Are these headers stock?

I’ve never personally seen a set. But back in the day Edelbrock made headers for these trucks that had the Y go under the transmission. Not sure if they were Cali legal. But looking under the truck you’d be able to tell if they’re them or not.

plus. 95 with a supercharger? The EO for the blower is only 97+ I thought? Unless that trucks running a 97+ ecu. (95-96 ecus did not work with the blower)

 

Only photo I know of them. From gadgets site about his 4runner. Only person I’ve seen that’s ran them WAY back in the day

 

I’m hoping the guy who painted those valve covers and installed the sc knew it was 97+ and installed one - who’s tried to install one on an older one without finding out beforehand and seeing what happened… for science? Lotsa predetonation…?

 

Yeah it isn’t those if the pic is accurate and they kept it the same throughout their production. Look at the passenger side how cyl 1’s primary goes under the 3/5 collector.

This is exact opposite of that.



Might still be worth taking more pics.

 

eBay Australia sells “wildcat” headers for the 3.4. Google it up and it might be it. I’ve seen a post on 4Runner forums where a US guy bought a set and they cleared the steering shaft etc. PO might have done the same.

the only reason I’d hesitate doing this is you’re moving the AFR sensor further back and in a different position. I would assume that would mess with what the ECU expects to see.
