After months of testing and refinement, we are now pleased to offer forged pistons
for the GM LUJ 1.4T! We dropped the compression ratio to 9:1 compression
to allow stratospheric boost levels to over 28 psi. Upgraded valve springs were
also developed as drop-in replacements for your stock springs to handle 28+psi
boost and a 7000+rpm redline.
