Forward Facing Plenium Questions ~ Coolant Lines

[RB260Z]

OK so im doing a motor (RB30e+t) and turbo conversion into a Datsun Z, motor is in but im going to run a forward facing intake plenium. What i want to know is do i have to run all the coolant lines in and around the plenium? or can i just leave them off? IMHO it looks messy and i know they used to run them on the Z's but everyone disconnected em. Do they have to stay?

cheers

If you're running a 2 valve RB30, sounds like a Rajab style cast manifold? If so there would be quite a few VL boys with experience in this area.

Most experiences here seem concentrated on RB20/25/26 DET / TT

If you're looking to delete some coolant/heater lines around the manifold, probably ask yourself what you want to achieve, and you'll probably ge the answer whether to delete or retain. Colder climates and whether you can live with an engine that takes a bit longer to get to operating temps should be a part of the equation.

I'd be sure there are good answers at boostcruisin.com
