I finally tore down my old EJ25D that blew up a year ago.
The #2 rod pretzel'd itself. This was at about 16 PSI on E85, or about 330 CHP.

Hahaha, holy hell!
I've been to boost and back again my friends... and it was good
yours must have been a 1999 block correct?Originally Posted by anothernord
the older, 48mm journal usually wont hang on to 330chp.
what pistons were u using in that??
No, no ,no I'm not insulting you, I'm describing you!
It was a Phase II block (or so I thought), but the thrust was in the #5 position, so I'm not totally sure. The car had a shortblock put in before I owned. Pistons were the stock square dish kind as well, that's all I know. They weren't any obvious signs of detonation occurring, so I think the rod just gave up.

WOW I did that when I owned my Ford Thunderbird Turbo Coupe.. It didn't like 21 psi
thats impresive!
No, no ,no I'm not insulting you, I'm describing you!
So I realize I have posted in here probably a little too much BUT I just picked up another wagon the other day. It has a 2.5 with the start of a rod knock. I still have my turbo and header. Since I have to rebuild my motor anyway, is there a bearing company you guys would recommend IF I wanted to toss on the turbo and run say 8psi MAX with an RRFPR or whatever psi the stock injectors will hold up to? (I think it's 8psi for the EJ25D injectors). I would also pick up a stage 1 clutch kit to handle the boost. I like the feel of the heavy flywheel the car comes with so I'd just leave that in there (but go new of course)
questions are good.
ACL are the best, but remember fixing a rod knock is a little more than just 'slap new bearings in'
its so difficult to say yes you can do this and no you cant do that.
trial and error is the best way to know what is possible.
and just run your plan past someone with more experience before hand.
i never do anything risky to my car with out running it past my boss, chris.
it just helps to have someone un-bias give feed back.

From what I have been told the 253 short block will stand up to boost better than the 25D. Of course I will be using my 25D heads so I don't have to mess with wiring (screw merging harnesses, that's a pain). The guy I got the 253 block from also tossed in a 10mm oil pump for free.

The pistons are porcelain, definitely Shit for boost. They are compatible with STI parts though, so if you intend to go that route swap in STI rods and pistons. NOW you're talking!!
I've been to boost and back again my friends... and it was good
I wonder how much I could find the sti crank, rods and pistons for although thats a big drop in compression ratio. What yeah sti or what motor should I get STI parts from? One last thing, how do I know for sure if it's an EJ253? I can tell it's a newer style 2.5 block.Originally Posted by Garrison
the sti and 253 cranks are the same.
the stock rods are good for 300hp
and the pistons are fine, but they are not compatable with vary many heads.
the pan is a easy way to tell. if you dont have the pan, the pistons on the 253 have a weird partial dome thing.
the 251 is almost completely flat aside from a 6cc dish.
No, no ,no I'm not insulting you, I'm describing you!
Yeah it's a 253 then, the pistons have what I'll call humps coming off of them. I'm actually going to hold off on turbo-ing and rebuild the 25D, clean the car up and sell it for near blue book price. Then buy a Subaru that's already turbo figure that's easier than trying to build my own setup.Originally Posted by lord flashheart

The oil feed line is easy; you just undo the bolt that is bolted into the gallery, and put the banjo bolt and feed hard line in.Originally Posted by LGTtoBE
The return line is NOT drilled into the heads. You have to take the engine out (and apart, really) to drill out the blank casting for the return. That's why I suggest returning to the valve cover.

I thought I'd stop by to ask a few questions about my turbo swap I have planned for my budget bomber.
Stock set up is 5mt with fresh clutch, and stock EJ22E
I currently have the following parts in my possession:
TD04 from an 04 FXT
TD04 from an 02-03 WRX (LOTS of shaft play, will be rebuilt for use as spare or to free up more funds)
TMIC from an 04 FXT with y pipe and BPV
TMIC from an 02-03 WRX w/o BPV
Turbo exhaust manifold from 02-03 WRX
Megan up-pipe from 02-03 WRX
Stock injectors and fuel rails/piping from 02-03 WRX
Under manifold portion of turbo inlet from 02-03 WRX
As far as I know, I still need the following:
Downpipe (have a line on a stock STI one)
Turbo Crossmember (Also have a line on an STI one, understand will need to use WRX control arm bushings due to their width.)
Turbo water pump to clear exhaust manifold
97-99 25D heads and manifold to match block bore size and drop CR to boost friendly levels
OEM EJ22E headgaskets
Miscellaneous hoses, tubing, etc for water and oil feed to turbo, PCV/IACV routing
So my questions are, am I forgetting anything? And are the EJ25D heads REALLY my best bet? I'll admit that I'm a little intimidated by the DOHC cam aspect, as well as frustrated by the spark plugs coming straight in from the sides.
I have access to a set of SOHC 2.5 heads, pretty sure they are 251's, but am not certain. Would these heads be a reasonable, simpler option? Either way I'm going to be going all the way through whatever set of heads I end up with. If the believed 251 heads are usable, which manifold, sensors and ECU would I need? I'm under the impression that using the EJ25D heads would allow me to just continue using the 2.2 ECU.
Sorry to blow up/hijack you guys' thread, but I'm getting close and am trying to iron out all the details!

Don't use ej22e head gaskets, the coolant ports don't line up right with the head and you'll end up with cooling issues. The Victor Reinz ej222 gaskets are the most cost effective way to go, look them up for a 99-01 impreza.
If you're going to do a head swap the 25d will run off your existing ecu, the 251 heads will as well but cold engine idle will be garbage and you'll have a constant cel. Unless you can find an ej18 throttle body. It has the iacv built into the throttle body similar to how the 251 does, but the phase 1 ecu will run it correctly.
The only way you'll be able to use the wrx injectors is if you use the sohc heads, and a manifold from one without the air assist fuel injection. I can't swear by which models have it and which don't.
The 04 fxt intercooler won't work because of the bov location, it's right in the way of the throttle linkage. You could run an 02-05 wrx throttle body and cable because it's on the opposite side, but then that leads to shit cold start idle and cel again. The 02 intercooler will require at least "massaging" of the firewall and if I remember correctly moving the ignitor and bracket. The ignitor part may have just been on the gen 1 turbo legacy, it seems like the one on my 92 ss was bigger than my 97.
Honestly the 25D heads are better than the 251 heads anyways
No, no ,no I'm not insulting you, I'm describing you!
I've always thought they were as well. I remember the old arguments all over nasioc saying the 251 heads flowed better because the engine had more mid range torque than the 25d. nobody gave any credit to the higher compression or ecu tuning differences between the two.
I would say run the FXT intercooler and just crush the head of the BPV valve. It won't cause any difference in the operation and it'll let you keep your cruise.
the 02 is huge-mongous for the bay of an ej22, ej25 engine.
I've been to boost and back again my friends... and it was good
So, the complications of the DOHC is well worth it for ease of availability and over all better-ness? Copy that. Do I need the manifold for those heads or does my 2.2 manifold work?
Anybody have any information on exactly what part number I will need for the HG's?
I think I like the idea of using the FXT intercooler a little better, especially since I'm not at all skerd of doing a little hammer clearancing to the BPV! Is there such a thing as a low-profile BPV/BOV that would solve the problem?

You've gotta use the 25d manifold as well.
Victor Reinz # 54423 are the ones I've got in my high compression hybrid. which is the same as what you'll be doing but with eg33 pistons. They match the bore and the coolant ports on the 25d heads perfect.
I believe the Phase II SOHC heads interfere with the up-pipe anyway.
And you can't run the Phase II SOHC heads off the EJ25D ECU anyway, since the cam pickups are different.

Some early 251s ran phase 1 cam and crank triggers.
25D heads it is then. Found a set in usable shape for $80, just gotta snag a manifold from somewhere!
Also, anybody know anything about a low pro Bob/NOV? My google search skills bring the suck.
