ej22t heads up-grade

NICO · Post by **NICO** » Fri Dec 23, 2005 10:49 pm

well i gave up on the wrx heads so i have a new plan, im sending in my factory heads and getting bigger valves and re-grounded cams for more power. im going to try and make the most out of the heads with the most power i can get.

anyone have any comments or done it to let me no what i should look out for.

Use the 22t gaskets. Your compression is gonna be higher. Use the WRX manifold, and your gonna have cam sensor issues if your still using the factory ECU. Any DOHC Tbelt covers will work, but I dont feel are so neccisarry.

NICO · Post by **NICO** » Sat Dec 24, 2005 3:50 pm

so if i use the 22t head gaskets my compression will go up not down?

what do you mean bye having cam sensor problems with my ecu?

bmxpunk · Post by **bmxpunk** » Sat Dec 24, 2005 7:33 pm

The wrx has different triggers on the back of the cam sprokets becasue the ignition system is different-not wated spark like the 22t. i think dzx has some insight on this as well.

let me know how it goes, I am thinking of doing this wit hthe new 22t block I just got.

NICO · Post by **NICO** » Sat Dec 24, 2005 9:06 pm

its a sensor that is stoping me? what if i use my 22t sensor in its place will that work, or no sensor at all or you can do that.

bmxpunk · Post by **bmxpunk** » Sat Dec 24, 2005 9:18 pm

Its not the sensor, more how the ecu works. I am prettty sure (correct me if I am wrong mr rallitek) that the wrx has many teeth where as the 22t sprocket has like 4 or 6 triggers on the back. you will probably have to get most of the teeth machined off of the wrx sprokets.

ok i get it now thanks bmxpunk i was going to scrap the hole idea of putting the heads on.

ok now what sproket could i use to make this all work, 2.5rs sprockests, mix and match sprockets is what i am getting at, subaru must have made a sprocket that i could use to make this work?

azn2nr · Post by **azn2nr** » Sun Dec 25, 2005 7:07 am

custom machine the sprockets. er whatever it is. and i thought wrx heads were soch not doch.

dzx · Post by **dzx** » Sun Dec 25, 2005 8:57 am

no, wrx heads are dohc. The ones i have are shimless bucket lifters

as for the wrx cam gear, i think it has 2 marks on it, i'm in nebraska right now or i would look at it. The legacy turbo gear has 7 marks i believe. I could tell you what im in the process of doing, but then i would have to shoot you.

j/k. My uncle has a friend who runs a machine shop for rtd or something like that and he's taking the legacy cam gear and putting it in a lathe to machine to fit on the wrx cams. Then i'm putting my blown block back together and bolting the heads up to it to make sure everything lines up and making sure tdc is where it should be. I'm also using a wrx intake manifold which i'm going to have to modify a little bit. The throttle cable spots are on the wrong side and i don't know about the throttle position sensor, i might have to make the 22t sensor fit it. Thats why im putting it all on the blown block first so when i do pull then engine and put everything on, the car should be up and running again in a few hrs.

I'm using phase II 2.2 headgaskets. They took me a while to hunt down because nobody carries them or can get them. (napa autozone, checkers)

ok i am getting it a little better now with the problemo, but has anyone tried to mix and match other sprokets from subarus line up to make my swap very easy.

does anyone no if 2.5l doch or sohc intake manifold work with the wrx heads on a ej22t block, i want to keep my sti side feeds in the car.

bmxpunk · Post by **bmxpunk** » Sun Dec 25, 2005 9:15 pm

Nico, I just got a spare block and am thinking of doing this to mine. But i also got a new leg turbo harness so i think I will rewire my car wit hthat, and then use either an early wrx ecu or like an autronic ecu that fits that harness.

THen I am gonna come to canada and wup your asss!!! HAHAHAHAHAHAH just kidding.

This one is gonna take time because I am going to do it all correctly.

NICO · Post by **NICO** » Sun Dec 25, 2005 10:30 pm

oooooooo shittttttt i better hurry up and get the heads on for you bmxpunk, i still need a intake manifold, light fly wheel, stronger clutch, and THIS DAME TURBO problem.

bmxpunk · Post by **bmxpunk** » Mon Dec 26, 2005 2:00 am

hahah no hurry mine is a "long term goal" Short term I am thinking of getting rid of the bucking that my car is doing.

I am still trying to find a 16G for a wrx since I already have the compressor side housing. then if I do switch heads, I can just switch over the ousings as well.

Besides I thought you were pulling off sti's already.

I m working that direction, but with my bucking, i think i am a hair under a stock wrx right now (only 8psi too)

dzx · Post by **dzx** » Mon Dec 26, 2005 4:54 am

the 2.5 dohc sprockets have magnets set into the plastic to complete the reluctance circuit. I don't think they fit tho

NICO · Post by **NICO** » Mon Dec 26, 2005 11:26 pm

so 2.5 wont work dame, dear lord there must be a way show me the light.

bmxpunk i can beat stock stis, but when pepole have work done to there cars more then me they will beat me just bye a bit.

i want full out speed where i cant slow down with my new 4pots 2pots, i want to light tires on fire in any gear just bye taping the gas.

dzx · Post by **dzx** » Tue Dec 27, 2005 1:09 am

get a supercharger

check this out.

NICO · Post by **NICO** » Tue Dec 27, 2005 7:27 pm

me and my dad where going to do that long time ago, i have that supercharger sitting in my shop but there was to much work to do, and i need to use my car to go to work. but i still need the wrx heads on my car for more flow.

i byeing the tdo5h-16g from deadbolt this month, do you guys think i need the wrx heads on it, or it will be ok with my stock heads? i payed 250 bucks for the heads so its not a big loss.

so if i just grind off the teeth on the sprocket to as many as my legacy turbo has it will all work perfect.

bmxpunk · Post by **bmxpunk** » Tue Dec 27, 2005 7:58 pm

The 16 should do quite a bit.

if you want o sell those heads or if you find a deal like that again let me know.

Did you get the intake manifold and everthing for them? Your leggy one isnt gonna fit

NICO · Post by **NICO** » Tue Dec 27, 2005 11:19 pm

you no what bmxpunk i give up on the wrx heads, they dont come with the intake manifold, just the heads and the sprockets and everything inside them. i didnt bye them yet becuse i was going to this week but thats it to much to do. here is where you can get them

i have a new plan there is a guy in my city that works on heads, im going to send my extra ej22t heads in and get the vavles bigger and a crazy cam re-grounded to make more power, then i will have a 16g slap it all togther and hope its insane fast. what you think?

im going to change the name of this post to, so pepole on this board dont think that its wrx head swap is going on.

bmxpunk · Post by **bmxpunk** » Wed Dec 28, 2005 1:12 am

Dude thanks nico.

Hmm bigger valves and stuff....

That sounds kinda good. damn it nico!! hahaha

any buddy have any ideas as to what size valves to go to or how big we could go? Then what? port and polish everything.

can anything be done to the combustion chamber?

uh all of that with a 16G... ooohhhhhhh sweet.

NICO · Post by **NICO** » Wed Dec 28, 2005 8:51 pm

i need help with this project, i got a guy who can do my heads but he does not no any specs on my heads for bigger vavles and re-grounding my cams does anyone now where i could start off.

also should i just do my cams or do the vavles to.

what heads from subaru could i get that will last long give me more flow and not put a hole in my pocket. or will not blow up under a shit load of boost

bmxpunk · Post by **bmxpunk** » Wed Dec 28, 2005 9:11 pm

nico, i have the specs for the delta cmas at my house,

i can post them after I come back from my lunch hour

Impregacy · Post by **Impregacy** » Thu Dec 29, 2005 12:32 am

what about the European/Japanese twin turbo legacy engine -that had DOHC -maybe you could use those sprockets?

NICO · Post by **NICO** » Thu Dec 29, 2005 8:17 am

bmxpunk with your specs is it the max i could go with out blowing up? i want something like in that line you now what i mean right hahahaha.

Impregacy all i need is the right part number so i can just go to my cuzin at the dealer ship and say this is the # for the sprocket i need to make the wrx heads work.

if we had part numbers on every single thing subaru made i would make a subaru rocket ship from hell that i would be scared to drive.

does anyone now if 2.5l sohc heads will work and the sprocket problem, i can get a hole blow motor for 250 bucks.
