He's having enough trouble with one turbo.

Re: Swifty's never-ending project thread!
 

Part it out.

Either that or buy a http://cgi.ebay.com/ebaymotors/WOW-O...item41512577b6

Yup.

Obviously not a drag vehicle but I'd love to have one for road course. Amazing cars for the price.

Re: Swifty's never-ending project thread!
 

I want SO bad. I love these cars.

fuck yellow though, there's a dark cherry one in MN I want real bad.

Re: Swifty's never-ending project thread!
 

My guess would be more of an oiling issue. Feeding or draining.. Either way, if you dont part it out I give you a lot of credit for sticking with the car for this long. I almost gave up on my car after only 2 months of BS.

Re: Swifty's never-ending project thread!
 

No its becuase they kept using a 270 degree thrust bearing system in the turbo instead of the 360 it needs to support the thrust loads.

With the 270 degree system there isnt enough oil in between the thrust bearing to support such a big compressor wheels thrust, and pretty much just pushes out the oil out of the way. Especially when closing the throttle after high boost. If you can hear your blow off valve flutter after you relased the throttle under high boost, it is removing and applying thust load on that thrust bearing mulitple times, and killing it.

"After overlaying John's graph with mine, the stupid ar housing doesn't help spool at all, and the gt42 t5 turbine wheels are pretty efficient enough. I'm actually aborting the turbo all together..I found a REAL gt4294 for CHEAP..just comes with a t6 internally gated housing I need to remove and swap out."

Re: Swifty's never-ending project thread!
 

why not just have someone build you another new exhaust manifold. hahah, then switch the head.. then go with higher compression piston... then (you get the idea hehe). Just givin ya shit swift, good luck with the new turbo

Re: Swifty's never-ending project thread!
 

I just don't get it.

Re: Swifty's never-ending project thread!
 

I've said it before, quit buying junk turbos. You end up spending more in the end.

Re: Swifty's never-ending project thread!
 

It's prolly REAL cheap for a reason, unless you found a diamond in the rough.

Re: Swifty's never-ending project thread!
 

6765 and be done with it dammit!

Re: Swifty's never-ending project thread!
 

^This.

Re: Swifty's never-ending project thread!
 

Updating, since scheides twisted my arm over it.

I've sold my guitar setup, since it was a liquid asset that i didn't mind parting with, to fix this fucking car for the end of year.

Found a new gt42 for sale. Guy was asking $200. I went and looked at it, and talked him down to $100 (he's a vw guy). it came off a detroit diesel series 60, and came with a t6 1.28 internally gated exhaust housing. I took that housing off, and am looking for places to list it for sale on, as I will never use this. The rest of the turbo I inspected, looks GREAT. It was dirty as hell from all the diesel oil and such, so I tried some easy off oven cleaner, and got most of it clean. Still wasn't up to my par, so I ran up to Primo, and with their help, soda blasted and cleaned off all the parts, wheels, housings, and such really well. I have the new torque specs for everything, after conversating with Nick over at Diesel Components, and will be reassembling the turbo in no time. the nice thing about it is the parts all look new on the inside. It has a 270 deg. thrust bearing, but most of these turbos from the factory come with it. What I really liked is the fact that it was stainless steel, NOT brass like the last turbo I had. This shows no sign of going out anytime soon.

I found a housing from a supra guy, and after he shipped it to me, it was the wrong one. He said it's for a gt42, but once I got it, looked at the casting, and mic'd it all, it will never fit. I believe it to be a housing for a GTS turbine wheel, like the 74 GTS turbos those supra owners all love. All is good, he's refunding the money, and i'll ship back the housing to him. Still looking for a gt42 vband 1.01 housing, so we shall see what comes of it.

Hot parts are all at Primo getting their treatment/coating, and the valve cover too, since the corner of it got fucked up somehow. New color, after looking over my options will still be black, but with a "fire sparkle" top coat..basically a little red glitter. Not overly excessive though, but just a hint of it. We shall see how it all turns out. Once I find the housing though, and get everything back, car will be together, running, and doing pulls within an hour. So, I'm just playing the waiting game.

/end update.

Re: Swifty's never-ending project thread!
 

I'm waiting on reply from the guy I found.

Re: Swifty's never-ending project thread!
 

Thanks buddy. I have a pic somewhere I sent to mike and them of both turbos sitting next to each other on my toolbox, but I can't find it on my phone..I prolly deleted it already.

Re: Swifty's never-ending project thread!
 

Sounds good swifty! I hope everything comes together soon!

Re: Swifty's never-ending project thread!
 

Just do two sc61's in parallel. I will sell you the first one today. :) Good luck on the truck turbo.

Re: Swifty's never-ending project thread!
 

Try posting that 1.28 housing on here, someone might be interested:

I had it saved so I could zoom in a little better on the small screen on my phone.

Re: Swifty's never-ending project thread!
 

Nice to see that you're getting it back on the road soon! When do I get a ride?? ;)

Re: Swifty's never-ending project thread!
 

Hopefully This time around the used turbo won't be a pile of junk...

Re: Swifty's never-ending project thread!
 

I really hope it works for you man, but man just seems like another risky deal to me. Why not just cut your losses, and pick up a new turbo, something that's known and proven to work, from a reputable vendor, and be DONE with it!

Re: Swifty's never-ending project thread!
 

Oddly enough, it's been the used turbos that have worked for me. the only new one i've ever owned, I had issues with.

Many will poke at the fact it's a used turbo, but I took it apart, and have looked over it. I personally am building it too, not some po-dunk fucktards in FL talking shit over the phone and calling me "bro" in their mexi-accents. I cannot afford a brand new turbo. I also wanted to not really modify AGAIN the rest of my setup to work with another new turbo. This will bolt right in place, and the price gave me the oppertunity to get the car running again, with hopes of traveling to the strip before year's end. If they work for over 300k on a semi, why not for me?

Re: Swifty's never-ending project thread!
 

I just worry about that 270* thrust bearing...

Do you have much experience building turbos?

Re: Swifty's never-ending project thread!
 

I've taken apart and built old ones I had. It's not difficult. Chad, who works at a diesel shop also went over things with me, and I got all the torque specs for it.

I've spoken to diesel components, FP, garrett and pte, they all say turbos of this size come factory with that 270 thrust bearing. It worried me too, trust me. And, odds are I will be ordering an upgrade kit for it over winter, or sending the turbo into PTE to get their billet upgrade, but we will see. I DO like the fact that it's SS and NOT brass/bronze..whatever it is. Either way, we shall see I guess. Just another part.

Re: Swifty's never-ending project thread!
 

I dont see how that matters as everything is riding on a hydrodynamic oil wedge, not the actual bearing.

Re: Swifty's never-ending project thread!
 

Interesting fact I just found out. Borg Warner / Airwerks turbos typically come with 270 thrust bearings. I'm guessing my S362 has a 270, and so far so good...

Re: Swifty's never-ending project thread!
 

Swiftys new turbo is a diamond in the muff.

Re: Swifty's never-ending project thread!
 

Joe is right. It does ride on oil, but after discussing things with Chad, This theory was formed:

the comp wheel was a BAD pairing for the turbine wheel. Imagine trying to play tug-o-war..with a 2 year old..they are the turbine wheel, and you are the comp wheel. Anytime i'd hit boost, the comp wheel would "suck" itself towards the comp cover, forcing the oil out of the thrust bearing area, and the thrust collar would then ride/wear against the soft brass metal the 270 bearing was made out of. When letting off the throttle, the shaft assembly would "shutter" back n forth, causing more wear. I have the old thust bearing/collar that shows a bit this to be true. So, I think the new setup will hold together just fine. Hopefully, no other issues with anything else on the car.

Re: Swifty's never-ending project thread!
 

Joe is correct, it really shouldnt matter what it is made out of as if it is making contact, its done for eventually. The oiling system of the 270 isnt allowing enough oil in the contact area and the thrust of the compressor wheel is splashing it out.

As far as differant turbos having 270s having no problems is probably the fact that they dont use garrett center sections that have a weak oiling system on there thrust plates.

Re: Swifty's never-ending project thread!
 

Well, now I am stuck trying to find a damn housing.

Re: Swifty's never-ending project thread!
 

.98 housing is ordered. And, I went to target to get a fire extinguisher for the car too. After an old friend's teggy burnt to the ground in delano, to John's fire scare, to Aaron's old scare, I realized..I don't wanna be caught out, and not prepared. It might be rice, but I'd rather be safe, then sorry, and watch such an investment burn to the ground. Target sells Auto specific extinguishers for around $15 bucks, and I suggest anyone get's one. I dont ever plan on using it, but JUST IN CASE..I'll be prepared. Now, I just need to find were to mount it.

Oh, I also got some r134a in a can for the winter beater, since the windows don't work, and I have no A/C in it..hotboxing this summer has sucked, and I couldn't take it anymore.

Re: Swifty's never-ending project thread!
 

I feel ya. My beater doesn't haven't air. I think I'll daily the Evo until the weather turns.

Re: Swifty's never-ending project thread!
 

Frankly, I don't know why cars don't come with a small fire extinguisher from the factory. Who knows how many roadside carbeques could have been extinguished before the car was fully engulfed by a little extinguisher. It's not rice, it's called safety.

Re: Swifty's never-ending project thread!
 

I agree. I saw first hand the aftermath of some kid's teggy, when I first got the talon, and was putting it together at his shop. Now, after all the other frequent small fires, I said $15 dollar insurance policy is nothing when it comes to the investment.

I'm trying to decide were to mount it. Either in front of the driver's seat, or passenger seat, out of the way of the legs. I dunno were else to really mount it..not many locations I could.

Re: Swifty's never-ending project thread!
 

You could always do something on the lower side of the cage too. Seems like a decent out of the way yet accessible option. (via back seat area)

Re: Swifty's never-ending project thread!
 

I vote for the dash board as a mounting spot :D

Re: Swifty's never-ending project thread!
 

IMO, you ideally want it within reach of a window, or even the driver seat. Just solidly mount it somewhere where your body can't hit it in case of a wreck. In our Chump car we welded the bracket to the cage by where the glove box would be.

Re: Swifty's never-ending project thread!
 

I thought of that too, but can't because the MSD is mounted there.

Re: Swifty's never-ending project thread!
 

I just did a quick google search and it looked like quite a few people were mounting them kind of under/in front of the passenger seat like this:
http://www.sandsmuseum.com/cars/elis...tinguisher.jpg

If you think about it, yo would be able to reach it from the driver's seat, or from outside the car that way.
