Team FNT – ABARTH 1000 TCR MOTORREVISION | 1000ccm HEMI!

Today we have a review of the engine of a Fiat Abarth

1000

TCR. Here is our car, which you may know from our YouTube shorts. Our "little chubby". This video wasn't really planned, but the car received a new overhauled engine and we also reconditioned its spare engine. Just take a look, it's a different video from the others we usually make. This time there is no Japanese car, nor Toyota, but I hope you like it anyway. Take a look at how I'm building the engine. This is an original AH engine block. Here on the side you can see it.

It is something very special and rare. It is one of the last ones produced, you can see it here, it has this small bridge over the water pump. It is the latest specification of a Fiat Abarth

1000

TCR. Not only is the block different from the 1000TC engines, but also the crankshaft and connection. the rods are different. The R in TCR stands for radial, it has a

hemi

spherical combustion chamber, which Americans are very proud of, they are always proud of their HEMI. Fiat Abarth already had a HEMI in 1968. I can show you a cylinder head, also called a four-channel cylinder head here just to show this ugly old one.

It's from a production vehicle, I think it's from a Fiat 600, it could also be from an Autobianchi or a Fiat Panda, everything was very similar. You see this little entry here, in an Autobianchi you have put a 32 register carburetor up here. Here on this TCR you can see a four channel head with four inputs. It is for two twin Weber carburetors. Here is the intake bridge. We also checked the carburetors recently and they were on the shelf. This is something that kids had a lot of fun with in the late '60s and early '70s.

A Fiat Abarth 1000 TCR was the car par excellence at that time, in the 1000 cc category. The most famous German driver in this category was Johan Abt. He was the father of the two Abt brothers, Christian and Hans-Jürgen, from Kempten. Johan Abt, as far as I know, won almost everything in Germany in the 1,000 cm category. This is a stock cylinder head. The interesting thing is the combustion chamber, it's all dirty, we could throw it away. You see the valves stopped, the pistons are flat on the bottom. You can see that the valves are very small. If you compare it with the TCR cylinder head, which is something really expensive and special.

You see, they are V-shaped, with a spherical combustion chamber. As you can see here, the pistons also have a special shape, here there are pockets for the exhaust valve. It is a pure racing engine, very rare and difficult to find today. There are also some good replicas on the market, which you will also recognize and are almost identical to the original, but also the replicas are expensive. You can see the rocker shaft here. The pieces are also reproduced with high quality. We are lucky to have an original engine, which we are inspecting. The engine was completely disassembled.

It is freshly polished. As I remember, the pistons received a graphite coating, we balanced the crankshaft, it had a slight impact so it became unbalanced along with the flywheel. Bearing set, thrust bearing set, everything has been checked and modified slightly, as you can see, we are doing the last steps at the moment. The cylinder head has been calibrated. The valves have been slightly ground and pressed with the vacuum device. Now we will replace the cylinder head and adjust the valves. I have to adjust some things on the rocker shaft. We will replace the side springs with aluminum sleeves. because in the past these springs deflected due to high rpm.

When this happens, the valve would be open and this could cause engine failure. That's why we'll change it right now. This engine can rev up to 8700 rpm. With its 1,000 cc it had, according to Abarth, 112 HP. In its time it was a high-tech engine. It was a purely sports engine. In a way, a little bit Ferrari, something really special. The carburetors have also been recently overhauled. Those are the originals from yesteryear. The difference is that the originals are written made in Bologna, later it was written made in Spain. 40 DCOE carburetor An original motorola alternator Magnesium oil pan and here you can see the

Outlet, inlet, now we adjust the valve clearance. I think most of you know, it's an old school car. It does not have hydraulic lifts or Vanos. As most of you probably know, the engine starts. that's how we met him at school. The first cylinder is on the opposite side to the power output side. Here's our steering wheel, so it's opposite our power end. so this is our first cylinder and this is the fourth. Now we see the overlap. You can see that the inlet valve closes completely and the outlet valve wants to open. That means we can now check the valve clearance on the opposite side.

Here we have an exhaust valve clearance of 0.3mm and an intake valve clearance of 0.25mm. I adjusted it a little before, of course, now it's a little tight. I even found an original Fiat tool, because my father worked at Fiat many years ago. We raise it a little bit to see how this 0.25 passes over here. This means we turn this screw here. The same procedure that we will do on the outlet valve, we open it a little. Lightly sucking that's how I learned it back then. It should not fall, a feeling develops. If something rattles, you can still adjust something, because everything has to calm down a little.

The Autobianchi, engines of the Fiat Panda, were also known as rattle engines. These engines were of similar construction and were known as rattle engines. But that was more of a problem with the distribution chain. We will adjust the 1000TCR later. Then the valve cover goes here. which already comes prepared with the seals. Then we put a distributor and the beauty is ready. Then there were two escape options. One of them had a normal silencer, which comes out from the bottom. This version was called an oxtail escape. Later it will be assembled like this. And then the exhaust gases come out through the open hood.

It will still have a ceramic coating to keep it looking good. Now we'll go to the car so we can show you the engine. We are in our garage where we repair our normal cars. Our normal cars with doors and roofs don't look like the F1 cars we have. Here we see our little Fiat. We check the entire engine. You've seen how we overhauled our booking engine. The reserve engine is the one with the red engine block and this is the engine that we will build in it has a gray color. Maybe there are some small differences with the red one, but it is also a real TCR engine.

Four channels with Hemi combustion chamber. But I already showed you that before. As I said before

1000ccm

and 112 Hp. We didn't compress our engine as high as they did back then. Back then engines had a compression of up to 12:1. Thanks to a thicker head gasket we have a compression of 10 to 1, very similar to that of an Autobianchi tram. Then we will go to a dyno and I hope we will have around 100 Hp. Everything is prepared and now we will install the engine. We have now installed the engine in our little Fiat. You shouldn't call it Fiat because the Abarth guys insist on calling it Abarth, but you know what I mean.

We warmed it up before changing the oil. Now with the right oil I hope the engine starts and is ready for the Mugello race track. We'll see. Turning on the fuel pump, then we can go back. A start button is also installed here, which is quite simple for mechanics. No one should tell us that we can make Japanese cars :-). Now the car is ready for the test bench. We have installed the second hook, which is for fixing it on the test bench. At the front you fix it to the front axle. On the back you have the hooks.

And now we will see how it will work. As you may have seen, the car performed exceptionally well on the dyno. Everything works perfectly now we will go out to the race track. The red engine is also done. Now we will go and act. If you have any questions about our little Abarth, write a comment. I'll try to answer it. Bye, have a nice day, see you next time!
