Okay, my overall gameplan is to go supercharger for my gsr (I am going to make it an autocross car). I'm pretty much done with the suspension and am going to start on drivetrain (LSD, short throw, light wheels, tires, etc.) but I need some info. If I go with a 3" catback before I get around to the forced induction, will I lose a substantial amount of horsepower due to stagnation of the exhaust gasses or will it increase?

Oh and if anyone happens to know what kind of lubrication can be safely used on the bushings of an ingalls front camber kit to stop the squeakies, that would be great info also. Thanks!

i would say 2.5 would be sufficent for your plans.

You will probably gain some peak horsepower, but overall it will have a detrimental effect on your low and midrange output. I would hold off installing it until you go FI. I think the solid white lithium grease is what you want, I use it lightly on my poly bushings, please double check that before you apply it though just in case.

 

yeah my ingalls fronts sqeak like crazy!.......anyone else know?

Will it hurt to only run a 2.5 on sc FI then? And how often do you have to apply the lithium grease to the bushings?

That all depends on how much flow you will need. For moderate boost with a JRSC, I bet a kamikaze header mated to a 2.5" mandrel bent catback would work fine. The solid lithium grease, not the spray, is pretty hardy and sticks around for quite awhile. I have not had good luck using the spray.

 

okay, cuz I don't plan on boosting very high (5-6 psi). So a 2.5 sounds like a better deal. Thanks for the replies.
