Injectors 3rzfe?

[Tweak]

Iam doing a fair bit of work to my 3rzfe engine, forged bottom end, gt35 turbo, motec m400 ,
trd lsd, LC racing clutch, LC racing cylinder head street package internals
Plan is to run around 25 psi ,maybe more
But come to the injectors and fuel delivery iam stumped mainly concerned for the injectors and also the fule pump
Help me out

[brett_celicacoupe]

what are you actually trying to achieve?

A bullet proof 3rzfe in a stock standard hilux 03 single cab,
Dont wanna know about how old m8 is running " stock bottom end with 20psi" crap cos iam not interested yes its probly true but not what iam after.
Ive read thatr 600cc injectors or even 750cc injectors would suit but id need to make spacers or somthing to the orig rail. may even just make up a custom rail if i have to

[brett_celicacoupe]

ill be making a custom rail from extrude when i get around to it.

at this stage im looking at using 1000cc Rochester injectors.

youll have problem finding injectors with a 11mm feed end

does that help?

[Billzilla]

A good rule-of-thumb is 5cc per hp.
So if you want to make (say) 700hp then you need a total of 875cc per injector, but add 20% to allow for a buffer to avoid the injector maxing out.

found a good site for 14mm injectors. they have shit lods and diff brands

second question whats the difference between low independence and hight dependence

[Glenno52]

Old thread but.....Does anyone know the flow rate for a standard 3rzfe injector.
Or, what HP would standard injectors expect to be maxxed out at?

When I was originally going to turbo my 3rz-fe 4x4 I picked up some 440cc turbo-II RX7 injectors which were plugnplay. I was only looking for around 300hp (max of 350hp).

Yeah...was thinking of going along that path, but wasn't sure of the year and model RX7 that had suitable injectors to fit straight into the 3rz.
Still having issues with lack of performance from the TRD Supercharger fitted and thought injectors might be the next move.
Otherwise, any info from anyone who has fitted a TRD Supercharger kit to a 3rz-fe would be greatly appreciated. There's either not many about, or nobody wants to admit they've got one!

US 4WD forums and the like might be worth a look, 3RZ's were used in 1st gen tacomas and theres a pretty big mod scene for those

Had no luck there...even posted on one of the US forums!

I'd be happy to talk to anyone who has fitted a supercharger or supercharger kit to an engine that didn't come standard with it, and tell me they are completely satisfied with the performance for the $$$ they've spent!

[Omegaman]

from what i found.
3rzfe was in 96-98 4runner-Jecs-OEM 23209-79095 or nippondeso no.23250 75050
also a tacoma 95-98 and t100 94-94 OME 23209-79075 or nippondenso no.23250 75030

the end result is top feed, high imp 13.7ohm 298cc (see Pic) if the same.
So later model RX7s
hope that helps.
