i would love to add some much needed horsepower to my stock scion. Im not big on the power part. I dont want to add a turbo yet. (not enough money). Would like some kind of kick. What are some ways that i could make this happen. by the way I have a 2006 rs 2.0

search is your friend, i would start with I/H/E, wont be much gain other than boost, but still makes for fun that you can do at home, everyone here is all about boost so there wont be much help beyond that

I/H/E is really the only route like the other guys said, unless you want to go all motor. you dont have the potential of a turbo but you wont spend $4G's right away...eventually mabye.

Dont buy reall expensive I/H/E, its just a name. megan racing is cheap. check out hopupracing.com (free shipping) as for intake, i advise short ram. like i said before, dont go expensive. i got the cheapest and im just like the other I/H/E guy. Im stationed in guam and its not good conditions for a turbo so im waiting till i get back into the states.

for your exaust go to napa/autozone and get ALL NEW GASKETS, and go to ace hardware or something of that nature and get nuts, bolts, and washers. get the same number the same size (GET GRADE A IF POSSIBLE)

enjoy...:icon_biggrin:

Wow...just......

You know for a good IHE setup you can practically get a used turbo kit right?

Save your money.

And seriously...search..this sorta ____ is discussed all the time.

nitrous is the most low cost per power output
next would be turbo

It'd be a waste of cash and effort on IHE if you are saving for a turbo;
The only thing worth your trouble is exhaust, and even that won't be really worth ish until the turbo is in.

Wow....funny site.

I love kalecoauto..... helped me get my car to where I want it..... its legit

I/H/E pullies probably 180whp not even but youll feel a difference......and check out the TWP ajustable throttle controller here on scion life it makes the car pull harder

tune the car with greddy ultimate with no mods. you can gain from tweaking a/f ratio, timing and make the fuel map more responsive.

The stock tune is already efficient for an N/A car with no mods. Doing this would be a total waste of time and money.

I/H/E wont get u 180whp lol... mostly 150-155whp tops.... i know because my buddy owns a shop and i dyno my car with every mod i get and i have yet to pass 150whp on N/A.... i dont have a header but i assume it wont give me 5+whp

there is a dyno sheet on here of someone with a stock 07 tC and If i remember right it had 154 on a dyno. Thats not bad. So wth an intake, header, and exhaust I see 160's. then there is a vvt-i controller. Maybe 170's....maybe. Pullies would help too. With that all said and done I would say around 170-180hp....on the dyno. Of course the i/h/e set up would have to be the best of the best. And your going to end up spending some cash. So why not go turbo? when all said and done with a turbo its expensive....but why would you spend say maybe 2k on bolt-ons only to start saving again for a turbo kit?? Would be better to use what yo have on parts now....say if a discount comes up....used parts that are still good etc.

the stock tune is built for emissions. the motor actually makes more power from the factory, but it gets detuned down. wot is in the 12's a/f. i can tell you from fact, that you gain more response from tuning than bolt on's. i own all of the above and tuning would have been my 1st choice now.

I didn't doubt that you could get the car to be more responsive or squeeze out some horsepower with a tune, but a tune on an N/A tC IMO isnt' really worth the time or effort.

I can't imagine the car gaining even 10whp from something like that..not only do you have to buy the greddy ultimate but a wiring harness as well..so new you're looking at almost $1k no? (correct me if I'm wrong but that's just what I've seen).

If tuning an N/A car with no mods was that efficient in terms of HP to cost then I honestly think more people would do it.

off by 7whp lol.. but its still no 180

stock tC is 145whp. Not getting 35whp from IHE and pulleys. Maybe 165whp to 170whp with ALL of that on a perfet day.

How come nobody ever mentions that '07-10 has about 8 to 15 more horsepower than the '05-06? That's the reason for the confusion about these numbers.

eh?

eh?

I dont think thats true. is it? Im pretty sure its the same engine and everything. 160 hp 163 tq.

07-up have oil squirter's. i think have slightly different compression than the previous years but i could be wrong about that.

ptuning said when they dyno'd their turbo kit on different tcs they saw a 15 hp difference between 05-06 to 07-up

I dont think thats true. is it? Im pretty sure its the same engine and everything. 160 hp 163 tq.the way all car builders would dyno were different, so they made them all use a certain more strict method. this caused everyone to bump up thier horsepower or lower thier advertised #'s. that is why 07 and up got a bump in mods and power.

i have an injen intake, mmw header (supposedly the best out there) and trd exhaust... minimal gain for me but it does kick a bit more, what do you think about the whole port polish, the stuff dezod does where they clean the heads and all they add hp right?

A P&P on it's own, again, isn't worth it without supporting mods (i.e. built motor or turbo or both) you will see some gains for sure but P&P isn't a cheap thing to have done..as far as I know anyway.

wow lol arguing over bolt-on engine peformance just save your money man turbo or bust w/ these cars you can get a used kit for 1k to 2k off the classfeilds

lol, maybe when comparing two boosted cars running the likes of a PTuning kit @ 12psi, but they dyno the same in stock form and they both have the same minimal gains from I/H/E.

not everyone takes the easy road in life. knowing how strict emissions and police crackdowns are, you got to make it reversable quick.

yeah sucks for you in Cali here in NC they can care less about emissions im almost done with my build should be end of summer.i'm not taking the easy route thats the only way to get any power out of the 2az is boost

OP get a street bike. :D

No it's not. Car runs into the low 12's and dips into the 11's A/F ratio at WOT. That's what you would run if you were boosted, not NA. It needs to be in the high 12's to mid 13's at WOT in NA form. I should know, I tuned it that way. I already had my Ultimate because of my previous turbo. In between turbo kits, so I just left my Ultimate on the car until I purchase my PTuning system.


And FYI....the 07+ tC has a slightly higher compression, thus seeing a slight gain in HP on the dyno. 9:6.1 for 07+ vs 9:5.1 for 05-06.

ok so I was wrong lol I'm just going based off of what I was told.

best advice yet

Bboooossssssssstttttttttttt!!!!!!!!!!!!!!!!!!!

ok so I was wrong lol I'm just going based off of what I was told.


It's not biggie, I mean it's only a slight street tune for WOT. Also, I changed the way the car transitions into WOT (closed loop into open loop). If you stuck a wideband on a stock tC, you can watch the A/F ratio go from 14.7 (normal), and then it goes lean to about 15's/16's and then starts to drop down to 12's and eventually 11's when you get into the 5k+rpms. This is super slow compared to what I did to the tune. I made it to where the car wouldn't dip down into the 15's/16's before making it's way back to 12's/11's. Instead, now it's more like 14.7 - 15.0.....13.5....12.9. I kid you not it's like the car hits Lift/Vtec the way that it's tuned now. It's like whaaammmm...WHAAAAMMMM and not...wwwwwwwwwwwwwwwwwwAAAAMMM. The stock tune is more low reaching down low and gradual build up, vs what I've done to it now.

To put into perspective. I guaged this via real world means as well, by having my boy Slikk race me in his 08 tC. His 08 has a Injen CAI, and I just have a full exhaust (stock header, stock airbox), since buying those things would be worthless because I'm going back on boost soon.

We raced and he would pull about a half a car to car on me before the EU tweak. Granted I have drag holding me back since I have an APR front splitter and APR GT200 wing. So, I went home, flattened the wing out some, and then I began to tweak the EU. We re-raced on another day with the tweak to the EU. I pulled like 3 cars on him with both of us starting in 3rd gear at like 40mph.

The other benefit to this is that the EU has the ability to increase your redline. The 05-06 tC redlines at 6250rpms and the 07+ redline at 6500rpms (this is another reason why you might find a slight increase in HP on the 07+, they simply have more compression and a tweaked tune to go with that bump in rpms). Since my tC is an 06, I changed the redline to that of the 07+ (6500rpms). Great benefit for 05-06 guys to be able to shift at the same time as the 07+ guys.


FYI...tC can effectively rev to 7k rpms without work to the head. On a completely stock motor, I would not put no more than 6800rpms to it (to high for NA but good for turbo), and if you have a built bottom end and turbo but with stock head, It would be fine to take it to 7k.

07-up have oil squirter's. i think have slightly different compression than the previous years but i could be wrong about that.

I'm pretty sure you're right, oil-squirters, slight raise in compression and a more equal-length exhaust manifold. They changed the way they measure SAE crank horsepower around 2005 or 2006 I think? This may be why the '07+ have a slight bump in power, but they are rated the same at the crank. Could be wrong though.

bolt ons add almost no power

turbo is the way to go for sure

BOOST BOOST BOOST! Used kits are usually a steal on here :) Before you start slapping money into this car know WHAT you want your goal to be. My goals are laid out and I started with the internals. No huge gains yet, but after everything gets put together it will be well worth the wait.

If you are going to boost dont waste your cash on anything else yet!

I don't know why you N/A guys don't listen to this man. The reason why I got my ultimate is because his input and knowledge.

Oh yeah, true that. Mixed up the compression ratio. Indeed 07+ has 9:8.1 compression.

just get all bolt on's and the greddy ultimate and a lil 50 shot and call it a day if u don't want turbo....

should've gotten faster car? :lalala:

should've gotten faster car? :lalala:


i bought my tc all stock im in the 350-400 range now so it's not really about buying a faster car.. look at the civic's

should've gotten faster car? :lalala:


Naw just need a proper turbo setup.

You are correct in all three categories.
Thanks, haha. Good to know.

moral of this thread bolt-ons equal riding failboat turbo equals riding the spoolbus and making power lol

Spoolbus is new...I likey!

Na, dump the turbo! Strap on a good jet engine! Problem solved, then you will never have to worry about anyone having more "pony power" than you! I'll get ya a good deal on JP-8 to!

nitrous is the most low cost per power output
next would be turbo

It'd be a waste of cash and effort on IHE if you are saving for a turbo;
The only thing worth your trouble is exhaust, and even that won't be really worth ish until the turbo is in.
R


Yeah...but keep in mind that its also the easiest way to literally blow up your car (Nitrous that is).
And you'll be lucky if that's all that dies that day. I've worked on custom cars for many more moons then I care to admit to.... and IMHO...on a drag strip with professionals is the ONLY place that belongs.
