What to do with my Impreza L 1.8L
Don't have the money for a swap but what small things can I do.. Is it worth it to change the pulleys? I looked at the Cobb CAI but where is the MAF sensor? can it only be put on cars with the MAP?

your MAF is the black tube inline directly behind the airbox which contains the air filter. It is bolted to the airbox with 4 bolts. you can get a MAF adapter and your choice of filter to go on for cheap, it will be loud with better throttle response with no real HP gains that you will notice. as has already been stated, borla headers (or any other 2.5L header) for the 2.5 fit the 1.8. you can do exhuast from there. Pulleys will make it rev alittle quicker and free up a few more HP. after all this it still wont be that quick, but it will be a lot more fun.

I feel the pain of the 1.8L as well. There are still a lot of things to do, and an engine swap is out for me as mine is FWD so I'd need everything redone from the engine back and converted to AWD. ($8000, I asked)
I'll say what I have with a little review so as to better educate: ~NGK iridiums, NGK wires: lowered idle, easy start, nice pick-up ~Arospeed Groundwire Kit: lowered idle, nice little performance boost at 3000rpm, seems to work well and looks good ~Vibrant Performance MAF adapter and open-air filter: (also removed intake silencer) better throttle response, louder but thats irrelevant ~2.5" straight pipe leading to ApexI N1: sounds like a rally car, very low, very loud. Boosted torque way up, gives a good kick into 2nd and 3rd gear ~Exedy stage 1 racing clutch: its a clutch, what can I say? Worry free performacnce. ~ProECM chip: with the removal of the rev limiters, I can crank the RPMs higher for better high end response. I found it made a difference in other places too, but I don't want to start another argument about this controversial little chip here. Other things are aethetic touches: tires, wheels, all my MOMO, some custom bodywork. It won't come close to a REX, but its mine and it works well enough to get a smile out of me. Hope this helps a little. Don't hesitate to ask for further clarification on anything. |

What does the MAF adapter look like? I want to really get rid of the intake box.

it seems it's only over the cone filters? and they do nothing but suck hot air in from the engine bay..

Good list of mods. I didn't have my L too long before upgrading to an RS. Had I kept my L, I probably would've done some type of motor swap by now with the money I'd have saved. I still miss my car.
Oh, not to hijack, but I'm a former Saskatchewan resident. I couldn't help to comment since its rare for me to see anyone from Saskatchewan. Quote:

Subaru likes to play it safe with the reving of the engine... on the Forester the rev limiter kicks in right at 6,500 maybe like 20-35rpms before then..
My 95 Impreza it starts at 6,000 Now the spark plugs.. These NGK iridiums.. How much are they for 4? I got a spark plug gaper and I wonder what gap size is better? I think the manual said like 0.39 all the way to 0.43 as the Max.. I want a exaust with a nice deep tone and one to punch out the boxer engine sound.. Their is this one Wrx that goes down my street.. I can always hear it before I see it and it sounds really good.. I was think Scooby Sport.. Or I was going to do the Bolra headers first.. I don't know. The car is an auto What NGK wires did you get? last time I went to their website their was not too much to do. Quote:

For the NGK wires, all I can say is they're blue. They aren't super-duper special (like a Nology, for example) but they were the ones recommended for use and replacement. The plugs were $10/e, but that's Canadian so it would be $3 for all four in the States.
The chip killed my rev-limiter, first time it kicked in before I knew it existed I thought I had seriously pooched the engine. A quick read and I was thoroughly relieved. Now I can power up to insane speeds with plenty of torque to spare. (anyone say 65 m/ph in 2nd?) For exhaust I like my N1 over the others I've heard. Compare prices, though, as all big cans will be pretty much the same and it would be unfortunate to regret a careless purchase. The Scooby sport sounds very nice, a Greddy will be the only one that strongly differs in note. Kinda gives a mellowed out bubbly gurgle and then a higher noted sqwuak under high RPM. |

SubaruImpreza_power - you can spend a lot on the EJ18 and not get a whole lot out of it. It was never designed to be a high power NA engine like a Honda engine. These are my "power" mods: - NGK sparkplugs - K&N panel filter - intake silencer removal And that's all I'm doing. It's not any more powerful, but definitely more responsive. Although that could be due to the extensive weight reducing measures I've done too. How fast do you want to spend? Buy an intake here, exhaust there, throw in some headers blah blah blah...easier on the wallet, because it's not a huge initial investment, but you don't get much power for $$$ spent. A turbo kit or engine swap is definitely a more effective way of gaining HP. The downfall is a higher initial cost. |

If I ever decided to go turbo (I doubt it) Wont I need forged pistons and whatnot?
Sure the engine swap would sound good.. I guess slavage yards are best for that.. Better to buy in the winter time.. (Crashed wrx'es) I doubt I can fit the stock 2.0l wrx engine in the 95 impreza? I wonder whats the hardest part on an engine swap? I was going to buy the new plugs last night but I was short on cash.. |

you can turbo the current motor and just run lower boost. Big issue is getting your engine management setup to run with the aftermarket turbo.
n/a motors have more timing advance then turbo cars. When you add a turbo, you really need to address this issue. If you're running low amounts of boost it's less of a problem, however everyone likes to turn up the boost, so it should be something you should look into. A relatively inexpensive solution is the torque 2 chip. It's designed to limit timing advance for aftermarket turbo installations. |

So a swap is not totally out of the question? A certain Subaru shop in Quebec told me otherwise, but that's unimportant.
If such is true, could any EJ possibly fit? I'm pretty much set up for dropping in a turboed engine with top-mount i.c., I'm concluding a brain transfer would also be required but what else if I don't need the rear driveshaft? Would I require a different front trans-axle... (sorry, if I'm hijacking the post I can start a new one if I offend the originator by asking questions as well) |

Just do a straight pipe from the headers back. It's cheap and will gain power. Don't waste your money turboing the 1.8l. Pony up for a 2.2T or a 2.5l. I've seen RS motors going for only $800 or so.

Supermoose just finished up his motor swap. he has an old FWD impreza and just put in a DOHC 2.5 from a 98'. He is running it off the 1.8 ECU. So he has a FWD 2.5. A WRX engine will fit but a lot more things are needed to do the swap(ECU, wiring harness made, New front crossmember) I think the 2.5 swap is probably one of the most cost effective things out there f you run it off the 1.8 ECU. if you get an engine cheap, maybe a few hundred bucks more to freshen it up and some new parts here and there and you have a lot more HP. I know this isnt really the answer you were looking for but just saying it so you know its not out of the question for FWD.
I have a 2001 SOHC 2.5 in my L running off the 1.8 ecu, just hit 10,000 miles on the new engine, problem free. DR.Morbid- did the chip totally eliminate the rev limiter or did it just raise it. Ide REALLY like to be able to rev my 2.5 out to 6500 or so but the stock 1.8 limiter remains at 6k. Will this proecm be a solution to my problem? |

Lets see.. I was looking last night on google for 2.5l engines.. is their really one to stay away from? it would help to stay under $1,000..
Oh and yea the size of the engine is like night and day.. when getting back in the forester sooo much more Tq. that would be cool to have in the impreza. But i'm sure more could be pushed out |

yeah its given me like a 3 sec inprovement in my quarte mile and even more 0-60. and I have beat lightly modified RSs while running off the 1.8ECU and having a 6k rev limiter. Its a huge difference.
If you want to modify the 1.8 don expect anything super fast or torquey, but you can improve it and make it a lot more fun to drive with intake, exhaust, pullies etc. and that pic... is that your tach? did you just put it in nuetral and free rev that thing?? i hope not. thats NOT good for it. im only asking cause i saw the brake light on which eiter comes on with the parking brake on or when thereis a problem and the fluid level is low. just curious. |

www.car-part.com I have no affilliation with that site. You want a 99 or newer sohc 2.5L. Play it safe and get a '00 or newer. Some early 99's had the phase-I pistons too, apparently. Pre-99 DOHC heads on a post-99 block would probably be the optimal setup for NA. Turbo just port the heck out of the head... Actually, the optimal setup would be an ej-255 or -257 long-block+clutch+ecu+harness+turbosystem with their forged rods and forged|hypereutetic (still under debate which they are) pistons, but they're brand new so no junkyard specials on 'em yet. |

About time i chimed in . I don't want to be dismissive, and a lot of u ej18 owners have done a lot of work on your cars, but the reality unless a part is in need of replacement with regard to the engine, its poor judgement to step up. Many manufacturers get big power from that displacement or less, but that engine wasn't meant for it.
if something breaks or its time for maintenance, i can understand going from oem to magnacore wires, or replaceing a rusted out exhaust/cat for a performance setup. Otherwise, u'r looking at minimal gains unless u have the ecu and internals changed. the best bang for teh buck on the NA ej18 and ej22 has been suspension, comfort, and brake mods. otherwise the rest is for show, and conversation. maybe add a few comforts here or there. But long term thinking is a good plan. u have a light body and chasis compared to the newer style. u have a FWD ej18 gm/gc. use it for a few years and save up for a transplant. for 5k u could get a wrecked GD, swap out the engine/ecu/tranny/axles. my two cents, ymmv. |

Exactly. Work on everything else BUT the engine first, then swap it out or add a turbo. Basic outline of what to possibly do to your car- Suspension: - KYB GR2 struts (pretty much your only choice for FWD) - whatever springs you want Brakes: - WRX front brakes - FWD Legacy rear disc conversion OR Porterfield R4-S shoes for rear drums - steel brake lines Engine: - remove intake silencer - change out sparkplugs - K&N or similar panel filter WRX rims with some good tires (#1 priority) You can go further with the suspension or brakes, but these basic upgrades will completely change how your car drives. New rims/tires will make a much bigger difference than an intake and exhaust. |

The ProECM removed my crankshaft rev limiter not my actual rev limiter, I played aroud last night and got spanked at the 6000rpm level. Sorry, a combination of incompetence and exuberance.
How interesting, I have GR2s with Skunk2 adj. coilovers and am soon doing a rear disc conversion with braided brake lines. Granted, the rims and tire were a much loved upgrade (stock 13s anyone?) but you didn't mention a strut bar, that really made cornering fun. For an engine swap: if going to a turboed engine the brain would also need to be included, correct? The present brain can handle another NA engine without problem, yes? What about the fuel pump, would it flow adequately to satisfy a 2.5 or should that be addressed as well? Or, as boxologist stated, would it have to be more involved and an engine swap include the engine as well as the ecu, tranny and axles for any and all? |

Morbid: People are just swaping in the EJ25's using the stock 1.8 ECU, but if you were to do an EJ20 it would be best to get the ECU as well and do a more complicated swap for sure, along with a fuel pump. The tranny and axles are not a neccesity however. |
