This thread addresses most commonly asked questions when someone is trying to decide if they should go with a turbo charger for their car. The information in here is based soley on the feedback of people who have already installed turbocharger systems on their Celicas, and on information provided by leading experts in turbocharging and tuning the 1ZZ and 2ZZ Celica engines. Its a long thread, but please take the time to read it fully, and follow any of the links that address the subjects you are interested in - you should find the answers you are looking for.

If you have a question that this thread does not address, please feel free to ask, and to suggest that we add it to the FAQ. Likewise if you know of some information that should be included in this thread and is not, please reply to the thread with that info and I will add it to this FAQ

1ZZ or 2ZZ powered MR2, Corolla, Matrix or Elise owners please feel free to contribute as well.

If you are wondering if Forced Induction is right for you I think this quote from Jlitman pretty much sums it up nicely:


jlitman said:
How deep are your pockets?

If very shallow, then no, do not boost.

If moderately deep, then go ahead, but keep in mind if problems arise, you will go broke fixing them.

If very deep, sure go for it. Why not.

If exceedingly deep, save yourself the trouble and buy a faster car.
Another funny and good post from Jlitman about project cars:

What Boost do People Run on stock internals safely?

FIRST - read this thread explaining the limits of boost on stock and modified internals: http://www.newcelica.org/forums/showthread.php?t=243977

Once you read that thread - here is some more information
1ZZ
Daily / normal use: 6-8 PSI is most common, some run as much as 11 peak
High Boost (racing): 10-11 PSI is most common, some run less
No Boost related failures have been reported
2ZZ
Daily / normal use: 6-7 PSI is most common, some run as much as 8.5 peak
High Boost (racing): 7-8 most common, some as high as 12
Some boost aggrivated failures have been reported, none directly cause by increased power / boost however.

What kind of gas Mileage do folks with Turbos get?
20-25 MPG on average is most common. Aggresive driving SERIOUSLY affects this number
Link to Gas mileage thread: http://www.newcelica.org/forums/showthread.php?t=199278


How will this affect the reliability of my car?
Running moderate boost on a GOOD professional tune is fairly safe. Running double digit boost and/or no tune is cruising for trouble. Many of the kits and installs tend to be problematical in and of themselves

What compression ratio is best for a turbo, and what gas should I run?
Lower is better, especially on pump gas and at high boost. Between 8:1 and 9.5:1 are ideal depending on your circumstances.
Link to thread with more info: http://www.newcelica.org/forums/showthread.php?t=326676

What should I change about the maintenance schedule for my car once I get the turbo?
My reccomendation is to cut all time and mileage reccomendations in half/ Also see Mike Lu's Turbo Maintenance Thread:
http://www.newcelica.org/forums/showthread.php?t=156497


How will this affect emissions / CARB eligibility?
Turbo kits are NOT carb legal on the 7th Gen Celica. They are probably emissions-illegal in most of the other 49 states as well. If you are lucky enough to live in a non-emissions area or one that does tailpipe only, we are all jealous of you!


Do I have to get my car tuned if I install a turbo system?
YES!!!! You need to have an Engine Management System of some sort, and you need to get it tuned as soon as possible after installaiton. The stock ECU will NOT be able to handle fuel managemant with different injectors and will NOT be able to fuel to teh correct air fuel ratios for a forced induction car.


What can I do to start learning about Tuning the car and what systems are available?
The Best system is the Power FC
Second best at this time is probably E-Manage
S-AFC does NOT work
Split second systems work but not as well as the Power FC or E-Manage
There is an Autronic SMT4 system in development
AEM makes a great Standalone EMS (Engine Management System) that has to be custom installed and tuned for the 7th Gen - no-one has done it yet
There are rumors that Hydra is working on a standalone for the Celica

At what point do I need to upgrade my fuel system? What changes should I make?
This is a MUST for folks going forced induction. Leaving it stock just isn't safe. You will need to upgrade your injectors and fuel pump at a minimum. For high boost applications (over 10 PSI) a return system is also a great idea. Smaay sells return systems with 1:1 pressure regulators. MWR also offers a system now.

Here is a link to some cool fuel systems:
http://www.newcelica.org/forums/showthread.php?t=276314



What are the best gauges to get?
This topic is VERY opinion based with regards to manufacturer so please just follow the thread below. For what its worth I feel that a wideband O2 with gauge and a boost gauge are the only essential ones.

What about Rear mounted turbo systems?
Rear mounted turbos do function but are not as efficient as front mounted - theres a ton of info in this thread:

What other changes should I make?
Colder plugs are a must. Denso and NGK are the 2 brands to go with.

Do I need to upgrade my clutch?
Yes you do.
Link to thread about what clutches people use and how well they work: http://www.newcelica.org/forums/showthread.php?t=199457


What octane gas should I run?
You should run the highest octane pump gas available, and race gas when racing (103/104 unleaded is good) Do not run leaded gas


Is there anything else I can do to protect my motor when boosting?
Yes there is - Water injection is a very inexpensive form of insurance against detonation. Check out Aquamist or Snow Performance for some nice kits.

I heard there is a difference in some of the newer GTS (2ZZ) cars that makes it more difficult to turbo - is this true?
Yes. The 2003 and newer 2ZZ powered GTS uses a drive by wire throttle system that makes it impossible to use the Power FC without a conversion to a cable throttle from 2000-2002. Most 2003 owners use E-Manage or Split Second. Additionally in 2004 Toyota added an Air Iinjection System to the exhaust manifold / head areas that means a flange for a 2000-2003 Turbo kit will NOT work on a 2004. The 2003 and newer GTS also uses a different connector configuration and pinout - the wiring for the 2000-2002 does not apply.

Is there an engine I can swap in thats better for boost than my engine?
If you have a 1ZZ yes, swap in a 2ZZ. Otherwise not really. Some people have done the 3S-GTE but its a royal pain, costs a fortune and doesn't net you much gain for the money. More info here:

How do I hook up the coolant lines to my water cooled turbo?
The water should feed in at the top and out at the bottom. The out line needs to get connected to the steel tube that wraps around the front and side of the motor and attaches at the back of the thermostat housing - that is the suction line. See link below for details.

**************
**************
Checklist for someone who is going to turbo their car

___ Get a compression check done - were all cylinders within 10 PSI of eachother? Were they above factory minimums?

___ Check the brakes - make sure they are in good shape (you will need them a LOT more after the turbo)

___ Check all tires - make sure they have good tread depth and pressure is correct

___ Switch to GOOD quality (Chevron) high octane fuel at LEAST one tank before turbo install. 93 octane is best but if 91 is all you can get in your area then use that

___ Clean the MAF

___ Purchse 6 quarts of oil, a new Toyota Oil filter and 3 quarts of transmission fluid - you will change al these components at the time of install

___ Purchase colder spark plugs to install with kit

___ Purchase a tube of black Toyota FIPG (silicone gasket maker)

___ Purchase about 6-10 cans of brake parts cleaner

___ Purchase a gasket scraper if you don't have one (razor blade stype works best)

___ Purchase tuning solution (power FC or E-Manage)

___ Purchase upgraded fuel injectors and pump

___ Purchase upgraded clutch and pressure plate

___ Purchase boost gauge (install before kit to make sure its working)

___ Purchase Wideband with Gauge (install before kit to make sure its working)

___ Purchase good boost controller. Install at same time as kit.

___ Purchase upgraded exhaust (the more free flowing the better)

___ Purchase complete Turbo kit or purchase everything reccomended in custom turbo kit link

___ Set aside money for tuning & dyno time - it will need to be done immediately after kit is installed

___ Put aside a minimum of a $500 reserve for incidentals.

___ Buy a reliable beater for use while your turbo car is down

I think however we should also realize that some of these kits are no longer available... Although they are out there, I think it would almost be false advertisment to say they are listed... You understand? Maybe Under SF and DA and ATR put somthing along the lines of 'No Longer Available New'

I mean yes, you could still get 'used kits' but both SF and DA and ATR are out of business.... I recently talked with David Draper and he is done selling his kits.... I think that some of these things should be noted so we don't have new comers coming in and being like 'Hey where can I get this SF kit... Sounds awesome... Than a month later - OMG I got ripped off!'

Thanks a ton for all the responses and information - please keep it coming!! I know it takes a while to respond to all the polls and surveys, but I think its going to be a great resource to have all this information centralized and summed up. Besides for helping out the noobs with the reality of a turbo it will help folks that are actually in the process of planning their system. Plus its just darn interesting for the rest of us too.

I will work on compiling all this stuff, updating links, and adding more stuff tonight (been swamped at work today - haven't been able to get to it)

Thanks again for all the help and input!

Hass uses the GT2871 for the 2zz. Much better fit than the RS. We left the stock fuel pump in mine without problems, but the injectors are 680's (IIRC) so it compensates. I just got the 255 pump and Jay thinks we can get a little more power out of her with the larger volume pump.

Sorry Boosted.
