I want to turbo my Gt celica but can’t find a turbo. Someone suggested I get a manifold from a “gts” but idk what to do or what that is… so maybe he’ll me with some ideas because I want to build this car to be performance ready. It’s my drift car.

My choice is naturally aspirated, Look at all the TRD used Japanese motor dealers & find a front clip 2.5-5k it’s just a straight up swap - rebuild motor if you like but get it running & slap in the 3sge RedTop beams - all wiring & computer is important - will likely come with the heavier axles, but replace anyway they are cheap

Dude I need a step by step I have no clue what that is and I’m new to imports.

Only you know if you are capable to tackle the job, YouTube is your best friend, get a set of shop manuals on eBay for the car it’s coming out of (these are mine) (might be handy to have both) there are a few decent videos on the swap - watch them all more than once and while you do the swap watching on a big screen tv in the garage 🤩 - Job requires basic auto mechanic skills, basic mechanic tools, I like a journal to write your steps as you follow the video, write notes, tools/sizes used and about that procedure, corresponding number ziplock bags as you go logging all hardware removed which enables putting everything back together much smoother with confidence - a cleanish dry place to work, and patience good luck buddy- take a lot of pictures, video point out how things look - may want to review

It's a big job. And if you put a turbo on your present 5S-FE engine, you will need something other than your existing ECU for your fuel management. I've seen people piggy-back fuel management add-ons to their existing ECU's with some success. You really have to have experience and know what you are doing to have a chance of making that work.

Given you like 6th Gen Celica's, and they are now getting past 25 years old (which is the threshold that you can import and drive a foreign-market vehicle in the US), why don't you import a Celica GT-4 that already has the turbo 3S-GTE engine in it, along with 4-wheel drive?

Your next step should be maintaining the vehicle. It's a almost 30 year old car. Suspension, brakes, bushings, whatever. Don't even think about turbos or engine swaps until the vehicle is ready.

Where would I find this and isn’t it super expensive?

Super expensive means different amounts to different folks. How much will you spend (including the car you already bought and the cost to get everything you need to make it a turbo, and the cost to do the installation and troubleshooting to make it run properly?

I see one ST205 here in the US with an asking price of $31,995.00, and another for an asking price of $26,910.00. There are 2 others for sale with a note to ask the seller for the price. That is through one agency. I don't think the asking price equals the selling price. A 1994 Celica ST205 sold on BaT back in 2019 for $16,150.00. There are several available in the United Kingdom from $16,000.00 - $20,000.00, but you would have to include overseas shipping on those. Not cheap. But I would imaging the total cost of your own car along with all that is needed to put a turbo in it and make it operate well won't be much less. I'm hoping others might chime in with opinions as well.

What year Celica GTS did you find a manifold from? I don't believe that a 1995 North American Celica came in a GTS model - just GT (ST204) and ST (AT200). Your engine is a 2.2L 5S-FE. What engine were you able to get a manifold from?

First, L4 is a generic description for an inline 4-cylinder engine, just like V8 is a generic term for a V-shaped 8-cylinder. engine. Your engine model is a 5S-FE, 2.2L. I have the exact same engine in my 1993 Celica GT convertible.

The 2002 Celica GT-S that has the intake manifold for sale is from a 2ZZ-GE engine (if it is from a USDM Celica). That engine was not a turbo engine. And I really doubt an intake manifold made for a 2ZZ-GE engine would fit onto a 5S-FE head - they are very different engines.

Save yourself from a miserable project and do a swap - drops right in

Gen6 Celica GT Feasible Engine Swaps

1. 3S-GTE - This is one of the best engines ever made, and guess what? It drops right in to your Celica, assuming you have a ST202, ST203, or ST204(Which is the USDM GT.) The greatest quality about this engine is its power. From the factory, this 2.0 liter, turbocharged engine produces anywhere from 190(USDM ST165 fourth generation Celica) to 254 horsepower(JDM ST246 Toyota Caldina), depending on the generation of the engine. Because of the tuborcharger, this engine has great low-end torque as well, and has a huge power potential. In nearly every Supra that has been built by a tuning company for racing purposes, the powerful 2JZ-GTE engine has been scrapped in favor of a 3S-GTE, due to it's lightness, huge power potential, and it's durability. If you're going to do a swap and you're able to(And willing to do a little more work than other swaps if you've got a ST), this is the engine to swap in to your Celica. Period. This engine will bolt up to any Celica that has a S-series manual transaxle.



Horsepower

3S-GTE engines:

1st Generation - 190 HP(USDM '87-'89 Celica All-Trac), 187 HP(JDM '87-'89 Celica GT-Four)

2nd Generation - 200 HP(USDM '90-'93 Celica All-Trac, USDM '91-'95 MR2 Turbo), 221 HP(JDM '90-'93 Celica GT-Four, JDM '89-'94 MR2 Turbo), 231 HP(JDM '90-'93 Celica GT-Four RC)

3rd Generation - 239 HP(Non-JDM '94-'99 Celica GT-Four), 241 HP(JDM '95-'99 MR2 Turbo), 251 HP(JDM '94-'98 Celica GT-Four)

4th Generation - 254 HP(JDM ST246 Toyota Caldina GT-Four)



2. 3S-GE - This engine is another engine that comes standard in many Celicas, including the sixth generation Celica ST202 and ST203(Which, sadly, aren't available in the US.) It's the same 2.0 liter block as the 3S-GTE, but rather than being turbocharged, this engine is naturally aspirated, resulting in less power and less torque. This engine is an option for people who have a Celica and want to do a swap, but they don't want or are not allowed to have a turbocharged car. Even without the turbocharger, this engine is still powerful though. It puts out 177 horsepower and 142 lbs. ft. of torque in the earlier models, and the later models have BEAMS VVT-i (Identified by red valve covers and intake manifolds), resulting in 197 horsepower and 152 lb. ft. of torque. Some people may think that they can swap this engine into their car and later turbocharge it, but this is not a great idea. The internal components on this engine and the 3S-GTE are drastically different, so to make this engine turbo-ready, it would require the use of internal engine parts to strengthen the engine. If you want a turbocharged engine, it'd be much, much easier and cost-effective to simply drop in a 3S-GTE in the first place. This engine will bolt up to any transmission that comes on a ST202, ST203, ST204, or ST205 with no problems, though the stock tranny may not be up to the task of handling high horsepower levels if you have a USDM GT(ST204) for example.



3. 4A-GZE - This supercharged, 1.6 liter engine, is used in some first generation Toyota MR2s(Chassis code AW11), and is also used in the AE92('88-'91) and AE101('92-'95) JDM Toyota Corollas. In the oldest versions of the AE92('88 and '89), and the AW11, this engine only produces 145 horsepower. However, in the later versions of the AE92('90 and '91), this engine produces 162 horsepower, and in the AE101 form, this engine produces 167 horsepower. This engine has excellent low end torque, and is generally recommended over the 20 valve 4A-GE for street driving because of this. This engine will swap directly into any Celica with a 7A-FE(USDM ST) because both engines are A-series engines. This engine will bolt right up to your stock USDM ST(AT200) transmission, though the stock tranny may not be able to handle the 4A-GZE's boost very well. It's advised that you simply use the tranny that comes with the 4A-GZE engine.



4. 4A-GE(20 valve) - This 20 valve(Five valves per cylinder), 1.6 liter engine is naturally-aspirated, and is found in some JDM Toyota Corollas. It comes in two versions, the first of which is the "Silver Top" version and is found in the AE101 Toyota Corolla, produced from 1992 to 1995. This version is much easier to find, and is identified by a silver valve cover. It is an older engine than the silver top, and is rated to have five less horsepower. Unfortunately, this version of the engine is over-rated, and it's estimated that this engine produces about 10-20 horsepower less than advertised by Toyota. The "Black Top" version of this engine, however, is not over-rated, and it produces right around 165 horsepower at the crank. This version of the engine is identified by a black valve cover, and this version can be found in the AE111 Toyota Corolla. Both engines have advanced and unique features, such as five valves per cylinder(Compared to the traditional four), and four individual throttle bodies(One per cylinder). With only 117 rated lb. ft. of torque, both engines lack the low end torque that the turbocharged and supercharged engines have, and these engines produce most of their power up high in the powerband through the use of variable valve timing(VVT) and the G-series head. Because of this, the 4A-GE is generally used more for race applications due to it's narrow powerband, and the 4A-GZE is generally recommended for street driving, due to its torque that is spread out throughout the entire powerband. This engine will swap directly into any Celica with a 7A-FE(USDM ST) because both engines are A-series engines. This engine will bolt right up to your stock USDM ST(AT200) transmission.



Other Solutions

If you don't wish to swap an engine into your car or are unable to(due to lack of a garage, mean parents, etc.), there are other solutions for you that can help your car go faster.



1. Turboing the 7A-FE or 5S-FE - A few people have turbocharged the 7A-FE(stock engine in the USDM ST) and the 5S-FE(stock engine in the USDM GT), and most have had good results. Burien Toyota made a kit for the 5S-FE that allows you to run up to 7 psi of boost reliably, and JGS Tools offered many of the parts needed to turbo your 7A-FE and allow you to run around 7 psi of boost, with more information and links to where to get the necessary remaining parts.



2. Turning the 7A-FE into a 7A-GE - The idea of taking the head off of a 4A-GE engine and bolting it to the block of a 7A-FE engine to get more power has been discussed many times, and the conclusion is that it's quite a bit of work to build a hybrid 7A-GE, but it can be done. It involves taking the head off of an older 4A-GE(The blue or red top will be much easier than the 20 valve black top or silver top.) and bolting it to the 7A-FE block, configuring the timing belt(The 4A-GE or 7A-FE belts don't work.), changing or modifying the ecu and wiring(Because the 7A-FE's rev limiter limits power up high and may not work optimally with the 4A-GE intake manifold and injectors), and a few more things. Also, this conversion will not yield a whole lot more torque than the stock 7A-FE. Torque figures will be about the same as stock, though horsepower will increase a bit because of the G series head and higher redline. Club 4AG has lots of information about building a 7A-GE and has comments from people who have done this.
