Question Have a turbo, now what do I do?

OK, I found a stock WRX turbo on eBay that was removed after 8k miles for an upgrade, so this turbo is like new almost. So I threw a really low bid on it, and I guess it slipped through the cracks, and now I have a WRX turbo and no idea what to do with it! Anybody know of someplace that sells up/down pipes that work with the stock RS header, or do I need to get that custom made? I have no friggin' idea what I'm doing, as I thought for sure I would get badly outbid! Larry, if you read this, would those up/down pipes you sell as a part of your VF22 kit work for me, and if so, do you sell that stuff seperately? Somebody, help, I have never dealt with anything turbo'd before, let alone building up a kit! Is this really worth persuing?

Sweet, thanks, I'll do that! Man, if I can build a low-pressure system (~5psi) for cheap, I would be the happiest boy in the world!

My current turbo kit (less turbo, cooling lines and oil pan) may be for sale very soon - your TD04 will fit it. Basically this is the up/downpipe, intercooler, intake, pipe to intercooler, and forge BOV recirc type.

I am installing a ScoobyRacing turbo kit like the one we sell off our website. email me and I will give you details. I have one buyer already interested in it, but he might pass.

And after you get the up and down pipes you have to:

-Get a new oil pan or tap your old one for an oil return line

-Get a new fuel pump

-Get a RRFPR

-buy all the fittings for the turbo

-Buy a mount for the turbo

-Find some mandrel bent tubing to route to the turbo and to the manifold

-buy a new filter

-Buy an intercooler (if you want to give the engine a chance to last)

-BOV

-Wastegate

-Zenier Diode

-and a couple other things

you are almost there!

There is a reason turbo kits are so expensive. They are not as cheap to make as you would think. Sorry but you have quite a few more dollars to spend

Yeah, I know I have a long ways to go, and some bucks to spend, before I have a working turbo kit. But I got this turbo so cheap, I figured I would at least look into how much it would run to put a kit together, and I knew that up/down pipes where a good place to start. I've never dealt with anything turbo'd, so this is all new territory to me. I plan on getting a proECM, and that has the voltage clamp on it, and a RRFPR is a given with turbos, but all the rest of the stuff, I'm clueless about. Teach me, I am a blank canvas!

If you don;t mind me asking, what did you pay for the turbo?

You can save some money by not getting an external wastegate, since the wrx turbo have an internal wastegate.

Get a Vortech FMU from some Honda guy for a RRFPR and an intank fuel pump, use the internal wastegate, pickup Zaidallas old spearco intercooler, make some piping to feed the intercooler, Follow the suggestions for the Up/Down Pipes, and the PROECM will do the trick, Some Gauges and you can make it happen...Money and Time is all it takes

$192.50, and I'm still waiting to here back what the shipping is going to be. Sounded like a good price to me, especially for something that can reach 1 bar. I'm only looking for about 5 psi, so I'll have room for growth if I do decide how to persue this.

Assuming I am reading the compressor maps correctly, it seems like a stock WRX turbo is a terrible turbo to use for a larger displacement/low boost application. Looks like it will drop below 60% efficiency long before you reach redline.

I'd originally considered using a WRX turbo for my car since they're so inexpensive. But I'm pretty sure it's too small for even my 2.2 liter motor.

Anyone else get the same impression from looking at the compressor maps? My estimates on cfm at redline may be way off.

I believe it will work great for a low boost 6 psi kit

Look at the guys with little legacy turbo's at 6 psi, they pull to redline...

the TD04 is too small for the WRX let alone the 2.5rs.... but it is a GREAT place to start from. plenty of bolt on that will fit in its place and its cheap to start with.

That's what I was thinking. I'm not looking to build a monster or anything, as I don't street race, have never taken it to the strip, and have only run in 3 rally-x's. I just want more power, and if I put the TD04H in, I can always upgrade later if decide I do need a monster. But right now, I'll be happy with 5 psi. Don't want to blow my tranny right away, and I still have 2 years left on my warranty!

if you don't get an external wastegate you'll probably be running the same thing I will be at.. 8-9 psi unless you find a place to get another wastegate.

I'm not doubting that it will pull to redline. I'm just saying that, based on what I read from the compressor maps, it's going to be adding far more heat than it should. It's a much worse condition than the WRX.

The way I see it...

The WRX turbo can make 280hp easy with Stage 0 kit, and maybe 300-320hp if you are lucky and the weather is right.

So, 6 psi on a 2.5L at 250hp isn't unreasonable for the TD04.

Default Yeah but...

Any internal combustion engine will benefit from turbocharging and a like-new TD04 will be excellent for a nice power boost without stressing too much over maps and peak effieciency...Even in the 10:1 EJ25...Just add enough fuel to keep the piston and combustion chamber cool...The key to keeping your engine reliable is to avoid detonation at all costs...It can be done on a budget...

Well, I've got lines on the TD04, a Vortech 6:1 FMU, and possibly some up/down pipes. And I'll be getting a proECM, which has a voltage clamp. Guess I'll need an external wastegate to keep the boost down around 5 psi, too, so I better start looking. What kind of intercooler size should I look for, and should I try to find a top-mount, or would it be easier to get a front-mount? And what about an old Subaru air-water IC? Any good? Dang, starting on something like this makes me realize just how little I know about turboing a car And thank for all the input guys, I need all the help I can get!

i too have been thinking about going turbo this way. i have some legacy turbos kicking around and i am torn between keeping them or selling them and saving up for something else.

anyhoo, hondah8r, you're on the right track! i don't want to be a jerk but a book like bell's would be really helpful. it will clear up some nomenclature and help put things into perspective. if i can find my copy i'd be willing to loan it to you. we aren't too far away (relatively).

the nice thing about going along this upgrade path is that you can do it slowly and buy only the pieces that you really want (ie-turbos, wastegates, BOV's, electronics, etc). then you won't have to buy things twice.

does anyone know what other turbos share the flange design with the WRX's TD04? that would be interesting to find out. to be honest, subachad at www.uniquemotorsports.com could probably add any flange be it garrett, IHI, et al to his up and downpipes with little problem. the only drawback to his products is that there isn't a provision for an external wastegate...yet. i've spoken with him and he said that it could be done.

good luck with your project and keep us updated.

IHI turbos share the same flanges...

there are others aswell made/distributed by APS, PE and a few other companies
I think Mitsu had a few other turbos aswell like a TD05 that was on the older WRX's

racerwad, what book are you talking about? Do you know the title? And don't worry, I'll keep everyone updated on what's going on. As of right now, still waiting to here what the shippng on the turbo will be, but I do have a Vortech 6:1 FMU coming for a pretty god deal.

Now, with the 5 psi I plan on running, is an intercooler really necessary? I know it's not with a supercharger, but SC's don't get heated by the exhaust like a turbo does. I know an IC would be the best way to go, but if it's not needed right now, I might hold off on getting one right now. Of course, it's not like I'm planning on having this thing up and running any time soon, I want to do it right the first time.
