here are some pics of my 280zx at one of the drift days i went in

dont have the crank angle sensors, knock sensors, oxy sensor, or any others that a turbo engine would have that an NA one doesnt. does anyone know wat the extra pin in the N/A air flow meter is for? the plugs are the same, just the turbo AFM has one less pin.

yes i'm running an NA engine, decompressed, intercooled, with a locked mechanical advance. adjustable rising rate fuel pressure regulator and an apexi SAFC piggyback ecu for finer tuning. the turbo parts i have are injectors, and AFM. i have a turbo ecu but i dont have the sensors required to run the ecu, or the turbo wiring loom.

i'm trying to get my 280zx na to run with a turbo and am living in austrailia where 280zx turbo parts are very limited and hard to come by. i managed to get a set of injectors complete with rail and fuel pressure regulator, and also a turbo air flow meter. my question is, will the car run off the turbo air flow meter if i just hook it into the existing na plug and ecu? there is one extra pin on the NA air flow meter.. does anyone know what this pin does? is it just an earth or is it something that the NA computer will need to work properly? thanx in advance

started up my car and had a drive this weekend, it was going quite well. a few minor issues to be sorted out though. tomorrow i'll be installing the rising rate fuel pressure regulator (which is on a slightly higher ratio than 1:1. the efi guy recons it will do for my car, and it should reach the fuel pressures required) with the standard n/a setup it will run fine untill it gets into the boost. it misses and splutters a fair bit (but i've been keeping off the boost for obvious reasons) for some reason its blowing lots of smoke and fouling plugs really bad. i'm gonna take a good look at the efi system tomorrow to see if i can sus out any problems. it seems to be fueling up when i try to start it

i T'd it from the oil pressure switch next to the oil filter. just be carefull that the switch will clear the oil filter if u have to move it out further from the block. i'll ring up the EFI shop again and clarify what i'm after. might print off these pages and read them directly

just bought a rising rate fuel regulator rated at 0-15 psi of boost, that should do the job nicley. its comming in on tuesday. thanks again for the help everyone, much appreciated

i welded on a small peice of pipe to the side of the pan, then just ran a hose from the oil outlet to the pipe in the oil pan. well i'll probly start it on the weekend with a bit of luck. guess i'll wait and see how it runs and listen for any off noises will turbo injectors fit my settup? if they fit in i might upgrade in the future and up the boost a little. and they dont seem too expensive either

wow, thanx heaps for the walkthrough. that helps heaps.. i have a boost gauge, so if i hav to drive it i'll keep a close eye on that i might have located a digitech ecu soon, so that will work wonders thaks heaps for all the help guys

no, i havn'e started altering the ignition yet. to lock out the mechanical advance do i basically have to stop the springs from altering the timing through centrefugal forces and only use the vacume advance, which should just be a line goin into the distributer somewhere from the intake manifold? i'm not 100% sure, so i may be way off is an FMU a form of rising rate fuel pressure regulator? what would happen if i was to run the car without altering the mechanical advance or the FMU? would it just run rough or would the outcome be something more sinister

sorry, i should have said that i have dished pistons with a 40thou overbore and its intercooled. i think there may be a spacer, but i cant remember for sure. i bought the turbo and manifold as is. i've added a 3" dump pipe and that follows all the way through to the rear muffler. its an internal wastgate that i had tested to see when it would open and it opened at about 7 psi. everything is in the car and ready to go, i'm just putting the last couple of things together before its time to start it up i have sorted out the oil feed and return for the turbo. i used a T peice and added it onto the oil pressure switch. 280zxt parts are a VERY rare find in australia, which is why i'm having to use na parts. i could find a fuel pump and fuel pressure regulator from a z31 turbo. would these work? are 280zxt injectors a direct bolt in with the na engines and wiring loom?

is it possible to run a turboed n/a motor at about 7psi with out modifying anyhting else other than ignition timing? or will the cold start injector, afm fuel pressure regulator and pump NEED upgrading or modifying? its a standard n/a motor, f54 block n42 head. t3/t4 turbo, na injectors, na computer etc i want to start the motor this weekend, just wanting to know what to expect thanx
