Anyone done an engine conversion on their Rocky?

Unread post by waranger » September 10th, 2012, 1:48 pm

Guys/girls,

Have a 93 Rocky ute for a parts runner...

Motor is getting tired and burning a bit of oil..

Expensive to get a second hand (if you can find it) motor to slot in.

Surley heaps of people out there have done a conversion. Looks like plenty of room for a V6 commodore or 5L ford V8..

Any done a diesel upgrade/conversion???

Is your Rocky engine the same as the Toyota engines.
Being the same company, there may be a Toyota engine swap possible with minimal effort and perhaps an increase in capacity.

G'day mate,

Not sure what the toyota equivillent was? I agree though, there are lots of parts on it stamped with the toyota brand so surely there is a popular Toyota engine of that era that someone has previously done.

Do like the idea of a 5L V8 though! haha

Ive been running a v6 commodore motor for about five years now with no problems.Its hooked up to the daihatsu 5spd.
But you need the gearbox with the detachable bellhousing which luckily mine had.
Mine was a turbo diesel so the gear ratios are suited to the v6.Its all engineered and registed in nsw.

Hi guys,

Does anyone know if the gearbox from a F85 3Y petrol rocky can be easily used in a 1992 Diesel rocky ??
Not sure on the model code of the diesel, but I know it's 2.8iTD

Cheers.

If you want to do a conversion the most important part is having a gearbox with a detachable bellhousing.

This mob is were i got all my gear http://www.dellowconversions.com.au/
From them i got the bellhousing clutch and pressure plate and flywheel also got basic engine mounts of them too.
You will need to give them the flex plate/ring gear if your donor motor is an auto.
It will be easier if you have a ecotec motor from a vt onward as the throttle body is in the centre not at the rear which is were i had clearanc issues with the firewall and had to make an adapter.
The other thing you need to think about is the gearing the 3y run pretty low final drive where as the diesel has 3.36
also the diesel fuel tank has the return lines you will need for the EFI.
Mine runs 2x fuel pumps and a surge tank mounted 1/2 way down the chassis the low pressure pump to suplly the surge tank then a VL turbo pump from the surge tank to the motor.
I kept the factory aircond so i used the commodore engine mount on the left hand side and the dellow mount on the right
I cut the whole diahatsu mount of the l/h side and fabricated a new one and made an adaptor for the r/h side.
Also made some brackets to fit the commodore radiator and fan.
For engineering you will need an unleaded filler neck on the fuel tank which i got out of a late model feroza and bolts straight up.
Also made my own sump and oil pickup and power steer hose.
Then you need to think about wiring.
I can take some more photos if you like or if your in sydney you can come and have a look :)

Thanks for that mate is great help. Unfortunately im in adelaide so wont be able to come have a look. This i goin to be a bit of a project. My rocky has seen better days. So ive decided to tidy it up, get it back to what it should be, obviously minus the fact im going to put a different engine in. I will post photos as some point, of it as it atm and more as i slowly fix it up. They really are great little 4x4s and heaps of fun.
