Hi guys, we have just bought a 92 Feroza, and I have a 3.8 litre V6 with the computer and loom. Has anyone heard of this conversion? I am very tempted.

They are a great little truck, but the little Corolla motors were never known for their power.

It's not a Corolla motor, it's a HD Applause motor.

Petrol powered Rocky's had the Toyota 3Y engine in them though.

No idea about the conversion, or if the engine will even fit. But it sounds potentially very dangerous - you're putting in more than twice the power, and the brakes already struggle...

If you ever get a reply re 3.8 Holden conversion, please let me know.

I have a Feroza and plenty of time.

I have a '91 and '93 Rocky (F300 petrol EFI) as well as a '92 Feroza (F300 petrol EFI). All 3 with manual gearboxes. The Feroza has an oil cooler and a larger capacity radiator, and the 2 Rockies have air conditioning, with a smaller engine cooling radiator, but with an additional (small) air con. radiator. Aside from these differences, over my 12 years and continuing ownership, I haven't noticed any differences in the engines.

I was of the opinion they were both same, modified Daihatsu Applause motors with a cam suited to lower rev torque. Fantastic little 4x4 vehicles... wish they still made them, 'cause I'd buy a new one.

Don't suppose anything ever came of this. I'm currently running a supercharged factory HD-E 1.6 (with a rebuild and a few mods), but considering doing a Commodore 3.8 V6 swap

FYI. Your '91, '92 and '93 F300s are all Ferozas. In some countries they were badged as Rockys. F300s and F310s (the wide track variant) are all 1.6L with the same HD engine. Whether it's badged as a Feroza or a Rocky, it's still the same vehicle.
