Hi Guys,
Just wondering if anyone on this forum has any idea about mods on a 21r engine. Do 18r heads fit, are there alternate pistons. Has anyone built a 21R before and what did they use.
I'm building it into a race engine for my corolla. I don't want to go down the 4AGE road as i want to run a 2 litre class and the car is already fitted with this engine
Cheers Josh
