Hi all, My engine is a 4AGZE from an aw11 MR2 1986. I am building the engine up for more power and ultimately want to turbo after getting bored with the supercharger. I would be very happy with 200kw at flywheel with increase supercharger boost and effective ic. Other mods are: ARP head studs, port and polish, TRD head gasket, Kelford 193T cams. I have new Hastings piston rings and need to gap which got me thinking of the following questions. 1. What power can the 4agze low comp 8:1 pistons and rods take? Crank is the 42mm and a 7 rib block. 2. What would be the next week points in the engine? 2. Assuming that is my max power for the build, would anyone be able to guess approximately what boost pressure would get that power? Thanks Al
