hi there basically my engine was built to the same spec as a rally engine and the turbo the same. its an md240. ive searched this and it should flow enough for 450hp but the back housing externally is the same as a t28 escos! the engines are obviously built for quick spool up time but no top end power?? as it was on full boost (36psi) by3000 rpm. i want to use it for drag racing i hope



it high comp, think 9.1 : 1, massive custom cams, inlet more than exhaust, isky springs, lots of head work- massive inlet ports, think thats all you need to know. what spec turbo should i go for as i want to change.
