Tunes & Tasty Fumes

[Diesel.dave.with.a.goal]

Hi everyone I'm new to the TDI club, I've got a 2001 Jetta ALH 4 speed auto
I'm planning on doing a 6 speed manuel swap sometime soon, but I've been thinking about trying a bigger turbo than say a Vnt 17 or anything to that nature. I'm planning to make a custom exhaust manifold to a T3 turbo flange and a T04E style turbo . would i be able to spool up a turbo of this size with a stock 1.9 and my aim is 30psi of boost

 

[Diesel.dave.with.a.goal]

I meant to say could I spool it up sort of fast like stock(within reason being its a big turbo in comparison to stock)

no
just shift at 6k, then it doesn't matter that it doesn't do much below 3500

 

[Diesel.dave.with.a.goal]

Can a ALH actually get to 6k without blowing up

 

[Diesel.dave.with.a.goal]

I'm trying to actually learn stuff so if I ask dumb questions please give your best answer or help me with the right terminology I'm very new to TDIs in general.....so when you say 6k I really have no idea whats safe

The turbo you suggested is really a poor choice. You want a variable nozzle turbo, not wastegated. The VNT17 is a variable nozzle turbo. Past that you either have to go with a hybrid like a VNT17/26. Problem is the integrated exhaust manifold. If you really have deep pockets then you can go the GTB turbo route which is the later style VNT. Better spool and more efficient, however you will need to get a tubular manifold or figure out something else.

To be honest I hope you have quite the motor built because anything past a VNT17 is really pushing it on a stock motor. Rods and headgasket are going to be first.

 

[Diesel.dave.with.a.goal]

I appreciate the reply very much, I'll take this thread down and reconsider stuff. I'm looking into doing a custom remap and if there's any advice on that I would appreciate it!

it's all good man, we're all always learning

to expand it out, when I hear t04e I think of the guy that's on my DT360, an old dinosaur with an MDT-spec turbine housing that is far and away too large even for the 5.9 liter engine that that thing is
you would do slightly better with an 80 dollar t3/t4 off ebay, but it'll be chinese trash with a... proven to be substandard thrust bearing

they'll spin to 7k on the stock rod bolts, most don't though because of how small most guys size their turbos, combined with how little fuel flow you can get through even very large nozzles at that kind of pump speed
know how the stock engine falls flat on its face over 3k? most of that is the turbine being a massive restriction

What about an GTD1752 or GTD1756. The 1752 is at its end with 30psi, the 1756 can take a bit more and they both spool very well. But what else do you want to upgrade, that you need so much boost?

Yeah I knew the turbo on that engine makes it lose steam really fast after 3k, but i could probably go with a smaller housing turbo. I just like the idea of making a manifold and having more spool noise

Well as I said to [486] I really just want to fabricate a manifold up and hear a bunch of spool noise. I purchased my Jetta for only $500 cad so its not like I'm worried about it being super great or anything......I own a golf bew thats already manuel and I love that thing to death.....that being said I want to play with the alh and do so without a in manifold turbo as I really don't like the idea of them being so small and unconventional

 

[wauwau]

Is a GTD2263VZ big enough?

 

[Diesel.dave.with.a.goal]

yeah that would be about right....what about one of these 2 choices https://www.ebay.ca/itm/32535718186...=2047675&ssuid=&widget_ver=artemis&media=COPY

Lol, ask [486] he would know for sure. I'm pretty sure he has or at least had one of those saab tubros bolted to an alh (9-3 I think?). If you look around you may even be able to find the thread too.

Those are waste gate turbos, but with a little modification and some spring swapping for the WG you'll get it to work.

 

[GlowBugTDI]

To be honest tho the vnt 15 is a great turbo and they make spool noises all day long.
Vnt17 or hybrid like others are saying is a lot more of a plug and play setup. Tho if you want to make a manifold you could technically cut it apart and weld your own.

 

[Diesel.dave.with.a.goal]

Yeah well ill see then....its got a stock cat and all that stuff except emissions crap, I deleted that

 

[Diesel.dave.with.a.goal]

Is the egr cooler worth anything like a cats worth ?

 

[Diesel.dave.with.a.goal]

And when I say custom manifold I mean the whole thing.....I'll save my vnt15 for my bew since the kp39 kinda sucks

 

[GlowBugTDI]

Do full straight pipe that'll help make noise. You won't hear anything with a cat in the way. Even then there is a chance it won't do the "phew" sound. Mine didn't for about another 10k

For the egr cooler not really, i mean on ebay you might sell it or on here every now and then someone needs one. The cat is your "big ticket item" (~100$) kinda depends where you live. Just an fyi the inlet to the cat is 2" the outlet is 2 1/4" but you can weld so probably not a problem.

 

[Diesel.dave.with.a.goal]

yeah thanks a ton....... so i could leave this thread up and post my overall progress on my cars?

 

[GlowBugTDI]

That or you can make a new one about your build and everything you do with them.

you could put it under the VE mk4 section...

I have one there that has been needing an update for a few months now lol

 

[GlowBugTDI]

I don't know if you know this, but a vnt turbo sounds differently then a waste gate turbo. Just thought id throw that out there....

 

[Diesel.dave.with.a.goal]

Yeah I know...I've been trying to get that sound put of a kp39 on the bew and I have heard that there not able to make such a noise

 

[GlowBugTDI]

Ya people say that about the vnt15 too. Honestly i can't figure out how that works.
I had 2 beetles exactly the same. One made the noise the other didn't. About 12k miles later the other one started making the noise and now is as noisy as the last one. No shaft play, didn't change anything, and i still have no clue.

I am running gtb2260/Exhaust Tube mainfold/3 inch downpipe/bosi 764 injectors/Tyrol Sport intercooler. on my 2001 Alh Beetle with a malone Stage 5 tune. Stock motor, Stock Trans. Got about 4,000 miles on it. I don't hit full spool till about 2800 - 3000 Rpms. Pushing around 31-32 psi. *Studded*

 

[Diesel.dave.with.a.goal]

Right on dude, so what RPMs are you shifting at ?

Got any dyno numbers?

0-60 times and pictures are always nice to see, have a thread anywhere? Tho they are heavy as crap I like the beetles

 

[burpod]

nearly 3000rpm to make 30psi doesn't seem terribly fun. sounds like it's probably a struggle to do much under 2500rpm :/

 

[GlowBugTDI]

The way I drive....probably wouldn't be lol. I need fast boost so that I can pass cars, and weave with ease lol. Small sprinty cars is where its at for me. Plus i tow.

 

[burpod]

i don't think things must be right with these 2260 tunes i see... if it's taking that much fuel and rpm to make 30psi and doesn't do it until 2800+rpm, i can only imagine how inefficiently it must be running at the lower rpm, which takes away a huge chunk of the rpm range where a tdi should be shining...
