Why are all the newbies focusing on how much boost they want instead of how much power they intend to make?

dunno, maybe they like to say they are running 10psi (on a tdo4 and in actuality making the same amount of power as someone else running 5psi on a t3)...
(not actual numbers, duh).
after all doesnt it just sound cooler!

10psi on an EJ25 would be an awesome amount of boost but 10psi on my EJ22T would be junk. You guys are definetly right that boost is the last of the worries. However, most braging rights come from boost for some reason

sorry that is wat i mean.. i rephrase it ....wat whould i have to do to run (well just say 10psi) on a t3 turbo system... and how much power would i be expecting? am looking for something in 280-300 area someday... yea not now just someday.. am not some wanna be that thinks he can get 300hp without trying... i mean wat kind of enternal work would have to be done? and putting headers on a turbo car is impossible for these cars right(not sure used to be a honda person which couldnt) iono

also wat is teh stock dyno of a 02 2.5rs? with out making it s 2 wheel drive i hear its around teh number of 95 that is horrible that is like a 40%lost in power,o well... lets see i have about 3gs saved up from working.. i was think of getting a
-cobb intake
-cobb cams
-scooby sport exhaust with 2.25 or 2.5 inch pipping(unless u know a better one?)
-new ecu looking at tech II ecus
-some kind of pulleys (any sugestions?)

please be kind i am a newbie on subies but am learning

If I recall that 95hp figure came at some fairly high altitude. Think more in the 120ish range. 300hp is a reasonable goal with what you've got listed below, but if you're shooting for 5+ psi of boost, your clutch is going to start wearing out much more quickly. If you get a clutch that will handle 300+ hp you're going to be putting your transmission on the line... it's not a guaranteed failure thing... there are people who're running that kind of power on the stock gearbox, but there are also a great number who have splintered gears. Basically, following the recipie you've got below, a well tuned 7-9 psi of boost will put you where you're looking to be.

The problem with our cars is no one ever knows what the weak link is in any particular car. One person might blow a tranny while another with the exact same setup will blow a piston, and even another will run fine. it's a toss-up unfortunatly.

However, one thing is for certain. 300hp will be way to much for the stock clutch, blow up the tranny, and destroy a piston

You can get 280-300 _to the wheels_ with less than 10psi on a stock EJ25.

imprezinator is right....each car has it's own weak link. if you are aiming for 300 HP get ready to spend some tall cash....IIRC the 4wd seal level dyno got about 111 Horse to the wheels....remember AWD=higher driveline losses. takes more power to feed 4 wheels rather then 2.

Please differentiate whether you are seeking 300hp at the crank or at the wheels. Big difference.

Get real engine management and you can do that on your current motor.

man you guys should open a chat room... hahahahah

anyways many of the answers you seek you need to specify what type of DIY tuning you can/be willing to do or learn... also the goals of the car... budget etc.... there are already people doing it in a variety of different ways... I am a budget, average DIY tuner, daily driver ~300 to the wheels... ie... i use the unichip and can tuning it myself... but i'm going to take some time before going TEC 2 or 3... I blew a piston.... and what a lesson it gave me...

I use the TEC-II kit from Vishnu .

As always, speed costs, how fast do you want to go?

It can with a dyno, somebody who _really_ knows what they're doing, a lot of patience, and a little luck. The high output coils, high resolution crank angle sensor, and integrated control of the TEC-II and similar systems give them a distinct advantage over even advanced piggybacks, like the Unichip.
