i am going on a b18c with 83 mm piston everything internal upgraded with a t3 4 e hybir 0.53 0.60 stage 3 turbin wheel ,please give me info for my tubo,now i am using a b18c non turbo but 83 mm shd i use 8 spark plug will it be too cold? 0.1 bar is equal to how many psi i am thinking to have 16 psi.Should i considere a 81 mm 81.5 or 83 mm please answer me

some one please reply

 

1 Bar = 14.7 psi

#7 or #8 should be fine
14.5psi = 1 BAR

as far the other stuff...thats all up to you...but you can't bore an OEM block to 83mm, you'll need to sleeve it

14.7 is atmospheric

so does it means if i am using 81 mm is better what is the difference of the piston size?

The difference between an 83mm and 81mm piston is about 2mm.

Good sized turbo.

I don't see what it is that you wanted to know about it.

Nah. It's fine.

0.1bar = 1.4696psi. On the other hand, 1 bar = 14.696 psi.

How would we know? What do you want to achieve with the engine. Also, I'm curious if your keyboard is missing some keys.

Aside from the physical differences, a larger diamater piston will deliver more hp, more torque, and burn more gas.

if you wanna get technical 1 bar = 14.503


Not sure where you found your answer.

I think he's thinking of Atmospheric Pressure

14.7psi = AP
14.5psi = BAR
14.2 = kg/cm2

W3rd. If one bar is subbosed to equal 1atmosphere, needless to say I interpreted 1 bar as 14.696 (101.3kPa). As it turns out, it's rounded off to 14.5 (100.0kPa) for ease of use...Brilliant!!

 

i am targetting 400-500 whats is the best piston?what i mean is what is the best size

http://en.wikipedia.org/wiki/Turbocharger

"At 100% efficiency, a turbocharger providing 100 kPa (= 1 Bar or 14.7 PSI) of boost would effectively double the power of the engine."

Andre, I was on the same school of thought, but through the dumbification of the world, I saw that the generally accepted kPa for 1 BAR was 100kPa. Just to make things easy for the simple mind. I'm still going ot take to the grave that 1Br = 14.696psi which is one atmosphere, but now I am aware that in some cases, some parties are propigating that 14.5 = 1 atmosphere or 1 bar.
