cylinder head xud11 12 s

[niciou]

My 60mph-120mph is under 10seconds...but I am guessing my car is lighter.
I cannot speak for the 8v head...as i have not tried it.
But the 12v head with float valves above 40psi, roughly.
12v head will flow more. But I would still say you need a different turbo.

I understand that I must change turbo but what turbo? my car is 950 kg this one the 306 and 205 heavier.
in theory
You advise me what turbo?
your engine well-tien 40 psi and 210 hp xud11 I know its very solid, its yours to you after how many km with your performance?
