I dont have a shroud. I live in Hawaii. Running 2 12 cheap ass ebay fans. I have seen other people run the same fans with no issues. What are your opinions. Should I buy a shroud for the cheap fans for 270 on the 420 FAL Fans directly wired up

Yes I have seen your write up Sli 85. We all know you have a bad ass write up. Kudos to your project looks and turned out great. I am not a fan of cutting up my radiator support but I also wish I had the air flow of a clutch fan... but as we all know s13 rb25det setup leaves your with little space for clutchfan

You really should run a shroud. You don't need super expensive fans as long as you have them wired to turn on and off at appropriate temps.

Thanks, but if you looked more closely you notice that I did not have to cut my upper core support to fit everything. If your not running a condenser then it def should not be an issue
