I figure if Honda can make 100 hp per liter, well damnit SO CAN I! I´ve decided, when I rebuild my engine I want to raise compression, add some AEM Adjustable gears, more aggressive cams, bigger valves, and custom JE Pistons. (among other things) to make my car hit 180 hp Naturally aspirated...or if i bore it to 2.0L I want to make it hit 200 hp N/A. I´m pretty sure I´d keep my Power steering but I´ll prolly get rid of my AC. :-D

have fun... the potential just isn´t there unless you invest ALOT of money, which in the end could have been spent on something that could yield better results, such as a turbo... If you are going to go all out, after boring it out stroke it too, thats where you will probably find the greatest gain... Theres no replacement for discplacment ;-)

its possible, but the secret is in the stroke. If you could get stroker crank spun to provide just over a 4.0" stroke...you could find alot of power that way. The second place is in the head.

or forced induction. 180hp isn´t hard.

 

[siragan]

I´d personally just force induct it, but still, sounds like a cool project.

But how about torque...?

Dunno if you could stroke the engine any more. It´s basically a 1.6 stroked to 1.8. So you might be limited there. But you could probably get away with a bore job, increase compression via the head/pistons, and have the engine balanced. You´d probably need to switch over to solid lifters as well since hydraulic lifters wouldn´t work in the extreme upper rev range. Also, you could ditch the stock intake manifold (thing with the VICS system). Swap in a set of tuned trumpets each with its own throttle body and plenty of access to outside air - this from a hood scoop. Since your intake is at the back of the engine bay and in the middle, a center mounted scoop would work here, or a cowl induction hood which would look cool on an escort. You´d need custom programming to handle the 4 butterflies since the VAFM would be gone. It´d be expensive, but it would be naturally aspirated. Like Blade said, it´d be quicker and cheaper to go turbo. But I understand the desire to have something exotic.

 

[James92Scort]

Yes Zeemax, I want something unique, I can get a cheap as f**k turbo off my sisters new boyfriend and his shop, but I think I want my gas mileage to go up for a while...yeah i´m sick of 15 mpg all the time. I want 180 N/A and to at least make 25 mpg. I know it´s expensive but anything having to do with "rebuilding a car engine" would be expensive, no matter which way you go with it.

I was just gonna bump but I thought nah I´ll use my posts :-]

 

[Trashknight]

I was wondering, could you do all of that stuff like boring and stroking it and then turbo it? I didnt know if you could still do something like that or if that would just be too much for the car.

 

[James92Scort]

You could bore it, stroke it and rebuild it, but to turbo it you´d actually want to lower the compression to about 8.4:1 or better 8.2:1, and retard the timing, a lot. This will prevent knocking since our cars never had "anti-knock" capabilites. Which is why I´d think a WRX engine would rule in this car. When I rebuild my Engine I´d like to shoot for a compression ratio of 10.5:1 (up from 9.0:1 in stock EGTs), put in agressive cam profiles, new rockers, and new valves to hit 180 hp, N/A.

 

[92gt5spd]

phew, i know if i tried to get 10.5 on my car, i´d get nada but trouble. when i got my engine retimed, it left a gay crappy predetonation rattle when i punch the gas and the idles arent high enough...I think that would make my car burn valves and shoot rods like those little estes model rockets....lol

 

[James92Scort]

That´s why I´m having my car rebuilt. it just doesn´t perform like it should, and I worry about it when I´m pushing it hard.

 

[BlackMx-3]

Why would you want to lower compression? Yes its more boost friendly, but higher compression would yield better results just be harder to tune into spec... A turbo would actually give you better gas mileage than an all motor setup if you used a large turbo so that you could keep your rpm´s under 3 grand without boost therefore better gas mileage... I find it hard to believe that your only getting 15 mpg... My car gets 25 mpg and they are very simliar.

 

[James92Scort]

Lowering compression prevents knocking. I don´t care if you don´t believe me when I say I only get 15 mpg, I know I do, and i´ll leave it at that.

 

[Scortadict]

if you only get 15 mpg, something is wrong with your car. maby the o2 sensor is bad?

 

[James92Scort]

maybe. it could be a ton of things. I usually tend to keep my scort centered at 3000 rpms during normal driving. Thats where you can really feel the power surge start at. my brother used to do this with his old Civic SI and he could still get around 25 mpg + with that car. But, I dunno. it could be anything, fuel pump, lines, injectors, plugs, O2 sensor. I know it´s not the exhaust pipe or the intake tube because they´re both brand new.

 

[ocorzo]

James,

You would only want to lower the stock compression if you are planning to run high boost, say over 15psi. the stock 9.0:1 is not bad if you stay under 16psi. and BTW the EGT engine doesn´t have knock capability because of the engine management that Ford used, though it really wouldn´t be necessary. You could always buy an after market knock sensor and controller.

 

[James92Scort]

technically you´d want to lower the compression to run much of any boost, to play it safe. I know I would after I spent a couple grand on rebuilding it, because I´d rather not put a brand new connecting rod through my block. 9.0:1 is high for a turbocharged car. most cars you see out there that have a turbo from the factory run a comp. ratio of like 7:1 to 8.x:1. I´d like to reach for a 10.5:1 compression ratio and see what kind of power that gets me N/A. think I could hit 180 hp? I think it´s possible.
