Redtop Harness + Power FC with Blacktop Longblock?

[BiG MiKE86]

Stupid question... but can a S13 blacktop long block be used with redtop harness and power fc for redtop? will everything plug in? work? I already have the fat O2 wired in.

Well I mean... it does seem like a stupid question.

How is that any different from asking 'Just wondering if my PowerFC for s13 redtop will work with my s14 blacktop with s14 wiring harness etc.

I'm sure there is a reason as to WHY they have different versions of the PFC for each engine.

Blacktop S13 engine vs Redtop S13 engine:Different 02 sensor, and some wiring changes afaik.

What SR long block you use dosent matter,
All the S13 long blocks are the same the only exception is the Kouki "Type X" which has slightly more aggressive cams. All the sensors are the same except the O2 Sesnor
So whatever ECU you have use that wireharness and use with the O2 sensor

You will be fine as long as all your sensors match your wiring harness. EX: I see kouki s14 sr's in zenki s14's ALL the time here, and the cars still have the zenki ecu, so it has zenki wiring/sensors and it all works the same. As long as the power fc is for the correct wiring/ecu your fine. Ex, you can't use a s14 zenki power fc on a s14 kouki set-up.
