Here is a list,

K04 - j31 file ~1500 w/ fittings etc
TT injectors (340cc) i think ~$249
TT maf (3in Maf) ~$130
5.0bar fpr (maybe 4.0 bar) ~$150
test pipe ~$190
fmic ~$1000
just for fun since you are going big, high flow exhaust manifold ~$325

total = 270-280hp @ crank
price = $3550 ish

moral = bad *** sleeper

 

Im pretty sure APR claims a solid 255 hp with there KO4 kit.

 

I am pretty sure with the Carbonio airbox, the shop that put it on took the MAF off. Could that be a reason why my car is idling weird at times? I dont think the MAF would even be able to go back on. No room for it.

 

still, that is a pretty complete list and u would be very happy with those numbers (for now)

 

no its on there. i installed my own carbonio intake, the MAF is there or your car wouldn't be running very well if at all.

 

Wheres it located with the box on?

 

trace reverse from your turbo up the inlet pipe @ the end should be the maf

 

One more thing: Will I need tuning for those injectors? I know that on some other cars that I worked on (mainly v8s), you needed to tune the car to get them to work.

 

the j31 file is made for bigger injectors... hence the tuning will already be done.

 

Go motor! The K04 is a great stop light sleeper
