As the thread says are there any good off the shelf packages that would help the coupes performance without breaking the bank?

I've found that those intercoolers on Ebay, usually named "medium intercooler", are good. around 2psi pressure drop across it and good thermal efficiency doesn't drop off until 300 bhp.

Try to get an intercooler with at least a cross section of 76mm thick/250mm tall (300mm would be perfect!)or 90mm thick /200mm tall.
Inlet and outlet pipe should be with inside diameter of 57mm (external diameter 63-70mm).
Below those dimensions you will have some unwanted lag even with stock turbo.
