info on changing motor on HZ 1 tonner

Muse7707 · #1 11-04-2007, 09:17 PM

Hope someone can give me some advise on this one.

Am in the process of buying a, probably, HZ 1 tonner with the standard motor in it. What I need to know is, how difficult is it to change it over to a modern motor?? Most I've seen converted, and there's not that many, have a VN to VP motor in them.

Is this expensive/hard to do??

Any particular reason why it's commonly the VN/VP motor??

Does the entire drive line need to be changed or modified??

Do I need to get an Engineer's Certificate (VAS) to have the engine changed over??

Any help would be appreciated.

Thanks.

To stick a v6 into an hz you can get a conversion kit from Castlemain Rod Shop. You can use the v6 and t700 with a modified tailshaft and the stock diff. V6's are a good cheap conversion, takes a bit to set up but the motors are cheap. Yes it will need an engineers cert from whatever state your in.

Theres that much room under the bonnet of a z you can pretty much stick you can think of anything in there.

good luck with it mate.

Thanks for that.

I'll post pics of finished project. May still go with overhauling the V8 in it though. Don't want to take on more than I can handle.

Or try V6 Conversions http://www.v6conversions.com.au/hqtowb.htm They seem to do quite a few.

Meh, what's wrong with the old motors mate? Is it a 253, 308 or a 202 straight six?

If it's an eight, I'd just keep the current engine.

Also, I'm a huge fan of HZ's (one tonners and statesmans particularaly) and so I def wanna see it!

i thought the tonners only came with a bent 8, thats why i think someone swapped the motor in the bothers hq tonner for a 202, a standard vn v6 has more power than the old 308's anyway unless its been worked so i think its a good conversion
