extractors and exhaust

Todd I would recommend for just about any thing Landcruiser you try the Lcool.org web site. I would imagine your answers are already on that site.

Some one on this site may have your answer but the Lcool site is brilliant for that sort of questions.

John.

cheers John

Todd,
I agree that LCOOL is the place to go.

If you have a non-turbo engine then I doubt that you will find enlarging the exhaust will make much difference. You are saying 'putting extractors on'. This is more what is done on a petrol motor. On a diesel the normal approach is to enlarge the dump pipe and exhaust but this will only show real benefit where there is significant back pressure as occurs with a turbo engine.

I've never put extractors on a L/C but have on two Hilux diesels, not sure if the results were worth the trouble though. Never noticed any power increase at all; however, the fuel consumption improved by about 1-2 LP100. Considering the price of extractors I wouldn't bother! Almost any exhaust shop can supply and/or fit, I got mine from Carline in Rockingham.

I'd suggest you save the dollars, and put them toward a turbo kit. Will get more bang for your buck.

Have seen a few 1HZ's with extractors/exhaust...sounded alright, went okay, but still pretty breathless.

I put extractors & 2" exhaust on an '82 Hilux diesel. Might have improved it marginally, but sounded good. :-). Bit of a case if you add 10% to almost nothing, you've still only got 10%.

A lot have turboed them but then if not careful blow the bottom end. Lcool will tell you the good and bad about 1HZ.
The 1HD FT or 1HDFTE motors were far and away better. Dont know if what you want to do will make it any faster.

A friend bought one and constantly regretted it as it crawled up hills with a van on and wasnt very fast on the flat when towing either.

As said a bigger dump pipe is the usual I did that and a 3 in exhaust on a 1HDFTE and it went better but then it went pretty good before I did it

Hi Todd S4, I just put a Pacemaker 2 1/2 inch system with extractors on my 1hz troopy. It was a fairly straight forward diy installation. Just had to cut the old exhaust off as the flange nuts were seized and also replace engine studs as the nuts had also seized. I didn't want to go down the turbo road but just wanted a little more engine response. The car now accelerates alot smoother, is better on take off, on hills. ( for a 1hz anyway.) It also feels alot more relaxed at 100 kph. Downside is less engine braking and very slight increase in fuel due to it accelerating better off the line. It has made the troopy, for me, more comfortable to drive. Cheers.

Hi Todd,
I put a Beaudesert Exhaust kit onto my 2003 1HZ powered 100 series, it included Pacemaker extractors and stainless system. While it doesn't make it a rocket ship the increase in power was noticeable while driving so maybe 5 kw as a guess. I am reluctant to turbo an engine that was never designed for it. I tow a 2 tonne caravan and with patience we get there. Price was $600 second hand - thanks to Gumtree.

You actually have a HZJ105 series Landcruiser.
The 100 series is for the Independant Front Suspension model.
Save your extractor, fat exhaust and turbo money and do it properly.
Fit a 24 valve 1HDFTE engine and suitable gearbox like Toyota should have done to the 105 series.

I have owned 3 turbo 4WD's but have also had extractors and larger exhaust put on 2 non turbo diesels. They were older 4WD's a 2.4 ltr 4 Runner, a 60 ser cruiser it made both vehicles more driver friendly than they were. I would recommend getting a quality system where they match the exhaust to the extractors/headers while they may not be cheap it will be worth it and you may get approx 10 to 15% improvement in power it varies from one vehicle to another. Realistically economy should improve slightly after time because when you get them you'll be a bit heavy on the gas pedal having fun playing around with the extra power you now have then you will eventually settle down back to how you use to drive everyone does it . You will notice even more improvement if you compliment the exhaust by doing the intake side by fitting a snorkel and furthermore again by fitting an air filter like a K&N if you like.
