Bore out the holes on an S4 turbo manifold and it should mount up. Or you could take your 12A flange and weld two pipes to it and weld those to the S4 manifold. I have seen both done before.

Eau Claire, Michigan????

Someone here on the forum made/sold me an adapter manifold. It was basically a 12a exhaust flange welded 2 inches apart and angled upwards to a 13b exhaust flange. I think I got i for around 60 bucks shipped.

I'll try and dig up tomorrow morning and get you some pictures if you want

Buy the 12A flange and pre bend pipes and weld them to fit where you desire. below is a link to ebay as an exaple from a 13b. No need for the waste gate pipe if you are using a turbo II with the pre build waste gate in it.

so now if i were to bore out these holes as said above it should fit a 12a right?

I think you miss understood, The link is an example of the finish product. The flange to the engine can be purchase at racingbeat .com, a 12a flange wish need no modifications to it, and the pipes you can purchase from them as well.

oops sorry for the misreading.. i get all excited and dislexic (sp) at times..

mikewoodkozar

on a stock 2nd gen turbo manifold, yes you can elongate the holes and it will bolt up to a 12A

yetterben

you can tjust bolt up the stock s4 mani to the stock 12a block with the stock intake the turbo will hit the intake

This is from a 13b project but no the less in the right direction. I have heard i should try to angle the turbo up and forward a little. any reason why???
