Hx35

[RedGST98]

I just picked up a Holster and the intake is WAY bigger than my old T-28.. I know they sell them but does anyone know where I could find a intake pipe that will fit a hx35 as I want to run my 2g MASS.. If not do you think a reducer would hurt it to bad with air flow coming into the turbo?

fp intake pipe with a 4" coupler, or make your own. And it's Holset not holster

you are correct.. sorry long day.. and thanx

Put this in your holster.

FP DSM Aluminum Intake pipe

This is a newbie question like no other.. I have never had a external wastegate in my life.. I have one now.. my question is how do you hook up the wastegate with a boost control if the compressor housing does not have a fitting?? I know you can tap a fitting but makes no sense how it could have been hooked up before if its not there now... any suggestions would be nice to have...

 

[1990AWD]

That's because Holsets are found on diesels that sometimes don't have wastegates, and if they do, they source from the intake manifold.

 

[bryanwheat]

As you said, you can tap the compressor cover or you can just run a line from the intake manifold. I would personally just pull the cover off and drill and tap it. I like to have the source closer to the turbo.

 

[RedGST98]

sweet.. thanx guys... I had heard about pulling from the manifold and even the bov but it can cause the turbo to over spin... im going with the tapping an elbow.. thank you guys....

 

[zcoh2gdsm]

never tap the bov line, it should always have a direct line to the IM.

 

[RedGST98]

aye that is what i read.. I would never do that.. never sounded right to me.. thats why I had to ask on here the correct way

 

[bryanwheat]

You CAN do it as long as you aren't running a boost controller. The reason that you don't want to do it with a boost controller is that the controller will bleed off pressure and not hold the bov shut as it should under boost. But better to just not to it at all as stated.

yea i would tap into the intake manifold i work at a high performance bmw turbo shop and weve had problems wit cars that have the waste gate plumbed off of the turbo housing cause of the loss of boost across the system so if you tap the manifold your covering your boost loss ....

going from the housing if there is loss then it just takes a bit longer to get the boost to operate the diaphram on the wg to open at the correct boost lvl right? so going off the manifold the boost will be there faster so it opens faster?

or am i far off on that?? Just bought a nipple to tap so yeah... let me know the deal.. using a boost control wont effect it if its on the intake or housing other than the boost loss in the system??

Yes, but your still covering your losses if your measuring boost at the intake manifold and adjusting from that even if the mbc is sourced from the compressor housing.

The advantage lies in having as short of vacuum lines as possible to reduce boost spikes.

You would figure the line would be shorter to the housing then as you would have to run it up to the manifold though wouldnt it??

That's exactly what I'm saying.

 

[bryanwheat]

I am sure that all the turbo manufacturers that put them on the compressor housing are stupid huh, along with just about every stock turbo out there. You want it as close to the turbo as possible.

 

[turbodeclipse]

well tapping the manifold for the wastegate gets you the true boost entering the motor tapping the turbo gets you the boost pressure at the turbo you may only have a .8 psi loss through the system but we have seen on our dyno trying both ways big differences in boost logs weather it be making earlier or later or holding boost better the lenth in vacuum lines is minimal when compared to a 3in charge pipe

 

[RedGST98]

Thank you all for the input... I had went out and bought a elbow so im just going to go with the tapping the housing...

I know everyone has they own way of doing stuff.. and .8 or what not isnt that much of a loss.. not enough to tell on a driver for the most part...

Thanx again guys... now to tap... and get the drain lines all set..

 

[RedGST98]

done..

 

[96gsxwi]

nice!

have you taken it for a drive?

 

[1990AWD]

Good job, but those 90* fittings on your drain scare the crap out of me. I'd switch to something with a simple 45* at either end of a line. Something like this but I would add another 45* on the end. What is the size of that drain anyway?

 

[RedGST98]

nice!

Took it for a short drive yesterday.. Replaced the lifters to the revised 3g lifters so they were knocking.. so took it slow to let them fill up and quiet down.. but it drove nice as could be.. will be replacing my injectors to 1000cc here in a week or so...

the bottom end is the 2g oil drain that is just about 3/4" Its the biggest of the drains.. I had talked to justin and read around and found that it would work with no prob. The 90's yeah I dont like that much either.. but it all fits up pretty good with no stressing on the hose or drain pipe...

 

[JusMX141]

Your drain goes down, then pretty much straight back into the pan. That's not going to drain for shit.

From that pic it looks like it for the most part.. but if you saw if from the side you would see it better.. It all angles down to the pan.. the pan is the lowest spot the bottom is angled at almost a 45 going up to the hose as the hose is going down to the pipe.. the 90 is also angled down for drain.. still think it wont work?? let me know.. dont want to blow my shit up...
