Hot diggidy, I bet that makes for a fun street car.

Good #'s.

Not exactly a stock block if it has pistons and rods.

no its still a stock block, with other than stock internals. I think he means its not sleeved.

seriously, i dont have an aftermarket pump or regulator, but im maxing ---- out on my supra 440's (and it still goes lean at 18psi and up)

Look at the size of your turbo :P 60/63 vs my 48/60. I could see how it leans out it flows a shitload more.

you do realize the jdm d15b head is the same as a d16z6 head with a different cam, right?

Exactly why I picked up my Percision 680cc's when I had some paypal money sitting around.

FYI The dyno dynamics dynos read low compared to a dynojet. So...for compensation theres a 10% difference wich would put me well over 300 (around 327whp) in comparison. As for the cam in a D15B head thats still debatable. Although the keyway is different that is for sure, theres still no 100% proof of the lobe lift and duration. I run a Y8 cam gear to get correct mechanical timing if anyone was curious due to the deck height difference bwteen a Z6 block and a D15B block. I still need a shitload of tuning as right at VTEC it would go a little lean in the 13's and richen right up. My a/f was all over the place and tonight I will post it up for you non-believers. The graph clearly shows 21psi spike (long *** vacuum lines to my boost controller) and holds at 20psi. The a/f right around 4600rpm dips in the 13's (rises on a graph) then goes way the hell fat at 10.5:1 and drops more through the powerband and even off the chart into the 9's. There is definatly HP left on the table but I feared cylinder wash with it that rich. I think with some tuning I should be able to squeaze a few more ponies out the 450's. I would like to shoot for 330 to the wheels on the dynamics (read that as 360ish dynojet) but we will see. Sure thats a lot of boost on stock sleeves but its the HP you need to look at not so much the pressure it took to make it. Imagine if I had some headwork, larger exhaust or even open dp and I tossed in my 660cc's heh...nah dont need it. I'm happy with it. I look at it like this, between the turbo setup and engine work I am well under $3k. 300hp is darn good when you consider what it cost for a B swap, turbo and 300whp.
