  1. waiting parts. Pistons to arrive soon.....I dropped the crank off at the machinist to check it all out.
  2. Do you have a Z with you over in the P.I. ?  I hope so!

  3. I just returned from a vacation in California. While there I went over and talked to Deve Rebello. I know you work with him on these heads. A short talk with him sold me on your Datsunworks head over the OS Giken head. Keep up the good work!
  4. Thanks a lot. I am just having fun wiht it. I know this one will stay with me. I am so happy I have it. Very blessed.
  5. Hello! I need an R180 rear differential, 3:90 or 4:11......no LSD is fine, Need one that will bolt right in with my 240Z bolt in half shafts. PLEASE help!
  6. 11-23-2022 UPDATE. I jumped off into the deep end yet again. To go with my stroker engine.......I bought a 5 speed manual trans! I already have the pedal box for a manual trans. I can buy a brand new conversion kit from Godzilla raceworks. I was going to just get a 4 speed since they are so much cheaper, but at the last minute I decided to do this. It is out of a 1980 280ZX NON Turbo car. So, it is the desireable close ratio unit. There is a shop in Colorado Springs, Precision Transmission, who will rebuild it for me. Crossing fingers as some parts are NLA ( no longer available).....so hope fully the bearings and syncros are all that will be needed. Also went ahead and got the engine plate for manual trans. Dirty as heck.....needs my "golden touch". Other than the conversion kit, I need, a shifter, a couple of shifter boots, inner and outer, and a new starter.......would be nice to get a NOS one, who knows. Anyway, that's the news..... here are a few pics of the stuff. I got it on eBay.
  7. A lot of work down here.....doing yardwork to help out......I had to make a fun day.
  8. Have any of you had luck with a twin turbo setup on the L series. Seems that 2 small turbo's might help with lag and really provide a movre livable street setup
  9. 11-17-2022 UPDATE: I found myself in the Bay Area for a few days, so I took some time and drove out to Antioch to meet Dave Rebello and his crew. Very nice guys, and the tips for building my engine were extraordinary. 50 years of doing this means a lot of good knowledge to gain. While there I picked up the Harmonic Balancer I need for the stroker crank and checked up on the pistons. Guys were so nice they took the balancer into the back and honed it.....for street applications, Dave said it needs to be honed.....when I told him I would hone it with my drill on my leg he handed it to one of his guys and they went and did it proper! Pistons almost ready. Amazing that the quality control is so good nowadays. The chief engine builder, Mark, was telling me the last 20 SETS of pistons from TRAUM, all rings were to spec, and DIDN'T even need to be filed to fit. INCRDIBLE! Also saw out front awaiting shipment a 2.5 stroker heading to europe, 13.0 to 1 compression race engine, Dave told me numbers and I don't remember but it was WAY more than 300.....almost 400. Mark said from idle to 8000 it is a beast! I also snapped a pic for a dyno chart from a 2.7 street build he did that showed torque way above 200 all the way across.....I hope, I hope!
  10. Thanks. I am trying to. 11-17-2022 UPDATE: I found myself in the Bay Area for a few days, so I took some time and drove out to Antioch to meet Dave Rebello and his crew.

  11. 11-4-2022 UPDATE. I have ordered more parts for the engine build. I got some NOS Nissan main and rod bearings, a cleaned up and restored front cover, New Nissan NOS oil pump, New NOS Nissan water pump, and in talking to Dave Rebello, found out that these V07 Diesel cranks don't "like" stock harmonic balancers.......He sells a single pulley variant of BHJ harmonic balancers which have been designed and are successful in handling the harmonics that the extra stroke brings to the table. He also stated that for some reason, 6400 RPM is a point where the engines show a great deal of harmonic disturbance, and that it is best if guys avoid that RPM, shoot right through it or shift before it, but make all efforts from doing anything that holds the engine at that precise RPM. Food for thought. He also said that racing and hot street engines, have shown that the factory torque specs for various parts is not near tight enough, case in point the harmonic balancer instead of being factory spec'd at 120 ft/lbs torque, should be 150! Flywheel botls are another he mentioned......he recently had another guy lose his harmonic balancer, just fell off! So, Dave Rebello at Rebello Racing woud be a good call for anyone doing a lot of high RPM stuff.
