Obviously there has been some problems with people not increasing the fuel injectors causing the engine to blow. So i should upgrade to 440cc injectors? also =what kit is the safest for my car to install? turbonetics?dezod?zpi? also it looks like i need to get a A/t cooler...do i also need to upgrade the clutch? Id be happy with 250+ whp and eventually i want to run atleast 13.5 in the 1/4 mile. Also were do i get my ECU flashed? Any advice would really help me out, im new to the whole turbo thing and ive been doing research, so the more i know the better thanks.

 

my advice to you is prepare for the worst cause you never know what may go wrong, have enough money saved incase problems arise after your install. If your car is auto you cant upgrade your clutch, but the A/T cooler could help im not too familiar with it tho. You dont get your ecu flashed, if you opt for the supercharger i think they do somehting like that but i know almost everyone is running some sort of piggyback ECU if not a standalone. im just warning you to be prepared, im not trying to scare you from going F/I just htat i thought i would just breeze through my installation and be problem free, but i ran into numerous problems that ended up with me paying more and more money to get them fixed and im still not done lol. who knows though maybe you wont see any problems hopefully read up on this if you havent i know it helped me when i was doin my research https://www.scionlife.com/forums/viewtopic.php?t=125753

 

^^ he's right, have some extra money for unexpected things.

since you're auto, the tranny will eventually start having problems (sooner rather then later), esp. if your going for 250whp.

 

I think you should keep researching

Seriously though, the first step is having $5000-$7000 in your pocket, especially if you're going to have to pay someone to do the install.

 

turboing a auto, you can do that????

250whp be prepared to start looking for tranny upgrades or another tranny...or you can take the high road like me and do a swap

 

turbos are like women.... they need constant attention if you treat them wrong. The more name brand kits pretty much come with everything you need. A REFLASH IS NEEDED. With the increased volume of air comming in the engine.... you can have the biggest injectors on the market you wont flow that much fuel. Your computer will limit it. and you will still be too lean. Lean is mean and is what blows motors. pending on psi wanting to run going to a dealer and getting a sc reflash will be ok on stock internals. If a lot of psi is wanted rebuild your motor with beefy parts, and get a emanage system. as for your tranny. heat is the enemy you have to keep that baby cool, So a bigger trans cooller is a good idea. You can also go for some auto tranny upgrades but that requires you to drop the trans outta the car. research, research,research. if you want your turbo to be with as few hassles, let a well respected shop dyno tune it.

 

This doesn't sound right to me. I think you might mean that a management piggyback and tune are necessary. I don't think that the SC tune will help you much on a turbo setup. Turbo gurus?

 

Well i was thinkin about buying the turbonetics kit made for the automatic...and they have the unichip that piggybacks the ECU. it claims 300hp but its really more like 270hp..but id be perfectly happy with that. I still would upgrade the tranny cooler, and i read the post about upgrading the injectors because...the stock injectors are to lean with the turbo. I wont be putting to much psi prob just want the turbo does out of the box. But from im getting from everyone else..is ill be running into problems which does consern me. I just want to get everything taken cared of before it would be put back on the road..making it as hassle free as possible. And since you run premium gas and synthetic oil, how much mpg are we increasing..saying we are driving the car under the RPM that the turbo kicks in so its not boosted.

 

sigh...premium will not give you better mileage at all, and synthetic oil may give you an unmeasurable tiny decimal better mpg. Although there are some anomalous results of turbos getting slightly better mileage, it has nothing to do with 93 octane and synthetic oil.

Try it right now by using 93 and synthetic. There will be no statistically measurable difference in your mileage. Although I'm sure (like 3/4 of the people on SL) you'll probably think it's "smoother" and "zippier". That's a notion that people are so reluctant to give up, and I don't understand why.

 

sc reflash changes the a/f map enough to were, you are dumping just enough fuel to stay in that happy medium it is only good enough to run as much boost as the trd supercharger with a smaller pulley. Anything else you need a emanage.

 

one of the main problems with turboing a AT car is putting the power to the ground, and the cars inability to take on the dramatic increase in torque.....a good solution to this would be researching a torque coverter for you car, as this is the best means for an auto to get to that untapped power.....realistically, running 8.5 psi with that turbonetics kit, and a great tune (means you need to use that unichip, or an emanage or a standalone) will net you around 250 whp on average.....secondly, look into a valve body upgrade, i know zpi offered one....but for heat, possibly look into getting a better radiator, more of a race type one, which will dramatically decrease your heat....as for the s/c reflash, why would you use that for a turbo.....don't consider that a tune by any means, its meant for the s/c.....as for injectors, all complete kits come with injectors, so you shouldn't worry about that.....you need to research a ton more before you attempt this....the way FI goes is you get what you pay for, and realistically if you don't have the means to install it yourself, you'll need to save total at least $2000 on top of the cost of the kit.....and do not take a loan out for this!! lol

 

Just thought i'd chime in here since I'm a boosted Auto. Don't get me wrong its cool and fun, but it sucks that right off the bat auto guys are stuck around the 240/250whp range because of our tranny's. We have to spend a big chunk of change to upgrade the tranny, instead of being able to just buy a better clutch. I've looked into building the auto tranny and its an expensive task. If you just want a tad more umph when on the gas go for the Dezod set up, its reliable and comes with everything you need. I knew I wasn't going to race every weekend or anything so i went with the Treadstone kit. Its reliable and fairly easy to install (although their is some cutting involved). I guess in the end, being boosted is cool, but i'm over it. At this point, i'd rather have a factory boosted car and not deal with after-market kits and the issues that WILL arise. Just the nature of the beast. Go to Dezod's site and check out their auto kits. Then call paul and speak with him to see what would be best.

 

Wow lol. PureToxin are u from NY or anywhere near the NYC area? If so I can refer u to a shop that will do ur turbo install without havin to do any dumb "tranny upgrades" or "be stuck @ 250hp with 8.5psi".
I think a lot of the guys on this site are letting their shop talk too much sh*t into their brains so they end up spendin more money then they have to and make their shop rich...
Tranny cooler isn't a must, ur tranny will be fine, will it hurt if u got one? Of course not, hell u can get one for $40 installed if u really wanted to anyway. A racing style radiator?? Don't get it. U don't need one. Waste of money, but again wouldn't hurt of course to get one. Gettin stuck with 250whp @8.5 psi??? I have 260whp and I'm @ 7 psi, running overly rich, so I don't know where that came from...
Anyway it all comes down to this, don't go cheap, but u don't need super expensive either, especially with 270 -300whp, ur stock internals will hold 350whp @ 14psi. But u will have to change ur fuel pump to reach close to 300whp.

U just need a tuner who actually takes his time and cares about his customers.
Not some dude who's gonna read the installation instructions and just bolt on a turbo for u...

 

Ive seen alot of posts about tranny slippage after 250+ and it seems like its true. Ive also heard about the ZPI stage 0 turbo being great for automatic, but if you have the money dezod's is better in the long run. But if you get the ZPI do you have to do any upgrades..buy any sort of emange system for it..my guess is yes..i would just like it if some cleared it up. also what RPM does the turbo start kicking?

 

Well I'd like to know how long people had there turbo on for before the tranny started to slip (how many miles)...
Zpi I wouldn't go with because they are goin thru some legal issues right now and their CEO is no longer with them. Also they tend to go with performance rather then reliability, their kits are built cheaper.

 

As Vinnie_NB stated do not go with ZPI, you will not get your kit and then you are out of that hard earned money. They are going through some major legal issues and theres a list going of who payed for parts they havent received yet. Also, you would hafta go with some sort of management and igraded injectors anyway, a bov and an intercooler in order for the car to run safe...the turbo will start to spool if im not mistaken at around 2800-3000 rpms. Definitely go with the dezod automatic kit or the turbo toyota's kit...the 2 best quality kits out there. You get what you pay for and thats pretty obvious in the price difference of kits compared to zpi
