Hi, maybe you have heard about the 3sgte gen 4th, an engine from the Toyota Caldina ST215. This swap has been done on some celicas since last 3 or 4 years. I buy this engine too but I discover after that there is not a lot of information about this engine. So I decided to make a big file that include pics of the engine, some differences between this engine and other generation of 3sgte.
First of all, the 3sgte gen 4th come off a Toyota Caldina GT-T ST215 make in 1997 to 2002 in Japan. This car can has automatic or manual tranny (very rare). Here’s a pic of this car.
This engine is similar to other generations of 3sgte. Here are the main differences :
-the turbo is a CT20b (as on ST205 3sgte)
-the turbo and the exhaust manifold are casted togheter (its impossible to remove only the turbo)
-this exhaust manifold will not fit any other 3sgte head because it doesnt use the same bolts pattern (7 bolts)
-the turbo exhaust housing does’nt use the same bolt pattern (so the downpipe is different)
-the intercooler is air to air
-the injectors are 540cc/min
-the ignition is different : no distributor. There is one coil/spark plug. This system is more known as COP ignition (coil-on-plug). The ECU control the ignition timing using two Variable Relocutor sensors. One is triggering a toothed wheel at the crankshaft pulley, the other is triggering a little arm at the end of the intake camshaft.
-The intake manifold is side-feed manifold.
-The oil pump is different because it has to locate one VR sensor.
-The head is slightly different because the exhaust ports are bigger (look at the drawing)
-There’s no EGR or TVIS system because its a JDM engine. (more pollution but… does’nt matter
Here’s the specs of the ST215 engine and the one of the ST165, ST185 and ST205 :
YEAR COMP DISPL. POWER TORQUE CAR
1986-1989 8.5:1 1998cc 182hp@6000rpm 185lb-ft@3600rpm ST165
1990-1993 8.8:1 1998cc 220hp@6000rpm 225lb-ft@3200rpm ST185
1994-1999 8.5:1 1998cc 241hp@6000rpm 225lb-ft@3400rpm ST205
1997-2002 9.0:1 1998cc 255hp@6200rpm 240lb-ft@4400rpm ST215
1-Does it will fit my tranny?
Answer : This is an « S » engine so, any tranny that come off this engine family will bolt-on as 5sfe, 3sgte, 3sge, 1mzfe and 3mzfe too.
2- Does it use the same engine mounts?
Answer : Yes, it does because its again an « S » engine.
3- Can I fit an other 3sgte ECU to run it?
Answer : No because the stock ECU is needed to control the ignition.
4- Does this swap has been done?
Answer : Yes, it has been done. There are maybe 10 of them. There’s one in Russia, Toysport have done one, Dr Tweak has done one in a 6th gen Celica, two or three more on ST185s in USA. There’s one done here in Quebec but I have never seen him. And I’m currently doing mine.
5- Does this swap cost a lot more than other 3sgte?
Answer : I’ll say a little more but you will have a better block, a newer engine, the ignition is better, you will get a CT20b turbo (really better than CT26), you will get more stock boost (14psi stock).
6- Does the parts are hard to find in America?
Answer : A little more, but now, with internet, you can found everything you want. That’s how I replace my broken PCV valve, I met a guy from UK on the net and I told him if he was able to get me the PCV valve, he said yes and he send me the part after receiving the money.
TIP : If you want to swap a ST215 in your car, be sure to get a front clip or be sure to have the whole wire harness and the right ECU. You will need to add maybe 2-3 feet of wire for the wire harness because the engine came off a right hand drive car. If you can, get the manual ECU, it will be easier to swap.
Here’s some pics of the engine and other components :

For them who wants to know what my swap will seem, I’m swapping a 1999 3sgte gen 4th into my 1991 ST184. I will use a Megasquirt Standalone ECU and a custom wire harness to replace the missing ECU and the cut stock wire harness. I will replace the stock CT20b turbo with a t3/t4. I will replace the exhaust manifold with a equal leght tubular stainless steel one that I will customize to fit my 4th gen head. I will use a custom stainless steel 3 inches downpipe. I will build a 3inch exhaust all way long with a N-1 style muffler with a 5inch tip. I will use a Type RS Greddy blow-off valve, a HKS 38mm external wastegate. I will use a front mount intercooler and 2.5inch piping. I will use the Ford EDIS ignition system to trigger my ignition timing. I will use Magncor KV85 ignition wires too.
My CT20b turbo is for sale here :
I have for sale the stock intercooler and the stock ST215 differential
The fabrication of the manifold and the downpipe will begin after Christmas. Everythingelse is set. I’m suppose to put the engine in beginning of March. It will be ready for this summer. I plan to reach 320hp to the wheels at 16-17 psi of boost.
Finally, I hope this file helped you to know more about the ST215 engine. As I think, It’s a nice engine and I don’t know why people dont like it. They prefer buy a ST185 one and buy some bolt-on aftermarket parts. For me, I prefer a newer engine than an older one with 5k$$ of aftermarket parts.
