Ballparkish....how much? 2k? 3k? Anyone have any ideas?

 

Are you doing the work yourself? If yes its the price of the engine+ exhaust fab and accessories. If not probably about $3.5k.

 

It depends how you want to go. Your VG intake flows better than the VG30ET's does. So you could use your intake manifolds. If you do then you will have to get your ECU remapped at JWT with turbo program. Then there is the cost of a custom downpipe, intake pipe, BOV and other things. I figure $2500-3500 out the door depending on what you want done. Assuming you bought the engine for $600 from nippon motors then swapped your intake manifolds to it. I figure the shop would charge about $1000-2000 labor. So figure at that aside from parts the labor is about $1000-2000 which is reasonable.
