3s-gte PRICING question, How much for a swap Options

[nObOdy]

Alright guys - i dont know if you know or not but ive been waiting around for a good deal so i can purchase my celli (still without one) and once i do im going to do the 3s-gte engine swap. Now, i have heard tons of different swap figures as in how much it costs but i was curious if this sounded logical...
engine $1500 (2nd gen) shipped $300-400??
mechanic says he can put it in for around $800-1000
going to change the exhaust size to a 3inch pipe back $200 dollars
new sparkplug wires plugs possibly an engine tune up.. $200
so im at 3,300 which is a lot less than a lot of people keep saying and thats being pretty generous i think on my part...
What am i missing? possibly a clutch? add $400-500

any ideas??

For a front clip $2k
Intercooler $200
Piping anywhere from $150-$300 depending on how you run your pipes.
Tune up stuff, belts, oil, seals $200-$300.

If you get an st you will need a new tranny $300 - as high as $1500 if you get the e153 with lsd.

So it will usually run anywhere from $3500 to $5k
