Lowers are different so you can't bolt an 01 UIM to a 99 LIM, but you can bolt an 01 LIM to a 99 head.

 

exactly wut i needed to hear. thanks a bunch! this will make trying to track a LIM wayyyy easier and prob cheaper.

 

So what is the best intake manifold for a (350 whp turbo) with a 99 head?

 

blox or skunk2 manifold.....edelbrock victor x is probably 'best' of the honda ones for 400+ but below that you're probably just giving up a good bit of low end powa

 

victor X is designed for 10,000RPM, it's not the ideal choice for our motors.

I'd choose the performer X over it.


IIRC blox is a rip of the skunk2, which is a rip of the ITR oem manifold.

 

im curious. why would you dare think of putting honda products on the prestigious miata?
It would be like a betrayal of the philosphy behind the mazda roadster. parumph.

 

I'm curious. What's a parumph?

 

Apparently;

 

He's oh so close to 15 posts, though...

 

Miatas are not prestigious. They are a shell. It's the go-fast parts that make them fun. Otherwise, they are just a chick car with 90 horseys.

 

I'm about to build one of these, but I need the flange.

I know I saw a CAD, or solidworks drawing on here a while back, but cant seem to find it.
Can somebody find it please. It would be greatly appreciated.

 

Yellow, which mani you going with?

 

I'm chiming in again to say that I haven't completely forgotten about installing this bad boy, it just was moved to the back burner. Had a lot of other things going on. But today I ordered some more things I need to make this happen, which is good. Right?

I ordered a 3" --> 2.5" reducing coupler so I can use my existing 2.5" charge piping. Since I currently have an obsolete inside-mount WI nozzle drilled into the existing 2.5" elbow, I went to alcohol-injection.com and ordered 4 .75 GPH nozzles, line, new check valve, and 3 splitters... so I'm plumbing the WI into the mani now, for better or worse.

So now I need to determine the optimal distance up the runners for the nozzles. I also need to learn myself some timing theory.. because if this mani is going to necessitate a spark tune change I guess I need to budget for some dyno time. On top of that, I need to wire up the Honda MAP and change whatever needs changing inside the MS, and calibrate the MAP once in. Jeez...

This had better be worth it.

 

If you went aware, the Honda map is only a 1.7 bar.
You can get bigger ones that fit in the stock Honda throttle, "Omni" MAP sensors are popular.

 

I'm an idiot, I meant the TPS. Dunno why I typed MAP instead. Derp.

 

my turn

 

Please post a finished pic

 

My motor is still at the shop getting rebuilt- that's my biggest hold up right now to getting everything finished, but I will definitely document the flange conversion and all that

 

I'm going to post a few more pics than I would otherwise normally do since there are a number of people wondering about this. Hopefully between aaronc7 and I this shoould be pretty well documented.

Here is the manifold I bought.It is a Skunk2 for a B18C1.



Here is the Throttle Body I bought to go with it since Skunk2 is running a sweet deal off their website.



Here they are together.




Since I got the 74mm TB I will have to do a little port work.



Here is the flange I bought from ftjandra (not sure if he has more or not.)
This thing is sweet, and looks like there is a lot of time spent on designing it.
It is made out of 6061 aluminum.



On the manifold.

 

Nice!!! If I can find a reasonably priced flange by itself, I will go that route, rather than dealing with hacking up my stocker...but they seem hard to come by and/or expensive.
