I finally got a few spare hours to attack my 3B project, which
now, in the face of overwhelming advice, is a "refreshening" rather
than a rebuild. I dismantled the starboard side of the engine last night,
generating the following questions:
1) What should I divine from seeing so much carbon built
up around the exhaust ports? In the pre-electronics, carburated age in
which I learned about cars, I'd simply say that this car simply had really light
use and needed a couple stoplight drag races... There's gotta be what, 1mm or so
of carbon caked up in there...
2) That exhaust manifold really does appear to be an
sub-optimal design. Anyone with experience upgrading to the RS2 piece (or
IA equivelant) I saw in Euro Car? Any benefit to using it without
concurrently upgrading turbo? The manifold pictured in EC has four studs
per outlet, the stock manifold has three. What are my options
here?
3) I figure I'll replace all the studs, along with all
the other fasteners on the engine. Some look pretty grungy and I'd rather
not break any (more) off. Any advice about using heat on a steel stud
screwed into an aluminium block?
4) Folks who've done the 3B-into-CQ swap have found that
the oil filter interferes with the AC compressor. Solutions have been: a)
remote locate the oil filter; b) swap compressor and alternator locations.
Anyone know whether a third solution might be use the S2 Oil filter bracket
assembly? It's a different part number from the US 200tq 3B, but looks the
same on the fiche.
5) I've heard people on the list complain about melting
through the rubber hose which runs behind the heatshield from the turbo to the
ISV. Mine is metal, except for the final 3". Perhaps a change
within the model year?
As usual, TIA,
