loudsubz, is B vtec like... B for bull****?
does anyone know about secret VTEC, like dx Civics have it when you pop your clutch in 3rd gear but stay on the gas, and quickly release the clutch, it engages secret VTEC?

man, there are massive articles on this on TOV (temple of vtec)
we're not gonna reproduce the entire article here, when someone has already taken the time to explain it all. in addition, it's been looked at in depth in many automotive publications.

That little thing called sarcasm, I get ya. =)
Somewhat off topic but if you want something interesting to read, check out the new BMW 3 Series engine. Magnesium/Aluminum block, Valvetronic, Double VANOS etc. Much Technology in that.

BMW 3-series I'm most impressed by simple, effective technology rather than the technology for the sake of technology (which is what BMW does).
Ok, I'll tell you why I hate BMW so much... I respect that they build sweet cars for the average yuppie. That's cool. But they do things that are not ideal/optimal for the car.
You can not find that kinda waste on a japanese car... even a luxury car. I'll take Acura or Lexus or even Infinity over a BMW anyday. M-B AMG are a lil harder to resist though
What I like is for example... individual throttle bodies. That's sick 'technology' even though it's not technology at all. What I like is adjusting valve lash... cuz it's simple and mechanical. What I like is VTEC... cuz again it's SUCH a simple concept. What I like is the Yamaha built Taurus V6 with 245hp back in like 1993. With the dual length intake runners. That's sick.
For the love of God, BMW Gmbh. buys engines for MINI Coopers from Chrysler

it's okay, this thread was crap right from when bronx learned to use a computer hahaha
and for the record... yes, I even like pushrods
they have their place in history... like mechanical fuel injection ( 
Hilborne injection). I look forward to reading that link of yours trackhack, its good to stay on top of the tech. but I doubt I will be impressed. Did you read about the ultra-lean K-series?? I forget now but I think they said 45:1 air/fuel ratio????? oh yeah!

Well if this ISN'T threadcrapping I'll continue.
Sometimes I don't understand people hating on pushrod engines, especially in a performance application. When GM set out to redesign the small block for the Corvette(LS1) the chose to keep the pushrods for simplicity and weight (lower CG) purposes. Gm's reasoning was such that they could create a smaller lighter package by keeping the cam in the block rather than sticking double or quadruple the number of camshafts and componetry up high on the cylinder heads. If you've seen the size of a ford modular V8 then you know what GM is talking about.
I saw the Direct Injection K-series engine, and I was quite impressed with the simplicity of its operation. I think direct injection gasoline engines is the next step in technology aside from hybrid technology.
The BMW engine (Link Below) I find interesting because of the different use of materials in its construction, especially for a mass-manufactured consumer vehicle. Check out the mould for the block as well. Here ya go:

nice link!! bottom line is... VTEC made variable valve timing possible on mass-produced cars. and that's hot!! BTW, you know we can get elec waterpumps for our cars... well at least B and H series engines? right? it's nice and all... but the ultimate engines to me are still Toyota V8s as found in their trucks and in Lexus cars. 
BMW does make one silky smooth straight six though.

Honda introduced electric waterpumps back in the S2000 years ago, so I agree that it's nothing new. The electric waterpump addition to my car.. I don't think I can do that, it's just not JDM yo. j/k
Toyota V8's? Honestly I think they are ok(Toyota Reliability) but far from simple. I come from a mechanical background and I like stuff that is easy to work on. I know an experienced Lexus mechanic and he HATES them, especially for chasing electrical gremlins.
I liked the LT5 in the ZR-1 vette as it was an extremely compact package for it's technology.
Favourite automotive engine? Going on sound it has to be the Callaway 7.0L 32 valve Naturally Aspirated V8 that was in the Aston Martin Group C Race car. It was on Victory By Design on Speed channel. Otherwise it would be a JUDD V10 or a 911 GT3RS engine. Can you tell I'm into Lemans cars?

haha yeah Lemans fan indeed... I'm more of a touring car championship fan... cars are 'closer' to being production cars. Like BTCC, ATCC, USTCC, DTM, JTCC and so on
fav engine... there are many that come to mind. 502, 454, 460, 383, 347, 302, 426, 427, 429... then there is the F20C S2000 engine, and then the NSX engine... then the SR20DET, the RB26DET... 22R.... then the VW air cooled flat fours, then the 2 liter 16 valve GTI engines... then Mitsubishi Eclipse/Talon engines... Conquest engines (despite all the head cracking), then we can get into diesels... power stroke, cummins, duramax... I mean... some of those can get 1000 lbft of torque and 500 hp with the Gale Banks kit. Too many cars/engines and not enough money.
Oh... and then the Insight drivetrain I think is revolutionary.
