Ok so im kinda new at this..i've been doing some research on the GM supercharger. Im lookin in on getting one but im not sure if i should rebuild the motor before putting it on. I have a 2001 cavalier Z24. 113000 miles on it. i have taken care of the car for the past 3 years and have i got the car at 80000 miles... can anyone give me info on wheather i should bore out the cylinders get new pistons, knife edge the crank, get dished pistons for it for lower compresion,do a secret cam swap, and maybe port and polish the head. Im not sure if i will get more performance out of my engine with the supercharger on it with all those mods.(for the price of doing all those things).or if my motor will hold up with a supercharger on it now that its stock.
I have heard people saying that they put the supercharger on there motor being all stock..except for the exhaust and things like that..i know the basics of what i need to do but im just not sure if i need to do a complete engine rebuild of the bottom half?
anyway thanks for taking the time to read this and if anyone has any info on it i would surely appreciate it.
it's not necessary to rebuild the engine for supercharging a motor how ever more performance parts will allow you to run a larger amount of boost which will produce larger dyno #'s
The GM kit is designed to bolt right up to a stock motor with no additional work required. The kit comes with new injectors and plugs which is all you really need. Obviously, to get the most out of it you will want to do supporting mods but stock will work fine.
ok thanks for all your help guys!
how much boost could i possibly run on it without damaging anything?
Since the LD9 is such an unpredictable POS it's hard to say. I had one motor that had something around 50k boosted miles and was still running strong but failed for other reasons. Then I got a brand new motor from GM which popped with 10k on it.
if you boost it with the kit you will get between 5 and 8 psi. if you don't f@ck around until you have other mods done it will be fine. just leave at those settings until other modifications can be done
what other supportings mods would you guys recommend?
the key to any boosted application is fuel. as long as you have enough fuel you won't hit detonation. if you can get enough fuel in the chamber the only thing i would worry about would be head gaskets and connecting rods. but if your going to replace rods you might as well do the whole bottom end
