AHU with 0.205 nozzles

Since I'm currently considering having the 0.205 injectors installed on my AHU engine, I wanted to ask how the engine will handle it.

I've read a few posts already, and generally, there don't seem to be any problems. I've also read the report about "1Z engines with 0.205 injectors." I'm just curious about what the major differences are between the AHU and AFN engines. Are those just the nozzles and the VTG turbocharger, or are there other components as well?

I plan to drive the engine for at least 300,000 kilometers. If I install these injectors, should I expect a significant reduction in the engine's lifespan? I always warm up the engine properly and rarely drive it aggressively. I'm mainly interested in the car's acceleration.

I know this topic has been discussed a few times already, but I prefer to be a little more cautious with things like that.

hi

There are still some detailed differences between AHU and AFN, but there's a separate thread for that.

The AHU will work well with 205s. It will stretch comfortably.
When you compare it directly, a standard 1Z engine (which is the same as the AHU) seems "very restricted" in its performance.

You can notice it both when accelerating from a standstill and when driving uphill on the highway.

... and about a dozen other components!

I'm referring to technically relevant parts, such as connecting rod bearings, crankshaft bearings, etc. Not that, for example, the flexible duct is designed differently, or that a different screw is used here compared to the AHU.

It's almost exactly the same, you know.

Hi.

As I mentioned, the differences between AHU and AFN engines are the subject of another thread and aren't really related to the 205 injectors in the AHU engine.

According to. The shop expects an 8% increase in performance, which the rest of the engine can handle, and it does.

I can only view the upgrade to 205 injectors on the 90 hp engine positively. I've been running 205 injectors on my car for about 25,000 km, and it simply feels more responsive. I can't identify any disadvantages!

"Back then, it also had almost 50,000 km on it. The 1Z engine is like new. It pulls better and even runs more smoothly (although I attribute that to the old, worn injectors). It suddenly reached almost 210 km/h on my speedometer (198 km/h according to GPS), whereas before it was only 180 km/h on the speedometer..."

After receiving only positive feedback, I already know what I'm going to have done this summer.

However, I intend to leave the engine as it is for now, hopefully until its eventual end, which I hope is far in the future.

Can I send in my old 185 1Z injectors here and get 205 injectors in return?
And how long does one have to wait for their nozzles, and what is the total cost?

Sure, here's the translation:

'MFG' is an abbreviation for 'Mit freundlichen Grüßen,' which translates to 'Sincerely' or 'Best regards' in English.

It's all explained in the product description on the shop's website.

Your previous nozzle holder combinations must be sent to us, and we will send them back to you, regenerated and adjusted, within 2 business days.

Read _and understand_ the user's manual .

Hi Wurstblinker,

Please send all inquiries regarding the shop via email to shop@dieselschrauber.de or through the contact form on the shop's website; I only saw your message by chance.
The nozzles are in stock in sufficient quantities, and the conversion will be completed within one working day.
So, with shipping, the delivery time is a minimum of 3 days and a maximum of 5 days.
The nozzle holders are also available for exchange, with a deposit of 300 EUR. This deposit will be refunded upon return of the old (functional) nozzle holders.
Please contact me via email or private message if you are interested.

Best regards, Rainer.

I would like to do the same modification, as my nozzles already have over 150,000 miles on them.
Use the designated area near the fuel tank for operation.

Thank you.

Luksa.
