jono Posted May 26, 2005 Share Posted May 26, 2005 Apologies for this one again, but.... I have a 1.4 factory built supersport which is about due for an engine rebuild or upgrade. I really enjoy the revvy nature of the 1.4 and character of the car 135bhp - 140bhp is more than enough for me so it would appear that I have 2 choices, either upgrade to 1.6 which i understand can be done by combining a 1.6 short enginze with my 1.4 ss head, sump etc. or rebuild the 1.4 in which case I would like to tweak it up to around 135 - 140bhp without losing reliability. As I understand it the 1.6 is the same stroke as the 1.4 so this should rev in the same way(?) What output could be expected by doing a straight swap to a 1.6 (to effectively create a 1.6 supersport)? If I rebuilt the 1.4 how could I achieve some modest gains in torque and power as described above without sacrificing reliability. Car currently runs on a 4-1 exhaust which i would ideally like to retain. (car is 6 spd) Advice appreciated Edited by - jono on 26 May 2005 14:10:04 Link to comment Share on other sites More sharing options...
Dannyboy Posted May 26, 2005 Share Posted May 26, 2005 Hmmm....think you have to replace the MEMS for the 1.6??? someone will correct me hopefully... I've just done the 1.8 conversion...same as with 1.6, reused existing s/s mems, cams, flywheel etc...Just get a bottom end, headset etc etc and the bigger injectors/ fuel rail.......mucho mucho fun! Not as revvy....but much much quicker!!! 5th is a gear you can actually accelerate in now!! 😬 😬 😬 Link to comment Share on other sites More sharing options...
oilyhands Posted May 26, 2005 Share Posted May 26, 2005 The 1600 is just as 'revvy' as the 1400, if you up your fuel pressure to around 4 bar you can use the old MEMs/head/injectors etc. 1600 short engines are easy to get hold of I have a 1600 bottom end here and a good set of low mileage pistons on rods that you can have for peanuts. oily Link to comment Share on other sites More sharing options...
Englishmaninwales Posted May 26, 2005 Share Posted May 26, 2005 Jono I'm with Daniel with this...... go 1800. Easy upgrade and not too expensive. Makes a big difference, although mine was a 5 speed 1400 which is significantly worse than your 6 speed. Email me if you want some details, costs etc Malcolm Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted May 27, 2005 Leadership Team Share Posted May 27, 2005 I'll third the 1400 to 1800 approach We're now establishing the converted 1400 owners club 😬 Stu. Link to comment Share on other sites More sharing options...
