My L24 makes 150hp at the wheels (maybe 180 or so at the flywheel). It has weber DCOE40s, a header, mild cam, and a Rebello road race L24 (bored, E31 head, mild tweaks). Mr R says 217 flywheel, 180+hp wheels is carb tune and cam away. Planning it out now. I built a harsh z early on. Konis, big bars, lowered, etc. Too rough for anything over 20 minutes! This one has european spring rates and chassis weight has been lightened. Gas struts and a '74 rear sway bar. 4 piston fronts with zx master cyl. Rides firm and is well in control of the motor. Not harsh, but quite firm on any extended drive. I'd ride in a few to see what you like.
