turbo with auto isn't that bad, just don't expect big power unless your going to build the trans or swap it out to a 5 speed.

intake, exhaust, headers is perfectly fine with some weight reduction and suspension you'll be good

if it were an 05-06, i'd have said look into the TRD supercharger, it's only 2k compared to 4k for the 07-09 tC's, and has an auto fit kit, is good enough for power and would be covered under warranty.

i've got an '06 auto tC with intake and exhaust, but most of my money is in the car for looks and functionality, wheels i liked, an audio system, etc..

Dont put alot of money in performance, other than an intake and maybe an exhaust ... these cars have no potential and were never intended to as far as performance. Just add some lowering springs, rims, lip kit and youre done. Save the rest of the money for a bmw or a benz.

Tell Chris Rado that after he beats the crap out of all that EURO trash. Simply put, VW, Benz, Audi, and BMW are backwards engineered and require piles of money to gain a little power and simply maintain those overpriced POS.

Anything can be made fast and Scion's potential hasn't even begun if you look at how much has only ben done in 4 years....wait 4 more and just see!

The ONLY forced induction thats worth it for an auto is a supercharger. The tC can only take so much torque before all it does is just spin its tires because it has no limited slip.

Since there is no limited slip for the auto, once you go boost you will lose a lot of traction after a certain point so your pretty limited to how much you actually can boost.

On another note - the auto can't handle a lot of power before it starts to slip and that is a costly repair.

Personally (as someone also with an auto) after the research I have done, unless they somehow come out with an LSD for the auto, the supercharger is the best way to go.

Bottom line - without the LSD you are pretty limited as to what you can do as far as boost goes.

This is just my own personal observation after doing my own research and so on, if anyone wants to correct me feel free, but I feel the biggest weakness in the tC is it doesn't have an LSD.

There is a company, reportedly, that is working on a LSD for an auto transmission...or similar to one. I wish I could remember the company or the source for you.

The difference between the two trannys stock isn't that great. Everyone says that you shouldn't turbo an auto because they suck anyways. They really aren't much slower, for our cars atleast. Zero to sixty in a auto tC is reportedly roughly 8.4 seconds versus 7.8 seconds for the manual with good shifts. This isn't bad for the tC, there are other cars, the Neon I believe is one, that have 3-4 second differences. Given that there human error in shifting a manual, an auto could beat a manual off the line, if you aren't shifting when you should.

That said...our tranny in an auto still is said to slip at 250 hp...if you really push it. Minor tranny work would allow for more boost. Its not ridiculously expensive, but not exactly cheap either. Weigh out your options. If you aren't going crazy, an auto tC with low boost is perfectly fine, and the route I'd probably end up going. Even better with the right tires, if you are worried about traction.

I myself would prefer a turbo over the supercharger, in my mind, cost for cost I see more benefit, and potential later if you so wished, out of a turbo.


...this is probably one of those topics though that like religion and politics, no one will ever seem to agree on.

I want to get the most out of it but paying for a turbo that I need to use at low boost seems weird but so does buying a supercharger that really does not come close in power. It does seem that a turbo would make more sense but is it worth it on a auto, thats the big question.

5-10 psi boost isn't bad. If you have the cash, and the drive for a little fun...it's worth it, I'd say. It doesn't need to be a 500hp powerhouse to be worth it and have fun. I mean, it really depends on what you want out of it, where you want it to go, what you intend on doing to it...or with it...if you intend on racing it, or just having it capable of having that power when you want a little fun or surprise some of the other guys your age driving more expensive cars....

So, is it worth it to you? What's the game plan with it?

Really just for some fun not really racing. I think its pretty good idea but anyone know of the most reliable and recommended turbo kit? Anyone have any experience with a certain brand and what is the price on the one you got.

try TurboToyotas Basik kit or the Dezod S1 kit.

the TT kit is definitely the cheaper kit and I think was originally built with intention of going into an auto?

and the dezod kit has just proven to be a very reliable kit

Can't really go wrong with either one IMO. Don't think i've really ever heard about those kits failing.

As far as reliability goes I've heard more problems with the s/c than either one of those turbo kits. The main thing the S/C has is the warranty

Save your money since you are ahead of the game with the car being a gift. If you decide you like the tC save it as a trade in for a manual tC if you want to go performance.

I've read of ____loads, pardon my french , of problems with the supercharger and of pretty poor reliability. Cheaper is about it's only benefit in my opinion, and still not by that much.


*edit* It goes without saying that warranty is a given plus, ofcourse....Though I just said.

I have an 06 auto and I have been turbo'd for about 9 months and I LOVE IT!!!! I used the ZPI 0 kit at first. If you are looking for a good kit for an auto that would be it. With its small fast spool up turbo. The stage 0 is nice because there is no modification that is needed at 6 psi like FMIC, piggyback unit, and injectors. If you can find a good used kit like I did you will be very happy with it!!
I love the turbo on my auto!! Its a fun car to drive! even though there isnt as much power as a 5-speed. Its still a really fun car to have turbo'd! Thats just my experence.
With it only being a stage 0 it is a nice kit that is low in price and the install is very simple can be done in about 6 hours if you take your time.
Also with a stage 0 if you are happy with it and looking for more power which I know you will like I did!!!! Yo can go ahead a buy the upgrades for the stage 1 and make a good low power stage 1 kit at around low 200 WHP that way your tranny is still going to be safe with you beating on it and driving it every day.
This is just my thoughts!
Hope this helps!
Chris
