Re: Got my 14b LS back from the Dyno!!
Alaniz used to have a bunch of stock flowcharts up on their website. 28" water, .500" lift, I'd guess in the 205-215 range. With pimp valvejob will flow as much as unported VTEC head, 230. Highest I've ever heard of stock are a couple ITR heads (quick and sleazy factory ported) in the ~240-250 range - the one I touched made 191 whp stock longblock with boltons.

What the 4G63 has going for it is the ability to take a fuckton of heat and never fail, and the ability to handle a fuckton of power on top of it when DSMtards grow a set of ***** and bolt on something bigger than ****** 16/20G. It's ability to handle large quantities of airmass is most excellent, and this is why Joey likes it.

JD is right on target about the heads. Big ports do not equal a high flowing head, or an effiecient engine for that matter. This is one of the many reasons I'm building a Honda and will not own another dsm.

Re: Got my 14b LS back from the Dyno!!
I fully understand what you're saying JD, and I won't argue any of the points you made either. As far as i can see it, the only thing nice about a 4g63 is the cast iron block, everything else is pretty much like you said...junk. I've had to rebuild my friend's boss's 4g63 3 times so far, 2 times because of crank walk, and once because he over-revved it and lost all the rockers.
All of this has -->zero<-- to do with the fact that an LS will max a 14b well before 20 psi. Hell, a SOHC sucks one dry at 14-15 psi - you are aware of junk flowbench number discrepancy between D16 and LS heads, aren't you?
I'm aware of the LS/14b matchup. Honestly I did like the way it ran the last time I did it. I'm not a big fan of waiting for boost until almost 5k, I like quick boost seeing that the car is mostly street driven. I loved the response it had, 8psi by around 3200 and ripped hard all the way to 7k at 14psi, then started dying off a tad but only by about 2 psi. Only problem was I had to crack the wastegate open a hair, otherwise it would spool by 2200rpm and would detonate like crazy...which I blame on trying to use a vafc for managment untuned. The larger exhaust housing should help out some, and now that I have a straight exhaust (instead of the standard EF way-too-many-90's exhaust) it should do a bit better. Honestly if money wasn't such an issue, I would look into larger t3/t4 setups.

In a very lightened/stripped FWD DSM its been all the way down to 10.8's I don't recall whether they used the 6cm exhaust housing, or swapped to a 7cm.
