1.9 TDI Discussion

[Redgoat]

Just curious if anyone has done this. I know Greg mentioned it in another thread, and I have had a friend/mechanic suggest it as well.

Has anyone tried doing the 1.9 TDI long block and going to a 2.2 liter setup?

What all would you need for this? I know the fueling is obviously different so it makes me wonder how and what you would need to swap out on the head. I dont think the heads on the 1.8 would match the 1.9 TDI or be sufficient enough for the 2.2 conversion. But I am not sure.

Figured it would be nice and informative to open a thread up for discussion of this.

Might want to talk to the B5 guys, or even Issam.

Good luck finding a block for a reasonable price...

[Redgoat]

Makes me wonder if the ALH block would line up.

[SEXICÄN]

you wonder too much...

[Capt. Obvious]

You'd pretty much need to a complete drivetrain replacement. The gearing in the gas-powered models is too high for the low-revving TDI's. Not to mention the fueling system, ECU and all other components. Basically, you'd need a fill donor car.

I believe he's saying he'd use the block and lower rotating assembly from a 1.9TDI and using a 5 valve head. I also believe he's looking for a way to build a bigger "1.8t" than the 1.9 and 2.0 builds than have sprung up lately.

I wish I could find a ALH block for cheap

Exactly!! I was thinking block and head.. bored out to a 2.2 With a MUCH BIGGER turbo

Just not sure if the engine would bolt up.. what you would need for the fueling system etc.

I would think that the driveline would hold up.. I mean heck, if it can hold up to the bigger power of the 2.0 BAT builds.. then it "should" be able to hold up to a 2.2 bigger turbo build. Just that the block being bigger on the 1.9 would be more suitable for bigger displacement. I am not sure though if the 1.9 head would flow more.. or if the 1.8 head would even bolt up to the 1.9 block

Whats considered cheap?

Even cheaper short block

[Groove1797]

The question is will it work

[Redgoat]

exactly what I'm wondering..

Reading other posts show that even the crank from a Automatic 1.8T to a Manual 1.8T is different.. so who knows.

[1point8teeNW]

Well consider this.

The VW'ers use the 1.9 crank in the 2.0 ABA and use a 16 valve head.

we'd have to be 1.9 crank in the 1.8 block with 20 valve head only if the 1.9 block woudn't work for some reason.

[Redgoat]

the main reason I am wondering this is to go to a 2.2L setup where as the 1.8 block is pushed to its size limits (safely) when bored out to a 2.0 .. so we could get more displacement with a 1.9 block to start out with.


Now granted, if this does work, it might be cheaper easier instead of building the engine to a 2.0 to do a 1.9

I am not a mechanical engineer by any means and don't possess a lot of knowledge when it comes to these things. So this is all just kinda thoughts and speculations.

Eurospec sells a 2.2. It uses a 1.9L TDI block with 100mm rods IIRC. A 2.2L would be $ with a 35r. It's 16mm taller then a 1.8L block but they say everything bolts up without issue. If I were to do it again, I would have had David build me one.

[Wizard-of-OD]

Send me a PM to discuss this further.
Thanks

[Redgoat]

cough... $6,890 ... cough

[Redgoat]

Send me a PM to discuss this further.
Thanks

PM sent

[dirtybrd]

I didn't say I'd buy a Eurospec motor but they sell them. Call David @Eurocode, or talk to the 034 guys.

I have tried Numerous times to try and get in contact with David with no luck at all. I sent a PM to Issam, so hopefully I can get some answers

[dirtybrd]

How did you try to get ahold of him?

[Redgoat]

email

[dirtybrd]

Are you really serious about building one?

[Redgoat]

More curious as to what it would entail etc.. its kind of a pipe dream right now.. but it will vary on cost etc. So I cant say at this time whether I am serious or not. It all depends I guess

[Redgoat]

I figured if we could get a thread going with enough discussion/details about it that it could be a possibility for others as well. Kinda like an alternative to the 2.0 Stroker

[dirtybrd]

I just got off the phone with David and he said the longer stroke of the 2.2 really kills the ability to rev. the motor and suggests just building a high revving 2.0. But said if you want it, he will build it, price was not discussed.

Good to know. Thanks for that!!

[Wizard-of-OD]

You can rev a 2.2 stroker motor.The bearing failure is a myth....that just keeps coming up month after month....

2.2 20V - aint she sexy?

[Redgoat]

That engine is pure sex!! What are the plans for it?

[AudiA4_20T]

Hey man you can make a 2.1 with a TDI crank and custom pistons. You would keep your block though, might want to do that instead, youd save a lot of $$

[Redgoat]

I thought 2.0 was about at the limits ... hmmmm

[dougyfresh]

Told you to talk to Issam

[Wizard-of-OD]

95.5mm crank in the 220mm block produces a 1.50 rod ratio.Too small for what he wants to do.
