Are you sure ut is a T25??
this is avery small Turbo used on teh Ford cosworth RS or nissan Z300
This is maller than your k27 that you have.
I doubt they can make 400 HP with this or with another Turbo out of the 2.5 L engine unless they run tons of boost.
I never saw a 2.5 L with a stock DME over 350 HP for 400 you need a 2.8 at least and a lot of boost.

Paul,
Be careful with this mod. The GT25 cannot be rebuilt ! Garett will not release the bearing cartridge as a spare part, which means you have to buy a new turbo. Also the technodyne mod does not include the electric water pump which without it will reduce the reliability of the turbo ! The entire exhaust system requires a mod so no other turbo will ever bolt up to it. I would estimate this mod will cost you over 6k for 100 horsepower gain from where you are. You have to run 110 octane to boost to 20 psi to get to those levels anyway and on pump gas you are exactly where you are now anyway. So if you have tons of bucks to spend on a mod that has the potential to reduce your reliability for a car that is worth 10k go for it. But think twice. <img src="confused.gif" border="0">

as a mom amerocan I must say what I think. You always say a xxx$ suit or a xxx$ car or what ever. It is not the money that is worth it is teh car it self!!
who cares if a F1 car that cost only 1 Million wins and teh other that cost 20 Million lose? what is better?
You should compare a 400 HP car with a 400 HP car. the one who paid $80000 is stupid as he has the same power as the other guy that pay only $10000.
I would go for it! Mr Bloomberg! you have a powerfull car and you can not compare a 400 HP 951 with a 217 HP 951! $10000 are for stock car that have nothing else extra! A good race car (or street car) cost much more. If you don't believe me look at teh adds for good 951s and where can you find a 400 HP for $10000? everybody would take all this stuf out and use it again or sell it and stills ell teh car for $10000.
Im spent $40000 for my car 12 years ago and none knows how much more to make it fast. I never looked back and I would do it again! It is teh fun that count not teh money you spent! You can aslo spent much more money on a Boxster or on another car and you have not even half fun or power!
You have to make adecision. You wnat 400 HP. How can you get them cheap? there is no cheaper way on a high HP Porsche than to buy and tune a 951.
It is not the $1000 suit who makes somebody imporant it is teh person in it!
It is not the money that the car cost, it is the power and teh handling of teh car.
Of course posers thing different and they care more for show and less for powerfull cars but we are not posers and therefore we want powerfull cars but not pay thousands of dollars since we can have the same for much cheaper. Otherwise buy a $1000 car and be happy with itb till it brakes. Then buy anotehr one! I hope you understand what I mean.

Paul,
Hey if you are happy with 6k for 80hp so am I. I am more concerned for your long term reliability. Any tuner can build HP thats the easy part. The hard part is to build reliable HP that goes the distance. If something goes kaboom your 6k investment will be much higher and I dont think you will be as happy then. What ever you decide I support you 100% But for 6k I would opt to make the engine stronger and do a engine management system. That provies with better reliability and greater HP potential. Good Luck let us know what you decide.

TURBOGUY,
I appreciate that! I was thinking about stand alone engine management today. I am concerned about engine reliability but at this point I am not really going to be pushing the car that hard/long. I realize the tuning potential and what happens if the a/f goes lean. With engine mgmt. systems if a injector fails while on boost does it shut the system down or how does it protect the system if it goes lean?KABOOM!!
regards,
Paul

Paul,
The more spendy engine management systems have the smarts to retard boost under lean conditions. If an injector fails it would be a catastrophic condition that happens so quickly I dont know if any system can react fast enough to remedy the situation and actually prevent a kaboom. If you can build it strong from the engine on out and keep a/f to 12.6 and keep the boost at a point to ensure zero detonation with high octane then you have a recipe for performance, upgradablility and reliability. If you go this route I would seriously consider replacing the stock oil cooler with a much larger one.
