Engine Building Service
You will be hard pressed to find a more complete engine building service than Modified Racing Inc offers. I have
built Motors for all applicaitons from drag and road race to daily beater. Experience, attention to
detail and technical knowledge is what sets me apart from your average engine builder.
The following is the most common forced induction engine build that I perform for my customers. This setup is best
suited to use up to 550whp. It is able to do 500whp reliably on an engine that is
designed for efficiency but at that point you should consider upgraded sleeves for added cylinder
wall strength and prevention of crevice errosion.
Modified Racing Inc, engine building service is $2,000.00
Standard machine work is Included in that fee. Additional machine work costs are listed in the
price breakdown. Minor shop supplies (RTV, copper spray, parts cleaner, etc...) are also included
in the price. Return shipping is not included. You will be responsible for all shipping charges.
