October 3, 200718 yr ....about putting an EZ30D (gen1 thats from 2001~2004) 3.0L H6 in the RX instead. Its the same cubical dimensions as the EJ25D, 212hp/210tq and its N/A...so no complicated piping needed. Plus if i wire in the stock ECU from an 01~04, no need for tuning or anything. Oh, and it would be completely reliable.....and a complete PITA to work on in car.
October 3, 200718 yr i'm sure you thought of this, but the EG33 would probably be an excellent option as well. much easier to find, very, very reliable, non interference (well technically it's not but functionally speaking it is) and i think more HP. cheaper, just as reliable, and more hp.....lots of performance options for it too.
October 3, 200718 yr Author problem is that the engine is much larger than the 3.0...I am considering that option as well.
October 3, 200718 yr problem is that the engine is much larger than the 3.0...I am considering that option as well. gotcha, the EG33 fits in the XT6 if that helps you at all.
October 4, 200718 yr gotcha, the EG33 fits in the XT6 if that helps you at all. yea, but the ER27 doesn't fit in the place of a 4-cyl either. the EZ motors DO. I too have been contemplating doing an H6 swap using an EZ series. although given the news on NASIOC that the Link G3 will soon be able to decode the CAS signal for the EZ30DR.....I may go that route.
October 4, 200718 yr yea, but the ER27 doesn't fit in the place of a 4-cyl either.good point, though it has been done. more to deal with for sure. then the obvious answer is to get an XT6!
October 4, 200718 yr and it would be completely reliable..hahahaha.. hmm.. lol I thought the wiring on those 3.0 H6's was almost impossible to cut down due to all the inbuilt anti theft crap into the ECU and looms, blah blah... I sound like I have no idea, thats cos I don't.. Would be a sweet ride though.
October 4, 200718 yr the immobilizer was only on the gen2 ez30's in the usa. I want a gen1. Me too... My XT-6 needs some new go and I've been looking... best I can find is about 2 grand for the motor though....
October 4, 200718 yr i just had an idea for another project lol. whats are the dimentions on off the EZ30? Height length and width?
October 4, 200718 yr Me too... My XT-6 needs some new go and I've been looking... best I can find is about 2 grand for the motor though.... if you've already got the engine bay space.....go EG33!
October 4, 200718 yr I've been thinking along the same lines for when I smoke my turbo-wagon motor. I could pick up an ez30 for 450 max, it was in a flood car though. The insides of the valvecovers look good, but who knows about the cyl's. Engine management is what I'd be concerned by. If i could get the ECU and harness for it it would be awsome, but... I'm not sure it's available.
October 5, 200718 yr My only problem with the H6 is it doesn't have the low end power you'd feel on the ej25, driving around town
October 5, 200718 yr My only problem with the H6 is it doesn't have the low end power you'd feel on the ej25, driving around town :confused: how can a 3.0l have less torque than a 2.5l :confused: I've never driven one myself, so I don't know. but that concept hurts my brain maybe because they were all mated to 4EATs in heavy cars. the SVX doesn't feel like a terribly quick car in stock form, but an EG33 powered 5MT GC impreza is almost scary fast (got to ride in one of those a couple weeks ago)!
October 5, 200718 yr Author yeah, thats the other thing. The Ej25 in the same outback feels like a slug.
October 12, 200718 yr aren't the EZ30 a variable valve timing motor....if you where to use a stand alone ECU it would have to be able to control the funky valve gear
October 12, 200718 yr aren't the EZ30 a variable valve timing motor....if you where to use a stand alone ECU it would have to be able to control the funky valve gear only the EZ30R has the AVCS, so if you stick with the older EZ30s you'll have no problem besides, I thought there was a standalone system that could work with that variable stuff, but I might be wrong...
October 13, 200718 yr if you've already got the engine bay space.....go EG33! Or try a 4.44 gear swap in an auto (If that is what you have). That's for another thread though. WJM and his ideas.
October 13, 200718 yr Or try a 4.44 gear swap in an auto (If that is what you have). That's for another thread though. WJM and his ideas. or put the slushbox on the bottom of a lake where it belongs, and swap it for a real trans getting rid of the drivetrain loss of an auto would give alot more gains then regearing said auto.
October 13, 200718 yr getting rid of the drivetrain loss of an auto would give alot more gains then regearing said auto. wrong, but that's been addressed in another thread too. the actual numbers of the XT6 don't bear that out. the 0-60 times are nearly identical and the highway gas mileage is nearly identical too. that's what the numbers show and i've owned about 20 or more of these things, it's about what i've seen. the manuals "feel" faster, really mostly just in first gear, but that doesn't mean jack to a clock. at this point in age...the condition of the car and engine will be FAR more bearing on the actual "speed" of the vehicle than whether it's an auto or manual.
October 13, 200718 yr Author What he said ^^. The 4EAT transmission are awesome. Its the 3AT's that are not the best. However, I never got worse than 24mpg with my EA82T wagon around town...and about 30 interstate. 5MT was 22-ish in town, and the same on the interstate. For some reason my RX always got 24 in town and 36~37 interstate. (5MT D/R) My 4EAT outback gets 32 interstate. My 05 RS (5MT) only got 30~31. In town both get about 20~22. The WRX's (5MT) get about 12~16 intown...and 30~32 interstate. STi's usually do not exceed 26mpg on the interstate, thats a 6MT. Around town I never see better than about 8mpg with the STi.
