Stock internals on boost
How much power can stock d16 rods hold ? and pistons ? ive heard stock sleeves will hold 400whp ? ,,, if i used stock rods and pistons/sleeves with only acl race bearings and arp rod bolts how much power would be safe ? And what is the weakest link link on a d16 ? Few questions to answer there but can some1 show me some facts on those ?

Re: Stock internals on boost
A stock D can safely make 220-240whp. The weak point is the rod followed by the crap ringlands on our stock, cast pistons. The sleeves will be fine into the 400whp range, but not much beyond that. If you run stock rods and _______ the rods will still limit you to 220-240whp.

shimming ups pressure but reduces flow... all the pressure in the world wont prevent something from spinning if it has no flow.
and yes, y8 bottom ends blow. i spun every bearing + the cam...

i made 307 on e85 stock mini-me, reused headgasket and bolts, and junk ebay parts. only a few pulls though. had to turn it down because i was at 120% duty cycle on 450cc injectors. turned it down to 270 and held up fine. its all in the tune.

Re: Stock internals on boost
The head sucks, the rods don't hold enough for that kind of punishment, and at the rate you'd replace parts to get it even close, you might as well build it correctly from the bottom up. Even the other person posting 307 stated he had to turn it down. It can be done, just not with any probability of reliability.

Single cams are so cheap how could NOT afford to build it? A vitara build can be done fairly cheap with LS rods ( just "notch" the block ) and get headstuds and a HG.

I say just get her on the dyno, make some power and go from there. now adays d series and ls b seires are so cheap that it may be cheaper then just throw a new motor in
