106 GTI engines to 205 chassis

I aim to put 106 GTI engines in 205 cases, but I have some question marks in my head. First of all, does the engine fit without problems, secondly, how can I strengthen the engine?

These things are looking for money, I have limited budget, and if you say that it is zero in the pocket at the end of the job, do not enter it, because I know that I thought I would swap 1.6hdi 110hp to my 1.4 hdi vehicle and investigate it and it may cause difficulties in parts such as more than 10 thousand numbers. exhaust cover port polish suction polish arm piston thin seal brain etc. nice powers are taken but it finds so many good coins

Straight 205 1.6 Can I get some efficiency if I do what you mentioned about GTI? Except itb
