Default My 2.5 build will be complete in 1 week!! Need expert opinions!

Ok, i have a lightly modded 01 2.5 rs My existing mods are:
strommung 2.25 cat back
random tec hi flow cat
newest gen borlas
cobb CAI
unorthodox UD pulley
Cobb mild cams.
KYB AGX w/ ground control springs (adj ride height)
whiteline adj swaybar (set on 20 mm)
cobb short shifter
WRX rotors and brackets (front)

I have been saving/ planning this for a long time and i am going up to lachute subaru to install a whole mess of goodies...here are my plans.
Port matched ported and polished cylinder heads
matched valves (5 angle valve job)
cobb springs and retainers
Cobb racer camshafts (newest most aggressive n/a grind cam)
exedy clutch (+30%)
16 pound machined stock flywheel
ZEX 55 shot nitrous kit
new fuel pump
colder range (7's) spark plugs

I have to arrange an appointment after i make my custom intake manifold with my brother for my car to go back to lachute for unichip tuning..im also raising my redline to 7,250 rpm to get the high end power Im going to be making with my set up. This is safe with my springs valves and retainers from cobb.

So, I just posted this to get some opinions, Im sorry if it looks like bragging, but Im honestly not. I am just looking for reccomendations and opinions on my n/a setup in an n/a forum. i appreciate any comments and opinions (both negative and positive) and also warnings and experience with anything that i am doing. Thanks everyone!

Dan

Yes I am, when i go to get the unichip on my car, lachute subaru (they have a prodrive contract) will convert my car to rwd to tune it on the dyno, and later during the year they will have acess to a 4 wheel dyno, so they said I can eventually put my car on that too. When i get the rwd dyno numbers, 4 wheel dyno numbers and 14 mile numbers I will be sure to post them!

that setup you got sounds really nice, and reliable. i was just wondering how much you are paying to have it rebuilt. also, do you know if you will pass emissions with that setup? what do you think youre 0-60 and 1/4 times would approximately be? really nice and good luck! you should look into gettin those chalek hardened gear sets for the tranny too.

I've heard that the STi tranny and engine mounts send a lot of vibration into the car, is this true?anyone with experience? Do you think they are really nesessary? Thanks for the thought!

well, I have the STi tranny mount, and its a pretty good balance of solidity and vibration/noise. I notice a bit more noise and slightly more vibration, but the drivetrain doesnt knock around as much as before. With the engine mounts, it'll be ROCK solid tho, and transmit more noise and vibes.

Do a search under 'tranny mounts' and read what other people have said

my .02?
don't go any further N/A.
spend a little more and go turbo. The cost per H/P n/a is just obscene... IMHO.

I've heard nothing but bad things about lightening the stock flywheel. And not just from Subaru's.
Spend the money and get a good aftermarket lightweight flywheel.
Other than that, I'm jealous

Turbo charged cars are great I've driven quite a few (my brothers), but the reason im going this route is because its different. I was torn between going turbo or doing a build, but the idea of a build is just simply more appealing to me and is what i really want to do to my car. It boils down to a simple preference i guess...good point though on cost/hp. Anyone else??

I think it sounds sweet, and completely understand the idea of not going turbo in order to do something different. I would LOVE to hear some results, hard numbers, butt dyno, grin factor, etc. A cost break down of the parts and labor would be really cool too, if you're bored and feel like typing...

maybe a bit expensive but have you thought about oversized valves? maybe help a bit more air flow through there not that you'll need it with the cams though.

Throw in a bigger throttle body? It can only help.

These are good points guys, thanks!

ill look into the lightend flywheel option, but the guy at lachute who has a supercharged 2.5 loves hi flywheel to death, so im a little stuck on this one, iwas originally looking at the fidanza fly, but the stock one seemed right for what i needed.

Oversized vavles arent nesessary, both cobb and lachute subaru were against oversized vavles for my car. The valves are machined to match the heads aswell, they arent stock.

I forgot to mention the new throttle body I'm putting in too, i wouldnt forget that!

Higher compression pistons? And why not get a link + for a couple hundred more and having the tuning options? Sounds awesome though can't wait to see the dyno numbers and maybe a video if possibe preferably with audio in a tight enclosed space as to hear it echo of the walls nice and loud.

Pistons will come poppa smurf ! Be patient . i decided not to do the pistons yet, but that will be the icing on the cake i admit. I will DEFINITLY post dyno #s, when I go to tune the unichip they will make my car rwd and plop it on the dyno, so ill have rwd numbers for you guys, eventually they will have acess to a awd dyno so Ill do that eventually.

I will do a full length, sound included video of my car when i am completely finished. I will also vidoe my 1/4 run too, I just need some time. Believe me, everyone will know how it goes!

It's becomming harder and harder to sleep!
