Fits: 88-91 Prelude
(Coming soon. Currently in development.)
K-series swap kit for 3rd generation Preludes! Yes, people have been asking about it for years and it will finally arrive soon.
This kit is designed to give you the best possible ground clearance without requiring hood spacers or cutting a hole in the hood. However, cutting off part of the under hood support structure is required for valve cover clearance. Running a low profile oil cap and dipstick is also a necessity.
These are “swap brackets” not “swap mounts”. They bolt onto the engine and chassis and allow you to run a complete set of 4 Acura RSX Type-S M/T engine mounts. Like other Prelude Engineering LLC swap kits this allows you the option of running OE rubber mounts for the refined low vibration engine swap of your dreams. It's possible to use select aftermarket polyurethane mounts with this kit as well if you want more of a race feel.
A Prelude Engineering LLC K-series traction bar is required for this swap due to engine and radius rod clearance.
Please read through the install instructions below for more details about this kit.
