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.

 

4g63 combustion chamber sucks ***. The valves have more shrouding than a smallblock ford, and the lack of quench area+ shitty ic, intake, etc. leads the engine to be prone to knock at realitively low power levels. In fact, this is one of the only engines still in production that you have to "tune for knock" For the record, the 4g61 head has a much better combustion chamber, but flows poorly comparied to the 63'
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.

 

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.
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.

 

2G 4G63 shouldn't be mentioned in the same forum as 1G 4G63. If the man was building a 2G it's due to INBREEDING.

 

Only good thing I've read on 2g heads is you're able to port them to flow better than 1st gen, but mind you...that's second-hand info and not something I can vouche for firsthand.

 

14b on a sohc is a ------- great match up

 

Damn right it is. I've been tempted a few times to sell off all my b-series motors and just build a D for much less money with another 14b. Most fun I ever had with any motor, B or D series.

 

Actually there was a guy with an all out race FWD that went TENS! I'll See if I can Find the link

 

I already posted the link. Post #17
