yes VH3, a but off topic but what would be the difference between a VH3 and VZ60 4kops ?
Same model but it calls out as Suzuki as the OEM part number 13900-49xb0 is my assumption that this is the Cat 2 cylinder turbo correct. IHI is not one that releases break downs and specs on their different turbos. Meaning wheel inducer and exducer sizes actuator opening psi.

Again the Spec No. is "VH3"

Ok, now i understand your post. So basically are you saying everything after the VH3 has no value with respect to product change. Interesting.
yes I never read into the other numbers. I am now trying to find out what they mean guessing one is some kind of serial number. If I call IHI they want one of two number either their part number or the spec number.
It really is not uncommon for OEM's to change part number and really never change anything. Caterpillar will even have one part number for something that is used on a off road piece of equipment and another part number for it that is used on road truck even thought it is the same exact part.

Very true
Interesting.

would be real nice to know wheel inducer and exducer sizes.

I would bet the “395” stands for 39.5mm inducer diameter.
Pretty easy to do, just measure it with a caliper.
That’s not going to tell you a whole heck of a lot tho. Wheel sizes used to be a good way to estimate the amount of airflow for a turbine and compressor but with all the technology nowadays it’s almost useless. Depends a lot on blade design. Tiny wheels flow a lot more than they used too.
If you were to convert over to say a Garrett GT2860 or even a different turbo with the same size wheels and trims as the stock unit, more than likely the tune would be pretty far off and need tweaking due to differences in intake and exhaust flow.
Not to mention the hot side a/r is unknown for the IHI stock turbo, that’s another variable.

Very good point..
Maybe one day we will have the ability to tune our own.......Used to be fun driving to work with the laptop, stopping at the gas stations in the morning to reflash, keeping a spare pcm in the trunk incase i bricked it. Lol

No the 395 does not otherwise the number would be the same on the two examples pictures above. yeah too many unknowns i guess was hoping to be able to utilize a 1100 turbo but finding the specs seems almost impossible.

Here is the new one. Much better and i would say how it should be. Works for me
You turbo experts can decide.
New and cam almost on top the turbo
