new to mitsubitshi
after driving 6 different hondas for 12 years (NA and boosted), i've decide to have something else a try. well, it wasn't really a choice, my wife told me to get ride of the hatch and get a 4-door car because we just had our first son. so i figured, if i'm going to get a 4-door, i'm going to get a bad *** one. the 3 car i had in mind was the acura TSX, STI, and Evo. TSX is a nice car but front wheel drive only, STI are also nice but too hard to work on because of the boxer engine, Evo won because it's a nice car for mods and easy to work on. So i picked up an 03 Evo this weekend and i love it. I just have some general question. here are the current mods.
-Injen Intake system
-Injen Upper Intercooler piping
-Hallman Manual Boost Controller with in cockpit adjuster (set at 21psi)
-Custom built 3” Turbo-back with Random Technology hi-flow cat (no muffler)
-Walbro 255lph fuel pump
-Turbotrix flash
what would my estimate whp be at with these mod and what other mods can i do to get 350whp with out touching the block. can i do it on the stock turbo. i want to keep spool time as low as possible. how hard can i launch the car on stock clutch, what rmp. thanks for any response.

260-270 whp now is probably a good ball park. Might be a little low.
Cams should definately be next on your list. They'll get you to @ 300 whp. afterthat I would get with one of the tuning companies and get their advice on were to go from there.

i didn't think the stock turbo can handle 350whp. i can do the cams but not sure if i want to go with water/alky injection, i know they are great benifit but i want something that's maintenance free. what about the stock injectors, can they handle 350 whp with the walbro pump. also, can stock bottom end handle 8000 rpm. it fell so werd shifing at 7k, i'm used to shifting at 9k rpm.

Tuners are raising redlines to 7800 and sometimes higher on the stock bottom end, so yes, you can get at or near 8k rpm without touching the block.

well, according to the previous owner, the car was dyno tune by turbotrix and make 319hp 307tq, i thought it was kinda high with the current mods but i'm not to familar with this engine. i think my next mod is going to be cams and valve train to handle 8k rpm. and tubular headers for better spool time and maybe ball bearing turbo also. the want the best turbo response i can get and still be able to produce 350whp without chocking on the top end. also, is there any software that will allow me to edit a rom for the stock ecu. i've been tunning honda ecu for awhile and it would be nice if i was able to tune the stock ecu.

So, that 1.76 60' is on stock tires and stock clutch with the 5k launch limiter switch removed (you don't have this feature).

You don't need a new turbo at all. The stock turbo has plenty left to go after 350 WHP.
Get injectors and cams, turn up the boost a bit, and you'll be around 350 WHP. You might consider a piggy back engine management system. That with someone who knows what they're doing to tune it, is going to put you beyond your 350 WHP wish.
