My mods are in signature. I have a police car lo5 which has lt1 bottom end in it supposedly and 9.6:1 compression. I have less than 2k on the motor and its carbed. Before I run n2o I am for sure replacing the intake pump. My intank pump is a stock lo3 170hp pump. I might go with the 255 walbro just so i have the fuel if i need it.

If your wondering why my carbed car has a intank pump its because I swapped from TBI

Im running a mallory fuel pressure regulator at 5psi right now. If I get n2o Ill upgrade the fuel pump and ill be running a plate wet system of course.

BTW I will also have a MSD 6al box before so Ill have some type of rev limiter just in case something bad happens.

::edit:: I have hypertunetic pistons and lt1/lt4 rods

 

100

 

with cast pistons, your prolly gonna want to keep it under 150.

BWT, what kind of rods/crank do you have?

 

I have hypertunetic (cast?) pistons. I lost my paper on my motor but I know it has lt1/lt4 rods...not sure about the crank.

 

cast/hypertunetic are same thing. if youve got LT1 rods, i KNOW they are hardend steel rods which are pretty good. i THINK (not sure) that LT4 rods are forged alum. as far as the crank, as long as its a good steel crank you should be ok.
