If you are contemplating building a system yourself we strongly recommend
purchasing their DIY guide which contains a wealth of vital information.

System Specifications (tentative):
New components: fuel pump, filter & mountings / distributor pickup, ignition module, cap & rotor / coolant temp sensor / ignition coil / oxygen sensor / TPS
Used/Reconditioned components: wiring harness / ECM / TBI / MAP sensor / intake manifold
We are working on developing a system to enable conversion of a Range Rover intake setup as shown below to a MAP based system. Perhaps the greatest difficulty in building a retrofit GM port fuel injection system is the need to fabricate fuel rails and a throttle body. However, when purchasing used Range Rover engines for TR8 conversions, one quite often gets all those items as shown in the photo, thus all that (in theory) remains to be done is to add a MAP sensor (just needs a vacuum port) and an air cleaner! Even the stepper motor (IAC) appears identical to the GM version! Stay tuned for details!
