There is quite a bit of filter area on this filter.  I might set up my filter gauge on it and see if I am still pulling a vaccum on the suction side.  As far as I'm concerned that's the only way to tell.  I had plans to install a tdi factory airbox but I'm pretty happy with this.  If I am pulling a restriction then I will consider a larger cone style filter.

a TDI air box, or DIGIFANT air box would work just fine. assuming you make the bottom half flow as good as the top half..

Ahh, nice to have gtd up and running again!  I'm still trying to improve my vnt control and right now my current homemade wastegate is not cutting it.  It's too slow to react to pressure changes so I built another one using lda parts.


Hopefully this will work much better.  I should have it installed in a week or so.

Nice job on the swap and vnt control!
I'm just curious what machinery you have access to. Specifically machine tools.
Sure makes a more finished look when you can use a cnc mill for profiling flanges etc....

I actually made everything by hand.  The more complicated parts were done on a lathe.  I only recently gained access to a lathe.  I wish I had access to a cnc machine but the nearest one is probably in Edmonton which is four hours away.  And I can't afford to pay someone to do this stuff for me either.  A major goal of this whole project was to keep costs to a minimum.  But once it's all said and done I still spent about $7000 including the cost of buying the truck in the first place.

Oh, well my bad. Just assumed you had access to a cnc mill...
That's doin pretty good budget wise!
Youre gonna get us some more pics of the installed wastegate actuator right?

410 nice conversion! as far as TDI conversions it is one of the most practical IMO.

I'm floating right around 30mpg with city/highway combined.  I probably could get better mpg if I tried but I just love feeling the torque of this thing.  The way I have the pump set up the power just turns on like a switch at about 2000rpm.  I own a dodge truck with a cummins and a 2003 jetta wagon as well but neither beats the toyota on the fun factor. 

My next goal is building my own adapter plate.  I plan on spacing the motor ahead another inch and incorporating it into the adapter plate itself and also using a 1" spacer on the crank.  I have completed the crank spacer and sourced longer bolts, just need to finish the plate itself.

Is there any way you could post some more information on how you mounted your turbo?

Thanks

You bet.  I'm actually in the middle of preparing more upgrades to the truck.  I'm at my folks place right now but once I get home I have some new pics to post and info on what I have planned for this winter. 

To sum it up, I bought another turbo, a gt2256vk.  An exhaust manifold off of a b5.5 passat and 3" exhaust should compliment this turbo nicely.  I also purchased a methanol injection pump with nozzles just for fun! 8) 


So once I start the teardown it will give me a chance to take some pictures of the adapter plates I made to make the first turbo work.  I've learned to take more pictures while building these projects because once it is all together it's hard to explain what I had to do to make it work.  And everyone loves pictures of course.

Sounds like a plan. Thanks.

I am just trying to decide on a turbo as of right now. I want something vnt but I do not know a whole lot about them, so I am doing a little research to gather some information on them.

Did the gt1749va not work out so well for you?

And yes, pictures are worth a 1000 words.. lol  ;D

Hey Dan, Honestly I thought I was having problems with the gt1749va turbo.  It turned out to be a fuel supply issue.  But in the meantime I came accross this turbo from a mercedes sprinter for next to nothing so I couldn't turn it down.  The gt1749va is awesome and might end up putting it back on in the end, we'll see.

I see. Basically I am pretty sure my setup is going to be about the same as yours is. I have a ahu, landy m-tdi 11mm pump, fmic. I need to figure out my turbo and injector combo. I plan on running 2.5 inch straight exhaust, but maybe 3 inch.

I am still trying to figure out my vnt controller. I have tons of ideas, although I am thinking about writing a program to control it. Well I shouldn't say I am, but I know some people from my school that could wip up one pretty quick. But my fall back plan will be mechanical as yours is.

DIBS on the MERC turbo if you do go back to the 1749va... Yep I am a buzzard.

If I don't keep the Merc turbo I have a buddy locally that wants me to build him a complete setup.  He's got a 2000 golf tdi.  But I'll keep you in mind theman53.
