Default 96 legacy 2.5 head same as 2.5RS?

Is the 96 legacy 2.5 head the same as my 2000 2.5 RS head? I need to replace my head, thanks! If not, what are the differences?

I thought the 96 Legacy was a DOHC? The 2000 RS is a SOHC.

WAY different. although, i just saw a pair of DOHC heads on ebay last week. why do you want to know? i cant remember if you can run SOHC heads on DOHC engine management.

The '96 DOHC Ej25 heads are unique to that engine. Those heads have HLA's under their buckets. The '97-99 DOHC EJ25 heads have a shim over bucket design. If you are only replacing one head, it will need to be a '96 head. You could replace them with a pair of later DOHC heads, but the SOHC heads are not an option...

i'm not usually one to correct (especially not mr. monson), but i think you've got it backwards. he's looking for heads for his 2000 RS, in which case he would have to stick with similar vintage SOHC heads.

When I am wrong I should be corrected...
Any SOHC Ej25 head will work for his car...

Except an '06 head with AVCS of course. Twice in one day, doh!

@OP: What's wrong with your head that it needs replacing?

thanks for the info. i thought the '96 was a SOHC, if i knew it was DOHC i wouldnt even ask.

oh and was wrong.... im pretty sure i dropped a valve the over day. i was driving down PCH at about 50mph in 5th gear and i hear a big bang, pull over and the spark plug for cyclinder 3 in sitting near my battery. The threads are completely gone on the head. So best case i need a new head. worst case i broke a valve ****ed the cyclinder walls and need a new engine.... kinda sucks.

im looking at the EJ20"DET" but i cant find a place that knows what they are talking about or has an ecu to go with the engine,

maybe the spark plug just got loose and poped out. I've done this before. Are all the threads gonzo? Helicoil?

Sounds like the plug was just loose for so long it destroyed the threads. Helicoil repair should fix that.
