Well I'm puttin the fd twin turbo in my 87 fc so im just lookin for an upgrade

 

I recommend a single turbo swap if you do that. I have all of that outlined in a thread at the top of the section. Good read and informative.

 

Well I already bought the twin and as soon as I bought it found out it's better with the single also how could I upgrade my twin it's only 280hp is there a way to convert it to single or is it better to upgrade the twin
