Looking for a set of FIC 1200cc injectors.

Looking for a used JM Fab Coil Pack Bracket that mounts the coils to the back of the block.EDIT: I found my bracket after looking for 5 days. I appreciate everyone reaching out.

I have a pair of new Crower 272's in the box still. You can run stock valve springs with these. I ended up going in a different direction so I don't need them. I'm selling them for $300.00 and buyer pays shipping.

Can someone tell me what the relay positions highlighted in yellow above the fuse panel in my 93 are for? I can't find it in any of my manuals or the DSM CD.Sorry for the poor quality of the picture

I am looking for clearances for putting together a long block. I know most engine builders have their own spreadsheets for this. Are there any engine builders who would be willing to send me a copy? or anyone who has bought an engine and was supplied with engine blueprints?

I am trying to install a Turbosmart boost T on my friends diesel truck. I need the boost T to hold more than the 20 psi that it is doing now, looking for 65psi. Some have told me that I will need to install a stiffer spring. Does anyone know for sure how to do this?
