Turbo spec compilation thread

The Hx40 does not come in a 12cm or 14cm housings. They have 16,17,18,19 and 21cm housings with T3 T4 mixture.

The HT3B can come in a 32cm housing as well.

The HX 35 never came with a 60cm comp wheel.

Added because of the 35/40 hybrid commonly used and compatibility. Same goes with a few garretts. Stuff you don't find on the website.
 
As far as I can tell they are all divided. The T4 housings include 16cm, 17cm, 18cm, 19cm and 21. The 16cm and 18cm housing also come in a T3 version.
 
Also the Hx40 60/86 comp wheel comes in a 8-blade, 7-blade and 6-blade version. The Hx35 56mm wheel can come in the 8-blade and 7-blade version as well.
 
HE351CW (non-VGT) has a 68x60mm turbine wheel.

HE351VE (VGT) has a 70x60mm turbine wheel

They both use the same 60x85mm 7 blade comp wheel, same one as the 7 blade HX40 ~65 lb/min, depending on where you read it.

Was just going to find the time to hand calculate it. Wasn't aware of them being different. All the same that i've seen.

The inducer size is the same between them, but the BB turbos have a 78 trim, the JB turbos are an 84 trim.

He351cw has a 68x58mm turbine. Not a 60mm exducer.

The turbine on the Hy35,he341 and he351 are all the same.

Not according to the specs I have seen, and from phone calls from Holset. I never took calipers to them, but the HE351 has been called a 60/60/9 in everything I have seen. The HE341 is smaller and your post is the first I have seen where they were called the same.

Not saying I have it wrong, just a lot of info stating it's a 68x60.

i have 2 of them and they are both 58mm. If people really want to, i will got take a pic with the caliper on one. The only thing smaller on the he341 and hy35 is the Compressor wheel.
 
HT3b's also have a 27cm housing. From what I've seen, there are HT3b's from Holset and BW/Schwitzer. I think the Holset's have the odd numbered ext. housings and the BW's have the even numbered housings. Seems like the Holset's are divided and the BW's are not divided.

The flange on any HT3b is not a T6.

Interesting. I also noticed that BAE said the same thing.

Weird that I got 68x60 from holset, but looking at my notes they also said 60x82 on the comp wheel and I know that is wrong!

So 58mm it is, another reason I am super happy I ditched it. It's nice having a turbo that 99.8% of the time has more boost than drive pressure, instead of the opposite.
