TDI/2.0 Build Questions

[smittywerb]

What's up vortex. Got some quick questions. I'm doing a little project with my mk3 at the shop and I came across a build that I wanted to try. Basically I have found out that the turbo manifold and turbo charger from the TDI bolts on. Now I am aware that the TDI turbo only works at lower RPM's but I am only trying to build a fun daily, not a monster (yet, I'll be doing that with my VR6).

What I want to know what are the risks (if there are any) of running this build? Will using the TDI turbocharger and manifold on my motor cause anything to go wrong? What do I need to know?

And the parts that I need for this build are the turbo charger, manifold, oil lines, g60 injectors, intercooler, and fuel regulator pump. If I am missing anything please let me know. Thank you guys!

TDI turbo on 2.0 ABA = good torque up to 3500rpms, then it runs out of breath and you're left hanging with a very weak 3501rpm-redline.

Hope your clutch and trans aren't beat already because they soon will be.

I figured the Turbo would only work at low rpms, but why would did you mention the trans
and clutch? I know that turbos put more strain on.the motor, but is there something about this.build.that would.cause it to wear down the trans and clutch quicker?

depends on how you drive...

This is my daily that I am doing this build with, so that means the fastest that I would be driving is around 80mph on the highway.

the stock ahu turbo (gt-15) is a waste. go with a vnt-17 instead. the vnt spools faster and will handle a bit more mid/high rpm boost for a gasser.

i think this turbo will bolt up, but don't quote me.

Thnaks jstn. That was going to be my next.question.

Hello,

That's not quite a bolt-on affair. Most VNT turbos will hit the rear engine mount unless it's been modified. The only VNT-17 I've seen clear the rear mount is the two-piece unit made for the B5.5 Passat.

I've been considering a VNT-17/22 swap for a while. But I also have my eyes on IDParts' GT2052. Either swap will require exhaust work. But the GT2052 won't require VNT conversion or a special program. I could probably run it without a new tune at all. I KNOW I can at least drive it until I get the tune. A VNT NEEDS a tune.

A true bolt-on option to consider is a K03/K04 hybrid from BoraParts.com. With the right tune, exhaust and injectors, I've seen one spin 149-whp and 312-lb/ft (dyno-dependent, right?). It also ran 14.7 @ 93-mph in the 1/4-mile. I've only managed to get 136-whp and 263-lb/ft. My best 1/4 was 15.3 @ 89-mph. I think I can do better with the GT2052.

Scott this is for a 2.0 gasser so I'm absolving myself of any knowledge related to interoperability of parts and components... however your observations are correct.

BTW, I'm going with the BHW mani and the gtb1752vk on my mk3. The swap starts soon!

26psi tune until i get an 11mm pump and then 30psi. goal is 200whp but we'll see...

Well, think about it. You're building the motor to run 50-60% more torque on a low boost setting through a clutch/trans that was originally running only 123 lbs/ft. And this increase comes on, basically, off-idle instead of gradually/later in your rpm curve. I sincerely hope you upgrade your clutch at least.

Oh definitely, I'd be an idiot if I didn't.
