Celica gt4 tuning

HI guys, i have a standard ST the only mod it has is a baileys dump valve. I want to start slowly and mod it up abit and make it into my little project. Hi mate, thank you for your responce, do you think i should save and get it all done at once or should i do it bit by bit as in start with the air filter and then get the decat and exhaust in a month or two? If the timing belt hasn't been done save your pennies, it's a big job and you'd be best getting the water pump and head gasket changed for a metal one with ARP studs, to keep the head pinned down tight.

There's a resonater box in the inner wing on the intake, remove this, it's a major restriction in the intake and is only there to reduce induction noise.

This is purely down to the turbo being able to spin faster than it has done before, so a re-condition is the best bet, buying a second hand turbo is a gamble as the same thing could happen again, if it's re-conned you know it's all good for turning the boost up. It's an expense but I'd also look into after market management, don't believe what you hear from back door tuning shops read ebay if you likethese ECU's cannot be chipped, if your going for a piggy back don't get a uni-chip.

The hks will give you a mush better sounding dump, you can get different attachments for fitting. Your mate is right, the engine is a non-interference engine but prevention is better than cure, it's a royal pita to get a tow to a garage and you'll need to wait till they get to it, plus if the belt goes it could damage other bits of the engine when it spins off.

The air filter you can do at any time, sooner the better. Just remember to remove the resonator box from the inner wing, this will give you a good little bit of extra power for free.

Toyota CELICA GT-FOUR с тюнингом НА МИЛЛИОН!

Have to agree, the gt-four is a great car, and it can be made an even better car with the correct mods. The resonator box you mention,any picture of this,or exact location,does it sit low down inside the wing?

It's in the inner wing, I'll get a picture of one tomorrow when I'm in work as I've just removed one for a customer. I would be looking at brakes and suspension before engine mods TBH. As a side note, look at how your insurance premium will increase I've circled the bits that pop off, the screw can be ripped off or you can remove the bumper to unscrew it.

It'll do no harm ripping it off as the box will be straight in the bin anyway. It won't be as prominent due to being enclosed but it will give the better performance gain. Have you removed the resonator box yet? Hi Thank you for your responce, no i have not remoeved anything yet just trying to work out what will be the best option for me. If you remove the resonator box first and see how that sounds then take it from there.

Will go look at your other thread now. Hi Gtforbes, should i remove the resonator box now? Ok mate will give it ago in the morning. Tried that hks ssqv again tonight I think there may be a problem with the valve and not how I fitted it as if I loosen the adjusting screw at the back and put my hand over the fronof it then it works as it should but when I move my hand it stalls Then if I tighten the screw the engine idles fine without me having to put my hand over the front of it but the it don't blow off like it should it doesn't do anything.

It's shouldn't do that should it? Sounds like its either broken or in need of a service. If your confident take it apart and clean it up, if not I wouldn't. You can post now and register later.

It had pop up headlights and a choice of engines from the underpowered 1. The turbo engine produced ps and came in a number of limited edition guises.

The later sixth generation had round headlights and subtle styling. ByToyota deemed the Celica to need an upgrade and the 7th generation model was introduced with distinctive triangular headlights.

Beware though as some countries had rev limits reduced from rpm to where full power is starting to come on strong. It seemed to be a bad move at the time reducing the power and hoping that strong sales would continue. Toyota have announced that the Celica will no longer be available in the USA due to declining sales.

The following modifications are usually performed by our Celica owning members, decide how far you want to go before you begin. Getting the right mods for your planned usage of the car is vital. Stage 3 competition mods just don't work well on the road. Stage 1 mods: Exhaust, Panel air filter, Remap, lighter flywheel. There is no shortage of parts around for the Celica particularly the 5th and 6th generation cars. Engine swaps are popular with owners looking to obtain the 2. Suspension upgrades will do a lot to improve the handling and ride quality.

After you have modded the car look at a full Remap using a new ecu such as that from Apexi in the guise of the power FC will unleash a few more hp. The Toyota ECU's are locked and very few are able to remap them so going the aftermarket route is the answer. Be sure to choose an aftermarket ECU with a knock sensor though. Get the breathing right with a sports manifold and induction kit with a cold air feed.

A boost controller will smooth the power delivery. Stick to boost levels of 15psi. A fast road cam and uprated turbo will take power up to around bhp. Traction is a problem on 2 wheel drive models so the four wheel drive limited editions are great project cars and can put some serious power down. The clutch can slip when large power gains are put through the transmission. If this is the case, or your clutch is getting old it will be time to replace it with a trible plate clutch in a high friction material.

A ligher flywheel will help the engine to feel more revvy and is quite handy for track use where the engine is mainly used in the high end of the RPM band. Fuelling upgrades should help to match the air intake charge and in some cases you will need uprated injectors, a bigger fuel pump and wideband Lambda.

Lowering the car by mm will help improve the handling and the cornering. Large wheels of 18 or 19 inches will be prone to tramlining and should be avoided if you are serious about performance.

What mods have you done to your Celica?Some Toyota Celicas may have many performance parts available sometimes dependent on the trim level. Out of the pool of available performance parts, we have narrowed down to the best parts available. The basic idea of performance parts is to optimize your Toyota Celica's chassis and engine to operate at its fullest potential.


In regards to engine performance, the parts you can get for your engine range from something basic like a cold air intake to a more complex system such as a turbo kit or super charger kit.

It is a little difficult to know exactly what to do first and if this affects that, what does this do, does this mod work, what's the best thing to spend my money on etc Please bear in mind that opinions vary and that as I see things these are the first 10 mods I would do to my car if I was to start again on a stock car.

The aim of these small 10 modifications are to be low cost, quick and "mostly easy", to provide a small foundation on which to build and to release a bit more power from the engine.

They will also guide you around the car looking at engine bay, suspension and other bits and pieces. These mods tend to focus on the key weak areas, as well as being the cheaper ones!

One of the golden rules for modification is intake, exhaust, fuel and ignition. Something that is always worth bearing in mind. Demon Tweeks and Fensport sell insulating material and tapes, see the links section for more shops.

Modify the IC pump so that it runs continuously on the s and s - I wouldn't bother on the as the control system appears to be better. For all ICs - wash out the IC with petrol to clean the interior to ensure it transfers heat efficiently.

Maybe worth a few bhp, and should help to keep your engine safer To increase power the boost needs to be turned up. To do this cheaply fit an RV or alternatively called a Dawes Device. On your stock setup you need to watch what boost you run, or you will hit fuel cut, a safety feature to help prevent damage. Guide levels for fuel cut are:. On the shopping list really should be a bigger turbo and some way of controlling all this lot i. How much is the car worth? How much do you plan on spending on mods?

Would you be better off putting that modding money towards a faster car?!? Bear in mind that the already comes with bhp, better intercooler, different cams, larger injectors, metal head gasket, better pistons, different turbo, better fuel maps, much better engine management, bigger throttle body, revised intake manifold, revised oil filter location, better gearbox, better rear diff, mild head porting, massive brakes, much better suspension and is not so prone to rust!

The Toyota Celica GT4 looks like a bargain, as to me it seems that you get quite a lot of car for your money, but is it worth me buying. They seem to have plenty of tuning potential, but what should i be looking out for when i go to buy, and what are the most common problems with them? Mastodon2 13, posts months. Can't speak with regards to buying advice, but I will chip in to say from what I've read they are supposed to be great cars. You won't get Elise-style handling or feedback, and the engine is not as powerful as it's rallying contemporaries the Lancer Evolution or the Impreza, but the tuning potential is there if that's your thing.

On the plus side, having less powr means you will be able to drive it harder when you are having a bit of a hoon and you won't catapult yourself into licence losing territory so quickly! They also look and sound fantastic. I was out for a drive with my brother not an hour ago and passed a white GT4 sitting at the side of the road. Buy one I say, love it and then lament the complete and utter mess Toyota made of the Celica in later years! Riknos 4, posts months. RobCrezz 7, posts months.

Great cars after some minor mods. Mr E 19, posts months. That's a pretty bold statement! Depends on which Impreza you are comparing them too? The most powerful production Celica GT4 ST was the Japanese market model, at bhp or so, and the export model was bhp or there abouts.

More powerful than naturally aspirated Imprezas and some of the lower powered turbo models, but a iirc most WRXs and certainly STis were "bhp" out of the factory but actually considerably more powerful.

However, the Celica is not an underpowered or slow car by any means, and as said, the tuning potential is there to make it even more powerful.Here we describe some common upgrades for your CT26 Turbo.

There are a list of companies that do repairs, rebuilds, and upgrades. See the Turbo Rebuild Pageif you dare. STAGE 0? This is mostly for ST and ST owners. What you do is get a CT26 from a Supra Turbo, Preferably as new as possible.

These can be sourced for as little as dollars, and a basic rebuild is cheap. If you have the money of course you should go for the bigger upgrade, but if you are on a budget this is perfect.

Visit the FAQ for more information about the actual installation procedures. There are no horsepower numbers, but it basically makes your car more aggressive on the upper end without any negative fallbacks. If u are familiar with DSM then this would be like moving from a stock turbo to a 16g.

In terms of horsepower, say the stock turbo was good for horsepower, then the supra would be good for hp on our cars based on percentages, it's not that much bigger, but it will carry you further. If you are putting it on an ST you can bump that figure a little higher due to the response of the Twin Entry System. That would put you close to or above the power of the ST turbocharger.

This is the most common of upgrades that are offered by some of the companies below. The compressor is removed and replaced with a TO4 "B" compressor wheel. These are usually from Garrett or similar larger turbos.

The B series is not the largest of the TO4 series, but significantly larger than the stock or supra turbo compressor. The compressor housing is bored out to match the size of the new compressor wheel. The exhaust side is left alone. This formula leads to a turbo that has very little lag if at all.

Speaking in trim, that actual size of the compressor wheel, this would be a 46 or 50 trim. An example picture is below.

This is the more aggresive of turbo upgrades. This is fitting a very large compressor wheel into the compressor housing. Usually this also involves modifying the exhaust wheel by clipping.

celica gt4 tuning

Clipping the exhaust wheel is removing some of the material at an angle which will allow more exhaust to bypass the turbine in extreme conditions. The reason this is done is that when u are using your big upgraded turbo at a high psi and RPM, the exhaust cannot get out fast enough.

So the clipping procedure will allow a little more flow at the expense of lag. The large compressor wheel also has it's share of lag, which most don't mind for the absolute kick in the pants it offers once spooled up.

If you do go with this upgrade it is suggested that you upgraded your downpipe and exhaust system to help the turbo spool up earlier. This upgrade usually contains a TO4 "E" upgrade wheel. Speaking in trim this would 54 and Some companies even offer a wheel which is even larger. Most consider this overkill and would never operate at full potential.It was created to compete in the World Rally Championshipwhose regulations dictate that a manufacturer must build road-going versions of the vehicle in sufficient numbers.

These vehicles are referred to as "homologation special vehicles". The ST is Toyota's most successful rally car. It also won the European Rally Championship. Since then other Japanese manufacturers have been successful in the WRC. The convertible never went into production, but the concept went to the liftback model which began production in October Inside, the original GT-Four has a differential lock switch near the hand brake for the and model years. As with other front-drive Celicas, the ST received a new grille, tail lights, and alloys.

The export version also has ground effects, noticeably the side spoilers and dual front round fog lights. The center differential was changed from a manually lockable unit either open or locked to a viscous-coupling limited-slip type. One car was sold at each of the 77 Toyota dealerships in California.

They were sold in as models, and do have the viscous-coupling center differential. The first 21 units of the Celica ST were built in December as prototypes for various tests. The production model was launched in Japan in Septemberand delivery began a month later.

The Full-time 4WD system in the GT-Four has viscous coupling center limited slip differential and some models are equipped with a Torsen rear differential. All export market GT-Four are wide-body Liftback models with flared fenders.

European and Australian specs come with EF with 3. With its sport-style interior, power-operated driver's seat, auto tilt-away steering wheel, SRS Airbag, and cruise control as standard equipment, the ST All-Trac Turbo was the most expensive Celica yet. With a 2. The European versions have standard ABS. Headlight washers and heated door mirrors are also offered.

Sunroof came standard in the UK models, or optional for cars in the Continent. However, System 10 Premium Sound System and Leather interior were only available as options in selected European countries, and were not offered in the UK. The Australian spec was less luxurious than other destination models. Cruise control, leather, and sunroof were not offered. Early models didn't have ABS and fog lights which became standard few months after introduction.

However, Australia was the country with the large numbers of ST This facelift included the new Toyota ellipse emblems on the hood and trunk, restyled tail lights with smoked red frame, and shorter gear shift.

The Japanese models also got round-shape front fog lights. The All-Trac Turbo retained the automatic air conditioner, but the fan switch was changed from the push button type to the more conventional rotary type.

Special features include:. Out of units, were for Japanese market, were allocated to Europe, were delivered to Australia, 25 for Singapore, and very few made a trip to New Zealand and general markets. The units homologation cars built to allow Toyota to enter the GT-Four as a Group A car in the World Rally Championship also featured extras such as all of the plumbing required to activate an anti-lag system, a water spray bar and pump for the front intercooler, a basic water injection system, a small hood-mounted spoiler aft of the windscreen washers also standard fit on all UK cars and an extender rear spoiler mounted on risers.

The Japanese market ST came with a standard automatic climate control air conditioner, but ABS was initially optional and became standard from August
