Hey everybody this is my first post! So I have an 02 civic EX (d17a2) and i threw a rod. I purchased a d17a1 from an LX civic and I was wondering if it will be compatible. Im swapping the heads so it will still be vtec and i wont have to change the ecu. Ive done so much searching but im stumped. Anybody have some insight?

 

Bump!

 

It will work flawlessly

 

Ya i figured it would i just wanted some motivation before i swapped another engine in haha. Thanks man!

 

I believe the pistons are lower compression aren't they?

 

Ya they are i think they are 9:0:1 and the ex is 9:5:1
