bear351c 10,270 Posted March 10, 2014 So the engine swap form includes an option for going from 6 to 8? What was different on a ZK from 6 to 8 in regards to suspension and brakes? It already has discs at the rear. Yep, sure does. As they came out the factory with them, its just a piece of paperwork, and bingo! regoed as a V8.

SLO247 1,713 Posted March 10, 2014 Higher rate fronts? Have you done this Dave? Share this post Link to post Share on other sites
bear351c 10,270 Posted March 11, 2014 Yeah, thicker spring rod. I think it's 18mm dia, and 6 cyl is 16mm. Not sure, but, just go the local parts shop and buy Kings or Pedders. Used to sell King Springs, and they are 15% firmer than standard, out the box. Just get the height you want. Low/Superlow/ STD etc... Brake rotors are same for all. Shocks are your choice. Although if you get low, low springs, get shorter shocks. Done this twice. The rest is fuel line, engine mounts, wiring etc. Share this post Link to post Share on other sites
SLO247 1,713 Posted March 11, 2014 Well thats easy. I've already changed the springs and shocks. I was given a set of mount plates years ago too. Thanks Dave. 1 bear351c reacted to this Share this post Link to post Share on other sites
ronny 204 Posted March 12, 2014 go in to Rego and fill out an engine swap form. Just paperwork. Id be interested if that was the case I tried that first and was told no, engine capacity change was a regency job Unless you know someone there? Share this post Link to post Share on other sites
bear351c 10,270 Posted March 12, 2014 Yeah, Ronny. As I said, done it twice. Just be patient and don't try to do all the changes at once. Changed my XB ute from 200 to 351, and an XD 250Xflow to 351. No Regency. Vehicle details MUST match what Rego has on file, or no good. Original engine/chassis number/rego plate..... Share this post Link to post Share on other sites

Ok, so just scrub off the new v8 engine number and put the old 6cyl number on the v8? Share this post Link to post Share on other sites
SLO247 1,713 Posted March 12, 2014 Dave, you mean rego it with all the numbers matching then change it later right? Or did I miss some sarcasm. Share this post Link to post Share on other sites
bear351c 10,270 Posted March 12, 2014 Original engine in car, on trailer. Get country cops to verify its existence, then stuff in mighty 351, and do engine swap paperwork. Share this post Link to post Share on other sites
SZKsa347 6 Posted March 21, 2014 Cant legally put a carbed v8 into a xf/zl. However you can go an efi engine. Cant go backwards - so to speak. Ring DTEI for more info. Been there done that with my ZK Share this post Link to post Share on other sites
