I just got my hands on a 4 to 2 manifold with dual down pipe. Came from an 86 Jetta 1.8L 8V Karat. Everything looks good. Now I need to know what I need to get to install this in my 92 Jetta 1.8L 8V. Both cars have digifart, the only thing I can tell I'm going to have problems with is the O2 sensor. right now in my 4to1 mani, it is threaded in there. The 4to2 doesn't have that which tells me that I'm going to have to put it in the Cat. Converter right? And if so, which VW converter do I get? Do I have to change the studs for the manifold? gaskets obviously, Can anyone help? Mind you this isn't going to be done until I get my hands on a cam,and so forth, so it won't be until early spring, So a little parts buy here a little there, then spring comes and my car goes ZOOM!

you need: exhaust gaskets (head ot manifold, manifld to dp), flange kit (3 bolts, sealing rings and triangle thing for the flange (dp to cat), 55mm cat from either an a3, a 1.8 16v gti/gli, or a 2.0 16v passat (i got one from tt) it has a hole for the 02 sensor, and is the correct size to bolt onto the dual dp. also if your exhaust is setup for a 50mm cat, you need to get a new centerpipe, or cut it and get a sleeve clamp (NAPA has em) also haveing some spare studs and nuts will probably come in handy.
the cat you need could come on other cars too, or if you can get tot he donor car grab the cat off that. thats all i think.
