There are a few shops around my town that are capable of doing custom turbo work...

My only concern is...I am trying to stay away from 1 big turbo, because the bigger it gets, normally the longer the lag lasts...So, I was thinking of getting 2 small turbos...that way, they kick in faster, and both still add up to the total PSI of a larger turbo...

I think this would work...

Any reason it wouldn't??

 

twin turbo setup would be the ultimate. But stay with the smallest turbos that way you get the ultimate spool like a t28 turbo. Maybe a t28 and a t3/t4 turbo. Go to www.cybernationmotorsports.com they make rsx turbos and i think they make custom turbos and they're located in florida.

 

It would be extremely hard to twin turbo a 4 cylinder motor and have it run good, and i'd say pointless.. it would be much more expensive and yeild no real benefit over a single (ie. look at why all supra's upgrade to single turbo's instead of bigger twins). A T3 style turbo would be all you'd need if you're doing a custom setup on your TC and you would be hauling A$$ with minimal lag. Do it!! i want to see some pics when you're done :D

 

yeah...a twin turbo for a 4 banger?....thatd be cool to see but still..smaller turbos spool faster and have more low end torque but thats VERY bad for the engine...just stick with a decent sized turbo and ull be fine...

 

all i have to say to that is lancer evolution... twin turbo baby and rockin a 4

 

The tC's 2AZ-FE engine is a nice setup but it is just not special enough. I believe Toyota could have done better in choosing the powerplant for the tC. They should have put a 3S-GE engine in it. In Japan, the 3S-GE is used in the Altezza and the older Celica. The 3S-GE is a 2.0 litre eingine that pumps out 200hp without any turbos or superchargers. It also comes in a turbo form that pumps out 255hp 3S-GTE, used in the Celica GT-Four. Notice the difference between the second to the last letter in the engine code. F and G. F is for fuel economy. G is for performance. I don't know why they don't bring over the good stuff overseas.

 

One properly sized turbo will always be superior to a twin turbo setup (in terms of boost), unless you have them running in series to compound boost. As this obviously does not have to be done with the tC, one turbo, properly sized, would be more than sufficient.

 

What evo had twin turbo? :?:

 

Turbo is a great weapon on the straights but in the corners it hinders with the car's handling. Sometimes the car can have too much power to do the job. Guys that want as much power as they can out of their cars are limited to the drag strip. People who want to have a lot of fun with their cars will focus on the balance between power, handling, weight distribution, and braking. People who talk about straight massive hp and torque do not look at what a car can really do on the touges (mountain passes). It's all about winding roads. Straight line racing is for people who have no skill.

 

Thats good. I think most just want the added power for that just incase I need to do 0-60 in 5.5sec or so. Also depending on how much more power you have compared to that N/A car, you will catch them. No road is a constant set of turns, you will run into a straight road some time.

 

...how you can have too much power. OK I can understand if you were talking about a hugh amount of power ... like 500 hp or a jet or somthing like that. We are talking about some additional power not a crazy amount. Yes mountian driving is fun ... and mountian racing is even more fun on a closed course ... but you still need enough power. You increase the power you should change the gearing ... yada yada yada. On the outherhand ... having more power is just better even for the street. The speed limit is 65 ... more power will get you to 65 faster...and funner.

 

mazda is makin a twin turbo AWD on a inline 4. releasing 06. hehe only if i can find the article...


with all that power you stil need to find a way to put it to the ground you know.

 

You need to tell that to the boys at Subaru and Mitsubishi. The Mitsubishi Lancer Evo and the Subaru WRX STi are two of the quickest cars around ... both turbo charged, both all-wheel drive, and both handle extremely well and can stop on a dime to boot.

If you want a "great weapon on the straights" go for a classic American muscle machine with a big V8. If you want a car that has the "balance between power, handling, weight distribution and braking", then go with an STi or Evo. If you want a car that is economical, has character, and is fun to drive, then go with a Scion.

By the way, fusionscion, the Lancer Evo does not have a twin turbo ... it has one LARGE turbo putting out 19 psi of boost into the 2.0 I4 and makes 279 HP!!

Subaru has a twin turbo 2.0L H4 model in its Japanese lineup ... the Legacy B4. One small turbo for quick response low in the RPM band, and a larger turbo to take over boost responsibilities at higher RPM. Quite the monster but I understand there is a noticible pause in power as the shift occurs between the turbo chargers. Just a little FYI.

 

I am glad someone said it...

Also, include turbocharged cars such as the 240, Silvia, Focus RS, and others that tear up numerous amounts of winding roads.

 

i think people are getting the wrong impression of the evo. its not twin turbo(two turbo's) its TWIN SCROLL TURBO(one turbo) and the turbo for the evo is pretty decent size for a factory unit. and i agree that a single turbo will be more efficient than two turbos on a I-4.

 

I wanna get a Turbo on my TC, Should I go for a Custom?! and how much?! or should I wait for a Kit?! Please Respond!! :?:

 

expect to pay 3 grand and up for a QUALITY kit =P tahts the general ball park to looks at for most turbo kits for a 4 banger if your really down to do it, hit up some local performance shops n see who wants to do a sponsorship. thatll drop the price A LOT if not FREE if they see it worth their while.

 

Back to the "too much power" subject... there is no such thing. If you know how to drive you can use all the power you can get, maybe not all the time but that's why we have a throttle pedal- to modulate the power. WRC cars are similar is size to an xA and they have near 500hp at sea level, they use it on dirt!!! Now, that's my definintion of FUN!!!

Obviously you guys have never heard of the AE86. It is a RWD hatchback that has about 130hp stock. Modified to about 160hp and a couple suspension parts, it will destroy your 250hp+ machines on the touge.

 

Hey ScionTCTrav, already messing with your TC huh!
