Carrillo offers TR6 rods, and you can bet they are strong.
www.carrilloind.com
For a higher strength rod than stock, you can detail your
existing rods by polishing
the beam and polishing out the forging marks and smoothing all sharp
edges. This will increase
the strength by a significant amount. Then use a specialty fastener like
ARP rod bolts for
a further increase in strength. This is the budget approach to high
strength rods. It will
be 25-40% stronger than stock. Course a Carrillo rod is probably 80-100%
stronger than stock
without any detailing.
As always, if you are doing something special, you need to get
the parts crack checked
before you start polishing them. No point in spending all that time
detailing them if they are junk
to start with.
The TR6 rods are a forged rod, so they are decent to start with.
However the materials
used are nothing special, just a medium carbon steel, say 1040 steel. A
Carrillo rod will
be a space age alloy that has nearly double the strength of 1040 steel,
(and probably double
the price).
As far as lightening does, yes you can lighten them. It will be
a lot of work,
but you can probably shave off 50 grams or more. They will already be
lighter after you polish them
by a few grams, and they will be stronger. The trick is knowing where to
remove the material.
You can remove any balance pads, if you are careful to match the rod
weights. You can substitute
a cap screw for the stock bolts, or use a 12 point nut rather than the
stock 6 point nut.
There are many options.

Subject: best rods
I would like to know from those who know much more than I ever will,
what
connecting rod is best if you are attempting to build the ultimate
street
driven TR6 engine? FYI, I am supercharging my engine. I am having my
crankshaft lightened considerably. I would like to buy the lightest,
most
durable rod available. Also does anyone know what the stock rod weighs
so
that I may compare it to what is offered. Can I lighten my rods and
expect
them to be durable?
