Re[2]: Rebuil and custom Exaust! In CA? And cooler oil...

Wilson,
Ya know, you can buy merged header systems for the T3 and they allow you to 
keep your heat exchangers.

As for the secondary oil cooler...  Gene Berg was a very experienced VW man 
and helped the VW community with his knowledge, however, this doesn't make 
him a VW-God (even the VW engineers made mistakes).  I see Porsche 911 and 
914 (these contain a (slightly better) T4 engine) racers that have bigger 
engines and they use a bigger and/or a secondary oil cooler -- it's just a 
given.  More horsepower, more heat build up.  Just changing the compression 
ratio, as Berg says should be done in his manuals, to satisfy the heat 
problem isn't good enough; suppose you want the higher compression (for 
whatever reason)?

If you want to go with a secondary oil cooler make sure that you have a 
thermostat hooked up so no oil will flow to the secondary unless it's hot 
enough to warrant being cooled (Porsche 911/914 catalogs have ones that 
don't operate until the temp >170 degrees F).  Also make sure the secondary 
has good air flow going through and past it.  Try to make the secondary 
like the stock unit (radiator style) as will cool better since the standard 
after-market tube-and-fin style isn't as effective.

Of course, the most important thing to remember is make sure your entire 
engine cooling system is in perfect condition!

Hey Steve - Your engine sounds sweet. I've been wondering if I should switch
over to a similar set-up. One question (I'll also post this on the T3 list
for others to chime in) - how well do oil-coolers work? I seem to recall a
Berg article saying that they did very little to cool the oil and added lots
of possible problems. I have seen a nice-looking setup on a conv.super (lot's
of cooling problems) where the oil was only routed thru the cooler if it
reached 200+ degrees.
I'd like to take you up on your blueprint offer (a copy), thanks and good
luck!
Oh, Ps- how did you decide on tose carbs? Just wondering.

Dear peoples,

                Well i just finally finished rebuilding my 1776cc. It kicks
ass. Actually its not in a vehicle yet. But anyway this is what i did. Took
it all apart and soaked all the pats in a giant bucket of degreaser for a
week. Then i categorized and seperated the parts. That took me a few days.
Then i cleaned and polished a  the parts. Then put it together and Duall
Webbers on. While all the parts were in the degreaser i was building my
exaust. First i got 4 J-tubes from rocky mountain and 2 stingers. So when the
engine was rebuilt i tweeked the 4 J-tubes so they could come out as headers
then i merged the ends and put the stingers on. If you want a some what of a
blueprint just e-mail me and i will send you a copy. So now its a smoged and
ready to be put in my sb. It has a most perfect sound too. Also i added an
extra oil pan/resivoir and im getting an auxillary oil cooler too!!
