Suprash Posted August 14, 2015 Share Posted August 14, 2015 Hey, so when using a GE block to turbo, you either fit GTE pistons or a GTE HG to lower the compression. But what if you used GTE pistons and a GTE HG with a GE head ? How does that affect things or what outcome would we expect ? Link to comment Share on other sites More sharing options...
David P Posted August 14, 2015 Share Posted August 14, 2015 Compression would be too low if you used both, can't remember the ratios but do a search and they should pop up, N/A-T section maybe? Link to comment Share on other sites More sharing options...
David P Posted August 14, 2015 Share Posted August 14, 2015 Here you go. http://www.mkivsupra.net/vbb/group.php?discussionid=96&do=discuss T.T. pistons with T.T. head-gasket = static compression 8.1:1 ~ Capacity for more boost than bottom end can take and give a laggy launch ~ Squish 3.25mm T.T. pistons with N/A head-gasket = static compression 9.0:1 ~ Good for 2 Bar (99 RON) ~ Squish 1.14mm (750? bhp) N/A pistons with T.T. head-gasket = static compression 9.2:1 ~ Good for 1.8 Bar (99 RON) ~ Squish 2.15mm (700? bhp) N/A pistons with N/A head-gasket = static compression 10:1 ~ Good for 1 Bar (99 RON) ~ Squish 1.14mm (500? bhp) Link to comment Share on other sites More sharing options...
Suprash Posted August 15, 2015 Author Share Posted August 15, 2015 Thank link dont work but those CR's, what head are they using on that basis ? Im asking because someone has just built a NA-T using GTE pistons and HG. Now at 1bar he appears to be making around 450rwhp and at 1.5bar he's 515rwhp.

David P Posted August 15, 2015 Share Posted August 15, 2015 (edited) If you join the Club NA-T it will. http://www.mkivsupra.net/vbb/group.php N/A head as you requested. Your gratitude is underwhelming! Edited August 15, 2015 by David P (see edit history) Link to comment Share on other sites More sharing options...
