swap + turbo + tuning hrm lets see.

stock ls swap : i dont know cheap.
drag kit - 2500 when you find a deal
hondada - 1000 includes tuning n injectors
275whp
3500 do we have

b20 block 800-100
b16 head 300-600 assembled
good cams 500
sleeves 1000 (b/c otherwise the b20 cyls will crack, dont dare say otherwise)
hondata 500 includes tuning
cam gears 150
pistons 400
rods 400
being very conservative we're already over 4k for this barely doing 200-210whp motor that will always be at its max.

with the turbo car the power is only there when you need it.
