I'm just waiting on Nicks shipment to get this h1c running!!!! Maybe it's a cheap alternative to the 50-trim/hx35/20g/s200bw/etc turbo.

How would that turbo be cheap if it mechanically fails?

Why would it fail???

Read my ? again and carefully! I put the word "IF" it fails meaning that "IF" it were to fail mechanically,it would probably be much more expensive to fix compared to regular conventional turbo.

Sounds like you guys are not on the same page. lol

From what he posted, he said maybe the H1C is a cheap alternative to the others. The H1C is the conventional turbo that he bought, not the complex one I just picked up.

I hope I have it by next weekend so I can take it apart and measure the wheels.

It will probably be a while till I get it on the car. Its going to take a lot of fabrication to fit it.

School just started back up, and I need to buy something cheap for a DD. Sucks having this as my only car.

Will this HX35 with external gate mounted here have clearance issues? Shed some light on it for me. I do have other pics I'll be uploading here soon.

Here's number two. I guess I could find another way to mount the WG and grind off that flange although I'd rather not.

It may or may not fit. Your biggest problem with the wastegate actuator mounted on the compressor housing is you can't clock the turbo. Hopefully it is close to where you need it. How is it situated compared to the TH? Are you planning on using the HX35 stock housing or a BEP housing?

I had my WG actuator mounted in a similar location. With no passenger side fan it fit fine. I used a 14b actuator with the mounting tabs slighty bent to fit.

Edit: Your second picture didnt show up when I viewed the post.

JWoodley · 01-26-2008, 06:46 PM

Aero, try the second picture again. It will give you the relationship. It is already in a BEP housing w/ 38mm internal gate. If it doesn't PM me and I'll send it to you or try another host. Josh@GRE can get me a mount that goes on the backside of the compressor housing which might help a tad.

I can see it now.

I think that should work, or it will be very close at least.

Oh I saw that map or mention to it a ways back and thought mass flow with in lbs/min. 87 lbs/min is actually perfect for what I want out of the turbo. And that is around the 45-50 PSI range.

And as far as the VGT turbo. I wouldn't worry about a controller. Gut the electronics and just kept the solenoid if it's one of the electricity actuated TH's. Then you can either use a hobbs switch or your PCM to control volute sizing.

And for the HX35 actuator issues. That current config will not fit on a 1G. I don't think the 2G shares the same front mount under the turbo so it may work on a 2G. I just took the Holset actuator and took out the torch and bent an extension rod that came off the stock actuator when the turbo was clocked correctly.

Without reading a bunch of posts, can anyone tell me if the alignment dowel for the comp cover is simply removable or will it have to be ground away?

There is no alignment dowel.

I'm pretty sure the controller is a stepper motor and not a solenoid. I may have found something that will translate the PWM boost control signal from my MS2E to a stepper motor driver. If it doesn't work I will probably find some kind of solenoid actuator to adapt ot it.
The electronics on the turbo are just the VGT actuator, VGT rack position sensor and shaft speed sensor if I understand it correctly. The electronics are all in the ECM or a seperate box in the truck.
Here is a picture of the geared arm under the VGT actuator on a similar turbo. This is an HE431VE, mine is a HE351VE instead.

I'll have to figure out more when it actually gets here.

The one in the pictures a guy on hondatech is selling.

So all that is reqired to clock the comp cover is to take out the snap ring and re-clock?

dsm-onster · 01-27-2008, 04:39 PM

No. It is not like an MHI turbocharger. It has a series of bolts that grab a circular lip and seal the compressor cover with an o-ring. Much like a garrett/turbonetics compressor. Loosten the bolts and clock it. The bolts close to the block are hard to get to with the turbo installed. My h1c has a v-band clamp instead

. That's about the only benefit of running an older holset.

kicker91laser · 01-27-2008, 06:45 PM

My holset has a snap-ring on the compressor cover, not the bolted clamps.

No, the hx-35 and the 40 do not have bolts holding the compressor cover on nor do they have a O-ring.

Yes, you are corect. You can pull out the snap ring and clock the compressor cover however you want.

The snap ring can be a real bitch to get on and off due to its size. After doing it a couple times to get it exactly right I found out its fairly easy to put a rod, piece of pipe or wood in the compressor outlet and use the leverage to turn the housing without removing the snapring. MUCH easier that way.
