If stock 5 speed tc puts down about 140hp, what kinda increase would you expect from ...

- injen cold air intake
- megan cat back exhaust
- invidia s-pipe
- NST 3 piece pulley system

id love to add 20 rwhp but not sure if that stuff would add up to that

that stuff adds up to about 1000$

scionlife has this awesome feature called a search button that will probably pull up about 1000+ threads on this topic. I'm sure at least one of those can answer your question.



Oh and by the way, the tc puts power through the front wheels. :loser:

haha dur i knew that lmao ..... i had a camaro for 6 years im just used to saying it ....

umm searching hmm i did find injen intake puts about 8 hp ...

keep searching, grab a calculator, and add it all together. then repeat this process next time you have a question.

wow harsh : (

Guys get over the fact that hes asking a question someone else has. Did that ruin your day? Bro to answer your question your probably looking at +8-10 whp for the pulley... +3-5 whp for the intake...+4-6 for the s-pipe and around +8-12 for the exhaust (as long as its catback) Add that all together and your roughly looking at

23-30 (give or take a few)

Thank you : )

that sounds pretty damn good to me.. definitley worth the 1000 for around 25hp

With those mods you might have a sweet sounding tc, but imho 23-30 is max unless you get a header. Which im pretty sure adds more hp than the exhaust or intake.

ahh ya actually I was forgetting the header. those numbers are based off a header too. Sorry bro when I think exhaust I think header back. Because thats the TRUE full system. Even tho your s-pipe and catback will give you a full system up to the header... the stock restrictive header along with that fatty cat converter is still going to bottleneck your system a bit.

yeah, i have almost all those mods plus a header and im about 22-25 over stock you can def feel it in the first 3 gears from 3500 to 5500

your page says you have intake, axle back exhaust, one pulley the crank, headers yes, but your s-pipe in a box meaning not on car right.

thats different than the 3 pulley set, cat back exhaust(+ midpipe) and s-pipe instaled, + intake

basically im trying to find out is it worth 20 hp ......

3 pulley set
megan full cat back ( midpipe)
invidia s-pipe
injen intake

The headers i was thinking about getting but i dont know if i wana get rid of the cat and have to deal with the whole defowler throwing codes stuff

hmmm maybe megan headers added to those 4 for the 20 to 25 hp

will this from weapon r solve all code problems

http://weapon-r.com/english/index.php?main_page=product_info&cPath=7&products_id=6219

it will but the antifouler mod is cheaper and fixes it as well most the time

the s pipe is on now, and the 3 pulley setup isn't worth that much of a difference, the crank pulley is the biggest one for results, you might gain .5 hp from the other two pulleys. and if you look at the parts im running, its all the best stuff, check out the dyno sheets on the parts round up thread, the alphawerks header is the best, the injen made the most, and aside from that little bity cat on the stock midpipe, our mid pipes are built really well and everyone will tell you that a full catback doesnt gain you much more over a decent axle back. there again a mid pipe might show gains of 1 -2 hp. so why spend the money if not needed. the header and s pipe are the two biggest draw backs from the stock system. thats why i said i basically had what you were looking for, not exactually, and i dont have a check engine light on, i did the anti fouler trick and it works

so for the best bang for buck your saying ....

megan racing headers
invidia s-pipe
injen cai
underdrive crank pulley

that stuff would run 650 bucks ...... thats gotta be about 20 hp more

and some type of axle back, or the megan drift spec catback. the megan s pipe also is just a little cheaper then the invidia and they produce nearly the same numbers, plus i think most places are still out of stock on the invidia. the megan header makes good hp numbers but the total spread isnt that great do to the quickness that it turns from 4 to 1, a dc or someting like i have makes overall more power and torque cause each running is longer and allows the exhaust to equal out before being collected and sent out the muffler. check out the part round up thread, youll see what i mean.
the alphawerks is no longer made, but there is a company that makes one just like it and for a good deal. ill search and when i find it ill post up. but theres a thread here about that as well

the header is made by dme

heres the thread on it:
http://www.scionlife.com/forums/viewtopic.php?t=201275&highlight=

believe me, i had a dc on at first, nice header but the one thing i noticed was the sound, the exhaust note was real rasp and you could hear the motor under the hood, as if the header tubes were to thin, when i replaced it with the alphawerks the exhaust note cleaned up and under the hood sounded like a stock car again, still had a little rasp, but then i installed the s pipe and now its just sounds really throaty, very little rasp with the s pipe on, thinking about doing the resonator trick and see if i like that. and with the pulley youll love how much faster it revs :P

first let me say NEVER add up the horse power given off a website advertisement cause its complete BS. your doing exactly what they want you to do. You may get 5hp a mod

^^^ Very true. To figure out how much HP you have gained, you would have to Dyno your car. Search the site for similar setups and you can get an idea of what you might have.

members here dynoed injen intake and it got 8 hp

alright guys, with those mods i doubt you will gain 20whp.

first, you MAY gain that much at peak hp, but your bottom end will DIE. so, you just took hp from another part of the powerband and shifted it to your top end.

second, your methods of adding the whp are incorrect. besides the fact that your #'s are inflated by a few whp per item, you are adding them on top of one another. that's not how you do it. for example, if i proved on a dyno that an exhaust yielded 5whp, an intake 5whp, and pullies 5whp, i would not gain 15whp total. it would probably be more like 11-13whp.

lastly, it has been proven time and time again that our cars are already very efficient in terms of airflow. you might gain a lot of whp with those mods on a '95 civic, but with the technology on our engines today, you won't see it.

your car will sound meaner and may have a bit of a fatter top end curve, but you will sacrifice the power in other places. therefore, your car overall will not be much faster.

$.02

This is true that you will not see the gains you have seen before on the older motors...HOWEVER...Having a full header back set up ( includes deleted cats) along with intake and pulleys you WILL see 20+ hp...sorry but you will...you will also notice a good torque increase.

here is the average gain with those parts

140 Stock whp

to

at least 160+


90% of the people on this site with those mods are well over that mark.

well i never got to stock dyno mine so i have no clue the exact gains, but im around the 164 mark now and that was before the s pipe was installed and the outside weather around 76 degrees, lets say i made 146 which i have heard some stock ones making, with the s pipe installed and a new set of plugs i should be right at 20 whp!

^^Well not with just the s-pipe lol. Personally I am investing in a trunk monkey :rofl:

of course not just an spipe....but everything else and i think i want to run a dfferent plug, car only has 18k on it but its starting to feel like its running alittle rough at idle, i know with the upgrades the ride and sound wont be the same, but whats 20 something bucks for a new set of plugs?!?!?

Do you have an ETD?

ummm i looked at the roundup testing for cai, header, axleback and basicly power was increased through the whole entire rpm range ... just the very few first 500 rpms it had a drop maybe

ok well install these parts and see for yourself how much low end torque you loose like myself and every other person that has

I have noticed much better launches myself with my current mods. still have a ways to go tho as I just started

what does better launches mean? you can easily spin your tires through 1st gear on a stock 5 speed tC with a decent launch.. if your launches are better now, you must be losing some low-end torque... either that or you're launching in fat midrange RPMs, in which case you're already spinning your tires.... and isn't a better launch.

i'm not calling out your claims, i'm just stating my opinion. i tried the bolt-ons approach at first, too. i noticed a not-so-nice low end drop off, and IMO any gains i may have had on the top-end weren't worth it... hence i went back to stock and then TURBO'D!!! :P

TURBO FTW

with DC Header, AEM intake, HKS Hi Power axle back in 94 degree heat i got 157 whp

basically what im saying is...

when i put my foot to the floor.. I noticeably felt more thrown into my seat then stock.

yea hes always posting his opinion on how its a waste of money for bolt ons ...

To me it seems like its worth it from every single dyno and 1/4 mile run ive seen with I/H/E/ + - pulleys

20 + hp to the wheels for 1500 seems pretty good when car only has 140 and costs 17,000

Do you have a before/after dyno for an intake, full exhaust + header, and pulley setup? I searched but could only find dyno plots for the individual pieces.

yea not too badd
