Hi guys.

i swapped the engine and there are issues to fix. Communication between dasboard and ECU/sensors like RPS signal, alternator doesn’charge, engine check light on. The car doesn’t start at first ignition. It need several cycles before it starts running. The problem happens only when you leave that car off for 24 hours. Any help?

Does the charcoal pirge canoster regulate (eith the vacuum pipes conneted) the return fuel pressure? It seemes that the car doesn’t start immediately in the morning without it. Probably because the fuel pressure goes down without it? Any help to solve it?

Do I need a vacuum pump (not the oil pump) to make the 4efte vacuum system work properly? I swapped in a Corolla E11 and I am trying to fix all gaps. Thanks.

This may be your coolant temp sensor if the cold starts become an issue, I chased bugs out of my car for a year solid and seeing as it was my first starlet I didn't have much knowledge. but once I changed the sensor she was right back to starting on the first turn in the mornings

You are right on the money Berty, from what I remember Frankie found the wiring for the temp sensor was an issue in another thread. Think he's got it sorted now.

Exactly my friend. The guy who did the wiring bridget tge water temp wire with a 5V close to the ECU and this caused ECU recovery. As soon as I found the bridge and I got rid of it it all went back to normal. This was the main issue with the wiring loom. The other big work has been getting the air conditioning working. I sorted it out by myself with the help of my brother using in oscilloscope. At first the guy took the signal do the air conditioning computer from the alternator. The same signal was sent to the cluster RPM that was jumping. We sorted out to issues in one. Changing the cluster resistor to a smaller one made it work as the cluster needs at least 3.5 V and the stock resistor was a 5 V. We sent the same square signal to the AC computer and the AC started working. Now I can tell that the car works completely fine. The last thing I will do when I install the DET 3 will be to add a switch to the Low/High boost wire that was cut as the Corolla doesn’t have that function.
before I check out the wiring diagram you guys could tell me which wires go to the high/low boost with the signal from the ECU. The solenoid is in place. I just need to wire a switch to make it work.
I still haven’t found anyone who has used a DET 3 on a 4efte that could give me a base map.
I need the basic DET 3 setup for the engine to be able to use the car and drive to the mapper shop.
The hardware that I chose is a relocation ct9 turbo kit with external waste gate. I chose to keep the stock turbo because I want to boost at 2500 RPM. No td04 for my daily drive needs. I will have to clock the turbo 90* facing the floor, relocate hot pipe and FMIC input pipe. I will also have to cut and weld the AC lower pipe to get it out of the way from the radiator area. I will need that space. The turbo air filter input will have to go where the window shield water tank is as the new exhaust mani will take efi space.
Let me know what you think about it!C53BD48F-55E3-4079-BF70-72E1758716E8.jpeg8C942004-B0C5-48FF-A00B-18AC50A1239E.jpegD4CA4C09-0D74-44D9-BB88-F42ECEEF0EC5.jpeg2501DA8F-B401-4114-8732-AAB6C5329AB5.jpeg11CB9BF1-9F12-4731-B221-2D387C14E7D8.jpeg7CB2D909-8CEE-48D2-B26C-E2ECB35FA037.jpeg

P.S. I bought a HKS SLD to get rid of the stock speed limiter but I don’t need to install it because the DET 3 has the same function. I did a post to sell it on the forum. If anyone is interested!3953986C-5A2B-4D7C-B9EB-DFAEE285D859.png

I have been lurking these forums for a couple days as I've been looking to turbo my 4E-FE. In my country, I don't have easy access to the 4E-FTE that UK people have so, more power is either the 4A-FE or turbo it and I choose turbo everyday! :cool:

Nice to know people still post in 2022 :D

Congrats on the build Frankie! Looks sick

We are always happy to meet people like you that have the same passion. We love these cars because they are alive compared to the new generation of car is that have that annoying thing called obsolete programming.
Anyway I suggest you to turbo your engine the right way because a 4AGE or 4AFE Will not give you the same emotions.

Yea, I had a 4AGE in a AE92 before and while it's a good engine and car, I feel like this will make me a better car enthusiast haha

At the moment I was looking at exhaust manifold, injectors, con rods, turbo ofc, intercooler. Still need to know how much different are the pistons and crankshaft.
I'm not really looking for crazy numbers on the engine... I just wanna go from 88 to 120 possibly.

Since you have experience on this matter and since a TD04 is much easier to find, is a TD04 that much bigger of a turbo? I've seen in your post that CT9 boosts at 2500 while TD04 probably has a lot more lag on it, correct?

Cheers!

I hear you My Corolla had a 4efe with 86 hp. 1000Kg car needs more to move! The swap project was ambitious. I did a 6 month research to find out whether it was better to turbo the engine or swap it. I made a list of parts I needed and it ended up being way more expensive than buying the full stock turbo engine. It all depends on your experience with mechanics, with these engines and of course your budget and effort to bring in custom parts to make a unique job. So far we did an amazing job but besides getting the cylinder head off and bringing it to weld because of a crack and replacing the valve ceilings, we didn’t open the lower engine block to replace rods and pistons for a stage B engine. This because of the budget and because I want a daily car. I spoke to people that put the turbo modifying the 4efe and of course it took a long time and a lot of effort. The main topic is creating a metal gasket to raise the head and get 8.5/1 ratio from its stock 9.2.
Then you have to find the map sensor and of course you can get companies build whatever you need but when I found out the prices I got scared. This is why I decided to start from a stock turbo engine that would work and eventually upgrade from there.
