Hey guys i have an auto 06 scion tc....

Im starting a project to convert it to turbo...im in the process to buy a t3-t4 turbo.
Does anyone there with experience know how much i can safley boost my scion without troubling my internals??

tnx

 

not sure. but i'd assume with proper equipment and good tune, 6-7 psi, like the trd supercharger.

 

make sure you get a tranny cooler, and i'd also suggest ZPI's valve body upgrade, I currently run a stage 0 on my auto, runs like a champ

 

rather than making your own i'd recommend a kit mostly if you want a reliable.

There is a lot to go into an automatic kit so i'd just buy one from zpi. They're a great company.

talk to 318_tc....he had a auto turboed tC...but is recently converted it to a 5spd

 

This question has been asked many times, the answer is always the same "it's all about the proper tuning". I wouldn't go over 10psi with stock internals. At least not as a DD. My question is if you wanted a sporty quick car, why did you get an auto? Turbo manual car is much more fun than an auto. Auto's do hold boost better though so speedwise you might even be faster than a manual. But you won't feel the speed as much. A friend of mine has an auto 3rd gen TL, and that car is fun for about half an hour and then it gets boring. Auto+fwd=boring. Just swap your scion for a manual.

 

Well were im from there sno scion dealership
Sooo i got to work with what i have....
And i tought it would be a fun project

 

read the "turbocharging your a/t" sticky, it'll answer all your questions.

 

<-- Auto turboed tC Owner.

Get a tranny cooler.

 

<----Boosted Auto here as well. Don't let the manual guys get to ya, they are just jealous that we stay in boost thru all the gear

 

yeah, totally sucks that we can just upgrade a measily clutch to hold more power while you guys get cool stuff like tranny coolers and valve body upgrades

only a sucker would buy a car without a clutch jk

 

Actually, i'm in the process of building the Auto Tranny. I don't want to reveal tooo much but i'll just say this

500HP Auto? :D :D :D

 

dont we have an electronic clutch?

 

no, you have a torque convertor, planetary gears, and a stall convertor. no clutches. you have ECT or something like that. electronically controlled transmission. only high-end autos like bmw's and benz's and porsches and audis have automatic trannys with an automated clutch. i think they are hydralyically controlled.

 

and only some people know the details!

 

and i'll say pointless? lol jk that should be sweet

 

yeah, if the tranny can hold it, just wait for the axles to snap! should be quite a show, can't wait to see the video!

 

well of course custom axles would be needed. but this is a longterm project. keep ya posted

 

Turbo-/supercharging an auto is like tipping a waitress for bad service. Sure, it can be done, but why pay more for less? j/k guys

 

It can be done. I would try working with some of the manufacturers that have come out with kits for the auto, even if you use them as a base, there is quite a bit of knowledge you can gain.

I have an auto tC, boosted with the Dezod kit and have about 20k miles on the car since I installed it last summer.
