jonarob 0 Posted June 15, 2006 Just to confirm - 1.6 GTI 1990 on a G - is it the XU5J? I've tried a search! Share this post Link to post Share on other sites
Anthony 1,003 Posted June 15, 2006 (edited) XU5JA - the later 115hp 1.6 GTi engine XU5J was the early (pre-1987 IIRC) 105hp 1.6 GTi engine (edited as Alan points out I can't type ) Edited June 15, 2006 by Anthony Share this post Link to post Share on other sites
Alan_M 66 1 Cars Posted June 15, 2006 XU9JA - the later 115hp 1.6 GTi engine XU9J was the early (pre-1987 IIRC) 105hp 1.6 GTi engine Are you sure its not a XU5JA? The '9' denotes thats its a 1905cc, whereas the 1.6 is a 1580cc therefore a '5' Share this post Link to post Share on other sites
Pete C 0 Posted June 15, 2006 (edited) Yeah, it'll be an XU5JA. The early 1.6 was an XU5J, and the 1.9 (8v) is an XU9JA... Edited June 15, 2006 by Pete C Share this post Link to post Share on other sites

Pete C 0 Posted June 15, 2006 cheers So does anyone know what spark plugs I ideally should use? http://www.sparkplugs.co.uk reckon NGK BCP6E or Champion C7YC Share this post Link to post Share on other sites
jonarob 0 Posted June 15, 2006 (edited) I got the BCP6E but my dad seems to think they're wrong. The Haynes ain't exactly helpful. Anyone know what the gap is? We're faced with 2 choices but can't work out what it is. The electrode gap that is! Edited June 15, 2006 by jonarob Share this post Link to post Share on other sites

jonarob 0 Posted June 15, 2006 0.9mm is ideal apparently Thing is the choices in the Haynes are 0.8 and 0.6 - sure you don't mean 0.8 or is the Haynes wrong? Share this post Link to post Share on other sites
Pete C 0 Posted June 15, 2006 I just used the 'search' button, and found that Haynes reckons 0.8, but a few people have used 0.9 and found that it helps with idling etc Share this post Link to post Share on other sites
MartinM 0 Posted June 15, 2006 With a wasted spark coil, I use 1.6 (40 thou in old money) - you get a heck of a spark from these coils, so you might as well get benefit from a physically bigger spark in the cylinder... Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted June 15, 2006 Errm 40thou = 1mm, 1.6mm is 64thou Share this post Link to post Share on other sites
Pete C 0 Posted June 15, 2006 1.6mm to me sounds excessive anyway, but then I only really have tuning experience with turbocharged engines... Share this post Link to post Share on other sites
