For L5 4 cyl or 3cyl?

If 3 cylinder me think can because L5 3cyl (code EF-RL) have the same bore size with L2 (code EF-JL) i.e. it got 68mm bore and 60.5mm stroke

and... you loose 0.5mm of compression ratio if using L2 piston (8 vs 8.5)

If 4 cylinder (code JB-JL), you have to rebore a lot because it has 61mm bore and 56.4mm stroke

If ur engine is a L5 3 cylinder, my advice is to just rebore your L2 sleeve and install a Kelisa (1.0cc) piston. although its a low compression piston, but it can withstand boost up to 1.8 bar with no management and the engine last quite long until the gearbox kaput and the kancil is now total lost due to accident..
