IbizaPartyBoy 34 Posted December 30, 2014 Report Share Posted December 30, 2014 Anyone know of any UK cars running one of these variable manifolds of the later US mk4 12v AFP coded VR6?? Thinking of picking one up while in the US in March for my mk3.. Link to post Share on other sites
Swivelonit 119 Posted December 30, 2014 Report Share Posted December 30, 2014 I have a variable manifold in my garage off my MK 4 24valve AUE engine, save yourself some air fare and buy mine. it isn't green though, just bog standard silver. Link to post Share on other sites

Is it the same as 12v then?? I can get a 24v one 2 mins from my house as pal has breakers yard, and so does my dad in London.. possibly just the lower bit different? Link to post Share on other sites
Swivelonit 119 Posted December 30, 2014 Report Share Posted December 30, 2014 I have no idea if it is the same as a 12v, I took mine off when the turbo went on as it was no longer required. Link to post Share on other sites
VR6Pete 1,455 Posted December 30, 2014 Report Share Posted December 30, 2014 Looks like a 24v manifold, I have heard of people who have managed to retro fit them onto a 12v a long time ago, not sure how easy it is though! Link to post Share on other sites
Swivelonit 119 Posted December 30, 2014 Report Share Posted December 30, 2014 I do know that when I ordered my short run intake the 12v and 24v are different, maybe the inlet ports in the head have slightly different spacing? Link to post Share on other sites
daveyboy 897 Posted January 1, 2015 Report Share Posted January 1, 2015 There's only one way to find out mashupmicky and that's to give it a bash and let us all know if it can be done VR6Pete 1 Link to post Share on other sites
Mk3highline 287 Posted January 1, 2015 Report Share Posted January 1, 2015 I think you might have to get the US rocker cover too With this type of manifold on my 24v there is a gain of nearly 40ft lbs torque in the mid rangeAbout 20bhp D11PS and Bealieboy 2 Link to post Share on other sites
IbizaPartyBoy 34 Posted January 10, 2015 Author Report Share Posted January 10, 2015 Cams have to be changed as well apparently ?? lower inlet is the different part, so possibly use the 24v uk top part?? Want US rocker cover anyway.. Link to post Share on other sites
RBPE 198 Posted February 2, 2015 Report Share Posted February 2, 2015 It's port matching that would be the problem - drop a thread on Vortex and they will be able to tell you. VW did make the 24v engine at the same time as the 12v though so I would have thought the easiest thing in terms of manufacturing would be to make plastic ones at the same time as their 24v VRIMS. By the way, the only reason that the 12v didn't have one is that the money men couldn't quantify the cost and so Schrick bought the rights on the 12v and VW brought them out on the mk4's, which, in the US had 12 and 24v - but we got 4motion Link to post Share on other sites
