Sorry to jump in as my first post and ask a question but im at a bit of a loss on who to ask! So cosworth owners seemed the best answer

Im building a williams clio turbo with a standalone (emerald) management (the first i know of to have a standalone)

Unfortunately being a standalone i need a high impedance injector... The injector i initally wanted to use were the green 803s, but these are low impedance!

Any advice for an injector similar to the green 803s with a high impedance??

Or even a good place to look?

Many thanks,
