not.
I just wanted to chime in with my review of the Phantom Grip LSD before you go any further with your build.
I installed one of these in my tranny and was somewhat dissatisfied with the results. My PG LSD would arbitrarily slip, making the car unpredictable in turns. I feel that the PG LSD was the biggest waste of time and money that I put into my 1G CRX build. IMHO, the PG LSD is OK for a street car but is not suited for competetive driving. If you check the Kakabox thread, you'll see that KAKA' ditched the PG LSD he inherited from me and installed an OBX LSD. The OBX costs around $400 and is well worth it. BTW, the PG LSD hasn't been nicknamed the "Phantom Slip" without reason.
You might also consider swapping your rear coilovers for a set of Ground Control coilovers sometime in the future. I've seen the brand you are using up close and I was not impressed with their quality when compared to other coilovers on the market. There seemed to be fitment/slop issues that made me doubt their effectiveness in a competetive racing environment. Again, OK for the street, not so good for racing.
Other than these two issues, I think you're on your way to a great build.
Good luck!
