Bigger Is Better Posted March 30, 2007 Report Posted March 30, 2007 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 Quote
anastasios Posted March 30, 2007 Report Posted March 30, 2007 I'm pretty sure u can use an 18r head, ive reasearched this before try google Quote
Des Posted March 30, 2007 Report Posted March 30, 2007 18rgu or 18rgeu is a 2.0litre twincam, they go pretty good stock and would suit a racer with some mods. Quote
