if you have a DX you'll have some trouble. mainly because the car is carbureted and everything from the gas tank forward is different because of the engine you plan to put in is fuel injected. i read somewhere that you can avoid having to strip all the lines out by buying a Motec computer. i have an 85 DX and planning to do this next year.

my friend had an 87 Si and we did a ZC swap over a weekend about 2 years ago.
