I can second the quality control for Venolia pistons.=C2=A0 Several years a=
go, we
did a group buy of several sets of TR-4 pistons from Venolia.=C2=A0 I weigh=
ed
them when they got in, and matched them to sets based on weight.=C2=A0 Even
over the five sets (I think it was five, anyway), they were all very close. 
By hand picking them, though, we were able to get all sets almost spot on.

I weighed all my Venolias=C2=A0when I got them new and they were all dead

I have a more conservative redline in the TR6, 6000, but it will easily 
go beyond that. 
Happy New Year everyone.

I've had a set of Venolia Pistons in my race GT6 for probably eight 
years. Just measured the skirt dimension against an unused spare- =C2=A0 
0.6/1,000 of wear, max. =C2=A0They'll be going back in the engine again 
with new rings. My recollection is they are about $75 each. 
My routine redline is 7,000 rpm.

I will say I admit to having general misgivings about anything made in 
China but that=E2=80=99s based on experience. Why risk your reputation and 
the expense of a total build by using cheap pistons. It=E2=80=99s a false 
economy. I dreaded every time the phone rang for a month after 
delivering the car, but in this instance they seemingly met the 
requirement. It takes years to build a reputation but it can be lost in 
mere minutes.

County pistons may work for street car applications but are a risky 
choice for the rigors of racing. Spinning a bearing indicates either 
poor clearances or an oiling deficiency. A proper rebuild should check 
and correct only everything! Don=E2=80=99t assume the one problem you find =
is 
the only problem. Shortcuts predictably end up in expensive disaster. 
=C2=A0
I=E2=80=99ll step off the soap box now!

Choose wisely!
