Elantra v6 swap
 

I have been thinking about doing a motor swap on my 03 Elantra and putting the 2.7 v6 in it. Does anyone know how should approach this and what kind of difficulties I could run into?

Don't waste your time. You will make more power and spend less money adding a turbo instead. V6 swaps into Elantras can and have been done using alot of 2003-up Tiburon parts and custom made parts but it costs a lot of money and time. And while I love the Tiburon and the 2.7L engine, it's not really the strongest engine out there. Do yourself a favor and look into adding a turbo.

Well what is a good website to go to for turbo kits and other performance parts for Elantras? Most I have been finding is kits for Hondas, Mazdas, Nissan, Toyota, but no Hyundai Elantra
