Extractors on a 1HZ engine

[slr1968]

Has anyone had any experience with putting extractors onto a 1HZ engine?
Is it worth the cash?
Do they make any difference to the power and/or cabin noise?
What are they worth?

Thanks

Shoot a PM to MYTTUF. He's just put extractors on his not long ago. He reckons they don't give you much onroad but when offroad they give you about half a gear. He's pretty happy with them.

What The Fish said

when I first put em on my 1hz 75 series I noticed quite a big difference.

They are certainly not going to hurt anything. Slightly louder but I like that. Depends on what muffler you use too.

If ya can't afford a turbo then extractors and a k&n filter make a fair difference.

I gotta bit of time now.

They were installed along with a 2 1/2 inch exhaust on my 80 and I reckon it picked up a bit of power, but couldn't loose The Fish in a battle on the road (He also has a 80), but noticed a big difference off road where it would stall at a later time, hold gears better and pull better. A noticable difference when climbing hills in low range.
I then installed a K&N air filter coz a mate had one and didn't want it any more. This was done coz I could, not trying for improvement in performance, but it definately helps flow more air.
The misses noticed the noise (80 is her daily driver) but it's not annoying, more a better note. And that counts!!
I got my extractors 2nd hand for $300 and had an exhaust system fitted for $250. So for $550 it was well worth the money.

Hope that helps!!

I fitted extractors and a 2 1/2" system to my 100 1hz, and it breathes a hell of lot better at high revs. But hit a hill and it's back to third or second still. Still 200k and still going, how many turbos get that

half a gear? whats he got in that rig a roadranger?

[MYTTUF]

No Roadranger (unless you call a change between hi & low) but what he means is that you get more outa the car before changing back to a lower gear. Instaed of 2nd being to low and 3rd being to hi, with the motor haveing a wee bit more omph, I can hold 3rd a bit longer, on and off road, which is kinda like having 2nd and a 1/2.
Every bit helps!!
