zero 1162 Report post Posted March 31, 2021 Stock internals will take up to 13psi before you need to start looking at aftermarket pistons. 13psi proboably equates to around 500-600hp. There are four different intake manifolds - you want the earliest one with the trumpets. For throttlebody use the one from the n62b48, its 3mm bigger than the biggest m62 one. You will need to port match the intake manifold to it but thats easy Quote Share this post Link to post Share on other sites

zero 1162 Report post Posted March 31, 2021 (edited) Itbs make a great noise, but a very low bang for the buck, and can actually lose power if done wrong. Unless you have a set of s62 itb's lying around, or money is no object, I wouldn't recommend it. If money is no object these are good; https://racehead.com.au/product/bmw_m60_m62_v8_complete_itb_kit_open_trumpetpet/ Biggest gains you can get on this engine is good headers, and bigger cams. Neither is cheap Edited March 31, 2021 by zero 1 Quote Share this post Link to post Share on other sites
