4efe or 4afe box + 4efte in a Corolla E11?

I can see you needing the CT9 pipe from a 4EFTE kit but the rest will need to be longer as the nose of the car is further forward.
Exactly. I’m going to have to cut a pipe from scratch and go around the engine when it’s mounted.
What about the water cooling pipes from the radiator? apparently the holes in the engine are different and I don’t know if the Corolla pipes will work with the 4efte.

The guy from Greece who did the swap just told me that pipes were custom made by his mechanic and better get a 55 mm diameter to avoid Turbo lag. he says that 63 mm are too big for the stock fte.
what do you thinkabout it?

I was just told that the holes for the water coolant are the exact same in both fe and fte engines so my custom pipes from the radiator will fit perfectly. This is a good news.

Your coolant hoses will be longer than the Starlet version so the 4EFTE ones won't reach your radiator. Take a good picture of your current hoses, most notably the points where they connect to your engine and I can advise properly rather than guess. Will take a few comparison pics of a Starlet to see what your best approach is.

I'd treat that with an ounce of caution.

Even the 4EFTE has two different lower hoses available depending on the thermostat housing that is fitted.

Take the pics and we can work the best way to sort it.

Whilst I agree the thinner pipe is preferable on the hot side (turbo to intercooler) you can run up to 2.5" quite happily on the intercooler to inlet manifold.

I've seen a few different diameters used (and some interesting reducer hoses) and the CT9 isn't overly laggy tbh. Even on extended piping routes.

Will do.

As you can see in the diagrams, the Japan Starlet ep91 and the European Corolla E11 have the same radiator and hoses.

They don't look the same hose.

FYI - The 5 digit numbers you are looking at on the main diagrams are only the identifier number. You need to use the 10 digit part number to confirm if they are actually the same. Even one digit out could make them totally different.

Also the hose in the last diagram pic is at the rear of the engine so isn't related to the radiator.

From your pics I can see two things

1) the top hose on your engine is longer than the 4EFTE but connects in the same spot. That means you should be able to use it to connect the 4EFTE to your current radiator.

2) the bottom hose connects to the engine differently than the 4EFTE. Your current outlet on the thermostat cup points forward towards the radiator but the manual 4EFTE points towards the battery making it 90 degrees out. Fairly sure you will need to put your current thermostat cup onto the 4EFTE thermostat housing to sort this. That should let you use your current bottom hose too which is encouraging.

Heres a manual 4efte to compare.

You can see the two coolant lines for the turbo in that last pic. Your 4EFE doesn't have these.

The automatic 4efte has a different thermostat housing that points forward but that's by the way side.

Sounds like we sorted it out! I love when a plan comes together :)

Bear in mind it's all theory until you prove it by doing it :)
Immagine I am paying a £1600 4efte without gearbox €2600/2800 that includes shipment from the UK, import taxes and VAT 22%. No way to get the engine straight from Japan here. The guy I was talking to seems to have trouble finding it. It’a a loopt of money.

Think my intake side is 2.5 and hot side is hdi pipes for a GT/Glanza, think they are 2 inch will check tomorrow
The gt-four was 3 inch both sides, another part I should have kept.......

Aren't you considering a different swap? Something like a Honda engine swap? Ever year more parts get discontinued and Toyota most likely won't put them back in production like some other car brands are currently doing with there cars from the 90s. You may wel be trying to swap something into your car which will soon contain a lot of discontinued service parts.

What engine are you talking about? Hope nothing electric.

A honda b18 engines would be a noption. Most likely it would cost even more than the 4efte. I would look into every possibility of using your current engine and get a td04l or something like that on your engine. The ct9 is going to be very hard to service soon, while the td04l is a very common turbo and will have a supply of parts for a long time.

The management part is going to be a challenge but the 4efte you will be swapping in is very old and will require so much work it may not be worth it. For the same money you can forge your current engine and get lower compression pistons to run boost.

Focus on future support of parts instead of something that is now possible. The 4efte is a swap which is currently possible but I doubt maintenance for it wil be easy 5 years from now. Forging your current engine with custom exhaust line is going to be the best bang for your buck in my opinion. The cost for the front mount intercooler will be the same for the ct9 and tdo4l.

I partially agree with you because for what I have learned so far about turbo charging the 4EFE, The pieces to buy and adapt would make it cost much more than the 4EFDE swap. If I have to spend so much money I would rather buy a new car. Most of you guys talk like we all have a shop in our home with all the tools to modify pieces. Unfortunately it is not true. I don’t have it and I will have to pay for every piece to be modified for the water and oil lines, inlet, outlet, sensors, Stand-alone ECU and turbo installation without considering forging the engine that only costs €2000. On top of that is the labor and the risk that it won’t work. Not even if I keep the original compression and run 0.5 bar boost. So far only guys in Australia did it smoothly. I met a few guys on Facebook that are confident but they are not gonna do the job themselves so the risk is too high. If you have the perfect recipe or a guru that can give me a list of parts and prices I will be more than happy to consider dropping the swap idea that I worked for six months on.

I thought we worked through the whole 'buying another car' thing a few pages back lol.

In terms of FMIC piping aim for 2" between the turbo and the intercooler and 2.5" from the intercooler to the throttle body.

Don't think of the intercooler and pipes as one big free flowing system. Think of the intercooler as a large chamber that the warm air gets cooled down in then fed to the engine via the cold side piping. It's a large reservoir not an air filter if that makes sense.

The throttle body is 2.5" anyway so you may as well get as much cooled air into the pipe as you can.
