Southern Performance Systems

Purchased complete turnkey engine and waited over a year for a response from the owner, finally received complete turnkey engine and transmission both of which failed upon startup only to be blamed by southern performance for the failures sent everything to legitimate builder and was told used and junk parts were installed and had to pay to have another engine and transmission built. Beware of this group

Sold a bunch of wrong parts and will not return calls or refund any money for them. Just wanted to run up a high sales receipt. Worst service ever. Do not use this company

Called & got an answer so I was surprised based on other reviews. However, the guy who answered (parts guy) couldn't provide me w/ a quote even though the website ask for you to call. Then after several calls, exchanging contact info, i never received the quote. I called back several times & got in contact w/ the same guy who once again never got back. So either they are scammers or they need to fire their office staff SMH. Looks like my business will end up w/ Autotrend EFI which is a bit of a bummer b/c I really liked the look of SPS LS Stack Induction set-up.

if I could have given a negative 1 i would have. John Tucker the owner told me they would be working on my car the following week after I dropped it off to them. it needed work done to the engine a 2015 camero since their website said they specialized in LS engines. after about 2 weeks I started calling them to check. no answer. left messages. no return call. granted i live 100 miles away. there were occasions I called 30 times still no answer .I picked up my car and took elsewhere. horrible customer service. no communication. I do not recommend them. for anyone. they treat you as though you are unimportant

Ordered a ls swap for a 64 vette and literally everything had to be reordered cuz these people have no earthly idea what they are doing. Called bout engine swap mounts they sent that pushed the engine and trans 2 inches forward months ago. Was told they were sending adapter plates(even though they said they never had that problem) and never got them. Would never consider even ordering a sticker from them
