Forced Induction Another Ebay turbo kit...

*NEW* Corolla specific turbo kit on Ebay

http://cgi.ebay.com/ebaymotors/2003...ryZ33742QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

thats pretty damn cheap

kit looks decent but this guy either have huge balls or is is a moron. 8PSI and using nothing more than GT-S injectors for fuel management.

/\ sucks for us lol

whos happies713?

for gods sake, greddy, hks one of the GOOD companies, just make a goddamn kit already, they make kits for the fuckin XA and XB but no corolla

see thats why I'm having travis build mine...

see the only engine I'd swap to is eather the 2zzfe or the 2jz but thats not going to fit... and I'd still turbo it

Another Ebay turbo kit...

Huh, $1500... He's not using an engine management. Can you really run without a FMU or engine management? I wonder if that would cause any problems...

...interestingly cheap.

There's no way that kit is going to work without some good engine management. Ask him why he took it off his car...

Merged.

I guess flex pipes dont exist where he comes from.

you know, looking at that ebay listing i was wondering something.
(hang on with me, this is gonna be a long post)

i read the manual tonight and realized that it might be possible to run turbo with just injectors and a different MAP sensor.

the 1zzfe has needs these basic sensors to run:
MAP
knock
Camshaft A.S.
Crankshaft A.S.
oxygen
TPS
IAT

all of these supply the ECU with information to control the timing and injector pulse width.

the only things affected when the motor is in boost are the MAP, IAT(conpressed air is hot), and the knock sensor.

the IAT is good for at least 174 degF according the manual.
the knock sensor should cause the ECU to retard timing if it feels knock. the ecu should relearn the timing curve based on these 2 sensors.


the oxygen sensor is really unaffected by boost and should perform the same either way, so the MAP sensor is the main sensor that is responsible for controlling pulse width.(the others only have a small effect)

the current sensor maxes out at around 4V-5V(this is when there is no vacuum at atmospheric pressure). anything above that, and the ecu will throw a code and the car will not run above a certain manifold pressure.

if we install a 2 bar MAP sensor, however, it would read 5V divided by 2 atmospheres or 2.5 volts.
at idle the stock sensor would show .5V, so the 2 bar would show 0.25V.

now the problem becomes that the ecu thinks that the pressure is 1/3 of what it actually is, so the car runs lean. this is very bad, but it can be corrected by using appropriately sized injectors. the stock ones are 265cc, so you would need to find 530cc injectors(or most likely 550cc because you want your AFRs to be in the 12's-13's) theoretically this should work. however i do forsee problems with this setup.

1) the TPS sensor would still be configured to show the stock output. this sensor has a slightly larger effect on the fuel curve then say the IAT, but at WOT it can make the car run at bit richer which could make it bog down.
2) the ECU might not be able to retard the timing enough to support higher boost levels. even though the sensors are telling the ecu to cut back more advance. the problem is that the ecu thinks that the pressure is less then it actually is, so the timing is by default advanced (at low pressures, the timing curve is more aggressive then at high pressures)

tell me what you guys think. the honda guys tried it and it seems to work just fine. i think this might actually work on the corolla with MAP as well.

heres the linky:

*EDIT* if you notice all the talk about a whacky timing curve, this is probably because hondas dont have a knock sensor like we do. also, their map reads 3.1V at atmospheric. that is why theyre using a 3-bar sensor

so lemme know that you guys this of this.

Well first of all, this kit was on an '03 Matrix which also has an AFM.

And if the ECU is programmed to read .5 volts at idle and one day it wakes up and starts reading .25, I don't think it's going to be happy... but you never know till you try it...

-Doc

it's gonna think your vacuum is really good
btw i wasnt referring to a matrix running this turbo kit, working like that. i was just thinking it would be possible on a corolla, thats all

but if you consider what youre doing when you plug in a pre-programmed emanage with 550s and a greddy pressure sensor, from the ecu's point of view, its the same thing(really high vacuum with larger injectors) *i think it runs because its in closed loop mode? not quite sure* i really want to see an emanage fuel map from someone who's running ~550's and the pressure sensor. if their fuel settings are -20% at idle, then i think the 2 bar sensor should work just fine.

if no one has any ideas about his, i'll call TRD and ask them. if i get this to work, i'll let you guys in on the injector and MAP specs so that you can run a cheap turbo setup

you know why they make all that shit for the ITS and the XXb its because they were so big in japan that they figure they would make a shit load of money by making all these products before the car even came out in america did you notice how fast products were out for those cars everything except body kits. but seriously the major compaines do need to start making these same products for the corollas

...iSt/xA and bB/xB.
