It's an S1 Jarryd, 81/82 model.
When you decide to sell it, give me a call, parts are always handy to have.
Your old DR is progressing steadily, got heaps of pics on progress and will start up a new thread when I find the cable to download them off the memory card.
I'm waiting on bits from Fantasy Performance, like bigger turbo, O'ring fuel rail for 770cc injectors, V band dump pipe adaptor, and getting some bits made here in NSW to go with my HKS Hi Mount and 41mm TIAL ext wastegate.
I'm going with a straight through exhaust, firstly through a 3" hot dog, then straight out the left side in front of rear wheel. Ext wastegate is also venting to atmosphere along with huge type 3 Turbosmart BOV. Should make heaps of fun noises on the track.
Cheers, D
