xonix_digital Posted March 6, 2010 Report Share Posted March 6, 2010 Hey guys, I have been waiting a long time for this post. After scouring the Internet for almost a year, considering shipping from CA, AZ and beyond. I have finally found "The One" in my own back yard (Boston/Quincy, MA). For the record I have been on Craigslist every single day searching in a 250 mile radius for the perfect S30. At 7:00pm on March 5th 2010 I bought her. My 1973 Datsun 240z More pics to come. What a day. -=XD=- Quote Link to comment

shancerlelby Posted March 6, 2010 Report Share Posted March 6, 2010 rad! what are the plans for the old girl? Quote Link to comment
xonix_digital Posted March 6, 2010 Author Report Share Posted March 6, 2010 I am so stoked right now. First mini photoshoot with my first Z. http://picasaweb.google.com/alex.straffin/Z# First things first there are a bunch of places where I need to primer over some bare metal. That is my first priority. Once she's sealed up I'm going to fix the rear hatch gas shock attachment. Right now it's acting as a prop. Then I'll probably clean her out and vaccum the carpet and see where to go next. I got a new carpet kit and a new clutch with it eventhough the clutch in there is fine. I have lots of research to do and lots and lots of Dat-Rat fun ahead of me. I will be documenting the entire process here. -=XD=- Quote Link to comment
xonix_digital Posted March 8, 2010 Author Report Share Posted March 8, 2010 motor specs plz :P As far as I know it is just a straight up L24 with Triple Weber carbs, and a stainless steel header/exhaust combo. The carbs need to be tuned still but she runs nice. A little dip in power if you mash the gas, but I assume that a proper carb config would resolve that. I'm super interested in figuring all this out tho. Quote Link to comment
xonix_digital Posted March 18, 2011 Author Report Share Posted March 18, 2011 Hey guys, Back from the dead over here! I have made lots of progress since I last posted a year ago. I have been posting up with my progress via my build blog: Dirty S30 http://DirtyS30.blogspot.com But I <3 Ratsun so I will start keeping this build thread up to date as well. Here are some pics showing some of the highlights of what shes been up to. New House for me and my Z! Setting up shop. On Stands Teardown begins Man pulling up all that sound deadener sucked. Chemical Stripper Drop it like it's hot Pulling the stock L24 HIYAH!!! Much more to come. Quote Link to comment
xonix_digital Posted March 24, 2011 Author Report Share Posted March 24, 2011 A while back I picked up an L28 to swap in. Got it removed from the 4 speed tranny and mounted to the stand. And stripped it down to the block. To my surprise, the N47 cylinder head turned out to be from an 84 Maxima. The "MN47" as the Internet has named it. You can tell that it is from a Maxima because of the heart shaped combustion chambers. On a Z car N47 they are dished round chambers. this results in a bump in compression and if you are running flat pistons you get a quench or "squish" effect. I will be running the stock L28 dished pistons since I'm not extremely interested in a 10+ compression ratio and the detonation issues that could arise from that so i'll just run it in the mid 9's for comp and see how she does. Also on the rebuilding table are my triple Weber DCOE40s. The throttle linkage is going to have to be straightened out as the previous owner had bent it to get it to "work" lol. Quote Link to comment
xonix_digital Posted March 24, 2011 Author Report Share Posted March 24, 2011 Later, I chemically stripped the outside of the entire vehicle. Cleaned up the Engine bay rough spots and removed all of the hardlines. I used a mechanical stripper (paint remover) for this and do not recommend it. I will use a combination of chemicals and sand blasting from now on. And started stripping the other body panels. (a little dinged and dented I know) I will have a little "hammering out" to do. And then I had the bright idea to disassemble the doors so I can paint them inside and out and make sure nothing gets missed. What a nightmare. I will probably not be doing the other door this way since it was such a pain in the ass and i don't know how i'm going to get this whole thing back together. lol This is the engine bay after a quick blasting with my portable sand blaster. Gas cap area blasted. Chemically stripped and sand blasted the wheel wells. Up next, the beginning of under sealing with Zero Rust. Quote Link to comment
patra_is_here Posted March 24, 2011 Report Share Posted March 24, 2011 wow extensive work! Quote Link to comment
dat77sun Posted March 24, 2011 Report Share Posted March 24, 2011 wow cant wait to see more, you just gonnna restore her? what you gonna do for paint? Quote Link to comment
jeffball610 Posted March 24, 2011 Report Share Posted March 24, 2011 What kind of "chemical" stripper are you using? Seems pretty effective. Quote Link to comment
Skib Posted March 24, 2011 Report Share Posted March 24, 2011 nice score on the maxima head :cool: that motors going to run very nicely with that and the triples :D Quote Link to comment
blue72 Posted March 25, 2011 Report Share Posted March 25, 2011 Wow, nice solid base to start from. It looks even more rust free than my Z which spent it's entire life in Arizona. I know what you mean about the doors too, I had to leave one assembled so that I could figure out how the other one went back together. I'll be sure to check for updates on this build.

xonix_digital Posted March 25, 2011 Author Report Share Posted March 25, 2011 wow cant wait to see more, you just gonnna restore her? what you gonna do for paint? My plans include a 2.8 swap and suspension modifications for the most part. Everything else is going to be pretty stock. As for the Color I have chosen KV3 which shipped on Gen 5 Maximas as "Grey Lustre" and is currently manufactured by PPG as Charcoal Metallic and by BASF as Green Grey Metallic. They both look the same to me in the books, but when compared to the originally shipped color they are significantly different. Not terribly concerned with that though. What kind of "chemical" stripper are you using? Seems pretty effective. I use Jasco Paint and epoxy remover. by far the best consumer available stripper I have ever used. Works like magic. Before: Application: After 10 minutes: Wipes right off with a paint scraper: nice score on the maxima head :cool: that motors going to run very nicely with that and the triples :D I very much hope you are correct! my setup caused a bit of a huff over at HybridZ haha. We'll see how it goes. :lol: Quote Link to comment
turboHLS30 Posted March 25, 2011 Report Share Posted March 25, 2011 That is crazy. Do you like the outcome? Quote Link to comment
xonix_digital Posted March 25, 2011 Author Report Share Posted March 25, 2011 That is crazy. Do you like the outcome? From the chemical stripper? Yeah I think it's a great product. I have to treat the metal afterward with Picklex20 so it doesn't rust while waiting for paint. That's why it looks all chalky in some of the pics. It chemically deactivates the rust and turns it dark grey and white. Quote Link to comment
hellamikey Posted March 25, 2011 Report Share Posted March 25, 2011 I very much hope you are correct! my setup caused a bit of a huff over at HybridZ haha. We'll see how it goes. :lol: Everything causes a huff over there. lots of guys with pathological needs to feel better than everyone else. "Doughebags" is the technical term. Let me guess, they gave you a finger wagging 8 page lecture on squish zones and closed chambered heads/issues with dished pistons? Fuck it, run what you want to run. keep an eye on it, and if it detonates, swap heads to an open chamber. BTW nice job so far man! Can't wait to see it finished. Quote Link to comment
INDY510 Posted March 25, 2011 Report Share Posted March 25, 2011 . Wow!!!!! ..... that's alot of work!!!! . .. . . . this thing is gonna be awesome ........... .. :thumbup: Quote Link to comment

I mean I bought the motor complete for $200. Lol Im just not on that level with it I guess. Id rather blow it to smithereens while learning why, than have some guy calling me ignorant for not caring.

KELMO Posted March 26, 2011 Report Share Posted March 26, 2011 Great, now I REALLY want a Z...and the coupe ain't even done yet :P This has the beginnings of an awesome build, gonna be watchin this one. Also glad to see I am not the only one posting up pics with my favorite adult beverage in them :lol: Quote Link to comment
xonix_digital Posted March 28, 2011 Author Report Share Posted March 28, 2011 Hey guys, I got to spray the newly stripped wheel wells and inner body. Here is my paint setup. Cheapy Harbor Freight HVLP gun works great for spraying sealers and primers. This is my ridiculously tall spray contraption. It consists of the HVLP gun, a pressure regulator, and a water filter. Mixed the paint with 1 part Lacquer thinner to 4 parts Zero rust to thin it out enough to spray. Spray away! Cowl Under Fenders Rear wheel wells Pass wheel well I am very happy with the results. Zero rust is a waterproof sealer primer that seals out air and water making it chemically impossible to rust. But I'm sure my Datsun will find a way around that.... lol :lol: Quote Link to comment
