  1. Have you downloaded the 280Z Factory Service Manual for your specific year? They're free and readily available on and Might fill in the gaps...
  2. Kia used the same blower in many different models and years. I have seen many with that hose to circulate air over the electric motor. You can modify your blower box to use it or block it off. Here's a picture of the Kia blower I installed in my 260Z (Goldie) all those years ago and a picture of a spare Kia blower that I have. I think most of the guys doing the swap lately have just bought them new from the dealer. Maybe Amazon... (edit: Yup, Amazon has them...)
  3. Try this: It will require a helper. Loosen the four hood bolts to snug - you don't want the hood to drop or move by itself but you want to be able to force movement. With the hood up and the bolts loosened - using both hands, one on the front edge of the hood and the other towards the back of the hood (one hand down, one hand up on the side of the hood each man (or woman)) - push the front of the hood back and the rear of the hood forward as much as it will go. So, down hand aft, upper hand forward. The bolts should have been loose enough that the bottom bolts will move as far as they can towards the rear of the car and the top bolts will move as far as they can towards the front of the car. You don't want them to move up or down, that would spoil your hood-to-cowl fitment. May help, but if it doesn't you'll have to repair, modify, or replace the hinge as suggested above. This is a simple and quick thing to try to get the nose of the hood down. It has worked for me on several of the Z's we've had in the shop. Some just had to much wear in the hinges to be able to get the hood to stay where it belonged. If the hood sits properly when the torsion rods are out and pushes up when the torsion rods are in place, the hinges are too worn. Please keep in mind that these cars were built in a different era and fitment back then was nothing like the sheet metal fitment of modern vehicles. When we were putting Z cars back together after paint we usually tried to get fitment that was as "visually pleasing" as possible, not perfect alignment of all the parts and seams... (The factory certainly did not take the time to shim and correct body panels for perfect alignment.)
  4. I have access to a 1971 (late 1970) and a 1972 at a shop near me. I have a 1973, my early 1974, and my son's 1976 at my house. I the next day or two I'll try to examine them for differences and get some measurements.
  5. They changed the pinion body clamp design in the ZX transmissions. The pinion is essentially the same but the mount is reversed 180 degrees. On the early transmissions, the key and bolt were on top. With the ZX, they moved the key and bolt to the bottom. It was actually a smart design change for ease of service but it has tricked many a Z owner. The change was only in the pinion body (carrier) - the gear & shaft remain the same and are interchangeable as are the seals. If you take one completely apart, you'll see what I mean. To use an early Z transmission pinion assembly in a ZX transmission, you'd need to cut a new slot on the bottom of the pinion body. Easier to either get the right assembly or swap the new gear & shaft (which you can order separately) into the correct body for the ZX transmission.
  6. Looks like they did on the rear cover. Can you get anything between the cover and the plate to cut the seal (slim putty knife)? Have you tried standing it up with the input shaft on a board (tail straight up) and tapping the front cover downward.
  7. Trying to put a Z pinion in a ZX transmission... You can swap the gear & shaft & seals to your original pinion body. When you have two cars in one, you have to remember which is which when buying parts. 😋
  8. I love that the OP has never posted back to his thread and yet it's taken a life of it's own...
  9. And you'll need to strengthen the frame considerably! 500 RWHP will twist a stock body to pieces.
  10. Yup, the foam gets old and crunchy - doesn't hold the metal plate well anymore.
  11. We've seen stock L28E 280Z's on the dyno running from in the 90's RWHP to 110 RWHP - depending on condition. (don't be dismayed, a Z doesn't need much to make it fun to drive...)
  12. You can buy new connectors and pins from You'll need a crimping tool and some patience but replacing those corroded spades will be much better than cleaning them. It's not hard to de-pin those connectors either...
  13. We actually have the correct engine block color. Years ago we took an unmolested part to one of our paint suppliers and had them match color and save the formula. I have the paint in single stage for brush-on (or HVLP) and they also make spray cans. We've painted blocks both ways and I find it easiest to brush-on the block and spray parts like pulleys, brackets, and idler parts. IDK if I'm ready to sell and ship block paint, but not painting a block in stock Datsun Blue is one of my OCD triggers...
