PTE SCM61 or AGP RS60T

[djsven]

Hi,

I have a hard time deciding which one to get. My goals for this year, is to get myself into low 12sec (12.2) and around 400-450whp. But I am still running stock engine, transmission and axles. So, I can't run to much boost. Say max about 20 street with pump gas, 25 track with race gas. I am thinking to get better axles later on this year, depending on the funds. I am in process of building my 4g64 and this will be ready for next year season accomplished with a shep race transmission. Then I want to go all out with the same turbo (PTE SCM61 or AGP RS60T). What would you decide and why? Please only reasonable anwsers and no bashing! I also know about other turbo's like FP3065, but they are out of my price range for now. These 2 are my choices.
Other question: what have you made (HP) and run (et times) with these turbo's?
Thanks,

Sven

SMC61 will put down more power. And will put your car in the 11's low 12's with a bad driver at 20 psi. You may blown your 2g motor if its not tune well. Or tune too well and more 400-450 at the wheels at 20psi.

SMC61 w/ 38mm internal wastegate & $30 gasket set for a dirrect bolt on @ $926 shipped gets two thubs up from me.

just rember to buy the non-turbo waterpipe and thermistat housing. the SMC61's oil cooled. so buying a used air/air 91 oil cooler would be ideal, and just tap a feed line to the turbo!

SMC61 will put down more power.

I'd like to hear why you think this.

 

[talonpower]

don't quote me on this but I believe the SCM61 has a larger compressor wheel ....

 

[dsm4lifebeoch]

scm61 does have a bigger compressor wheel but only flows 10% more air then the 60 compressor wheel.
i voted for rs60t for the price you cant beat it.

The SCM61 also comes with the stage 5 turbine wheel by default, where the RS60T has the stage 3(according PTE's and AGP's websites).

Doh! I missed that the first time around. My eyes saw the "T3.." and kept moving.

The Rs60T comes w/ a no questions asked warranty!

For one its a big trim wheel. And I have a 60trim turbo the max output is 600 scm61 is 680.

 

[goofynick6]

Have you considered the AGP61? It's just like the sc61, dunno of it comes with a Mitsu housing, but sure Ben or Kevin could get it for you.

Actually the scm61 is only rated at 630. I ordered a scm 61 but was mistakenly sent the scm 52 with a stage 5 turbine. I just got it yesterday and I have decided to keep it instead of sending it back because I probably wont run boost levels high enough to really see a difference. Also, pte is out of stock on the 61 so I would have to wait even longer.

In my experience, goals usually change every year and its always for a faster time.
I would go with the SCM61 and hold on.

Hi,

I have to thank everyone for their replies. But you aren't helping, . At this point it is a 50-50.
The scm61 will make more power, but is a little more expensive and might have a later spool up.
While the RS60T will almost flow as much (60lbs/min compared to 65lbs/min), is cheaper and has a great warranty.

My final thought, Do I need to spent the extra money for a bigger turbo (more powerfull) that might get me to my final goals? But might not see the full potential of it, because when I am ready (1-3 years from now) for the full power to reach my final goal, I might want something bigger, better, faster, maybe full ball bearing? So, I might not reach the scm61's max power. Do I need to save the extra few hundred and put it towards something else or just go for it and get the SCM61?

Are there people running the SCM61 on a stock block and transmission? If so, what boost levels are you at with pump and race gas?
Thanks guys,

Sven

SCM61 isn't a turbo for stock motors or trannies. It will break your trannies if you are using it right. If you are talking about in one to three years before you finish your setup. Go with the rs60. Little more power than a 50 trim and not too much laggy for a stock 6 bolt. I'm going to be running my 2.3L and a 60 trim. Est full boost at 3300 at least at 20 psi. I ran a 60 trim before this set and full boost at 3500. These are huge turbo's and it all depends on what your goal is. A smaller turbo may fit your goal better. Call and talk to some vendors for more support.

 

[Mindslayer]

Check their site regarding pricing.

The Rs60T comes w/ a no questions asked warranty!

Thats only because they have the worst quality controls EVER and plenty of their turbos grenade.

I just got my RS60T.It is not a 60 trim. The 60 trim has a set of 6 curved blades, the 60-1 has a set of 7 straight blades. It has a 60-1 wheel that flows about 7lbs. more than a 60 trim and much more airflow at lower PSI.(per Dave at Bullseye Power) It has a completely different wheel than a 60 trim. It also has that beautiful Bullseye turbine housing. It is one beefy turbine with nearly a 3/4" turbo to exhaust manifold flange and over a 1/2" turbo to 02 gousing. Since I already had the oil lines from my RS49 I only had to spend $799. for it as I went for the internal 38mm wastegate which worked well on the RS40-50 trim I had. From the specs it probably spools much quicker than the PTE61 but that is only opinion, not fact. It's not simply the amount of possible flow but how quickly it spools. The compressor wheel has an inducer sized at 2.32" and a 3" exducer. Can't find the sizes of the stage 3 turbine wheel. Whatever way you go I suggest the AGP oil lines as they are also very beefy!

Hi,

Thank you all for your replies. I decided to go with the RS60T. I order the complete package with oil feed and drain lines and internal waste gate. I will try to post another thread about the installation and performance of this turbo. Thanks again!

Sven will you install the RS60T asap and drive the car? I ask because I have that turbo here on my living room floor, just got the 02 housing bolted to it. Too much snow and salt here so I will not get to drive my car until mid April. The actuator for the iternal gate is a bit awkward and you probably will want to bend the bracket that attaches it to the 02 housing as it has too much of an angle on the actuator arm. You'll see when you get it, no biggie. I am going to bend mine today. The bracket attaches to the 02 bolt arcoss from the 02 sensor. I did find the specs on the turbine wheel. They are 2.23" and 2.56". Bullseye will not release the a/r of their housing but just say it is between a .48 and a .63. The smaller size helps spool it quicker and there will be plenty of topend as I had the same housing on my RS49-50 trim. Interested in your mods, I'll check out the car's info. Mark

 

[sweet97]

What injectors are you going to run? I have 650's leftfrom my 50 trim and will go as far as they take me and then go with either 720's or 750's. Mark

 

[1SloColt]

SCM61 isn't a turbo for stock motors or trannies. It will break your trannies if you are using it right.

Turbos do not break trannies or destroy motors, people break trannies and blow motors.

 

[aero_sallee]

When you make enough torque to rip the teeth off 3rd gear, then the turbo will break the tranny.

 

[djsven]

Hi,

I will bolt it on, but there is snow here too. And I haven't gotten everything yet to run my car. At this point I have 750cc injectors. I don't know when I will be ready to run the turbo. But I will try to keep you updated.
Thanks,


Sven
