Default great news! but need some advise and guidance

hey guys
so i am a freshmen at MSOE, a engineering college in milwaukee wi
the schools known for being pretty demanding and really hard (33% drop out rate for freshmen in the fist semester) ive been working my butt off here, seriously 7 hours of homework a night!!!

i have a 5 speed RS1 tC, i bought it just under 9 months ago and worked like crazy over the last school year and summer to bank as much money as i could to have enough saved up for my car payments during this school year, (i really pride myself on the fact that i can truely say that i paid for my car, most of my friends parents bought them their cars compleatly or 70%- RSX-s and a SRT-4)

my goal for the last few years was to get the TRD supercharger for my car, i have always dreamed about my setup.
WELLL!
a few months ago i applied for several scholarships, school here costs 32,000$
i look really good on paper and recieved 3 smaller scholarships amounting to 5,500$ not to bad, well last week i got an eamil saying that a big name company wanted me to come in for an interview for a possible scholarship + internship
i went in last tuesday and just got notcie today, that out of 14 other canidates, i was chosen

the scholarship is for 60,000$!!!!!!!!! over 4 years (15,000 a year)
plus!!! a paid 20.00$/hour internship over the summer

im only a fresmen in my first semester!!!!!!!

today is by far one of the happyest days of my life and on top of that i got an email literlay 15 min later from harley davidson saying they want to interview me because there interested in hiring me for a summer internship after i submitted them my resume

so with all the money i just got hands on, my parents agreed to help me out and get me the TRD supercharger


so without further adue, my question is

i will have about 1,000$ left over after the supercharger and install, im running a k&n cold air and TRD exhaust, thats it for performance under the hood

i would abosulty love to be able to get to 225whp

so how would this set-up be

-TRD supercharger
-bigger fuel injectors? if so what kind, how big
-new pully? 9.5lbs? or bigger, what kind?
-new chip?
-new reflash?
-dyno tune?
-for sure i want to get new header and downpipe, with resinators so i dont sound rice
-new fuel mapping system?

(ik that 1000$ wont buy all that, but what would be the most benefical?)

what else could i get or swap with the list above, ik theres water/meth cooling but do i really need that if my goal is 225whp

please be gentile on me guys, i know that there is a million threads on the TRD and everything that goes along with it, i have done alot of research, its just that when its finally you doing the mods, you want to make sure everything is correct and that your money isnt being wasted

any constructive criticism would be great and very help full, im in an amazing mood and will be for a while so dont be a mood kill by flaming this post

thats great news man congrats

as far as your question

if your willing to spend about 1k on top of the s/c i would get/do the following things

9.5lb pulley -$95
Bosch 110 bpv -$55
emanage - $300
(optional) emanage PnP harness - $300
tune - shop dependent apx $300


these will net ya more then the 225whp your looking for

hey thanks for the responce,
i figured that i would need a new pully, now that 9.5 is the amount that i would be boosting at?

and exactly what does the Bosch 110 bpv and emanage do and how hard is the install, is it something a shop would need to do?

and one more question for everyone, ive seen some people say that they have a BOV on the trd supercharger, is this correct, i heard somewhere that this isnt possible

i would love to have a BOV, even tho it does little for performance if nothing

the 9.5 is how many psi you will be boosting at

the Bosch 110 is a by pass valve (BPV) , its similar to a BOV. the stock one doesn't hold boost all that well in the mid range so most people upgrade it. with the 110 you will be able to hold a higher peak boost as well over the stock 102 unit.

its not safe to run a BOV with the S/C in a working mechanical sense.. however there are ways of running one in the intake tube purely for the sound...but then it becomes like them whistles you stick in your tail pipe to get the whoosh sound lol.. rice imho

the emanage is a piggy back engine management which means it works on top of the cars existing computer (ECU). however you will need to go to a tuner shop and get it properly tuned on a dyno. installation can be easy the emanage PnP harness, it allows you to just plug it in... PnP = plug and play. with out it you will have to hardwire into your cars computer (ECU) harness which isnt fun but can save you some money if you have the soldering skills.


good luck

id have to agree although ur going to need a better exhaust setup. So after u get emanage blue, tune, pulley and the BPV id say go grab a header and get a headerback 2.5" exhaust .. custom is cheaper so go to an exhaust shop and theyll weld a resonator in the midsection for u aswell.. then sell ur TRD for money

yes exhaust is a must if your looking to make the most power out of the trd charger. a header and full exhaust will cost ya 1k + just in it self.

a tC with the set up i recommended in my other post plus a header and full 2.5" exhaust would put down around 260whp but with out the full exhaust your probably looking at 20 less whp

here is another option is to reach 225whp:

stock trd tune
9.5lb pulley
110 bpv
header
s-pipe
catback exhaust

idk with the set up i recommended before you wouldn't have to worry about rasp or swapping out your whole exhaust. not only that but you would make more power

its been known that you can make 225-230whp on a stock trd s/c setup with just a proper tune with a piggy back unit. so if ya up the boost a bit and get a good tune im sure you could see more then the 225whp your looking for. however the stock exhaust will limit your gains.


yes there are several ways to get to where you want im just trying to think what the best bang for your buck..

btw sorry if im a little all over the place, its 5am and i havent slept yet

haha its fine bro, this is great info to hear

i heard its a pain to have to install a new header after the supercharger is already there so (tell me if this is a good idea)

basically install a new header and mid pipe with the already instake and trd exhaust for a goal of 230whp, the trd exhaust should be big/open enough right?

anyways im thinking that the header and midpipe with resinators welded in should be somewhere around 500$

get the supercharger

then spend remaining on
9.5lb pulley
Bosch 110 bpv
emanage

then wait for some more money and get a dyno tune?

is this a good route?

i disagree on the 260 whp unexpectedterror.. ive seen many s/c with 9.5 pulley full exhaust including header, intake, BPV and a tune not even come close to those numbers..

first of all props on your amazing accomplishment!


so...from what i have seen 225-240whp about right...

if you are going to get it tuned why not go with the 12lb pulley? the 9,5lb pulley can be run on the trd reflash but the 12lb pulley requires a tune.

the trd axleback is too restrictive im pretty sure its 2.25" and you should go custom 2.5" route which will probably be about $500 depending on the tip/muffler you want to get.

you can also cut up your CAI to make it work with your supercharger which will give you some more power as well.

hope that helps.

Wow. Congrats on all that you ahve worked so hard for. Thats great to see people putting in alot of work, time and sweat and gettign rewarded. Its great to see there are young people out there still trying hard and trusting in themselves and trying to make it without there parents help.

Anyways congrats on the rents gettign ya a supercharger. Defintily get a 9.5 psi pulley. I nice pair of grippy tires if you dont have them already and a better exhaust. Thats how id go. Although if you got good tires get an s-pipe, exhaust, and buy yourself a nice outfit with the rest of the money.

hey thanks alot voltage, Its suchs an over used phrase but you really can do anything you set your mind to

So like you guts know I have about 1000$ to drop on top of my supercharger-

I would like to do this on phases because of money
Would this make sence?

Get a new header and downpipe installed with resenators welded in to have a decent full exhaust setup

Get the supercharger installed and 9.5 or 12lb pully installed at the same time or us the pully something I could do myself?

Then new cat back 2.5-3 inch exhaust with dyno tune

Then emange and possible pnp harness or would that be one of the first mods I do?

Sounds good. But you definitely need to get an emanage with the 12psi pulley. The 9.5 can run on the trd tune but not the 12psi pulley. For a college guy i would stick to the 9.5 pulley for relaiability.

thats not true at all apparently everyone you have seen hasn't had a real tune. there is a guy running all of that getting 268whp with a tune. i believe he was seeing 10psi
