Well my concern is that now the oil is going to be taking that much more of the heat out system. Even this winter after hard 3rd gear tunning pulls my oil was thinning out and oil pressure was droping down at idle dangerously low on my E16g. My concern I guess is over cooking the oil this summer. I ordered a external oil filter housing from MACHV the other day. Just wanted to know if anybody else had any thoughts on this.

I've had no problems. I'm also feeding my Garrett from the head where many claim the oil pressure is very low. I have had no problems with my external oil cooler setup and where my turbo receives the oil for 4 yrs now. When I install the holset I will feed it from the oil pump with a restrictor inline. Oil thinning out and low oil pressure is not a problem in these motors especially with the addition of an External oilcooler setup different or similar to what the 1990 1st gen GSX's had.
I was beating the life out of my car in late Sept early Oct doing several 140+ mph runs(20psi boost) WOT and not a glitch with my oil pressure. I only had heat soak issues because the day was also very humid (Temp in the 80's to high 80's believe it or not). Now I will be putting in an even bigger Spearco intercooler and cool air forced ram induction feeding the turbo inlet as well to deal with the heat soak issues.
Wow pretty radical! Must of been alot of wrk for that master piece composite tube.
I like mine because the air is cold and being more so forced in as opposed to the nice cold air idea you have.
I think my Holset HX40 will love the ram air immensely!
I would like to find a way to vent the hot air out. I'm gonna use a side NACA Duct from a RX7 TT and have it molded into my hood. By the way ,where did u find those nice hood locks?
I found a good deal on a wh1e (There's actually 9 available if anyone is interested). I've looked throught the holset pages for a while now, but I'm wondering if anyone has found which part number or series of the h1e's will work for the bolt-on housings? If anyone can tell, the part number of the one I'm looking at is 3535870. Thanks
All wh1e/h1e turbine wheels are the same as the hx40 turbine wheels. And all wh1e/h1e turbine sides have the same bolt pattern as hx40 turbine sides. So the hx40 BEP housing will match.

Matt that is wrong. Their are several turbine wheels on the H1E's. I happen to have one that is not the same size as the HX40. It was the reason I bought a HX35. Now I'll just have to use the H1E for my turbo truck project.

Yep Matt can give you some very good info sometimes. But when he gives to much WATCH OUT!!! Get's expensive!!!
Thanx for the edit. I just pulled my wh1e turbine housing and tripple-checked the wheel. This wh1e has assembly number 3535870 (same number). It has the 2.51" minor dia 2.99 major dia hx40 wheel that bep footprints.
3535970 is the assembly number for the wh1e on the volvo d7a: a bus, I think???

Yep tried using the 19cm housing from my HX40 on the H1E turbo on my dad's International combine with an 8.3 cummins and the turbine wheel was too large to fit.
Thank you guys for the info; and matt, yes these are the one's I'm talking about. I didn't want everyone else to pick one up before I had a chance to . I was reading that link you posted and noticed at the end that he had a hard time getting it to fit correctly. Does anyone know if the bolt pattern would be the same, or if not, a machine shop could fit the h1e into a hx-40 turbine housing for sure? I want to make sure befoer I go this route!
In the last post, another guy is talking about running a garrett b cover sized housing. He was looking at an hx30. My h1c fits in my hx35 turbine housing just fine. My wh1e has an identical bolt pattern and cartidge dimensions as my h1c. The turbine wheel foot prints between the hx40 and this wh1e are identical. It will work.

This is a Ford Sierra demonstrating what a full twinscroll mani and turbine hsing H1E setup can do. Key here also is to notice and listen to the throttle response of the car. Especially at the very end of the video when the guy drives on the road sorta normally while shifting gears. There is almost very minimal lag. This is really just a testament as to how really well the full TS setup works on the HX40,35,and the H1E turbo.
Well If anyone wants an h1e turbo, compareable to the hx-40, I offered this guy on ebay 275 and he sold it to me-BRAND NEW!!! Search for new h1e holset. Needless to say, I'm excited. So can I use the wastegae actuator off of this turbo, and be set?
I asked the seller the sizes of the wheel and he sent me this:
Comp 58mm
Exhaust 65mm

Most of those actuators are pretty high pressure. I tested the one that came with my HX40 and it didn't start to open till 25lbs.
