To fit the newer type injectors into an older type car do I just need a newer type fuel rail or is there anything else required.

I believe the newer type injectors have oval shaped connectors where as the older type have square connectors ...so you might have to change the injector connectors. Not sure you need a new fuel rail though, but I´m sure someone will be along soon to clear that one up.

You are correct. An adaptor kit will be req'd OR you need to change to the newer fuel rail.

And also change the injector connectors in either case.

 

For example....

When I upgrade my injectors, I shall just go for the Nismo 555's. Straight fit and same 90-94TT injector connectors. Costs more, but easier + proven.

Can anyone confirm if these are any good and fit

Don't do it. I had lots of problems with venom 550cc injectors including 1 sticking open when first installed from new and causing a hydraulic lock, another went completely dead, took me a long time and a lot of trouble to get replacements, I ended up buying an extra injector as the returns and warranty procedure took so long and cost me cash the first time. I was never confident that they were working correctly even when there was no obvious problem. It simply isn't worth the additional time trouble to use anything cheaper than Nismos.

As I understand it they are remanufactured from drilled out standard injector cores.
