I have a 2002 Chevy Trailblazer with the I6 engine. Looking adding more HP and torque to it to eventually set for the drag strip. I can not find performance individual coil packs or headers for my truck. Does anybody know where to find them? Also looking for inner engine performance parts as well.

I'm not familiar with the I6 engine, but whenever I'm looking for performance parts,  I automatically go to & As far as drag racing prep, I'd check local speed shops for engine work, this is costly but for safety sake, probably money well spent.

The I6 engine is really powerful for a 6cyl, but the common FI power adders just are not there. Since it is only used in 1 platform, manufactures really don’t want to spend the money on R&D (even though all they need to do is mod the I5 RKSport S/C with a different intake and belt...) to make one. The biggest issue has been tuning under boosted conditions, but now EFILive and HPTuners both can tune the I6.
