some helpful info greatly appreciated.
i need to learn how to identify a turbo (as i have a turbo on a manifold but have no clue what it is,) and i need to know what intake manifolds i should be lookin for.. i grew up Ford so i don't know which models will works for my goal here.
i search ebay but .. i just don't know what i'm looking for. can someone search ebay and show me things that will work, so i can see for myself? like i see this: * 99 VW Passat Upper intake Manifold 1.8L Turbo * on ebay but it doesn't appear that will work.
i know hans has the $450 kit but it includes the turbo, it's from prothe, and it's too expensive.
ROR told me on my WTB that i need the 2 manifolds, some oil lines, an oil pan, and the oil filter housing to make this work..
any input on any of this stuff would be greatly appreciated.
(want to take my NA, bolt on this turbo on a manifold i have, for cheap)

you need intake and exhaust manifolds, turbo, oil feed and drain lines, modify your oil pan for a drain, or get a TD oil pan, TD oil filter flange, or drill and tap yours for the proper fittings.
thats the bare minimum of parts you need to make this work. you have JUST A TURBO AND EXHAUST MANI, correct? is it for a VW diesel?
a 1.8 passat intake wont work.. its gotta be a TD 1.6 intake to work with the turbo and manifold, since the turbo is up high.
my turbo is mounted low, so i got away with using a gasser 1.8 intake manifold..

Looks to be a gt1749v. Should be from a tdi. Can probably be made to work.

congratulations, its a VNT15 from a TDI, same turbo im running..
also, you CAN run a gasser intake manifold with that without much modifications.. weld the EGR port shut, grind a bit on the tip ear of the port, and grind down a bracket on the bottom side of the intake..
you will need a TDI, and a TD oil feed line to build one that fits..
the front half of my feed line is TD, the back half is TDI.. i found a piece of brake tubing just slightly bigger than the feed lines, and soldered them together..
if you get that turbo setup correctly (take the VNT actuator off, and open the vanes all the way, or rig up a mechanical vane control) then your car will be a rocket just like my rabbit, and you too, will be able to enjoy 3rd gear burn outs.. lol..
this turbo is a GOOD ONE! consider yourself VERY LUCKY..
FWIW, this turbo does not fit on mk2/3 cars unless you build/buy a custom rear engine mount..

oh poopoo you say i need a new motor mount for this to work?
and this gasser intake .. does it need to be from a turbo gasser, or just any vw 4cyl gas motor? i mean i know where there's a 1988 gasser (at the junkyard now)
oil lines.. there are essentially no TD/TDi's at the junkyard right now. i'm ok using brake lines if you can??
use the cold start lever to replace the vacuum control do-dad?

I have a MK3 I'm about to install a VNT 15 into. I ended up buying a new motor mount; however after seeing this one if your at all okay with a bit of fabrication, it's not hard to make one. If I were to do this again I would fab my own. It's probably about $20 -$30 worth of material and a bit of shaping and welding. Look in the vendor section.

im going to be building some custom engine mounts soon.. the TD is coming out of the rabbit, headed for the jetta.. i need my torque back, or else to boost my gasser. it probably still wont be the same tho..

yes, you need a special rear motor mount to clear the turbo intake. the stock one gets in the way, BAD.
yes, a manifold off a normal 1988 gasser will be fine. it just has more ports to seal up, i used a intake off a 89-92 VW.
no, do not hook up the cold start lever to the vane control lever, where the vane actuator is now.. you really dont need the vanes to function corrrectly. the turbo will still boost up fine with the vanes open. the vane controller needs to be variable by boost and throttle position, and clearly, the cold start cable is neither of those. you basicaly get 2 options for the vanes in the turbo, open, inoperable, or completely operable as to how it should have been on a TDI, in terms of functionality, not how it was hooked up.
idk if i would use brake line as my whole feed line.. i used a 1" length just to make a joint to solder the 2 lines together.

I got your email.
I was thinkin I would operate the vanes myself, using the cold start handle to open and close them, and as my cold start has been rendered inoperable (it crept up as I drove, and then when I stopped @ a red light it would be partially engaged causing the idle to hang)

you would have your hand on the cold start lever the entire time you were driving the car..
the vanes are constantly changing positions based on engine load, boost, and rpm.. thats why they are computer controlled on a TDI..
the best ways to do it, is either leave them wide open, and un hooked, or hook them up with a mechanical actuator system so it works more closely to the way it would on a TDI..

Well this motor mount situation is proving to be to hardest part... This clown wanted $250 out the gate! He decided on $160 in the end.. I don't have funds like that to jus thro away. This installing a turbo thing doesn't need to cost $500 considering I already have the turb

If you want an easy swap..
Sell that turbo, and buy a complete TD car or TD motor with all the bits. Easy Peasy.
