The turbo in my car is blown out and I need a new one. The only mods that I have done to the car so far are: Balance shaft removal, conic air filter, and all the free mods. I want to get a turbo that I won't have to ever upgrade out of, if that is possible.

I was looking at the 57trim G series turbo from slowboyracing.com. It says that it is good for up to 425Hp. If I get this turbo what else will have have to get for my car also. I know that I will be getting a FMIC to go along with ir because my puny little SMIC is all beat up and I was going to get a new one someday anyway. What Kind of intercooler do you guys think is good to get? Is there a certain size that I should be looking at? Is a kit better to get or will custom done pipes be good enough? What other kind of stuff will I need to or should get: BOV, oil cooler, fuel components, boost controller. Also, that particular turbo does come with its own external wastegate, right?

Thanks for the help and suggestions.
 
Ok let me lay it out. Get a 50 trim. You will thank me later.
Bigger injectors
Fuel control (SAFC or DSMLink)
2100-2600 clutch
Bigger exhaust
Intake
FMIC if you want to take advantage of high boost
(sorry if you have some of these mods, I didn't look at your profile)
If i forgot anything correct me.

I agree with this.
Throwing THAT LARGE of a turbo on your stock car is gonna kill your performance as well as every other aspect of the car. Plus you run the risk of running to lean in boost and all other smaller complications.

Don't go that big unless you have more money for other upgrades also.
 
Ok, I'm down to a 50-trim.

Do I really need to get new injectors and fuel controll and new exhaust?

Also, Will my turbo overheat if I hook it up to my little stock intercooler?

Honestly?
If your like 90% stock I wouldn't go with a 50trim.
In your case I would be doing a heavily ported evo16g.
 
The thing is, I don't really want to have to go and buy a new turbo a couple of years latter when I max out a smaller turbo. About how much Hp can a Big ported out 16g supply air for?

What would the side effects of getting the 50-trim be?
And, do I really have to get new injectors and a fuel pump If I go with the 50-trim?
 
You should be getting injectors/pump and rewire/fuel management with even the b16g if you want to fully maximize its effectiveness. On the stock fuel system without any management or tuning I'm guessing you'll be restricted to pretty low boost and be unsatisfied anyways. To get the most out of a 50 trim you'll need a LOT more supporting mods (basically all of stage 1).
It all depends on your power goals really, but unless you're shooting for some huge numbers an evo big 16g will probably get you there without any problems (many people have ran many good times with this turbo).
If you just want some street performance I'd say maybe go with a TD05H 14b, since this is a cheaper way to go, and still outright owns your old turbo. Plus if you install everything you can easily go to a 16g or 20g since you have all the piping made.

There is no way you can just slap a turbo the size of a 50 trim right on without the supporting mods you need.

The only mods that I have done to the car so far are: Balance shaft removal, conic air filter, and all the free mods. I want to get a turbo that I won't have to ever upgrade out of, if that is possible.

Sorry, thats not possible with your mods. Basically you just have free mods, so your looking at:

- The whole 50 trim kit (turbo, T3/T4 manifold, External WG (if chosen), etc..)
- 660cc+ injectors
- 190lph or 255lhp fuel pump
- AFPR
- Something to tune with (SAFC etc...)
- FMIC with piping
- 1G or aftermarket BOV
- A better holding clutch like an ACT 2600
- and a 3" turbo back exhaust

Sorry bud, but your about $3K-$4K away from reaching 50 trim status. If you want to upgrade, go for a used 14B or a small 16G. I wouldnt even go Evo III B16G at the point your at now, your stock.

The last bit of advise I can give is to use the search function and read about write up's of the turbo's your interested in. They will give you an idea of what supporting mods you will need to safely and efficiently run that particular turbo. Do alot of research, because obviously someone who thinks slapping a 50 trim turbo on a stock car with stock fuel really doesnt know what they are getting themself into.

This link helps to get you started with the mod process:

http://www.dsmtuners.com/tuning-guide/2gturbo/
 
Funny Funny, a link to the tuning guide.

I have read over that as well as the faq and you I do plan on going back on doing all of those mods. It's just that My Turbo is blown out now.

If I get a 50-trim externally wastagated.
750cc or so injectors
FMIC

Would that be alright untill I get time and money to do all the other mods.

Also, I thought the the cat back part of the exhause wan't causing all that much flow restrictions. I thought that it mostly was the downpipe that was blocking exhaust flow.
 
if you must get the 50trim now you will need everything for mounting the turbo itself plus at a minimum for safety- a manual boost controller, a boost guage and mount, big injectors, a big fuel pump, a rewire to run the big fuel pump, an adjustable fuel pressure regulator, a datalogger and some way to tune, get a used safc for cheap to hold you over until you can afford dsmlink. this is basicly doing everything at once, and it will probably be a nightmare since you sound like you dont know the car too well yet. why not just buy a used 14b off the trader and then build up the rest of the setup around that, then when you are ready just sell the 14b, pop the big guy in there and not mess with a laggy lowpsi big turbo on a poorly supported car. unless you can afford to do it all right, all at once i wouldnt go that big yet. thats me though.
 
Ok, I guess it sound like going for a 50-trim right now would be a bad idea.

If I go for a B16G am I still going to need all those new fuel components?
 
you will eventually but they are not needed up front.. when you do end up getting them all it means is you can turn up the boost even more :D look at the mods in my sig, i am on a totally stock fuel system other than a 10$ rewire of the stock pump and the car handles 18psi with no problem. datalogs show a steady increase of timing to 20 at the shift at 6800 with o2's steady at .92. my bigt28 is very similar to the big16g so your results on a properly running car should be no different. i am on stock exhaust though, i imagine i would probably be taxing the stock injectors and pump if i put on a 3" now so my next steps are doing the same fuel mods you are talking about because i too plan on getting a 50 trim down the road.. just not until the rest of the car is up to the task :)
 
oh yeah, a uicp and blowoff valve that dont totally suck are an absolute necessity as well for running any decent amount of boost. believe everything you have heard about the shittiness of the stock bov, when i put on my type s the same mbc setting that got me 15psi on the stock bov got me around 22 on the greddy. innefficient and needless wear on the turbo.
 
sam, you're on 18 psi on the T28 with stock injectors and just a fuel pump rewire? What CFM or lb/min is that do you know (can't find a flow chart for it right now)
 
Ok, It looks Like a B16G is as big as I can go without fuel.

So now its time to figure out the intercooler setup that I need.

What do you guys think of the dejion tool race FMIC? It seems kind of pricey, is there one that is a better alternative somewhere that I haven't found.
 
Does it really matter what core you go with?

Will all of these pretty much work out the same:
Dejion Tool
PTE
Slow Boy Racing
 
2ggsx- i peak at 27 lbs/min at around 6600rpms with 20 degrees of timing. my exhaust system is totally stock so the numbers are lower than what they would be otherwise, but i am using that as a buffer to run 18psi until i can get my fuel upgraded. then on goes the exhaust, up goes the boost and up go the lbs/min numbers :D
 
I was searching around today and it looks like everone has a problem with boost creep with their 16G's.

Does anyone know where I could get a T-25 for really cheap? I think that I will just have to stick with that untill I can dump some more money into my setup and have all the necessary support for my 50 something trim turbo.

i have big 16g and no boost creep, of course i have 3" buschur exhaust and 3" dp, dump tube, bla bla, no creep there

Smart move.

Either go a small 16g/evo16g (keeping the boost down)/big t28 but I ran a big t28 on a completely stock car other than an upper Ic pipe and a bov.

:shrugs: I don't know, since you don't have alot of cash to work with a bigger turbo shouldn't be purchased.
