Turbo Legacy owners with aftermarket turbos please read

MY99 2.5GT · Post by **MY99 2.5GT** » Wed Feb 04, 2004 3:23 pm

I haven't seen any type of FAQ or information forum specifically made for turbo legacy owners with upgraded/aftermarket turbos.

So if you have a turbo Legacy or an EJ22G in your car with an upgraded/aftermarket turbo please post the following here:

1. What model aftermarket turbo do you have
2. What aftermarket intake and exhaust piping do you have
3. Intercooler Yes / No
4. How well does your aftermarket turbo fit that piping or how well does it fit your stock piping if thats what you have
5. What boost level are you consistently running
6. What model boost controller are you using
7. What EGT, A/F readings are you getting at those boost levels
8. What other mods did you have to make in order to compensate for the extra flow and boost

Your contribution of information and experience is greatly appreciated. It will definitely help myself and others as they plan to purchase a combination of parts to mod their turbo legacy or EJ22G.

Thanks
Brad

FWIW, I don't think there is an EJ22G.

EJ22G = Turbo legacy motor designation
EJ22T = Slang for Turbo Legacy Motor and used by those that don't know EJ22G

I think he's talkin about this:

www.sqc-ny.com/tech/turbos.pdf

The page notes that the mitsu turbos have different exhaust widths, or something along those lines.

Brad, if you ever want to take a look at my setup, let me know.

The biggest issue I have right now is the sizing of my injectors. Right now I'm running them at 100% IDC. Not good. But I've been trying to find a true drop in replacement. No such luck. Kelly, mentions the use of nissan injectors, but I have my doubts as to whether they're true DROP in replacements for the stockers.

It says EJ22T right on the id plate under the hood.

Thats cool.

Totally not what this thread was meant for. But please see this link for background information regarding the Turbo Legacy's engine designation: http://bbs.legacycentral.org/viewtopic.php?t=15132

Anyway I was looking for specific combinations that people are using on their turbo legacy or other EJ22G equiped cars. I thought it would be nice to put as much information as possible in a single thread for easy access and good reading. Please follow that purpose in your post.

Thanks Jason and Matt for your info. Jason I am still researching the fuel rail swap for a more available selection of injectors for fitment in the stock manifold.

Don't get your panties in a bunch, I was just telling you that EJ22T isn't something we created over here, it's written right on the id plate.
Have a nice day.

So a second generation Legacy sedan owner with a 2.5 litere engine is telling us what to call our engine?

MY99 2.5GT, you might want to try taking a look for another post in here (maybe someone else can help me figure out which post exactly) where vrg3 modified a stock n/a legacy fuel injector to possibly flow more . . . similarly to a modification done on the nasioc. A couple people were thinking of having those injectors flow benched at RC engineering, altho I don't know of what came of that.

Supposedly, the modification will close to double the flow of the injector, and if the stock inejctor's rated at 270-280cc, that would be somewhere in the neightborhood of a 450cc injector (I'm speculating). The saving grace in this mod is that the n/a 2.2L fuel rails swap into the ej22g with minimal effort.

In MY99 2.5GT's defence, I call the turbo legacy block an ej22g as well, just because it has some very similar characteristics to the ej20g, and IIRC, they were produced at arond the same time.

Who knows?

MY99 2.5GT · Post by **MY99 2.5GT** » Wed Feb 04, 2004 8:38 pm

That would be so sweet since I have a perfectly in tact 2.2 NA fuel rail. Let me know when you find out about this mod.

ciper - I guess my 95 Impreza with an EJ22T motor ready to go in isn't in my profile. I'll refer to it as an EJ22G/T so as not to confuse anyone here:)

91White-T - Their Depends, get it right

MY99 2.5GT · Post by **MY99 2.5GT** » Wed Feb 04, 2004 8:39 pm

ciper - Do you have mods done to your turbo legacy?

91White-T - Care to talk about the experiences you have hadwith your mods?

ciper · Post by **ciper** » Wed Feb 04, 2004 8:44 pm

I know what will fix this. The BLOCK alone is referred to as an EJ22G. A complete engine with all the items attached is an EJ22T. See the difference? We are all running EJ22T while the WRX guys (for example) are using EJ22G blocks.

Do you mean current mods or planned? My engine is still on an engine stand, the heads are at a machine shop and the other parts are in the trunk of the donor car.

The modifications on the recieving car are extensive though. I dont drive it as often, I usually drive my sedan to work. Probably the most interesting modification that is taking place at the moment is a high quality head job on the stock EJ22T heads and conversion to roller rockers.
Here is an old thread but with lots of my info. I should update it.

Well there ya go. I didn't mean to cause any trouble, but I hadn't even heard the term EJ22G before. I understand that it may be the block designation as Ciper mentioned. You learn something new every day!

I have the set of modded 92 NA injectors and I did offer to send them to RC for testing if anyone wanted to pay for it. I emailed RC asking how much it would cost and what I would need (since the o-rings don't look so great), but haven't heard back. If anyone does want to pay for the testing I'll call up RC to find out.

Or when the weather's warmer, I'll just make my own ghetto DIY flow bench to test them with. And hope I don't blow myself up. :)

On-topic portion of the content: Matt's right that the exhaust side shouldn't be a problem, and that the compressor outlet differs, but you should also be aware that turbos meant for 1997 and later model years also have a different compressor inlet. The stock Legacy Turbo compressor has an elbow bolted to it pointing straight up; later ones don't have that bend and instead have the intake tubing go under the passenger side intake manifold runners.

Get the price. Ill pay upto a limit.

'kay, I'll find out how much it is.

PS Don't take me too seriously, I was jokin around earlier...

MY99 2.5GT · Post by **MY99 2.5GT** » Thu Feb 05, 2004 2:48 pm

Honestly I really appreciate you guys and the information I find here. Its good to joke around every now and then.

I will be starting over piping wise with my setup since my engine simply came with the intake and exhaust manifolds and no up pipe, or intake piping. I don't really like the WRX idea of having the intake run underneath the manifold so I may try and jimmy my own little fitting to route it up and around. I need to take some measurements once I get it in the impreza to see what will fit.

Thanks
Brad

1992 White Legacy Sport Sedan 5mt turbo

Removed snorkus, K&N filter

Saab 900 TMIC. I plan to cut in my WRX hood scoop this spring to help it breath better.

Diamond coil pack.

Joe-P MBC set at 12.8 psi on stock VF11 for now with plans to run 14-15 psi once I have a FCD. I hope to run a TD05-16G or VF23 in the future.

OBX Type R Turbo gauge 30-0-30 vac/boost. (Total piece of crap! I need an Autometer

)

C.E.S. Racing Systems "street" 3" turbo-back exhaust with DP03 ceramic coated twin dump down pipe and BEP (Boost Enhancement Plate).

I'm not running an EGT or A/F gauge yet so I can't help there.

if your not driving the car, and i'm assuming you'll be doing piston and conrod upgrades, why are you wasting your time with SOHC heads? you could get DOHC heads easily if you shopped around and they flow good enough standard, just get some eagle rods and CP pistons with DOHC heads with your 2.2ltr block whack on a nice big TD05 20G and you'll have a monster, obviously you'll need engine management, injectors, rising rate fuel regulator and a high power fuel pump, also parallel fuel rail conversion wouldn't go astray either

subiecar · Post by **subiecar** » Mon Feb 09, 2004 4:22 pm

Everyone seems to think the stock EJ22T heads are`nt good enough for the street---WRONG!!! As has been said before, put your money where it`ll do the most good, ie: intercooler, engine management, better pistons, rods, etc. My heads after being LIGHTLY ported, CC`d, stock size s.s. valves, titanium retainers and SLIGHTLY revised cam profile are good for at least 400 HP and comprable torque (with the proper related components, of course.) Ask larry Witherspoon (ssspoon) how effective HIS $ were on his head project (he`s now selling them.) Unless you`re looking for well over 400 HP and higher than 6500-7000 RPM, the SOHC heads are just fine. Once my never-ending project is broken in and the GT28RS turbo is installed, I`ll verify my statements with a run at Infineon raceway some time this summer. I`ll be happy to post the results. Continuing to believe less is more..........Rod

"GT28RS turbo" Is this the Disco Potato your talking about?

Brad[/code]

ciper · Post by **ciper** » Mon Feb 09, 2004 8:34 pm

No piston or conrod upgrades. Seeing the amount of abuse the OE parts can take I have no reason to spend the money on less stable aftermarket parts. I have yet to see any damage to stock EJ22T internals (from high power)

Dont even mention DOHC conversions. The money it takes to do such a conversion is far better spent on improving the flow of the original. Ive done more research than has been posted (lazy to type) and the DOHC heads dont automatically increase power. The difference I see is seperate timing control over the valves (which I have seen NOONE do). The DOHC have more rotating mass and friction, you end up loosing power. Besides I would need to create custom ignition wires to fit the center mounted spark plugs. It doesnt help that the DOHC heads available dont have the correct bore.

I havnt decided yet if I want to perform the parralel fuel mod.
