cost of the 5sfte, how much should it cost? Options

[6strngs]

alright, I've seen alot of people say that a 5sfte set-up could be done for like $1500-1600. but everytime I sit and try to calculate a cost, I end up over $2500... could someone possibly tell me how much it typically costs for a 5sfte turbo kit? here's what I figure:

3sgte stuff (turbo, manifold, downpipe, oil pan, map sensor, oil lines) $300-400
injectors $300-400
fuel pump $100
FMIC (including all pipes, couplers, clamps) $300-500
gauges $150-200
SAFC+BTM/emanage ultimate $600
BOV $150-200
exhaust $200-300

for a total cost of $2100-2700. abd that's before any dyno tuning! is there no cheaper way to do a 5sfte?
