Ive had 2 wire rung HT racing engines in 2wd Cars, both on 205 blocks , both were fine and ran a pinto or std cos head gasket up to 2.0bar . As soon as i added a T4 tho , all fkin hell let loose , the wire blew out the side of the block , destroyed the head and dropped valves into pistons , big mess ! Long studs and Coopers rings or a WRC gasket now !
