50 trim?

[My96AWD]

i have a awd 2g. my turbo went out so i was looking for a bolt on 50 trim. pte has one the choices are .48 or .63 a/r. and 76 trim or 69 trim. i was thinking of the the .63 a/r for more top end, but i have no idea about the 76 trim and 69 trim. in the end i want to have atleast low 12 sec runs.

also can i drive it with the 50 trim at the lowest boost and stock everything else (other then upper and lower ic pipes, ported mani, ported o2, and turboback, and of corse an intake) till i get some more money to get the supporting mods. i know i should have all of the supporting mods done before i put it on but i don't want to buy another turbo.

Buy the supporting mods first, and then buy a bigger turbo.

You should buy the supporting mods first however yes you can drive with that turbo and fully stock everything else, though I would say at least have a fuel pump first as it will make more HP at 10psi than the T25 does.

The trims on the turbo have different numbers but are basically the same as what your used to.

.48 A/R is smaller and will result in faster spool up times but will limit top end. With that said, guys have made over 400whp on a .48

.63 A/R is larger and will flow more exhaust. Many say going to a larger A/R is better than going to a larger exhaust wheel (say .63 stage 1 vs .48 stage 3) because of spool vs. flow

PTE 69 Trim is the exhaust wheel. Thats like a stage 1 wheel. smaller great for spool works in both .48 and .63

PTE 76 Trim, is also an exhaust wheel. It's like a stage 3 wheels, larger for more flow and higher top end.

Typically a 50trim guys buy is .63 stage 3 (or .63, 76 Trim) which is a great street turbo. With 2.0L of displacement (which you already have) and good tuning you will spool that up no problems at all. If your worried about street spool get the .48 and 67 trim. It's gonna spool up a lot faster and will still pull hardcore on the top end compared to what your used to. Lets say you get to a 12.0, well the .63 with 76 Trim may go 2/10ths faster and 2-3mph faster because of more exhaust flow.

Some may argue that which is ok, it all depends on your setup. In theory however a larger A/R in a drag racing application should go faster. Anything setup properly will work extremly well however, this is reality.

660cc injectors, SAFC, 255lph pump are a must on this turbo. I would also get an AFPR with that. You will also need a FMIC and intercooler piping and BOV to go along with that. After this poing a full 3" exhaust will also be needed. Keep in mind the parts that are required when supporting a largeish turbo like a 50trim.

The *bolt-on* PTE mitsu sport compact turbos are offered in one A/R size, which is neither .63 or .48.

This is correct. There is only one turbine housing. I can't think of it either......

ON the wheels I don't think you will see a huge difference betweent he two. If you plan on getting the most out of the turbo get the .76. I love my scm50.

The SCM units are great. Make big power, and spool quite fast. The part about the SCM units only coming in one A/R is not true. The bolt on SCM 50 only does come in the .48 A/R, but from the SCM60 and above they offer the .48 and the .63.

My scm61 won't hit 20 psi till 5000 rpm even ... all depends on which one you go with.

Yes, you can bolt up the larger turbo and keep the boost down until you get the fuel mods. I once ran a car on 8 lb boost with all stock accesories for several months to break in a new motor and because I wanted to pass DEQ before I modded it further.

hey JZ 97 SS 1500 not to go off topic but your camaro 97 SS #1500 383 ProTurbo SFT PTE-88
is sick do u have any dyno numbers and 1/4 mile numbers from that beast and do u drive that thing around town it must really put u back in your seat thank bro

I was told that 190 fuel pumps that are rewired would work with a 50 trim?

based on the feed back we have gotten from customers who have purchased the SCM turbos is that the .69 wheel does spool about 200 RPM's (on average, some higher some lower) quicker.

A 50 can make over 450 whp, fuel is your friend. Go bigger, it'll save you money in the long run.

 

[bigjangin]

get a 255lph pump or a supra pump. I had a rewired 190 in the car and to sum it up now I have a rewired 255.

 

[My96AWD]

well eventually im going to get a fmic 880 inj dsmlink (i have a 95) 255 hp rewired and a afpr. but i dont have the money to get all that right now and my turbos blowing smoke and chewing the sides. so i stopped driving it. now its been over a month, and i want to start driving it again. gas is killing me right now in my firebird. its a 1g motor and a 14b.

 

[prostreetdsmx1]

you know personallty i would recommend you find yourself a used stock turbo for a few hundred bucks and spend the other money you would have spent and get something like injectors and a pump or what ever combo you want to go with. Get started in the process and once are ready you can do it right the first time.

Best of luck with the car.

 

[Knuckles2.0]

dsmlink.... i wish that 1g version would come out... heard alot about it a couple months ago.. any one heard any thing new... i'm also all set for the "pump gas king" i'm considering the agp rs49 or the rs 52 its on sale right now ...

 

[My96AWD]

anyone heard of http://www.straightlinespecialties.com/dsm/turbos.htm? pte bolt on 50 trim internal gate for 850.

 

[JZ 97 SS 1500]

My96AWD, I have them for $840.


91gstman, the car is almost done. The car under full boost should be close to 1000rwhp. This is just a temporary setup to play with for a while. I will be getting serious with the car very soon with Twin T70's. The car looks bone stock, and has all the factory equipment still (A/C, leather, CD, Power everything..etc). You can see the car here....

does it have the cut housing or no? i want to run a dump.

 

[91gstman]

thanks jose thats really impressive

 

[prostreetdsmx1]

when you want to run an open dump you should get it with the divider intact orelse you will be running open wastegate all day long. and it will be LOUD.

i know i was asking if he could get the uncut one.

 

[prostreetdsmx1]

i know i was asking if he could get the uncut one.

i remember i installed one with no divider that was running on a VPE dump O2 and the guys was like "no its ok, ill be ok" well Virginia State Troopers felt a different way. he got busted the next day and had to uninstall it. :laugh: some people just dont listen.

 

[VBGSX]

There is really no reason to get the cut version in the first place.
Myself and others have the uncut divider and aren't seeing any creep at all.
It's all in the porting of the O2 housing.
I've had mine at 15-16psi and it's held rock solid. I don't run that now but it's a nice place to set it if I want to drop my car off at the dealership.

And about the 190 pump.
Yes it will work fine. It's very under rated.
I'm currently running 20psi on it now(rewired). You can see my mods in my profile. I'm just waiting to turn it up more once the FMIC gets here.

There are others that are running 23-25psi on pump gas with the 190

It's all up to you.
