EFI Hemi Chamber Cylinder Head
 

Hello

As written in another thread I overhaul my Caterham / CVH Turbo engine. I have already converted the Inlet from MFI to EFI. The plan was to buy an EFI Stage 3 cylinder head from Bruton Power. Unfortunately Burton Power does not have any more in stock and they need an exchange unit.
The problem is Burton can't convert the head from MFI to EFI, so I'm looking for an EFI head.

But it is very difficult to get an overview. My current head is an MFI hemi chamber 88SM6090. As I've read there are no significant differences between turbo and non turbo heads.

I've read that the 89SM6090 is an EFi hemi head. But I've seen a lean brun at this number, so I'm insecure. Furthermore, it is very difficult to get one.

Maybe I'm lucky and someone in the forum can sell me one :-)

I would be very grateful for tips which others would fit.

For example, what is the difference between the 89SM6090 and this one here on ebay:

I'm a bit stupid :-)
The best solution would be to buy an MFI - EFI adapter plate.

Or do you disagree?

Is it a Ford cvh efi inlet manifold you have used?
Ferriday engineering make a top quality adapter plate to attach the ford cvh inlet manifold to a MFI head.


CVH head on ebay

Thanks for your answer.

This is my modified cvh efi inlet manifold:

Is there any disadvantage to use the MFI head with adapter plate instead of an EFI head?
