Help id this turbo

[ezrollin]

I've measured both the compressor and turbine wheels.The comp:2.299 ind./ 2.675 exd. Turbine:2.515 exd. / 2.895 ind. Checking the specs for a T04B H/P trim I noticed there were slight diff. in specs from brand to brand. I measured to the 1000th,that's close! These are the spec's from one of the spec sheets:Comp: ind. 2.298 exd. 2.750 Trubine:exd.2.544 ind.2.922
If you round them off they equal a H/P trim.

Here's a place that will help you calculate trim by measuring the ex/in-ducer...

So that turbo is basically like a T4 correct? Could be some what equivalent to a Hx35?

I don't know because I haven't checked the spec's for a Hx35. I found out by checking different turbo spec sheets that what one brand's spec's are for a given turbo aren't exactl the same as another brand's. It had trim specs real close to an H comp. and P turbine. Another thing thats confusing about turbos is the diameter of the comp. air inlet,some are larger than others but but flow the same cfm,so there must be a reason they make them different sizes,maybe fitment.I did find a list of diameter requirements for turbine exducers and this has a 66mm good for 450 - 500 hp.

got to finish this house

I'm a contractor ;p

[ezrollin]

Oh,mine will be in the planning stage for sometime,got to finish this house before I can start and I've got a blazer V8 that has 90% of the mechanicals done that I have to finish before my turbo project.Though it pays to start researching and gathering parts well in advance.

Yeah, I know.I wasn't going to use this turbo for my 3.4 project. It's a new one I picked up for a 5.0 but decided to do the 3.4 instead.I'm gonna sell it and want to make sure I don't sell someone something they can't use.How's your project coming along? Where in FL. do you live,not trying to get your address,just thought I could see your car when it's finished. I live in W.P.B;but wiil be moving to Inverness FL. in a few months.

Getting there, waiting for MS to show up before the turbo install (got all the parts). I'm in Broward (Coral Springs) I'll PM ya when finished and we can get together. Lemme know if you need anything to help speed up yours .

.84 turbine is going to be laggy on the 60*. If you wnt boost at lower RPM's, you are going to need a more restrictive turbine.

Got a battery for my digital caliper and took measurements. I looked at spec charts for a couple of different manufactors as I couldn't find any for a Schwitzer. I know the turbo is a Schwitzer TO4B from the tag on the compressor and an .84 ar turbine.I determined that the compressor has an H trim and the turbine a P trim. What I haven't found is how much air it flows,anyone know? Also, I had seen inlet diameter sizes required for given flow rates in one of my searches but can't find it now.

[ezrollin]

I t appears that I took the measurements wrong after checking a few turbo sites,I do know the compressor is a S chwitzwer T04B and the turbine is a masterpower w/.84 ar. I'll do the proper measurement later.

That's all I found.

Turbine is a MP .84ar,61mm id outlet/V band,4 bolt divided flange. Compressor has a 60 mm id inlet / 44mm id outlet and a tag thst says "Schwitzer" T04B. Was in Borgwarner box.
