  1. Wow DF, I would have never guessed that you would sell your coupe! You've put so much time and effort (time X effort = money) into that beast. Definitely one of my favorite coupes of all time. GLWS!!
  2. Thanks DF. At this point i think I will take the easy route and buy HID bulbs.
  3. Ok. So I did understand. Thanks!
  4. I wasn't thinking of gettig LEDs, but HIDs. Like you mentioned, you've got to fork over good money to get a good LED unit. Supposedly, these Hella lamps have the hockey stick cut off for the incoming traffic on the left side. Here's the description from the website: PRODUCT DESCRIPTION Hella 7" Round H4 Conversion Headlamps Datsun 240Z 260Z 280Z S30 280ZX S130 Roadster 311 70476 99996-70476 Made in Germany Includes 60W/55W H4 Hella bulbs These lamps are designed for cars that live in and/or travel in countries that drive on the right hand side of the road. They emit the “hockey stick” lighting pattern where there is a sharp cutoff on the left hand side that keeps the light from glaring into on coming tracffic Also, these lamps have just a slight curvature on the glass face- not totally flat, but not a noticeable outward bulge like the OE sealed beam types." So, my question to clarify things for me, will I be ok if I buy some HID bulbs? I won't have to upgrade to a relay system to avoid melting anything? At the same time I'll have better lighting for night driving? Or just run with what I've got and use the relay system? Information overload ?.
  5. Very good point DF!
  6. Very good point DF! Thanks to all of you for your tips and sharing your knowledge. More light and less current draw... It sounds like it's a no brainer to run with HID or LED instead of what the kit came with.
  7. I figured since the new bulbs I have are 60/55W and stock being 55w,I could get away with plugging these bulbs in without issues.
  8. I will do exactly this. I appreciate the tip. I remember seeing these harnesses with relays and plugs on Amazon about a year ago when I was considering using H4's.
  9. Thank you. Good looking out! I vaguely remember reading about the power going through the switch but I had totally forgotten about that detail. Last thing I want to do it ruin perfectly good components or worst, burning down the car.
  10. The lights came with 60/55w bulbs, stock units were 50/40w, according to the owner's manual. I can see if the connector and wires get hot and go from there. If it's getting too hot, then I can either upgrade the wiring or change to a fluorescent bulb.
  11. You're right, Mike. I don't want to spend much money nor get too complicated with modifications. With the new pump and bearings I should be ok as far as oil pressure and flow. I got the oil pump and some head lights that I was told was offered by Nissan Motor Sports for the 240z and Roadsters. I didn't want to spend too much on LED headlights so I thought these Hella H4's would be a good upgrade. They're supposed to be a straight swap. but we'll see.
  12. I bought a new OEM pump for $60 on Ebay. I always crank the engine until I have some oil pressure as you've suggested ;). Hope there are not any other issues or surprises with this engine. Thank you guys for your comments and advice. I'll keep posting as it happens.
  13. I'll get emery cloth and clean the journals. The engine sat in the car since the early 2000's, I believe. Also, going to hone the cylinders. I don't want to spend any more money than I have to on this engine for a bore and larger pistons. I have too many projects and can't afford to spend too much on an engine like this one. I'm already at about 300 on seals, bearings, rings, gaskets and such. That doesn't including what I will pay for the motor itself and the machine shop work on the head. Would you guys buy a new oil pump or just run the original?
  14. So I started to take the engine apart and see what I'm dealing with internally. Unfortunately since the engine didn't get the oil changes it needed, I will rebuild it for peace of mind. Made sure the head had the oval intake ports. Also, the mystery of the bent push rod was solved. Looks like a valve seat came loose. I'll have to take it in and get all the valve seat squared away with the machine shop. While the head is there, I'll have them clean and resurface the head and check valve leak by. You can see above on piston #4 where the it made contact with the intake valve. Cylinder #3. It could be moisture from the engine just sitting there but the head gasket could have been bad, too. Who knows and who cares.
