Hey im new but im building a d16y8 and with a vortech supercharger,i want to get some ideas and some advice on the supercharging because the d16y8 in high compression and ive heard thtat to turbo or super a d16 you need to sleeve the pistons,get new pistons many many things but i want to hear input on others who have built their d16's so any and all advice is extremely helpful!

 

Sleeve the pistons thats a new one for me.I think you mean have the block resleeved with aftermarket ones that are meant for high loads I.E. the best thing to do it make sure you get forged rods and pistons low compression ones to if you are going to go for forced induction.after that make sure you keep it tuned exactly right for max potential and max engine life.I always recommend hondata EMU/FMU(egine managment unit/fuel managment unit)for any forced induction but there are others with much smaller tag price,and just as good with the right set up.Best thing to remember and do is to, do it right the first time and dont get impatient or you will find yourself rebuilding or completely replacing everything.

 

sleeve, 79mm bore, 9.5:1 compression, forged internals, 15psi = own

 

79mm is way too big for a fi motor. id go with rs sleeves and a 75mm bore. just that way if **** hits the fan u can always reuse your block and just bore over.

how many lbs are you planning on running,better yet how much hp do uwant. stock d16s typically max out at about 200whp. so anyting after that id go with forged internals.

if u are planning on staying under the 320whp mark u can just get good rods and pistons and call it a day. if u want more than 300whp then id sleeve the block.

those are just my reccomendations anybody else with some help?

uh-huh....

"thats just too much displacement for a turbo"
you make no sense kid

The problem here is not one of 'too much displacement'. Rather it is a problem with the cylinder walls being too thin. Since you are running forced induction, you will have increased cylinder pressure and piston side loading. And you need more material in the cylinders to withstand it without cylinder 'walking' or breakage. I am not sure what the limit is on a D-series motor. But on a B-series motor, you generally cannot go bigger than 84mm for forced induction. It is for this reason that you can go bigger for allmotor use.

 

notice i said SLEEVE?
