Jer309GTi 3 Posted March 11, 2006 Is this the same as a 106 GTi engine? Share this post Link to post Share on other sites
Sandy 191 Posted March 11, 2006 Nearly, different pistons (raised crown), bigger combustion chambers, slightly bigger inlet valves (which the 106 and saxo lot get over excited about), softer valve springs, different cams, different inlet bolt pattern, etc. Share this post Link to post Share on other sites
Jer309GTi 3 Posted March 11, 2006 Thanks for the reply mate. Are they similar in power/torque to the 106? Share this post Link to post Share on other sites
Sandy 191 Posted March 11, 2006 Torque comes slightly lower iirc, rumour is it flows better than the 106 head, but that doesn't always mean more power! Share this post Link to post Share on other sites
TB_205GTI 1 Posted March 12, 2006 Ported the head still gives lower figures than a ported TU5J4 head (106 GTI). The TU5JP4 (206) also has a different oilfilter system, and the TU5JP4 had the engine mount in the head - not the block. Sandy: Do you have en exact cc of a TU5JP4 head vs. TU5J4?
