Ok well I've had my tc for 3 years now and slowly I have been doing work to it. Now its come time for the fun stuff more hp. So far I've done the suspension; trd springs, struts, shocks, and strut bar. Also hotkis sway bars an ingalls torque damper etc. I've been working from the ground up. In two weeks the trannys getting done. lol. I just realized how funny that sounds. Im upgrading the clutch, add a light weight flywheel and limited slip. So with that said what to do next. My car is a daily driver and it needs to be reliable. I dont have another car right now so my car has to work. Im pretty handy a smart when it comes to things but I'm not a master mechanic so I'd like to know what you thing the best hp upgrade for me would be. I drive on average 65 miles a day and its mostly city. On top of that I'm not looking to dump 10k in the car just want to make it fun to drive and i'd like not to loose to hondas, especailly stock ones lol.

 

get a turbo. anyone that tells you otherwise is retarded.
the supercharger doesnt give you much hp unless you really up the boost on it. and it still doesnt make max boost til high rpm
nitrous is only fun when you hit it and isnt exactly the safest thing if youre not tuned for it (which i doubt you will do)

Whatever you do, just do it right. Dont cut corners.

 

i couldnt agree more with ^^. just get a turbo kit or put together one and im sure you will be pleased.

 

To be honest, you'll have to spend half of that 10k to get a setup that is reliable and easy to install. The PTuning kit is amazing but you are looking at 4.5k + gauges etc. It looks like you already have the supporting mods being done except motor mounts but if you use the ETD then you should be OK for the time being. Nitrous only sucks, the supercharger is officially dubbed "The Fail Snail" so your only route to beating Honda's is turbo. The PTuning kit will put you around 270+ whp at 8.5 psi. That's enough to take out a few V-TEC goobers running around.

 

I've had gone both routes, turbo - Dezod S1 and nitrous - Nytrex Triple Threat, anyone that says "nitrous sucks" please no longer listen to a word they say and put a pole between them and your car.

It is no more dangerous that the other forms of FI. If installed correctly, and there is no degree of tuning necessary at all, will run perfectly. The only downfall are the nitrous refills; I know people that run through a bottle once every month and I know people that go through them once every 2 weeks. The refills can go from anywhere to $25 per 10 lb bottle to $50 for the same bottle. It depends on your location. Even with nitrous it'll be wise to invest in a wideband AFR and a few other safety mechanisms such as the Dynotune electronic RPM/TPS switch, I can go into more details if need be.

With various bolt-ons and a 75 wet shot you'll be looking at about 220whp/245tq on a conservative dyno sans dynojet. Those are about the numbers my tC put down on a Mustang Dyno.

Easily more hp that the supercharger and about where an auto tC w/ turbo @ 5psi is putting down as well for way less money up front, refills will determine if that holds true for the long term.

Then there is the turbo option that will easily cost you $6k and that's being conservative with a lot of things. It will also cost you much more time. If you're still in school, like I am, I would recommend waiting until the summer or winter breaks to do it. You'll need a lot of time. You can also opt for a used kit that would cut the cost of everything down to roughly $3 - $4k. I would personally only look at the Dezod kit used simply because you're not going to find a Ptuning one. With the turbo there are clearly no refills so in the long term it may work out to your favor and on 8 to 10psi you are very close to 275whp....somewhere in that range +/- of course.

My tC is also my only car and my DD.

In the end it depends on your budget and what you're trying to accomplish.

 

well ill give u my input...

like ecko said... anyone saying nitrous is worthless is stupid....

nitrous is very safe if u know what you are doing.... I had no clue about cars recently, but did alot of research on nitrous... got a ny-trex triple threat kit and a dyno tune window switch....

well, after a ton of messing around to get the window switch to work, i sent it back and found out it wasnt working.... which would explain my long hours of frustration...

so now i just run my nitrous regularly... and dont even have the feul safety switch installed because you wont ever need it.... all u have to do is follow the jet sizes they list for the shot size u want, and they are already listed conservatively to make sure nothing goes wrong... just make sure u have no leaks ( i had a fuel leak in my line making me run rich) and you are set... get 1 step colder plugs and use premium gas.... take it out for a run... pull over, check ur plugs... you'll be fine...

nitrous is a TON cheaper than turbo... and nitrous is more power than the supercharger...

like ecko said... the refill varies... im lucky and only pay $26 per 10 pound tank... find out what your local best prices are.... but my vote would be nitrous as turbo is just way more money, and way more maintenance/stress on the engine ... tho thats why it gives u the most power too

 

Plan on getting this within the next month.

IMO for a daily this is the best way to go. Your not always using it so when you goto work everyday you won't be putting the strain on your motor from turbo or sc.

 

My vote is to a turbo
with a lot of nitrous bottles u can get up to 150hp...maybe. but with a turbo you can set up the boost to about 15lbs and make way over 150hp. On the dezod S1 kit on just 5psi you typically get up to 50hp, and 8psi you typically get up to 80hp(this is all assuming you have a pretty good tune).

This is a snippet from dezod.com

The critically acclaimed Dezod Scion tC turbo system is not only the subject of attempted copy by many, but is the subject of envy, and has never been duplicated. The real performance value of the system lies well within the design of the units, and how they function together as a whole. The whole Dezod Scion tC turbo system was tested time and time again for the upmost relaibility. While on the topic of whole, did we forget to mention that we include a plug-n-play engine management system and fuel injectors, which means NO WIRING or worrying for you. Just drop in, fire up and get to enjoying your investment! We do not exclude parts to lower the price of our turbo systems, and there are no smoke and mirrors here. What you see, is what you get. No extras to pick-up to get the kit running. On to what you crave the most........POWER:



We have seen vast results come out of this system from 240whp to 270whp on the preset boost level of 8 PSI for manuals and 200-235whp on 5 PSI for the automatics. All of which have also had a very nice TQ figure close to it as well, which makes it a fast kit at any gear and any time!



The S1 turbocharger is virtually lagless, so there will be no need with trying to worry about keeping up with your friends' T25 turbo. The S1 turbine and compressor wheel arrangement where dynamically spec'd for the Scion tC turbo by the Dezod engineers to provide utmost efficiency, decreased spool up and expandable power to 350HP! Like much of the kit's construction, it was designed with expansion in mind.

Thanks guys. The fact that I use my car all the time is why I've been leaning towards nitrous. You pretty much only use when you need to and it's a lot lower mantainence then a turbo. I have a hook up for refills and I would pretty mush only use it when necisary. I was thinking some where around a 50 shot just to be safe. I just hate loosing to stock si but i drive around the city so much a turbo mostly be a waste of gas to me. Oh and I always run super always have. So any more info on nitrous you can shoot my way is aprecated or where I can research on it so I have an idea of what Im doing. thanx all

 

another vote here for nitrous, been running the nytrex triple threat kit and havent had a problem yet!

 

No, need to quote an entire website, just post the link for goodness sake.

No tC with nitrous can run a 150 shot; it doesn't matter what they did to the motor. The most you can run is a 100 shot but that will max out your injectors and bog the system. Since the factory fuel line is return-less; upgrading the injectors and fuel pump will help minimally. The best best on a manual is a 75 shot for nitrous.

The tune itself has little to do with hp unless it is just pig rich. It is more so for reliability which everyone wants and drive-ability which is why everyone with a turbo wants to get tuned. If you are looking to squeeze power out of a tune your tune becomes very hot and risks detonation. If you go to a tuner and he tells you he'll get you the most hp possible, get back in your car and drive as far away as possible...that is asking for detonation.

 

So I need to dispel some myths....with a good tune you get more MPG with a turbo than NA; just ask CarbonXe how he gets an average of 28mpg running 11psi.

Next, you losing to a stock Si is because you haven't mastered driving a stick yet; once you do you can beat Si's everyday.

So you run super and you have no mods that require it....your car asks for regular, use it, you are not gaining anything but wasting money by using super premium, simply use quality gas....not Uncle Ben's Fuel.

There is a ton of information on nitrous available here, just search the forums or search posts that i've made and it'll lead you straight to it.

You'll have fun with whatever option you choose then you'll have a reason to use that super premium.

 

I can drive trust me. I havent lost to a tc since I've owned my car but if you put two comarable drives and ones in a faster car they'll take you ever time. I've beaten a type s but lost to two si's zt the top end the always seem to catch me cuz they're car revs higher. After third I have nothing on them.

 

Oh and even with a good tune you're not going to get better gas miles with a turbo in the city. On the highway yes cuz of the consistency of your rpm but when your constantly stoping and going it would waste more gas. oh and I've always used premium. I plan on keping my car and they're are long term benifits to using it and I also get better gas milage with it.

 

i have an auto and am running a 65 shot on there and the car takes it like its nothing... i am thinking about going up to a 75 shot and staying there... your car will laugh at the 50 shot... you are perfectly safe even at 75
