I just bought a car that has a RB Concepts C5 engine. I am finding it hard to find much information about the engine. I have seen threads stating that it is an onroad engine. The head looks offroad..ish. Dunno. Help.

Also looking for a backplate for the engine. The C6 backplate does not fit. Another Help.

Thanks!

Is this the one on the new IGT you just got? Have you fired it up yet? Curious if you are liking it.

A C5 with an offroad head. If it does have a 7 poort sleeve it can be a C5B(B)

If it does have a 3 port sleeve and a 13mm crankshaft (I believe) it can also be a CS , that was some kind of a low budhget engine by then a model under the S5.

Hi Zootcapri, I had the offroad C5 for several years, one of the best (if not THE best) engine I've ever had. It was the original, not BB or anything like that, see:



Just bought this one for my RRR, Rody tuned V12:



(Pipe is going to change for a V -type)

Mika.... That is the exact engine.

Roelof... not sure on the # of ports. Will look. Mika's top photo is the engine.

qjmcrae... this is the engine that came with the used GT I bought. Haven't been able to run it. Took some time just to clean it up.

Any ideas on sourcing a backplate? I don't want to put the pullstart back on.

V12 rody tuned... what a rocket!!! Gotta love RRR & RB V12
