I started this build several months back with the plan of simply boosting the stock KA and shooting for around 200-205hp. So i bought a T25, 450cc DSM Injectors, an External Wastegate (because the internal was missing on the T25 and i got a GREAT deal on it), an OEM Evo VIII FMIC (free), a full gasket set, and replaced the timing chain. However, I've realized recently though that the engine is going to need a pretty good rebuild before it's ready for boost. It's my daily, and my only option of transportation to and from school, so i cant pull the engine out. I have a friend who will sell me a block, and another friend that is giving me most everything else. I figured that since the block would be out and I was going to have to buy all new internals anyway, why not go with forged internals? So after doing some reading and a lot of thinking I've decided to set my goals up around 300hp. I'll probably sell the T25, and maybe the wastegate, and buy a T3. I'll also probably run 10-12 psi, as opposed to my original planned 7 psi. I'll start the pictures from the night I got the car, and go from there....enjoy, and feel free to throw out any suggestions.

i say keep the t25 for the moment stay low boost get used to working on it tune it tune it tune it, almost any one can bolt a turbo together, but tuning makes all the diffence in the world many times u dont need a bigger turbo, just better tuning

Tuning is important, but starting with a turbo that's far to small for the motor is always a bad idea.

very aware. That's why I'll be upgrading sometime this week, and I will NOT be skimping where tuning is concerned
