is there such a thing as cosworth forged pistons? and turbo rods?

cosworth have made pistons for the A series, ( and most other engine).

turbo rods are just normal generic A+ rods.

the A+ "Turbo" rods are a specific rod,,, not the same as std rods

they "look" like std A+ rods but are slightly different , easy identified because they have their part number goes right the way up the whole length of the rod ... & are made of a slightly better material than the std rod

No offence intended here but--> anyone writing a book about minis 30 years ago may not have experienced such worn or stuffed-with components as we are finding these days.

You should put your heart & soul into everything you do.

is the a+ rod the one with the massive weight hanging off the big end cap?

do you have a p/n for an a+ turbo rod? and a p/n for a normal a+ rod?

No, the heavy one with lumps is the last of the A series (eg late Morris 1100S, Morris 1300 auto, Mini 1275LS)
Std A+ rods are not bad for most purposes. They are lighter than both the 1100S lumpy ones and Cooper S rods.
