still in a sort of thinking and planning stage but i want to give this a go
at some point.
i used to own a r19 with the 1794 cc single point injected engine running on an ECU and producing 95bhp . mind you there was a standard CAT plus power steering on that car stealing some horses .
anyway ,i scrapped this car keeping the ECU,complete cylinder head,throttle body , engine wiring ,downpipe ,ignition coil .
now i have a r9 with the 1721cc engine running on a carb and a renix ignition computer producing 88bhp and i want to convert it to EFI on a single point injection basis for mostly reliability purposes . would not mind a bit of extra power and torque either .
the idea is to use the 1794 cc head on the 1721cc bottom end (both F type renault engines and as far as i can see the both heads will mate the block)
the only major difference between the 2 heads is the EFI one (1794cc) has knock and coolant temperature sensors which are plugged in to the engine wiring to inform the ECU .
on the other hand i will have some issues like an electric pump instead of the mechanical one run by the camshaft on the carbed engine . allready found an electric pump from a r5 gtt pushing 3bar which is plenty enough for the job . also it is an external pump that needs to be located just under the fuel tank which will save me swapping my fuel tank with an EFI one .
so far what do you guys think about this ??
ideas ,all recommendations welcome
