Joao - look at Kastner's books on tuning GT6s and talk to Ted Schmacher about
engine tuning. It only takes money to get horsepower and shed weight.

Subject: [TR] GT6 engine
Hi!
As some of you may know, I am building a GT6 chassis with a Spitfire body.
I need some wisdom on the engine.
I am seeking something like 120 to 130 hp from the 2.0 liter, any suggestions
on cam, head work, carbs and exhaust?
Also, I understand the tr6 has the same engine but longer stroke, but this will
require an oil pan 'mod'. Is this extensive? Also, is the 2.5's greater torque
worth the loss in revability?
Finally, I understand the 6 is heavier than the 4, negatively affecting
handling. I am not planning on modifying how it is mounted like Mr. Tegler has,
as I am not that skilled, but is there something to be gained by using an
aluminum water pump body, front and rear engine plates and radiator?
Would the aluminum parts being bolted to the cast iron engine cause corrosion
issues?
Oh, and is the stock oil pump ok? I heard it's the same as the Spit's. Also,
are the stories about using an extra hose to route oil to the head for the
rockers helping true? Would that Rob oil from the main bearings?
My purpose is to have a fun road car that is tractable and can occasionally be
taken to the track for amateur fun events.
Sorry for the long post.
Take care,
Joao
