Help me decide to stay or upgrade
 

I have the oppurtunity to trade my PTE SCM 5031RE for a PTE SCM 6152E .The things to consider here is that the 50 trim is ball bearing and the 61 is not. The 61 has 1k miles and the 50 has way more then that. I am an auto so the ball bearing was nice. I am still on the stock bottom end and really dont want to build it up for awhile. I have no problem with the 50 trim and love the power it has.

What are your ultimate goals? If you don't mind not having an assload of top end power, stay with the 50. I prefer a turbo that spools at a decent enough rpm to make it fun on the street without breaking too many laws, so I voted for the 50.

Re: Help me decide to stay or upgrade
 

Sounds like you're really happy with your current setup. I'd go with the BB 50.

Re: Help me decide to stay or upgrade
 

I do like the 50 an i wouldnt mind keeping it and putting nitrous back in for that little extra power. But hey who dosnt like a bigger turbo. But havnt i heard a bunch of talk about the pte journal bearings not being so hot but their BB models are better, thoughts?

Re: Help me decide to stay or upgrade
 

Isn't that one of swanny's old BB 50 trims?

I was seeing 20psi at 4200rpm with my scm6169. It is quite laggy but fun as hell once it gets going, but I have similar views to kevin, I like something that you can use on the street.

If you don't mind using nitrous, then I would say to keep the fiddy.

Re: Help me decide to stay or upgrade
 

My vote went for the 50 trim. As mutch as I love my 61 Ive been thinking alot lately that a 50 trim would be a great street turbo.

With the auto the 61 might be a good setup too since you wont have high RPM shifting problems and the turbo will stay spooled between shifts. you could always keep the Nitrous to spool the 61 sooner on the auto.

Re: Help me decide to stay or upgrade
 

I say keep the 50-trim. The center section is better and you have more usable power on the street. As far as building the motor, if you have a 6-bolt I wouldn't consider that an issue :D IMHO if you have a setup and you're happy with it, leave it. It's summer! Keep the car on the road, drive it, have fun, etc :) Have you looked into how to get more out of your 50-trim? E85 or alky injection? Bigger cams, tuning, SMIM, etc?

Re: Help me decide to stay or upgrade
 

HAHA i got cams, smim, e85, double pump, dsmlink, i think the highest ive ran is 28psi. I sold the nitrous but my brother has a kit to throw in if i want it back

ya its swannys old turbo, still kickin with no play in the shaft

Re: Help me decide to stay or upgrade
 

Have u ever dynoed it?
You should be making some damn good power with it, I wish I would of had money to buy one of those turbos.
If u ever want to sell it, let me know.
But to be honest i voted keep it, because it seems to be the best street turbo out there, responsive enough for everyday/practical use, but powerful enough to be stupid.

Re: Help me decide to stay or upgrade
 

no dyno. the "dsmlink dyno" haha was telling me about 370whp, but we know how accurate that is

Re: Help me decide to stay or upgrade
 

post some logs, oh u cant, maybe pm or something

Re: Help me decide to stay or upgrade
 

Keep the 50. PTE journal=fail for what I have experienced.

Re: Help me decide to stay or upgrade
 

Run some more boost, I hit 35psi with my evo 3 16g, my airflow logs register over 50lbs of air a minute:sport017:

Re: Help me decide to stay or upgrade
 

More boost might not mean more power. I say hit the rollers and get a professional tune. Shane can do some amazing things!

Re: Help me decide to stay or upgrade
 

Uh, 61 if its a straight trade. Jus do your mods accordingly and get a higher stall and it will haul. Its not like you're putting a 67 on your car. Go bigger or go home. Lag is overrated.

Re: Help me decide to stay or upgrade
 

Meh.

Re: Help me decide to stay or upgrade
 

Haha good to see! Those BB 50 trims have seen a licken and kept ticken no questions asked.

Re: Help me decide to stay or upgrade
 

I vote stick with the 50 trim.

Re: Help me decide to stay or upgrade
 

To be fair the powerband on larger turbos are more useful in drag racing applications/street applications where u are constantly in the high RPMs

Re: Help me decide to stay or upgrade
 

well i think im going to stay with the 50trim for awhile then at least this year. But hey ill pass on the sweet deal. Theres a guy on widsm.org wanting to straight u trade a scm61 for a evo3 16g. Widsm.org is doing matinence right now but will be back up
