Spyder 2G DSM - small 16g with stock everything fuel, injector, fuel pressure regular, stock intercooler help, advice, opinion, suggestion, recommendation???

(1997 eclipse gst, 2g dsm) Small 16g turbo upgrade from stock T25 turbo help.

Ok I did some research already and found some 2g DSM owners don't need bigger injector, bigger fuel pump, fuel pressure regulator, and some has it one or the other or has all 3 plus intercooler, intakes and exhaust and some don't have it at all just everything stocks so I found a mix of setup, reviews and opinions.

I need help with what's I should add to the small 16g without adding fuel pressure regulator and will be tune with DSMLink v3. I figure buy everything or all supporting mod but budget is limited so I can try to cut the cost down to as much as possible and don't want to mess with fuel pressure regulator as well for now.

Here is what I got the part so far. Injen intake, downpipe, 3 inch exhaust, DSMLink v3, 1g BOV or Evo 9 BOV and small 16g (I also have boost gauge, boost control and wideband but haven't install it yet).

Should I just upgrade 190 fuel pump and 550cc injector and front mount intercooler and then tune with DSMLink v3 so I don't need fuel pressure regulator? What's the best options for me and what have you done to your setup up too without adding fuel pressure regulator to runs safely and no fuel cut or boost creep or no problem?

Thank you everyone for your help.

your post is hard to read, from what it sounds like you are asking what you need to put a small 16g turbo on the car?

technically you dont need anything. the factory ecu will not let you run more than 13-14psi on the stock mass air flow sensor and stock ecu.

im running a small 16g on wastegate pressure (8psi) on my 2g. the car behaves like stock and has more power in the upper rpm's.

if youre asking how to hit a certain power number on the dyno? or what

you can run the small 16g on stock everything at 13-14 psi and it will be ok. you can run it at 8psi off of the wastegate and it will behave like stock. my car is all stock except for the intercooler piping and a catback exhaust. im even running the stock sidemount intercooler

What's your HP goal and what's the purpose of the car? This is the question you need to answer before any of your other questions can be answered.
I'd start with ECMLink first if you haven't already. That gives you the ability to tune a stock car and well beyond. From there you can upgrade each system as needed to support whatever your goal may be.

Thank you for the reply. one of my question is upgrade small 16g and leaves everything stock which Chrysler Kid touch on it.

As far as Dwb you question is yes I plan to aim close to 300 hp daily driving. But I want to install the small 16g first then run stock boost and then later upgrade the rest of the supporting mod to hit close to 300hp like bigger fuel pump, fuel injector, intercooler, fuel pressure regular and tune with dsmlink v3. I think I already had an idea what I am going to do, thanks guys for the help and advice.

there is a sticky for the upgrade path on a dsm


if you want to hit a horse power number you should expect to be the "dsm guy" and know how to perform a boost leak test in under 10 minutes. if you dont want to commit your brain power and wrench power to be the guy, you should expect to be regularly paying that dsm guy to fix your car

300whp may seem like its not a huge goal, but I reccomend making that a floating target. building a fun car thats reliable should be the ultimate goal. you may end up only making 250whp with your first setup, but by then you will have a clearer understanding of the next step of how your want your build

It all comes down to how much air you're flowing and whether you can supply sufficient fuel to the engine for your airflow. If you leave the boost level stock then you should be able to run it without issues. If you want to increase the boost you should add a fuel pump and injectors (190l/h and 550cc should be a good starting point, and maybe get you to 18-20psi before they're at their limits - you'll want to watch your injector duty cycles and a/f ratios closely as you increase boost by 1-2psi increments). Regardless of which direction you go, make sure to do a boost leak check then tune your car every time you make changes.

just to clarify, the stock ecu doesnt care if you have a huge fuel pump and huge injectors, it wont allow you to run more air flow than stock. the stock ecu will see all the extra air being sucked through the mass air flow sensor and will cut fuel.
