Below is the turbo that came on my car. This my first turbo car other than diesel truck so I really don't have anything to compare it to. I have a carbed 240 w/l28 on the line they are about the same. The car, 240z has a modified 300zx ecu, 420 injectors, external wastegate, forged pistons... The build sheet says good for up to 20lbs of boost but without a wide band I have it set at 12.
My question, it seems to take a while to spool. 1st gear little or no boost 2nd getting some .. 3rd 3000rpm hits boost takes off 4th the same as 3rd nice. 5th lots of fun but cant really drive too much at 100plus mph. So.. is the turbo too big ? will a smaller turbo spool quicker? I thought i fixed the boost leaks but i need to check again. dont have $ for turbo right now but maybe in near future...
I am not sure of the cam thats in it n42 head that has had some work not sure what but it came with a brand new cam that I have sitting in a box :
109degrees LC ?
Int exh
Dur. 280 270
lift 480 480
clear 006 010
open 31 64
close 59 26
I have done some searching but nothing to tell if the cam will add more bottom end >...
Any thoughts are appreciated
Thanks
