50 trim installed, finally!

[sarge]

I picked up one of the Precision turbo SCM 50 trim turbos about 2 months ago (the one rated for 450hp). Jay and matt (if you are in the carolinadsm club you have probably met these two guys) were kind enough to install my turbo on christmas day. the 50 trim replaced my frank Jr. 17c turbo. The 17c was a pretty good turbo, but I decided I wanted to go to something bigger.

Well, later on christmas day i picked the car up. Boost was set at 12psi, and it was incredibly strong there, roughly like 17-19psi on the 17c. Several days after that i messed around with the wastegate actuator arm and got the base boost level up to 15psi. 15psi on this thing is fast. About as fast as the supercharged roush stage 3 mustang. I happened to run into one on the highway about a week ago, and from 60-140mph, he had less than 2 cars on me. Later I talked to the guy and his mustang put down 328.8whp, and ran the 1/8th mile in 8.07, so I am guessing that my car is making somewhere close to 300whp. Thats just a rough guess though.

The pte 50 trim w/.63 ar is an excellent turbo. I have this in conjunction with the dejon tool 3 inch intake. I can hit full boost in 2nd gear at less than 4000rpm, and in gears 3-5, it hits full boost by about 3600-3700rpm. Very impressive for a turbo that size i think. Currently its pretty untuned. I took the SAFC settings for a big 16g equipped car and 550's and FMIC from RRE, and just added several % more fuel in the 4-7500rpm range. EGT's peak at about 850C on runs from 0-120mph. I was planning on on having the car dyno tuned at 17-18psi, but my car started to burn more oil than usual (valve stem seals are starting to go, 120k miles on them). So instead I will have the head rebuilt on my car, then probably in the summer get it dynotuned after the head rebuild. Or, if you guys think that dynotuning will still be effective on a car that has bad valve stem seals/guides i may go ahead and have it done.

I didn't see any good reviews of these turbos, so I figured I would write one. Tell me what you guys think!

450whp or so, with that turbo 20-24 psi is what id be running.

well, when the temp decides to get above like 25 degrees outside, i will go play withthe boost controller

Been reading your post with great interest since pretty much decided to order a 50 trim in next couple of days.Its good news about the boost creep thing as I was a bit worried about internal gate on a 50trim.I was planning on big big tubular 02 housing so sounds like if your 2g one is good then the tubular should work fine on my 1g.An external might be an option but it is more bucks and right now would rather put the extra into a front mount intercooler to go with the 50trim

I was kinda hoping it would hit more like a sledgehammer than a velvet glove but it sounds like it gets plenty scary as you keep your foot in it and assume at 20psi a level that should be attainable with my 650's ,supra tt pump and planned fmic I imagine it would indeed be a street terror.

So no big complaints for lag or around town driveability??

Sounds like have to get me one of these asap..!!!

it hits hard if you punch it at 4000rpm + in gears 2-3, or even in 4th above 80mph, the thing goes nuts, the other day i was messing around and just punching it in 2nd as i drove around town, the thing goes 40-70 insanely fast, and thats only 16psi,

the turbo will hit full boost by 3700rpm or so if you start from low rpm, but start above 3700rpm and then stomp it, holy crap does that thing spool fast


driveability is fine i think, i generally take revs up to 4500rpm when just travelling around town, so thats a good 1500rpm right there of at least some boost ~5psi or so at maybe 30-40% throttle

this thing moves a whole lot of air, so you dont have to be heavy boosting or heavy throttle to be going fast

reading this thread makes me want my 50 even more.. this little big16g aint cutting it.. soon enough.. i dream of the look on my face the first time i do an AWD launch with a 50 trim at only 18 psi..

 

[TSi999]

this turbo is like a dream, it is amazing and truly turns a DSM into a true supercar/

The guys at LS1.com were talking about how low a price you can pick up a Turbo DSM and its boltons. Saying how a 300whp EVO III 16G for $550 bucks adds about 100whp and pissed because he paid about $800 for a Corsa Exhaust that added mabye 3whp on his LS1 V8..

Once again another reason why Turbo DSM's are the BEST cars in the world for the money. With a big Turbo you have the power of a big V8 or even a V12 but with 4 cylinder lightweight, agility and offboost economy. Just reasons why:

My PTE 50 Trim (G50) from Slowboy just came in tonight and let me just say that I just about wet myself when I lifted it out of the box. Definatly a dream come true for any DSMer!

 

[AL92]

I also ordered a 50trim although AGP RS49 with internal gate.I hope it don't creep bad but figure can run it at 17psi or so with my current mods and maybe higher when get a decent fmic.I got evo 02 and didn't get it ported yet and matching evo exhaust manifold also non ported.

So see how it works out.I was seriously leaning to the evo big 16 too but this does seem like it should get me into the 11s maybe.

I would think I should have it on the car in couple of weeks.You guys have me all hyper now.

Oh and I also own a 99 ls1 trans am modded to about 450 at the engine.Its fast but they are heavy..Around 3500.A bit more than awds and quite a bit more than fwds.And mods are very expensive.I bought my talon for less than the price of top of the line ls1 aftermarket heads!!!

The talon is great bang for the buck.But just so you know the ta still gets amazing mileage maybe better than the talon.They have six speeds you know..two overdrives.In sixth the car is taching like 1500 rpm with stock 3.42 gears.

Also the cars will go like 162mph stock and run in the thirteens stock with any kind of driver.With my current power though I run a best so far of only 13.35 at 109mph.That is with big traction problems on street rubber.And didn't shift without lifting the gas yet either.Also at 2000 feet above sea level here ..Still the top end charge is amazing and the car will likely do 180 plus mph right now.And easily be in the 12s on drag type rubber.

Anyway think my 92 talon with the 50 trim should be my fastest car for awhile especially on street tires.

I also have a 454 powered 80 trans am that I am building up with nice blower and spray.

Anyway sorry to ramble here.But ls1.com did come up.

Great site ive been a member there for years, great anything goes fourm..

Speaking of V8's Ive driven a 96 LT4 Corvette, then a 98 T/A and then a 00 Camaro SS that I turned in last year. All awesome machines but I dont ever really miss them, the DSM is just that much of an enthusiast dream IMO!

The Talon was basically a stock daily driver back when I had Camaro but now that ive turned up the boost and started modding it I really dont miss the Camaro at all considering the Talon is paid for!

by the way that 80 Trans Am sounds like an awesome machine!!!


Back on topic, ive got to see about one of these turbos someday.

With that "50 trim", a nice aftermarket side mount and a 20hp dry nitrous shot along with a 2800lb 2wd DSM curb weight and some slicks I think that the TSi should be real potent for some V8 hunting !

I finally got go to the track with my PTE 50 trim. 12.3@112

 

[AL92]

How about a bit more track info there...what psi?? Race gas or pump..
What 60fts? What sort of tires.??

Now please don't take this the wrong way but if my 50 trim can't get deep into the 11's with say 25 psi and good gas and with some cams and a good fmic its going to be yanked out of there and a ball bearing turbo like a fp 3052 will be put in its place.

The mph seems way low to me.Now maybe some tuning will make the difference but you aleady have a maft and stuff like me.I also assume in your sig the cams are 264/272 hks??

So how the heck do guys get super high mph out of these 50 trims.Do you have to lighten your cars way way down? I have seen evos hit 112 pretty regularly and one guy said he hit 118 with his and similar times think it was like 12.2.

I was going to get an evo but figured the 50 trim would let me hit the 11s and then could be within reach even of 10s on 75 shot of spray.

Anyone else with 50trims want to chime in here.Have you gotten into the 11s on yours and what mods,race weight,60fts. I look on the times part of the forum but mabye some guys haven't bothered to post yet for whatever reason.And I don't need to see a timeslip guys to believe you.

And again,its not that a low twelve is a bad time at all ,its decent but guy up near me hits 12.8 at 108 or so on his 14b.Now maybe the secret to getting high mph out of these 50trims is to not let up the gas on shifts,shift higher by raising stock rev limiter with cams ,not sure what else.

So again,not trying to belittle your run just wondering about a few details.

That is Shape's car your talking about. He ran a 12.4 or 12.5 with only a b16g or s16g before he ran 12.2 on the new evo16g. I think his car was just fast from birth or something. I'm impressed that people are simply slapping these things (50 trims) on with little to no tuning and running low 12s. Harcore tuning and other little helpers will undoubtedly yield your desired 11s.

Sarge...I got a few questions...

Did you go straight from a t25 to a 50 trim? Were you running all the 50 trim supporting mods (FMIC, 660cc injectors, etc.) all on the t25 at one time? Would there be any negative effects to doing so? Anything else you would like to add about going from "not shit" to "the shit?"

Thanks,
Jake

i did not go from t25 to the 50 trim

i went from a t25 with intake cone and exhaust+dp to a 17c, then to 50 trim

i ran the 17c for about 8months without supporting mods (put down 222whp and 230tq @ 18psi like this) then i got, in this order, straight pipe, hard upper IC pipes, fuel support (walbro 255, and FIC 550's and apexi SAFC,) i then turned the boost up to 20-21psi and added enough fuel to keep the car under 900 degrees C on the egt, i always meant to get the car dynotuned but didnt get around to it, so after 20k miles and about a year and a half i bought the pte 50 (i need 660cc injectors, but i am gonna work with my 550s for the time being)

Thats my turbo/mod history, by the time i got the 50 trim on, i had the supporting mods on my car (550's may be a bit iffy with this turbo, we will soon find out). If you are careful you can run the turbo if you do not have all of the supporting mods, but you will probably not get the gains you want.

15psi on the 50 trim is how 20-21psi was on my 17c, and i have been told over and over the turbo makes serious power closer to 20psi


if you are used to fast cars, and know how to handle power appropriately, then i do not see why you could not go from a t25 to a 50 trim, i grew up with my dad having fast cars, and learned to drive on a eurospec M6 bmw, and then on a 930 ruf turbo. so i know power and stupidity can kill you real fast, so i try to be careful and pay attention when i get on the gas big time. if you feel like you need to go big, then this is one of the turbos to get

Was this 50 Trim a bolt or did it require an install kit?

What 50 trim turbos DO NOT require an install kit?

 

[jake98gst]

Look at Extreme PSI. They have 50 trim kits with install kits. It pretty much looks like a 2g 16g install kit without j-pipes. It would be a bolt-on affair with the kit.

i got the 50 trim from precision turbo

it bolted right on, but we did have to trim a very small bit of the radiator fan for clearance, also, you may have to dent a certain water pipe so that the bell housing on the turbo will clear, its a very tight fit

you will need a hi flow oil line kit for the turbo, that runs about 85 bucks if you get it from buschur racing

 

[1badtsi]

or just get the whole kit from extreme psi for 999!

I hope your kidding. I've seen a stock 2g 7-bolt scatter at about 350whp, granted this wasnt the ONLY time it saw that power, but nonetheless. Stock 6-bolt would be right around 450whp.

The 50 trim is definetly an awesome street/pump gas turbo.

Why is the car for sale JDMAWD?

you would be dissappointed to hear that a member of the carolina dsm club put down 453 awhp with his stock 2g motor with 50 trim


we all know 6 bolts are stronger, but still
