Hi all, what i would like to know is if anyone knows anything about putting a Holden 5 litre EFI V8 into a 75 series Cruiser. I know i can get the conversion kits and all the that, just wanna know what other mods need to be done. Also as its a 1HZ will the tanks need to be changed?

Really wanna keep air con and power steering. I mainly wanna know about the mods that are needed and how much an engineers report costs.

Now before everyone says go Diesel or Turbo it, NO! So Dont say it.

I want a EFI 5 Litre 304 Holden, its only going to be a Hunting/Bush Bashing rig, that will have minor mods but running 35'' Tyres and about 4'' suspension lift and 2'' body lift.

Anyone have any thoughts/opinions or first hand knowledge?

Kroozer, I think you may find that with a 6" lift and 35" tyres, the motor will be the last thing for an engineer to worry about!

Don't think tanks are fuel specific.

you will need an efi tank from a fzj75, an adapter obviously, i wouldnt run the t700 box as it will die from the weight, why not go 5.7 if you are going to do an efi holden motor?? transfer gears to suit the v8 would also be worth the effort, lower revs at 100km/hr an 80 series gearbox if you want to keep 5 speed is worth thinking about too...they have better gear spacing and low range, plus stronger 5th gear for towing.

Dont know about the cruiser, but helped a mate do a GQ ute, same mod, and the big problems were, making the computer stop looking for the auto trans, kept running in limp mode, cos his efi 5 L was from an auto.
A surge tank with apropriate pump to feed efi fuel system.
Used old original deisel tank.
He used holden PS pump and nissan box, and holden AC pump and nissan rest.
Mate, it goes like a cut cat, good fun machine.
His 4500 80 series petrol is still his favourite.

Cheers Pesty

Hi Kroozer,
Brian from GPS Oz in Mona Vale, Sydney had an 80 Series wagon with a very similar conversion to what you are proposing.

It might be worth giving him a call.

The biggest differences would be the 80 series was a petrol auto with EFI to begin.

Fella down the road got his ute done in Gympie sounds good coming up the street. Could find out more if you want. All up cost was around the 20k mark. My dad has just put one in a Blowup Nissan. Lots of mods lots of money. Husband is trying to talk me into doing the same with the 80. Hes away and ive got it booked in Monday for a rebuild before he gets his way.
