Hey y'all, I need some clarification. From what I've read in various forums and conversations & a few google searches. Datsun utilized 2 or 3 versions of the 5 speed for the 280z. Again, from what I've read. It seems as though the later 80-83 version is the more desirable due to it being a close ratio gearbox compared to the earlier versions. And from what I can tell, it doesn't seem as though there is any identification numbers stamped on the transmission. I did read that if the 5 speed has one hanger at the tail end then it's the more desirable version compared to the earlier version which would have two hangers/forks? There was a 4204C label stamped on it, not that this probably helps. If anyone can tell me which version of the 5 Speed I bought, I'd appreciate it. Did anything that I mentioned above seem to be completely wrong? Thank you in advance!
Hi, I am planning to build a race car engine for my 280zx endurance Chumpcar racer. It's all amateur hobby racing and nothing professional, still it would suck very much if it breaks during a race. I am doing this 50% for power and 50% for reliability. I am a beginner hobby mechanic. I got all the OHC Nissan books My goals: - 100% for 10hours without blowing up several times a year. - Usable range 3500 - 7000 RPM (To keep cost down and keep some reliability) - 200HP crank (but 250 would be fantastic) Engine will consist of the following: - Megasquirt fuel only (can't do timing due to race regulations) - Race camshaft (Schneider 284-92F is a good candidate, 284/292 (236/244 @ 0.05"). 488/.504 lift) - MSA Headers - F54 block - N47 head (worth spending $650 for a Lonewolf porting?) - Some exhaust (2"?) I have a F54 block that comes with pistons but no head. This is what I plan to do: 1. Replace piston rings 2. Replace main and rod bearings 3. Replace all gaskets 4. New waterpump 5. New oilpump 6. New cam springs 7. New rocker arms 8. Should I get new pistons (block comes with pistons)? 9. Should I get a new Timing kit? Is there anything I should add to my todo list? Does the cam make sense? Is there something that is specially hard that I should leave to a professional? First time I ever mess with engine internals. I am not super tight on budget but forged pistons is way out of my budget. Many thanks
