i must buy new sleeves and i'm wondering about darton 200series for my b16a2, it will see max 25psi, so what do you think guys about this sleeves?
one of my friend is using 300 series in his h22 with 22psi daily and 30psi on races with no problem,
so is it worth ? are they little bit stronger than stock ones?

 

Darton uses ductile iron for their sleeves so all of the sleeves are better and stronger than the stock sleeves. I beleive the the differance in the series is thousandths of thickness but I'm not 100% on that, last time I talked to darton I forgot to ask.

 

thx, nice to hear it
