Probably recirc as it comes with one. Do you have any problems with yours? You may have stalling issues with bov/dump valve. Stock one, if its metal, should be all you need really, unless you are highly modded.
Thats how it is on evo 8 anyway, ppl change to standard metal one from evo 9 if they have plastic one.
I thought that. Thanks. There is a blitz dump valve on it. It's not recirc as one end has a bung in it. It's knackered and has a lot of leaking hence reason I'm looking for a replacement. Just wanted advice on what's best it's only 330 Bhp
I've been looking at a forge Motorsport alloy Splitter Dump Valve. Can be used as purely recirc and/or recirc plus atmospheric together. Has any one had any problems with these. Camskill are doing them for 130 quid
