...Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it.
I built my LS powered 240SX using LOJ's swap kit. Stephen makes an excellent product and backs it up with excellent customer service... I will definitely come back to LOJ if I decide to do the swap in my 300ZX.
Incredible customer support... The designs they made are incredible and the care for how good a job is done is definetly one of their strong suits... [LOJ] has been a life saver by helping me finish this swap.
...I've been a Z fan since I was a kid, also a Nissan tech but that swap in a Z I love it, these guys get six thumbs up from me. And I only have two, I think
