upgrading turbos

[562DSMGST]

so i am trying to upgrade turbos on my 2g gst . i cureently have a garret t28 , now i been doing some research and i found that 16g max out at an average of 350hp. that was my first option but now i am actually looking into buying something better, i been looking around and did some research on the precision turbos, and i like what i found. the thing is whenever shopping for one they seem to speak to me in chinese, as an example. ( PRECISION T & E 3231E ENTRY LEVEL TURBOCHARGER ) i dont know what the "t" or the "e" mean or the "3231e" , if someone could educate me on what this means, and weather i would need a different exhaust manifold or other parts it would thanks for those who decide to help !

well to help you out a little better what is your goal for the car? and also certain turbos require customization are you looking for a more direct bolt on?

Are you looking for a Mitsubishi bolt-on housing? What are your goals?

I went from the stock t25 to the evoIII 16g. That was a really fun turbo to a point. It spooled really fast. Being fwd, I ran into issues with traction. I decided to put in an LSD and went with wider tires. My next upgrade went big! I am now finishing up my hx-40w setup. I needed a turbo that had more lag to help with traction. One of the best investments I have made was DSMLink.

Precision T&E is the company, PTE for short. The numbers/letters such as "3231e" are just the model number. It does translate into the specs of the turbo such as compressor/turbine wheel and housing sizes. But that's a bit advanced for someone just looking for a turbo upgrade. What you should be looking at is airflow (lb/min), spool time, and exhaust housing/wastegate type.

Airflow equals horsepower. A big 16g turbo has a maximum flow of around 37 lb/min. Rule of thumb is multiply lb/min by 10 for a rough estimate of horsepower at the crank. So 37x10= 370hp.

Spool time is a factor of how big the turbine/compressor wheels are and the size/design of the exhaust housing. Ball bearing also typically spools faster than journal bearing, but there are some journal bearing turbos (such as Holset) that will spool faster than a similar sized ball bearing turbo. It's best to research what others have experienced for spool time.

The turbine housing is kind of a big deal. The PTE turbo your talking about has a T3 flanged housing with no internal wastegate. That means you will need a T3 manifold with an external wastegate provision. For a quality manifold and wastegate, your talking hundreds if not thousands in price. You'll also need a custom O2 housing to work with the DSM downpipe. There are many options that have a DSM flanged housing, or can have one installed, so they can work with stock style manifolds and O2 housings. I would recommend this for someone looking for an upgrade from the T28. A 20g in a DSM flanged housing will make over 400hp, which is enough to scare people right out of the passenger seat.

I'm not sure if your aware of this, but I also have to mention is supporting mods. You need enough fuel to support more airflow. The stock fuel system can handle the T28 at 10psi, but not much more. For anything more you need a tuning system, larger injectors and pump, etc. You'll also need some traction mods for over 300-350hp in a FWD car, otherwise you'll spin through gears without going any faster. Turbo lag can help reduce wheel spin, but only to a certain point.

This^^

Going off your mod list, you're not fully using your current turbo. So upgrading to something larger is pointless.

Supporting mods are a mandatory requirement to upgrade the turbo. Maybe filling us in on your current mods and goals will help us answer your question better.

in response to what i want from the car is a street/strip car giving me an average of 350-400hp,
and yes in response to 2gmitsueclipse i heard a dsmlink is essential to getting the most out of a 4g63
in response to what supporting mods i have are:
greddy FMIC
apexi safc
evo III manifold
Blox manual boost controller
autometer boost & oil pressure gauge
hks bov
aeromotive fuel pressure regulator & fuel pump
greddy 3" straight pipe
injen intake
upgraded injectors(dont exactly know what are the specs, bought car with them)

i was also thinking of going through the trouble of making it AWD since i found some gsx transmissions for a descent price here socal , i just dont know if the transition is something that is worth the while and if the expenses are not insane .

yes the easier they bolt on the better.

if your only looking for that much power with an easier install setup with less modifacation go with the FP 68 HTA it has the capabilities your looking for and quick spool up. Forced Performance Turbochargers: FP 68HTA for DSM

get rid of that safc though its useless get DSMlink and also find out your injector size its always good to know what you have in your car.

EDIT** DSMlink isnt only essential for getting the most out of your 4g63 but for tuning and monitoring to make sure you engine is running right along with other monitoring device such as wideband, boost gauge, oil pressure gauge, temp gauge before just slapping on the turbo make sure everything maintinance wise is 100%

 

[562DSMGST]

everything you just said sounds right, i am hoping to purchase the DSMlink by mid january , hopefully i can get the hang of it and use it to it capabilities

are there any other turbos that fit into the same description of turbo i am looking for?

Go with the 20g if you want a bolt-on turbo. You will need the 16g install kit. Many venders sell them. Also check VFAQ for the install. This is assuming you take the advice for the added modifications. You will need:
Basic maintenance
the install kit
bigger fuel pump w/rewire
Larger injectors
AFPR
External wastegate on 20g (recommended)


Also, start building another motor to drop in when you pop the one you have.

sounds good, how long on average does it take before the motor "pop"?

 

[northernawd]

what exactly do you mean "pop"? And to use dsmlink your going to need some sort of wideband to monitor your air/fuel ratios.

 

[2gmitsueclipse]

My stock motor did not like much over 20psi. It was a matter of time. I had a built one ready to drop in.

i heard that , im going to do some research so i can buy exactly what i need
