wow.. Thats sick and the best part is here...
quote from other board.
"for 500rwhp SAE and 10.99 with good driver and ET Streets in an 03-04 cobra all you need is the following mods...
stock blower ported by Apten Performance $395
2.8 pulley-14psi $70
o/r X pipe $125
catback under $400
then you can add nitrous like I did on my car for under $1000. My total kit installed was under $600.
so for $1970 TOTAL figure $2100 installed, you can run 10's all day long.
With those mods and a small 30 dry shot into the air filter my car put down 530rwhp and 553tq SAE
The 03-04 Cobra is just like a supra, EASY to mod and go fast! You cant beat the class of the AMG cars though, this is why Im saving all my pennies for an AMG daily driver as my 800+rwhp cobra is my daily driver for now "
