Thanks a lot Scott. I knew that I will hear from you. I knew I
will receive lots of answers from you.
I already found that the water pump is no good. I think I will
use 1.9 cooling system. So I will not use the bad pump anyway.
Glad to hear that I can use the 1.9 exhaust. But if I come across
a 2.1 exhaust system I will use it. I like the sound of the 2.1
exhaust. The sound of 1.9 exhaust is not very attractive to me.
They are always regarded as loud noise.
Yeah, I see that metal pipe end pointing up from the plenum
box. OK, I will deal with that. I will use the 1.9 cooling system as
I already have it on my 1.9.
Oh, I think the cylinder heads are OEM. Thay have VW part number and
logo on them. I do not see the AMC word on them. I guess this is a
positive sign. Of course I will have to see inside to see if there is
any cracks or bad pitting. Since the water pump is bad the heads
may have been toast. I will have to open it up to see. Hope they are
rebuildable still.
Well, the difficult part is the bottom block. I have not worked on
any short block project before. I will have to figure out if the
block is usable or not at all as Allan seemed to suggest.
One more question. Does 2.1 give more than just a kick in terms of more power? My 1.9 has 82 HP on the spec. 2.1 seems to have 105 or more?
I think anything over 100 is going to be significantly better than 80+.
Thanks again, Scott.
David
