i cant believe no one has any suggestions on this one he had the 92 legacy for the first season won 9 out of 22 races 20 lap features with 6 or 8 hot laps the only comp we had was an old school acura w/b18 PnP heads and manifold second season built a dohc 2.5 put in 99 awd 1.8 impreza gutted the awd used a 2.2 tranny killed everyone crushed acura biggest prob was we were spinning all the way around the track 1/3 mile high bank clay. the 4 cyl class took off then 30 cars a race ppl started sayin we were cheating w/a 2.5 so they booted us out then we swapped the 2.2 into the impreza got away with this one did so so mind you no other car got teched. we are just tryin to get some extra torque out of the 2.2

He would have to talk to Bill at I-Speed to see about getting a reflash. There are reflashes available for N/A imprezas. Ive got one for my bugeye! Check out their website.

Those only work on the 99 and later EJ25, right?

^^^Yes but I was letting the OP know that he could contact Bill at I-Speed who may be able to work something out with him.

We tried to get an I-Speed reflash for the EJ22 going....it seems it's not possible.

To the OP: What are the rules for engine management? I'm sure you can get some sort of programmable EFI on it (megasquirt FTW) and keep it cheap. Another option would be to use a WRX ECU and then use romraider to tweak it for NA use. Make the timing curve work for you. You'd have quite a bit of wiring work to do....but it's possible.

The FSM shows that the early EJ18 got a slightly more aggressive cam than the EJ22, so swap them in along with the rockers for a slight bump in power.

And for christ's sake....use some punctuation. I didn't reply before now because I couldn't understand the first post AT_ALL.

Understood. I wasnt sure if anyone tried to contact Bill about that or not.

didnt realize i needed an english degree for a reply. thanx for the info prob try the cam swap see how that works..... as for rules of the races the cars are suppose to be stock , but everyone in the class runs a k/n or open element filter and of coarse everyone whacks their mufflers off. they checked our vin on the impreza matched it up and said we had to run the engine that was originally in the car ahhh a 1.8 i dont think so. we put a 2.2 in the impreza and the dummys didnt know any different. other rules are car had to come stock with 14 inch rims , rollcage nothing specific about those just cant tie front strut towers into the cage. very simple cheap racing.

Interesting - the 1.8 Cams would bump the power?

Also, I know that the ECU from a 98 RS will work on the EJ22 - is that a reflashable ECU?

Yeah, but only the early ones. I don't remember what year the cam profile changed....and the rockers have to stay with the cam.

The 98RS ECU is not reflashable, but I can get a different rev limit if needed.....up to about 8125 rpm before drivability becomes an issue.

Kinda odd to be thinking of ways to cheat the rules as the community is normally doing everything we can to stay within the rules. It's too bad the VIN isn't for an Impreza LX with a 2.2. In that case, I would suggest the phase II motor and a few more opportunities for power, both legal and not.

well everyone running up in the front does motor work ie.shaved ,heads bigger valves,and im sure some unseen mods..these other guys take it pretty serious they are the ppl that cant afford to run a 358 modified or brp/street stock cars. big nascar fans.lol.they dump like 2g in a junkyard fwd so they can win a 3ft trophy.we are cheap scates tho . the only reason he runs a subi is bc he works on my dd 00rs . i took him to perryspark rallycross and showed him that i could rum at the top against way faster cars. so what you are suggesting is an early 1.8 cams and rockers? any specific year?

Get the FSM for older Impreza's. In the specifications section, the cam specs are detailed. I don't remember off the top of my head which year to look at, but it's before 1996. Another option is to pull your cams out and send them to Delta Cams for a regrind.

While you're at it, pull the heads off and shave them .010" for a little more compression. If you wanna go all the way with a cheater motor, have the EJ18 bored out to the max oversize for an '01 EJ22. Your CR will go way up requiring race gas....but it should run like snot!

I just re-read the first post....the car already has an EJ22, right? In that case, forget the EJ18 cams.....find a phase II motor ('99-'01), do an overbore, shave the heads and put a set of SOHC EJ25 cams in it. Keep your old throttlebody and engine wiring harness to make it all work. Shave the locating tabs off the newer injectors so the old plugs clip on and go to town. Send me your ECU and I'll give you a 7500 RPM limit for a small fee.
