dont have the specs to go off and the guy that did the head said he didnt have anything to measure the bolts properly....and found some ARP studs for $200 delivered so will just go with them

i'll leave the computer to sort out any knocking issues...i assume it has a knock sensor for a reason

compression is ok IF you pull enough timing out
any boosted engine will lunch itself if it knocks (even once) it doesnt care if you have forgies, a metal head gasket or arp studs
you cant have boost and compression and timing
use the old bolts if they are within spec

it should hold together ok on 10psi....it will go bang if it annoys me enough for me to decide it doesnt really need a wastegate

but until them i'll just assume it will be right

as far as i know its th pistons that change the compression ratio

and its only the lack of oil squirters and the pistons that are different, maybe the rods also

will see how it goes with the DE pistons, as it should be nice and responsive and make some decent power with the extra compression
i like the thought of zero lag

All that mucking around...
Is it just the pistons that are different between de and det bottom ends?
I assume oil sqirters etc but what I mean is it the pistons that determine the compession or rod lenghth?
Reason for asking is I have a set of good (used) det pistons here if you want them.

Ive built a few motors and they are not reusable. Can be picked up fairly cheap though, not worth risking. They are built to stretch so I'd throw them away.

If Nissan says they cannot be re-used, then I would not re-use them.
