Question for anybody who has done an RB conversion

[Ivan]

What did you do for a radiator?

custom built radiator? does the skyline one fit? did you get the z radiator core increased or just use the z one as it is?

Thanks

Hi Ivan,

you may have seen my RB26DETT conversion in my 240Z.

I used a Holden Statesman radiator which is a triple core unit. The radiator fits well between the rails, only requiring the radiator to have a few holes drilled for the bolts, and a small amount of metal to be trimmed on the radiator itself, not the zed body!

The other problem using the Statesman radiator is that the water return is on the wrong side of the engine block, so what I did was get a stainless pipe made to cross over the water to the correct side for a RB block (water in and out on the RHS of the engine on RBs)

I replaced the factory fans with twin 10” electric units, there are photos of my radiator and fan setup in the gallery section.
