resistor packs

[FLY-SKY]

hey does anyone know where i can get resistor packs made up so i can run low impendence injectors for my rb20??

it sounds like you are in the same boat as me

some old cars have them eg honda CRX

or you can wire a 8.5 ohms in series per injector, this should increase the resistance to around 11ohms and prevent :flamed: the ecu

I've yet to try to any of these methods as my friend is sending me a box so I don't know which brand of resistor to use.....may be other guru will help.

you can wire in a GTR resistor pack, which is what i got done to fit 550cc low impedence injectors to my RB20, running AP Eng PFC. available new from Nissan, or try your luck at wreckers.

how much is it new mist?

You could also try the packs (called "dropping resistors") that were used on any of the early (R30) Skylines. Should be available from wreckers at a relatively small price.

I have been told that you can use one large resistor on the common ground line rather than 6 individual ones. This would save on wiring and allow you to use a physically larger (higher power disipation) resistor.

Do not use a wire wound resistor. :Bang:

hey mist, where can i get them from? how much did u get your one for?

[V8eta]

I got my resistors to run the 450cc 4g63 injectors from Link Electrosystems in NZ, was about 150bucks but the aussie agent for link should be able to get them.

Putting a resistor in series with an injector will lower the voltage across the injector. If the injector drive circuitry hasn't been designed WITH THIS IN MIND as opposed to other systems, i.e GTR, would it not upset the operating characteristics of the injector?

150 bucks

I can get some resistor from Jaycar for less than 5 bucks

I had some made and all it was was six ballast resistors. I'll get the resistances for you tommorow cause I just finished working on my car tonight and can't be bothered going back outside.

i looked at the resistors Jaycar had - not designed for use in a hot engine bay mate... decided to go with the GTR resistor pack. BEL Garage sourced it and wired it up to the low-impedence injectors. can't remember how much, but i got a 2nd hand one. lucky it works.. personally if i'd known it's only $150, I would've bought new.

I have a Nissan 6cyl injector resistor pack....not sure what it's off, but if someone can tell me what the values of the GTR resistor pack are I can measure it to see if it will do the job. If so you can have that....

could you also let us know the brand of the resistor?

it looks like my parcel will FTA have to dig out my year 12 electronics books now :wassup:

[FLY-SKY]

so where specifically in sydney can i go to get a resistor pack for gtr injectors in my rb20?

[ed]

Try Justjap, or if you want new, perhaps Landers Nissan?

[Rowdyr32]

I don't know the brand of the resistors but I'll measure the resistance tonight

[Rowdyr32]

I think the resistors are 7ohm 10 watt wire wound ceramic resistors (I know the resisance is 7ohms I don't know if they are 10 or 17 watt resistors) from jaycar about $1.50 each and you need 6 of them. I'll find out tomorrow as the $100 pack I got from direct imports a few resistors died yesterday, I believe mainly due to poor construction as they were glued together and the ends covered with some sort of silicon and water may have got into the resistors ( I don't really know why they failed, all I know is they were wired up properly and it was running fine and now it isn't). A little metal box only costs a couple bucks and might be worth a go but the resistors may ge to hot.
