Assembling the 4a-ge 16 engine based on the 3a-u block - Toyota Sprinter Trueno, 1.6 L, 1985
removing the engine
we look at it for the last time and remember it as a misunderstanding
everything, the engine was removed from the car, then a complete disassembly followed, removal of the head, pallet, crankshaft and piston, I had to purchase one head separately, it stood on the rear-wheel drive crown, which was installed on block 3a, the second one I got together with the block from which a knee knocked from ae92 Levin, I also purchased a piston with a crankshaft from 4afe in excellent condition, it was not possible to use Levin's giblets, the seizure was too large, the piston was washed with Amway household chemicals gel for cleaning kitchen stoves from carbon deposits
heads
piston
after a complete disassembly of the engine, it was washed and taken to the borer
who bored me a block with 77.5-77.0 for geometry 4a pistons 81.0-77.0
further assembly of the engine on a bored block, with a crankshaft and a piston from 4afe and a 4age 16kl head.
final version
and finally, installation back to the body
it is worth mentioning separately about the electronic component, I got the wiring in a cut form and it was pointless to restore it, boldly cutting it into plugs began to create it from scratch, it was a real akhtung
at the moment the wiring is ready, rang out and neatly laid in the body, all components
are hooked up, it remains to unsolder the diagnostic block, send the SPD signal from the instrument panel, install the fuel pump, and resolve the issue with the generator, which in the 4age ae86 design is located on the intake side slightly lower than in front-wheel drive versions, I decided to leave the generator from the 3A engine in its original place on the exhaust side
well, while I am doing purchases for the winter, but physically I am not doing anything with the car, although I will soon go to buy bends for cooking the turbo collector

tell me please! I have a Toyota Corsa 1981 faced with the problem of engine repair! no spare parts for sale! will fit from the 4a engine? volume 1.5
I know for sure that the calender from 5A rises because in my 3A it is.
It depends on what you need, I can find out exactly what gets up and what doesn't!
for 4A, the volume is 1.6; for 5A, 1.5 is the same as for 3A.
if the motor is 3a, then you can easily take the crankshaft and connecting rods from 4a / 5a from it, which is essentially the same

just bored the block up to 81 mm and didn't sleeve it?
and how much wall thickness will there be?

4e-fe will not work, you still need to look for 4A / 5A-FE
I got such a motor, it lay for almost a year, right now my engine is dying, I want to collect something on this block. at the weekend I will sort everything out and measure it, I hope for your hint on how best to do

maybe such an engine will cross the road, but I accidentally got this one for 5 kopecks
while the engine has assembled 3A, then I waste it, I don’t know, carb for 4A or some kind of injector thread, there is 4EFI engine for analysis
here is an interesting topic about the engine! alteration to 16 valves is already really interesting)))
buddy, what box do you have? And if you just take the 4A-GE engine assembly, will it get up with its own box?

Hello, tell me, please. I'm interested in the possibility of installing a 20kl head on a 5A-FE without changing the geometry, in theory everything should work, but it's still better to ask you.
As far as I understand, I will need: a
cylinder head plus the entire intake, a blackout map, a distributor with wires, a coil and a switch.
Exhaust manifold, front pipe, lambda.
Brain scythe and generator from black, still gur from it.
What else might you need?
On my 5af engine, the pistons were less than 4af in diameter, which means that you need a block 4a and pistons 4age with cicovka for 5 valves, otherwise it will bend them. Further, the knee 5a is smaller in diameter (neck) reinforced by ge and the piston pin by 20 instead of the 18th 4 and 5 afe from all this it follows that 20v cannot be put on 5a but can be muddied to 4a and 7a with replacement of the piston and other steam.
I collected 7a ge with 16v now I'm finishing it all (there are a lot of parks in this case), let's see what happens!
Hello, actually everything except the block itself, head, inlet, outlet, and all electrics from 4age20

Hey, what do you think if you buy a fairy head and leave the carb on? So the crap is less, there is a 4a-f engine, a carburetor, 16 valves, I did not see the visual difference from the head
well, the whole motor, according to the price list, will be somewhere around $ 500,
and I found a lot of head variks from 4af at a price of $ 50 to $ 100, attachments to it don't seem to cost much money either, so I thought
Yes, you can, the A series blocks are essentially the same, it's easier for you to take the whole engine, it is inexpedient to assemble an injection based on yours for money
Hi. I have been
looking for information about replacing heads on such engines for a long time, there is not much information) You, as a knowledgeable person, want to know this.
There is a 4a-l engine, 8 valves, carb. Will it be possible to put his head on it from 4af. If so, what else will need to be supplied (injector, brains, what attachments)? Thank you
It turns out that you only need the pistons 4a fe or ge and sharpen the block? There is just a motor for disassembly 4a ge red top, 40 tr. they ask for it, the toad presses me over the cat in the sack, but they can sell the boss with the scythe and the computer separately. I'm thinking how to make it cheaper ...
Greetings. If assembled on a first generation piston 4A-FE, the compression ratio will be less than 9.4. It is not an option to put a gasket from 7A, at high speeds the piston catches up with the valve. What is your compression ratio?
What are the nuances? With the flow of cpg and boshka from the chaga SZ norms it turns out? Where to get the cylinder head gasket from?
it is possible, which one does not matter if we are talking about a bigport, they are identical
Hi, is it possible not to change the CPG, just throw on the boss? I think to collect in January to try
And in the end, which one is better to take from the PP or the RFP of the car?
hello, if you put your head from 4age on carbach, which canopy will fit from 3a?
Hi, we need cooling tubes from 4age, move the generator to the other side, come up with something with ignition, the distributor from 3a will not work
