Piers7 Posted September 13, 2008 Share Posted September 13, 2008 I have the 1.6 ss engine in my Superlight and was wondering what the cost would be, parts and labour, to upgrade to 1.8? Is it just the crank and rods that need to be changed? Thanks Link to comment Share on other sites More sharing options...
oilyhands Posted September 13, 2008 Share Posted September 13, 2008 In reality you cant easily swap pistons from one rod to another without compromising both the piston and the small end interference fit. The ring swept area and traverse area are different on the 1800 so the liners wont be ideal either, you would be best off with a good matched set of 1800 rods, liners and pistons together with a good used crank.

Piers7 Posted September 13, 2008 Author Share Posted September 13, 2008 Thanks for that Oily Any idea what that little lot would/should cost me? Superlight #115 Link to comment Share on other sites More sharing options...
oilyhands Posted September 13, 2008 Share Posted September 13, 2008 As it happens I have a number of good secondhand cranks here and a good set of 8000 mile 1800 rods, liners and pistons. It's hard to say what you might get a set for, but I can give you a price if you email me direct. Oily Link to comment Share on other sites More sharing options...
Englishmaninwales Posted September 13, 2008 Share Posted September 13, 2008 The power gain is pretty minimal, and you'll loose the free reving characteristics of the 1600ss. There is, however, a small gain in torque.The 1600ss and 1800ss cars in classes 2 and 3 in the L7C sprint competition are very evenly matched. For the cost, I would spend it on something else.

Mark Durrant Posted September 15, 2008 Share Posted September 15, 2008 I agree with Malcolm and if your looking for more power I would have the head ported, fit a set of verniers and a 52mm throttle body. Mark D Comp Sec Link to comment Share on other sites More sharing options...
david nelson Posted September 15, 2008 Share Posted September 15, 2008 keep with the 1.6 and either put TB on or get the head ported. Be careful or you will talk your self into spending lots of money with little affect. If I had a 1.6 i think i would just pop some Jenveys on and get it mapped. Why take the engine to part if all is fine? If the engine comes apart I am sure you will be told it needs this and that the liners might drop, if it done X miles this could be wrong ect.......

Nick Pargiter Posted September 15, 2008 Share Posted September 15, 2008 Keep what you have for now (unless it needs a rebuild) and just add on all the bits that don't require taking the engine apart, ie TB's, verniers and an Emerald plus mapping session. If you want a bit more and have the cash then get the head ported and maybe change the cams. Nick Link to comment Share on other sites More sharing options...
Piers7 Posted September 16, 2008 Author Share Posted September 16, 2008 Thanks for all the advice chaps Maybe i'll go the 1.6 screamer route then 😬 Superlight #115 Link to comment Share on other sites More sharing options...
Tre Zarcoff Posted September 16, 2008 Share Posted September 16, 2008 And if you change the cams, and port the head,you would be wise to fit forged pistons as well as the standard pistons won't be happy for long. So, if you go the 1.6 screamer route budget for new pistons. My Jenveys, verniers and emerald only left me wanting more! I like cream... Link to comment Share on other sites More sharing options...
