Rb20 Silvertop Conversion Into A Hr31 Passage Question?

[HR31-PASSAGE]

hey guys

just a question if i replace my rb20 redtop with a rb20 silvertop or even might be thinking of a rb25 (engine, gear box, ecu & loom) will i have to get the engine tuned to suit my hr31 passage if it comes straight out of a running r32? or will it still run fine?

also are there any mods i should know about to do the conversion?

cheers for the help guys

use the loom and standard ECU of the motor you put in.... and put an RB25 in there, Phantom32 is selling one out of his R32 for ONLY 1500... i have seen people pay that much for RB20's!

can i reuse my original loom thats in the car already? for either a rb20 or rb25??? or are they both different?

cheers

repost of an FI thread.

For silvertop its not that much of a drama, R31 Skyline Club has most of the answers about both conversions actually, because thats where most HR owners hang out
