big 16G or 16G GT - tell me why

[themadhatter]

Looking to upgrade my galant's stock 14b to the next size up so I figure the 16g is about right.

I was shopping on turbochargers.com and they advertise their own 16G GT vs the traditional evo III 16G. I'd appreciate some insight on this before I make my purchase.

I'm not limited to 16Gs, if you can recommend a garrett or other, let me know why you think it's a better idea.

I'm looking to get 320+ awhp for my winter beater. last dyno pulled 282 awhp at 18 psi on 93 octane.

current mods that are relevent to this upgrade are:

supra fuel pump
3" turbo back exhaust - no cats
Apexi S-AFC2
Gen II mas air (sits where the battery used to be)

I'm guessing fuel injectors will need to be upgraded, but what size appropriate? your input is appreciated.

Last I read a few months ago on dsmtuners, the 16g GT is a chinese made knockoff of a real 16g. They aren't made by MHI. Go with the evo3 16g if you want to make that kind of power, or something bigger like a garrett setup or a 20g if you want some more potential. I had 650cc injectors on my 1g w/ an e316g, but fuel control was kind of a mess in low rpms. I'd use 550's for a 16g if i could do it again.

I just read the evo3 16g was definitely good for 400whp. That would be my choice.

Wasn't your car shooting tons of soot in one photo, lol.

I like the 550s as well. :) And consider getting an adjustable fuel pressure regulator. If you could log your fuel pressure now you would see it dropping and rising in a very erratic way. Simply put your stock fpr is not big enough to flow what your pump is putting out.

thanks for the info. about the 16g gt, the vendor clearly states that it's made in china so I don't think they are trying any trickery there. half the crap we buy today is made in china anyways, precision parts included. I would be interested to hear from anyone actually running the 16g gt for a couple thousand miles for their opinion since rumor can be nothing more then pipe smoke.

if I were to stick with an evo 3 16G, where is the best place to get it?

would it be possible to install a T60-1 (t3/04) on a 4G63? I may replace the turbo in my bimmer with a GT35R.

thanks again,
Ron

The EVO GT is made of different materials,your best source for info would be DSMTUNERS.COM.People have reported them dieying within as low as 600 miles while others love it, I have a b16g and if it should go i would get the Evo316g(mitsubishi) just cause i dont like having my vehicle used as a ginney pig.As far as injectors go it depends on the tuning aids available if all you have is an AFC i'd go with 550's, if a DSMLINK,MAFT,AEM EMS, is used on the car i would run a set of 650s .

[themadhatter]

thanks for the post. looks like the 16g is the more safe bet. the tuning will be done with the safc-2 but not by eyeballing it, it'll be dyno tuned at ICS Performance, www.icsperformance.com

is this a good idea or should I really go deaper with the tuning hardware?

I'm running a 60-1 compressor in my DSM. The turbo is actually a Mitsubishi/Garrett hybrid also known as the Forced Performance Red turbo. It's mostly Mitsubishi with the exception of the Garrett compressor wheel. And Mitsubishi turbos have a reputation for lasting much longer than Garrett turbos.

Unfortunately, this turbo would not go well with your setup. It will require a lot more supporting components just to run on your car.

interesting thread but it's about a different turbo all together.

this is the one I'm referring to, it uses a different casting and everything. manufactured in Taiwan, not China. their web site discusses the china gt as well:

Just keep in mind that if a turbo goes it is very possible it can wipe out your motor, too.

Not very common, but this happened to a person I know. Basically, the turbo bearings exploded, chunks and small debris fell into the oil pan, was circulated through the motor, and ate up bearings, cams, left gouges in the crank, etc.

Silly DSMr was trying to prove something by trying to be the fastest one with a stock turbo. Problem is over-spinning a turbo is never good.

If you crank your boost controller to 26++ and the most the turbo can put out is 21 psi at redline then your over-spinning it.

Its all about over boosting man! Look at me, I bought my car last month, its bone stock, I slapped on a 20g and turned teh boost up to 30psi(low boost), and I cant measure my high boost b/c my guage only goes up to 30 psi! :eek:








































Im just playing man....

Wil, I'm not gung ho about that 16g gt, it's just that I'm trying to cover every angle on the purchase. right now, I'm set on the evo 3 16g with 550 injectors, thanks to your advice and the others that have posted in in this thread.

I don't want it to be one of those 'damn, shoulda got the other brand' deals. I already did that with the ebc in my e36 and basically wasted the money there.

I agree on the over boosting, I limited the factory 14b to 18 psi since it's not worth grenading the motor by going the cheap route.

Ask me what size socket you need to pull a half axle off an e36 and I'm all game but
I'm a n00b when it comes to Japanese performance cars and trying to learn. I truely appreciate the advice you've given me.

DSMrs are generally a very helpful and down to earth group of people. One of the reasons I got hooked very early on and still with the car for over 15 years is when I was a noob everyone I met did their best to help me out, too.

I'm just trying to return that kindness by helping new DSMrs.

[themadhatter]

that's good to know, thanks. what forums could you recommend me for more detailed advice on this whip? I'm already on galantvr4.org but you can imagine that traffic is slow on there.

let me know if you ever pick up a bimmer so I can return the favor. :)
