evinX Posted December 14, 2017 Share Posted December 14, 2017 Isnt it usually NA head gaskets they fit to TTs becuase the NAs are high compression. So why remove the better gasket for a inferior one? Link to comment Share on other sites More sharing options...

So why remove the better gasket for a inferior one? possibly, but they change to a TT HG for the NA as it's thicker and lowers compression allowing more boost I believe Edited December 14, 2017 by ben_harmer32 (see edit history) Link to comment Share on other sites More sharing options...
sidewaysdan Posted December 14, 2017 Share Posted December 14, 2017 (edited) THE tt head gasket is used on the na to lower the compression so you can up the boost. I also run a tt gasket on my na-t so now run 1.2 bar Edited December 14, 2017 by sidewaysdan (see edit history) Link to comment Share on other sites More sharing options...
evinX Posted December 14, 2017 Share Posted December 14, 2017 Ah ok got it Link to comment Share on other sites More sharing options...
Style Posted December 15, 2017 Share Posted December 15, 2017 Only guess about the part numbers being different is that it's non-vvti and vvti. If you can find out which one is which then go for the non-vvti one you'll be fine Link to comment Share on other sites More sharing options...
steve spedd Posted December 15, 2017 Share Posted December 15, 2017 OR you can fit the TT pistons and install an NA gasket. That's what I have. Link to comment Share on other sites More sharing options...
