or perhaps

or even

the secrecy and intrigue are killing me (taps hand on lap...) NOT !

IB 4G63 SOHC, or 4G93 SOHC

I thought there were mrsbitchy motors that were in that family and were 16V but SOHC?

There are !

It doesn't really matter what exact Head it is anyway.........

Does anyone know the acceptable minimum Head Flow velocity ? I.e. for when practically hogging out the Ports.....

[takai]

All depends on what RPM you want to optimally run at, the cams you are running, the size of valves, compression ratio, capacity..... you cant just pick a number out of the air.

Ok then.....

Inlet Port Diameter: 38mm (Doesn't mean choke diameter......// Haven't dissembled it to check)
Inlet Valve Diameter: 44mm (Can go 1-2mm Oversize...)

Exhaust Port Diameter 38mm
Exhaust Valve Diameter: 38mm (Will go 2mm Oversize, from previous experience here...)

Static CR will be 9.5 or 10.5:1 with displacement 2.2L or 2.4L respectfully.

4000-7000 RPM

Cam duration and lift really depends on Flow no's data more then Flow no's depending on cams.....

The new trend of porting heads seams to be actually filling on the port
