hi,
yes.....you can use the 1.9 exhaust system..........either exhaust system,
1.9 or 2.1 will bolt up to either engine.
I've done it both ways.
the 2.1 exhaust is better build and has a bigger muffler......
if I had both on hand, I'd use the 2.1 exhaust for sure.
The mounting and support system is 5 times better than what the 1.9 uses.
if you didn't get the aluminum rear engine mounting bracket for the 2.1
......which has bolt holes for the 2.1 exhaust brackets..........two nice
solid ones........you should have those parts too.
yes, you can use the 1.9 AFM on it.
actually...........you sort of have to use the 1.9 AFM and air filter
box............since the main coolant hoses by the firewall in the throttle
body area stick out right where they AFM and air box go.
But you can keep the larger 2.1 intake runners, plenum box, and throttle
body ........those are 'bigger' and you'd want them on there.
Your 1.9 intake boot will fit right on the throttle body too......how
convenient !
- pretty sure.
oh, one slight mod to the plenum box............where a little metal tube
turns 90 degrees and points straight up......
you won't to cut part of that off so the 1.9 auxiliary air valve and hoses
can connect as before.
use your 1.9 distributor and igniter with your 1.9 fuel injection
system...............I just did that and the van just rips.
cooling system wise.....need to convert the 2.1 to 1.9 cooling system.
( or have a whole slew of plastic cooling system parts to convert your 1.9
van to 2.1 cooling system.........I did that on my 85 Wolfsburg
Weekender...........I don't like putting in plastic t-stat housing, plastic
water distributor etc............but you can keep the oil cooler on the 2.1
that way . )
I haven't done it, but you could keep the oil cooler on the 2.1 and figure
out how to interface it with the 1.9 cooling system.
Need the 1.9 water pump on of course, if running the 1.9 cooling system.
but 'all parts' swap over between the two long blocks.
one of these days I might try incorporating the electronic air idle valve
into the 1.9 fuel system.........
there are only a few inputs to the electronic control box for the 2.1 idle
valve........and it is a steadier idle than what the 1.9 delivers usually.
have fun !
if anyone else wants to buy a rebuildable block........
either 1.9 or 2.1..........I got 'em, and will sell.
located in Southern Oregon.
