Mine has a 2.7 bottom end, schrick 288 cam and valves, autronic SMC ecu, a 4.1:1 LSD from an E30 M3 and a set of coilovers. Also has a 5 puck competition clutch, with very little room for slippage. with that and the fat cam it was entertaining to drive in the wet. need high revs to stop it from bogging and can't slip it much, coupled with a tight LSD and taking off involved a bit of a crab walk. A tad antisocial. Also got a sparco pro2000 seat, PWR ally radiator (42mm thick core), camber plates, and custom extractors.
The 02 has cobra seats, sparco FIA roll cage, 4.1 LSD, 45mm DCOE webers, reground cam, bigass alloy radiator, camber plates and KMAC heavy springs and everything I could remove from it stripped out. That car is grandfather's axe. Was on about engine 3, diff 5, gearbox 4 or 5, the only things that were original were the panels, windscreen and rear window, taillights and rear bumper. Subframes, suspension gear, drivetrain, you name it, all swapped out/replaced at some stage.
Between those 2 shitboxes I could have had a very decent house deposit.
