I know, k24 are old, less efficient than newer turbos, but still work good and are very very cheap!

I pulled the engine with out much fuss and separated the transmission.  Unfortunately when I was removing the flywheel I stripped one of the bolt heads.  I have never done that before.  Now I get the pleasure of trying to drill the head off of the hardened steel bolt.  My drill bits are not really up to the task but I don't know of any special tricks so I guess I get to slowly wear away at the bolt and will hopefully be done sometime this weekend ::)

Also I still haven't heard from anyone i emailed or pm'ed about turbos.

Matt.

I forgot to say WOW...I got my first look at the stock turbo and was surprised at how small they are.  I don't know what I expected but it looks like a toy.

As far as a new turbo What about something like this. 

http://www.ebay.com/itm/TWISTED-MOTION-GT3582-QUICK-SPOOL-TURBO-AR-63-HOUSING-K-SERIES-K20-K24-V2-/331915698866?hash=item4d47b7a2b2:g:YioAAOSw~gRVzQ0Q&vxp=mtr

It has a t3 flange which is quite common I think so I will have a reasonable amount of choice if I want to change.

Any time I strip the head of bolt I resort to getting into the 1/4 inch sharp steel chisel.  You get one good tap on one of the six corners and try to drive the bolt loose with a sharp rap.  Kind of like you are turning it with the chisel.  On the tanget to the curve of the bolt. 

Sometimes I get a deeper groove in the bolt first by hammering directly perpendicular to the head of the bolt.  Chisel pointing at the bolt center.  Once I get a notch made I turn the chisel 90 degrees set it in the notch and give a sharp rap with the hammer.

Seems to work most times.

Unfortunately these are recessed Torx head bolts.  I will look to see if I can get a chisel in there but I am not hopeful.  I think I will have to end up drilling it out and I don't think it will be too bad.  I do have a die grinder but I don't know if it is worth trying.

Matt.

Any one you know have a set of reverse ground drills?  Once you get some of the head off they come out at times like when you use an easy out.

I haven't had much time to mess with the stripped bolt but I will get it...I always do. 

I haven't had much luck over at TDIClub either.  People there seem to feel safe telling you what not to do or what you are doing wrong but no one wants to tell you what to do or what might work.  Probably because they don't want to be told what they said wrong. 

What I have found that I think will work is r520 7hole nozzles and a k20/24 hybrid turbo.  I have looked and emailed and pm'ed searching for more turbo info but either no one knows or they are all keeping any information secret.

I don't know how much power it will make but it seems big enough to make more than stock power with out smoking and should be able to keep the egt's down.  Does anyone have any idea what I could expect with this setup?

Thanks, Matt.

ps...feel free to tell me what I am missing or what is wrong with my idea.  That is why I am here...but also throw out an alternate idea if you have one.

Hi, k24 turbo is what I told you before. I advise you not to go for hybrid versio, even if you'll use it in a boat with constant rpm. K24 is able to hold 25 to 30psi in Peak, and that will produce about 200hp.
As said, k24 is an old turbo, not as efficient than newer, but it's a cheap big turbo, depend of how much money you want to spend.
I love my k24 for its reliability and power it produce, but later I wanna go for a faster spooling one and why not turbo compound.

I see "GT3582" in that eBay URL above. For reference most folks who are making 200ish HP on TDIs are using something more like a GTB1756. The first two digits (35mm or 17mm) are the size of the turbine. The second two numbers (82mm or 56mm) are the size of the turbine. If that hybrid turbo is anywhere close to a 3582 then it is way, way, way, waaaaayyyyyyy too big for a VW diesel, probably even too big for a V6 TDI.

A regular K24 off of a 1.6TD would work pretty well; as mentioned it isn't the most efficient thing in the world but they're readily available and cheap. The K24 "frame" like most turbos comes in quite a few different combinations; if it isn't a VW TD K24 then it probably won't work well on a VW diesel. In other words not all "K24" turbos are the same.

Sorry for the long delay.  I have been working on the hull and not even looking at the engine.  I will upload some pictures so you can see what I have been doing and to show that I have not dropped the project.  I am hoping to be working on the engine in the next couple of months.  I do need to start buying parts like a turbo and some bigger injectors so if anyone has any used pieces that they want to get rid of let me know as I am on a budget (of course)

I am finally getting back to the engine. I am going to change the timing belt with a kerma 100k belt kit. Do I need the timing belt tools they sell?  Do I need anything else like the cam lock plate?

Also, I still haven't been able to get in contact with Alcaid. He emailed me once but hasn't responded again. Who else should I got to for a turbo or which eBay turbo would work.

Thanks, Matt

Hi Matt!

Nice job with the hull!
Better wait for Alcaid answer, normally he is fast if you seem to be a good buyer!
