Hyundai Alpha engine. But I can't really remember correctly because on some they had the mitsu engines and some had the Hyundai Alpha engines which came in N/A and turbo. Parts are very ex here. The MAF sensor is RM1200 and you can only get it from the dealer. ouch! I've asked almost all kedai potong, nobody has it.
I believe the turbo engine can push out a decent amount of HP. I think up to 200. Hmm...
