G'day all,
Just wondering if anyone out there has had any experience or knows of anyone that has modified the toyota hilux or Prado 3.4 litre V6? I know that off the internet in the states that the V6 responds
well to the Trd exhaust but we can't use it here because of the american design exhaust manifold interferes with our steering column because it's the other way around. I'm not keen on spending $7,000 to get a TRD supercharger either. I just want some more low down torque out of my hilux, because the tyres (265/75x16)_ have taken abit of the power away. Does anyone know if theres a stroker kit for this engine anywhere?
Go hard or take it
home!

If you want more low down torque I would have thought a t/d diesel is the way to go, but you can't change cars hey..? I wouldn't be playing with stroker kits and the like on an engine like that, you could risk losing the Toyota reliability. You would be perhaps best served by getting a custom exhaust manifold built to suit along with some other exhaust mods. The exhaust manifold should be coated with somethign like High performance coatings to reduce heat. This could easily give you 15% more low down torque. I have the new Lux Turbo Diesel and the low down torque is sensational.

This is from a previous post of mine when asked about a Prado a week or so ago:
You can change the main muffler for a straight through type. Will increase the noise a bit though.
Check out www.lcool.org and there are links to a Yahoo group. There has been messages on there about performance improvements. Basically they are the muffler ($400 or less), a UNICHIP ($1250+) or a supercharger($$$$$$). The later is the best, some will argue that the other two don't have any real noticable effect.
I own a 3.4 V6 Hilux, and changed the muffler. Its a bit noisy now, but it does go slightly better. The Hilux would be much different in the noise department than the Prado, as the Hilux has virtually no sound deadening.
I believe there are even extractors on the market now, but they are expensive to fit due to the tight confines of the engine bay.
I was going to get a UNICHIP, but my lease is up in a year, so i don't think I will bother. Would be good to drive one with a UNICHIP to see what its like though.
Supercharger is the way to go, brings it up to nearly the power of the new 4lt V6 Prado, but it would cost heaps, like $5k at least.

I have investigated the Supercharger and would suggest upgrading to the new Hilux to get a new car with warranty instead. I've been seriously considering it - like the sound of 175kw and extra torque.
I have had a big pipe and sports muffler (around $200 fitted) on mine for years with a K*N airfilter. Very loud - sounds like an old valiant -
well actually sounds pretty good. Mine is an auto, so a manual would sound heaps better.
I've just been recommended to go new tyres at 31x10.5 (10R) in Cooper STT. Slight increase in rolling diametre might have the same acceleration effect on mine, although I was hoping I wouldn't notice too much.
