Your intro music and slide show has become iconic! With great content following. One of the most simplest mods netting superior insurance to the cooling system using a one piece solid aluminum radiator. May I suggest after a few rips around maybe a week or so, check all hose clamps for tightness. Great bunch of friends too!

Greatly Appreciated !! and thanks for the advice will do! I noticed the next day it needed alittle extra coolant as well 👍🏻

Nice video mate. If your pushing 400whp which is a lot for a EJ25 long term. I highly recommend installing a thermostatic oil cooler from HKS or Mishimoto because the factory one is not efficient enough. Especially if your on track or your pushing your car hard HKS have done testing at Fuji Speedway Circuit with data to prove. It's just as important if not more important than a Radiator upgrade. Especially when it comes to the common Ringland failure these cars have when modified or tracked hard. hope this helps 👍
