...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.

David S.

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.

Kyle A.

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.
