It has been way too long since I have touched base with the list; I hope that
you guys (and gals) will be interested in the major engine modifications that
I have just now undertaken with an Oregon TR6 engine specialist, Precision
Research Industries. I learned of them via one of the member's comments
several
months ago, and only know have managed to allocate funds for the project. I
have chosen to do a full performance modification with the usual head work, JE
pistons, Chrome Moly connecting rods, iron Nitride crankshaft, roller rockers
(1,65:1) moderate cam, titanium valves,crank case venting kit, K&N filters,
hot tank cleaning, blend porting,new oil and water pumps, new main and thrust
bearings, light tubular push rods, lightened flywheel, all new seals, paint,
but what excites me the most is the Keihin induction system that this shop
specializes in installing on the TR6 engine. For those of you not familiar
with
this system, it employs four carbs commonly used on racing motorcycles.
P.R.I.'s owner, Christopher Cancelli, is a long time cycle enthusiast and
racer, and
has found that these carbs are a natural for the engine found in the TR6 and
the Spitfire.
I will have to relocate my stock air conditioning compressor when the
engine is finished and shipped back to me for reinstallation in approximately
90
days (carb clearence problems), but I do not anticipate any other
difficulties...Total cost for this project will be about (hang on to your
shorts)
$11,000, as I opted for the most thorough and expensive modification package
PRI
offers. You could go with a far less expensive option, like the stage II
($7300)or stage I($3600) package. The carbs go for about $2500 if you only
want to
go with these.
I will keep you guys posted as the work goes on, as Chris is taking
photos as does the work. As some of you may remember, my engine currently has
twin SUs and 9:5.1 compression, has excellent low end punch, but I was ready
for
something a little original..perhaps a bit extreme I guess. I am an attorney,
with a good practice, and am fortunate to be able to do this project at age
56. We baby boomers tend to pull out all the stops as we look for ways to
distract us from the continuing AARP mailings and retirement lurking in the
distance. Till later.
