a good 3rd Gen RX-7 rolling chassis: $8000-$10,000
LS2 Crate engine (6.0L 405HP): $6500
Granny's Speed Shop conversion kit: $2300
NX 150 shot dry kit: $750
custom 4'' single exit exhaust: $500 (at TBC

)
T-56 Transmission (new): $3000
tires, suspension, misc. expenses: $2500
Clutch: $1100
all of these prices are quoted as brand new. im sure you can get a hell of a deal on a LS2/T56 pullout of a wrecked 6.0 GTO for alot less. just my .02 of course. when i get the money, this will be the way i will go. not a doubt in my mind.
now enjoy your new ride!
or you can just buy one already done for about $30K. with that setup right there, you can do 10's on DR's all day long, not to mention eat up nearly any supra that tries to fuck with you. the car can be auto-x or drift setup too. still keep the perfect weight balance. can you say 550WHP in a 2900 lb car?
