An internet search has not turned up really small velocity stacks for my intake project, maybe someone on HT knows of a source. They need to start at ~30mm and open up to about 45mm while staying ~35mm tall.

Back story: I am building a custom intake manifold for my 1987 CRX Si. The engine is in the EW family of pre D series engines and there is no support for these engines in the aftermarket. No, I do not want to "just do a swap."

The intake on the fuel injected EW engine is actuall two parts bolted together. The plenum is seperate from the runners. I plan to leave the runners and create my own plenum. Inside the plenum, at the throat of each runner, will be these small velocity stacks.

Please email me if you know of a source for small velocity stacks.

Rossmachineracing.com ? I don't know the sizes of theirs, but they are for intake manifolds

 

just do a swap.
Sorry, I couldn't help it.

Cut up some baseball bats and weld a ring on top. Boom, I rule.

 

Have a plug done in a lathe and use a hydralic press to make your own out of pipes.

Or do above to get cones. Make solid rod cirkles and weld to the cones and mechine/sand everything smoth.

I've ordered from Velocity of Sound. Price seemed high, shipping took 5 weeks. Parts were BEAUTIFUL.

Beware that while the material is high quality they're pretty thin. Totally weldable but requires a deft hand on the TIG.
