This game has eveything you want you can mixmatch parts head, cams, pistons, rods, everything. You start out buying a car from a used car dealership and you never know what your going to get. Once i go a delsol that was missing a wheel and a sideskirt but under the hood was a 1.8 motor that was in perfect condition then I went back and got another one got it back to my garage and found that it dident even have a motor . The game has a couple glitches, but if you download all the patches there will not be any problems. the picture below is of my 695hp / 467/TQ AWD (1.8block, 2.2crankshaft, 1.5pistons and rods, 2.2cdcv head, 2.0 racing cams, 22LB turbo) delsol just remember every motor is different just like real life
