Should give me around 35% more power, so silimar if not slightly more than the 2.5 in the next gen foz. Plus it will give me heaps of torque which is needed as the 2.0l currently just runs out of puff Ive read of people doing them and driving over 150,000km with them on runing much more boost so the enigne internals will easily handle it. I can also wire it to have a switch so I can turn it on and off when I want just like an aircon compressor.

My engine has to come out this year sometime though as my massive power and economy loss is due to her burning over 1litre of oil ever 1000km. But once thats sorted and with the SC she should be great The charger should arrive in the mail tomorrow so I can work on puttin it in next week once ive moved to Perth this weekend

you should defiantly start a build thread once you have started! i am very keen to see how it goes. might even consider it for my forester!

cool hopefully you can provide enough links and details

Yeah should be able to.

Sorry for the thread hi-jack Richie-Rich. Let us know how you end up going with your Forester.

Thanks for the advice. the tyre guys told me 38-40psi for those tyres... will be reduce psi tomorrow!

As for the super charger im interested. until someone makes a decent 4x4 in a similar size im sticking with my foz.

Rich

PS that is a rad tent set up!

36psi in your tyres is perfect. I run 40 in my yokohamas to improve fuel economy.

32psi is too flat imho.

I tried that and it just stuffed the tyres.

Alex I found out why my EJ20 runs like a dog. Due to the massive amounts of burning oil the valve stem seals are rooted and possibly the rings. Plus its clocked up with 170,000km worth of carbon and gunk that could be cleaned out when these get done. She never used to run so bad. Plus when thats sorted and with the Supercharger on she'll piss along!

Rich, sorry I'm not there to help you but after I return there are some things I'd like to try. One thing for sure is the tappets, probably well overdue.

Hi Paul,

No problems. I totally understand. Whatever you think may help, got lots of return Kal trips this year so the last thing i want is 300k to a tank...

So i now have upper engine cleaner - can someone advise a non mechanical person where is a convenient vacuum hose off the inlet manifold.. yes i did just ask that!

Do tappets affect fuel economy? I'm thinking I need to check my O2 sensor as well...

Upper engine clean has been done.

Ordered a new O2 sensor - due tomorrow

Spare tyre now in the correct place thanks Taza.

Decided to take off the roof basket as i wasn't really using it. Now to see if the fuel economy changes.

taking the wheel and basket off you should see some improvements

Haha, I just put my basket on today. Its gonna have to live on there when I move to Perth in the next few days.

Do you mind if I ask how much the O2 sensor was?

Richie-Rich · Post by **Richie-Rich** » Tue Jan 31, 2012 4:16 pm

Got an ACA (I think) 02 sensor for $125 - Auto Pro

Bosch was nearly $200

Genuine $470...

Try flying to Kal in your plane

I find any small vacuum line nearest to the centre works best.

Yes they will, if they are too tight they will allow compression to escape.

Update;

Roof basket gone and Upper engine clean has been done. Don't have the correct stuff to do the O2 sensor.

Currently getting about 410-430 per 45L tank, which is up 40-50k's Stoked. Engine is feeling smoother so I am happy. Haven't been on any long trips as work has stolen all my previous weekends. Hoping that once I replace the O2 sensor this figures will improve further.

I wish I could Paul, but paying for a plane in Monopoly money just doesn't work!

Awesome. Give me a buzz after the 9th of March and we'll get the car on the hoist and swap out that sensor. I'm hoping to be home (minus some fishing trips) for the full 4 weeks, so see how you go for time.

That damn monoply money doesn't get you very much these days

Richie-Rich · Post by **Richie-Rich** » Thu Mar 01, 2012 12:26 pm

Update;

Took an hour but the O2 sensor is now new. It has never been replaced, looks well knackered. Finally gave in and got some triflo on the thread and out she came.

I'll be calling you in a week Paul, good to catch up and get the car sorted.

No probs Rich.. Just give me a buzz. I did lose my phone last time at Two Rocks.. so if I sound like.. how the hell is this.. it's just because I don't have anyones numbers anymore

Richie-Rich · Post by **Richie-Rich** » Sun Mar 04, 2012 4:18 pm

Update:
Hit the magic 450k to the tank. New O2 sensor seems to be helping. Time to take it for a Highway run to see if it is back to its old self.
