haven't heard of those.......Ok, you have my interest now what are they? I thought with diesel engines, that because of the high compression you can't do smaller pistons and bigger rings.

smaller pistons and bigger rings? WTF are you talking about? you use the pistons that are in the engine right now. and you buy some total seal gapless rings. then you hone the bores and throw the new rings on the pistons. and then once you get it running, run it like ya stole it till the rings get good and seated. it will be appearent, it starts alot easier when the rings seat.

gapless, oh...... with gas engines you can have undersize pistons with oversize rings, a hone will change the bore won't it, which means that the pistons will be undersize, I have never heard of these type of rings are they cast iron, chromoly? curious. More importantly, where can I get said piston rings?

honing wont change the bore enough to worry about piston size.

a hone it is then, but the question remains, where do I get the said rings and what are the benefits of running them, also, any downfall? rings

You know, I really should start getting together a list of parts and their manufacturers as well as prices and where how I got everything.
I got the longblock mechanical turbo 1.6 from another member here, however others should keep their eyes on
www.craiglook.com,
www.ebay.com,
www.thesamba.com,
www.vwvortex.com, and any other vw forums such as
www.rabbitownersclub.com. look through the classifieds you may just get lucky. I got an g-60 intake from ebay, as well as a audi 5000s turbo intake for a pretty good price.

I really need to start doing some research on a turbo, that way I can order/make my intake/exhaust mani's and the turbo itself. It's a buyer's market out there and I have found quite the treasure out and about for very little money. For what I'm doing, "25-35 psi boost" what is the best vgt/vnt setup? I would really like one of these type turbos for ease of use and low lag properties. However, I have been talked out of so many other things concerning this build, I could be wrong here too.
thanks,
Kevin

bmw 520 turbo? too big? I want my power close to the bottom end. I know that's what I want, as for the injection I have been told to find an ecodiesel pump and attatch the turbo 1.6 "UFO" to the top for the best of both worlds to prevent smoking, adding too much fuel, and subsequently, melting of the internals
go? no go? also, anyone know the P/N's for these pumps? I am looking for a no crap way to determine which pumps are the eco diesel ones while searching.
Thanks,
Kevin

I might not know much but I would think that a pump built by giles would be your best bet. From what I have read which is no where near enough, that you tell him what your doing and he will build you a pump that will perform like no other.
Also from some of my conversations with my friend who races/builds Porsche's that boost is not the all mighty answer to power. Sure 35lbs of boost might sound great but with out the right fueling, boost will provide nothing but excess heat. Say 20-25lbs of boost + the right fueling will yield more performance and create less drive pressure and less heat. This is a hypothetical situation. All I am trying to say is that, figure out the pump/fueling and don't worry about the numbers that you will be "boosting."
Like I said, I will be the first to admit that I claim to know nothing. I am just starting out and I want to learn also. If I am wrong on this let me know.

that is my plan
I am trying to get my ducks in a row before I start doing anything crazy. I want one of these ecoTD pupms for the build or any 1.6 turbo pump for that matter to send to giles for the build. I need one to send to him though so the search still continues. I do need to go ahead and get the turbo though, I need to plan out my intake intercooler and exhaust mani's as well as any pipe work to be done.
thanks for the advice though,
Kevin

Got a 1.6 turbo pump today from ebay, now I need a rebuild kit and some info on how to tune this monster. Giles will have to come later, when I have more money. thanks for all of the help guys.
thanks again, and happy holidays,
Kevin

if you want low end power, kiss a big turbo goodbye.
a K03 or K14 are good low end turbos, but they dont make no 25-35 psi boost. basically you get one or the other, not both. you can either have no low end, and loads of boost once the huge turbo spools, or <--- Large turbo
you can have lots of low end with no top end above about 4500 or so. <--- Small turbo
or, you can run a set of compound turbos and have low end boost from the small turbo, then once the big one lights off, hang on.

that's going to be the plan, I have already started reading about some of the guys on here doing just that. Compound turbo setup for this guy, still think that dry sump is a foolish idea?
This, ladies and gentlemen, is going to be NUTS.
thanks,
Kevin

ok, even with compounds, the downfall was, that none of the guys running them could keep them running long enough with compounds. they would alwasy ALWAYSblow head gaskets, or crack heads, or bend rods. the heads on vws actually flex and bend from the extreme cylinder pressures. ask andy2 about compounds. unless you want 50 or more psi boost (witch is kinda useless in a vw, cause you are gonna blow a HG or bend a head every time you boost it) you should just go with a nice sized single turbo. a K26 easily pushes 35 psi boost on a 1.6 VW. i was stuck on compounds for a long time too, but its kinda pointless and there flat just isnt enough room. i vote for a larger single turbo and a shot of nos to lite it. NOBODY ON HERE really has a build up with a nitrous setup if i remember right.
