Our Customers

Top quality work from JHH Racing! - Built my 4G63 2.2 Stroker Great customer service, answered my million questions in fine detail..always kept me up to date on the progress from start to finish. Would highly recommend! very professional

Derek Cowley

JHH Built an unbreakable 4G63 for my RVR which was the perfect combination to suit my needs and budget. Outside of the obvious, the attention to detail in the build and the experience and information provided in consultation prior to the build led me to not only spend smarter whilst providing me with a saving grace from making an ill-informed decision fuelled by misinformation I had gathered online. Would recommend EVERY time.

Matt Leasegang

Will and his team at JHH Racing did an outstanding job on my AEB 1.8t motor. The attention to detail and final product speak for themselves. Would recommend highly to any one. Great communication and advise through out the whole build process.
