Hi everyone! New member here all the way from Finland. I have an idea that I wanted to run by you since you might know a bit more regarding these things. I have a MK3 Clio GT and as you might know the engine it has is the K4M.862 the twingo rs engine K4M.854 is very similar. The only differences they have that I know of is the twingo has a higher compression ratio and the airbox is a bit different. They both have the same OEM numbers for the parts within the cylinder head so I have ordered catcams twingo rs camshafts and valve springs for my clio gt. Can you think of any issues that might occur? I already have a 4 to 1 decat manifold and 2.5 inch exhaust all the way through. Also have a K&N panel filter and once everything has been installed I will get it dyno tuned.

If the cylinder head is the same part number I can't see any reason for it not to work 
Let us know how it goes!

Big update! So today I got the car tuned on the dyno and it made an fairly impressive 156hp and 181nm. Considering that stock is 128hp and 155nm, I am very pleased. Feels really nippy. Rev limiter was raised from 7000rpm to 7150rpm. Going any more past that, the tuner said that it was starting to run too lean. No knocking though. The tuner recommended getting about 15% bigger injectors so that we could raise the rev limiter to 7500-7700rpm and break the 160hp mark. I already have IWP-042 injectors that the mk3 and mk2 Clio RS use, but these are a little bit too big. Does anyone have any recommendations regarding what injectors I should get?
