Making Smaller Wrist pin bushings for GM 6"rods
Posted: Fri May 29, 2009 12:30 am
Has anyone tried to get pin bushings made with a small ID.
I want to use a GM 6" rod with a Honda journal size as a sudstitute for a Nissan 6.003 rod for use in an "L"-series 4 cylinder race application.
My thought is to machine the Nissan crank to Honda size and use a piston guided rod set up Because the big end is a bit narrower about .050" than the nissan rod thus keeping the rod centered over the oil holes.
The stock rods work and are sized correctly to fit the crank but real hard to find.
The hard part is to find a pin bushing that will fit say a scat rod with the
300zx wrist pin ID
That said I approached them about the pin bushing sizing and they are not willing to do it
If anyone has any ideas on who or where I could get them it will be a big help,
As the rod must be similar to a stock type rod in design but as a sort of spec rod Scat is easy to get here and cost effective if bought in sets they will service 2 engines.
Thanks again,
