Hi all , my 1986 Australian spec L RX Turbo finally got its new engine fitted a couple of weeks back and I'm going to need larger injectors for it .

 

Just to fill the gaps my EA82T has a TB flange modified Spider inlet manifold to mount the std 3 ECU type TB and TPS . CR is now 8.1 , heads are ported and cams are late MPFI NA . Lots out of the flywheel as well . Is this the only 3 plug Spider EA82T in existence ?

 

I need to know if these early 3 plug EA82T's have low or high impedance injectors and if the flow rate is the same as the later 4 plug systems squirters ie ~ 225cc min .

 

I understand that the 280ZX Turbo brown top injector is a bit larger at ~ 255-260cc but will they work in electrically the early 3 plug system ?

 

Also if not is it possible to use the resistor pack from later EA82T's to fix the impedance issue ?

this is so far over my head I just had to post this to say this was so far over my head

 

doing some serious cutting edge retro-research down under, please keep us posted with some details and maybe pics of this car, it sounds very interesting

From the outside it just looks like any other std white Aust spec 86 RX Turbo Sedan , under the lid the only obvious differences are the spider intake system and a Vortex (XT4) pitch stopper and transmission mount .

Spare wheel doesn't fit any more and lives in the boot (trunk) .

 

Can anyone confirm that early (85/86) 3 ECU plug EA82T's use high impedance injectors ? I suspect this because they don't seem to have any form of injector dropping resistor .

Early and late Injectors are identical from everything I've ever seen.

 

I have interchanged them without any detrimental effects.

Interesting , had a friend of mine test an Aus spec spider XT4 turbo injector and it measured ~ 2.8-2.9 ohm . Must ask him to test one of my early ones to confirm .

 

Cheers A .

Looked through every year L series and XT FSMs and the spec for ALL MPFI engine injectors is between 2-3 ohms

There all in that range. It is the XT6 that uses the 14.7 ohm injectors.

 

May want to source some European XT turbo injectors. Don't know what they flow but do know different from those used in the North American version. Thinking they have brown tops. Euro spec XT turbo produced something like 135 hp.
