R31 Rb20Det

[swampratgriffin]

So I'm planing to drop a rb20det slivertop into my 1989 r31 silhouette and just wanting to know will i need a engineer certificate or since im stepping down in motor size all i should need is a blueslip. I live in N.S.W by the way

Non-turbo becomes turbo? Dreaming if you think they consider that to be a "downsize". You will have to comply with whatever they say you do, which at a minimum will mean R32 sized brakes. In SA you could get by with a properly written application and fronting for tech inspection with a completely roadworthy car and no need for an engineer to be involved - provided you make sure that the car will tick all the boxes that an engineer would require. In other states it is usually easier to involve an engineer, but I don't know about NSW in particular.

Yes you need engineer's certificate.

sell it and buy a r32 with a 20 in it. they're cheap enough now.
