[urq] Bad turbo not so bad - head gasket/timing

[Richard Tanimura]

I share your affection for the low end of the K24. I have one on my S2 which
starts to perk around 2200 but really starts to cook around 3300. Very
similar data to yours. I keep thinking what I really want is a K25 - the in
between size that they don't make.

Mike-
you'll be at TDC when there is a sideways "0" in the window of the
bellhousing--gotta look closely.  It should be lined up to the bottom of the
window. Another solution to the filter housing/oil line deal if you go to
K24 is to get oil lines from a 1985 5kt.  1985 only, IIRC.  They bolt right
up to stock 2 filter boss and water cooled turbo.  I got used ones from
Dad's in CA a couple years back. Personally I think the K24 is a great turbo
for the urq - I like the reduced lag of a K24 that 5300 elev encourages on
the K26.  Here in Denver ISTR getting good boost around 2300 +/- with a K24
but not til about 3300 rpm with K26.  YMMV.   Pretty weird about the
turbo-reminds me of something I've seen-- Forgive me if I've told this story
before but it just bugs me....Shortened version:  I have a K24 newly rebuilt
(~3000 mi) that worked perfect at start up - produced good boost, no
abnormal noises.  Once everything warmed up it would start to make a howling
sound and produce no boost.  The impeller spins smooth as butter, virtually
no end to end play.  No visible evidence of any blades hitting the housing.
Weird.  Clearly something is going on internally.. Good luck with your
project.

to some piece of carbon from the chanber or other junk due to head removal,
however there was a definite restriction... this was during the German
trip... however after 20 min drive it freed up and started to work again, it
worked perfectly untill while later when it blew out an oil seal on the
exhaust side due to exhaust restriction....

water pump is possible, BTDT and works quite well, as long as you have
everything aligned and the new head gasket is not way different from the old
one.

covers it.  Oh yeah, your oil cooler won't connect to the new single filter
housing, custom connector is needed.
