    Hi M8,
    The general concensus is as follows:-

    Keep the OEDV in the system and fit an AM one as near to the TB as possible.

    Most members have gone for the Collins as have I.

    Have you by-passed the rear BCS?
    If she's not sticking her fingernails into the roof lining and digging her stilettos into the dash then you ain't going fast enough!!!

    i have a baileys DV26D on my Coupe turbo, i am assuming you have a Z20let lump aswell. I plumbed it into rear bcs(boost control solenoid) first. This gave me turbo chatter. I was advised to put a halford "non retun valve" into the tubing from the oe dumpvalve to see if this stoppd the chatter. It didnt! So when i went to billing i gave my car to dave (buckle) and ben (bertone ben) they quite simply plumbed it into the FPR (fuel pressure regulator) and left the OE dumpvalve working and it runs pefect now. not had any problems since then. Bu from what i gather you can have same lump as someone but the specific engine reacts differently to how its plumbed in.
    For free hugs PM me.

    For sex, pm cabriomatt.
