  1. Seems great so far

    Posted by Wesley Jordan on

    I bought a 240sx with a sr20det BT and found out later that it had blown head gasket. I took a chance with this one after reading a couple reviews. I am glad I did. I've had this in for a few weeks now and it seems to be doing great. The car has cp pistons, eagle rods, bc stage 3 cams, and BW turbo pushing about 22lbs of boost right now and this head gasket seems to be up to the challenge.

  3. tomei quality

    Posted by sean larson on

    After up grading to a tomei m7960 and increasing boost it was time to upgrade the hg. Tomei install was straight forward with sr20 fsm. Used new nissan head bolts. Tomei recommened to not used copper spray because of coating that was added to hg when it was manufatured. Holds the power. Very happy with quality and price.
