1Z to AFN Engine Swap & Performance Upgrade

Hello everyone.

I once contacted a tuner about increasing the power of my 1Z engine. He mentioned that it might be possible to convert it to the technology of an AFN engine and then use the company's performance kit.
He suggested two options to me.
I received the following list of parts from him that are needed:

Variable Geometry Turbocharger 17.
Fuel injection pump.
Control unit.
Manifold.
Nozzle 205.
Chip.

max. 160 hp


Also, add a boost pressure sensor.
'Hybrid charger available for vnt17.'
12mm pump pistons with chip.
Exhaust system, group a, 63.5mm.
Nozzles216


Up to 200 horsepower, depending on the Russian version.


What do you think about it?
Has anyone here ever had experience with something like this?

Best regards,
Olli

Hi,

The tuner seems to be unaware of the actual differences between the AFN and 1Z engines. In addition to the listed components, there are also minor details such as the piston cooling system, different materials used for the engine block, and other "minor" variations.

Furthermore, the VNT17 is a VTG (Variable Turbine Geometry) turbocharger, while the turbocharger in the 1Z is a wastegate turbocharger. The control system is also different, which means there are even more components involved that haven't been mentioned.

I would have serious concerns about such a "tuner," especially if it's trying to extract 200 horsepower from an engine that was originally designed for 90.

Best regards,

Jan.

The engine block was the same. The 1Z also had piston cooling, if I remember correctly. However, other internal engine components were different (I mean, those were probably bearings).

Hi!
The main engine block is the same as in the 1Z engine. However, the engines differ only in the pistons! I don't know what's different about the pistons. But according to the parts catalog (AKTE), the bearing shells, crankshaft, etc., are the same parts for both the 1Z and AFN engines.
Best, Timo.

So, just the pistons?
I'll ask him what's going on with them.
So, has anyone here ever had any experience with something like that?
Unfortunately, I don't know anyone who drives a modified TDI like that.
But thank you for the answers so far; it would be great if someone else could add something.

Best regards,
Olli

@ Olli:

What do you actually want?

The description sounds almost a bit like 'we can only use AFN.'
'First, we need to convert it.'

Best regards, Rudi.

@Pred
Don't forget the transmission, clutch, and brakes.
With a Z1 turbocharger and 160 or 200 horsepower, you won't get very far.
You could then change your tires every week, as long as your clutch or transmission doesn't mind.

Best regards.[/quote]

@ Rudi

I'd really like to get a bit more power out of the 1Z engine. And I want to do it without significantly reducing its lifespan. That's why this 'Umabu' thing sounded quite reasonable. Definitely better than installing a chip and extending the injection time, or something like that.

I found a link in this forum for a tuner that can increase the AFN engine's power from 180-200 horsepower by modifying various parts.
I then emailed him to ask what was possible with a 1Z engine. He replied that it could be brought up to 200 horsepower if it was converted to the 110 horsepower version.


I already went to the TÜV (German technical inspection agency). And they said that the rear brakes should also be disc brakes.
I haven't heard anything about the transmission yet. I thought the one from the 1Z already had such a long gear ratio.

Best regards,
Olli

Hmm...

Do you want 180 to 200 horsepower?

According to my understanding, increasing the power output to around 120 horsepower would be a reasonable goal for the 1Z engine.
and 140 hp with the AFN engine - with a different turbocharger and different injectors.
'It also has a 'healthy' 140 horsepower for the 1Z engine.'

Everything that follows will be very expensive (ESP, pistons, connecting rods).
Clutch and transmission that can withstand the torque.

Best regards, Rudi.

The AFN also has a different exhaust system - and that's another 1000 euros gone.

If money isn't an issue, why don't you just buy an AFN and modify it to your liking?

m;

Well, but what is the price of one AFN?
Around 4000 euros, or something like that?

That's actually a bit more than the approximately 1000-1500 that I'm supposed to pay.
It's not like I'm swimming in money.
I just wanted to know if this would also work with the 1Z engine, since the engine itself is supposedly mostly the same as the 2.0L, except for the pistons.
That's why I assumed that it couldn't be that much worse for him than it was for AFN. Or am I mistaken?

Hello Olli,

It seems that your tuner and you have seriously misunderstood each other .

Nozzles: approximately 400,-.
Control unit (eBay): approximately 100,- (unless you already have an MSA15 installed; i.e., production date from April 1996 onwards).
Turbocharger: approximately 1,100,-.
Exhaust manifold, approximately 130,-.
Software customization: approximately €400 - €1,000 (very rough estimate).

Um, that's already well over 2,000 euros now...

Best regards, Rudi.

Hi!
It's not a problem at all to get 200 horsepower out of a 1Z 180 engine!
'0.216-inch injectors, 12mm pump pistons, and good software! That's all you need to get 180 horsepower! For a larger power increase, you should consider installing a different turbocharger, such as a VNT 17 or even a VNT 20. However, this will require modifying the turbo control system, because a VTG turbocharger is controlled differently than a wastegate turbocharger.'
Best, Timo.

@ Timo

The items you listed are also available in the dealer's inventory, so it should be possible to get them without any problems.
'My main concern is to set it up in a way that the engine can handle it. That's why I'm reaching out to you all in this forum, because I can't assess whether my engine will be able to withstand it. Of course, there's no guarantee that it will last.'
I had assumed that with the right components, such as a VNT 17 turbocharger and 0.216 injectors, the wear would not increase significantly.
I don't want the box to fall apart!
But it seems the general opinion is that it won't work out well...

Tough decision!

Hi!
'In another forum, some people are doing this without any problems so far! A sports clutch is definitely recommended! Any tuning will affect the lifespan if used improperly! If you constantly rev the engine in cold conditions with the tuning, do burnouts, etc., things will break down quickly. The engine and transmission are not designed for that!'
If you start it when it's nice and warm and avoid sudden, forceful starts, the engine will run forever!
The AFN wouldn't stay up any longer!
It's ridiculous to first convert a 1Z engine to an AFN and then throw away half the parts to tune it again!
Best regards,
Timo

PS: The complete 1Z tuning package will cost you approximately €1000-€1200. Converting only to an AFN engine would cost significantly more!
