Another Swap Question, (already searched)
Posted 09 July 2008 - 09:22 AM
What is the Horsepower difference between the phase 1 and phase 2?
how long does this swap usualy take with all parts (mostly) on hand
How many buddys do i need to help lift and restuff the engines?
Is it a good idea to install updated head gaskets and studs on the Phase 2 before install?
Final Question, would i be better off just doing the 2.2 swap? will i miss the horsepower if i do?

plug and play. this variety plugs right in no problem.
intake manifold swap. if the original intake bolts up to the new block then it's easy becuase you're retaining the harness and electronics of the old engine anyway.
the last resort is to swap your existing wiring harness (the Phase I that's in the car now) onto the new Phase II intake manifold/engine. swap everything, all the sensors too. not that hard and it's the sure way to get it to work.
the only thing i'm not sure of is if the cam sprockets will work. that's alleviated by just swapping the cam sprockets usually. but in this case when going from DOHC to SOHC...i'm not sure the sprockets are interchangeable in the same way they are on other EJ's.
you're not reallying getting a HP upgrade with the Phase II EJ25 if that's what you're after. but they are a better motor in my opinion.

Only if you drive on the edge all the time. EJ22's are super reliable!
I'm mainly after the whole dependability factor, i would do a EJ22, but i dont know if i could handle the horse power loss

i've towed small trailers with riding mowers with mine (EJ22) with no problem. light stuff like that, it's like it's not even there. there's a number of towing threads, maybe you could check those out and see what people with EJ22's are saying.
i can't imagine you'd have a problem. maybe if you're driving over mountains you'll need to downshift to 3rd sooner, but even the EJ25 will need to downshift on steep mountain grades.
i haven't gotten many answers to upgrading an EJ22. i would imagine an exhaust or intake change might make a small difference but it's not going to bump you 20 hp that's for sure.

I've read on here (I think) that the torque of the 2.2 and the 2.5 are comparable. So towing shouldn't be an issue.
If you drive up into the mountains a lot, then the 2.5 may be better.
Check out cars101.com....I believe the 2.5 was 155hp in '96; 165hp '97-'05?; and 170hp currently.

Well i guess my only concern is that i tow a small 14 foot fishing boat with my car, and i dont want to come up short on the hills and boat ramp. can i juice up the EJ22 just enough to have the same performance if not more then a EJ25 dohc, without making it a whole lot less reliable?
another option is to do a hybrid motor with the EJ25 shortblock and the Ej22 heads. It will give you more torque b/c the set up is a high compression motor. You can get a set of junkyard Ej22 heads and rebuild them while the Ej25 is still good. Then when the HG give out, pull the motor, and plop the new heads onto them and put the motor back in. I am sure there are a few other things you have to do but this is a weekend swap that will definately work.
Another thought is to just do the HGs on the EJ25 when they go. The newer HG are of a good design and I have heard good results after they are done. You can even go with cometic head gaskets if you really are paranoid.
just my 2 cents.
