So i've got almost everything to replace the 1.7 with a 1.9 into my vanagon. Unfortunely because the 1.9 originally was an ADG industrial motor it had an exhaust manifold with a tiny outlet-1 5/16" .Since it's getting a larger IP ,the original one was 8mm , i would think that manifold will choke the output. If i have to i will use the exhaust from my 1.7 but i think i need something bigger-at least 2" . The problem is that the outlet has to be near 3&4 and point towards the rear [actually to the front of the truck]. I was wondering if there is a hi-po gasser manifold for like a fox or quantum that would fit.
