Frequently Asked Questions
-
Where can I purchase DIYHEMI.com products? Click here.
-
What makes/models do you support? Our products are designed to retrofit any 2003+ Gen III/IV Hemi engine into your vintage project. Late model vehicle swaps are not supported at this time.
-
Do you offer complete wiring harnesses? Not at this time. Our current wiring harnesses are our QuickHemi series. They require that you use the factory engine harness for your application. The QuickHemi simply allows the factory harness to work in standalone configuration.
-
Do you perform Hemi swaps in house? We do perform engine swaps for R&D purposes. The knowledge gained is shared with the GenIII swap community and new products are developed this way. We do not do routine installations at this time but will in the future.
-
What is the lowest cost GenIII swap engine to use? Mostly the 2003-2008 truck 5.7. They are very low cost and can run off a standard US based 2005 Dodge Ram ECM. These are the shoestring budget swaps that really pack punch with little upfront cost. Any Hemi is an excellent choice, prices may vary.
