gday rox.
i havnt fitted them my self but i did have one in for a wheel alignment a cpl of months ago.
this thing had extractors and big exhaust and went like a petrol motor.
i actually stopped half way around the road test to listen to it idle to make sure it was a diesel.
compared to other diesels it made a big differencelooking foward to september(landcruiser park/fraser island)

I would put the $$ towards a turbo and keep saving i know someone who did the same thing and put a turbo on a month later. ( i will find out if he still has the extractors might be able to get them cheap)

Pardon me for asking such a stupid question, but what are extractors? My native tongue is not english (especially aussie english) and I have never heard this word used. So what is it?

Hi Molopaa,

They are also known as exhaust "headers"

Extractors (also known as headers) are a replacement for the standard engine exhaust manifold. They create are a better and more even airflow drawing the exhaust gases from the motor hence the term extractor. A mechanic will explain it better but that's it in nutshell.

In most cases, petrol and diesel, they can increase power and engine will run smoother. Some say an increase in fuel economy as well but in my experience, just the same.

I had extractors fitted to a Mid wheel base petrol cruiser, FJ75 I think, with a petrol 4.0lt 2F motor. I also put on a 2 and a half inch exhaust with turbo muffler. What a difference. The most noticable change was how queit the engine idled but it also cruised a hell of a lot better.

Best money I ever spent on that car...
