Excelsior Motorsports

I just took my C7 Z06 in for an oil change and had another wonderful experience at Excelsior Motorsports! On earlier visits, I had my vehicle aligned and all fluids changed out. Please note they have moved to a much larger facility and are now located in Oceanside. It was great to see Kushan (owner) again and checkout the new shop! This establishment is the best for your Corvette racing or daily driving maintenance and repair needs. Kushan and his staff are highly trained and experience on Corvettes! I highly recommend Excelsior Motorsports!!! They are super detailed, super high quality, and great value!!!

Excelsior Motorsports is very knowledgeable with the Corvette platform, they have done all the work on my 600 Whp supercharged C6 Corvette. Kushan is the best tuner in the business for GM motors, this shop has been my car doctor for three years lol I actually sold the car three weeks ago and they took me in with one hour notice to do a quick oil change and belt replacement before I delivered the car to the new owner. As you can tell by the reviews his shop has great ratings. Thanks again guys. See you on the next one.

I brought my C6 Z06 to Excelsior for head repair/porting, cam, long tube headers, etc., and my car is COMPLETELY transformed. I originally reached out to Kushan with just a general idea of what I wanted to do, and he delivered beyond my expectations. He is so passionate about his work which made getting updates along the way very fun. I will be going back for all of my servicing needs, and I’m grateful I picked his shop for the work!

Extremely knowledgeable on LS engines, ECU installation, and tuning. I brought my LS3 swapped 71’ Camaro to Excelsior and it was running pretty rough. They made some excellent recommendations, installed a new Holley Terminator X Max ECU, new catch can system and tuned it perfectly. It ran and drove really well. Fair pricing, timely service, excellent communication and customer service. Best of all, they know their stuff. Go to Excelsior for anything LS!

In my eyes the ONLY shop you should ever take your LSX car too in the SoCal area for performance modification or large jobs. Bar non the best work a shop can do for you with prices that are worth the work. Kushan and his techs know what they are doing and will not leave you disappointed. Picked up roughly 55 horsepower from basic CA legal carb compliant modifications due to their tuning expertise and high end equipment and won’t have to deal with the strict laws in the area 😁
