well my girls dad just got me the part numbers and the layout of the rsx deal for the fuel pump- it looked very simalar- the email is at my work - tommorow i can post the info- i stayed up about 50 hours over the weekend- man im tired- ill let you guys know- ill also ask josh about the water air intercooler idea see what he has to say bc i when to visit my baby the other day and man there is like no space up front for an intercooler- ill ask him
One of my most recent discoveries is that it's good to have a section of flexible exhaust pipe in betwean the down pipe and the catalytic converter (of course DX, LX, and HX will have to convert their exhaust systems to those of an EX). This is because it's best to isolate the vibrations of the exhaust system from the components of the turbocharger (such as turbine housing, compressor housing, wastegate, down pipe, exhaust manifold, intake piping, and so on...). You can get a section of the flexible exhaust piping from JC Whitney. Look here: STAINLESS STEEL EXHAUST FLEX COUPLER KIT
Also, I found out the approximate maximum boost level that we can run with stock internals. There's a simple rule that you can follow to figure it out. Basically every 3psi of boost is worth 1 compression point. For example, an LX has 9.5:1 compression and an EX has 9.9:1 compression. The most compression that I've seen in a production car is around 14.1:1 - 14.3:1. I don't think that we could even run this high, but let's say that a head gasket that sealed everything in a lot better was all it took for us to be able to run this amount of compression. Therefore the LX could run about 11 - 12 psi and the EX could run about 10 - 11 psi.
If you were to get lower compression pistons, then the lowest that you could get and still make the engine run decent is about 8.1:1 compression ratio. With this new setup the maximum boost that you could run would be about 18 psi.
I'm not supremely confident in these calculations, but I think they're good approximations. Maybe that rule that I found changes the higher you go? I don't know, but I'm going buy these numbers till I find something else. Maybe that's why HKS chose the T28? It also depends on what kind of compressor and turbine wheel they have on that thing; I wonder what the maximum boost rating of their setup is?
OK GUYS- IM GOING AWAY THIS WEEKEND AND MONDAY I HAVE OFF- ON MONDAY MY CAR GOES TO THE SHOP TO GET THE MANIFOLD MADE UP- PICS WILL BE HERE SOON- STAY POSTED- ILL BRING UP THE CONCERNS AND IDEAS YOU GUYSA HAVE COME UP WITH AS WELL- THANX
alright this is my first post one with the elictric (spelling sucks) system we got in these cars would we need to go with a iridium spark plugs and some bigger whatever those things are called on top of our spark plugs (think its a coil) another thing where is the coil getting the power from and would that need to get upgraded and sec could you swap out the radiator on our civ with one from a 6th gen si and than get the intercooler for a 6th gen si that would fit right there so you wouldnt gain that much pds. always makes a diff also with the plumbing would it be better to go with stock or go with more free flowing and i know you need back pressure and another thing about the spool up you know you dont want it to spool up at low rpm due to the fact that are cars run such high rpms i think there is something wrong with mine does all yalls ex standards run at 4 grand at 80 or is mine screwed up or something i also found a program that can be integrated into a computer that can run the turbo and tha fuel system and tell you whats going on in the car sorta like the fast and the furious crap but i dont remeber where i found it will look at work we have all kinds of cool stuff for computers at dell and i know someone that works on cars and does stuff with the computers up there so i will have a talk with him and see what he says about the whole thing
one more question for yall what about bypassing the turbo when driving on the road like on trips because most turbos spool up around 3 grand right and mine runs 4 grand at 80 and if thats the case than i am screwing my gas mileage up the hole
First, please good god use a period. You obviously are educated, so use it. I just got headache from reading your post. I will now try to answer all of your concerns, but it seems that you do not know too much about turbos and thus you need to do some research before you even consider if they are gith for you.
1. About the electrical system: It depends. If you are wanting to run alot more boost, that is a no brainer. Yes, it is also a smart choice to upgrade the spark plugs to colder ones with a slightly smaller gap. Yes, those are coils above the spark plugs, and yes, they can too be upgraded.
2. We have no idea as to this point if anything besides the stock fuel pump is interchangeable with the 6th gens. I am currently spending most of my freetime researching this avenue. I, for one, am more interested in what components from the 6th gen fuel system we can swap out. If there are any, instead we can swap out to aftermarket products that are made for the 6th gens. No, an intercooler from a 6th gen will not fit, because are engine bay is approximately a foot shorter in length than the 6th gens.
3. With your plumbing question, you did not specify what you are refering to. I will make the assumption you are talking about the exhaust. Yes, you will definitely need to upgrade the exhaust to handle the extra flow that will be coming from the engine.
4. Turbo spool up at low RPM: This is where I do no think you are very literate about turbos. The only thing I can think of that would cause your thinking of this is that many large turbos have what is called turbo lag, where as the exhaust gasses are not suffice enough to turn the weight of the turbine because it is extremely large. This is called lag. Lag isn't a bad thing, but for a daily driven vehicle it sucks. Unless you plan to upgrade the bottom end, your engine will not be able to handle the boost that is created by large turbos, resulting in such lag.
5. Yes, 4k is perfectly normal when going 80 mph. Please do a search on this next time.
6. The program you refer to varies. There are many, many kinds of engine management systems, which is what you are refering to, some are stand alone units (like in TF&TF, BTW please do not refer to this movie for any kind of technical knowledge nor quote anything from it, you will be severely flamed from our members, including me. You are new so I am not going to do it, for now!) and others are known as piggy back units.
7. Yes, please refer to a shop, one that doesn't just sell Altezza lights and LED washers, for they will more than likely become a valuable resource for you.
8. Bypassing the turbo: If you bought a boost controller, you would have the ability to lower how much boost, up to a point (I will explain so please wait), but with any kind of power adding devices, you will lose gas mileage. Not all turbos are the same. A relatively small turbo, like a T25 or T28 for example, can drop to around 2psi and still function. Where as a T3/T4, like the one pinkytoe wants to use (which, again, I shall repeat that this is not a very well thought out plan!) lowest boost setting is something around 6-8psi and still work properly.
9. Please, do some research, it is the most valuable tip I can give you. From what it sounds like, start small and learn about the basics of an engine before you try to jump in on a discussion of building a DIY Turbo system.
AzNmiKex215: 10psi. No. The stock fuel system can handle 3-4psi. The internals can handle 6psi (safely) and 8psi max (your engine will not last long at this boost without fortifying the bottom end)
To everyone else that wants to join in. Please read this topic in its entirety before making a reply. Thank you.

For the love of God.............
That's worse than typing in all CAPS.
alright i will tell you right now i dont know much about car turbos i have worked on supertanker turbos and thats it i know they are a bit bigger say 200 times the size but i know its the same idea. and what i was talking about a bypass i mean like running a bypass valve in front of the intake and the exust intake . that way you can completly bypass the turbo and let it just spool down and not even run or is that just stupid. I know i need to do some looking around and the guy i was talking about dont work at a shop he works with me at dell he just knows alot about cars in genral and i was going to talk to him about it and i saw someone say something on here about getting a turbo out of a wrecked eclipse is that a smart idea or is that stupid. and about the exaust what i was saying is that i was always told that you need a good amount of backpressure to get a good spinup on the turbo or supercharger. and if thats so wouldnt putting on a good exaust make it have more free flow and in turn give you a loss of power i am not sure if they make exaust for turbo i would think so. sorry if i ramble i will shut up now i just want to learn alot about this if someone has some web sites they can give me to read up on this it would be great. thanks.
and 10 psi? thats roughly 100 hp ? thats well more then enuff....
