Old link to Carl's site which is no longer operational but you can see some of the parts http://www.carldavey.co.uk/product.php?id=2
Someone beat me to it, disregard this.

The only one I've seen done was on one side between the plenum and the runners (making one side of the plenum a bit bigger)

Default Phase 1 EJ25 dohc intake and to a Phase 2 EJ20 sohc

Thank you for offering those adapters.
My project was replacing an EJ 25 DOHC cam Engine with a JDM EJ 20 SOHC.
I thought I was doing really well until I realized that I was dealing with switching engines from Phase 1 to Phase 2. If these adapters fit and work. I will be very happy. And I can continue with my project. How do I order etc?

OP hasn't been on here for 4 years, and original post was 10 years ago

Probably easier to get a local engineering mob to make some for you
