I Have VXR8 2008 and I have alread installed all the parts below (signature) but still didnt take my car for a dyno tuning .

1. Will I need to replace my stock injectors and ignition spark plug wires ?

2. Can I add a supercharger in the future time ?

Stock injectors are good for 500 N/A HP. You have a FAST intake, so I assume you want to add a Vortech or ProCharger. Depending on your cam you can add either, but then fuel sytem will need an upgrade.

Thnx GRRRR8 n I liked your modifications

If I plan 2 go for a supercharge in future, will I need 2 replace the stock pistons and connecting rods ?
Was thinking to go with 3.5" g force aluminum light driveshaft, my friends told me its smiler 2 Pontiac G8 size but still not sure if will fit in my car ...!

If you add a Maggie, you'll lose the FAST. The plug wires are good to go though.

stock pistons will be alright.however you will be limited to the boost you can safely run.

He has 32lb/hr stock LS2 and not the 39lb/hr stock L76/LS3/LS7....so maybe a tad less.

It's going to be similar to a G8-GXP with T6060 manual trans , except you have the T56 manual trans (not sure if length is identical)

There's no way to even guess unless you can provide more detail on your cam.

It depends on which supercharger, what boost & what other modifications the Supercharged R8 has......you probably won't come close unless he went cheap & you nailed your cam choice.
