These motors are probably 15-20k once they reach the track. Just a offhand guess. As my son has spent 13k on a street motor with no tranny mods. Just motor, ported heads, bigger cams, 100mm bore, open source tuning with datalogging and utec piggyback, bigger injectors, bigger fuel pump, bigger oil pump, front mount ic, 8qt oil pan, true cold air intake and a 30r rotated turbo at 26 psi. Conservative tune about 425awhp. Also no water or alcohol injection yet.

A 2.0 wrx converted to a 2.5 shortblock is called a hybrid on nasioc. Not a real hotrod suby just a upgrade when the rod spins usually. The characteristics of the 2.5 with the 2.0 heads, cams and turbo is that it will not have enough breathing at 6k and above. The fact that it is in a lighter car might help a little when it's in the 914, but it will never have the higher rpm power of a true 2.5 sti. The sti has bigger cams and a bigger turbo to go along with the avcs cam control that gives a broader torque band especially at lower rpms. Even sti's with aftermarket cams run out of steam at high rpm without getting bigger valves and porting. The wrx 2.0 is pretty well a balanced combination that is reliable at the stock power levels until a 20 year old starts pushing it. It will live pretty well with a more mature user with mild upgrades up to about 260 awd hp on 91 octane. Adding the 2.5 shortblock gives it more low end torque and a little more hp. the noticeable improvement is usually because it's a new lower end with better ring seal and more displacement. Subys use oil when they are pushed hard and are boosted more. When they get low on oil the rods spin.

There is alot of trueth spoken here. Very well said... However I am months away from 40 and I popped mine (faulty radiator core). I have TONS of power left on tap just with adjusting the throttle to open 100%. My original point is this. You do not need a "Hot Rod Suby" to compare apples to apples. A real "Hot Rod Suby" will produce 800+ horsepower and will cost the numbers that were eluded to in the beginning of the thread. I wanted to show everyone that you don't need to spend huge money to get huge results. I no way did I ever say my engine combo is a "hot rod suby" in fact, just the opposite. You are correct as to the term "hybrid" applying to my engine's setup and that is exactly what I have. I didn't want to use the hybrid term in the 914world forum because we all associate that with a teener w/o a Porsche engine, not with a STI engine with WRX goodies.

Reading what people say you will expierance with a hybrid setup is a good place to start, but not exactly the same as having one and driving it yourself. It does start to fall on it's face due to the smaller turbo, but you are shitting your pants bye then so it really doesn't matter. Once again, if you still want more, throw a STI turbo on it, still not enough? Aftermarket tunable ECU, now you have atleast 500 horspower. I will be happy to let you drive my car and if it is not enough for you AS IS with 50% throttle opening then I digress. The last guys I took for a spin build 800 plus horsepower Subies that are all over the tuner rags and they were/are in disbelief what my little teener is doing now with only slightly over half throttle... You drive it, you be the judge.
