626 manifold

[spicyprotevo]

i don't necessarily need low end torque, but it would be nice to have something that is unique. everything that you guys are saying is nice, and there IS a lot to calculate, i agree with that. i know i "don't know what i'm talking about" but why shoot down those who try?
i've been messin with my KLDE head forever seeing if it's possible to put a VTEC solenoid on there to have 2 cam profiles (fuel economy and NA power). i know people that have done crazy things to engine parts, but i wanna get as far as i can on my own, to see what i can do.
i don't wanna go crazy custom on my MSP (daily driver), so you're right on getting a 626 manifold. but i would love to do things like this on my VRIS mani on the KL.

gaskets;
FS01 13 655 - throttle body
FSJ2 13 111A - intake manifold

use carb or brake cleaner for the cleanup

Ken,
How about the EGR tube part number?

Thanks!

krazie: true, but as you also said the gains are minimal

it definately is a lot cheaper mod than the 626 though hahaha


spicyprotevo: I do want to apologize for my brashness lol, I was kinda bitter the other night
but you realize that you can not add vtec to a non vtec head, right? it's not as simple as adding an extra lobe to the camshaft, there are many more components to a vtec assembly than just the cams....it simply is not possible on a KL head unles you manufacture an entirely new cylinder head for the car from scratch....if you want fuel economy and power, then stick with your stock intake manifold because it is already designed for this (the butterfly valves are for fuel economy as well as adjusting the length of the intake manifold for a smoother power band), but it is definately NOT possible to put vtec in our cylinder heads...

why do you say that? anything is possible. my friend, who is the Hawnduh master, and i have compared heads and it CAN work, now whether I'll be able to get it to work is a different story. you're right. i would need a different head and type of cam, but i was thinking other methods... someday. when i have money. anyways, this isn't a thread about kl's or heads or anything like that, so we should "argue" about this via PM or a different thread.

 

[neox.286]

lol, because I know it cannot work unless you have an entire new head fabricated, but why you would want something that limits your power until 5600 rpms makes no sense to me

you do realize that vtec is actually a power restrictor and not a power adder right? vtec is designed to give you fuel economy by stripping the engine of it's power until you decide to rev it out to a certain rpm level....

not to mention the fact that it just is not possible unless (again) you fabricated an entirely new head....which is entirely pointless, you'd spend thousands of dollars having a shop make it and then in the end loose power or make the same amount of power you do now until 5600 rpms....then have to shift right after that before the exhaust camshaft even opens up?

hahahahahhaah vtec mazdas ftw haha i thought i was the only vtec mazda damn it
on topic though i love my 626 mani haha

not if you leave the stock kl cam profile as your mpg one, and then get a serious lift and adv for the high rpms that way you don't get and lift problems or s**** like that.

Why dont you just put a B18C in your car, it would be a lot cheaper. I think i would trust the years of R&D honda has in its VTEC motors than trying to make your own. Thats if you like that sort of thing.

oh my god, you don't know s*** about motor design...go to a professional shop and talk with them about it, you might understand then...

thank you for making some sense here

honda designs the motors based around the concept of vtec....including tuning and highly elaborate ECU design...vtec is not something you can just plug in and go, you can't just drop in a vtec camshaft and expect it to work...here is a diagram of a SOHC vtec head

you see the entire rocker arm assembly that mounts on top of the cams? you would have to find a way to custom fabricate your own rocker assembly that will mate up to the mazda head, which means you would have to custom design an entire new head with proper flowing oil passages, etc...

I'm not going to say it cannot be done, but the cost to have it done and the amount of knowledge and mechanical design skills you would need are immense...there isn't one guy at honda that sits down and designs the entire motor, it is a team that has spent years designing this and they know all the tips and tricks of it...they have the tools, and the budget to spend thousands designing a cylinder head that utilizes a proper vtec assembly that has been proven and works

ugh all this talk of vtec...

p.s. the last picture is the funniest.
