EFI 304 into HZ?

[levymetal]

just a quick question, will a holden efi 304 fit into a HZ wagon? easily anyway... car already has an 8, unsure of the size but it's whatever it came out with. weak as **** and dying. My mate wants to get rid of his hz wagon, $1500, straight body... only needs a good paint job to look awesome so i'm thinking about doing it up.

will go in no probs. no engineers cert needed because they came out with a 308.
you will need to sort the electrics out. i have a mate who has been looking into putting one in his hq tunna and a auto sparky told him its a simple wireing job.

Best way to do it is to buy a stacked Vn 5ltr or somthing.
Transfer it all in, itll need the Vn wiring loom too and all that, bit pretty sure most things will bolt straight up.

The motor itself is pretty much a bolt in job. Just done the exact same conversion in a WB ute.....any more questions just ask. Happy to help.

Seen as though you just done the conversion did you wire it up or get a sparky to do it..If you done it yourself any help would be appreciated.. I'm starting mine Saturday..

I used a Castle Auto Electrics wiring loom/patch harness.

Well Unlike you I dont look at dogs balls so I dont know and if there is a rule why is it an option.. Im not selling anything or promoting so where is the problem.. Seems your the only one with the problem.. Build a bridge and get over it..


There is a rule against what you said cause it has been edited..

Been there on this one assisting (I did the wiring - using VP and VR wiring diagrams ) a mate with a VS V8 and auto. into an HX. It was a few years ago, so this is what I can remember.

The engine is a straight bolt in (as you might expect).

The 4L60(E) trans. will require a new cross member/mount. I think that was bought from Castlemaine Rod Shop. The driveshaft will need to be shortened.

The speedo needs to be sorted. With a VN/VP the speed signal needs to go through the VN/VP speedo head to work. With the VS there was two speed sensors one went to the PCM and the other was substituted for with a speedo gear and cable (also from CRS?). I think that VR are similar.

The driveline we used had already had the anti-theft function removed. That would be trivial on a VP or VN Calais system.

An engineer's report is going to be required (even if you kept the HZ trans. and the bolt pattern may not match the later EFI blocks - I don't think that it does) because wiring changes are required.

Here: National Code of Practice for Light Vehicle Construction and Modification (NCOP)

A surge tank and EFI fuel pump and return line will be required. A conversion to straight LPG might be a way around and you would get back the $2K.

A carbon canister will be required (not with LPG).

A brake upgrade may be necessary depending on the engineer and perhaps the engine used.

Bloke at work converted his old ute to vp engine and box, i consulted him on all the wiring mods, it was a simple mod of the old vp loom he had. One thing i do remember is you need to bridge out the old security bit on the computer, i think it was the pink wire that goes through the passenger side secuity key barrel . All you need to do is hook the computer input to the acc.
You doing the trans too, it would be a shame to bolt the motor to the cappy tri-matic.

Cant be done unless you use an adaptor plate anyway.....EFI 304's are turbo pattern blocks.

You wouldn't waist your money on an adaptor plate for a Trimatic anyway, just go with the T700 or go with the T350 if you only want 3 gears!
