I'm building up an LQ4 and I need some advice. I have had the block prepped and ready, bought my forged internals which consisted of a 4" eagle crank, 6.125 eagle rods and JE pistons( need help here ). Now this is going to be a daily driven nitrous motor and I plan on running L92s and an LS3 intake. I have an MS3 cam for it but I was told I should to with a different cam. That's where I need help. I plan on running a 150 shot of nitrous.

 

Also, can I safely run 11:1 compression ratio? I have been told not to run higher than 10.5:1 but I think that's false. We have a max of 91 octane at the pump.

 

Cam selection completly depends on your power goals. An MS3 would work fine wth your setup but Im certain that a custom grind would better suit your needs.

Also, a nitrous cam may suit you but if you intend on driving the car on the street N/A more than Spraying N20, you should just consider N/A Camshafts.

 

Ok, The pistons I got with this rotating assembly are JE Forged pistons with a -26cc dish, which is like 9.8:1 on 59cc combustion chamber, How possible is it going to be to make these work for 2-3 months until I can go forced induction? I figure with 2500-3k I can get a decent forced induction setup. Or should I sell or trade the pistons for some flat tops with valve reliefs and just run nitrous?

 

im running a 11;8;1 compression on my ls3/lq9 stroker with 64cc ls3 heads, -2 diamond pistons...custom cam is alwayz the best way to go especially if ur gonna run the ls3/76 heads

 

Running that CR on Pump 91 octane gas?

 

MS3 and MS4 cams love the dope the 150 shot wont be a big deal for a daily driver with the ms3............. i have a ms4 ,.......and love it
