need help which throttle body to use for LQ-9 6.0

[petey62782]

i ordered a brand new LQ-9 6.0 it comes with a drive by wire throttle body my truck is cable driven,i want to put a new throttle body in but not sure which to go with or what size . i was thinking either 80mm,85mm or a 90mm. ive seen bbk and edelbrock make nice throttle bodies just not sure which size to go with.also does anyone know what the stock size of the throttle body is on the LQ-9. i would like to keep the stock size unless someone can offer a reason not to. very grateful for all the help i can get on this.thanx

you need to get a TBSS intake so you can put a 90mm TB on there. The 6L engine needs more air for more power. If you have a cable TB, get a cable type Nick Williams 90mm TB and get a bracket for the cable. You'll basically have an LS2 cast iron engine, then.
