What should I spend my money on

[whaap]

A saying that I've relied on many times: When in doubt, do nothing.

[JoeBoxer]

Full exhaust (I like Motiv, Milltek, and MXP products, Perrin is great too)
FA20Club tune (great for auto trans cars)
HID's
18" Work Kiwami(GT Silver finish) or XD9 (bronze finish) with tires
very mild drop spring (Racecomp or the STi springs)

save the rest until you decide on supercharger/turbo kit

nitrous? if youre worried about money being spent a lot, nitrous would probably blow this engine up unless it was forged to the hilt..

I threw nitrous around loosely. I meant a very conservative shot, 75 max. I'm new to Subaru engines, does even that require forging internals?

How exactly do you figure this about nitrous? n2o is the same as any other power adder like a turbo or a sc. In fact its actually safer than many aftermarket turbo kits provided you dont shoot a 700shot.

Allow me to introduce you to some knowledge. A turbo kit boosting 7psi.. 7psi is compressing the air, which means its introducing more oxygen into the combustion chamber, which means more fuel can be injected, more burn, etc etc more power.

Nitrous is n2o, in the combustion chamber, the nitrogen bond is broken leaving nitrogen and oxygen. This means theres more oxygen, which means more fuel, you get the idea. The added bonus is that nitrogen in its free floating form, acts as a buffer to prevent detonation. something you don't get with any other form. Even shell advertises this fact with their "nitrogen enriched gasoline". A properly installed 50shot of nitrous will always be safer than boosting an na motor. With this engine, id aim toward a 50 wet shot, direct port injection. Nitrous is only used when you want to use it, you cant turn off a turbo.

AirRaid has a nitrous kit on their demo car but not sure if it's functional, i would do a 50hp shot, maybe 60 at most but still would be scared of it.

yeah dont listen to these people. until you know what the car needs, it doesnt need anything. spend that money on track days or driver education. with enough proper seat time you will find out what you need. toyota/subaru spent too much time making the car what it is. i would advise against unraveling their work so blindly.

He came here asking for suggestions, he must think it needs something. Enough of us have modded the car to know what you can get good results out of, my recommendations were based on personal experience and research.

TRD SC, better tires, coilovers.

i didnt mean that to sound like i was discrediting anyone. it is clear he doesnt know what he wants apart from dumping 10k into the car. what is right for other people might not work for him.

all i was trying to say is that if it aint broke, dont fix it. take some time and find out what you want. not to mention that is probably worth noting that time behind the wheel is absolutely the most cost effective way to go faster.

I don't want to clutter the thread but he did mention wanting exhaust and wheels and tires. Since he has the Five Axis kit already he really does need the wheels and tires to complete the look, hopefully we can provide him some assistance finding what he wants instead of just saying don't do anything if you don't know what to buy.

The question was what we would spend our money on, not the most cost effective way to go faster.

nice that you are knowledgeable sir. i know how this shtuff works but i just kind of dont see any point introducing n2o to an 8-6 i mean it is a circuit car. if you really wanted a drag machine with nitrous id go for something with a V8. the turbo would be more suitable for the 8-6 since youll need it when you exit a corner. and i was thinking some one would want a big shot of nitrous since the car doesnt have alot of power and if youre trying to beat up a more powerful car id think 50 wouldnt be enough that would make the car actively running 250-265 hp correct me if im wrong.

ah gotcha. well in reality you dont need to forge the internals until you make big power. since the engine has a forged crank shaft, fracture forged rods and sodium filled valve which is insane , from factory.

im not sure what the tolerance of these internals are havent really looked into the maximum power and torque the rods and pistons can take from stock yet.

id figure a ball park of a solid reliable 400whp before they start to let go. i may be low balling this though. ej257 (04-05 wrx sti) 2.5 liter can take around 500 before the rods start to go, thats what EFi Logics claims.

nitrous makes gobs more torque than hp, a 50shot would be somewhere near 70-100 additional tq. Thats what your looking for on the outside of a turn, getting back up to speed as fast as possible. hp will help you on the back straight, but not as much as higher torque will coming out of the bends. Most circuits/series wont allow nitrous though. I primarily use nitrous on hill-climbs and drift cars. Nitrous is basically like the KERS system they use in f1, same thing almost, it just doesnt have to charge up.
