the 2nd best mod ever for a prelude.
Hoping things workout well with your R&D bud,I been away from the PC for a while so couldnt get to comment on some of the questions you raised,hope all works out looking forward to seeing the end result.

BB6 serviced, new LiquiMoly oil, TRS oil filter mod, Koyo racing radiator fitted, LiquiMoly coolant flush, Mishimoto silicon radiator hoses fitted, racing brake lines fitted along with the very best, Endless RF-650 brake fluid.

Stopping power and balance is now... phenomenal.

Combination of our hill climb stage 1 kit and this setup ensures great stopping power and precise pedal feel. In terms of cooling parts, radiator is doing its job, keeping things chilled very well. Next on the cards however is a racing thermostat to get the coolant mix flowing sooner.

Thanks for the comment Wayne, took the vehicle out for a late night burn yesterday and can say 160 - 0 doesn't take much effort (testing for race track and emergency braking).

One thing I did forget to mention is the new fan setup - two new TRS 12inch slim-line performance fans. (Not even listed in store yet)

... and they work bloody well

What part? End to end or the radiator? If radiator & pipes. Easy. If brake lines, also easy.
