rebuilding again... need advise for fuel economy 4 turbo
Ok i had a build engine with weisco pistons and it made 200kws at 20 psi.
It seem to be uses a lot of oil like 1L atleast per 1000kms, and chews lots of fuel, it has 805cc tigie billet forged turbo cams and 9.1 compresstion
Now i am rebuilding it because it had low compresstion in cylinder 3, just need some advise on parts.
I am not looking for crazy hp it will be street driven say 95% of the time just want a fast canyon carver and daily driver.
I am thinking of going with 9.5 compresstion for better fuel econemy so sure what people views are but i'll put down a list of things i plain to buy for this build, i really wanted to get this one in 9.5 but they only have 9.1

Hey bossplaya, you should make an intro thread and tell us a little about yourself and where you are from.
Also, give us some more info about your build.
It seems that you have some sort of turbo setup already. Did you upgrade the rods when the engine was originally built?
What kind of engine management are you using, and what is the best fuel you have available where you are?
Unless you have ethanol at the pump or a really good tune, it is safer to run lower compression pistons.
Give us some more information, and we can help you out better.

Well in all seriousness high comp and low boost will be best if you have accsess of high octane fuel, the biggest change i see in fuel economy in my case comes from alignment and oem size tires.
I see a 4 mpg jump when i put on my stock size all seasons.

YEAH I have 98 here so am going with 9.5, also i had 805cc cams, i am going with stock turbo cams now, should i tow my car to tune place before i start it up, or just drive it off boost? it usually runs a bit rich on cold and dont want to risk this bullsht again..
also not surpized with ur mpg rolling resistance does wonder, thak *** i have enkies, i usually only get 250km from tank thanks to this fuking **** blow by but hopefully with the stock cams and bit higher comp, if i get 350/400, i wont complain

Also i should add that i have a torson 3.9, i could go with this MiataRoadster 3.3:1 gearing, can anyone shed some light how much this would help, i'm gussing a 5% improvment in fuel economy
