    Well, the Engine rebuild book arrived today. My wife opened the package, “she yells from he door....we got a “Nissan Datsun Engine Rebuild book”. Me: cough cough...okay great. She’s smart she knows somethings in the hopper. Sent from my iPhone using Tapatalk

    Well, I told her this is better than gambling, drinking to excess and all sorts of unhealthy things men do. ;). I need an outlet and turning wrenches is one way. I’ll get a text when I am work in two weeks, it will be pic of the engine in the garage and she’ll say..”what is this”. Sent from my iPhone using Tapatalk

    It’s a P79. It looks pretty clean. I pulled the dip stick, it was already drained but looked clean. I didn’t see any major leaks or rust around the block of this engine. The fact that he’ll delivery it and it’s 15 miles from my house make this the winner. He’s giving me a 60 day money back guarantee that it will run without any major mechanical problems.

    So here are two more I found. First 1982’ had 148k miles when pulled. Runs. $490 delivered to my house. Second has 202k miles and N47 head. Says “rebuildable”. Sent from my iPhone using Tapatalk

    First stop. Place had the wrong engine data. Looks like a 260z engine to me. Sent from my iPhone using Tapatalk

    It has new plugs. I did a valve adjustment but may not have not done it that well. It was like 22 deg outside when I did it. My biggest concern is the white exhaust smoke. With the freeze plugs rusted out, not sure what type of internal rust is in there. I also believe there are some vacuum leaks. The idle adjustment really has no effect other than making it idle worse. Sent from my iPhone using Tapatalk

    Here’s a video I took two days ago of my Z running at my parents barn.. You can see she’s running rough. Haven’t been able to smooth it out. Low idle, sputters, and some clickety-clack etc... Sent from my iPhone using Tapatalk

    Great comments guys. This place is a great resource and I appreciate all the comments. I’m going to look at two of the engines today. I’ll take pics and post them because I know someone on this forum will see something I miss. I’ll also swing by harbor freight and see about the borescope. Gonna need an engine stand too. I’ll see the last engine one in about 10 days and make the choice then. In the meantime I’ll start reading the engine rebuild book I bought on Amazon. Can’t wait the see my wife’s eyes when she finds an engine in our tiny and already stuffed garage. Sent from my iPhone using Tapatalk

    Cliff, my N47 has a spray bar only I believe. I didn’t see holes in the cam lobes for oil purposes. Good idea on the notebook. So, I’m going with the general consensus that the 82’ NA is the way to go. I think it has a P79 not the P90 the P90 was in the turbo engine. I’m surprised no one voted for the N42 head engine in the 76’. Good advice on making sure it turns by hand and getting a Bluetooth borescope. Buying the rebuild book tonight on Amazon. Wayne, yes that’s pulled. I’m going to look at two of the engines tomorrow, the third is 2 hrs away (near where we went last time) and will have to wait a week or so. The plan is to bring it to my house and start tearing it down here and drive my wife nuts. I’m hoping it will fit in then back of my 4Runner on a pallet. I need to think this part through as it probably weighs in excess of 450#s. May need to borrow a truck or a small trailer...may need your help! Good thing I just had shoulder surgery 2 weeks ago! Supposed the be on light duty for 4-6 weeks. I imagine my doctor would be opposed to me trying to lift engines alone. Sent from my iPhone using Tapatalk

    Cool, didn’t know that. So my N47 head in that 82’ block could yield higher CR than the P79 head. This begs the question, when you do stuff like this are you changing the way the engine runs. I’m not looking to drive an engine that runs like crap. I see this happen with guys who build muscle car engines and put cams etc on them. Sure they’re powerful but also run and idle like crap. I want a smooth engine. Sent from my iPhone using Tapatalk

    Okay, I think the turbo is a no go. I don’t need more trouble and this will be my first engine rebuild. So help with the heads, pistons and compression for a strong street car. P90 Head was for turbos. Came with dished pistons and lower Compression Ration to accommodate for the boost. P79 was the NA turbo ZX engine with flat top pistons. This will yield a higher compression ration. ZH...copy all on my N47 in my car now an be used. There are 3 non-turbos at different places in my area. One is an 1980 and others are 82’s. Two of the places want a core charge....one $100 the other $200. That’s silly. I agree...look for the cleanest engine that seems less abused and with least miles and least rust and old leaks. P79 is the Head I want corrrect? This way I may not have to buy replacement flat top pistons as I would if I went with the P90 Head engine. Unless someone swapped them before which we’ll assume for this discussion....didn’t happen.

    ZedHead....here’s my takeaways from your post. Turbo mean lots of tuning work and extra stuff to do. Are you saying the NA engine isn’t flat top pistons? I thought hey were and dished on the Turbo. I don’t think I want all that extra work but it sounds like megasquirt is the way to go either way. So It’s not a good idea to use my current EFI stuff on the 82’ engine? Are you voting for the 82’ non-turbo. After reading all this I’m seeing that the turbo might be the wrong direction. My Goal...reliable, strong engine that is low maint and fun to drive. A little power is just fun to have Sent from my iPhone using Tapatalk

    That’s 3 votes for the 82’ non-turbo so far! Sent from my iPhone using Tapatalk

    Thanks Cliff. I drove a turbo once in like 1989. It was a peppy little car and fun to drive. I know there was like 1 turbo for every non-turbo built so they’re harder to find for sure. I forgot about a new ECU and probably AFM and wire harness. Maybe the guy would throw those in....probably not? I’ll wait for ZedHead to chime in. He always has good comments. Starting to think a 240 not rusted out is becoming like a unicorn these days. Sent from my iPhone using Tapatalk
