Turbo help

[Jordan_40]

I don't want to sound like a noob here but I'm very puzzled. I bought a super 20g (gsp) and I went to put it on yesterday and it doesn't bolt up to my header. I need to know what header to get, one for a t3 setup or what? Thanks in advanced

Chances are you have a 10cm2 turbine housing - T3 style manifold is needed.

Well I'm trying to post a picture but I can't figure it out

I hope gsp does not mean godspeed 20g.Cause that is a noob mistake..

Yup, T3 flange but read this thread before you decide on installing it or not.

Ya I wouldn't do it unless you want to pull it back off in 2k miles and have to buy a quality unit. Just speaking from my personal experiences.

Although since you already bought it, you should pm jusmx141. If there is no damage to the unit he may be able to rebuild it with quality parts. And he is located in pa so you might just be in it a road trip and the fees for the rebuild.

Yeah I'll just buy a new one... I figured something was up when I got an 18g and a 20g turbo for 300 bucks... I honestly just bought them to re sell but my turbo is starting to get a little shaft play in it so I was just going to put it on, time it and hope for the best. But now I don't think that's such a good idea

 

[Dsmkauai]

Not saying to use the turbo but you can use a dsm flange to t3 adapter plate. It goes in between the manifold and tubrine housing. I used one with my hrc s16g and had no issues at all with it just a FYI! I even have a extra one that I got with my talon, so they are widely used from what I can tell. But the best would be a t3 mani if you got $7-900 to shell out!

 

[Jordan_40]

Ok well now finding that this turbo is a china junk, anyone care to steer me in a right direction of a turbo that I can push 25-30 psi through that's not gonna kill my wallet to buy?

 

[tuby]

Just keep looking on the classifieds for MHI 16G or a real MHI 20G. You might be able to find a used hx35 for a descent price. It's just not a bolt on. Good Luck man!

 

[athlete3344]

You can push 20-30 pounds through a variety of turbos. What kind of HP were you trying to put down? Were you looking for a 20g or equivalent?

Rebuilt is always an option, expect to pay 500-700 depending on the size. Do you have an urgency to get the car running or can you get it running and wait for a deal on a new turbo?

 

[Jordan_40]

Well it still runs good now, but the shaft play is worrying me so I'm able to wait but I'm just trying to figure out what to order. My hp numbers that I wanna reach are like 350-375 ish. It's my DD so I don't wanna go crazy but I wanna be able to play.

 

[athlete3344]

A 20g will get you there no problem. Best bet is a used one if you want to get it sooner rather than later. I ordered one from FP about a month ago and its still on backorder - but Im nowhere near finished building the motor.

An option would be just to pick up a 14b in the mean time.


Just as a note, in order to tune a 20g you will need supporting fuel injectors, pump, regulator, dsmlink, supporting instruments for tuning, etc. You mention you cant spend a bunch, but all together it will be a large chunk.

 

[gsxbro13]

In my opinion there are better turbos out there than a 20g. I think the turbo has quite a bit of lag for what your getting. I would personally go with a hx35 if your looking for that PSI and alot of power. The HX35 is bigger than the 20g and i feel is a much better turbo performance wise and durability wise as well.

Look into the Evo 3 16g as well. It wont push that PSI effectively but it spools great and is a great turbo that could be used decently but make alot of power with the correct supporting mods. The 50 trim is a bit bigger than the evo 3 16g and also a excellent turbo as well. These turbos are the best streetable turbos for being on a budget and also would be highly capable with that HP goal in mind.

Sometimes its not all about how big the turbo is and how hard its being pushed, having the correct supporting mods done and a good tune will be more beneficial in the long run. Just my 2 cents

 

[Jordan_40]

I have about roughly 2k to put into my turbo with supporting mods, I plan to get ECMlink 800 to 1000cc injectors and a 340 fuel pump. I think that would be plenty to not starve it or am I wrong there?

 

[gsxbro13]

2k is a decent budget depending on the mods you are already have done. A list of the mods you already have done would better determine whether 2k will be enough or not.

For any street turbo a 255 walbro with AFPR and 800 injectors would be more than enough for your average street car on pump gas. I would actaully not be interested in a 20g with only a 350HP goal in mind. A smaller turbo like the 50trim and evo 3 16g can produce that and much more with a better spool time.

For a street car i love the faster spooling turbo that way i dont have to run higher RPM's to get full boost. If you are keeping your HP goals under 400 I would definately do more research on the the 2 turbo i suggested. They are more than capable of that kinda HP and youll keep better spool time around 3100-3200 with the evo 3 16g. I am not telling to change your mind on your turbo you want but what makes you stuck on the 20g over other turbos?

 

[McDizle]

You could also run E85 for the higher boost? Just an option. Like gsxbro said I'd consider going with an MHI 16G for the quicker spool! If you have E85 in your area I'd go that route. I'm planning to. You'll need bigger injectors but the wally 255 should be fine for your power goal

 

[athlete3344]

I bought my 20g over a 16g mainly because of this thread;

http://www.dsmtuners.com/forums/turbo-system-tech/436974-why-not-tdoh5-20g-street-dd.html

The 20g just seems like more fun.

Also, you can probably get away with a walbro 255, afpr, and 850cc injectors for fuel.

 

[Jordan_40]

Well my original plan was to go with a big 16g then I got word of this guy having the 20g I got and he was local so I figured if snatch it up and resell, make a couple bucks. But now mines getting a little shaft play so I need to do something before to long.

Hey to the poster, you can just put an Mhi turbine housing on that 20g you have and it will bolt on like stock. That is a lot cheaper and less complicated than switching to a t3 manifold. Just port the one you have if you need more performance

Have you ever had a 20g? The spool is about the same as a 16g. So I don't know what you are talking about. A 20g is about the fastest spooling turbo you'll find to get close to or eclipse 400hp. As far a durability, at pump gas boost levels a well oiled 20g will last forever basically and with the newer thristplates in rebuild kits they will go forever at high boost levels too. Mhi turbos are about as durable as you'll find.

The only problem is the 20g the OP has is a garbage product from china.

 

[LandSpeed-DSM]

Having had a 14B, S16G and Greddy 18G in the past.. I would opt to skip to a newer, larger turbo than the 20G. Especially if it's mated to a TD05H turbine wheel. More than likely if it's GSP, it's TD06H.

Save up for an Open T3 setup and something in the neighborhood of a 3076R or HY35. This will give you room to grow when you inevitably get bored.

They are reliable, spool quickly, and are very potent on pump gas.

 

[gsxbro13]

Why change the turbine housing on a 20g if it will change the whole turbo? I completely diagree with you and that to me makes no sense at all. the 20g i have drove with in the past felt laggy at 19psi and didnt finish spool till basically 3400. 350HP is not alot of HP really and a smaller turbo will spool around 28000 or 2900 and finish at 3200 which is before the 20g. Maybe the 20g i drove around was set up wrong or had other problems? However i am going off my opinion on the turbo when i drove it. Honestly my old evo 3 16g was a big improvement over the 20g.

Smaller turbos are way more fun for a DD or street car over a bigger turbo. The 20g with obviously reach what the OP wants however i feel there are many better turbos than the 20g.
