Re: ITB's are for V8's!!
That "SpankinV8s" guy is a moron, and the sad part is he likely came from this forum.
"you think american cars were the first ones to ultilize itb's??? ya right lol bmw has been using them for years from the factory . same with early porsches."
GM introduced the world's first production gas fuel injected automobile in 1957on a 283ci small block. A BMW wouldn't have fuel injection from the factory until 1969 when the 2000tii was introduced.
Early Porsche? What exactly is an "early Porsche"? Fuel injection was introduced on Porsche models in 1974 and it was the same basic Bosch Jetronic system you could find on a BMW or Datsun 280Z. Wasn't exactly hard to come by at this point in time and being that it's some 4 decades after the company was founded it wouldn't call it early.
ITBs gained wide spread popularity with the classic Hilborn fuel injection systems during the 1960s. Hilborns are very distinctive looking with their tall ‘horn’ type stacks.
Modern recreation of Hilborn style injection system.
They were used in virtually every type of racing and were THE origin for the ITB fuel injection system.

Re: ITB's are for V8's!!
I love the jerking off comments etc......make me happy i was never really in the scene...but sucks to be put in the same category as some of these morons.
I'd also love to see that dyno sheet for that "dc5" with 290whp, im sure its possible but curious none the less. I know people have built b20 vtecs to mid 200's.

Re: ITB's are for V8's!!
Although I think gold and chrome are super ugly together (tack-O), I still think that all of this is a stupid and pointless argument. I will say this though: How many V8s are making over 100HP/Liter? They're out there, but they're rare. It's the technology that's impressive, and how far its come.
I'll blast ugly Honda engine detailing all day long, and not matter what, it usually doesn't hold a candle to domestic V8 engine tackiness that's everywhere. Funny color engine paint, dozens of brands of stamped steel and billet valve covers (and the ugly easy off fasteners), chrome timing chain covers, chrome alternators (why???), neon yellow spark plug wires, unequal length shorty headers, carburetors (snuck that one in) it's all too painful to talk about. Oh, and I hate chrome, I should probably mention that.
It's kinda interesting that Honda out-of-style is stuff that went out of style a few years (or less) ago, whereas domestic ugly is stuff that went out of style decades ago. Yet people still bolt that crap onto their shadetree hot rods, and it's still a huge market.

Re: ITB's are for V8's!!
it's a valid question. you can't tell from the picture what's under the tb's, and there's a pully hanging off the right of it.
it would be a roots blower sucking air from the tb's and blowing air into the head.
i know this wouldn't make any sense at all from a performance standpoint, but looking at the picture and having any general knowledge of how a supercharger works, it's surely possible.
edit: and feel free to argue. i can teach you all about how forced induction can pull instead of push.

That's definitely and clearly an idler pulley, you can see the counter bore for the bearings.
