A 50 trim is a common upgrade here. It'll spool a lot slower than the T25 but the top end is nice. If tuned right, it can pull all the way to redline on some 272 cams. It's more preferred than the 20g and majority of the time it'll still retain a Mitsu housing for bolt on applicability. The only other turbo that can beat it in terms of power and efficiency right now is the Holset.

I just put a 50 trim on my car. Significant upgrade from stock. How are you controlling your fuel?

 

[DSMsOwnYourV8]

50 Trim, Exhaust, Fmic, Fuel... Doesn't look pretty much stock to me. What are your goals for the car? You'll need some way to tune.

 

[crimsondragon]

He has a Translator although not a very good tool to tune with, it's still tuning.

 

[welfle18]

Yeah but tuning with just the GMFT with 680's is almost rocket science. I would look into purchasing like a afc or safc to control your fuel. Link would be the best though. Things you should look into.

Talonnightracer - Please use punctuation and capitalization when posting in the tech forums. I had to read your post twice to even find your question...

The answer to your question is, "no".

 

[Talonnightracer]

it has dsm link

 

[welfle18]

Haha I see you didnt metion that, well then I agree that your talon is far from pretty much stock. What about a clutch. You are gonna need one soon if stock because the stock one wont he able to run that kindof torque. But it seems you have plenty of upgrades to handle a 50 trim.

 

[sjm531]

an upgraded clutch and maybe transmission would be good, but i think he means "stock block and/or stock head". if you want, i could take that 50 trim off your hands if you want. jk, but it sounds like you have enough supporting mods for a safe 400hp street/strip monster.

 

[No_Skillz]

You have the proper hardware to support your 50-trim, but that does not include everything needed for efficient usage nor does it imply owner sensitibilities. You will need ARP head studs to run more than 20psi on your current setup. Otherwise, your 50-trim is not even in its most efficient range.

Furthermore, you are making significantly more power than stock, which also means there is alot less room for error in terms of tuning and driving. Get a decent tune (might want bigger injectors), watch your knock, and don't be stupid on the streets.

 

[welfle18]

With a good tune will a 50 trim and say 23 lbs out run the stock head bolts. I want to know because I have a 50 trim and still stock block head. I am only running 15 lbs till I get all the kinks worked out but I am anxious to turn up the boost. Sorry to hijack the thread but some of this info applies to me too. Thanks

I never understood this, unless it has to do with pricing. The TD06 20G is still better balanced in terms of flow, and is designed to be used in the Mitsu turbine housing. It is more expensive, however.

I've yet to see a company (except maybe FP) design a bolt-on turbine housing that allows the Garrett T31 turbine to flow at it's potential, not to mention the Garrett's poor reliability on our cars. I've been rebuilding turbos quite a while and I've seen many more Garretts fail for no reason than Mitsu turbos....almost 10 to 1. If you give a Garrett too much oil pressure, the turbine seal leaks and will eventually ruin the journal bearings...give it too little volume and the thrust plates fail, causing excessive in/out play that ruins the compressor wheel immediately.

I'll rebuild Garretts for customers, but I'm done recommending them as a good upgrade.

I ran 21psi and blew the HG after a few thousand miles. If I could do it over again, I would not go near 20psi on a stock HG. Probably 18psi max.

 

[welfle18]

I see. Well maybe I will keep down until I eventually rebuild my built engine. Hopefully in the next year or so.

 

[No_Skillz]

Sorry, just to be clear, when I said "stock HG" I meant "stock HG and stock head bolts." I use the OEM HG with ARPs.

 

[1992awdlaser]

You need bigger injectors. Those injectors can be maxed out with a 16G running pump gas. New clutch is also a good idea. Look at the mods listed in my profile and you will have a good idea of what a very well built 50trim has. Some of the things are not needed but they help it perform better. I wouldn't recommend the clutch I have for the 50 trim thought(I bought it when I was going to use a 16G).


I am running 25-28psi on my stock block and head and am confident it will handle more when I go to the track. I have the FP2's with stock valve train and I rev to 8,000 currently. I am think about revving a little higher.







There are quite a few guys running high 20's psi-high 30's psi on stock over tightened head bolts. Obviously, I don't recommend this but it has been proven to work.

x2
i ran exactly 20lbs and after about 1thousand miles i popped the headgasket. went with a stock cometic HG and arp's

Thank You!! Everyone thought I was crazy to want a TDO6H 20g.

To the OP: "50 Trim" is a very vague description of a turbo. Refer to my thread here for why: http://www.dsmtuners.com/forums/turbo-system-tech/309790-16g-50-trim.html

And it's ok, I still consider my car stock too...

 

[RedTurboEclipse]

I run 21-22lbs all the time on stock hg with my 50 trim and stock 7 bolt..

ran 20-21 all the time with my other gsx on mhi b16g stock 7 bolt..

i start to worry at 23+

and Talonnightracer, thats far from stock buddy..hope you knew what you were getting yourself into when buying a pretty modded DSM.. esp if its not your first..

 

[welfle18]

I am curious when you say overtightend stock bolts how much torque more was applied as I might so this for now until I can complete my build further down the road.

 

[kawboy]

I ran 24 spiking 27 for 6k miles and my headgasket was mint.

 

[Talonnightracer]

The talon is automatic. but i am gettin out of this is i should put bigger injectors, get it tuned right, run about 18psi until i get bigger heads, and make sure my fuel ratio is good!!am i correct!!

 

[UGOT8UP]

If you think you got to much turbo for your car Ill trade with ya

 

[Talonnightracer]

im cool!!thnx though i just hav a couple buudys that say i do but i dnt think i do thats y i am asking!!
