Talking What parts do I need to add a turbo?

I wanna add a turbo to my 2000 Subaru Legacy GT Limited. Im currently running a Bomz Racing Intake which adds only like 10 HP or so. I've decided that I wanna go turbo kit in the upcoming months. Could someone please list ALL the parts I would need to buy to install the kit. (I wanna make my own kit, not buy one) Also, what about ECU? Thanks a bunch! (I was thinking big turbo, WRX intercooler, etc..)

Click on the link above for all the components for my turbo project. PHATsuby also has his turbocharged, and he went a slightly different route... Similar results though.

Enjoy

Is your car Automatic or Manual?

Since your car is a 5 speed, the Link ECu that comes with the kit will not work with your car.

You can get a Haltech E6X or Autronic SMC for engine management.

As for the turbo kit, go get what PHATsuby has, it's a Ludespeedkit.

If you get the Autronic ECU, both PHATsuby and I can help you, cause that's what we are using.

Besides engine managament, what else do i need besides intercooler, interecooler mount, and the turbo?


Because my friend has stock WRX intercooler he might sell to me for cheap, then i can customize whatever turbo i wanan throw in there, and then work my way from there....

There's a whole forum dedicated to answering your questions. It's the Aftermarket Forced Induction forum.

Don't want to be rude, but, really, they have all the answers.

99% of parts that fit onto an Impreza 2.5 RS will also work on a Legacy.

Enjoy!

Thats fine, just keep it here we are the ones to be asking anyways cause we have the Legacies! it maybe true that 99% will fit, but i seemed to run into that 1% alot

if you have a wrx intercooler it needs to be modified to work with the ludespeed kit, contact Tom at ludespeed and he can tell you more about that. if you want to go that route that is.

besides what you listed, you need a full exhaust(new headers arent really necessary but can get them if you have the cash), uppipe, downpipe, cat back(at least 2.5" is desired) you need a blow off valve, wastegate and all the various hardware and hoses. there is more i am forgetting for sure. thats why it is easiest to get a kit. in my opinion, however Joe does make a ALOT more power than me But he is smarter too. haha.

Right, Ben. But I just think he needs to go over to AFI and read up a whole lot.

Then, when he understands all that is involved with a turbo kit, come back in here with Legacy-specific questions.

I just emailed SPO Motorsports, the vender of that kit, and they said that the Engine Mangament software that comes with it WILL work for the manual transmission, in fact its made to, wont work with an auto he said..

If you feel confident that it will work, make sure they stand behind it. Because I know for a fact that our "manual" tranny Legacy's have crank and cam trigger setup that come on the WRX's.

The link is configured to work with a 6 position crank trigger.

It's gonna be an expensive experiment if it doesn't work.

Good luck, keep us informed on how you make out.

yea, call him up and say "how many teeth do i have on my crank sensor for my legacy?"

if he says "6, just like an old impreza" or "its the same as an impreza" then you should promptly hang up the phone and not ask them anymore questions regarding what you should do for the legacy, because unfortunately most are just going to say it works so that they can sell something.

so just beware, WE have done this(Joe and I), they HAVE NOT on a legacy of our model years if any legacies at all.

just trying to help

Ben

also the fact they they said it wont work with an auto, right there you know they have no clue what they are saying.

How much power can the 2000 automatic transmission handle? would it require a rebuild if upgraded to a turbo?

i will let you know in about 5 days, it has been said that the 4EAT can handle about 300 crank hp, i would guess that i am in the 250-275 range. But even with that much increase the tranny couldnt handle the extra power, so i sent out my valve body and torque converter to get modified, and we should have them back and reinstalled tuesday hopefully, so the tranny definitely needs to be upgraded to handle the power, and hopefully this will be enough, we are also going to try a little experiment with it as well, we are going to put in a switch that will drop the resistor once i hit boost that way the transmission will go to full line pressure, hopefully that will help as well.

but stay tuned

ideally i would have liked a full build but i dont have the income to drop 4500 dollars for it right now, so i am hoping this will at least last me till summer

What about one of these? What do they do for engine management?

i think i already told you this but i more or less have a ludespeed kit on my car.

the stage 2 uses a split second voltage clamp and a RRFPR to manage the engine, and a J&S safeguard is used to control detonation. this type of management is far from ideal. the reason is that basically the voltage clamp is just tricking the stock ecu so that it doesnt see boost, and the rising rate fuel pressure regulator is raising fuel pressure based on boost, and this is a set ratio, so you cant fine tune at all. And i never really noticed before but i guess it also is just using the factory timing curve which i think would be dangerous, and the J&S just constantly corrects it when it detects detonation.

truthfully, turbocharging is not a cheap thing to do, especially if you want to do it right the first time. my advice would be to save your money until you can afford the proper engine management(like the autronic, haltech, or other compatible PEMS). this will save you a lot of trouble in the long run, and if tuned properly you can achieve much horsepower than just using piggy backs.

it has been said(and i guess i will repeat ) whatever you spend on turboing your car you should have an extra 1000 dollars at least for some unexpected problems.

i dont mean to scare you, im not trying to, because turbo is definitely worth it but i just wanted to let you know what you are getting into. but with that being said i am here to help all the way

Well, I don't know how long it will take for them to complete it, but Cobb is working on a turbo kit right now. It will also include an ECU reflash to accomodate for the turbo.

The newer Legacies also do not have a hood scoop, the Cobb setup will not be running a TMI to accomodate for this. It is going to use an air-water intercooler. I wouldn't go through all the effort of getting a hood scoop for a '00+ Legacy just to use a WRX TMI which isn't very good anyway.

If the Cobb kit comes out in a reasonable amount of time I think I might go ahead and do it. If it takes much longer (quite possible) I'll just forget about it and start saving for a next gen Legacy GT Turbo.
