alright so I have been wanting to run the 62/65/12 or maybe even the 14 housing, With plans that one day I will make it a twin set up but for now I didn't want to have the head o-ringed I have head studs right now. I plan on 550 hp range but for now I just want more power then I got so I can be happy with a 62 while I wait. but im wondering if its a over kill if I should just rebuild my hx35 and put a s400 under it.

 

62/65/14... all the way

 

and you say the 14 over the 12 housing?

 

Yes get the 14cm over the 12cm.

14 will have less drive pressure, might lag just a smidge, but for twins it would be the most usable.... The 12 will hold pressure back causing high EGT's and could lead to the issues...
