Who here was getting all the parts for his turbo together? I'm doing the same and need some help and info. Thanks.

Moocow currently has his car in the shop getting a custom turbo installed.

I believe Grey is in the process or researching a bunch of stuff to put a turbo in his car by himself.

There are a few others that have "claimed" they are getting a turbo, but those are the only 2 I trust right now.

Well, make way, cause I'm starting to gather up the parts I need to put a turbo in myself. My goal is to keep the price under $1000 (with used turbo, or $1500 with new turbo). Only problem is I'll only be runnning about 3 psi until someone comes up with a solution to the Fuel Delivery System. Oh, I also contacted Golden Eagle Mfg. and they quoted me about $1300 for a bore & hone, block sleeving, and a set of ARIAS pistons. Portflow charges about $900 for a port & polish on the head. I'm looking at about $3500 to crank out some serious power (P&P, sleeves, pistons, bore, and turbo). I'll keep you guys posted.

Oh, and by the way, anyone here looking to sell their non-VTEC D17A1?

Damn, 3 psi, dont put too much in there now.

Yeah, I'm still reading up on the subject. I want to have all of the right components and make sure that they work together properly before I start buying stuff. I'll take care of some of the simpler things first. Like oil pressure and temperature guages. That will be first and I can use them right away. Then I'll tap the oil pan and add on an oil cooler and a line to feed the turbo. I'll cap off the line and tape it to the chassis, to use later when I install the turbo. It's funny 'cause I'll need to install all this stuff, but I won't be able to install all of it since I want to be able to drive the car.

I'll probably be able to install the exhaust manifold, the turbocharger, and the downpipe without installing anything else (maybe the wastegate too). Just sort of let the turbo spool up as I drive. Then create all the piping for the intake and the intercooler. That will be difficult; I still don't know how I will make all the bends. I wonder what psi the rubber pipe connectors can withstand? I have to find this out as well. Welding will definately withstand higher boost pressures, but I don't know if I'll ever get that high?

Anyway, ask away... I know some stuff, not everything though.

You don't, thats for another project I have in mind.

Grey, I'm sure that all the charge pipes can be made with the piping from JC Whitney and some measuring/cutting. Do you plan on going intercooled, or non-intercooled?

Yeah, you don't, but I'll be able to run higher boost pressures with my stock internals than an EX would since an LX has lower compression than an EX. I'll also produce more horsepower than an EX would with a turbo. This is mostly due to the fact that the EX can not go above a certain psi without changing the internals of the engine. An LX, on the otherhand, can go beyond that psi and still not change the internals. In theory if you did not have to change the internals of an engine, then the EX would produce more power with a certain boost level than the LX since it compresses the fuel more than the LX. Anyway...

Why, what kind of piping do they have at JC Whitney? I was looking at McMaster.com for piping. Ah... I went to www.jcwhitney.com and I think I found it. Mandrel-bent aluminized tubing for exhaust systems. Is that what you had in mind? They have stainless tubing as well, it's just more expensive. What about the aluminized stuff, do you think that you could polish the aluminum coating to a mirror shine, or would you eat through the aluminum?

I plan on installing an intercooler. Maybe at first I'll be able to run without an intercooler at lower boost pressures. After that gets boring and I want more power, then I'll install an intercooler.

Again, you have to deal with the fact that we can't get enough fuel to the engine. I wish I knew somedoby with a Civic that we could experiment on. [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

I do however see the RSX fuel thing happening - it makes more sense than anything else to me. I think I'll take a trip to the junkyard and see if I can find an RSX gas tank laying around.

I think you should have no problem with the aluminized piping (but stainless would be better because of strength, heat conductivity, etc, but it's all up to you).

What kind of injectors do you plan on using Grey?

 
Rep Power: 419

The fuel delivery issue isn't that big a deal. At first I'll run low boost levels if I haven't upgraded anything having to do with fuel delivery yet. I'll clue in on HKS's design for the initial boost levels. I'm going to get the RSX fuel pump and fuel pressure regulator. I think they're both in-tank. Maybe a junkyard will have them? Once I have the list of all the parts I need I'll go out and find the best possible price on everything I have in mind.

For higher flow fuel injectors I went to Racing Fuel Injectors - RC Engineering and used their fuel injector flow rate worksheet and it seems like I'll need ones that flow around 200-300 cc/min or 20-30 Lb/Hr. Too many variables though, I'll have to look up other turbocharged civics and see what size injectors they use. My goal is to get the maximum horsepower possible without constantly rebuilding the engine. I'll have to do some more research before I know what this number is.

It all depends on what your ultimate goal is. How much horsepower do you want to produce? What do you have? A VTEC engine or a non-VTEC engine? I think I could get a comfortable 230 horsepower at the crank if I pay attention to all the details. I'll probably be slowly increasing the boost pressure as I start solving all the problems and upgrading certain components.

Remember that upgrading the ignition system is a must as well for higher boost pressures. We'll need to run higher octane too. One thing that I'll do right away is buy spark plugs with a smaller gap than stock.

Grey, do you know what controls the FPR on our cars? If the FPR is controlled by the ECU, that means the ECU will compensate for the larger amount of air and raise the pressure on the FPR so all we would need is a bigger pump. If the FPR won't go up as high as we need it to, we can use the RSX FPR.

I actually don't know myself, but I asked many questions and people who seem to know the answers responded in this thread: CUSTOM TURBO KIT BEING BUILT! NEED INTRESTED PEOPLE

The short answer seems to be that the fuel pressure remains constant and is kept at a certain level by the Fuel Pressure Regulator which is in the gas tank along with the fuel pump and the fuel filter. The ECU adjusts the amount of fuel fed into the combustion chamber by adjusting the fuel injector's pulse width (whatever the hell that means). I thought that we had an FPR that was controlled by the ECU as well, but I guess we don't? The way to add more fuel is to have a fuel management system like the S-AFC.

I need to do more research before I'm positive that this is the case though. I also need to know how the entire fuel system functions.

Grey, the injector pulse width just refers to how long the injector is spraying for. A longer width means it's spraying for a longer period of time.

Sorry to but-in guys......but we dont have a FPR, right???

nevermind----in the tank

reason being-- there are no zex kits for our car.......they require a FPR......we just cant get to ours?

<< Grey, the injector pulse width just refers to how long the injector is spraying for. A longer width means it's spraying for a longer period of time. >>



Ah, I see. Then why won't just upgrading the injectors to ones with a higher flow rate and upgrading the fuel pump (maybe the whole in-tank unit) solve the whole fuel delivery problem? The ECU will open them for a certain amount of time and it'll think that it's spraying an X amount when in reality it's spraying an X * Y amount. Know what I mean? Am I missing something?

trevor: We could get to ours, it's in the gas tank. You have to take out your rear seats and open this little access port to get to it. What do the ZEX kits need? Do they hook up to an electronic FPR? One that adjusts the fuel pressure? Our cars have an FPR that only caps the fuel pressure and keeps it steady. At least that is what people say.
