Default EJ22 best power mods???

so i have an EJ22 with a bad rear main so im going to rebuild it. ive read some of the stuff about how "universal" all the EJ series parts are. i was just wondering what you guys think are the best ways to make more hp out of the stock 2.2 block.

thanks in advance,
Ben

EDIT - jesus, I see this is a 5+yr old thread that ws bumped today. oh well, ScootSpecs and others may find it useful I guess.



EJ22 or EJ22T?

If EJ22, then look into the frankenmotors built with EJ25 bottom ends and the EJ22 heads (and all sensors, etc..).
I want to build a new motor for my Vanagon (that I swapped a EJ22E motor into) with a EJ257 block. The Sti SB mated with the EJ22 heads yields ~10.3:1 compression and puts out a good amount of torque (more displacement, higher compression, small ports).


If it's a 22T - then see Fuji above^^

EJ22NA, I'd just toss in an EJ25 engine. Cheapest bang for the buck upgrade. If you want to make more than just 'perky' power...well I'd start with a turbo motor swap.

No reason to dive into an engine build if you can get the same or more power out of the junkyard

I was talking about the EJ22 N/A, currently powering my 97 GM4

And I'm interested in best bang for the buck, seems like EJ25 swap is the way to go. My previous vehicle was a 98 Forester, and I loved the grunt of the 2.5, I bet it would be even better pushing 300 less lb or so.

In the meantime I'm thinking Stromung high flow cat, and Perrin lightened pulley, would these mods give me any noticeable results?

The cat probably won't do much, the pulley will give you a bit quicker rev up so rev matching should be easier.

in that case I think I'll just put the money towards a future ej25 transplant

she is also an auto, so rev matching is very easy

Engine build (2.5 block with 2.2 heads) in this case means no additonal wiring/sensor work.

The EJ25 swap would involve more than just tossing in the motor, right?

Not being an ass here, and granted I have not built a 25/22 frankenstein, but it seems like 6 of one and holf a dozen of the other... maybe the later 2.2's are setup better for a 2.5swap(?)
The 2.5l (no mater how you get there - either way is cheap) will be noticeable in your relatively light car.

pulley and a cat will not be noticeable.

And auto? For more "pep" you may consider a 5spd swap (or a car with a 5spd in it already)

Thanks for the advice, I'm really digging this 2.5 block with 2.2 heads idea. I'll look into that some more. What else would I need to do the swap, besides the 2.5 block?

In the meantime I just had a 3A Racing straight thru muffler installed yesterday and lovin it, noticeably louder without being obnoxious, plus shaved off 12lbs to boot

A '97 eh. that has them 40cc heads I believe.... drop in a '99-01 SOHC EJ25 NA shortblock and use your heads. It'll bump up compression quite a bit and you should have some grunt!!! You will likely have to run 93oct to keep det down.

You'll need the 2.5 head gaskets. I believe everything else is the same. Plan on running premium at all times and keeping up on intake system maintenance.

I think your motor has the idle control valve on the intake manifold, instead of on the throttle body. This means you can literally swap in an EJ25D with only swapping your engine harness over to the EJ25D intake manifold, and swapping exhaust manifolds as well.

That would be the quickest and the easiest, not to mention cheap. If you can find one at a junkyard, you can rebuild it in your garage on your own time.

Raised compression and running premium would be no prob, and the idea of extra grunt just has me wanting this more and more..

Thanks for bringing this thread back to life folks

Few more questions: will my stock 4spd auto handle the extra power? I like auto (daily) and don't plan on swapping to 5spd. I do plan on installing a transmission cooler.

so as far as electronics go, I can use all my stock fuel sys/ecu/injectors? if so this swap sounds like total win

So I have been looking but cannot seem to find this "frankenmotors build", could you maybe show me the thread?
