Default How to be competitive for cheap in autoX with EJ18

Okay, so Im saving my pennies for a EJ20 swap after I finish school, well not saving, but you know.... I want go out and autox again after a ten year hiatus, Ive got an EJ18 powered Impreza Brighton with WRX wheels and a suspension uprgade (just all the bits from a 2.5RS, OEM) that puts me in DSP....one problem--> 90HP....what can a brother do on a low budget do get a little more power. I dont really care about winning or anything, but I get tired of bog...I dont even want to know what kind of "torque" im making, and I'm getting some better skins no matter what (if i dont have to slow down as much, I dont have to speed up as much ) Engine has 150K, but I keep it up well.
Any recommendations? underdrive pulley? exhaust?

I'd say just go with suspension goodies and stay in STS. You'll be plenty competitive there... It's a good place to learn too.

strip the bish!

power is not everything in auto-x. it's usually too tight of a course for big power to come into play. that's why most courses don't get out of 2nd gear.

your numbers are 110/hp @5600rpm and 112ft/lbs @4400rpms. And yes you have no power under 4000 rpms. I know because I have the same problem. I upgraded my wheel package to some gold 15in rims and I noticed a huge acceleration loss..of cource bigger wheels meansfaster top speed slower acceleration. I plan on buying a parts legacy next week and replacing my EJ18 4EAT with a Ej22 5-speed. Cheap thing to do because parts legacys are easy to find. BUt if you don't have any Mechanical know how...probably not your best option. I plan on taking my 1.8 heads and puitting them on the 2.2 to increase the compression and get a little more hp then your stocker 2.2. There isn't much you can do to th 1.8 unless you plan for a swap or loads of monies for a compressor....Nitrous isn't that expensive .

on my ej18 i had a stromung cat back, and put a k&n panel filter in and cut the box right at the bottom of the filter. the car sounded pretty bad ass, and the throttle response was a lot better. i also gutted the second cat but im not sure if that really did much at all.

gutting the 2nd cat will only let you fail the CT state emissions testing program at "cruise"...

Luckily he lives in Nevada, where such silliness is not tolerated.

If you wanna start spending cash, here's where I'd shell it out:

1) Borla header, custom straight pipe, and catback. 2" piping all the way should be fine, although the Borla does terminate in a 2.25" flange.

2) Lightweight flywheel and mild clutch upgrade. This won't work with a WRX transmission when you do your swap, however.

3) Bigger sway bars. Bigger is pretty much better. Whiteline 22mm adjustable front and 20-24mm adjustable rear, with endlinks all around, and mounts for the rear would be great.

4) Real suspension, i.e. coilovers. You can spend oodles of money here, but you can get by with something like KYB AGXs and GC sleeves around 300 #s.

Yeah, live in NV, but I still register in California ( residency issue for school). I simply wont gut a cat... Id sooner buy a better cat, as I probably will stay reg'd in Calli. Borla makes a header for an ej18?or is it the same as for an ej22 or something? where might i find one, and is there anyone youd recommend for the custom pipe fab in reno? Any feedback on the underdrive pulley? does it free up enough power to be worth two bills?
Borla is among the quieter of the exhausts is it not? thats what i like.....no rice-Im a cornfed boy!!

For reg purposes, just keep your stock catpipe around and fab a new straight pipe from scratch. The Borla headers make any exhaust sound better without making it louder. It's the same as the EJ25 one actually. There's a muffler shop over on Galenda next to Pat R.'s shop in Sparks. Mr. Muffler Mike's Muffler or something like that, they've done stuff for a few people in Reno that autocross. As for mufflers, I just have a Magnaflow that I bought used and had the pipe fabbed around it at Subaru Specialists. Make it out to a meet and you can judge how it sounds for yourself.

You can get a pulley for under $100 actually. Go with a lightened, but not underdrive one to ensure you never overdraw your alternator at low RPM. I haven't done one, but that doesn't mean it won't be worth it.

Sell the WRX wheels for 15x7 or wider wheels that are as light as possible. Think slipstreams or subzeros. Wrap them with 205/45 or 225/45or50 tires and get proficient at shifting to 3rd gear. Coilover sleeves on AGXs with 400+ springs f/r and a good set of big bars. Get all the weight out of the car that is legally allowed. If you have power locks or windows, see about swapping for manual type. Intake is just like the RS....snorkelectomy and fender mounted cone setup.

The above exhaust is good, the Borla will fit. DO NOT pay $200 for pulleys.....Too many others on the market to justify that BullShizzle. They offer some gain...but no wheel-scorching power gains.

I was able to be competitive with "mildly prepped" RS's in DSP with my 96L that was also "mildly prepped and wildly driven". Had I been a little better prepped, I may have taken the car over more RS's.

I have some ideas that may help Imprezas get alot more competitive.....but I'd like to try them first before suggesting something ludicriously wrong.....the ideas are kinda unorthadox......

Yeah, borla does sound like the hot ticket....My dog is a Brighton...meaning it is probably the lightest awd Impreza ever, no nothing, just a/c and a stereo. stoked on that. Ill get more of a picture after I go to the next autoX and see just how crappy my skills have gotten, but I'm sure Ill do well enough to have fun in my $5000 car.....
The pulley advice i likey, didnt think of the lighter-no underdrive thing.
Snorkelectomy---you mean make one from abs or something or try to track down a injen....?

My 96 beast is titled as a Brighton, but didn't even come with a brighton badge. AC, power brakes and steering....that's it for creature comfort.

I'm still using an old JCSports underdrive pulley with no adverse affects. Our Toyota Corolla lights dim more than my Scooby lights at idle in the dark......yet another internet myth.....

The snorkelectomy is the removal of the guts inside the fender. I ended up using a Rallispec intake, hung my MAF on the end and ran some 3" naca duct into the fender where I secured a decent cone filter. I tried using a "torque box" from a stock 98RS....but like the current setup better. The 1.8 is loud without a muffler. If you can stand it, decat the car and hang a decent lightweight muffler on the end of a straight 2.25" exhaust.

The biggest problem for me was the low rev limit. 6k is just not enough. I don't think the cams are falling off yet as the motor actually seems to be responsive right up into the limiter. Keep it up there and control the handling with as good of components you can afford. If you can do anything to raise the revlimit, (PM me) a good valve adjustment will allow that motor to spin pretty good. It's very much de-tuned. You gotta think light in order to be cometitive. Stock RS stuff isn't gonna cut it if any halfway decent DSP car shows up. I had to drive my arse off just to stay within the trophies locally. Bigger events were just a joke. The 1.8 actually goes to FSP now....so you have some chance unless IT prepped rabbits show up.....

The front bars are the same as the RS. Go bigger if you can afford the few front bars for the GC. You can get an MRT rear bar setup that locates the links on the trailing arms to quickly add a rear bar (WRX would be a good start)
to control that dreaded bodyroll. Everything else bolts right up from the RS and taking suspension cues from the competitive GCs will put you in the ballpark.

You can run in HS if you wish, might be more competitive there.

But in ST-S, you cant keep up with RS's, since they are basically the same car as you but more power (and low end power at that )

I know this from experience...

HOWEVER, my last L was competitive to a point (not against simularly equiped RS's, or well preped wrxs, and not on fast courses...) and it was set up like so:

4 point Harness (IMPORTANT! Trust us, harness's make a huge difference during autox)
Rota Slipstreams (16x7, +48 offset, 13.5lbs)
Khumo MX's 225/50/16 (rolled fenders)
WRX front brakes (RS Calipers)
RS shift linkage w/ Kartboy shifter bushing + Cobb shifter + Leather boot + WRX shift knob
Custom tranny mount (Eurathane filled)
KYB AGX struts w/ Ground Control Springs + rear camber bolts
Cusco rear crossmember brace
Modified 2.2 Intake box
Mr. Josh Pulley (had an unothodox underdrive pulley before that, and yes the underdrive makes a BIG difference for the 1.8l)
Borla Headers
WRX muffler + custom midpipe + straight pipe muffler for autox
WRX sedan rear swaybar
Eurathane front swaybar bushings
Eurathane rear swaybar bushings
Eurathane Steering Bushings
Eurathane Differential Bushings
STI front control arm bushings
RS rear control linkage/swaybar mounts
Kartboy rear endlinks
Whiteline front endlinks
Whiteline rear control link set
Kartboy Exhaust hangars
OMP rally pedals
Rear Strut Bar
Front Strut bar
Lightweight Battery

Some of those mods might put me in different classifications, but like I said, I couldnt keep up with well equiped RS's or WRX's anyway with the 1.8l engine...

I was doubtful that I would be legit in a stock class with all my susp "mods" if you call them that. from the rulebook, I deduced DSP......

Yeah, Im not afraid to be outgunned, Im not trying to win...yet. Im gonna look on that fsp thing, didnt know....
Definitely going to look into the snorkelectomy....i need it from wherever i can get it....will probably californize the exh suggestions though (dummypipe?) or will most likely go the borla route, ill misuse some student loan cash and perhaps obtain WRX bars, theyre bigger right? (from the sedan) Im a pretty poor boy, but....
got any pics of the snorkelproctology?
damn rabbits make me look bad...........

FSP is empty in Reno. And you'd be running Street Tire, so they wouldn't be competing with you anyway, and you'd have an awesome PAX for the class. I finished 3rd on sunday thanks to TDSP being .020 better than TSM.

PAX is the multiplier for your time to equalize all the classes. It's how we all compete in street tire together as one class while being in different classes for mods.
