My lord. I have NEVER read a thread with more bullshit and lack of knowledge in my entire life.
Platinum_Civic- disregard just about EVERYTHING in this thread, as listening to it will lead you to one end- a blown motor.
Let's start from the top.
Turbo vs super. In all applications other than autoX, turbo is the way to go. period.
since you'd already decided on a greddy kit, lets take it from there.
The greddy kit probably won't come with an intercooler or a Blow off valve. I highly recommend you get these two things. PWR makes some kick-ass 'coolers at great prices. blitz DD is a good BOV, as is the greddy type S.
How does a turbo work? one guy says you save gas. dude- off yourself from threads that you obviously have not a ****ing clue what you are talking about.
A turbo has 2 sides. A compressor and a turbine. the turbo manifold (no- not a header as moron #2 stated) attaches like a normal header would, but it has a flange for the turbo to be mounted on or a wastegate depending on the actual manifold. Exahust gas coming out of your motor goes down this pipe and spins the turbine wheel and then exits out the tail pipe as usual. the turbine wheel is connected to the compressor wheel by an axel. it is this axel that requires oil for lubrication. The compressor wheel is now turned, and thus COMPRESSES air. it doesn't PUSH. thats a huge misconcetption. what is the by-product of compression? heat. heat sucks. heat leads to detonation. so what do we do? we run this compressed air through the intercooler, to drop the temperature hopefully down to near-ambient temperature. Keep in mind- there is a HUGE difference between air volume and air mass. the air voume is what creates the psi. air mass is what gives you power. Compressed air is more dense, and thus, you can fit more of it for any given area. there's some mathematical formula for it, but thats out of the scope of this post.
What is PSI and why is it over rated?
psi is the amount of air NOT going into the motor. it is measured at the intake manifold. while a little psi helps to get the air in a little faster, its the air mass that gives you power.
example- a t66 is a huge turbo. a t25 is a small turbo found on some stock cars.
a t66 flowing 5 psi will produce 3-6 times the amount of power that a t25 will at 10 psi.
saying - "yo, i wanna b00st my shiz lik 8 psi. Do i need internals?"
not only makes you sound like an idiot, but proves that you don't know dick about turbos, boost, or honda tuning in general.
Platinum_Civic - I'm running out of time for the total explination, so let me get right to your direct question.

What are the FIRST few mods I HAVE to get that the Greddy kit doesn't come with??
|
1- get rid of the "blue box" that the kit comes with. all that thing does is make you run really rich, thus pouring a lot of fuel on the pistons in an attempt to keep them cool, and thus resist detonation. What it really does is suck a shit load of horsepower and doesn't really help you resist detonation. so, sell that or beat it with a bat. do something with it- but don't put it in your car.
2- PWR intercooler. they are cheap, and more efficient than a spearco. if you need help finding one, send me a pm and i can help you locate one for about $300 or so.
3- Blow Off Valve. see above
4- 3" exhaust and a high flow cat with a real 3" center, and depending on your down pipe, probably need a 2 1/2 inlet for that side
5- injectors. i'm not sure what comes with the kit. but if they aren't at least 310's, upgrade to 440s.
6- hondata. the only think thats going to save your motor.
7- dyno tune with a wideband o2. not only will you get more power, you will not blow up if you are tuned properly. i can not stress how important dyno tuning is.
if you have any questions that need real answers, feel free to send me a pm.
