K Motor Fuel Injection

[Zoidburg]

Hi everyone,

 

I'm currently rebuilding a 5K and have a standard twin carb set up, but think fuel injection would give better performance. Does anybody know where I can find an EFI set up for it?

 

Thanks very much.

Right here... The answers you seek...

or here... D'OH!

 

That'll give you an idea of where to start looking.

you could possibly build your own inlet and efi system.

www.efihardware.com

[greenmac80]

on that website you can even get a k motor manifold. dcoe throttle bodies. ecu.. the works.. expensive but could work out to be far superior to

standard 4ke injection.

Thanks guy's.

 

I do know how to work the search function, and have read all the articles before. Guess I just overlooked building my own EFI system.

 

Reckon I'll go to the EFI Hardware site and take it from there.

 

Cheers :lolcry:

If you can weld and good with metal fabrication you could make your own system, get valves and stuff from a scrap yard. Am thinking of doing it myself, with my own ecu and stuff. Just have to wait for the programming part of my degree.

Talking about custom stuff and welding and all that crap.

Been thinking of modifying an aisan "k" carb into something like this

Injected carbies

Either that or a set of quads or twins from a motorbike.

And then its http://www.tweakit.net/shop/product_info.php?products_id=231 and weld four short sections of pipe to these http://www.tweakit.net/shop/product_info.p...products_id=138 for the motorbike throttlebodies

Bugger the Aisin modification, get a throttle body from an EA falcon if you want bolt on injection. They use the Weber bolt pattern so your adapters will work too.

And then you need an ecu that's intended for the capacity of the motor, i think toyota starlet's are a small enough motor, thats the easiest and cheapest way.

yeah but it will never run properly as its not designed to run on a k motor.

 

just buy a megasquirt!

 

400 bucks for an ecu that has the same features as an ecu in the $1500+ price bracket.

 

be prepared to read, alot.

Hmmm...didn't think you could get them that cheap. Even this if you know how to solder:

unfortunately i can't get to those ebay links from work...

 

http://www.diyautotune.com/catalog/megasqu...-kits-c-30.html

 

but these guys are pretty decent prices

 

253US for the kit (277AUD)

 

or

 

411US for one that is already assembled. (450AUD)

[jono1986]

Plus postage, which on the ebay ones are $32....

 

Damn I wish I saw this kit at the start of the year.

[ke70dave]

and while your there pick up a wideband for $200

 

http://www.diyautotune.com/catalog/innovat...-3769-p-41.html

 

and either find a laptop with a serial port, or get one of those serial-usb converters off ebay.

 

and your set!

 

it does turn into an expensive procedure though, but you are getting pretty good stuff.

 

~280 MS2, ~230 wideband, figure something out for the dizzy (unsure if the electronic k motor dizzy will work), youll need a few sensors (air temp, water temp). figure out what to do about a TPS. so not much change from say 700AUD.

 

then whatever you need to get a k motor EFI intake manifold (either make one, or buy an expensive OEM one that fits).

 

worth it on a stock 5k? i say hell no:P

Does anyone know how Triumph 2.5Pi injectors worked?

 

They were a simple mechanical system.
