I noticed this turbo listed on shearer's website the other day. I have not researched non MHI turbos all that much. But I know the "50 trim" in all it's variations is known fairly well as the "pump gas king" I am looking for 380whp out of my Evo III but if I can't get it then I was thinking this would be a good options since I HATE lag.


Does anyone have one of these or know when it hits the 25ish lb of boost area? It being BB I would think fairly quickly. If I could find a turbo that can realisticly be capible of producing 400whp on pump and spool under 4k I will be VERY happy, so long as it doesn't cost 2k .

I am more than likely re-enlisting in the army so just pondering what to do with the potential bonus, besides a engine rebuild .


I would do more research on this myself, but with limited free time being in Iraq, and just SOOOO many damn turbo's out there I thought maybe some turbo guru could help me out?




Thanks




P.S. I did run a search for the turbo, and found a few threads which I am in the middle of reading. But thought it wouldn't hurt to start another asking my questions. If the threads I found answer all my questions then I will delete this one.

with a 50 trim you will have more lag than say the Be316g. full spool your looking at around 3800k, but you will also get your power easier than with the 16g.

Be316g




From one guys thread I noticed he claimed his spooled by 3,800rpm.





Only a few questions then. How reliable is this turbo? I noticed a few comments concerning this. And do you need to restrict the oil flow from the head for this turbo?

I am concerned about the reliability side because that is half of my goal. A reliable 380-400whp car I can beat the snot out of and not have to worry. So if you have any other turbo suggestions that don't cost an arm and a leg, by all means seeing as I hardly know even all the turbo combo's out there.

I was also looking at the FP 18g and green, the green seemed like over kill and like it would be to laggy for me. And the 18g, I am just not sure about. Seems like it might be up to the task. And I bet would be more reliable. Not sure when it would reach full boost.


Maybe if I go into detail about how I plan to build my engine you could offer better advice. I am going to keep Mitsu 7.8:1 pistons, and on the bottom end the only things I was really looking to upgrade were to replace the bearings with ACL Tri metal ones, and SCAT rods, since I noticed they keep the oiling hole on them where as Eagle's do not.

For the top end I was planning on going with a Mitsu composite HG with A1 head studs, BC springs and Ti retainers, new valve stem seals, Evo exahsut valves since there sodium filled. with a fresh set of intake valves (stock) Still have not decided on cams but as of now I am still thinking Brian Crower 272's Although I would kind of rather have a 264/272 setup but it seems BC stopped selling 264's.

Otherwise just replace all worn parts I see with new.



I was thinking about removeing the balance shaft but not sure about it any more. Since the oil pressure shoots up and the only way I know to correct that is to port out one of the passages on the oil filter housing. And keep in mind I have never rebuilt an engine myself. This will be my first, however I will have my old man helping. (63yr old GM tech)

Just seems to me it may be better to just go with a Kevlar belt (like I already have on it) and leave it in place that do all of what is required to remove it.

 

[dSmgs-T]

big evoIII 16g haha, sorry.

to be honest im not sure about restricting the oil from the head, depends on the pressure.
and with any turbo theres always reliability issues, especially if you plan to beat on it all the time. i would say for the power you want to make this turbo is rated at around 460hp so you should be fine. also go externally gated!!

 

[RipperXX]

Already am baby!


I must be one of the few guys on this forum that is pimping a external tail waste gate on my MHI Evo III 16G. So you think this is about the best turbo for what I want to do?

 

[dSmgs-T]

i would say so, like you said their "pump gas kings"
i cant wait til i get mine on FINALLY!

 

[BrokenTsi]

If you HATE lag, get used to being SLOW. Lag is overrated. Please stop buying turbo's based on their spool time. Just downshift and floor it. I've never seen any turbo that was too 'laggy' to bear. Once you're spooled, you're banging through gears like a busa.

I mean c'mon, you dont launch your car at idle, and you sure dont start a race from a roll at 1200rpms.

FP green will not be laggy, btw. Its not even a big turbo. 400whp before 4k? Good luck.

In all honesty, if you dont want lag, buy a v8. Its not THAT bad as you think. A fully built engine for a little 50 trim is just a waste.

 

[secondnature]

If it was me i would go out, and get the 50 trim .Its a good turbo.I have the pte 5031e.Nothing wrong with it.Its been a while since i have drove the car seeing as its always broke down.But when i had it together i was only running 15psi because i just got the car together last year and i had to get it to are team Meet.So i slacked on putting the rest of my parts on.Thats why i had it set to 15psi.When i did get it together i took my friend for a ride and at 15psi she pulled.And that turbo isnt happy until like 20 + psi.It wasnt as laggy as i thought it was going to be.Now this time when i get the car running again ill have fp2 cams and ill be running about 20 + psi .I cant work right now because of a fracutured ankle so its going to be a while ,before shes running again.You`ll be happy with that turbo.As for restricting the oil from the head .You dont need to because the oil psi isnt as high as it would be if you ran right off the oil filter housing.You`ll be fine.When you remove the balance shafts ,the oil psi gos up .But you`ll still be fine running oil feed from the head.As for reliability .As "dSmgs-T" said.Deppends on how hard you run the car.For the most part unless you get metal in the turbo or something like that should be fine .Just take care of the car like you should and no problems .

Whats wrong with a 50 trim ??

 

[blcknspo0ln]

I agree. Now that I think it's safe to say that my built engine is more than what my 50 trim can handle, it was a great turbo, but will not be enough for what I need

I've noticed though, that my spool time has dramatically changed ever since I've gotten my 280's and JMF SMIM. Spool time was right under 4k for 22 psi and now I get full boost (26 psi) by 4500. Not so bad a sacrifice considering the solid airflow past 6k.

 

[RipperXX]

Well I wouldn't call my planned rebuild a "fully built" engine. But it will be over built for what I want. I want to do that because I want to be able to beat on it and not worry.

And sorry I am not into strictly drag racing, so lack of lag is important to me. More so since my goal is NOT a race car. I am simply trying to build this car to be IMO what I think mitsu should have. Hence I am trying to drop it's weight as tastefully as possible, and make it handle much better as well as pump up the power all while trying to maintain a factory/quality/unmolested image.


Although, that FMIC is pretty noticeable .


That being said, if I re-enlist in the army and get 20k to play with (should save it but whatever) then I may look at buying something else and go more extreme on the 1g.

So you do like the 50 trim? Also . If the 18g is that price i would think paying 100 more and you can get a 50trim .DEJON | Powerhouse

My car isnt a drag only car. Its a daily driver. It can do anything I want it to. My "fully built" engine consists of eagle/wiseco, sbr stage 5 head, comp101200's and a jm fab intake. My 3082r (3065 in a .82 t3 housing) hit full boost damn near instantly. My car is more or less full weight. Its all there.

Nothing wrong with a 50 trim, just dont buy it because you're afraid of lag. Sounds like you dont have much experience with turbos other then a 14b, but once you slap on a 50 trim on an engine that should be doing more, you WILL be buying a bigger one every year. Thats how I was. You'll want more. You'll soon realize that lag isnt that bad, and kids on the internet make a big deal out of something that isnt. You'll see.

I agree .Cant be scared to try it .You have to try it for yourself to see if you like it .Your hear to get peoples oppions.Oppions are like assholes everyone has one . .Get what you want to get .But again dont be scared to get something big as far as turbos go.

Well I mentioned the FP 18G because it seemed like a better fitting turbo for what ripper is asking for. I for one absolutely LOVE my 50 trim. To my pleasant surprise, I do believe I'm finally at the end of it's capacity, however. The damn thing just doesn't want to hold more than 26 psi with this baby mitsu housing on it. With the addition of methanol and some real tuning, the 50 trim is an instant spooling, hard hitting street turbo that does 400+awhp with the right mods and is MORE than streetable to even the biggest cry babies.

 

[RipperXX]

I wouldn't say I am afraid because of lag, more like I am "afraid" of spending money on a turbo I don't like.

And you may very well be right, the way I plan to build the engine it could take plenty more. But if the PTE SCM 5031RE spools at 3,800rpm and can make 450ish whp. Then it should exceed my goals. I only set out to have a good handling flat 12 to high 11 sec 1ga that looked good inside and out, and was reliable.

And after fresh paint, suspension, brake upgrades, rebuilt tranny and freshened interior. I am almost there.


Thanks for all your opinions though. I am just not one of those guys that wants 600hp....at least not yet anyway. If I reach my goal, and I get dusted by some supercharged vett or something then no doubt I will want more power. So it is something to consider. I have plenty of time to ponder on it though since I wont be home from Iraq for another o something like 390ish days. I just wanted to know what you guys thought about this BB 50trim. Everything I have heard so far about it sounds pretty good.

Only thing I noticed is that I would want to replace my Evo III manifold with an FP so I don't have clearance issues.

 

[BrokenTsi]

Do you want a mitsu bolt on style turbo?

I dunno, to me, the 50 trim is the next 16g. I remember back in the day, when we didnt have a lot of options for turbos, 16g was the turbo to have. I went 13.2 @ 105 on my 14b with not many other mods. I went 12.3 on an rs49 (50 trim). I could have gone faster, but I only ran it once.

If you want my opinion on turbos, the gt3082r (t3 .82ar) spools real fast, and makes sick pump gas power. I ran that turbo at 26-28psi on pump ALL the time. I made 500whp easily on pump. The top end on that turbo is sick, and its so streetable its not even funny. I know you would absolutely love it. When you want to run 10's, you can, or you can run 11's on it without even trying. It will accomplish your goals easily. Little more pricey, but well worth it IMO.

 

[RipperXX]

I will take a look at it, thanks.



Searched and couldn't find much on the gt3082r. Just two threads, neather of which was very helpfull. Which is ok really since I only had a stock rebuild done on my trans, I don't think it or my 3 bolt rear end would like 500hp very much .

 

[BrokenTsi]

3 bolt rear doesnt like anything at any hp level. 3082r is the same thing as an fp3065, just in a larger t3 housing. Search fp3065, and you'll get answers.

 

[RipperXX]

Thanks!


in that case I am surprised it has not already gone. I know even untuned before it blew the HG (still hoping it's the HG and not a cyl) It was close to 300hp. Lack of tune had nothing to do with the HG btw.


Now if I can figure out a way to just get the engine rebuilt while I am thousands of miles away

 

[BrokenTsi]

I know how it is. My car sat for 10 months while I was at Ft. Benning. I just got back home last month, and my car is in pieces.

 

[RipperXX]

Well I am stationed in OK, my car is in GA, and I am deployed to Iraq

 

[1992awdlaser]

I agree with everything brokentsi has said. And his car was a beast on the street with pump gas. I don't think I ever got a chance to be in it with race gas.

I have a sbr g-50 on my car. I am going to try to make it run 10's on stock bottom end and just boost. I think it can be done, but this will be hard to do. I woulddeffinately get a bigger turbo. I have been in brokentsi's car with the 3082r on it, an rx7 with a t78 on it, a evo IX with a 35r on it, and probably a few others with big turbos. None of them felt too laggy to me.
