evo316g with big housing, w/ photoshoot

[DSMatMSU]

Well i got the new 'BiG' housing in, i wanted to stay with the internal gate if at all possible, and this is 38mm... i know i coulda ported, but this thing was a good price (215 shipped from bullseye) i figured this housing would do the job, and definately flow a lot better... (plus be able to sell the old one) thats an evo 3 16g mounted on there... getting that big ass ring clamp on there was a bi***, this housing doesnt use the old clamp style with a bolt, it uses a LARGE snap ring... but we handled that shit... anyway, next thing to get is an o2 housing of somesort, maybe with a dump, or keep it stealthy with one of the cast o2 housings, i dunno... im probably gonna match it up the slow boy cast manifold as well.... currently have a 3" turbo back w/ no cat... and 2g exh. manifold...
plan to install it tomm, definaltey looking forward to see how this works...

oh yea, 56k ppl plan on waiting, currently my desktop...

hmm been there done that

 

[blcknspo0ln]

did it help creep?

 

[16g-95gsx]

Screw creep, that could have been EASILY delt with on the stock housing with just a mild port job around the wastegate entrance on the stock flapper. Unless your wastegate solenoid is stronger than stock Id say buy buy to high boost until redline. A bigger internal wastegate isnt always what it seems, good for creep, bad for high boost.

 

[91-TSI-AWD]

Looks like my 14b . It helped w/creep; I recomend it.

 

[DSMatMSU]

i know i could have ported, been there done that.... but this housing is much larger, and i wanted to keep an internal gate if at all possible... if anything, its going to flow better... its not just the wastegate were talking about here... i figured it was a good all-round upgrade...
plus i had a bolt brake off in my original housing that i didnt feel like Fing with anymore...

ive taken the cheap way out of a lot of things.... but damnit i wanted to buy a cool part for my car... and 200 bucks isnt exactly busting my budget.... i mean, your gonna pay more than that for an external wastegate setup by the time your done with it....

the only problem i ran into... the waste gate arm hits the edge of my stock o2 housing(i guess you call it the flange? the flat plate the runners are attached to) so the wastegate cant open if it wanted to.... i just need to take a grinder to the edge of my o2 housing, and i should be fine... it just barely hits it...

so, i still havnt got to test it out...

 

[16g-95gsx]

You dont need an external, or any other larger wastegate not to creep is my point. And if 200 dollars isnt much, then why didnt you pay the 90 or less that it would have cost to have it professionally ported? My points is that with a larger surface area of a 38mm internal flapper, the forces that it must resist at higher boost are generally too much for weaker wastegate solenoids to keep closed, causing the flapper to blow open and suddenly you have a reverse boost creep condition at higher boost. So my point is, you might have thought you saved yourself alot by getting a bigger housing and not creeping at lower boost levels anymore, but at higher boost levels where the Evo 16g is designed to go, its now going to bleed off unless that wastegate solenoid was somehow changed.

hey i put it on my 16g and man did my creep go away.... i know everyone is talking about porting stock housings are better but the fact is that its steel so it wont crack, its fully ported everywhere... its got a nice design and it does have the 38mm wastegate...
i used to run off of the wastegate with no boost controller and my boost would creep from 10 all the way to 20 psi... now it holds strong through all gears and all the way to 7grand (as high as i rev my car)... man i could not describe how much this helped spoolup... dropped it down substantially... i can be in 3rd gear goin like 25mph taching 2500 and floor it and have full boost by like 2800rpm .... i plan to keep the small 16g for a while and my racecar is my street driven car so i like the early spool... it keeps me out of the high revs and saves them for racing... after suffering from late spoolup and boost creep for the last 4-5months, i am VERY pleased with this exhaust housing....
install problems such as that bastard sob snap ring and the part of the o2 sensor gasket you have to grind away are minimal in my opinion compared to the benifits i recieved from this housing

now i cant wait for the 650's and afpr to come in so i can install them with my 2g mas and intake then the boost gets cranked up

happy boostin

[DSMatMSU]

i wouldnt spend more than 20 dollars on a carbide bit to do some porting, which i allready own 3 of... my point is the all round benefits of this housing in my situation.... like talked about above... SPOOL UP TIME!!! broken bolts in my housing, 38 mm wastegate, did i mention how BIG this housing is

and if it does start to bleed off at higher boosts... ill upgrade the wastegate actuator... thats not exactly something hard to do....

its the new hotness man... i see your point, but you cant doubt the fact that this is a good upgrade...

 

[DSMSpyder99]

the bullseye housing is great (and heavy) i dont have any creep on my Profec-TypeS on my low or high setting 10PSI and 15PSI respectively. I would reccomend if you plan on keeping your 16G for a long time : the housing is made of steel so it well last longer, its bigger than a 7cm^2 housing, and its a 38mm flapper this will never creep

 

[DSMatMSU]

since you mentioned that about having problems with the stock WG... i amuzed myself and looked around a little, are there even actuator upgrades for our cars??

my roomate has an HKS on his sr20... but i havent had much luck looking around... allthough i did run across one that appeared to be 'universal' dunno how that works...

that was another reason why i got this housing... i plan on getting every last PSI i can out of this turbo... so ima keep it for awhile... i just got my 650's and AFC a few weeks ago.... and hopefully this motor i put together last summer wont shit a bearing or something on me...

That Bullseye tubine houing is a work of art. When I got my 50 trim from DSMspyder99 I almost did not want to install it cause it was nice just to look at!! BEEFY!! to the max. Check out the thick flanges! It's a very impressive pece of work and must be a great addition to a Mitsu comp housing. Mark

PS: My actuatoris from AGPTurbo and IT has held 20 psi so far as that is the most boost I have run up to now. Hoping for 22PSI on pump, 25 psi on race.

That's NOT an actuator upgrade. It's a flapper door upgrade. I've heard that the EVO3 16g actuator is stronger than the standard 14b/16g one, but I've yet to test it out. I'm in the same boat, we're running a 20g internally gated and it'll hold 27psi until about 6k then it falls off fast. A bigger WG hole isn't the answer. We need a stronger actuator. If the EVO3 actuator works, I'll be happy. If not, we'll be pulling off the turbine housing (it has a 34mm flapper) and putting a 7cm with the standard flapper on. As much as I'd love to try the Bullseye, I'm afraid it'd just make our problem worse

 

[DSMSpyder99]

you guys with the housing notice that you can adjust the flapper right no need for a adjustable actuator

 

[90blacktsiawd]

You said it help considerably with spool up time right, well what about top end? I have an evo 16g and a crazy case of boost creep. Ive been looking into the bullseye ex. housing and im glad to finally hear about someone with it that solved the same problem i have. So you made your reference about spool up in 3rd but over all when does it get fully spooled?

 

[16g-95gsx]

I dont get it though. You guys have yet to talk about any high boosting applications here with this turbo. Theres no mention of if this turbo holds the higher boost (20+) right up to redline with absolutely zero drop off. Like I said, low boost, thats fine, the larger flapper sure as hell will eliminate boost creep, but I just honestly think you guys are killing your hopes of ever running high boost and holding it. The theres guys on DSMlink who run SMALL 16g's at 23psi on pump gas right to redline with zero knock, its easily doable if the turbo is ported right, and thats all it takes to keep creep away on an Evo 3 16g, which even if you dont port yourself, costs FAR less than this housing does, hell FP only charges 95 dollars and you know they'd stand completely behind their porting. The turbine housing of the Evo 3 16g is not a bad turbine housing at all, and honestly I dont know why you'd think longevity of the turbo itself should even come into play, I ran my small 16g for damn near 8 years on my car, and it was fine right up to the day I replaced it with a FP green. Basically by getting this housing I feel that you guys are spending twice the amount that it would take to solve a problem, and in the process causing another problem shortly down the road, and I feel that no one in this thread is even acknowledging it, everyone is just thinking about the instantaneous effects, which really could have been had for half the price.

 

[DSMSpyder99]

porting the turbine housing has very little effect on boost creep. I got my EVO 16G ported from SBR, along with a ported 2G o2 housing, and a SBR manifold. Your telling me that all this should of gotten rid of boost creep right :laugh: The boost creep is due to the flapper door being too small and blows open because it cant keep the boost controlled. The MAIN REASON why i got the Bullseye is because i have heard cases of 34mm flapper doors still creeping on e16G. On the other hand, i have NEVER heard of a case of a 38mm flapper creeping on a 16G, 50Trim, 57 trim, or 60-1 trim.

 

[90blacktsiawd]

Amen brother. I have a ported evo3 16g with a 34mm flapper and it still creeps like a mother. Maybe i missed something in tread but y would changing the turbine housing affect the longevity of the turbos life? I'm looking at the bullseye housing for the same reason, I've never heard about the 38mm wastegate creeping. Not to mention its a higher flowing housing to begin with.

 

[DSMatMSU]

i do see you point, i plan on boosting something like 18 - 20 on pump and then i figure 25 would be the most ild feel comfortable with on race gas... but your not even speaking of the benefits of spool up time.... again, creep wasnt the only thing i took into consideration.... allthough it did spur the purchase... (not to mention the bolt in the housing)

this is my DD, gonna see a lot of autoX (yay for quick spool) and ill definately be hittin up the strip once or twice a season... maybe a little NFSU2...

and like i said before, BUY A NEW ACTUATOR!!! even if there isnt one that bolts right on, im sure it wouldnt be that hard to fab up a bracket to make a stronger actuator work...

You are a very ignorant person, Creep is NOT just caused by a damn flapper door, if you honestly believe that then please by all means get a 50mm internal flapper, its your turbo. The problem on Evo 16g's is the WASTEGATE ENTRANCE, not the flapper. If you look into the turbine housing inlet, you will see that there is quite a bit of metal covering the wastegate port. Port this away, so that there is a more direct route to the wastegate flapper and thats all it needs. 16psi is no problem even on 3" exhausts, and honestly if you have that large of an exhaust and still want to run less than 16psi, I dont think is the turbo for you anyway. Enjoy your modding process, cant wait to hear the thread down the road about how your Evo 16g now acts like a T25 at 5500rpms, bleeding off to a much lower boost than you want. Here's my favorite line of yours "The boost creep is due to the flapper door being too small and blows open because it cant keep the boost controlled" I think your marvelously intelligent comment pretty much summed up your ignorance on this issue.

As DSMatMSU says, if a new actuator were used this wouldnt be much of an issue as the solenoid would be strong enough to keep the wastegate shut at higher boost levels, but if that is replaced you are beginning to look at quite a bit of money spent, when all you needed in the first place was a simple porting job. I just really hate to see ignorance in this thread cause others to buy a housing they DO NOT NEED, and in addition loose their high boosting abilities.

 

[16g-95gsx]

Just so you can see just what I'm talking about, since you continue to insist that porting isnt the answer, here is an image.

You can see that the entrance into the wastegate passage is no longer perfectly covered up, it now has a much smoother entrance.
