Rb20 Electrics To Fit Rb26

[silvio]

i just got a fairly bare r32 rb26 with just the block, head, harmonic balancer, intake and exhaust manifolds no electrics left on it and its been sitting a while and dunno how manny k's its done so its gonna need a rebuild but i've already got a rb20 in my silvia is there any way i could rebuild the rb26 and still use the rb20 wiring harness and electrics, i got a heltec E8 ecu setup for the rb20 and i guess that can be adjusted for the extra displacement , any help would be appreciated

ok so i got the engine rebuilt and putting it all together now so is it possible to get this 26 running with my 20 harness and programed haltec ecu

help me out lads i think it will work i just need some backup

From what i have seen and read the looms are completly different.

So no, you will ahve to make your own or get a rb26 one.

just get a new haltech loom and wire it in to the 26, it was easy to wire it in from a SR20 so the going from the rb20 should be a piece of piss.

ok so can i use the igniter and cam sensor from the rb20? and the harness cant be to much different even if i have to lengthen a few wires here and there

URAS what do u mean buy using the heltec loom cos this engine has no wiring harness at all all i got a rb20 harness to play with

Just use all the rb20 sensors, and it should fit up fine, the only problem i can see is the TPS depending on what you are going to use for an inlet manifold

i was thinkin that too but i'm hopeing the sensor will be similar even if i have to cut and solder the wires to fit if not iwas thinking of buying a greddy plenum or similar and puttin a 90mm throtle body on it

The haltech wont like the 6 throttles, unless you make up a little vacuum plenum

so how would i go about making one of these vaccume plenum thingies and how would I hookin it up????

[Adriano]

Its basically a small box with 6 hoses going to each of the runners, and then some others to go to the map sensor, FPR, boost gauge etc. It is designed to dampen out the intake pulses to prevent "confusing" the map sensor.
