Aaron’s videos and DIY guides gave me the motivation and confidence to work on my car.
I replaced the oil pump and fixed the ignition of my 240Z with relative ease.
Thank you Aaron! Keep up the good work.
I found Aaron's videos to be an excellent detailed source. Great content across the channel to help any car enthusiast and not just Datsun owners make informed modifications to their setup.
The in tank fuel pump setup and installation tutorial by Aaron was the best option to future proof my build without breaking the bank. A true DIY install without use of specialized tools was a plus too!
