ok, the stock compression of a d16y8 is 9:1 with the d16a1 pistons the compression is 13:1. Now if i were to switch the pistons in my d16y8 with the a1's would the gains be noticable with the compression increase?
i have i/h/e at the moment on my setup, but thats negligable.

If i were to go ahead and do this, what would the pro's/con's of doing this as a N/A setup start?

would it be wise to get arp headstuds for the increased compression? change the headgasket thickness, etc.??

 

bump.

 

someone must know

 

you would get a power increase but your guna need bigger injectors more fuel, as far as the head gasket goes fitting a thicker head gasket would only lower the compression again maybe fitted a higher performance one of the same thickness

 

are you sure this would work for sure that it increases the compression that much? just seems a little too good to be true to me...but idk

 

i was going by the compression calculator found here. http://www.c-speedracing.com/h...c.php

 

stock injectors should be fine. compression will make the engine much more responsive, there have been quite a few board members that have done exactly what you have in mind (ask tom b18c? don't remember the rest of his member name). i know builthatch made around 160 at the wheels with a similar build. obviously your going to want a bigger cam to match the compression and maybe further along down the road some porting.

 

well hey that would be awsome let me know if you find anythign else out about this causei wouldnt mind doing this
