Hi all, Just wondering if someone out there can help me figure this out,
I want to convert my 1.2 to a 1.4 and need to know if i can use the manual choke off the 1.2 on the inlet manifold of the 1.4 which is a single point injection from what i can see. What exhaust manifold would i need could i use the 1.2 one or would i need a different one??
(1.4 being 16v)

thanx in advance for anyone who can help :) :thumb:

The exhaust manifolds should be the same and why would you want to keep a manual choke if it has a working auto one?

does it have a carb or throttle bodie? if your not sure does the standard airbox mount with 2 or 3 bolts?. if you want to run the 1.4sr ignition but dont have the wiring then get your money out as it costs quite a bit. if you are changing it purely because your engine is knackered (what makes you think this?) then why not fit another 1.2 instead. much more straight forward

you could simply use the 1.4 bottom end with the top end off the 1.2

an engine number off the 1.4 would help massively.

i ran a 1.4 with a 1.2 top end & it was pretty quick
