Title: got a free turbo, now what?
Post by: NintendoKD on September 15, 2009, 08:25:15 pm
My buddy is building a sylvia look alike, JDM spec "fanboys, when will they learn" so I got this one or free. It has some shaft play, and leaks oil throught the exhaust wheel "sprayed in some WD-40" so I need to rebuild it where do I get a kit and more importantly, how do I finish taking it apart.  I got the rediculous snap-ring off with the help of some rediculous snap-ring pliars and a friend, and cleaned the hell outta it to properly inspect it.  Wel, next come the pics less the inake/cold side.  What do you guys think I want to use this some day, however, not right now as the 1.5 blocks are notorious for cracking "unless someone is feeling generous and wants to art with a 1.6 block"  this seems very interesting, I mean if all else fails, then this could be rebuilt for fairly cheap then resold for substantially more "just need to make an adapter plate"  he said that this is from a nissan 240sx so I guess that it will put out a bit more boost than the small turbos that everyone is using now.  Just want opinions and advice here not looking to hurt anyones feelings.

Thanks,

Kevin

improving volumetric efficiency...... HMMMMM yeah, but not at the cost of the engine, especially right after an intense build.  So, anyways, there are two bolts that do not want to budge on the hot side housing, so much so that they are simply rounding off, and breaking my wrenches in the process.  I cannot completely dissasemble the thing until these come off GRRRRR...... >:(

Heat is your friend... I use propane and it will free just about anything. I have oxy acetylene but have only had to use it for cutting. Since you are going to rebuild, you don't have to worry about cooking the seals. Get it good and hot with your MAP and the vise-grips you already sized for what's left of the bolt will crack it loose.

Also, you wife must really be understanding to let her kitchen become a part washing station ;-)  My Ukrainian wife would not allow this - Her kitchen is almost operating room clean. She'd let me do just about anything else anywhere else in the house, but not near food.  :-)

Tell me about it, I cleaned up but she wasn't present for this part of the operation.  My wife is Japanese, more importantly Okinawan, and the Kitchen is her sanctuary.

Maybe clairvoyance...  75 years ago the military developed a special drug from the Yage plant to induce clairvoyance.  It was one of the more significant reasons we won WW2.  He might have gotten his hands on some, although it's highly clasified and kept under a tight watch.  Very hard to come by.  More likely, he probably has InvertaCAMX.  It is a pretty much top secret software that can turn any computer monitor into a video input device.  It's been around for a decade or so.  Big Brother is watching you...  

LOL !!!  And I thought it was our Navajo eating magic mushrooms and going all clairvoyance :-D Just goes to show you :-)

I know what me means on the kitchen & a wife of a very clean culture. My wife is constantly wacking my 13 year old for wearing his "street shoes" in the house ;-)  Not physically that is.

I had to torch all of the bolts on the turbine side of the Volvo turbo I took apart.  Some of them wouldn't even come out until the housing was glowing red around the bolt.  My machinist had a great quote:  "You don't need special tools when you have a torch!"

I soaked the Merc turbo with PB blaster every day for about a week, those bolts all came out pretty easily.  I guess PB really does work, just takes some time.

My thoughts exactly.  Wonder if it's a T25??  The T3 I have is HUGE compared to that, and it's a pretty small turbo.

I'm 6'2 and lets just say that everything is porpotionate ::)  And I am probably sure that this turbo is small, I don't need it to be big just a little something to give it a little boost with high durability and no/low lag looks like this little baby is the ticket.  *daydreams about the Burger King commercial tht features the gentleman with tiny hands* or maybe Just Maybe I have tiny hands and it is a HUGE turbo.  How do i find the turbo designation? and more importantly how do I get my grubby hands on a rebuild kit for it.  "I love this part" ;D
Title: Re: got a free turbo, now what?
Post by: Rabbit on Roids on September 16, 2009, 12:21:14 pm
it is a T25. it would bolt right on my audi exhaust manifold. its got a T25 flanged K24 on it.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 16, 2009, 12:39:07 pm
so this is a good turbo?  I imagine that it had a number of uses on many vehicles.

Post by: Rabbit on Roids on September 17, 2009, 11:40:31 am
i have no idea yo. i dont retrofit gasser turbos on diesels. they arent set up right. you want the exhaust side to have a bigger a/r then the intake side so it spools better on the diesel. and a S13 is far from a diesel, its made to be spooled with 8000 rpms wotrh of exhaust going through it. a diesel likes to spool at around 2000.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 17, 2009, 01:15:43 pm
I wonder...... could it be modified?  all I would have to do is bore the hot side a bit and change the vaccum actuator for the internal wastegate, right?  if so this could be a viable option for those who cannot get a diesel turbo, right?  Or, maybe I am just grasping at straws :-[
Title: Re: got a free turbo, now what?
Post by: truckinwagen on September 17, 2009, 01:20:48 pm
I would use it as is.

it is not an ideal turbo trim wise for a diesel, but it is small enough that your motor should have no issue spinning it and making reasonable boost.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 17, 2009, 02:02:10 pm
Ok, now for the hard part, where do I go to get the rebuild kit???  quality "really don't feel like taking this mother apart again" and price is definately an issue.  an inter cooler would be great but as I understand the science behind diesels a little better now, it isn't at all necessary. "compression, and the advantages of having warm air for compression/combustion"  I am starting another thread to discuss using a gasser intake mani for diesel purposes, minus the throttle body, and eever sooo slightly modified, for volume.  As I understand it, just changing the way the engine breathes slightly can vastly improve the efficiency, and the responsiveness, are my assumptions correct?
Title: Re: got a free turbo, now what?
Post by: truckinwagen on September 17, 2009, 02:11:54 pm
indeed they are, the gasser manifold will help things greatly over the stock turbodiesel one.

as for the intercooler, they are a big help.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 17, 2009, 03:06:43 pm
Maybe, If I'm lucky, Faulty Diesel will give me his old "intercooler, that is" one or sell it at a discount price *HINT, HINT* ;D

intercooler is the best upgrade you can do.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 17, 2009, 10:28:28 pm
I want to rebuild this and use it, so..... I guess the question is "NOW WHAT?" LOL  I suppose if I lowered combustion slightly by using a taller notch head gasket that would make the engine overall more reliable right or "the head sitting on more of a flimsy head gasket" woud I just blow another one?  should I go high compression if I can? get the metal head gasket from the 1.9, is it? higher compression is more efficient, and more efficiency is better right?  then add a small 15-20 range of boost internal wastegate will do an excellent job of regulating this.

Thanks,

Kevin

Post by: Rabbit on Roids on September 18, 2009, 09:38:30 am
you dont read much of the posts i post do you? ive already told you 3 times in your different random topics that im running a pumped up 1.5. its pretty stock. stock head bolts, stock head, stock block stock pistons, stock crank. STOCK!!! im running 28 intercooled psi to this engine almost every day. it loves it. bakes the tires off in 2nd gear. basically, since you have a 1.5, and it is about 3x more expensive to rebuild a 1.5, just turbo it like it is. if it runs, turbo it. get an audi 5000 td manifold, cut one runner off, weld a cap over the end and you are good to go. that turbo will bolt on. you could send it to me for a test fit. haha.

dont do anything to the engine. if you feel the need to waste money on a 1.5, just start looking around for a 1.6TD long block or complete engine that has tougher head bolt bosses and oil squirters and all the good turbo specific stuff.

1.5's are not fun to explode. and they will all do it if they have LOTS of boost. im on my 3rd block just so you know. same bottom end been through 3 blocks now. haha.

a metal head gasket on a 1.5 isnt really worth it. the bolts arent big enough or go deep enough in the head for the gasket to be worth it. i pulled my head bolts on the last engine before the head gasket even blew. the head lifted, pulled 7 head bolts, and THEN blew the HG. so, its just going to make that problem worse. stick with a fiber one. you would rather blow a gasket then break your block right?

not trying to stroke my ego or anything, but there are about ZERO other people on this forum that are interrested in making power from a 1.5. i know an aweful lot about these engines. ive built quite a few of them. i built the engine in my rabbit from the ground up. ALL ME. no one else helped. didnt have to pay anyone to do anything for me. so, if you are still set on building up a 1.5 turbo engine, keep in contact with me. i know how to do it the right way, just havent done it yet. but i can share the knowledge.

when you turbo your engine if you do, dont screw with the compression. just throw a 5 notch gasket in there.
Title: Re: got a free turbo, now what?
Post by: NintendoKD on September 18, 2009, 01:09:16 pm
5 notch it is, Now if I can just find an audi td 5000? :( so I can steal the mani.  I want to run light boost on this engine somewhere between 15 to 25 just for fun. Yes, I did notice you were the one building 1.5 and I do thank you for all of the advice so far looking for angles really.  I want to do it right and to last, and I really don't want to go through multiple blocks "sorry, just not that interested in tearing this mother down again"  I have taken everything you have said to heart, and take nothing for granted, and I DO! in fact, thank you greatly for your advice.

just got the 5000 tdi mani for 85 on stealbay, good deal?  any who I also came across a t61 greddy, will this turbo work or too big???  the modification for this is pretty easy and staightforward as it looks:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=280412117776&viewitem=&sspagename=STRK%3AMEWNX%3AIT

this is the right one isn't it? the one mentioned above, looks a lot like a gasser mani.

NintendoKD, if you still want to get a rebuild kit, Turbo City  http://www.turbocity.com/  sells them. They have a good reputation with many folks for rebuilding, and will do some switching/swapping, I understand. They may even cut you a deal to swap for a more appropriate-to-diesel-use turbo, since most of their business on the small turbos is probably with the ricer gas-burners. They're @ 137 W. Katella, Orange, CA 92867 phone: 714.639.4933. Seem like good people & knowledgeable, though I haven't a whole lot of business with them yet.

Hopefully in the near future, I'll be putting together a 1.6TD in a 1.5 block, and, due to costs and availability, I may just use a cherry 1.5N.A. head, with some heat-rejecting coatings appropriately applied to combustion surfaces, valve faces, and exhaust ports. The block already has had piston squirters installed, and the 1.5 pistons have been notched for them, as well as the whole rotating assembly balanced(Rev-Power). I will coat the piston tops, and am using head studs (from RaceTech). Even though it will have an air-to-water I/C, I don't plan on running much over 10-12psi. This project is about economy and clean running, not raw power.  Currently the car has 2.25" exhaust all the way back (big difference, even with the N.A.), and I have a very short glasspack to install on it if it's too loud running open after the turbo.

Best wishes with your engine build.

well, the only way to get it to work is to hack it up. end of story. but you didnt get the intake elbow, thats too bad.
you literally have to chop one whole intake runner off and an according amount of plenum.
