Holeset turbos
alright ya'll i need some help, i'm completely ignorant when it comes down to turbos and **** like that. guy has a holeset h1e turbo, he wants to trade it for a set of heads that i have. he says its equivalent to a 76mm t4 flange. somebody anyboy give me some info on this thing before i make a final decision. from what he's saying it'll be pretty good addition to the setup i'm working w/. he was putting it on his sbc but he decided to go n/a. if there's anything that anyone can tell me to help me understand all this please feel free to post.

if flows 70.1 lbs/min
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.

Misc.:
* Holset's don't spool slow. They spool faster than their garrett or mitsubishi counterparts. Diesel exhaust is cold and slow moving.
* The holset turbine wheel is a work of art. It has been shown to flow very well in a very small turbine housing. For example the hx40 turbine wheel in the small .55 ar bep bolton housing flows as much as a garrett gt35r turbine wheel in a larger .63 ar garrett t3 turbine housing. The hx40 with this configuration spools about 500rpms faster! You can upgrade to the .70 a/r BEP t3 turbine housing and have the same or slightly faster spool speed as the above gt35r with ALOT more flow per psi and consequently more horsepower per psi. This makes for VERY good pumpgas numbers.
* Holset patented map width enhancement. They do not have extended tip technology, but there compressors show more efficiency than their garrett or mitsubishi counterpart.
* They have superback technology witch leads to VERY, VERY durable compressors. The are designed to be overworked and underpaid.
* There are discrepancies all over the web concerning the compressor maps. Take what you hear/read with a grain of salt and a shot of tequila, and the worm.
* The holset is fine with stock 4g63 oil pressure from the oil filter housing. If you have no b shafts, you'll need a restrictor. The drain line is a garret bolt pattern. The feed line is different for different turbos.

that is supposed to be the equivalent to a h1e

That is a diesel turbo. It might not work the way you hope on a gas engine. It is designed to work at much higher boost levels and much lower rpms as suit a diesel vs gas. I have no personal experience but my gut feeling would be to pass and find a turbo better suited to your build. Is this for the 99?

dont forget brandnew BW box units are under $700. If I was doing a JY type build I would go with it, if I was doing a 'better' build I would buy the best turbo and misc parts I could.
