So I finally have my Evo paid off and a daily driver back in place. My warranty has about 4k miles left so i figured now is a good time to start the modification process.

I definitely don't want to get crazy, I am shooting for ~350 Crank HP. Also, i would like to keep the costs down. Here is what I am thinking:

Muffler delete "axle back" exhaust (15-20HP?):

This is a bit pricey for a pipe, i am working with some other vendors to find a less expensive one.

K&N High flow air filter (5-10HP?)

AMS Intercooler (20HP):

Also a bit pricey but sounds like the best bang for the buck. Increases airflow by 80%. Plus having the "AMS" Logo in front is just cool.

Flash? Is this necessary with these mods and how much HP will I get out of this?

Evo9 BOV:

So I think that puts me at around $1400 for 350HP? Lemmie know your thoughts. I will also be putting on a Beatrush undertray and polishing everything up with Mother's

 

dont think thatd get you to 350

 

350 was a high guesstimate. Maybe more like 320-330? Also, what will my turbo spool at with the increase in flow?

 

You're forgetting Manual boost controller and tune.

 

GM solenoid and tune

 

yeah i was about to say mbc, then def flash with that. the stock boost is so f'd up, just flashing it stock would get you alot of gains. and i honestly couldnt describe the increased spool sorry

 

Manual boost controller, set it at 21-22 psi, intake, exhaust, IC pipes, intercooler and a tune.. should be reallly close to 350 CRANK power..

 

yeah ide like one of those. wow that would just make things so much.... idk, but you get it... ecu based lol

 

any recommendations for the tune?

 

yes i forgot you emphasis on crank, makes it a bit more reasonable. and yeah spool will improve with the ic piping, mostly lower if you cant get both. but i hope that was given if you were planning on the AMS ic

 

Well, actually the AMS IC bolts into the stock IC pipes...

 

i believe it would but it would be dumb to not get the ic piping to go along with it, it will help flow greatly. not to mention you'd already have everything apart

 

Fair enough, i will put it in there. I am doing some reading on mellon tune, any suggestions there?

 

PM'd
