So I got the car back finally...

[shaolin]

After them keeping it for nearly two weeks, my alarm is fixed and I got the flash...wow what a difference it makes...I'm just worried if I'm gonna regret flashing it in the future...you know like if I ever upgrade to a T3/T4 turbo or somethin...what do u guys think?

Oh yeah...I have tint now too

I'm sorry man but two weeks?

The flash and the size of the turbo really seem unrelated. Your injectiors (Size) might prove to be a problem. Usually people change their turbo to increase boost. Intercooler, Injectors, ECU should all be modified to accomidate what you are proposing. The T-25 can probably suit your needs until you have done the above mentioned and more to your MSP. A Bigger turbo dosen't mean more power and better performance. It's based more on things like intake manifold pressure and fuel delivery.

Thanks man, I was just thinking far future...you know...I was just worried because I've read that higher boost levels aren't good for a flashed car, but I don't always believe everything I read around here either..

Hey BTW Brian what kinda FMIC are you running? I like Ion's setup, but don't like the idea of cutting...I'm pretty tight with a local shop here in town who told me they would use an XS intercooler, but I'm not sure about that one either...

Two weeks?

It took my mechanic 4 days to source a new engine and put it in for me.

2 of those days were weekend days too.

**** the stealerships.

BOOST

The nice thing about boards like this is that you can learn from others mistakes. I have built my turbo kit from scratch. I chose a Garrett T-25 with a slightly diferent pitch than what comes stock on a MSP. It's a fantastic unit. It just doesn't have the HYPE that the others like the Hybrid have. Don't be afraid to rely on the little T-25. With proper research and smart modifications like a more efficient intercooler and fuel management, that little guy should be able to give you 10 PSI daily. Just remember that your car is running 9.9:1 compression. When you apply a charge of 14.5 PSI or 1 BAR of pressure, your compression ratio would doubles because you have put twice the air in the same cylinder. That will more than likely cause detonation unless everything else is in top knotch shape.

You can probably see the T-25 on My Sig.

It's off a J-Nissan Silvia. It was chosen because it has a 2" inlet and a 2.5" outlet. As it reads, it is a full custom turbo. All the pipes were mandrel bent and welded for this car in the shop that it was for six months last winter. If you want a pic of the engine bay just for s**** and giggles let me know. I designed it myself and used a couple of diferent ideas like where the turbo is in the engine compartment.

Our stock compression is 9.1 - 1 not 9.9 . I think with proper fuel management, 11 psi daily wont be a problem

-B

Wow and I just learned from your mistake...Sorry if I seem like a n00b sometimes guys...the only other turbocharged motor I've ever worked with is a cummings diesel in the Marine Corps trucks...

Fine, 9.1:1. The point is still more or less unchanged.

Ask if you have any questions, even if you think they are dumb.

Hello. I'm wondering why all the people are worried about getting more than 10 lbs. of boost from a T-25. I'm coming from a 1st gen talon on which the stock turbo was a 14B. But the 2nd gens used the T-2small or our T-25s. Stock boost on my talon was about 11 lbs. And I think if i remember right the stock boost on the 2nd gen eclipse was also 11 lbs. with 9.1 :1 compression. Although that was a 420a block from chrysler and not the mitsu 4g63. I used to boost 18 lbs. on my turbo but some of the guys i knew on the second gens used to boost 16 lbs. daily from their T-25. Unless your a don dinero man, you really don't need your turbo to be boosting more than 11 or even 12 especially with the stock internals. In which case the 12 lbs. is easily manageable for the turbo. Feel free to correct me but this is what i remembered. So basically that little hair dryer you have is capable of a lot more than many give it credit for.

The turbo isn't what everyone is worried about, but the T-25 becomes alot less efficient above 10 Psi. It's a small turbo designed for quick response at lower boost. The engine in an EVO has forged internals and other trinkets to allow it to run at 18 psi. Also the compression of 9.1:1 is quite high to start upping the boost above much more than stock MSP. I keep it at 10 Psi daily and 12.5 on a boost controler. Every time I hit that switch, I'm a little paranoid. I guess 10 Psi is like the sound barrier was to Chuck Yeager. It's a magic number it seems.
