Unhappy

CRAZY KEN, I've been thinking about it... that's about it though, just thinking. I don't have the time or the money to screw with my daily driver like that. I'm not sure if there's a turbo'd Legacy on here. I guess Legacy owners aren't hardcore like those nutty Impreza guys. Of course, if the turbo route were expected, I think most people would think you'd do it first.

I'd say just hang out in the Aftermarket Forced Induction forum. There's enough jedi training floating around in there, I think. Good luck, mon ami.

May the B4 be with you!

Before I drove a WRX, I was convinced that I would go turbo. The way I was going to do it, was to plan a vacation out East, and leave the car with Rallispec for a couple of days. Some $6-$7K later, turbo Legacy.

You CAN do it yourself, but by the time you finish fooling around, coupled with the potential for damage...why not entrust it to someone who knows how to work the mojo?

i've been kicking around the idea for a while, too. afaik, there's only one 95 or newer turbo legacy on this board, syms gt.

my plan would pretty much be like gtguy's. go to rallispec, have them custom build the kit on my car, and then pick it up in a few days with everything running. i'd go with their stage 1 plus a few extras. the legacy is my only car right now and i don't have a place to work on it (live in an apt. building), so getting the car running immediately and reliably without having to fuss around is important.

some things i've been thinking about: what to do for engine management, swapping in an ej22t at the same time, and what if the b4 comes out in 3 years?

Hehe.

Factory Turbo Legacies rule

gtguy is right, find a shop like Rallispec that does it and entrust them to do it right and warranty the work. I know the inner kid in all of us would really dig putting a turbo on an N/A car, but man, it's a PITA to do.

Crazy Ken - It's not as far fetched as it sounds to do a turbo'd Legacy. I had a turbo kit in my GT for awhile, but due to some tranny problems I've had since the car was new, I took it out so the warranty would cover the tranny. SYMS GT is the only other Turbo'd BD5/9 Legacy I know of. So far I've kept the boost bug away from the Legacy L, but soon I maybe putting in either a turbo or S/C into the L. I'll have to wait and see.

Default vroooom psss psss (love the blow off)

Yeah I have recently started looking into this and so far what I have found out is that the 2.5 is capable of handling up to 5psi of boost in the stock state and to go any higher than that you need to at least upgrade to forged pistons as far as the rest Im not sure yet but Ill keep looking and let you know what I find out, let me know if you find out first.

By the way does anyone out there know if there is a carb certified turbo kit for soobs yet? Us cali guys get constantly beat by our smog laws?

thanks,

Hey Ken,

I know exactly where your at. I have been tormented by many of the above ideas. I have been back and forth with ideas of a turbo application on my Leg. Heres my current plan.

Plan A: Continue NA Modding of my current Leg and Buy a B4(like) beast when they come out.

My current DOHC EJ25 has a 2.5" catback, and an intake. My plan for further engine performance is to stay NA. Sigh-there I said it. I am planning to get headers, hi flow cat, and safc. I plan on playing with different intake options to see just how much air I can force down into the TB without more moving parts.

I know its so hard to wait.

When I was turbo happy I watched the troublesome group-buy


from the likes of JC Sports, ASR, Ludespeed, and even Rimmer w\ his SC kit.

My advice to you would be similar to thet above replies. Go to RalliSpec with a hand full of money and a TEC-II. The TEC pretty much takes care of your questions about which turbo timer, boost controller, air/fuel controller, knock sensor, gauges as all of these are built into a nice little box which you can control through your laptop, rather than 16 comfort crushing buttons, dials, and lighted gauges. Ralli Spec will be able to provide you with a turbo designed and tuned for you car with all of the necessary parts and peices including full exhaust and clutch.

As boost levels my goal was around 7-8psi daily on stock internals. I wanted to go with a water spray intercooler since our hood scoops don't create near as much drag as the RSs do. So in turn the scoop probably isn't going to suck in as much air. Your engine also get a nice water cleaning treatment every day.

I recently read an article about the Rotrex Supercharger. If anything I would buy one of these for $1300-$1500 and take it to Ralli SPec and ask them to design a system around it.

Looak about half way down the page at Digital Boys comments.

Oh yeah... been looking... been drooling.

Once I have the car paid off, I can stash away those 'would be' payments towards a turbo. Prolly a Rallispec since its done right. I'd have to go for a B4 hood swap as the MY00+ GTs are sans scoop... and no scoop usually defeats the purpose of the IC.

I may go with a low boost, 3-5lbs, application to start and then add on as I go... IC, Scoop, clutch, etc. As the car ages, I'll feel more comfortable modding it.

For right now, I've got a year or 2 for the payments to end.

Check out Forced Air Technologies in the Links section. The owner, Robert turbo's Legacy's, SVX, and yes RS's. In fact there's a 91 Legacy wagon in there being turbocharged as we speak. I have one of their kits - its excellent, with great fit and finish. Anyway Robert is always willing to talk turbo's. You can call him at 928-632-1251. Not meant to be a commercial, I own 2 Legacy's and I know how hard it is to find someone knowledgeable about them.

Talking And yes, it is turbo'd :)

So I guess I am the only turbo'd BD9 Legacy huh...surprising...

Anyway the car is running trouble free...mostly. You can't really expect perfection when you add a turbo kit. Simple things tho; stalling after high RPM and depressing clutch (idle air motor) and playing the tuning game.

The car is currently pushing 9psi and loving it. Of course some parts need to be changed for durability/power. As far as I can see the engine is holding true to the added pressure. It's all in the tuning or precautional measures. That and you have to take into mind that you're not at full boost constantly.

There have been some more changes to the GT (wolf in sheeps clothing ) pics will come later. But if anyone has any Q's feel free to ask...allow time for reply.

Cool

Well, <i>Syms</i>, you opened yourself up to it...

<b>You are running the original Phase I block in your car w/o problems?</b> The general conception that I've picked up on here is that the bottom end of the phase I is undesirable (bearing position on the crankshaft) and so don't even think about adding horsepressure. Could you be shining a light at the end of my turbo-dream tunnel?

<b>Pics, man! We need pics!!</b> Truly. The Radio Flyer has been begging me for a super/turbo-charger for years now. I've only managed to put it off for financial reasons and the voices of doubt. I could mount pics of your sheep-wagon's engine under the Radio Flyer's hood to keep her enthusiastic and looking to the future...

Really though, any pics, dyno charts, timeslips, video, etc. you can share I (we) will most gladly drool over.

Default ASR...hmmmm!

Can you list out the parts needed for your turbo setup...and what added hardware you will be using to make your system even strong...i.e. to obtain more boost!!! I have a MY99 with a phase II engine...hopefully I can obtain the same 9 psi like you in the near future with no problem.

Would like to know what you use:

Turbo
Intercooler
Wastegate
Blow-off valve
Throttlebody
Head Gasket
Cams
Cam Gears
Pipe Size
Exhaust
Headers
Hi Flow Cat.
Ignition Sys.
Wires
Plugs
Intake
Fluids


It's a small list!!!

OK here's the deal. The kits will specifically be designed for the Legacy.

For the street version for all the EJ25's, the better match-up is the VF-23 or a VF-22 Hybrid. (This is for the street) (Both are IHI ball-bearing units)

For the street version for the EJ22's, the better match-up is the T28/T3

Both race versions will run a T3/T04E turbos.


The street versions will not be going for highest HP, but most reliability as well as best usable power.


Cost is still in the works right now.

Thumbs up Check out SSC October 2001

Boosted....the EJ25 is good on stock internals for 9 psi boost (peak) on 92 Octane fuel.

Here is the good part, it spit out 260 WHEEL hp @ 5900 (modified two wheel dyno for testing, buy the mag and read!)

Point is, I have been thinking (thinking hard) about putting in a turbo. I'd love to have the B4, but I don't think that's going to happen anytime soon And while I have heard great things about Rallispec, $6-$7K US just seems too rich, not that its not 'worth' it for them to do it.

GTBGUY,
When do you think you might been releasing more info on the Turbo kits you mentioned??? And, will it be compatable with the equal length header and catback Brullen system?

Talking Info for you guys

CRAZY KEN - iON Performance Inc is a new R&D co. that I'll be heading up. It's official "opening" is on September 28th, 2001

Keep an eye out for www.iONPerformance.com

DTR00GT - Yes it will be compatable with the Brullen cat-backs, that exactly the reason why we offer them in 2.5" or 3" ID's. However, the header may not work, I will have to look into this, as it would extend the up-pipe to too long of a distance and would thus loose thermal kinetic energy to spin the turbo.

Price isn't confirmed yet as I need to check out where I can get turbos for the best price/convience. If I source from the US, then there's double shipping etc.

1) Turbo = VF-22/or 23 Hybrids for street apps, T3/T04E for race app.

2) I/C = largest TMIC that'll fit under the Legacy hood. [B(D/G)5/9]
or for B(E/H) an Air->Water I/C

3) Cold Air Intake w/ shield filter etc.

4) Wastegate = Internal wastegate on the the turbo itself

5) BOV = Either Greddy, HKS, Apex-i or Turbo XS

6) Downpipe = 2.5"(street) or 3"(race), hi-flow cat (removeable)

7) Materials = Full T304 Stainless steel pipes (ie : up-pipe,
downpipe, I/C pipe, aluminum I/C)

8) Electronics = iON Performance Tuned EJ25 Unichip (takes care of fuel and ignition, tuned for 91 octane gas)

9) Boost Controller = Unichip boost module (non adjustable).

10) Fuel = (2) 480CC injectors with Unichip Injector Module and Hi-Vol Fuel pump.

11) Front mount oil-cooler.

12) Stainless will be used anywhere that it can be used.

13) We will be ceramic coating everthing that can be as well.

Street PSI = 7psi should give you around 200-230hp @ the flywheel at peak, but will provide a very usable power band.

Race PSI = whatever you want. (it may blow your engine)
Hard to say, but can get as crazy as the Imprezas!

This kit will be the first kit designed specifically for the Legacys, by a Legacy enthusiast Main goal is utility and reliability.

I would love to go TURBO. Because I have the 2.2 engin and I upgrated my clutch to the ACT street racing one. It would be so fun to do to my car, but I don't have the $$$ . Plus I don't have a extra car while I did the work on the car. This mod would realy turn my car into a sleeper

Any updates on the Turbo kit?

I would like to turbo a car this winter. I can do the miata pretty easily. $2600 gets me 50% HP increase, up to $4,000 for over twice the horsepower (not including drivetrain improvements).

I would love to do the Legacy, as it really needs the help. Besides, the AWD is begging for more power. For 6-7K the miata can out accelerate, brake, and out handle any production car I am likely to run across. Spending that much $$$ on a legacy just to get up to average would be a waste. I wouldn't heasiate to spend the $3K on the subaru rather than the Miata if the payoff was the same.

Default why I would turbo your current legacy

Instead of waiting for the B4:

1)
If you have the 2.2 or 2.5, you will get more low-end torque. It's for this reason I've contemplated a 2.2-litre kit for my B4. The factory motor is a great piece, but it's time for them to start using a larger motor for the B4 - and I've got a twin turbo with more low end than the single turbo WRX's.

2)
Suspension - believe it or not, but once you are starting to push into 280-300hp territory, you'll want to revamp the suspension on a B4. At the minimum, new anti-roll bars, ARB end links. Springs and dampers would be even nicer. The standard Bilstein setup is good - but not Great. Eifel and others do it better.

And those two factors above are also the biggest difference between a Japanese B4 and the American Legacy. So if you are going to end up swapping those pieces out *anyways*, why not save yourself a lot of cash and do it to a car that you already have?

I'm not aiming this at people that want a turbo legacy with a warranty - just at the nutters that want some performance beyond the stock.

mmm.. eifel..

brakes would probably be a good upgrade as well. i'm surprised that the b4 comes with the standard 2-pots rather than the 4's.

another problem with the turbo'd 2.5's is that there is no real standard for some of the parts. all of the kits are custom-built, so in some cases it's easier to find replacement parts for the ej20t.

paul - just curious. do you know if anyone has done a single turbo conversion on the b4 in an attempt to get more peak hp?
