Look to the states, they had fueel injection for asllt he 90's model samurai

if you can get wiring, ecu, manifolds and tbi for $400 its better than piecing it together from bits, considering they all go extractor + weber etc its not that uncommon on US ebay, just be patient for the complete setup

[BlueSuzy]

Don't diahatsu models have TBI too for their baby motors? Also Lasers kh/kf 1.8i are tbi (i think) NOT the twin cam tx3 etc..

[2stroker]

Yep and there are 100's of those mid 90's Barina Swing's in wreckers, they are 1400cc so the TBI should go nicely on a 1300 zook, I think some early Pulsars, Lasers had TBI as well, heaps of them around and very cheap.

[31zook]

yeah i bloke at work has a barina and it's 1400 + TBI... i shall start my wreckers hunt this week

[BlueSuzy]

was your block bored? Original 1298 or 1324? (most likely 1324 if original)

[31zook]

you talking to me timmy? if so, yer it was a 1324, the bored out 40tho... why do you ask?

[BlueSuzy]

Just wondering if it was oversize. So fueling might work out equal to other 1.4 motors etc

I saw a 1.3i Charade the other day.. Pure powerhouse..

Fueling will be off anyway due to the difference in the volumetric efficiencies of the engines. Most likely run ok, no guarantees. If they have a closed loop system ie oxy sensor this should get the cruising AFR near spot on.

Yeah i knew there would be abit of difference in the 'volumes'. I just couldnt work out how to explain it.

At least if the capacity is close, The ecu might be able to adapt to what it needs fuel/ air ratio etc.

This is part of the reason i went with an aftermarket managment system. I have done the swap onto a 1.3L using a standard 1.6L ECU. Using the factory o2 sensor etc the closed loop AFR was quite resonable, but open loop it richens up too much.

If any of the Newy guys want a hand with a conversion let me know. Im flat out till TTC, but a few weeks after that i am happy to help out if you want a hand.

Layto....

[31zook]

layton, i shall be PM'n you when all pick up all my stuff.. won't be for a while but will happen

Um yep, ill be looking for a barina 1400 TBI setup. So if any of yall know of a TBI setup thats not needed shoot me a pm


Um is closed loop meaning that the fuel is pushed through in accordance with what the O2 sensor is reading?

Yes closed loop means the AFR is determined by the Oxy sensor reading and the comp is updated and fluctuates the fueling around stoc 14.7:1. This mainly tends to happen when engine speed and load doesn't vary too much ie cruising down the highway

Dan

[31zook]

14.7:1 Im guessing is the fuel mixture ratio???

[JrZook]

Is the chemically correct air to fuel ratio for best burn.

[31zook]

ahh i see, thanks

[Brett]

for the cleanest burn, you don't want 14.7 when under load, you will have no power

best to aim under that except for idle

[LAY80N]

^^^^ More the point, you will damage the motor. 14.7:1 is the stoiciometric ratio, but running this ratio under load will cause huge cylinder temperatures , burin the fawk out of your valves, overheat your motor and most likley contribute to terminal detonation. Depending on the application a AFR of under 12.5:1 is much nicer on pump fuel and should make good power without causing issues. BUT this is very engine specific!!!!!!!

Below are the timing and boost maps from my Liberty's ECU (Im running a wrx STi RA spec ecu). This tune is pretty agressive. If i ran this on anything other than good 98RON and gave it a thrash then it would sound like a jar with ball bearings in it and probably go bang.


fuel map - 1995 JDM WRX STi RA



and heres the base timing map



and the timing advance



Layto....

[JrZook]

Far out am I reading the timing map right? 20-45degrees advance at 1200RPM!! Man that is aggressive!! Is the engine load on those maps set from min to max in relation to the numbers? I'm assuming so due to the decrease in AFR down the colunms. If so the timing map is kinda interesting, increasing advance for increasing load.

Dan

[31zook]

Thats insane... there is a stack i don't know still. Will be PM'n layto for sure...

I rang athol and he will pass the injected system on my lwb if i get a exemption letter from the RTA. Here are the questions i need to answer.

1: Why can't you continue to use existing forms of transport?
2: Please explain what the vehicle will be used for?
3: What is the reason you need an exemption?

If anyone wants to answer them i would be very greatful, as my answers so far are not being very helpful to my cause....

[Brett]

that doesn't sound right. you shouldn't need a exemption. you want it signed off and to be tested. you should only need to meet the emissions from the year the engine was made.

[31zook]

Because it changes all the emmission stuff, and is not a factory option it need to be engineered as far as i have been told...


Also ill let you know about the paint can you ask him just how much it would cost for my lwb to be painted inside and out, ill bring it to him in pieces on a flat bed truck

x2 Lwb's

Very interested!

[Brett]

your not engineering the injection system your engineeing it to meet emmissions for the year of your engine so you don't need a exemption. doesn't make sense to me.

i'll ask him when i see him next time i see him.
