Hope you don't plan on running more then 6psi of boost with those 60 lb injectors. at 8psi I was at 98% duty cycle with my 60lb siemens deka injectors on a 5.3L. This was at 43 psi base fuel pressure. I've also got a twin Walbro 255 set up with a -10 feed line. I've recently upgraded to 80lbs

 

The intercooler I am using on my Datsun is a 20" x 12" x 3". Fits perfectly between the openings on the side of the core support. Its always hot / warm on one side and very cold on the other. Data logs don't show IAT's rising excessively either. I paid 130$ for it off of Ebay.

Check out the Garrett site. It's a good read and has very good basic turbo and intercooler sizing information.
