    doing an ls2 intake swap

    i'm thinking about doing an ls2 intake swap but i would kind of like to know what all is involved in doing this...i know i need a different tb but will i need a different harness for the bigger tb? will the stock injectors still work?

    05-06 GTO car accessories(water pump, alt. bracket, etc.). The injectors you get with the intake will work fine or if you plan on other mods later on... go ahead and install larger ones. I would suggest a cam and a BIG stall all at the same time with this swap.

    I'm not doing a full engine swap, just an ls2 intake for the stock one...

    I traded some injectors for the intake so all I'll need is a 90mm tb and an adapter harness...I should gain 20 hp from this mod in theory...thats pretty goog for 200 dollars.

    20 hp at 5500 rpms...at the crank, not the wheels. Your gonna lose 20 ft lbs of torque across the board. Don't Do It. If you just want to spend $200 get you a throttle body spacer and be done with it.
