how do I power up a VK motor

[Bjork]

I have a 3.3 carbureted vk motor and 5 spd box in an hz one tonne ute, I am wanting to as economically as possible power this motor up to handle towing a double horse float. I am looking at going the way of an rb30e turbo, is this the way to go, if so is it involved? Any suggestions would be greatly appreciated.

Put a 308 in it.

If you put any more power than stock through a 6cyl VK 5spd box it break. just letting you know.

I don't think the rb30 is really what you want for towing. You want low down torque for towing. Your best bet really is a v8. Even a 253 would be alright. What ever you do though you'll be wanting a stronger box. If you stick with the six, throw in a cam with a torque and economy grind, extractors, maybe some head work, an intake manifold with long runners, the vk injection manifold is good.

super charge the 6 ....

HZ 1 tonner from memory you could put a 350chev in it legally under polution regs, 5 speed with a 3.08 diff or 4 speed with a 2.78 it would be quite economical with the right cam, or a hoden 304/308 again same gearing with the correct cam would be your best bet.

really you can call crow cams and enquire about a towing camshaft for you motor, it will make the difference in rev range that you require, and a set of extractors may help with that as well. these modifications will not break your gearbox if the vehicle is driven sensibley. [/B]

*clears throat* did anyone mention that the banjo's in them are weak as piss and will go before the box does?

[project commy]

good point they are as weak as, but for day to day driving it might be ok

Being a tonner it should have a Salisbury diff
