holset HE351cw

[benjimatt]

Hey i jwas thinking about getting a HE351cw. I was wondering if the bep housing could bolt up to this turbo. I was looking it up and I saw that it has an electronic wastegate thing that most people just plug up instead of trying to use it.

(This is not a vgt turbo that is HE351ve)

 

[benjimatt]

Oh, sorry, you will have to relocate the alternator but you were doing that anyway. No it dosent even come close to the block. You will come close to the rad, and will not be able to use the stock fan either. I assume you cant test fit anything cause you still running the little turbo eh? Since you will have to spend lots of down time designing and fitting a down pipe, you will have time to try differant positions for the turbo.

I wasnt really planning on relocating the alternator . Maybe if I absolutely have to. but that is not in the plans as of now.....
Im probably not going to be able to but it on my car for a couple more weeks. I dont have a garage right now but im finally moving...in two weeks to a place with a garage.

I think one of my local members my have a block that i can do some test fitting with hopefully !!!

 

[stace]

Thats what i did with my saturn project. I asked a guy for his dead blown block and used it as a mock up for all my pre biuld-ups. My first custom turbo manifold and down pipe was fabbed on my mock-up block months before install, and when I took a weekend off to put the turbo on the car , the down pipe wouldnt fit in the car. I had to make a new one with the turbo in the car...in 4 hours. I fully recomend taking the car off the road for a week and designing a downpipe with the turbo on the car. unless you can find a spare car to fit it on or a prebiult downpipe.

Hopefully ill be posting the wastegate and manifold that ill be using today

 

[benjimatt]

I got my 38mm wastegate and 2g manifold today.

Looks like its already ported for the 7cm turbine housing.

 

[benjimatt]

It came in today!!!

Looks like it has some compressor damage. It has a few chips in the blades.

 

[benjimatt]

yeah i noticed that. But it has no shaft play???

 

[toofast82]

Yeah, the chips on the compressor wheel are no good. It may still work, but not as efficiently. Not sure if it is enough to throw off the balance or anything like that?

 

[benjimatt]

For anyone that is wondering I finally got this turbo bolted on. Its almost ready to race I need to get a wastegate pipe made.
I went with the revhard manifold. It only cost 220 straight from revhard

I have a quick question. SInce I have a big exhaust leak on the wastegate hole under the manifold would that throw my AFR off.

When I started the car on my regular settings I was all the way at 26:1 way to lean at idle.

I tuned it where its around 14/15. But now im backfiring. DId I add way too much fuel??

My wideband is on the downpipe.

 

[brian9397gsx]

you do not want to use heater hose for your return line oil tends to cause regular rubber hose to swell. if you have a hydraulic store in town or a place that makes high pressure oil lines. i would stop in there and see about getting hose from them.

Yeah, an exhaust leak will throw your wideband off. It will make it read leaner than it really is.

 

[benjimatt]

Thanks for the help I made it to my destination

So im really thinking about getting a 4" U pipe and cutting it where it is a 90 degree bend and using that pipe for a intake pipe.

The air should be cool since it will be coming in lower.

It will kind of me like a cold air intake, since it will sit low...

any thoughts?

 

[benjimatt]

Ok guys I have some problems :-(

First of all I think I have a lot of leaks :-(

I tested the car on this road and in second gear I didnt hit full boost till like 6500 rpms.


Ok yes I know that this turbo is big and that it will spool slower than a smaller turbo. But 6800 rpms :-( no way.

So eventually it stopped making boost at all so I pulled over and noticed that one of my couplers fell off :-( It was on the hot side right at the turbo so I knew this was why I wasnt making anymore boost.

So I still cant tell if my boost gauge works or not. If I suck on the boost gauge it goes to 30 vacuum. When I blow on the boost gauge I may be able to make it to 5 psi. When I disconnect the line at idle it is barely sucking. I have it teed to the pcv valve and the magnus intake, is this incorrect? I may try and put it at the throttle body.

When it is in my car on idle it shows no vacuum at all???
In boost it eventually climbs but it takes a while. It climbed all the way to 15 psi but I thought my wastegate spring was at 8 psi???

Some things are wrong and I am going to try and figure them out tomorrow.

 

[benjimatt]

Ok guys boost gauge works Smile At idle I get 17.5 psi vacuum and when driving and not accelerating my vacuum is 20 psi.

My boost is going up to 15 psi and sometimes 17 psi. So im just going to lay off the throttle completely until I install this fuel pump.

Now I have to install this boost controller.

Right not im running a line straight to the wastegate from the compressor housing. This will be changed soon.

 

[toofast82]

Glad to hear you got it going
What rpm are you hitting 15psi at?
I know your last post you had the coupler off and some other issues.
What kind of Half-radiator is that? Sorry if it was mentioned already

 

[1timehondalover]

How is your block clearance with the RevHard manifold?

 

[benjimatt]

Its just an ebay half civic radiator. Its 2" wide. It holds a decent amount of fluid. I havent overheated yet.

Right now im having weird issues. Its not getting full boost till like 6000 rpms but its going past 20. Something may be wrong with my wastegate.

 

[benjimatt]

SO the pipes are beaded and they finally stopped blowing off.

Things seem to be running fine. But im pretty sure there is something wrong with my wastegate
The wastegate spring is supposed to be 8 psi but whatever I do it always goes to like 20 psi!!!!

So hopefully in the next couple of days I can take the wastegate apart and see whats up. Hopefully there isnt much wrong.....

SPOOL!!! Im confused. SO no I have still not been able to get the boost leak test done yet. That will get done soon I promise.

1st gear 15-20 psi by 5500 rpms
2nd gear 15-20 psi by 4700 rpms
3rd gear 15-20 psi by 4000 rpms

I like the third gear stats. Im confused because I thought the statistics are supposed to be consistent in each gear??

Yeah the numbers look good for 3rd. I think most time when people are talking about spoolup, they are referring to third gear. No the spool will not be the same in 1st as it would in 3rd or 4th.

 

[dsm-onster]

^^^ Yep. More load on the motor in higher gears. Turbos are load based. The more load, the faster it spools. If you weigh more it spools faster too. More load. Those 1st and 2nd gear numbers look ok with a 3rd gear that has that boost by 4K. . .

 

[benjimatt]

I think with an exhaust housing of .65 a/r I should spool a little quicker.

Anyways I just took apart the Tial wastegate and it looks like I have a Large Blue spring which is 1 bar which is 14.7 psi. I'm not too sure why I am overboosting but Im going to run my lines to the eBay controller differently.

I had some extra pipe around (its a little bigger diameter but its just for measurement) I'm getting it cut the way I need it tomorrow.

My 2.5 to 3" coupler melted Sad So i'm going to get another one tomorrow but not autozones spectre Sad

 

[benjimatt]

Changed the setup and now its not going to 20psi!!! But it holds at 17 psi with the wastegate deactivated and with it activated (on the lowest boost) I wont test the boost controller further until this fuel pump goes on my car.

Oh and I now have a filter!!!

It seems the spool it a little better since fixing the piping. It seems that this turbo is slower than my 16g but maybe i'm just tripping??? It might be that I am use to spooling instantly .

Well now time for fuel pump install!!!

 

[dsm-onster]

Of course it will spool a little slower than a 16g. It has a larger holset turbine housing with a turbine wheel quite larger than a td05h 16g turbine wheel. And a MUCH larger compressor wheel

Get you a ball and spring MBC on and properly working. That will increase spool speed (and encourages spiking too).
