What changes were made to the Z28 from 1998 and newer? Interior? Exterior? Drivetrain?

Thank you...

98 and 99 had the 5 spoke wheels, in 2000 they switched to the current 10 spoke wheels. In 2001 and 02 they got an LS6 intake, a slightly stronger cam and no EGR. Interior has stayed the same and really depends on options.

Thank you very much.. I guess the wheels are easy to change if that's what you like. How much power did the other options add? Sounds like you could update those as well if needed...

other options added maybe 10 hp

99 the switched over to slightly smaller fuel injectors. I think the valve covers bolt on differently than 98.

2000 I believe the went to cast iron exaust manifolds

Umm, I think in late 2001, 2002 all LS1's get the LS6 clutch and pressure plate, which is a tad stronger. This is now the stock replacement for all LS1's..

The 2001's have a bit more low end tq, and supposdily because of the ls6 intake, they keep the same peak hp..

98s and up have a bump on the passenger side of the floor which is for the V6 cat. but is still on the V8s.

The 93-97 has the same hump in the pass. floorboard.

98=28lb injectors
99/00/01=26lb injectors
02 28.5lb injectors


not sure bout 01 so i just took a guess

10% of 2001 and 25% of 2002 have the LS6 blocks.... which evacuate downstroke air to adjacent chambers.

ls6 block does nothin no hp gain not a ls6....no internals

Just kidding

psychocabbage

i never said any power gains.. just the benefit you gain from that block.. i need to lift the car to know 100% for sure.. we shall see tho.. doesnt really matter but its just a kewl "what if" if you do have it.. ya know?

99 and newer have slightly larger gas tanks, don't they?

stik6shift98

ya or an easy way to find out is to see if there is a bulsleye on it or not....or u can see by the produt number.....
