turboing the tb4.2

[Trav]

howdy peoples, i have a gq ute with a tb4.2 in it its currently carby but i have the inlet plenium and injectors, dizzy oxygen sensor, i dont have the airflow sensor as the wreckers i bought it off wanted 700 bucks for it stuff that i said as when i rang them i wanted a quote on the whole efi kit so i could just bolt it on and i mean i wanted everything the loom computer, everything so 2000 bucks later no air flow meter. Im thinking now that i want to use comodore computer and stuff just make up a new loom has anyone else done this with out going to someone else that will charge you lots of $$$s. im not paying 700$s for a airflow meter considering its second hand, im turboing it at the same time as i have a turbo and manifold sitting in the shed i really would rather not to run a airflow meter just another thing to stuff up, any help would be good..

gday, im also turboing my carby patrol but mine has the 3.0 petrol, luckily for me i can use all VL and skyline gear, which is fairly cheep. Dont even consider using a factory airflow meter for that price, get hold of a microtech or Wolf they are that cheap now probly around the $700 mark. Actually i have an early motec for about $550 if ur interested. Anyway this way u can do away with the airflow meter free up the inlet tract, AFM's are tempremntal things anyway especially on a 4WD dust water and stufff.
I have all the wiring diagrams and clever stuff all drawn up if its any help, aslo if u use an aftermarket ecu find ur self some RX-7 non turbo injectors about $20 bucks each and will flow about 400hp (heaps). oh and turn down the plastic barb on the end in a lathe so they fit the standard fuel rail.

cheers

G,day I am also converting a tb42 carby to injection and turbo. Like you i was quoted stupid prices from a wreckers but ended up picking up a complete injected motor for $800 with computer and afm not that i will be using them. I agree with Brunsy the aftermarket ecu is the way to go.

Was talking to someone that works in a 4b shop that deals with turbo petrols. And the info I got was that the std Patrol ECU could not handle being turbo'd and you need to go after market. As the it dosent understand it needs to feed more fuel in when under boost.

yeah ok thanks for the info peoples i new that about the computer, i was gonna use the commodore v6 computer i really wanted to not use a airflow meter for that exact reason "mud and water" that computer sounds good, and the wireing diagrams now they are handy i would be grateful if i could get them off you.. let me no what you reckon on the computer im not up with prices on aftermarket comps, im not looking for outrageous power but i think with a moderate power increase will be more fun then standard petrol..
