Question to you dieseleros: Putting (I hope) the finishing touches to my
'83 1.6NA - to - 1.9 AAZ TD. I picked up a '92 Dodge Caravan airbox at the
wreckers. Diameter of inlets (2.5") matches inlet to the turbo, but is
smaller than the "bell" on the airbox connector tube that came with my
motor. I noticed that after hooking up the airbox my warm idle has gone up
significantly. Can reducing the end diameter of the inlet tract increase
idle speed? Any other comments appreciated.
Side comment re: mufflers: my local muffler guy did a nice clean job
putting in a thru-flow muffler. Because he couldn't get one 25" long (like
the original) he had to fabricate the right hand bracket to jog over to the
stock mount. The bends from the header to the muffler were tough - he spent
5 hours on it. So not cheap! But a nice clean install. BTW, I had him but
an O2 sensor boss on the pipe as close to the header as I could. I can put
an exhaust temp monitor on there if I want.
Thanks for comments, David
