LQ4 or LQ9

What's better for boost? I have a lq4 in my garage just want to do this right. I hear these motors stock w a Turbo will push out some major HP numbers but only time will tell

both are basically the same, the lower compression will let you run a lil more boost on pump, but the higher compression of the lq9 will help spool the turbo just a lil faster

either one will work lol

The LQ9 has better rods unless the LQ4 is a 05' newer engine.

the LQ4 i have is from an 03 Denali i was told. Well both should work well. I hear that even a stock 6.0 will be nasty with a turbo that the bottom ends hold up really well.
