Kwinana Performance

The car doctors! Kwinana performance worked some magic on my car, helped me out with fuel and electrical problems when many other mechanics couldn’t.10/10 would recommend, always super friendly and genuine. When I’m in need again I’ll be coming straight back!

They replaced turbo on my triton no problem they called to let me know car is ready job is complete happy with price pick up car next day they want an xtra $500 they replaced manifold gasket without calling texting email to ask me first not happy I will never go back there I emailed them to let them know that they've lost a customer no reply not really surprised

They're pretty good and it's so difficult to find an honest mechanic in Rockingham - these guys have saved us a few times.

Took the car in to get new bushings installed + ball joints, obviously for the health of the car but mainly to stop the squeaking it caused. They also told me that it was leaking oil from the headgasket but I had never seen oil drip from under the car before so I thought that was odd. 2 weeks pass and $2800 later I get the car back. I was told that some cylinders weren't firing because my coils were broken but because I didn't say anything about it before, I probably wont mind, however if I wanted the engine to run correctly, they would charge $900 for 6 coil packs which I could do for $150. I started the car and I was angry to say the least. Out of 6 cylinders, it seemed as if only 2-3 were firing correctly. Took it back to them and they found out" that the engine was put back together wrong and that the firing order was incorrect (so I guess my coils are fine but obviously they didn't want to tell me that). They didn't charge me for fixing their own mistake which was surprising but if I actually said they could fix it

They fixed my harmonic balancer and breaks, while being very vocal and great at communication. They didn't charge me and arm and a leg and were very reliable. I would highly recommend

Had a 3.9 truetrac diff installed and a trans service. Work was done in a day. The boys are a friendly bunch and the work done was good. The diff really woke my car up. Keep up the good work and see ya when I get my cam and stall.Edit - 6 months later, got cam kit, lifters etc done...404hp...very happy

Great service on budget and on time definitely would recommend to friends and family.

Great people and great workmanship got a vcm13 cam package and tune they will not disappoint

My new battery was stolen and lied about my warranty.

They know there stuff mechanical. My vy sv8 was popping farting and coughing.Took it to them when I got it back it was tuned to perfection . I didn't know the old v8 had so much power . I highly recommend them . Thank you Maurice and staff .
