Ian

I have finall installed a reconditioned normally asperated Sigma 2.6 Astron in my Mitsu L300. Fair enough I am only on my first 1000Km but I am doing 20ltr/100kms. What can I expect when run in and tuned. I have 14inch rims on at present but I am looking to put 16inch rims on. I tried some mates rims and the extra long legs were outstanding

Not an answer to your question but I have 5 chrome 15inch wheels off a 1990 pajero in excellent condition looking for a home if interested.

Cheers

Why not run bigger tires on the smaller rims?

31inch tire on 14inch rim and 31 on a 16inch are same diameter, should be the same??

Depends what size rims they are. they are probably only 5.5 or 6 inch rims at best. Wont fit 31's on them I would think. You would want, minimum 7 inch rims for 31's.

Depends on which width 31 you put on there.. its the width you worry about not how many inches round.

9.5 will go on a 6inch rim..
10.5 would be better on a 7...
11.5/12.5 would be better on 8..
13.5 better on a 10in rim.

Great motor for the L300, Plenty of torque in those ones but unfortunately they have also been reputed to suck more than the proverbial.
They get bleep ty economy in a sedan and you got it in a 4WD. It should get better when sorted but don't expect too much. Be interested to see the final figure in that vehicle.

Had a 2,6 astron in a sedan, best 20L/100, eventually discovered thermostat faulty, never got hot enough for auto choke to cut out. Replaced it and got 15L/100

It's a thirsty beast.

And watch out for those harmonic balancers their really mean muthers.

Ian.
YOu Should be able to do a lot better than 20, is it an unleaded or leaded motor? The vacum advance on the unleaded was a problem, the vacum unit from a holden [bosh] will srew striaght on and give you better power, check the moving plate to see if it rotates smoothly if not pull it to pieces and clean, watch out for the tiny balls that will fall out. Good luck Eric.

Hi Ian,

I've helped plenty vehicles reduce their fuel consumption by making the engine burn all the fuel, not just some of it. I should imagine the exhaust tail pipe is rather sooty. This means there is a lot of unburnt fuel goig out the exhaust. I believe that I should be able to help you.

Contact me and I'll explain the details to you.
