240Z L28/3.0 LITER F/GT - FIRST START - GOPR0098
Blind faith and the need for speed. 1973 Datsun 240 Z, HLS30150666 with Rebello Racing 3 liter engine. 2988cc's with 15.22:1 compression ratio, Honda rods, .620" lift, Extrudabody 48mm ITB fuel injection, Stahl 1.75", 6 -2 header and Adaptronic engine management. Dyno tuned it makes 379hp@8200 rpm with stock oil pan. Have since install an Arizona Z Car 6 quart pan with windage tray; a Teflon Ishihara-Johnson Crank Scraper will also be installed. A more detailed video of the end product, a 30+ year project, is on the way. And then, Speed Week 2014 - Grand Touring under three liter.... If you like the idea of a low vision/blind builder/driver setting a land speed record at Bonneville, you can really help me out by liking this video and sharing it. Thank you.
280Z L28 3.0L / Engine Rev and Exhaust Sound
Rebello 3L with ported head, valve train work, and cam. Produced 297hp @ 6700RPM at Rebello's facility. This was about the 3rd start after a light tune.
First start up of Frankenstein L28 with triple Mikuni's
This is a second hand rebuilt L28 engine I picked up. It that has 2mm oversize flat top Toyota pistons (hence "Frankenstein"), 74 deg cam, re-curved mech advance electronic dizzy, extractors with 2.5" Exhaust and triple Mikuni carbies on a Cannon manifold. This is the first start up of it once installed and the tuning is up the shit, but at least it ran. The smoke is from the Exhaust paint curing and is no big deal, looks bad but that is normal for the paint to bake on. Stay tuned for more video's once its finished and running properly.
