That's the wastegate actuator.

Yes I know but I was showing that these were the only other markings on it.

Took some pics of my turbo when I had it off to replace all the gaskets. Was told it was a Borg Warner 60trim and got no more info on it. Zero shaft play and it does pull hard. Just wish I knew for sure. Any info would be appreciated.

Thanks
No markings or tag on it where the name plate would be.

Need pictures of the actual turbo compressor and turbine housings and everything, pic of the wheel and overall doesn't help much. I doubt it could be a "60 trim" being it looks very small but the whole "trim" sizing is retarded.

Yeah I agree the trim sizing not being good. That's just what I was told. Pics don't do it justice. It's actually pretty beefy.

The turbine housing is a bolt on .55 AR by bullseye power thats all i can tell with the given pictures

Bullseye T04B 60-1.

Ok thanks. Is it an ok turbo? Car pulls hard and all. But I'm only running rc650 injectors with an aem ems series one right now. The tune I'm running has them at a 60% duty cycle at about 14 psi with 11.2 afr at wot. Looks like I still have a lot of work to do. Car was a mess when I first got it. Hopefully I'm on the right track. My numbers seem off tho.

Garrett T04B-something....pretty sure the old V-Trim was the compressor with an inducer of 54.2. Probably has a giant P-trim turbine and has no business being on a performance 4-cylinder....do some research regarding how the T04B V-trims worked on DSM's before deciding to run one.

Thanks for the reply and sorry for the late response. I found out that the turbo I have is actually a U-Trim. I can't find much information on it except for a few posts over on a RX7 forum and a post on a Mustang SHO forum. The U-Trim is a 60 trim T04B while a V-Trim is a 63 trim. Unfortunately, I couldn't find any compressor maps or flow data. The strange thing about the turbo is that is has a bolt-on exhaust housing similar to ones Bullseye Power sold in the past. I'm wondering if this is one of the bolt-on offerings that Bullseye sold in the past for our cars. I guess I'll take my chances and try it out.

Eh, there are definitely better units out there with newer tech. If it doesn't spool to late and seems to work well otherwise, then I'd just keep it there.

Not sure what data you're researching, but a compressor with a 54.2mm inducer and 70mm exducer absolutely has a trim number of 60 as you've stated earlier....and a 54.2/70mm compressor is absolutely a T04B V-Trim wheel.

It would be a Bullseye Power T04B V-Trim...plenty were sold, none worked out very well. Long story short- the turbine flow is too great for the compressor- so it's laggy, very prone to surge if the boost level is high enough, and doesn't flow anywhere near what the compressor is rated for as a result. An Evo III 16G will outspool and outflow a V-Trim on a DSM.

I think Justin was referring to an earlier post(DSMlover's), not yours. @Rocuskie

I'm not trying to start anything since you have a great reputation when it comes to turbocharger knowledge and I really do appreciate the help. However, I believe you are incorrect about my turbo. It is indeed a U-trim compressor wheel. Here is the info I found on an RX7 forum pertaining to T04B compressor wheels:

8 Blade T04B:
409179-0021, 70x48.36 mm, 48 trim, S trim (37 lbs/min)
409179-0022, 70x49.50 mm, 50 trim
409179-0023, 70x51.61 mm, 54 trim
409179-0024, 70x54.00 mm, 60 trim, U trim
409179-0025, 70x55.37 mm, 63 trim, V trim (48 lbs/min)
6 blade T04B
409826-0006, 70x48.35 mm, 48 trim
409826-0012, 70x52.85 mm, 57 trim
409826-0014, 70x55.30 mm, 62 trim, V trim (48 lbs/min)
409826-0015, 70x58.40 mm, 70 trim, H trim (49 lbs/min)

After finding this info, I searched for the Garrett part number 409179-0024 and was able to determine that my compressor wheel is absolutely a U-trim. Here's a link to an eBay listing for an aftermarket version of the same wheel HERE. Notice the measurement provided in the title of the ebay listing and in the description. Now, here is a picture I took of the compressor wheel on the turbo I have...

Bullseye never offered a "U-Trim" turbo for a DSM, so it's highly-possible they were selling U-Trims as V-Trims the entire time. I have two "Bullseye V-Trim" turbo cores here and both have a 54.2mm compressor inducer.

While I appreciate that you went out of your way to prove me wrong in reference to the name of a compressor lineup from 10+ years ago, but the entire T04B series hails from a T4 platform with HUGE (1.00+ a/r) turbine housings. They were slow-responding, boost-limited turbos in their natural habitat....which would've been constant-rpm diesel engines like John Deere tractors making 6-8psi. Right or wrong, 1mm of compressor inducer spec doesn't make or break a compressor's ability to perform in most cases.

These turbos went over like a lead balloon on our platform. You can't take such a compressor and adapt it to a wastegated turbine housing with less than half the originally-designed a/r and expect it to work out too well. The early Holset H1C's have the same problem...some will even full-throttle surge themselves to death if you're running enough boost.

I had one for a few months.

It surged so bad that it eventually wore out the journal bearings and developed nasty shaft play.

I wouldn't recommend that compressor wheel for a DSM.

Yup, another ex-user here. My experience was pretty similar; lots of surge, and then it blew. Good learning experience I guess; made a much better choice on my next turbo.

RavenX said:

I used the Vtrim. I had to get rid of it because it would surge on my built 6 bolt at only 18psi while other people running stock motors were pulling almost 400whp which was really odd to me. In the end i went for the t04b 50trim and haven't looked back ever since. According to dave the vtrim is not a very forgiving turbo because of the map. Its up to you which one you want but i would just get the 50trim since its tried and true.

Dyno results:

Slowboy said:

Bullseye T04B V-Trim:
15 PSI: 249 ft/ lbs 302 WHP
20 PSI: 321 ft/ lbs 329 WHP

http://www.slowboyracing.com/downloads/dyno graphs/TO4B V-trim Test #2.JPG

http://www.slowboyracing.com/downloads/dyno graphs/TO4B V-trim Boost Graph Test #2.JPG

We did use the low pressure WG actuator that was sent with this turbo. It did show signs of not being able to hold 20 PSI to redline, so boost was actually about 18-19 PSI. We did also run into a little bit of compressor surge when we did try to tighten the WG actuator down to hold more boost. Of course, at 10:1 compression, and only running about 16 degrees of timing, this may have been a culprit as well. However, in trying to keep the testing on a level playing field, we worked within the given parameters.

Later, in regard to the wastegate function on a different Bullseye turbo:

Slowboy said:

Well, it seems every internal WG actuator we test on a DSM all have the same problems. We try to tighten the actuator arm up (to make turbo spool faster by holding flapper shut longer) and the boost spikes. We loosen it up and spool up goes down the drain.

Finally, the Evo III 16G:

Slowboy said:

We had only limited time today to get the test done- we had a few dyno appointments. We did manage to spend some time with the MHI Evo III turbo however, notice on the 15 PSI graph the boost crept from 15 to 20 psi.... the opposite problem we have been having! This was an unported turbo with no 34 mm flapper to help control boost creep. It was only an issue when we tried to run less than 20 psi however.

15 PSI: 290 ft/lbs 344 WHP (crept to 20 PSI)
20 PSI: 344 ft/lbs 344 WHP
25 PSI: 400 ft/lbs 375 WHP
30 PSI: 436 ft/lbs 397 WHP (fell to 23 PSI at redline)

We can easily make 400 WHP if we wanted to run more timing, or if we were on our old 2.3l motor we liked to beat on back in the day! We will have this turbo back on once we go external as well.

A friend of mine gave me this turbo a little while back and I am finally getting around to figuring out what exactly it is and if its worth while to mess with. I did a little research and found that it apparently came off of an international of some sort, I can not figure out much more than that. Any help will be greatly appreciated, I can take some more pics if needed.


edit: I forgot to add that it has virtually no shaft play.

Thanks in advance

Trying to figure out what turbo is in my car but its not stamped just says 49178-0 0 no #s stamped to identify it. Does say TD05H on it as well. Starting to wonder if its a cheap ebay knock off or if its actually worth keeping.

The picture sucks and is hard to see the writing. Ill have to take a new pics tomorrow when I get home from work.

Take off the intake and take a picture of the turbine, that'll make it easier to figure out.

It does not look like an ebay turbo. Sometimes the numbers are stamped very light and hard to see.

Looks like it might be a S16g after zooming in on the picture.

After getting some better pics it is indeed a small 16g. Thanks for the replies

I'm assuming this is a eBay knock off, just wondering if you guys have seen it before.

Never seen it but definitely looks chinese

Ya I tend to agree. Don't really care either, it came on a donor shell, and its basically new. I will probably just put it up for sale.

Yes, the ones that actually say "turbocharger" are Chinese. So are the ones that say "EVO3" or "EVOIII"

Chinese. Cost $175 new...probably worth $100 or less if it's been used.
