Wrx Gear On A Ej22?

BrennyV · Post by **BrennyV** » Thu Apr 10, 2008 4:16 pm

Now I don’t want a thread full of whoring and crap id like to hear factual or helpful ideas

I’m curious to know who has played with the oz delivered sohc ej22 blocks and what they have done with them. Reason been is that I have a whole heap of bits laying around and I wouldn’t mind having a go at building a new engine.
One idea was to use some wrx EJ205 heads (non avcs) on a ej22 block running a wrx inlet manifold. Keep in mind I don’t want big power but more a torque/responsive engine with some boost (not mega) for a good little offroader.
I only have a very vague idea atm but I wish to build on this and get a good understanding for building engines and make my first project a good one.
So all input would be greatly appreciated
Cheers Brendan

theres a heap of stuff on rslib about using 2.2 blocks just gotta hunt around for it http://www.rslibertyclub.org/

the go seems to be,
ej22 bore (either ej22 block or 2 litre block bored and sleved)
2.5 crank
Forged rods
Offset Forged Pistons (to suit the 2.5 crank)
whatever heads tickle your fancy at the time

as for what sort of power a standard ej22 block can handle, thats a good questions and theres lots of opinions on that, so ill let you go hunting for that one, as i havent actually done it yet

my next motor will be something like this tho

I was going down the path of a stroked 2.2 with a semi closed deck block. This seems to be a reliable way of obtaining heaps of power without going the 2.5 option. Have a look on rexnet and as mentioned RS Liberty club website as there are a heap of people doing this and or providing a short motor with all the goodies...

i basicly have all the parts to build it.
main thing is most builds on rslib etc i have found are for big hp / race builds.
nuthing like what i want to do. but still good things to know i spose pros and cons with some of there setups

A mate of mine was running a stock EJ22, although it was reconditioned, with turbo heads and 10psi boost. No problems at all. It was more responsive than his EJ20 and had more torque down low.

ahhh cheers Brett this is what I want to hear. I really love the torque and response of the ej22 short motor just a little unsure of the stability with boost, but I would love to see what they are capable of

Id like to utilise the sti yellow tops for squirters on the MY99 manifold and run a TD04 for boost. I like the TD04 for a responsive all round turbo, I know they don’t hold hard/high boost top end but that’s not what I’m after

rong ej22's tho cam. they had the turbo models over there. and most builds they have on 22blocks are for like 800+hp

Ok, my plan of attack so far.
I have seen various builds and spoken to a few people now running ej22E blocks with turbo setups. Some much wilder and in my eyes riskier than others.
So what I opt to do is something that seems to make sense and also looks to have been used by a few gurus in similar applications.
I will go NA crank and rods using the USDM EJ22 turbo pistons (tho if I can source a complete EJ22G bottom end id be chuffed), They have been tried and tested for long periods of time with lo (10-14psi) to high (18psi) levels of boost. it would appear also running these pistons will give me a good CR of around 8.5:1 give or take.
I will utilise the quad cam WRX heads from a 2000 ej205 engine, using the matching 2000 WRX manifold and yellow top injectors.
Boost will be delivered from a td04 turbo at witch I’m looking into getting ported/high flowed for great low end spool response. I will run the stock up pipe and headers to start and will look at maybe upgrading to equal length if I see its needed.
As far as cooling I’m looking at going water to air for the turbo as its primary application will be for offroading. I will also look at running a large oil cooler to ensure the oil temp stays cool.
I have not gone as far as what harness or path to take with wiring, I’m leaning towards running a GC8 WRX harness to match the manifold and a aftermarket ecu. It’s more of a case of gathering parts.
So this is my update so far.
Ill keep you posted on my path and pictures with updates, please still feel free to help with information and ideas
Thanks
Brendan

Consider running it on early RS spec for the harness, there are so many parts and detailed knowledge available. The RS manifold is supposed to be better too.
Also I have a complete 1996 WRX wiring harness which you could use. You'd just need to source the little engine harness to run under the manifold and an ECU.

(of course you could run a standard EJ20G closed deck block with the wrx heads & turbo, would be pretty quick,easy and cheap and we know it's tried and tested!) <-- had to add my 2 cents

Remember you will need to source an L series turbo engine crossmember to clear the exhaust or hack a section out of your one and weld in a concave section.

Hey are you still running the radiator without the coolant filler neck? If so this is good because you can just add a standard turbo radiator header tank and there's your turbo cooling sorted.

This engine won’t be for Leone, it’s more of a side project to build a good low end torque monster off-road engine. I feel the EJ20G’s / 205’s lack low end torque, that’s why I want to go down the path of the EJ22E block or EJ22G if I could obviously about 10% gain of displacement and extra torque.
