usedkubotaman - do you remember the exhaust output size of the gt1752?
so if i am looking at this calculator correctly and the maps.
it looks like the gt1544 would be a good match.
this turbo came on the vw 1.9l TD
I put my target power to 120 hp approx 100hp at the wheels.
i will keep an eye out for this turbo in any junkyards local.

Hmm, interesting information! I just split the difference between the recommended intercooled and non-intercooled BSFC to try and be more realistic, but I'll have to play around with the numbers you provided. Another consideration is that I don't think that our engines have the E-TVCS system listed on the link you provided, but I have no idea how this would impact. I would guess that the best way would be to see what BSFC number best supports our real world experiences.

My turbo showed up yesterday.
I am amazed with the exhaust flange/port. I am expecting a major improvement with my header! things will flow smoothly.
A T25 flange has rectangle port that measures 1.94 x 1.57 with .375 radius corner approx.
the GT1752 has a 1.52 circular port. The exhaust residue on the flange shows the restriction.
I am making my flange with a merge collector from 4 x 1.25 OD to 1.5 outlet. Should increase velocity right before the turbine and be SMOOTH
This is the merge collector I am going to order sooner or later. got a couple other things to pay for first.
4-1 Collector, 1.25" Inlets, 1.50" Outlet, 4.5" Long, Mild Steel Columbia River Mandrel Bending
I am also getting my mandrel tubing from here. Going with their ultimate builder kit the first time. I think there will be enough tubing for two complete headers.
Flanges are available if anyone else wants to tackle this project.
i will also be rebuilding this turbo. got some play in it.
Pictures follow.
Thanks

Another little update. Finished the t25 exhaust flange for the GT1752
the inlet isn't exactly centered. I don't know why but it was off .020 in both directions
I made two flanges. Not sure which I will use until I get the merge collector here.
one is stepped for the collector to sit into and get welded.
The other is a thru hole .030 bigger then the od of the merge collector and I could recess the merge into the exhaust housing. the ID of the merge collecor is 1.37 OD is 1.5 and the exhaust housing ID is 1.530. anyways i wont be doing anymore with the header until a little funds come in and I can order the tubing

Here is a video I promised. taken me a couple days longer then I hoped. Been 100+ here lately and didn't really want to be outside after work. It was only 96* when I took the video at 6:30 pm.

as you can see cranks really easy and fast. I am not much of a movie maker so this is my first real attempt.
Thanks

Lookin good yellow68gto, only thing is you keep saying small block chevy, but the Big block has the same bolt pattern, as do many of the 4&6 cylinder engines in the GM line. Manuel and automatic,front and rear wheel drive. 2&4 wheel drive. So it opens up along list of available gear ratios, mounting locations,vehicle options, and who knows what that the mind can come up with. It would make it easily adaptable for conversions in boats,tractors, ect. If you decide not to use the bobcat oilpan I sent with the engine, you can send it along. I think your going to need to get AC for your shop.

i do need to expand my description and somehow incorporate some of the other types of motors. i figure mostly people can use the transmissions from a sbc or bbc also the 4.3 is the same. works really well for the s10 crowd. i will be making one for the 2.2l chevy guys to.
Dan please don't think I have forgotten about you.
the oil pan is currently being used as a template and making a flange and hopefully will make a front sump or rear sump weld it your self type kit soon. But i will be sending the pan back to you along with some other goodies for you to check out here soon.
how has your 27 been coming along? did you ever figure out what you want to do with the isuzu?
thanks

Yellow68gto: My round about point is kind of a small block chevy is like talking about an 8 track or even a cassette tape. Depending on the age and background, a lot of people don't associate with there auto world, when in fact actually is, when cross checked with exchange lists. (What fits what and what was it used in). The thing is with GM the interchangeability over the years and models is enormous. ( your not limited to s10 stuff, when you would really like a one ton Nv 4500, or the 5 speed from my 56 gmc 6500). As for the oil pan, if you are making use of it, Great. I just hate to see things get tossed when there are people looking for it. (Anything). It's easier for the wife or kids to get rid of it when they know I can't use it anymore, than it is for me to find it free when I do need it, the 4x4diesel ratrod is almost drivable. (1927 chev truck & 1982 chev luv 4x4 diesel). I might have to ship the c201 isuzu out so you can make an adapter for it similar to the 2203. Shipping is cheap.
