Where can I find a 8 port vacuum manifold block for my 930 ITB engine setup
I am currently looking for an 8 to 10-port vacuum manifold block for my rebuilt 930 engine with ITB to connect with my brake booster, etc. However, I mostly am able to find 6-port configurations online. Is there anywhere that sells vacuum blocks in 8 to 10 port that fit my purposes? Many thanks in advance for the assistances.

You may want to consider contacting a specialized automotive parts supplier or a manufacturer that specializes in vacuum manifold blocks. They may be able to custom-make a manifold block with the number of ports and specifications you need to fit your specific engine and configuration. Alternatively, you can also check with performance or racing shops that specialize in ITB setups for custom solutions.

If you are getting this manifold in the hopes of tuning using MAP instead of Alpha-N, you may want to go with a bigger manifold that will dampen the pulses and provide a more accurate MAP. Check with your tuner...

^^^^^ Yes, we have used many different sizes, most we built. The smallest was slightly bigger than these. But in all cases we were able to get a stable signal.
We will be making our own for the 2 ITB motors on the go currently and will move up in volume to eliminate any risk. Cheers
