h1e vs hx40

[Alex Bland]

this might sound dumb but is the h1e and the hx40 the same thing? or is there a diffrence

 

[e85_4g63]

Hx40 uses a large "circlip" to hold the compressor cover to the back plate, whereas the h1e uses a v band clamp. There are other differences to (I'm sure), but that is the single easiest way to spot the differences.

Taken straight from every holset thread...

H1E/WH1E:

The Wh1e is like it's little brother the Wh1c. It mirrors the hx40 8blade in every way except that it has a v-band compressor cover and a 4bolt chra-turbinehousing pattern. It will consequently bolt into the hx40 bep bolton turbine housing and this is plenty of flow to max out its 60lb/min compressor.

The h1e is like it's little brother the h1c. There are different size compressors. . . BUT there are also different size turbine wheels too. Check measurements before buying this turbo if you plan on running a BEP turbine housing. There are lower flowing compressors than the 58mm 8blade that are out there. So this turbo may not flow any more than an hx35 if get the wrong one. You need at least a 58mm compressor inducer for this to be a worthwhile turbo vs the proven hx35 or 8blade hx40.

The Turbo Tech forum would be the appropriate section to post this question. However, this is such a easily answered question had you done 5 minutes of searching its going into the Newbie Graveyard.
