Tony D Posted May 26, 2004 Share Posted May 26, 2004 The "Goertz Paeco" was a serious search item. Albercht Goertz knows nothing on this head, and disavows anything to do with any developmental engine work for anything pertaining to the engine. Paeco, the race engine builder in Birmingham Alabama, also disavows any knowledge of this head, saying something along the lines of "We never casted no heads before, that one surrrrre looks purdy!" So both of those leads were dead ends. The only thing I know for sure was the seller at the Swap Meet bought the lump at an "estate sale" which means probably there was an engineer/draftsman living in Sandiego in the early 70's that had this built. Why the casting has "Goertz Paeco" on the rear is a mystery, and the buyer has gone back to find the swapmeet seller to no avail. The blueprints are hand drafted, inked, and in english measurements. Unfortunately, the prints have neither a draftsmans' name, or company of production. It amazes me to think someone sat at a table and literally started from a blank sheet and made this much happen! And yes, that's why the second group of photos was added, for the "question" that I will not dignify with a response. Something is to be said for actually reading the original post, and comprehending the words "unfinished". Contrary to popular belief, I now concede there is such a thing as a stupid question! As for "Looking at the design, it is very similar to the Toyota 7MGTE out of the Supra" The 7MGTE is a derivation of the "G" heads that came before it, and the 2000GT {1M-G}(as well as it's four cylinder cousin the 67 1600GT {2T-G}) share similar Yamaha-Inspired Design Cues. I have some photos of a 2000GT engine on a stand from the Toyota Museum in Carson, but don't have them available on this computer----alas! Otherwise one could be shot up for comparison. Yeah, I get into some interesting places, don't I? Quote Link to comment Share on other sites More sharing options...
Guest Lucidstrife Posted August 16, 2004 Share Posted August 16, 2004 If there are any other pictures of any of these heads that havent been posted already, could someone send them to me? my e-mail is Neostrife@hotmail.com Lucidstrife Quote Link to comment Share on other sites More sharing options...
Guest zline Posted October 1, 2004 Share Posted October 1, 2004 Russ Arao can make camshafts for the 6 cylinder KA24 head if you want call him up http://www.araoengineering.com Quote Link to comment Share on other sites More sharing options...

turbobluestreak Posted May 26, 2005 Author Share Posted May 26, 2005 Nope. I haven't worked on it in a long time. I have been concentrating my efforts on getting my z ready for this year. But a little off topic my custom intake is done and will get some pics up on here soon. tbs Quote Link to comment Share on other sites More sharing options...

BlackBeaut Posted June 4, 2005 Share Posted June 4, 2005 What's happened to the pics of this mystery head? or is that another mystery? Cheers, Rob Quote Link to comment Share on other sites More sharing options...
DAW Posted June 8, 2005 Share Posted June 8, 2005 Has anyone on this site ever compared head gaskets from L28/LD28 to Mercedes 2.8L dohc inline 6cyl. (vintage 1970's)? Similarities between Datsun and Mercedes inline engines are documented and archived and they are striking. I recently bought a Mercedes dohc inline 2.8 6 cyl. If it weren't for the front sump, I'd be working on putting it in a Zcar but I might have to settle on putting it in the Datsun 910 (diesel Maxima) when I pull that LD28/N42 hybrid gas engine to swap pans and put it in an early Zcar. I'd be tempted to put the 2.8 6cyl in my '82 230CE (Euro model), but it's a great car as-is, with the 2.3 4 cyl, euro cam and c.r., etc. I just need to swap-in a 2.88 for the 2.24 so it will shift into 4th gear below 80mph (it's geared for Autobahn at present, i.e., 120 mph).

Jsquared Posted June 9, 2005 Share Posted June 9, 2005 just a thought... the KA has a dual timing-chain setup so that the cam gears will fit (narrow head, small gears), how would this be worked out if the "KA" 6cyl head was finished for the L-series?

1 fast z Posted June 10, 2005 Share Posted June 10, 2005 Well here is the timing work that Mcadam And I have completed on our DOHC head! 1 Quote Link to comment Share on other sites More sharing options...
Jsquared Posted June 15, 2005 Share Posted June 15, 2005 holy crap! that is freaking sweet... when did you get the welding done? I'd be interesting in seeing how it was finally combined... and interested in seeing how much one would run Hahaha, I haven't even gotten my 240SX back together and I'm already getting price generalizations for an L28DET Quote Link to comment Share on other sites More sharing options...
Dnaught14 Posted September 14, 2005 Share Posted September 14, 2005 What is the current status of this project, I know that people were getting closer months ago and then the post dissapeared. I hope it hasnt died. Give us all and update! Quote Link to comment Share on other sites More sharing options...
AK-Z Posted September 14, 2005 Share Posted September 14, 2005 I would lile to know how you welded the internal channels and did you have a custom set of cams made for the modded 240sx head. Also was the head tempered after the welding was done. I wish that I had the patience and money to do the same thing. Quote Link to comment Share on other sites More sharing options...
Gollum Posted September 16, 2005 Share Posted September 16, 2005 That's pretty insane in it's own right. I'd love to see that motor running 1 fast Z. Quote Link to comment Share on other sites More sharing options...
Mack Posted September 26, 2005 Share Posted September 26, 2005 the head is not welded yet, and I am not sure if we are even going to weld it, or if we will just be using gaskets with press fit pins inbetween the halves (thirds, I guess) to keep them aligned. As far as the cams, valve train and timing..... well, you'd be surprised to learn how many stock or very slightly modified nissan parts are used in this head.... Unfortunately, I moved back to Minnesota this year, so work has been temporarily suspended on this project, but rest assured, I wil get back to phoenix to visit 1 fast Z some time very soon, during which, a marathon of mechanical engineering, modifiying and machining will take place and we will get this project DONE.
