Ive told you where to go for a manifold dude the ones you have just listed arent up to much.
There are plenty of SR20VE's in the UK that have been running with no issues for ages now. Kurts, DMSteve's, RagT's, and Wezz's/Dan's...
Get a 20VE with your 16ve cams in then get a GTi ecu fitted with Nistune, put a SR20VE map with N1's on it and your laughing.... someone will then be able to map it very easily for you.
