an just a few pounds of boost will make a HUGE imporvement in power.
only 4-5 psi will do miracles with 11:1 !!!

 

having friends who have citroens my advice to you is DONT DO IT

but if you wanna as they say - its all about the engine mapping - i would n/a it or supercharge personally

 

i've thought of going NA but it's too much money for too low power gain
i think i need a good way of lowering compression rate then there wont be any problem with turboing i guess... well two head gaskets and a decompression plate seems to solve this problem but i still havent decided because im not sure about this plate's reliability... do you recommend this solution??

 

i've been driving for a long time with different engines with a decompression plate, never had any problems with it.

It is being used on vw's a lot too.

 

do it youll love it even if its only 5 psi. I got a 11.1 sbc 350 dialed in on 7psi an it runs out good.....
