We can do any swap you need. We're currently doing an RB26 swapped S13 but unless you've got a lot of money to spend I wouldn't recommend it. RB's are great for power but unless you've got serious HP goals and a large wallet its not the best choice. For roughly the same money you can have an SR putting close to the same power. Give me a call to discuss what options you want to go with and I can give you a more accurate price quote.
