Ok im getting more and more pm's and im seeing more posts about turbocharging an a/t tC! Let me clairify somethings.

1. ZPI and Dezod both have kits avaliable for the tC.(waiting on conformation from turbonetics)
2. Greddy kit will fit the a/t tC but you need to get the optional fuel upgrades!
3. If you try going the cheap route you will blow your engine!(ask g0t_rice)
4. The a/t tC needs larger injectors! at minimum 410cc's the a/t tC for some reason requires more fuel then the m/t if you do not upgrade the injectors and have emange to tune you will max out your injectors and in turn see # 3!
5. For the love of god spend $40 and get an a/t cooler! $40 thats all shipped from Summit Racing!!!
6. a/t tCs will need a tune! im sorry thats just the truth!

so to recap; UPGRADE YOUR INJECTORS!!!! Have some form of fuel managment to tune your car! and spend $40 buy an a/t cooler! anything further don't hesitate to pm me. :D

 

does anybody's kit work with factory fogs?

 

Great info there! I was gonna go the cheap route and not get management for a while but I think Id rather wait a few more months to save up for the Emanage rather than wait a year to save up for a new engine. AT cooler has already been installed but I want to upgrade that to a B&M. Which one are you running?

 

Excellent advice because i was planning on going the cheap route (i'm a college student, it's my nature).

 

im so wishy-washy after looking at the ____ poor numbers of the auto supercharger dyno... auto that hits 250, its all i want. I am just wondering why the zpi turbo is cheaper than dezod and has better gains... turbos confuse the heck out of me... ugh

 

Gosh... Nothing a little search won't tell you.... Might as well sticky this for a bit, as it won't go away....

This is discussed multiple times, but Let's keep it stickied, so at least for the next few months I don't need to lock threads about all the reposts....

 

awww come on... i have been on these forums for a year and a half. that is the first time i have been accused of not searching. what i get is SLANTED reasoning. thanks for stickying this as I would like a one-stop-shop for my questions on this. can one of the more veteran posters explain what is encompassed in the safety vs power comparison?

zpi promises 230whp at 6psi
dezod looks like 220 something at 5 psi at $1000 more, but it seems like they guys over at dezod care a lot about keeping your engine stable.

my searches do CONFUSE me. there is a lot i do not understand, which is why I hope this sticky becomes popular, and I can get some answers.

(WeDriveScions, this means you! hehe)

 

Thanks for making it sticky, it can get frustrating having to search through all the scattered info on this topic.

Sorry for being a noob, but where can you get the 410cc fuel injectors? Google isn't giving me much love.

My main thought behind getting a turbo (I was looking at zpi stage 0) was to save money over the supercharger but it sounds like these additional parts could make it the more expensive proposition.

 

I second this. Not that I wouldn't give them up for more power but I like how they look.

 

^ ZPI stage 0 works with the fogs no problem... it's the FMIC that obstructs the setup.

 

good lordy ok the offical saying here in the tC f/i section is you gotta PAY to PLAY!

 

what FMIC do they use? I really have no interest in buying from ZPI after all the bad press they got.

 

Ok now then(sorry i had to change computers!)

Heres my experience.

I got the zpi stage 0.5 from a guy who was selling his, I bought it from him and installed it and it did ok. I proceeded to get an emanage and go to have it tuned, I get take it to my local tuner and he plugs it up barley gets one pull on the dyno and the guy looks at me im like wat? he tries again and same thing. He then tells me your injectors are maxed out I cant do anything if I do your engine will blow you need larger injectors and a fuel pump im like CRAP! So I put a call in to my buddies at ZPI I talk to Kenny, not having really worked with a/t's that much he said he did not know and was being honest. I told him what my tuner told me and i'm assuming at that time is when it was figured out that a/t require more fule then a m/t. So he sells me the 550s and the fuel pump but tells me its really not required since im not running high boost or larger injctors. If are still skeptical if im telling the truth PM or AIM g0t_rice and ask him he blew his engine becuase he maxed out his injecotrs and never received a proper tuning. I rode around for awhile with no injectors and no tune but my afr's were 10.0 FLAT! which is bad!! I then got the 550's in from Kenny and was dumping fuel like crazy! I was averging 16-17mpg. Kenny then came in to tune and I now get anywhere from 22-26mpg! I'm sorry but id rather see you guys safe then sorry, I dont want to see a whole buncha threads popping up becaue you blew something in your engine all because you wanted to go cheap.

 

ZPI uses the 16g turbo which comes at a lower cost then the t3/t4 turbo. Now before you start going ohh god they are going cheap blah blah blah! NO! these are the same turbos that suburaus upgrade too and are used in mitsus! The turbo I have has ehh probably about 50k miles on it now and its still kickin strong. The 16g Spools alot faster then the t3/td I believe if im not mistaken which is why it produces higher #s. What most people have to relize(and it took me awhlie to grip this) is that the a/t is WHOLE lot differnt then a m/t so the #s will never be the same. Itll cost more and take a bit more to acheive the 250whp for an a/t then say a m/t. The kit I have when it was the 0.5 put 250whp. When I orginally installed it on mine I got 215whp, when I put the injectors in becuase it was dumping so much fuel my baseline was like 168whp,wth tuning I gaind 54whp and about 6mpg roughly.

 

WDS, can you put the graph you made into my first post so we know what #s people are putting down since this will be a sticky.

 

wow, thanks peteyd, thanks for the response! I have a new question, to play devils advocate... if the t3/t4 turbo is more expensive than the 16g, why does it spool slower? in other words, what are the advantages of the t3/t4?

this was a pipe dream months ago, but now i have 2000 cash saved up. I was going to go belt blower, now I am realizing that turbos are not that scary thanks to mostly peteyd and this thread... KEEP PREACHING INFO BOYS!

 

and i believe that even thought this is a whole different animal than the manual, even with injectors, and tuning will STILL be cheaper and produce better numbers than a supercharger.

the question is "is it reliable" i am depending on a tune from a non-toyota representative. pardon me as i am a first time tuner, and going in deep, but this is scary stuff...

(i am going to be the bad guy of this thread)

 

Im not sure on the specifics of the difference between the t3/4 and the 16g the companies themselves will have to dabble that.

But ive been boosted for almost 10k miles now still aveging 23+mpg! if you want to be safe, purchase 440cc injectors and get the trd flash done with the ZPI stage 0.

 

Well, Hell... Finally someone other than me is saying it -A/T tC EAT fuel like crazy at the tail-end of 3rd gear. I've seen it time and time again on my A/F data loggs the stock 370 cc injectors cannot keep up with the ZPI Stage 0 turbo kit - even when using e-manage to force the stock injectors to run at 100% duty-cycle the A/F's are still climbing. Now when the tranny shifts to 4th gear the fuel requirements drop until you get to red-line again...but at this point you're going like oveer 100 MPH -Which is not an every-day thing at least not for me.

I love my Stage 0 on my Auto tC and would reccomend the kit with the appropriate supporting hardware to anyone -but I still see SL folks saying that the Stage 0 A/T tC does not need egine manaement and/or larger injectors -That is just not accurate information anymore. People wake up!

I've got an e-manange fuel map that appears to work good on the A/T tC on stock injectors but it falls short when you push the engine hard in 3rd gear because of the injectors. I'll post it later tonight.

 

good deal E!!
