Hi-Boost Engine Kit, 2.4L LE5 Ecotec

$ 499.00

A great way to prepare your Ecotec 2.4 LE5 for the rigors of higher boost, this kit includes:

  • Compression-lowering head gasket, reduces C/R to 9.2:1 from 10.8:1.
  • Cam drive hardware to accommodate thicker gasket
  • ARP Cylinder Head Stud Kit

Intended for early model engines that feature OEM forged connecting rods, as found on 2006 and some 2007 LE5.  Suitable for up to 18 PSI boost.  Higher boost levels are not recommended without also upgrading connecting rods.
