Curious if anyone ever made or had one fabricated? Reading through performance posts from back in the day and all things always ended with the intake manifold was the most restrictive part on the 2v and to get serious power you would need to have one made.

Anyone ever do it? Looking on a couple sites that do it looks like $2,500-3k job

If not does porting the stock manifold do anything?

 

I'd like to know about this too.
