I'm willing to bet its more than a little. My buddy just dyno'd his bnr stage one (vtrim comp wheel in a stock housing) and he made 290 whp @ 13 psi.

I'd like to go with an H-trim wheel myself, but 60-1 is so much easier to get a hold of, I may be doing that instead. Is your turbine wheel clipped?

remember to tighten the nut with another 1/4 turn with locktite.
I forgotten to give it an extra 1/4 turn and the nut came off (with locktite) and really fucked up my 60-1 wheel : /

I got a knightsport with a vtrim and a stock compressor housing with a to4e 54 trim wheel. both with stock unclipped hotside. I really want to see how much power these turbos make, but car is going to be down while I ready the new engine.

When I torqued mine, I got it finger tight, then rotated the extra 90 degrees (+ red loctite). Getting all 3 pieces to line back up perfectly is a pain, and it took a few tries. And the only reason I had to take it all back apart (I had Gpopshop torque it the first time) was the incompatibility issue I ran into with S4/S5 heatshields and turbine housings. Apparently early-S4 turbos used 2 heatshields, which requires a deeper recess in the housing.

I added the heatshield info as well as more pictures and info on how I had to modify the wastegate actuator & oil drain line.

Okay so I'm leaning toward doing a 60-1 wheel but I'm having trouble finding a compressor housing. Any reputable websites you guys would recommend?

give these guys a call, they are good source for individual turbo parts. not all 60-1 are the same, make sure you get the hifi version

Hello, does this look like a good donor?
There's no specs listed and I'm not having any luck with google magic:

Without specs, no one can say for sure. I'd ask for wheel measurements. It's only 6 bolts holding the housing on. The compressor outlet also looks pretty big, and would be unlikely to work with the stock couplers if you're keeping the TMIC.

Guys, I'm having a really tough time over here, sourcing parts. I'm trying to do a 60-1, but no one ships to APOs (military overseas) and if they do they want more than the parts are worth to do it. If anyone can help me out, I'd really appreciate it.

^^ I say get it shipped home in the states and have someone ship it to you to the base. That's what I had to do when I was in the Navy.

The problem with that (and why I can't use APObox.com) is nearly all of the affordable eBay sellers require shipping to a confirmed address and I don't have a confirmed stateside address.

Didn't the 60-1 come on a lot of Volvo diesel applications? I'd imagine they should be even esier to come by on the other side of the pond.

I wasn't aware of that little tidbit...there happens to be a volvo turbo diesel in the junkyard on base right now (I think). I may have to swing by tomorrow during lunch. Thanks!

Some info that may be useful with more searching:

T04B part numbers: TO4B - Garrett - Catalog - TurboMaster

T04S part numbers: TO4S - Garrett - Catalog - TurboMaster

You can see that many of the turbo models were used in OEM European applications. I attempted to find you a T04B 60-1 compressor part number/application, but couldn't find anywhere that gave the PN and wheel specs. I think the T04S turbos all had 60-1 compressors, but I'm not sure why there are so many PNs listed on that page.

I finally found a 60-1 compressor side kit for a Cosworth RS, from a supplier in the UK. They're legit Garret parts, but unfortunately, because of the exchange rate, I'm gonna take it in the *** on price. All well, I'll just be glad to get the turbo built and get on my way to finishing my build.

Ok, so I'm finally getting around to tearing down one of my donor turbos (I have 4) and I found this on one:




Should I be concerned? It appears to have occurred as a result of carbon building up between the heat shields and the "swelling" caused the shield to contact the turbine wheel. Everything is being balanced anyway, I just don't know if it's too much damage to be usable or not. Input?

Also, the 60-1 housing I got looks like it takes a different type of carbon seal...the factory one doesn't fit. If I just get the seal that fits (probably dynamic), is that the end of it or will it not seal to the factory CHRA?

^More likely the bearing failed allowing the wheel to contact the heat shield. I'd throw away that heat shield as it's just a liability to put more metal shards into the exhaust turbine. As long as the fins on the wheel didn't get chewed up by debris, it should be alright. The bearing surfaces look unaffected. If you do have 4 cores to work with, you will probably find a better one to use, though.

blk87Turbo2

I'm nearly positive it wasn't a bearing failure as there was no thrust play at all. It was actually very resistant to turning because of all the carbon build up in the turbine heat shields. I'm going to pull apart some other donors and will just keep this one as a reason for why you should address a severely smoking turbo sooner rather than later. My thought is that it was blowing so much oil past the seals that the oil and carbon in the exhaust created a pretty solid buildup that was allowed to put the parts into each other because of thermal expansion. You should have seen the area between the two shields...it was solid crap.

When I took apart the stock turbo that was in my car (it had been smoking intermittently) there was considerable carbon buildup around/on the heatshield and on the rear piston ring. The oil had burned off and left a purple/black/brown color. I could completely see how enough buildup could push the heatshield towards the turbine wheel. I don't think I would use that shaft/wheel or the heatshield. Yours has way more buildup than mine did, so it must have been pouring smoke out the tailpipe.

You just need a rebuild kit with the dynamic seal (piston ring) and the matching thrust collar. You can verify from the pictures I have at the beginning of the thread. My turbo has a dynamic seal.

I had actually managed to get 4 S4 turbos for $50/ea a while back and this was one of those. Today I took another one apart and it was in much better shape. It had more axial and thrust play, but with all new bearings I should be good. I'm also working with the balancing shop to supply just the dynamic seal and thrust collar for when they balance everything.

Just bought the kit with the 360 thrust bearing. Instead of going with some eBay turbo kit.

I am considering a S5 turbo with a T04B cover and U trim wheel TA34 turbine whicj I have on hand and ported wastegate but the problem I am facing is that i want to use a set of 9.4:1 S4 NA rotrors, and the thing thats scaring me is the internal wastegate even tough ported will it cope with the higher compression rotors ? the TA34 does reduce back pressure and is a bit lighter, but the internal wastegate / actuator ?
What should I watch out for in order to use the 9.4 rotors and a High flow S5 turbo ?

If you properly port the wastegate, you will have no issue, even with the high compression rotors and TA34 turbine shaft.

Just watch for boost creep. But just port the wastegate much as you can and should be fine. Im using 9:4:1 rotors and turbo and doing just fine
