Which Turbo Should I Get [merged] What Turbo

[Ludachris]

Which turbo will be sufficient for consistent 11 second times? I've recently decided on a big 16g, but will that be big enough to run 11s with supporting mods and decent tuning? Remember, this is for a budget street car, so any one purchase over $1k is tough. A big 16g will run about $700-900, which is about $300-400 less than the larger alternatives.

Of course, I'll need lots of practice to run these times, but, I just want to make sure that it's possible before the money is spent.

A BB 50 isn't necessary for the times you want.

You could always just go with a conventional PTE 50 trim, or the slowboy G50, or even
G57. From Slowboy, it'll be around 1k, pending if you go internal or external wastegate.

But, just to throw it out there. An EVO III 16G can also get you the times you want.

I am really double thinking the EVO III 16g, there are realitively cheap and will require much less to get it on my car and running. I just have been stuck with 13's and I DO NOT want to run 13's again!

I'm pretty sure you know this, but it take more than a choice of turbo to decide what times you'll run.

 

[szewczyd]

Well yes I do, most of it is driver and tunning. But I don't want to get an on the edge turbo such as the 16g where if I hit low 12's I will be really pushing it. I am going to look further into the PTE 50 trims since I have heard how great they are on pump gas and as street turbos.

Is a 50 trim even worth running on an internal wastegate cause I know unless you get the 34 mm flapper for the 16gs you will have boost creep.

 

[GSntncT]

Well, my 50 trim is internally gate. When I was running 12 psi, it crept up to 13-14 before going back to 12. Now that I'm at 18, it goes up to 19-20 before going back to 18........

So for me all and all.....boost creep is no issue to me.

 

[toecutter]

Forced performance is having a small sale, since my turbo is blown i was in the market.

Which would be better to go with evo316g, 18g or sbr 20g?

I have friend with 18g's and 16g's there pretty happy with them, but i cant decide.

so any imput would help....thanks

 

[toecutter]

Oh I forgot to say, im running mods that would most likely support 16g and 18g but I'm not sure about the 20g

 

[No_Skillz]

Go big or go home.

But in all reality, what are you looking to get out of the car and what makes you unsure? I find that most of the time when people ask questions like this they've already made up their mind and just post for... I don't know why. So tell us what kind of goals you have for the car, what characteristics of the 3 turbos attracts you, and what repels you, and we will answer you seriously.

 

[toecutter]

Well i wanted to get close to 350awhp or so and run high high 11's or low 12's.

I havent made a choice at all yet, i wanted to get some feedback before a throw a chunk of money into something...

 

[toecutter]

I would also like to keep the mostly stock look, factory housing and all.

 

[No_Skillz]

350awhp is easily attainable with the 20G. Look into the SBR Bastard 20G... works off 16G compressor housing.

Keep in mind that to seriously tune this turbo to it's max potential, you will probably have to change your 190 to a 255 + fpr, get bigger injectors, and get a standalone tuning sytem. I see you already have an e-prom so this is not a big problem if you know how to use it. As far as supporting mods go, a 20G is not that big of a step up from what you have now.

350 is more of a stretch with a EIII16G, plus you will have to have highly extensive supporting mods to get it near there.

I don't know much about the 18G so I can't give you much input there, but if its performance bridges the 16G and the 20G, it should be possible.

 

[Ultimatedsm]

well for the EVOIII you need 650 cc injectors and you can get away with those on the 18G, however, 20g, I recommend 720cc or 750 cc injectors with the walbro 255LPH and some kind of AFPR. CLutch, intercooler (Supporting mods) you should get done before you slap on this turbo.

 

[seahorse]

hey i would go with a 20g its a great turbo ..i went 11.7 with it 3 years ago with only 550cc injectors 20 psi stock intake super side mount hacked 1st gen mas afc and stock ecu

 

[Deepsixer]

We have the same car bro. 1990 GSX and I've been thorugh all the turbos you're considering with the exception of the 18G. The 16G got tired real fast after about 2months of my desire for more power, plus, after @ 6000 rpm it felt like that was all she had. I currently have the Hahnracecraft Super 20G kit that has an internal wasgate, running 660 injectors and HKS 272/272 cams on race gas at 21psi. No boost creep whatsoever, and I can honestly say it's by far the most efficient turbo I've ever had. You're gonna sh*t yourself when you get on it with this setup because the power you're going to feel is sssoooooo strong, and keeps going all the way through 75k rpm. The top end is insane with these cams and that turbo!!! I don't know how much your budget is, but I would defintely recommend a front mount and some cooling fans if you want this setup. The ports on the 1G head are bigger than the other generations so you already have an advantage. Go with the 20G from Hahn. I have no experience with SBR so I can't speak for their turbos.

Ok so it doesn't get much more of a newbie question then this and I am thinking it is the 14b but I thought they didn't have the secondary fins on them. I looked at all the ebay ones and they didn't have the secondary fins but this one does. Is this the 13b? I opened mine up and this is what I found.

 

[JBDdsmer610]

That looks like a 13g they came on the 1g Auto.

 

[Andrew7DG]

that doesn't make much sence because it is on a manual transmission car

 

[JBDdsmer610]

is the car 5 speed or A/T

 

[Andrew7DG]

The car is a five speed!!! I feel like i have been cheated out of my 14b

this is a 90 car and the first year of production however i still thought they got the 14b!
The car is a five speed and always has been a five speed. As far as I know this is the origional turbo. I don't think the origional owner would put in a 13b in place of a 14b. This is just weird.
I should just go back to mitsubishi and demand for my 14b turbo
however they would just probably laugh at me

So next i should just save my money and just wait till I have enough for my 16b evoIII

 

[urcnjoe]

More than likely at some point the old owner did a JDM swap of some kind. They can come with any turbo as small as the 13g which you got, up to the 16g. You probably have the 450 blue top injectors instead of the automatic 390's. There seems to be a few motors like yours around and more than likely it was a swap or a really cheap fix for a blown turbo. If my memory serves me right I believe the 4g63 with 450 injectors and the 13g turbo came in the vr4's. Not sure what year. Others chime in if I'm wrong. Also it would have the cyclone Intake but most did not use it for the swap and a red valve cover. Hope this clears things up a bit, but you still have the 13g problem. At least it has balls until 60 mph.

 

[brute]

And then there's the highly sought after JDM vr4 motors that came with the yellow top injectors and a big 16g... I think the injectors were like 510's or maybe 550's.

 

[Andrew7DG]

Well it doesn't appear to be a swap. I will check to see if it has the 450 injectors tomarrow. I am hoping that they didn't put in an engine from an auto in the car. It doesn't have the red top on there or the cyclone. It just could have been a cheep fix.

 

[dsmaniac]

My brother has an 02' camaro with a cold air kit and exhaust. It has around 350 hp. He doesn't think a dsm car can out run it for cheaper than he paid for his car. He paid 18,000 for it. I told him he was crazy but he still doesn't believe me. please post so I can prove him wrong! Please tell me what turbo setup is best for outrunning him.

 

[prplhz96]

Tell him I have about $4,000.00 into my car(including the purchase price of the car), and I will look forward to running him at the track any day. A 14b with supporting mods will do some major damage at the track against alot of V8's. I am speaking from an AWD point of view BTW. Once you go with a bigger setup than a 14b, the win only gets longer and longer.

 

[spoolup]

There is a important triangle to maintian with DSMs as well. it the fast-cheap-reliable triangle, choose 2.

That being said, I know with the right knowledge person you cna get a car to whoop ass on his lightly modded Z28, without breaking the budget.

a good 50-60 trim is more than enough to accomplish your goal. Dont forget supporting mods.

PS a local here turned a $500 project into a tin can, thru on a few parts from the trader, did his own wrenching and ran 11.6x at RMR (4200 ft elevation). He had about $3000 including the car/ registration/ license fees into the thing. After eating countless sport cars he really shined the $3000 price tag off.
