I answer your question of LM900 turbos (efr 6758) rather than the bigger 7163's
quicker spool... and an LM20 deserves to be driven on track so i feel the smaller turbos will give greater trackability
It’s the 3.8, would have liked the stroker version with the 7163’s but settled for the 6758’s with manifold kit. It’s more than enough for road use and would be perfect on track if I ever was to take it
