87efi

New Member
hello out there.
Today my ordered topran 300065 ignition coil arrived. (ordered by comparison number)
But there's a big resistor(1.6ohms) added to the package and I'm not sure if I need to have this one mounted on the coil Vehicle that It was ordered for is a 87efi flapper thats original coil has no such resistor. Can someone give me some advice please?
Thanks in advance.

Welcome to LZ,

What is an "87efi flapper" ?
 
It's got the 'flapper' type airflow meter which uses a flap to measure airflow as opposed to the later 'hotwire' airflow meter which uses a heated wire.

I have no idea about the resistor.

Me neither. Resistors with a coil are something I only meet on really old Series that have an 8v coil. No idea why an 87 V8 would need one.
 
OK.thanks.did a lot of reading..and it's like turboman mentioned- an 87efi needs no ballasted coil. After some measurements following the Haynes book..etc..I ordered a new ngk 48339 coil that's made for operating at 12v.
Thanks a lot guys
