OK so I just installed a boost gauge and with just an air intake im at 12-13 PSI. So my question is if I go to 16 PSI will I see noticeable gains? And another question can my stock bov handle that PSI?
 
"I'm telling you running 16 PSI in a stock T25, stock SMIC, and 390cc injectors is retarded/pointless without some supporting mods."

Last time I checked, 2g's came with 450s and the 1gs with the 13gs came with 390s...
 
Just turn your boost up to 12 and leave it at that till you get a bigger turbo with supporting mods. Thats exactly what i am doing right now. The 1g bov you ordered is a great piece to pick up. When i turned mine up to 12 i noticed the difference immediately. So just enjoy 12 psi while you get your mods in line. Good sound advice bro.

There, how's that?
 
I agree with everyone on here. I've only had my 99 GST for a week and I'm not going to drive it till all proper maitnence and checks have been done before I think about putting any money down for performance, I suggest you do the same. After that read the Stage 1 mods list and go from there, do all supporting mods before adding boost or any power if you still want to keep your car moving. You might feel slight gains from supporting mods but to be honest you'll give structure to your car and your wallet so you're not paying for a tow truck and rebuild.
 
Honda guys have no business buying a dsm. This site has gone full blown retarded damn hooplehead's hurry up and blow ur cars up. I need some fresh donors at the scrap yards[DOUBLEPOST=1417241297][/DOUBLEPOST]Psi means nothing. Notta zilch. T25 flows 305 cfm/min at 15psi. Anything past that is marginal gains. And ur just blowing hot air. If u want to learn. Then learn. Read the forums. Don't post up till u fully understand the workings of a turbo charged engine. If u don't get something read it again. Google it. U tube it. Insta gram or twitter. Whatever u kids do stop thinking more psi is the solution. It's not. It's cfm

I've read many threads stating you don't need any mods. I've read that the stock fp and injectors are fine for a t25 at 16psi. Im going to find everything I've read and post links so you guys can see.
Hey josh you are going to blow your car up reading those threads. Listen to some of these old timers and read the links they are providing carefully and you will go a long way in this dsm game!

You hve had your car for a week so please don't post like you know anything. I asked a question so I can learn. How else has any of these "old timers" gotten where they are? By reading and asking questions. And my car is 100% perfect and has zero problems. Nothing has to be fixed on it.

Hey now i have a Honda and know the value of displacement. I tune mibe for street on 15psi with a big 62mm turbo.. all cfm there... there is a lot of misinformation out there on turbos in general.

I do know these dsms can make some good power with minor mods if you stay on top of everything else first. I went over mine with a fine tooth comb before starting to collect parts. And i still wait to put them in until im confident ill have no issues. Im sure i could raise boost to 15 or 16 and be good to go but i want the extra security of bigger injectors and fuel pump for my own piece of mind.

Josh, FilmerDude actually has some good advice in that post. He's just reiterating what others in this thread have already said. Nobody is trying to attack you here. You're absolutely right, everyone has to start somewhere and reading and asking questions in the best way to start.

It's highly unlikely EVERYTHING on your car is 100% perfect. You're driving a nearly 20 year old DSM. The chances of something needing maintenance is highly probable. Possibly something you may have overlooked.

Why don't you start out by making a checklist of all the maintenance items you have attended to. Post them up here so others here can see them, and see if you have missed anything. Once you're sure you've got everything, then let others help you with the beginning stages of the 2G upgrade path. Please, don't take this as me/us patronizing you. It seems like you're new to the platform, and starting from the ground up is the way to start.

Reliable performance comes from building on a solid foundation. That foundation's cornerstone is maintenance, and the blueprint consists of a good plan that is tailored toward realistic build goals.

I had my friend that's a mechanic go through the car completely. The motor has no issues what so ever. I replaced all the pulleys and belts. The alternator and water pump. Tranny is rebuilt and he did a compression test and that was good too. The motor was rebuilt by the previous owner 40k miles ago (I'm the second owner) and I have a stack of receipts 2 inches high of all the times she took it in the worked on from the local mitsubishi dealer here. The car is solid so I'm now getting things together to upgrade it.

I just ordered a 1g bov and the adapter and now I'm looking at injectors but not sure what size I should get. And my buddy said he will rewire my fp so I'm set there.
 
Injectors do nothing without a way to tune for the add'l fuel, keep that in mind. It isn't a bad idea to rewire the FP though, it's fairly inexpensive and doesn't require any tuning after it's done.

I recommend spending money on a tuning option before getting injectors, i.e. ECMLink or EvoScan, but here's a link that will explain fueling requirements based off of airflow numbers so you know what injectors to get.

This is the consensus upgrade path provided by the site if you're interested ---> http://www.dsmtuners.com/threads/basic-horsepower-ugrades-2g-4g63t.480196/

This is the upgrade path a few site staff/experienced members helped put together, which I think's better than what we have published. Personally, this is the one I'd follow but I helped write it so... :)

Revised Upgrade Path
 
You won't need injectors on a t25. Save your money up. But if you do want to get injectors get 1000cc I bought 550 and ran out of injector fast. Plus you will need something to control them.
 
Moddding your car takes time and involves steps get a tuning device then you can adjust to what ever mods you get next, or plan to get. Im glad I got link before I got too deep into getting parts.
 
...to piggyback on what Vic said, a stock DSM can benefit from a tune with ECMLink and it's a lot easier to learn the software on a stock DSM than it is after you get fuel mods, cams, etc. ECMLink can even be used for troubleshooting problems too, it's not just a means of tuning.

I may have had my car for a week but I have been building a 98 GSX with a buddy for the past 3 years so don't go judging, I just want to help a fellow DSMer and not see you blow up the car. I wish you would've listed everything you did about the car in the beginning or put it on your profile and this thread could've been much shorter.
