The car has been going great and has definitely been worth it for me, however, I only went down this route because I had the correct turbo and weber manifolds to make it a suck through set up, and I wanted to keep the mods period.
I have been contemplating about going with an EFI setup but with the additional mods like intercoolers, injectors, ECU's, fuel regulators, etc, then yes I would not bother with the crossflow and go with something more modern like the Zetec.
Overall but I have been more than happy with this setup, it was pretty straight forward to achieve, the difference in the performance is incredible and there is still the potential for some more improvement. Sorry, not really up with posting on youtube.
