Well guys today I present you my 2012 G25 which is in my opinion the most attention to detail paid for a G25 out there. But my question is, what else can I do for performance? i know i screwed myself up getting the 2.5 instead of the 3.7 but my credit sucked

My G25 should be hitting 230HP at least (an improvement from the 218hp) but want more of a kick out of, at least reach a far 300hp.
also could any G37 engine parts fit my car, for example; headers, oil cooling kits, test pipes, y pipes, clutches, flywheels, pistons, etc.

I really want to improve my performance and was looking towards the UpRev ECU tuning but was wondering if my car would be compatible? I really want to do the ECU tune because of the estimated 25-30hp increase it brings.

Mod List:
1. Injen Dual Ram Intake
2. Resonator Delete
3. 19" Enkei Coupe Wheels (Hankook Ventus V12 Evo tires)
4. Tein S-Tech Springs
5. Grounding Kit
6. LED Interior and Exterior
7. Tail Light and Reverse Lights Overlay

and some pictures

 

Even after spending more money on mods than the price difference between a G37 and G25, you will still not be close to the power of a G37. If you really want to get close to 330 hp, I would save all your mod money and trade it for a 37. It would save you money and headache in the long run.

 

Or you can possibly inquirer GTM for a forced induction system for your model. I have a good feeling that their current SC system may fit your model.

 

Yeah I know you are right, but I have a lease going and I want to wait at least a year until I try and finish my contract early and taking another off the lot. I have talked to reliable salesmen and they just told me to wait to have the car a full year and then returning and will hopefully only have to pay taxes to take a 37 off the lot. I already found a 2013 G37 S sedan with everything on it, even a 6 speed of the same price as the regular 37 journey (the non navigation model)

 

Yeah but I don't really want to throw 6-7k at gaining the same power on a G37 when I can get a G37 and throw those 6-7k and have even way more power. But if GTM tells me they will design one specifically for my engine and not charge me just like Injen didn't, I wouldn't mind lending them my car for a couple of weeks or so.

 

You want that power? Go twin turbo and you will see 400

 

Hey, never hurt to ask them and they're right around the corner from you. Sam@GTM is a very reasonable person and if he thinks there's a market for your model there's a really good chance he will do it with a discount however I really do not think there's a big market for your model.

Since it's a leased car I'd say skip the forced induction.

 

Its a good idea and would think of doing it if the G25 was not discontinued starting this year. I suppose they will go for a G25 with a 4cylinder turbo engine instead. But who knows since the car is less expensive more people would pick it up and want to start tuning it like crazy.

I know the InJen Intakes for the 25 are a big hit but I don't know about a 6k forced induction system.

I have thought of keeping the car since I am not really a racer but I am one of those guys that whenever I feel an adrenaline rush I can step on the gas and know I am going somewhere haha so I kinda prefer just getting a 370 or a 37.

 

Hey man, know this post is old, but do you still have your G25? If so, did you increase HP much?
Thanks
