big job obviously,but you will need the full v6 loom and all ancillarys otherwise it wont run,also the inlet and exhaust manifolds,modded mounts drive shafts,or are you going rear wheel drive?!
loads to do to get this to work but if your confident go for it.
ps thats a big power jump! 1600s alota money too id buy a cav turbo or calibra turbo and itl be faster and easier for you
big job! £1600 seems a bit steep too, it wasn't that long ago i saw a 2.5 V6 on here for £300.
Obv would recommend getting a brake upgrade too! Might just be easier to buy a GSI and spend you money on modding the engine in that? Your insurance will also shoot up as soon as you change the engine. Up to you though chap, do what you want to do! I have gone against what is the realistic thing to do hehe
