What size turbo for 94 Lightning
 

Wanting to put a turbo on my first gen lightning, it has hyperteuctic pistons in it, stock truck. What would be a good size turbo to put on it, I was thinkin maybe 2 t3 or t4 stock turbos off of turbo coupes or svt mustangs- only looking for around 8 lbs of boost, nothing major. If anybody has any ideas or can give me some info it would be appreciated! Thanks.
