intake manifolds for the Optimizer 6.5's

[res0wc18]

hey guys figured you would be the one to ask here.

I know that the Optimizers have different intake bolt angles vs the non optimizer/NA engines.

these look to be correct hats.




question is what goes after those? this?




trying to get this figured out as I'm wanting to run a marine engine optimizer and cant find a diagram of the turbo engine intakes.

found a diagram. i believe those are the correct parts. looks like it feeds from the bottom.

You got it. I yanked my 6.5NA & installed a 2007 6.5 Optimizer Turbo in my M998 last year... got those exact parts (plus a bunch more) to make it happen

awesome. from what i can tell and have been told the older CUCV type single stat crossover pipe etc will fit and the only real difference is the intake manifold for fitment of accessories etc. so only real must have is the above intake setup in some form, the rest of the civy or CUCV style stuff will fit.

Did you find that to be true?

I used my same 6.5na coolant crossover single stat pipe. I used the complete turbo setup , so had to get a new exhaust crossover from turbo to muffler. (Already came with turbo manifolds) The turbo top end is lower comp. for the turbo.... I upgraded my injectors & turned up my fuel IP also. Man that turbo kicks butt over the NA.
