Default who has the fastest 1.8L FWD or AWD?

Has anyone actually taken time to do some work on the lesser Impreza models as far as peformance? I'm just wondering who did what to their car and what kind of results they got. Anyone go turbo? Post pics if you got 'em and don't forget your "tite modz list" yo.

Subachad has a Turbo. Just an XT6 turbo though, with a SAAB dinky intercooler

Ive been asking around, and the WRX plumbing for the 2.0 might fit right on the 1.8 in our car since its the same basic engine... It would require some work of course, but it might be worth a try.

I'd bet the fastest 1.8L subaru is a 85-90 Turbo of some model. I knew one guy who was running a 15 flat consistant in a XT when the FASTEST 99-00 Civic Si w/o forced induction was running a mid 16. This was at 5,200 ft or so though. Not much in mods, and it was a part time 4wd. It had a 2.5" downpipe, IC of some kind, and I think a boost controler. No hoodscoop that year so he would Ice the IC before runs. I'd bet the guy with the open class RX is the fastest 1.8L that I know of, as he fixed all the problems with the EA-82T except the crappy head design, and that is minor compared to how much lighter it is than a Impreza.

Kostamojen, the XT6 is a special model built off of a XT shell, but shareing few parts. So ALL the 1.8L XT's are just that plain XT's.

Subachad has an XT6 turbo? Are you sure about this because I'm really, REALLY interested. I gave up on turboing my XT6 and was just going to get some cams made but if someone already has the formula already done, I'm interested.

I'll PM Subachad!

Very cool Subie Gal. If my car lasts long enough until I get a better car, I'll strip it out and rallify it.

Default Impreza Brighton

Well, I have a 1.8L 1996 Impreza Brighton. I've added a K&N style conical filter, which I attached to the end of my MAF sensor, and then secured the entire assembly with some band iron to prevent it from rattling and damaging the sensor. I have also added a directhits ignition upgrade, which, after a bit of tinkering works quite well. The guy at Challenger Deep imports recommends setting the spark plug gap to 0.32 mm, contrary to the installation instructions which recommend the stock setting, otherwise you'll end up with some not so nice problems. Mine is currently set to approximately . 4 or .5, pending a smaller gap tool and a new directhits installation tool (and of course the desire for a bit of expiramentation ). My exhaust is also modified, which simply consisted of hacking off the factory muffler and attaching a motorcycle style pipe to the end, this gives it a nice deep rumbling sound. Although I do not have acces to a dyno, my performance has been greatly improved. I am also considering a few other upgrades and researching the possiblity of connecting an old laptop to my ECU's sensors in order to manipulate the signal similar to the way the APEXi S-AFC does. I am also interested in what people have to say about forced induction on this model, I have heard that the fitting of many of the WRX components on this engine (perhaps including the turbo) is possible because of the similarities between them. Questions and comments welcome.

well so far the mods for my 95 1.8 are the filter on the end of the MAS ,new exhaust,just a hair bigger than the fastory pipe,magnaflow muffler,and an unorthodox underdrive pully,i really dont want to get to involved in the 1.8 since im planning on doing a legacy turbo motor in the car so im just gonna do mods that will transfer over to the planned set up, i might try a s-afc next. but the car does run alot better with the couple things i have done,plus whoever did the timing belt on the car before me didnt have the sets points exactly where they needed to be, id have to say straightining out that problem was the biggest improvement,hmmm cam timing,go figure haha

I just have a K+N drop in, Silencer removal, and RS muffler (all free) so my car is still slow

Ive heard that lightweight pulleys are a good deal for our cars though... I need WRX wheels first, cause my wheels SUUUUUUUUUUUCK!

the night i put my strut tower bars in and had the whole back of the car apart, i figured i'd head down to orlando speedworld for a couple runs...

FWD 1.8L 5-speed sedan TiTe MoDz LiZt...

nothing in the trunk
no back seat
running on fumes
silencer removed/airbox opened up & sealed to the fender
prodrive exhaust
full lightened pulleys
a/c completely disconnected
mirrors folded in
a perfect launch
absolutely perfect weather at sea level (low-mid 50's & no humidity)

= 16.8 seconds @ 81.62

i HIGHLY doubt i could do it again...but it shows what's possible...

in normal trim, it keeps exact pace with my friend's 2.2 swapped L (intake/exhaust) coupe, and he's running very low 17's, so i'm fairly confident that in more normal conditions i'd be in that range.

Adamn,

That's a pretty good 1/4 mile time. Can you send me the timeslip info so I can post it up on my site? I have a Outback Sport with intake/exhaust/pulley/upgraded tranny...and valve body and your car would ANNIHILATE it in N/A trim. I'm running mid-18's last I've tested. My low end sucks but since I've installed a 1999 Legacy GT ECU back in, my low end has been restored. To bad the strips are down right now.

kevin--here's the infooooo...

10/19/01

16.812 @ 81.62

60' = 2.376

1/8 = 10.236 @ 68.55

R/T = 0.479 (yeah!!)

from about 3-3500 in 1st all the way through 3rd, my car pulls HARD. from 15-60mph, i have no problems keeping up with most anything on the street. it doesn't launch that well (being FWD and all), and between 70 and 90, it's kinda sluggish...above 90, it wakes up again, but i suppose that's to be expected humming along at 4000rpm.

14.3 seconds best time

MODS :

apex'i n1 exhaust , full custom cat back 600 $

I'm from jersey where the drag import scene is really hot, so I get alot of pointers from my honda buddies.

By stock time was somewhere in the 18's
These cars can be very fast , i'm working on getting it turboed in the very near future.

heheh...definitely. it really doesn't take much to turn an L into a fun car, you just have to understand that it's never going to be super fast.

not counting rims and tires (they were a necessity when i bought the car), i've turned my L into a respectable little sport sedan for a relatively small outlay (under a grand).

airbox mods = free
pulleys = $200
exhaust = $399 on closeout at mastro
cusco strut bars = about $320 for the pair from larry ganz, but they're WELL worth it. get GOOD strut tower bars, and you'll notice the difference immediately. handling improves a little, but overall difference in feel and ride quality is night and day.

haven't bothered to put a rear sway bar on yet, since supposedly they don't fit the FWD cars (?)

i dunno...i was just checking out subachad's page, and i'm drooling at the thought of a relatively low boost turbo kit...5psi on a FWD 1.8L = ~140 hp at the wheels...

racecarriot, running 16.8, i dont know who u have been racing but u cant keep up with nearly everything on the street. i only have 2 mods right no (performance wise) and some looks, but i have AEM intake and a Greddy exhaust. now im runnig low 15's and i cant keep up with most cars out there. i mean yea i had a good run last thursday at this racing point against an integra gsr with intake and exhaust. surprisingly even from a 35 mph roll (awd launch is key, but i rolled this one) i blew his doors off. then again he cant drive i dont think because a gsr should beat me or at least keep up

i'm not claiming to be the fastest thing on the road, but as long as i'm rolling and not approaching that dead spot (which is usually well above the maximum safe limit i'll travel on a public road), i manage pretty well for driving an 8 year old economy car. note that i also said "keep up," not "beat"...yes there are plenty of other cars out there that are faster, and would mop the floor with my car on the strip, but on the street, i've never been embarassed.

with that AEM intake, yes, your car can run low 15's and still get beaten on the street. you've gained top end hp, but you've also eliminated your advantage, your low speed torque, combined with the driveline loss (and weight) inherent in an AWD system. AWD isn't going to help you launch if you don't have enough low end power to get things moving.

from the dyno charts i've seen, stock for stock, a 1.8L FWD impreza, despite lacking 55 crank hp compared to the RS, only puts somewhere in the neighborhood of 25 fewer hp to the wheels than a stock RS. let's conservatively estimate that i've narrowed that gap by maybe 10hp. because of aerodynamics, both cars top out at almost the same speed. so we're looking at an approximate 15-20hp deficit vs. about a 400lb weight difference. with a competent driver at the helm, a modded 1.8 can certainly give a lesser driver in an RS a run for their money. an RS is a quick car. quicker than many you'll come across on the street. if i'm not that far off the pace of a stock RS, it stands to reason that i could also certainly make an example of other cars on the road.

sure, someone may be faster...a lot faster, but if they're caught off guard because they underestimate their opponent, that's their own damn fault.

and yes, there are a lot of people out there with very fast cars that just CAN'T DRIVE.

its a 2.2 liter AWD

Well without the NOS its about a 18 or 19 second car, stock.
With just the mods {excluding NOS }
its about high 15's, low 16's
which is still respectable

I'm working on getting it down to the 12's
but we'll see
the great thing about this car is that when i first got it everyone said it was slow, { which was correct } but i love going against all odds and turning a slow car into a fast car is what i live for.

So im planning on buying a 95 2.2 liter awd 5spd coupe from a buddy of mine!
can you guys give me a idea of stock1/4 mile times, and then with, cat-back exhuast, cai, headers?

Also what else including these items would i need to get into 14's?(besides nos)

Thanks,Jason

stock...in a best case scenario, probably high 17's...

an intake and exhaust will get you into the afforementioned low 17's.

14's? turbo dat suckah!!

WOW...there are actually other 1.8L FWD owners out there? I was feeling so...alone. All these RS's and WRX's...made me feel like a sixth toe. We should petition the Prez for an L forum...I'd subscribe.

On the lack of power issue...we all know that we're not going fast anytime soon. However...I'm going to put lots of time and loot into making it handle right. I don't do rally...but I love the street twisties...and with some hard work and help from my friend who is a master mechanic...I'll be smokin' some of those AWD guys on anything with a decent amount of turns. Straight line racing is not an option...:monkey:
