can anyone tell me what the correct compression should be for a twin turbo.

i need to know as i have to do one.

urgent

 

Anywhere between 120 & 150psi but not more than 10psi between all cylinders.

 

Steve

 

thanks alot.

 

 

"Not more than 10 between all cylinders", yours and mine both had the back right and front left 20psi apart, ranging from 120 to 140. Must be okay, I hope!

 

Anyhow, I always use my halfords dual foot pump to pump up my cylinders in the morning.

 

A complete rebore with oversized forged pistons will cure that Jez!

 

I think JE 8.1:1 will do nicely :-)

 

Steve

 

 

 

Um! forged pistons. Yep, I can't wait for xmas heh Craig?.... Craig?.............(the sound of beautiful birds tweeting in the silent background)

 

ahh, the peace, the quiet.... ;)

 

yep, after xmas i think it will be party time for my engine !!

 

i just found out that the JUN pistons are made in the UK, so i am on the trail...

 

i think you'll find the jun items are made by cosworth engineering speak to steve ellerby he is already on the case

 

Lets talk wonga, how much?

 

Are we talking GB here??

 

have you had prices for them yet Steve ?

 

If the price and timing is right, i might get some in ready for when i do my rebuild...
