Rb30 Holdern Into A Skyline

[mr30Turbo]

Hey guys, i just brought my first car today, its a 1987 TI and it has a blown motor. I found a motor out of a vl and i was wondering if it will just slip straight in and run with the skyline ecu or will i be better changing the ecu's? and will there be any other problems ill run into? thanks:)

I don't know what a series 2TI is but if its a Skyline you will need to find a twin cam head etc and do a proper RB30 conversion as per the section above.

Its a 1987 TI, so what do you mean with the head?

Appears to be a straight RB30E swap from a VL to an R31... so to restate the OP's question, will a VL RB30E be compatible with enging mounts, loom and ECU from an R31 RB30E?

The above ^^ is only relevant to twin cam rb30 builds.

Yes, the VL rb30 will work in an R31.

You will have to change the harmonic balancer depending on if you want to run R31 or VL accessories.

Easier to use your crank angle sensor and distributor your ECU was already using, you cannot interchange CASs (vl - hitachi, r31 - mitsubishi) only the distributor as a whole. Use the same alternator.

yeah so ill run the r31 accessories, so with the ECU i cant use the skyline one? do i have to put vl one in?

[JezR31]

R31 ECU is fine. Just change the balancer for the R31 accessories. Done

[mr30Turbo]

yep sweet guys thanks for the help!

I've had a VL and an R31, they ran different ecu's.

That's not to say it won't run, just informing you that good old GM wasn't satisfied with the Rb30 as she came, they had to tinker.

Different fan and fan clutch too, another weird thing to change.

Yep sounds like there isn't too much work involved, my uncle specializes in rb30's so he will be able to help me out
