No matter where you buy your Holley stuff, go to Holley's website first and verify that they are a Holley Authorized Dealer.

You guys also offering an intermediate harness like the Casper's one for xfi to use existing factory harness?

 

[sackracing]

Not at this time. An intermediate costs 300+ and doesn't solve some of the 30 year old factory harness problems.

Why do they call you "SACK"???

 

[sackracing]

It's an old work nickname, guy who started it was killed in a motorcycle accident. He was my apprentice for a couple of years. I kinda kept it in his honor after I left there.

So is this thread about installing a holley EFI system in a turbo buick?

 

[sackracing]

Yes

 

[lxmodguy]

So you completely remove the whole factory engine harness and replace it with this? Does it include a coil harness for holley or LS coils?

 

[sackracing]

Coil harness is extra, but it has the left and right bank pigtail on each side.

 

[toolguy874.1]

Does it use factory style injection plug and harness?

 

[sackracing]

It will use the factory ls injector and coil harness, not the buick

 

[toolguy874.1]

Ok thanks.

The wiring is plug and play and will completely replace the 30+ year old harness from the ECM to the engine sensors.
