Talking 1.8 Liters of FUN!

I was wondering if anyone knows about headers or hi-flow cats for my 93 Impreza 1.8? My car is actually pretty quick considering 110 hp + Intake. Im mainly looking to get some easy gains for a moderate amount of $$$.

I know about pulley kits and things like that, but all I ever see them for are the 2.2 or 2.5.

Thanks
Benny

If you check the FAQ in the "conversion" section you may find some goodies.

I think he was referring to the MAF based EJ25 as in the whole 2.5 liter engine. the MAF based ej25s bolt right in and all the plugs match up.

Any exhaust part for an EJ25 with work for youre 1.8. pullies also work on the EJ18.

Im not sure about getting a motor swap with this car. I just want a bit more power and looks. When it's finished, I want to keep it and buy a 98-01 RS.
So if I bought a header for a 2.5, it will golt up to my stock 1.8 heads and cat?

it's finished, just go for the RS already.

seriously, how fast do you think you're going to make it?

maybe if you stripped the interior and added every single bolt on possible you could break the 15s... but without going nitrous, f/i, or swap i don't see your car being at all fast.

is this your first car? i thought my first car was fast. it was a 3speed+OV Automatic Mazda 626(N/A, not tourer GT turbo) from 1989.


suprise suprise, it wasn't fast.


check out borla headers, they say they bolt up to 1.8, 2.2, and 2.5 liters all the same.

My main focus right now is the RS Exterior conversion. But I would like to get a haeder pulley set and hi-flow cat. Thats really it.

If anybody know of parts I might need, please let me know.

EJ18 fast? No. It will never be fast but you can make it a little more peppy. I have intake, exhaust, underdrive pulley, and soon to be headers. The car is a little more fun to drive now.

Thats exactly what im looking for. I have intake. Where did your exhaust come from, what kind? I bought a stock 01RS catback but it didn't bolt up right.

not fast. When i sent my bronco to the junk yard and bought the ej18, i thought it was fast too. but then after i bought i realized i was just driving a very very slow bronco.

i thought there were no headers available for the ej18.

but anyways, nothing you do will make your car fast. except for an engine swap. save your money

I can keep up with stock EJ25's. 97 Legacy Outback to be exact. Well, before he bought a header. Dont they have 165 hp stock? Though I do have a 2.2 Legacy Turbo Tranny and a brand new Luk Clutch.

Scooby drew is right. There is nothing you can do to the EJ18 to make a dramatic increase in power except for an engine swap. I have a 2.25" intermediate pipe bolted up to a 5Zigen axle back. My headers will be going on soon.

Really, dollar for dollar you are better off sourcing an EJ25 from the FS forum and throwing that in. There are so many RS owners doing WRX swaps they are almost giving the old motors away. Never mind about the exterior mods. You want it to look fast, or go fast?

I want to look nice but go fast also. I dont want my Impreza to turn out like my friends Civic that looked like hell, but was fast.

Some bigger wheels, and an RS wing make all the difference in the looks dept.

I know everyone has already said it, but an engine swap is the way to go. Why spend hundreds of dollars to get maybe 5hp more out of a slow engine? Save your money and do a swap.

Or you could buy one of these:

I'm sure it could be adapted to the 1.8 somehow. But it may make your engine explode. I guess then you could say your car is "finished" !

HAHA! for that price, you can do an EJ25 swap and mods and have just as much HP as a turbo 1.8 with more reliability.

Hrmmm I would say it depends on what your goals are and of course budget. I would tend to agree with most people here in that a swap would be cheaper and more effective in the long run than fixing up the 1.8. I, myself, will be looking into swaps in the future when money is hoarded. If you are going for the swap though look at all your options and pricing, because if you can get an ej20t engine for not much more than an EJ25 that would be the way to go. If you don't mind spending a tad more then the ej25t engine is definitely a good choice Your car would be a monster. I am not aware of any difficulties with these swaps though, so I could just be blowing wind.

Main point: Look at all your options and pricing, before doing a huge job like that. I think I will end up with a built motor, because I want a reliable engine that can handle a T67 without problems.

*note the ej25t and ej20t are just references to the turbocharged versions I know they have different names like ej257 or some crap but I am too lazy to remember every detail*

Just to let everyone know, I dont have AWD. So doin a motor swap would only spin the tires more often.

Or, you could buy my EJ25 AND AWD conversion stuff. Your car would be very nearly as fast as a WRX in the 1/4 and could blow it away in short acceleration runs.

From what I heard and read, AWD conversions are more trouble than their worth. Telling me I should just go buy an AWD. Though how often does anybody here about a motor, tranny, and AWD stuff for sale less than the difference of buying an AWD Impreza?

From what I've read the only difficulty is replacing the gas tank, and you may actually have an AWD one in your car already. That would be TBD. The rest of it is purely bolt-on, no fabrication at all. As far as how often do drivetrains come up for sale- well, mine is available. I'm looking for $2000 for my EJ25, gearbox, driveshaft, rear diff (viscous LSD), halfshafts, crossmember, STi Group N tranny mount, and hub carriers. You'd also get the shift linkage and related parts including knob and possibly the clutch pedal/cylinder/slave assembly. The engine is complete from intake to exhaust, and includes engine wiring harness but not ECU, although I can help you get one cheap. I also have a lightweight flywheel/clutch from Exedy that I'll give up for $400 with everything else. Since we're both in California, getting the stuff to you wouldn't be a problem- I may even be able to deliver it to you. I can probably even get you a great deal on installation. PM or email me if you are interested in more details.
