My 70 Duster build

It is an awesome project you got there, being a toyota race car owner for long time, my only question is, why that old M series engine and not a 2JZ newer more powerfull and reliable one? not expencive if you use the lexus GE non turbo unit and converted to turbo, i have seen Factory internal 2JZGE converted to turbo in the 600+ WHP range with good reliability for years and years, ohh and a r154 with the marlin crawler internals can stand 1100 WHP on a 2800 lbs. car, i used to have a 1100+ whp 2JZ 79 Celica drag car and trust me the only way to go is with the 2JZ!
