PTE scm6176r turbo ???

[90laserRSfwd]

Found this turbo when looking around on Extremepsi's website the other day. It's manufactured by Precision Turbo. Just wondering if anyone has any info on this turbo or if they're using it on there street car. I just sold my scm6152e and am looking to get another PTE turbo. This one (scm6176r) is a bolt on just like the 6152e was. It goes for around 1300 with the install kit and the SP ported shroud. It's basically a gt35r that bolts onto the mitsu exh. and o2 housings from what I gather.

First off, don't be fooled by the 680 hp rating they give this turbo. Most guys using these turbos are probably making between 400 and 520 whp.
I am using an scm6176 on a race built 2.4 engine with fp3 cams and It makes great power but its not that fun to drive.
At the end of the day your turbo choice really boils down to how you drive your car.

If you just want a cheap turbo to use on a car that you drag race alot then the scm61 will make quite a bit of power with decent spool without having to upgrade manifolds. I bought my journal bearing model internally gated for $800 3 years ago, but in hindsight I wish I would have spent the extra cash for a better turbo. Like most things in life you get what you pay for and there is a reason my turbo was cheap.

If you enjoy daily driving, autocross or road racing your car I wouldn't recommend the SCM6176 especially on a 2 liter engine. On my old stock 7 bolt this turbo was very laggy and not fun to drive at all on the street in my opinion. Even with the larger race built engine I have now the scm61 responds like an on/off switch. The transient response is poor on the journal bearing model and the car just feels dead at partial throttle and it seems weak until around 4000 rpms and then it slams you back in your seat. Don't get me wrong, this turbo makes great power and is capable of 530+whp with lots of boost and race gas, but there are many turbo's that can get you there without sacrificing as much driveability. The truth of the matter is that the stock 1g and 2g exhaust manifolds suck and they are both very restrictive at the power levels this turbo is intended for. The internal gate does a poor job controlling boost above 28psi and you will need to reach those levels to get this turbo into the appropriate power/efficiency range. I notice that your looking at a ball bearing model which should at least have better transient response than mine, but I still wouldn't recommend it.

If you insist on going cheap and using the stock manifold get an fp3065 instead of the scm61. The 3065 will make just as much power as the 61 and spool like a 16g with great transient response and reliability due to it's efficient chra and ball bearing design.

If you really want to do it right, spend a little extra money on a nice DNP, Shearer, or Full race T3 or T4 divided exhaust manifold and a twin scroll 3071 or 3076 turbo with a tial 44mm wastegate. It should be as fun to drive as the stock turbo and make as much power as the 61, perfect for a fun daily driver or autocross car yet still capable of 10 second 1\4mile times.

If you want a car capable of 9s thats not quite as fun to drive as a gt30 an HTA 35R or a twin scroll 4088r are both capable of over 700whp and should be more fun to drive than the scm61 as well. In fact, even if your not that concerned with driveability and don't mind a lot of lag you would still be better suited with a journal bearing 4294R. At least then you could make up for all that lag by making 1000whp!

Call Geoff at full-race.com or the guys at ForcedPerformance.com and let them help you with your decision. Don't be a cheap skate like me, it will cost you more in the long run. Do it right the first time, or else you'll be dropping another 2 grand later to get what you really want.

Cheers,

Josh

Pm me or email me at [email protected] for more information.

I made 462whp@34psi on a stock crappy crappy engine.
My friends daughter made 592whp at 32psi on the same dyno with a nicely done 2.0L. Just was missing a batter intake manifold than the 1G.

I think with the right setup, this turbo will put down 600whp with a 3" T04E cover. And oer 650whp with a T04S or T04H cover. This turbo is sick. It is now on a friend's full weight 2G. At 21psi on pump gas, he lights the tires up no lift to shifting into second gear. Car should knock down an eleven second pass at altitude come spring time. Racing another 12.1@118 2G they were pretty much neck and neck. Just need better driving for both cars/drivers.

I would put it right below a true GT35 and above a FP3065. And this is speaking fro mexperience with both turbos.

Don't misunderstand me, I like my scm61 and I hope Stephen can help me squeeze over 550whp out of it , I just think there are much more efficient turbo's available now for similar prices. If your gonna drop $1200 on a turbo setup you might as well spend an extra few hundred dollars and get a good manifold and the most efficient/best all-around turbo you can buy. My comments on the 61 are based on it's spool and response not the potential power it can produce. I know this turbo will make great power with the right tune, but I have driven a 3065 car and ridden in a car with a ts 40r and the difference in how much fun the 3065 car was to drive due to partial throttle response and low boost power was night and day compared to my car. Also the power and street manners of the bb ts 4088 on a stroker is just sick. Regardless, I don't think anyone can argue that a t3 or t4 manifold (divided or not) with a ts gt30r, HTA 35R, bb PTE6776 or a ts bb gt40r turbo will outperform the old mitsu exhaust mani and mitsu turbine housing turbos in peak power, spool, transient response, and part throttle performance any day of the week. The only advantage of using a mitsu hotside is cost.

Check out what turbo's some of the fastest DSM's in the world are using and make your own decision.

DSMTimes.org - Home

Notice, there are lots of 35r's, 3065's, gt40's and 37r (6776r) turbos on that list. There are only two sc61's at the bottom of the list and it looks like they weren't using a mitsu hotside.

BTW Stephen, I still need your help tuning if you have time.
