lukEp Posted June 29, 2011 Share Posted June 29, 2011 as far as i'm aware the only gt engine or 4efte to have the thicker rods are the mk1 gt engine with the silver cam cover and cam belt cover which is why i replaced my glanza engine when it let go to a mk1 gt engine with silver covers...... luckly i found one with only 12k on it including the turbo and all aux and i could tell when i took it apart to fit all the glanza bits like alt knock sensor and few other bits Quote Link to post Share on other sites

nastyrash 2003 Posted June 29, 2011 Share Posted June 29, 2011 yep i have found differences with the cylinder heads also the earlyer 4efte have very nasty edges in all ports wer the cutting tool cuts the ruf cast to insert the valve seat, wer as the later 4efte has ner anuff no edge but the same valve seat and size plus the coolant jackets around the exhaust valves seem to be larger on the early 4efte head.chris Quote Link to post Share on other sites

nastyrash 2003 Posted June 29, 2011 Share Posted June 29, 2011 That's interesting nastyrash. Will have to look at my heads when I get home. I have three in my work shop ;)the 1s with the nasty port throt edges seem to be the heads that have the extra water jacket on the inlet mani and gasket. this will reduce hp by quite a bit, i can put pics up as i have 1 here that im porting and polishing now.chris Quote Link to post Share on other sites
aidanep71 Posted June 29, 2011 Share Posted June 29, 2011 so your prob better off with the newer type engine anyway Quote Link to post Share on other sites
nastyrash 2003 Posted June 29, 2011 Share Posted June 29, 2011 its strange have found these 2 different heads on N/A and Vs and GTs, but do not know the history of the cars and engines and heads may have been swapped, but thr is defo 2 different heads out thr.chris Quote Link to post Share on other sites
lukEp Posted June 29, 2011 Share Posted June 29, 2011 mk1 gt head (the better as the hole for valve is cut bigger)there after see the messy machine marks. Quote Link to post Share on other sites
nastyrash 2003 Posted June 29, 2011 Share Posted June 29, 2011 cheers bro. luk is the libary wen it coms to this stuff. the second port will kill hp right from the off. the turbulance it creates just before the valve head is crazy. Quote Link to post Share on other sites
