Default Aftermarket JDM waterbox?

I've seen several aftermarket shiny billet options for replacement waterboxes for usdm wrx and sti. I've already replaced my oem crappy plastic endtank radiator with an all aluminum 2-core.

Are there any aftermarket choices for JDM wrx waterboxes? I find myself in a position where I need to replace my waterbox and would like something nicer and certainly sturdier and non plastic.

What idiot thought that plastic coolant system components are a good idea? They are definitely cheap enough to manufacturer but that certainly does not make them high quality or really much of a good idea.

All that is is a over flow resevoir not really important enough to need to be metal.
When your system gets too much pressure your cap opens and lets water into it to relieve pressure

Not important? I respectfully disagree. You may not think its important until it develops a crack because its plastic and stops holding pressure.

It actually serves to pull coolant through the turbo after you turn the car off and the coolant is contracting. I would say its pretty important, luckily my k came with a metal one. The actual coolant overflow tank serves a totally different purpose.

My 02 WRX ej20t came with a metal coolant reservoir on top, near the turbo. it developed a leak at the base of the spout where the coolant cap twist on, then ruptured. Yeah metal is better than plastic my ass!

So when I replaced it, the parts guy at subaru gave me a plastic replacement.

I like plastic as well, for weight savings at least. I wouldn't hesitate to use one if a new metal wasn't available. Mine is a 1997 model though and if you keep the coolant to water percentage high enough to prevent corrosion, there should be no issues. I actually use toyota SLLC pink coolant. You can always have the metal ones brazed or soldered if they are damaged.

Uh huh. The differience is that when a metal one develops a crack its because of cheap metal or poor oem design. When it happens with plastic its not because its cheap or poor design. Its because its plastic.

When you heat and cool metal it expands and contracts and within the temperature range of that material it can do so with no fatigue. With plastic that expansion eventually breaks down the material because the heat range is much lower and smaller.

Its hidden by the inlet but you can see the part that counts. Its oem, you could probably just check the for sale ads where people have blown their engines and are parting out. It would probably be easier to find on RS25.com. I painted the top cover with black wrinkle paint.

MRT makes one, it think ARC did, but they are gone.

I just delete it on all the swaps I do, never had any problems.

I dont have a swap. I've got a jdm car with a factory ej20g. Im looking for something that will fit.

I've seen the moroso waterbox. And then there is the forge motorsports waterbox.

These are not for a gc8 ej20. There would be a great deal of hose rerouting.

Forge makes them for every GC8 turbo version
V1/2-V3/4 and V5/6

This is one company that sells them.

Nice. Thats exactly what I'm looking for. Now to find someplace slightly more local to get one from. Hmm nm that it seems that most Forge motorsports dealers in north america dont actually list forge motorsports products in their stores. I suppose other then cost there is nothing stoping me from ordering from the UK.

Wow $238 Canadian for that one from the UK... that's a little ridiculous. People say we could use the 02+ tanks but requires some modification. Nobody has any details exactly though. Pretty sure mine is leaking again too.

I don't know what you want exactly, but I am pretty sure I can fab up something far cheaper then that.It would not be polished, but would come unpainted, or powdercoated (at a little extra time)

Only thing I would need is a detailed drawing with measurements for hose barbs etc.
I have a OEM V4 tank here, which I can take measurements off of, but not anything for the V1/2 and V5/6

Someone on WSC was going to make one out of aluminum or something. They just needed material to weld. I don't know... nobody has any solution for us =(
If someone's got a spare, they can send it to the netherlands so dutch scooby lover can make something haha. Seems so far!

I still have my old v4 stocker.
If I look at it correctly Forge make 1 version for V4 and earlier, a version for V5/6 , and a third version for everything after that.If someone can confirm that the V4 will also fit I can copy mine no problem (but until after someone confirms that the V4 version will also work on earlier models I can not guarantee fitment)

Forge motorsports appears to have a "master dealer" in canada. I dont know if this means I can order what I want from them. The dealer is JRP in ontario. I called them and they refered me to a local JRP distributer local in BC. It sounds like I can just order what I want.

I'll let you know how it turns out.

I apologize to those that have it, but I have yet to see an 02+ tank on an ej20g that isn't, IMO, sloppy.
