on na13b motor? i heard it bolts right up.. specifically where is there too little clearance?

i was thinking of building a hybrid s4 6pi turbo motor out of the car, and im wondering, cuz ive heard that the manifold should bolt straight up..

 

Read the FAQ. Why is this so hard for people to do? It's layed right out for you in the FAQ at the top of the page. It doesn't fit because the 6port lower intake manifold is too large due to the aux ports, if it weren't for that it'd fit just fine. Now there are many ways to get around that (such as I've done) but I'm not going into detail, just read the FAQ and you'll have all the threads you could ever wish for.

 

Or even a little searching...
