2many, you are an encyclopedia of knowledge!! Thank you for the additional info.

2many, on the 3.90 R-180: 720 4x4 1/83-6/83 is that the front or rear diff, or are they the same? A follow-up question is that diff a drop-in swap or do you know if there is other work/parts required?

:surprised Oh crap! I thought that all R180s were the same except for the gears. :cross-eye 2many pointed me, and others, in the direction of where to get different geared R180s in this post: http://www.classiczcars.com/forums/showthread.php?s=&threadid=1568 According to his info a 3.9 R180 was available in the 720 4x4 1/83-6/83. Since the 720 is also a Datsun will it be a drop-in? Where did yours come from?

You're welcome. I am always glad to help when I can. I have opted not to go for an R200 at this time due to the amount of work and extra expenses involved in the swap. I'd rather find an R180 with a 3.9 gear since this would be a drop-in swap.

Well now I can't find the post where I saw this item at, it was a guy in FL selling it and a few other parts. But I did find this guy in OH selling the same item for $50 + shipping: http://www.hybridz.org/phpBB2/viewtopic.php?t=21162 Ok, I kept searching but still could not find it but did come across another one for $60 and it is in CA. http://www.zcar.com/classifieds/index.php?method=showdetails&list=advertisement&rollid=772&fromfromlist=classifiedscategory&fromfrommethod=showhtmllist&fromfromid=34&

Looks like a W to me. These also look to be very clean!

Anyone..............anyone.............??? Please see prior post for my questions.

I forgot to get back to you on this one. I just wanted to say hey thanx guys! 10mm 1.5 thread was perfect, the engine is on the stand ready for me to start learning how to tear it down and build it back up. It's a little scary but I'm really looking forward to the experience! :nervous:

I have just pulled everything off this site (html, all links, all images, etc). The html has to be cleaned up a bit as there are references to Geocities still which cause the little popup to still appear but at least the info will not be lost now. I will clean up the html and ditch all the references to Geocities. If you would like this I can zip it and provide it to you (unzipped it is a whopping 1.3x meg); but you will have to contact me as I may not keep up with this post.

I think it can be purchased from either MSA or VB (maybe both, I just can't remember).

Welcome to the club. I too have been shopping for a 240Z for a few months now and am just curious where you got your's from? It may be someone I talked to at some point.

How much should one expect to pay for a P90 head?

THANX! Now it is very clear as to what the letters stand for! :classic:

I have seen people talking about L28, L28E, and L28ET engines. What's the difference? Oh yes, then there's the LD28 and the L28. Again, what's the difference?

So are the 5 way adjustable Tokico Illumina Shocks & Springs a good way to go or should I hold out for the McPherson coilovers? If yes, then is $564 (including shipping) a good price for all four corners? Car use will be some street driving and autox if this helps answer my questions.

I have been to these sites and would like to know where a '76 5 speed fits in; is it the same as the '77-'79 or is it different? Could not find it on these sites...

So then are the adjustable Tokiko Illumina actually coilovers? What is on the 240Z stock then? I thought that the typical setup for cars was to have the strut in the center of the spring. Is this not the case?

Holly cow that's ugly!! :sick:

Can someone explain what Tokico Illumina Shocks & Springs are and Coilovers? I keep hearing about both and do not know which is better or even what the difference is. Still trying to learn about the Z's.....

Ok, it sounds like there may be some confusion and misinformation here. To summarize will someone please tell us in which car(s) an R180 3.9 can be located? As well as where an R180 3.7 can be found?

He replied to me stating that he would be adding the VIN to the auction soon...and he did. Here's a quote from his update on the auction: "THIS IS A 1971 240 Z, NOT A 1970. THE VIN# IS: HLS3023407. THANK YOU FOR ALL YOUR EMAILS, PHONE CALLS AND QUESTIONS....ALL ORIGINAL BOOKS ARE INCLUDED...."

Is $100 (including shipping) for an R200 3.9 a good price? How hard are they to install in a 240Z and what else will I need to do so? OH! Also, is there a way to tell what the ratio is without opening the unit?

I just emailed him asking for the VIN. We'll see if I get it.

Currently I have the F54 block (flat-top pistons) with a P79 head on it (was pulled from a running '82 280Z). So either way I would have to buy the new head, which ever turns out to be the best. What's the difference between the N42 and the P90? They both are from the 280 so the sizes should be the same (right?) and they both have square exaust ports. I have read that the P90 is supposed to flow better yet the N42 does show to give higher compression with no mods. Now the N42 has bronze valve seats which I have read make this head expensive to rebuild and as I recall require you to run a lead additive in your fuel. I have also read that you should use the N42 and N47 only with dished pistons and the E31, early E88, P79, P90, and P90a with flat-top pistons. What about this information? Then there is the E88 head which shows to have the same compression as the N42 on an F54 block. So why not this one? I'm really quite new to all this and am trying to learn as much as I can but there is just SO much to know! So please forgive my lack of knowledge and numerous questions.

Ok, I have another thread going on compression ratios for the P90 here: http://www.classiczcars.com/forums/showthread.php?s=&threadid=7109 I have read that more than about 10:1 is not drivable on the street and I want to keep mine streetable. So...what is my best bet? I've read all the information on this and other sites and taking everything into consideration it seems as though the P90 head is my best bet (I will be using an F54 block) but the compression ratio is around 8.5:1. Is this good enough or should I try for something in the 9's? If I should try for a higher ratio then how? Car use: I plan on autox and occasionally driving to work just to enjoy it and keep things moving properly...NOT my daily driver, just a fun car that would be used for autox. Cost: CHEAP! I have to keep my expenses down and have remedial mechanical skills so any shaving etc would require to part going to a machine shop (I could probably remove and reinstall it but maybe not much more).
