Hello i have a 1994 miata I'm looking into rebuilding for a turbo setup. I'm slightly mechanically inclined more than most but I'm no expert nor do I have any experiences with a miata.I just picked mine up early August. The problem I'm having is there just to many threads that have lead me to no where. For what I want to ask.

Im sure most of us have seen the 99-00 head swap and Honda intake manifold setup.

I understand that the 99-00 is the best flowing head. And I've been trying to track one down for a little while now with no luck. unless I want one that has already been rebuilt with a higher price, which I kinda don't trust, and I'm just gonna have to get it redone anyways.

So my question is has anyone used a Honda intake manifold in a 94-97 head? Is the runner spacing the same? Is there still sufficient power gains? How much of a differences between the two heads when this is done?

i would be willing to buy one if i could find one for 350-400 but i'm seeing 750 or 600 with core **** that

I am certain, that the subject you are asking is one of the easiest to look up in the search. Use the advanced search, intake manifold, honda.
edit:
It is actually 10 threads down from this one, on the same page. Good luck!

Bobbygmf

yeah ive seen that thread...

have you ever read that thread? i got to about page 20, then started from the back read about 8 more pages. unless i missed it. its all over the use of the 99-00 head. and thats not what i'm asking about.and a ******* **** ton of useless comments.

Ask yourself what are you power goals. Also, this should probably be one of the last things you'd need to worry about. Get the motor and turbo setup all sorted. Do you even have engine management, bro? Tons of things for you to worry about rather than having some garage queen motor sitting on a stand with the best parts and a car that doesn't support it. The intake manifold can be sorted at a later date. Be innovative and be the first. Or just go with the tried and true. People make plenty of power on stock manifolds. If you're mechanically inclined, why not make your own with velocity stacks and larger plenum.

I've seen plenty of BP4W heads both on forums and local. You can probably find a VVT head more redily available. Ask 18psi whenever he gets a bunch of parts in.

If you want a great flowing head, just swap a k24

boom. now get to it and start a build thread already.

That's because the NA head fully built and ported, is still worse than a stock 99-00 head. If going natural aspirated, it is a waste of money to mess with the 94 head.

Bobbygmf

Bobbygmf

Do you have money to purchase one right at this moment? You can't wishlist this **** and get it later. When you're ready to buy, you will find em.

You dont know because you don't read.

VVT head flows as well as bp4w, has slightly more aggressive cam profile (but barely enough to notice). They are more readily found compared to a nearly unicorn head that was produced for only 2 years in the miata. They use the same intake and exhaust manifolds.

Build it once, then man up if you're going to talk the talk.

Last month I bought a used 99 head off E-bay for $260 (shipping included). AZMiata or something like that was the seller.

There's also another ebay vendor that has a ton of Miata parts and some heads; based in florida and goes by miata-cabrio

It's more in the $400 shipped range

Prices on some other items like blocks and cranks are rediculous

Thank you, I'll look for him. See if he will have anymore. Currently there isn't any on there.
