ive been looking for turbo upgrades ive been looking at the t28 small 16g and the big 16 and evo 3 turbos wich of these turbos would be good for around 300 to 350 ive already looked into injectors fuel pump o2 housings downpipe and cat back
and which one of these turbos could run good with stock injectors or 550cc injectors and without tuning or putting a better fuel pump
 
I ran an Evo 3 16G on stock injectors and fuel pump.

Had to keep the boost down all the way. It was slower than stock. It sucked and i wasted money in all the wrong places first.

You can't put bigger turbos on without the supporting mods. End of story.
 
How about you save your engine and upgrade in the proper order Tech Guide: 2G 4G63t Upgrades - DSMtuners.

Make sure you have enough fuel before tyring to put on a larger turbo and with more fuel comes tuning so you aren't running pig rich. Searching and learning will be your best friend with the car and it's all been covered MANY times before. You'll be hard pressed to hit 350 with a 16g but it is "doable" but take a lot of work to get there. You'll also need more than 550cc injectors to hit more than 300hp I'd say. That said, you'll need a larger fuel pump and a tuning device as stated earlier.

Make sure all of your maintaince and repairs are done first before ANY upgrading. When was your timing belt assembly last changed???
 
Im sure some rc 550's and a wally 190 would cover a 16g. and 300-350hp is def a possibility seeing as the guy who tuned both my talons dynoed at 451.7whp 418.0 lb. - ft. trq on his big 16g he also is FWD and any nonbelievers out there i got a link to his dynosheet if you really want to go there :p Good luck with the upgrades.

EDIT:BUT if your going for the 300-350 mark i would say go with the wally 255 the 190 im sure would suffice to run low boost on the big 16 but dont quote me on this just trying to point you in the right direction.

thanks for the advice
well i was looking at fuel pumps and was wondering will a walbro 190lph work and im not sure what kind of injectors would be good

If your aim is around 350hp, its going to have to be a 255lph. Like Liquid said, you're gonna need supporting mods. I had a '91 GST with a 190lph, 550cc denso injectors and an EVO 3 manifold and EVO 3 16g with a 2.5 catback on a healthy stock engine @12 psi and tuned with a SAFC II and its nowhere near 250hp.

If you want to break the 300hp barrier, it will take more than bolt-ons.

Good luck.

You can get away with doing a 190lph fuel pump, 650cc injectors and SAFC-2 if you want to go a more affordable route. The 190 doesn't require an AFPR but it's still good to have regardless if you go 255 or 190. If you feel you'll want to go bigger in the future, just get the 255 and an AFPR.

The SAFC will only work decently up to 750's after that, it's about time to find another tuning device. However, there are other tuners you can choose to do besides SAFC. 95 ECU+ECMLink or a chip from a vendor or burn your own. You can also get a 99 flash-able ECU, download a couple of programs and do your own tuning which is similar to Link, but cheaper over all I believe.

The 16G is capable of good numbers, it's just not common for most people to achieve 4xx numbers from one without a lot of work and fine tuning. If you feel you are willing to spend a little more on a turbo setup, fuel, tuning and exhaust, then I would recommend going with a Holset HX35 in a BEP housing DSM flanged. There are multiple threads containing information on it and the HX35 and 40 can be had for cheap if you look around. It's defiantly capable of 400 and is a great street turbo. Just another option for you.

You will need a full exhaust system too preferably 3" for later upgrading :thumb:

Some Holset information if you choose to check it out. Thread 7 contains many other links inside of it on the main page that have more information.

Don't forget to do all maintaince and repairs first! Follow this guide for a proper order to do your build.

Well, I did provide you with the links to see what others are running for what you want to do. You can base your build off of theirs. Ultimatly it all depends on what you plan on doing in the long run. Do you want to make more HP down the road or no? If not, just stick with a SAFC and some 650cc injectors and a 190lph pump. Otherwise I would say get a true fuel management system/logger, get some decently sized injectors so you don't spend moeny twice, 255lhp pump, AFPR and any other supporting mods. If you liked the information I provided, click on the "tag this post as helpful" on my above post :thumb:

You mean to say "dumped". A dumped o2 housing is to give better boost control as long as you don't have emissions and can deal with an exhaust leak every time you go WOT and hit your boost limit. Smaller the turbo, the more you'll be dumping as they will spool faster. A recirculated o2 is just as fine as well; not only is it greener, it's quieter and fully capable of allowing bypassed exhaust gas back into the exhaust stream post turbo. If you go with an o2 housing mounted external wastegate, the dumped housings are cheaper from what I've seen if that's a factor for you.

Not on pump gas with no bottle. He must of been on E85. I know numerous guys making 400whp on E85 with 16g turbos

Personally, I would do a Walbro 255 fuel pump, fuel pressure regulator, and injectors. You will also need to tune it and I highly recomend atleast DSMlinkv2 or ECmlinkv3 if you have the cash. If your looking for 300whp, a s16g would do fine. Looking for 350+, an evo3 would get you there. I was at 98% IDC on 560cc injectors at 25psi on a S16g. I would go with 660cc for anything around 350whp and thats cutting it close. With dsmlink/ecmlink, go with a 780cc or something.
 
im sorry if i didnt clear myself i tried to say like which one is better like durabilily things like that
i did some research on both of them i read that the t28 you need to do some modifying but i also read that it was a direct bolt on.
And the 16g for instalation you need to buy the kit for the 2gs and i also found out that they may leak from the wastegate
 
will the evo 3 16 and the small 16g will bolt up to the stock 2g turbo manifold

ok so im sticking with the EVO 3 16G
but im not sure what injectors i shoud get which ones would yall recomend
and i will probably get the 190lph pump
and for tunning ill get the SAFC
and will this set up be good for 300hp?

Seriously dude, you need to read the posts I made and look at the links as well. Everything you have been asking is available on those threads. Also please use the search button as well. I've been very patient with you on this thread as it's the kind of topic that is always around but it shouldn't be posted this often.

The dyno challenge links I sent you will give you the information and the ability to see what the other members are running (assuming they filled out their profile) with the numbers they are making. Please use the provided information :banghead:
 
sorry man im just trying to do everything the right way u know i already look at them but i just want to do everything the right way

And I posted the right way all within those links. Follow the upgrade path AFTER your maintaince. Use the dyno sheet to find the numbers you want and base your upgrades on what those drivers are utilizing. I know you want to do things right, I felt the sameway too, but when this much CORRECT info is flowing on this kind of thread, take heed to it please.

To answer one of your questions, yes the 16g will bolt up to the stock exhaust manifold. It's "DSM/bolt on" flanged.
 
The are "all" easy to use once you understand on how they work. It's just some are easier to learn than others and a few out there while easy to use are just a pain to get an accurate and consistant tune. It all comes down the the amount of money you want to put in your car and what your overall gains are to be. I would personally say get ECMLink with a 2g EPROM ECU, but that can cost you anywhere from $500-$800 depending on if you get it all new or used.

You can get a used SAFC on marketplace for cheap as well and will work fine for up to 750cc injectors. It is however not the best tuning device out there as you will also need a logger to use it properly and can only go do so much with it. The bigger the injectors, the harder it is to get the proper tune with the SAFC.

OR, you can just get an EPROM ecu and have a chip burned for your setup and not have to worry about tuning. However, each performance upgrade should be taken into account when you have a preset chip for your setup. This way would be the "hassle free" way for you until you start upgrading afterwards and you just need to get the chip re burned.
 
thanks man
i had another question sorry if im asking so many will cams help me reach the 300 goal and which ones do yall recomend?

is the apexi afc neo good? and would i need the logger for it too
