Lol...not that I'm set of using the MHI flange, it's just one of many turbos I have laying around collecting dust, and one of the few that need little work to be fully usable. And since the stock 6cm^2 housing is melted up a little from the previous owner, I figured I should at least replace it, even if I turn around and sell it instead. Budget has always been key word in my builds, and this one's unfortunately going to be no exception. Although I do have that old garrett .48/.60 laying around that's in serious need of a rebuild.

It's Bullseye power that makes the new turbine housings. The stainless ones are supposed to be pretty badass.

that is what i've been saying for years i love the ------- 14b



i think its one of the best turbo's ever built

I just read through the website...he's still using the 6cm^2 housing, but ported. Simply amazing that the 14b will keep making 20psi at 7000 rpm's on a 4g63, that definately gives me alot of hope for my 1.8 liter.

4G63 with portwork and cams doesn't have the flow of a stock LS cylinder head. You try and push 20 psi on a 14b and it'll be an unhappy day.

your negative becouse you hate everything dsm

HondaTuner

You just now figured that out?

What's the portflow numbers on a b18a1 head? Not that I'm going to use on, but last time I looked you were doing good if you got a b16 head to flow 300cfm. Here's stock 4g63 portflow...
INTAKE

.100 lift : 78.44 cfm
.200 lift : 149.94 cfm
.300 lift : 204.33 cfm
.350 lift : 217.56 cfm
.400 lift : 224.91 cfm

EXHAUST

.100 lift : 84.42 cfm
.200 lift : 170.2 cfm
.300 lift : 204.88 cfm
.350 lift : 206.45 cfm

Was measured @ 28" of water. Supposedly from what I've read as well, 2nd gen heads have better head castings, and with port work will flow very well. I still want to try this 14b/7cm^2 combo just to see what it'll do, should be interesting to press it to the limits on a b-series motor, although I'm sure it'll be way out of it's efficiency range at high psi numbers. Water cooler anyone? Might look into water injection at the same time...hmm.

No, I like the 4G63, I just hate everything *attached* to the engine. This doesn't mean that I am not wholly correct in my statement that an LS head flows more.

I went through this with some DSM asshat in the HT HX35 thread, he threw the same bullshit flowbench numbers at me - if you want the detailled break down of how I broke one off in him feel free to check there, because it was a multi-faceted argument that he lost on all counts. Most significantly, what the DSM asshat couldn't provide me with were DSM power numbers that could hold a candle to a stock head LS dyno graph when I was more than willing to let the figures be modified to reflect AWD losses and totally discount the difference in engine displacements.

There's a lot more going on here than junk flowbench numbers - the quality of the flow in question is pathetic, the actual flow dictated by bottom end geometry is pathetic, etc, which is why DSMs take 1.9 million psi to break 300 whp. DSMtard wanted to make effeminant hp per psi comparisons - which is all comparing headflow on turbocharged cars is - and got his dick put in the dirt because he lacked a clue.

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.

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?

Does anybody on here know the stock flow numbers on a B18a head If not does anyone have the small bore size adapter for a superflow? I have a flow bench and a stock head, but not the 75 bucks for the adapter, just because I don't care that much.

PS Smallest bore I have is a 3.75 inch
