Prelude intake update

 

So here we are again, my intake. <WTF> This is the intake on my car. This is the upper plenum from an h22a1! not my 99 sh.

it looks totally different. on the one on the car there is a spring valve that says "up" on the picture above. this plenum does not have one at all. just a little vacuum connection <under black throttle cable catcher on right>

 

 Also, notice, that there are NO NIPPLES for a vacuum on the right hand side of the manifold.

No nipples for a vacuum connection on the right hand side of the upper intake plenum.

Here is the mapping for a 99 prelude SH. now I understand why i am confused and cant figure out why its not running correctly and why none of these maps make any fucking sense.

This is the intake vacuum map for a h22a1/h23a1 (prelude 92-96)If you look at this one, the nipples are there on the right hand side of the intake. So, now, all i have to do, is remove the upper plenum, reseal it, and remove the IAB, rerun the vacuums, and take off the TB/cable. Not too bad considering how much work it was to remove the whole intake itself. at least this I can get to. but it is going to have to wait until i have the gasket. Hopefully it will be cheap. I cant see that being super expensive, but well see.

Hope this helps someone else out there.
