hey everyone i was hoping to get some information on what availability there is for a single turbo kit that bolts on to an RX EJ25. i put this engine in my gen2 GX after the timing belt broke on the GX 2.2L engine, and i was just curious as to what i can do and how much it would cost for a turbo kit for the 99/00 RX EJ25 engine we put in.

what will i have to do for strengthening?

any main issues i need to know/steer clear of?

and any personal experiences with turbo'ing this model engine would be great.

i don;t know a whole lot about the mechanics of this engine, but i do know the basics

(i'm only new on here so i hope this is the right section to post this)

cheers any help is much appreciated,

Hey mate,

Don't mean to be a wet blanket but going to go right ahead and say it.. Dont bother turbo'ing the 2.5 - they are terrible engines mine blew up at 80,000kms - also well known for headgasket failures.


My suggestion would be

1) Buy a front cut from a WRX or GTB(if you have too). This will come with all parts needed.

2) Send the looms up to AMauto to have them spliced, and joined. (if you buy the GTB front-cut you wont have to splice the looms).

3) Get a mechanic, or a few friends to do the conversion for you... (I work in IT and managed to do it, Its hard but was a valuable experience).

4) Drive away in something much more reliable than a bolted on EJ25 turbo setup.


I don't believe there are any turbo kits for the EJ25, as you would need to change the heads? compression ratio's, ECU and a few other things I think.

as said above best bet is to get a frontcut, it has all the turbo goodies, including a gearbox that will last and an engine that would actually hold boost

just buying a suitable intercooler setup and turbo and exhaust would cost you well over a frontcut price

you also would need a lot of work done to the internals eg, pistons, new turbo heads, etc etc all adds up

but at the end of the day its up to you how you want too go about it

also getting a frontcut means you have every piece to the puzzle, no running around looking for little bits and pieces

Hey mate,

I was considering this with my wagon. Upon further research I promptly ditched the idea, and went with a STi Ver3 half cut.

As said above, the amount of work you would have to do to make it reliable, would far outweigh the costs and benefits of getting a half cut.

PM fatdon on here, I think he has a GTB engine which would be a better go. Or smash up eBay.

With regards to wiring, as others have suggested, send em up to AL at AMAuto, I sent mine up there.
I tried to do the wiring myself, and gave up after looking at the loom on the ground.

So, at the end of the day, ditch the 25, crank out some sort of factory turbo engine. Most EJ20Ts should bolt straight in?

Oh, and welcome to SC mate.

Cheers,
Shazza

Just further on the advice already given, the GEN 2 GX is a good car. But a good base for a turbo conversion, maybe not.

I'll get flack for mentioning this, but here goes, there's always the option to sell your current car (if it's in decent condition go for it) and purchase say...a GT-B or even an RX to convert. GX + Decent Conversion price stacks up against a GT-B price as around the same.

Save yourself a bundle and just buy a turbo Subaru.

[krusty]

thanks heaps everyone, i did think that a halfcut would be better. Guess i should have looked at that when the 2.2L shat itself and we put in the EJ25, oh well ill have to wait and see, think ill just save my money and go for a GTB or a WRX somewhere down the track


thanks alot for the info!

[Shaz]

Save yourself $6k mate, and you'll get it all done, with quality bits, so long as you can do the mechanicals yourself.

Is this all the same case with the gen3 EJ25 RX's?

[aekOne]

sure is mate

Can I just be upfront and honest?

Enjoy your car as it is, when the tine comes, get a factory built turbo subaru

Disagree.

Built > Bought.

With regards to above.

Expensive > Convinience.

[Soop]

what?
Unless you rebuild the motor its never going to be better. Conversions always end up with dodgy little things.

[alexGT]

i've done both. unless you can do 95% of the work yourself and put the time and effort into doing it properly, save yourself the heartaches and wasted $$$ and buy one already done/factory turbo subaru model.

[Shaz]

But it's way more fun and rewarding, and, if done properly, can end up better.

Of course, if you don't know what your doing, or you don't want something semi unique, then buying an already turbod model is the way to go.

just keep it stock , and save up for a turbo car !!! a lot less dramas

[krusty]

im not saying i dont enjoy my car as is,
i was just curious as to what can be done,

i am going to save and buy a turbo subaru down the track though, it seems like the best place to start, because i can add and change things. starting with an already finished canvas, and changing/swapping seems to be alot easier.

Good decision.
