I dont mean to wreck your dreams of a 600bhp twin turbo suzuki escudo, but the vitara drive train will not handle the power!! It will shear the front an rear axle's and shatter diff internals, suzuki drive train ant very strong, not to mention the front diff is made of cast alloy

.
I have just joined this forum to get information/help with my single turbo (tdo4) h25a V6 vitara engine build..
Look into the KL mazda V6 series engine's as a transplant maybe ?
