Newbie Questions

Engine

Q: What is the difference between VVT-I and VVTL-I?

A: Well VVT-i is Variable Valve Timing - with intelligence and VVTL-i is Variable Valve Timing & Lift with intelligence.

VVT-i is a tuners best friend as it tunes your car as you drive. Always adjusting your valve timing but the way of spring loaded cam gears that can change in a heartbeat at the computers wishes. The new VVT-I motors also have a computer controlled ignition system that changes ignition timing in a moments notice along with the variable valve timing. So when your cruising along on the highway or downtown and your not looking to rip up the asphalt the computer senses that, adjusts the valves and ignition to make the motor use less fuel.

Now if you got that digested and feel confident about your VVT-i knowledge then we are going to give you a shot of "roids" in your arm to let you feel how the VVTL-i feels when you hammer on this engine. The VVTL-i engine in the new Celica GT-S is ready to throw you back in your seat and take you for a serious ride. The VVTL-i motors use all the same technology that was mentioned about the VVT-i motors but adds a twist to the deal. It not only changing valve and ignition timing on the fly, it also has a second set of cam profiles on each cam to give you the "race car when you want" it approach. Tach it up to 6 grand and the motor turns into a monster. The motor puts out a scream as it warps into hyper drive! It feels like a race turbo kicking in with all the added horsepower and torque in a matter of a few hundred rpms.

Q: What is a proper way to break in a new car or a car with a brand new engine?

A:  Generally you want to break in the car for the first 1000 miles. Try not to over rev the engine much above 4k rpm and try to not to keep a constant speed for very long and do not use cruise control.

Q: When should I get my first Oil Change?

A: There is much debate on when you need you first oil change, Toyota says 7500 miles, some say right after break in at 1000 miles. But a good general rule of thumb is around 3000 to 3500 miles.

Q: When should I switch to synthetic oil?

A: Well, you don't have to but people recommend that you do it around you second or third oil change

Q: What kind of gas should I use for my GT/GTS?

A: For the GT the owner's manual recommends 87 octane regular unleaded fuel. The Celica GT is not designed to take advantage of higher octane gas, so while putting it in will not harm your vehicle, you will receive no benefit and the cost is significantly higher. If you are hearing a "knock" or "rattle" sound from your engine during high load, and the problem is reduced or eliminated by higher octane gas, then you probably need an engine tune-up.

For the GTS the owner's manual recommends 93 octane gas due to the higher compression ratio/higher performance engine in the GTS.

For more information on octane ratings see "What does Octane mean?"

Q: What is a MAF/MAS sensor?

A: MAF/MAS sensor is "Mass Airflow" sensor. It measures the numbers of molecules of air going into the intake manifold at any given moment. The sensor then sends these measurements to the car's ECU and ECU supplies adequate amount of fuel for the air coming in.

 

Suspension

Q: Does the Celica GT have the same suspension as the GTS?

A: Yes. The GT and GTS suspension are the same except that the GTS comes with P205/50R16 tires on 16" 5-spoke aluminum alloy wheels.

Q: Can you put the GTS wheels on a GT?

A: Yes.

Q: What are springs and what do they do?

A: Springs are mounted on the strut and lower the car between 1 and 2.5 inches. However springs have a set drop rating and cannot be adjusted to various heights..

Q: What are coilovers?

A: Coilovers are an adjustable spring (or coil) mounted over the dampener. Using a threaded collar - you can adjust the springs up or down on the strut. Raising or lowering the car, and changing the dampening effect.

Q: What is camber?

A: Camber is the angle of the wheels from top to bottom. The more negative camber - the more the top of the wheel is pointed towards the car. A degree or two of negative camber is good for hard turns as the outside wheel is angled to take the force of the corner and keep the car planted in the turn.

Q: What is toe?

A: Toe is the left right angle of the wheels. Sometimes the rear wheels of other cars are placed "toe in" to make the car more stable at high speeds. Where the left wheel is turned right a degree, and the right wheel is turned left a degree.

Q: What are camber plates?

A: Camber plates sit at the top of the strut, and allow the strut to be adjusted in several directions. Changing the attitude of the wheels. You will also see the term pillowball mounts used when discussing camber plates.

Q: What is understeer?

A: Understeer is when the car plows into a corner. The wheels are turned, yet the car is still going straight.

Q: What is oversteer?

A: Oversteer is when the rear of the car swings outward towards the corner. This is also known as "tail out" and "fish tailing".

 

Interior/Stereo

Q: How do I remove my shift knob?

A: Just twist to the left or counterclockwise. It will just unscrew.

Q:Where are my 7th and 8th speakers?

A: Sometimes you need to install new sound equipment. To answer this question, there are tweeters up in the top of the door (2 speakers), there are mids in the doors (2 speakers), and there are mid-tweets in front of the mids on a platform (2 speakers), and finally, there are mids in the rear (2 speakers). 2+2+2+2=8. As for right now, my system has 8, but I now have MB Quart front components, the stock rears, and JL Audio subs in back. Thats a better way to say that you have 8 speakers.

Q: How can I add a subwoofer to the stock stereo in the Celica?

A: To do this you will need an amplifier and your subwoofer and a wiring kit for the amp. There are two ways to hook this up. Here are the steps common to both:

1. Run a fused power wire from the positive terminal on the battery to wherever you plan to mount your sub.
2. Run a remote wire from any switched 12-volt source in the car (e.g. the ACC wire that runs to the stock deck) to where you want to mount your amp.
3. Run a ground wire from your amp to a good ground.
4. Get audio input to your amp **

** Step 4 is the part that can be done two different ways:

1. If your amplifier accepts speaker-level inputs, just tap into the rear speaker wires and run speaker wire directly to the speaker-level inputs on the amp.
2. If your amplifier only accepts RCA inputs then you need to get a speaker-level to RCA converter (which you should be able to get from any stereo shop or electronics store). As above, tap into the rear speaker wires and run speaker wire to the converter. Then run an RCA cable from the converter to your amp.

Note that in order to get to the rear speaker wires you will need to remove the rear interior of the Celica.

Brakes

Q: What are the dirrerences between the GT and GTS brakes?

A: GT has Power-assisted with 10.0" ventilated front disc/rear drum . GTS has Power-assisted with 10.8" ventilated front disc/10.6" solid rear disc

Q: Can I replace GT drum brakes with GTS stock rear discs?

A: In theory yes, but no one has tried it and probably would cost more than it is worth.

Q: How do I paint my calipers?

A: You need to buy either high temp engine paint (1500 degree) or laquer paint like Folia Tec

Q: What is break fade?

A: Brake fade occures when the break rotor and the break pad overheat and you loose your breaks.

Q: What is rotor warping?

A: When the rotors cool down very fast from a very high temperatures, the rotors loose their original shape and warp. It is due to the same reason why a very hot glass will shatter if you pour cold water on it.

Q: What do stainless steel break lines do and are they worth getting?

A: Stainless steel lines simply do not expand like the stock rubber hoses under extreme pressure when you press your break pedal. When the rubber hose expands, you waste some of the pressure in your breaking system and therefore loose some break system performance..

Q: What are vented brake rotors?

A: Vented brake disks are hollow on the inside. They look like a sandwich and allow air go inside of them, therefore cooling them off. Remember, the cooler your brakes are, the better braking performance you get.

Q: What are slotted rotors?

A: Slotted rotors have slots on their surface. These slots provide additional surface area which help dissipate heat better and also clean  the pads. The rotors can cast slotted or slotted after they were made. Cast slotted rotors tend to last longer and be more cracking and warping resistant.

Q: What are cross drilled rotors?

A: Cross drilled rotors have numerous holes drilled in them in a variety of different patterns. These holes help the rotors to cool better and weight less. Just like the slotted rotors, they can be cast drilled or drilled afterwards. In general, cross drilled rotors tend to warp and crack fast that plain or slotted brake rotors.

Q: What is the difference between different types of brake pads?

A: It all comes down to what the pads are made of and the temperature at which they perform the best. Street pads are made of a softer material and they work well at lower temperatures and do not require any warm up time. They are perfect for eveyday driving. For weekend racers, semi-race pads are their choice. They are made of harder material and perform well at offer both low and temperatures. And finally, the racing pads offer the best high temperature performance but they do require to be warmed up before working well. Remember, that street pads will cause brake sooner than the semi-racing and racing pads.

Q: What is brake bleeding and how do I do that?

A: To bleed the brakes means to flush your brake system fluid with new brake fluid. Sometimes, brakes need to be bled if you suspect that you have air in your braking system. To learn how to bleed the brakes, please follow this link.

Q: What is the difference between the horsepower at the flywheel and at the wheels?

A: At the flywheel horsepower is always higher than the wheel horsepower. When the power is being transferred from the engine to the wheels, so of the power gets wasted in the drivetrain moving parts, such as the transmission and differentials. So, the wheel horsepower is the power that actually made it to the wheels. AT transmissions loose more horsepower than the manual transmissions due to the increased number of moving parts.

 

Lighting

Q: What type of bulb does Celica have in the High Beam headlights?

A: 9005.

Q: What type of bulb does Celica have in the Low Beam headlights?

A: H7 Halogen.

Q: What type of bulb does Celicahave in the foglights?

A: H3 Halogen.

Q: Where can I find out about other various bulbs?

A: The bulb list can be found at http://www.newcelica.org/other/faq/bulbs/index.htm

 

Modifications

Q: Will aftermarket parts void my warranty??

A: The only time a mod will void your warranty is it is proved that that aftermarket part is the cause of failure of a part covered under your vehicle warranty. TRD parts, if installed by a toyota dealership, will not void your warranty, infact, they will be included in the remainder of your factory warranty. Anytime you start modifiying your vehicle, though, be prepared for some headaches when it comes to warranty work. just a head's up.

Q: What is the Butterfly Valve modification?

A: The "butterfly” is a plastic part located inside the air box that is recognizable by the small white flap in the middle. This is a very minor modification which has not shown any significant power gains but results in a deeper sound when accelerating it was placed there by Toyota to help MPG by reducing the amount of air that enters the engine & to keep the car a little quieter at RPMs below 3500.

Positives: Deeper Sound, Little Bit Better Acceleration
Negatives: Possible Harder To Start Car

Q: What is the S2000 antenna?

A: The S2000 antenna is a short black rubber stock antenna on the Honda S2000. You can use this to replace the original tall metal antenna the Celica comes with. You will have the same reception as the stock antenna. This is a cosmetic modification only. Part #39151-S2H-EO1. Order from any Honda parts dealer.

To install: Unscrew stock antenna, use wrench if nessesary, but should come off by hand. Screw on S2000 antenna tightly. This may require some pressure since the threaded stem of the S2000 antenna is shorter than the stem on the stock antenna.

Q: I got a GT and I want the GTS pedals, where can I get them?

A: For you GT owners who want the pedals that the GTS gets standard, you can get them through many places. Either your local Toyota dealer or one of the site sponsors. The Part Numbers are: 31321-53010 Clutch and brake (manual) (around $5 each) 47121-53010 Brake pedal (auto) 78120-20790 Accelerator pedal (around $50 for the assembly) 58192-20090 Footrest (around $65) Prices vary through whom you order from, but typically you can expect to pay between $100 and $160 for the whole set.

Q: What's the difference between a TRD Extended and a TRD Standard Exhaust?

A: The TRD exteneded exhaust was designed to be used with an aftermarket rear valence. So if you intend on having GFX you may want to consider purchasing the TRD extended exhaust. If you would like to see pics of the extended exhaust on the stock rear valence you can below.

TRD Extended and TRD Extended2

Q: What is the difference between a "Cold Air Intake" and a "Short Ram" Intake?

A: A Cold Air intake or CAI is

Q: Do I need to get an S-AFC if I put an intake on my Celica?

A: Not necessarily. You might want to but it will require expensive dyno tuning to get the settings right. Not every car is the same, so someone elses settings probably won't work for you.

Q: I want to get new rims/wheels, what is the bolt pattern and offset for the Celica?

A: The bolt pattern is 5 x 100 and 39mm offset.

Q: What are Clear Corners?

A: For install instructions, see "How to Install Clear Corners"

Q: Why are Celica aftermarket parts very few and far between than other car's aftermarket parts?

A: Because 7th Gen Celicas are still new and it takes awhile for R&D.

Q: Ok, I want to get some mods, where do I purchase them from?

A: You can start by looking in the sponsors section, most mods can be found through them.

Racing

Q: What is Auto-X?

A: Auto-X or Autocross or "Solo2" is an event where you race around cones on pavement trying to beat the clock. It is a safe event where speeds only reach around 50+/- MPH, and only 1 car is on the course at the same time. You are required to have a car in good working order, and a helmet. No other "special gear" is required to run in an autocross.

Q: What is Rally-X?

A: Rally-X or Rallycross is pretty much the same as autocross - only on dirt. You have to navigate the course of cones in the rough. Rallycross is generally a little harder on your car because of the rocks and bumps, but it adds a bit more spice then flat pavement.

Q: What is the SCCA?

Sports Car Club of America. They hold local and national events all over the country. Organizing autocross, rally events, etc. http://www.scca.org
