AK-Z Posted June 14, 2005 Share Posted June 14, 2005 Has anyone tryed to fit a RB head to an L6 (24,26,28)? I know in japan that the z432and z432r versions had the S20 engine (DOHC engine that RBs were derived from), did the S20 engine use the same block as the SOHC? I recall that in like the early 80's there was a company that made race application DOHC heads for the L6 engine, has anyone happen to stumble apon one of these rear finds. I know some one on this forum is making one from 1 1/2 240sx (KA or SR heads, Idon't recall which) but I think thats way to much fabbing to be practical for me.

Jsquared Posted June 15, 2005 Share Posted June 15, 2005 he's making one from two KA24DE heads. I don't know about the R432 or the S30 (yet , sounds like I need to look up some stuff), but OS Giken did make a DOHC head for the L-series sixes and for the four-bangers as well... although I would imagine that getting your hands on one of those would be akin to me getting a date with Angelina Jolie Link to comment Share on other sites More sharing options...

AK-Z Posted July 3, 2005 Author Share Posted July 3, 2005 make sense now, but no one really has answered my question. can you fit a rb valve train on a datsun block, or has anyone tried? Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted July 3, 2005 Share Posted July 3, 2005 I laid my Tomei metal RB head gasket ontop of a F54 block I have, and its a NO GO..... way to many things don't line up for it to work. Now I can confirm, that the head bolt pattern / bores are in the same location on both blocks, making it abit easier to find a tourqe plate for honing....

Guest crshbndct Posted July 4, 2005 Share Posted July 4, 2005 so is it just oil and coolant chambers that dont match? becasue there are other types of rb that have very different heads (rb30e, rb20e etc) Link to comment Share on other sites More sharing options...
johnc Posted July 5, 2005 Share Posted July 5, 2005 Search, search, search. The DOHC, RB, Mercedes, KA, head swap discussion has been done before... Link to comment Share on other sites More sharing options...
