N/A Build !!

[Gabwone]

Hello guys im new on yarisworld but had my echo for a year now ... I would like to build an n/a 1nz-fe high powered close to 180hp ... I got pretty much all the bolt on for it right now c.a.i , headers, exhaust + Borla catback , koni yellow shocks on apex springs lowered 2'' with enkei rpf1 15''.... starting i would like to know what kind of management system should I use. I have seen a couple but wich one are good or bad and i would like to be able to use my power lock as well ( my only option :P ) so what i've seen so far :
-AEM EMS 4 (race car application so no pwr lock I think )
-AEM EMS 2 this look to be pretty good
-Greddy Emanage Ultimate look good but piggy back (any difference between piggy and full management ??)
-Link G4 Atom looks good too
This is what i got until now ... so any help or suggestion will be appreciated
Thank you

You have a long ways to go to get into the 180hp range.

Don't let the numbers confuse you, the EMS 2 offers more features than the EMS 4. At this point you will be nearly stand alone, or complete depending on how its installed, so its very possible you will start to lose some of the OE feature that rely on the canbus system. Decide if you want a race car or a street car.

I don't think anyone has had success with the Greddy EmU or G4.

To go on Jasons point, if this is a street car, it'll have big time drive ability problems. Given that you have a 2004 you wont have the throttle issues the later DBW cars have.

[Gabwone]

Why woud it have driveability problems ? only feature i have is pwr lock and was installed aftermarket so its not even OEM pwr lock .... 180hp was aproximate
-and you jason@sportscar what management system are you using ??
-and i want a street-race car :P nah just a faster Echo , laws here aint that strict and no smog test!!:P if its why you were asking if i wanted a street or race car !!

[WeeYari]

I have no idea how one would be able to nearly double the hp put out by the 1NZ going the N/A route.

how is your powerdoor locks aftermarket? the RS came with powerdoor locks with but button in the centre console. If you are talking about keyless entry, then that's a different story.

[Gabwone]

Illusion X ;) Club Echo-yaris quebec ;) ... the pwr locks was installed by DURO Victoriaville (some shop somewhere in Quebec) but the button is in the center at the oem place i think !! anyway i was just wondering if its the ecu's running it ? or if i will lose it installing an aftermarket ECU ?

To get that much power you'll need a big cam which makes reduces low rpm throttle, and makes the car difficult to idle. Since the car isn't being build for any specific class, I would suggest a turbo it'll be a cheaper and easier build.

[why?]

Determination :P

won't help. Now if you have an extra $100k around, you'd probably be able to do it.

[Gabwone]

100k $ loll ... Anyway turbo or n/a or supercharge what engine management you guys suggest me using !!

[xnamerxx]

EMS 4 doesn't technically support VVTI but it should work.

I would go EMS 2 though.

[Ryze268]

180 hp N/A?

I would be way cheaper to swap in a 2ZZ-GE

[Gabwone]

nah i dont really like the 2zz its not as strong as our engines ...if i would swap it would be 4age 20v black top !! but i would like to keep the original engine that was in the car !!

[ilikerice]

Your hope and dreams are not in line with reality of money and laws of physics...

Granted, we are all trying to help you achieive your 180whp goal. Turbo is your best bet with 8-10 psi. Go standalone, AEM EMS is a pretty popular one with the yaris community.

[xnamerxx]

180hp is going to be difficult because the heads really don't flow all that well and taper off before peak lift.

To hit the 180 "W"hp number you'll need the following.

High compression pistons 11.5:1+
Headwork, porting, and cleaning up the bowl
Everything in the engine coating with teflon/DLC/and anti thermal
Big cams 270+ degrees of duration
Spin the motor past 8k rpm
Rods that can handle said RPM
Long tube headers
Intake Manifold and CAI
Custom engine management
Possible run the motor on alcohol or E85

Like I said it would be way easier to do all of that with a turbo.

[IllusionX]

LOL from the local forum..

this is what was done to get 168WHP@10500rpm and lasted 20mins.. a piston pin ceased.

-Camshaft yaris cup Kronos racing
-port & polish
-pistons CP high comp (cp7447) 12.5:1
-crankshaft Knife edged :4lbs less
-lightweight polleys
-lightweight flywheel
-Valves 5 angles
-throtle bodies gsx-r750
-2zzge injectors
-headers weapon-R
-vvti delete

[xnamerxx]

That guy was giving up at least 10 hp using a shorty header.

[Jason@SportsCar]

I think you should be able to hit the 160hp range reliably, and at a reasonable cost ($10k), based on what I have seen full tilt 1.6li Miatas hit.
