You'll need to make a port in your blower plenum like this:
Make a T so you can divert the air as needed like this (this was the first draft, it was too big and ugly and never made it to the car before I completely redid it):
Then make a diverter valve. Here's my latest design, made from an e-cutout, a wastegate actuator, and some aluminum brackets that I fabricated:
Then make a control mechanism for the valve, I use a Hobbs switch and a on/off boost control solenoid with a small bleeder hole, but I may set it up using the AEM EMS and a GM boost control solenoid later.
You'll also need an adapter to convert your TB flanges to 2.5" pipe to extend your TB to the other side of the T. I paid a guy to make a CAD file of my flange design and had the flanges hydro-cut, then had a guy weld 2.5" exhaust pipe onto them. </TD></TR></TABLE>

Thanks Joe,

Re: Question. (80 dolla crx hf)
Roger is now working on an M90 set-up:
https://honda-tech.com/zerothread?id=1997913
I took over development and testing of the twin-charger and the latest version was just finished last week.
The hatch is running but I haven't tuned the car yet with the new turbo so no numbers yet and because of my new job it looks like I won't be able to get the car on a dyno for a couple months.

Re: Question. (clemsonhatch)
So is the cross-over system still the hobbs/mbc/solenoid deal? If I understand this correct, Roger used a 4-way solenoid valve with the dual nipple actuator? I was thinking the hobbs vents the vac port at very low vac and un-vents the pressure port. This would allow the actuator to open under vacuum easy and also function with boost, but not need a normal bypass. The actuator spring would only need enough power to close the TB.
If not, I would suggest that's how it gets done. Grainger sells a 4-way solenoid valve (12vdc continuous) for under $50, and would work great. It would do vacuum like a normal SC, but spool instantly to the SC psi, then to the cross-over psi (and phase out the SC), then spool to the turbo's target boost.

Re: Question. (HiProfile)
It's the same cross-over system Roger had, why mess with a good thing? Everything else has been tweeked to maximize flow, all the 90 degree bends have been eliminated to help out. We'll see if it helped out once we get it on a dyno. So far it feels amazing, like having V8 torque with no lag

Re: Question. (clemsonhatch)
If I remember correctly I believe I have seen this at a local Atlanta Region autox. Amazing setup by the way. I wish I had the time and funds to tinker with such contraptions.

Re: Question. (blaze the chemi)
Its not that I'm trying to change it, I'm just trying to GUESS how it works. He never posted pictures of all the components, nor a very detailed description of how it worked. I would like to do this down the road, so I'm really curious how it was worked out.

Re: Question. (HiProfile)
couldnt you have made the same power with just the turbo?, i guess im assuming you replaced the lag with the supercharger correct?

I could make more power with a turbo alone. The goal was to have instant usable gobs of torque and it does that.

Thanks, it's a work in progress and keep me busy. Yeah both Roger's coupe and my hatch have raced at ATL races.
But this year I've been driving an STS civic It's a little more pax friendly

Re: Dual-Sequential Chargers
On my way to doing the same thing.
Except I'm using a HE351ve => SC14=> intercooler=> 70mm tb=> Z6 IM=> to a d16z6/y8 w/ vitaras and tt rods.
The SC14 has an a/c clutch and with it disengaged I route the flow around s/c through a bypass valve that is mechanically inked to a IAB type actuator from a h23 IM.
The actuator is controlled with a purge valve controlling the vac. signal via a secondary circuit from my full throttle switch.
The VNT on the He351ve is controlled by a wg actuator rigged where the circuit board use to be. the boost pressure control through a Apexi valve linked to my modified p28 using EcTune.
The master switch for the a/c clutch actuation for my s/c is the stock A/C switch on my dash.
I get some inspiration from this build and the DutchAccord build thread on here I read a while back.
Would have liked to see more results for this build.
But both of these build seams to be a little over complicated

im really interested in using that holset turbo if you have found a way to use the vnt on the he351
i would be using it in a vw 1.8t
if you don't have a build thread could you IM me with more info on how you have setup the he351 to control the vnt please

Re: Dual-Sequential Chargers
Yeah I have a build thread on three other forums and after seeing how much people on here treat non-baller build threads, I'll probably not post here.

Been working a lot this year...should have posted this a long time ago...sorry.
Here is a video of the results for this build:

Listen to how it instantly pulls all the way to redline when he steps on it
Here is a video from earlier this month:

Anyone interested in this powerplant PM me, open to cash and Ktrades. I want to get into wheel to wheel with my hatch and there is no class where I can run with this boosted set up w2w. I can run time trials and do hillclimbs (which I will do this year if time permits) but I'd like to go wheel to wheel eventually. Not in any hurry just thinking aloud...

SPSS3 Revalved Koni's, coil-over sleeves and hypercoil springs. GS-R brakes. Bunch of different wheel/tire set-ups.

Re: Dual-Sequential Chargers
Id love this setup dude! how much would you sell the setup or part out the turbo kit/desighn. Im thinking this wont work with a lht manifold. That is so sick everyone i tell about this tell me im stupid and its not possible haha lol.
