the c20 xe and the c20 let in a corsa are a lot of fun and a pretty easy conversion to do but tractions a no no you get none wet or dry unless you drive like a granny, the let loom follows the same route as it would standard or with an xe, if you going for it is also advise an uprated fuel pump and uprated high pressure fuel lines, as for rapairs and reliablility there all right the xes the way to go for hassle free 2.0 as spare engines are available all over the place but the lets a bit special but does use the same block and head as the xe except for a oil return on the block which is blanked on the xe
