The engine is still in peaces - plan is to finish it until end of August. I have a trackday scheduled in early september, so I'd like to finish it until then.
Head porting is finished, modified valve guides going in and hopefully also valve seat will be reground this week.
I'm still waiting on crank balancer, but as I haven't received rings yet, bottom end can't be assembled yet anyways.
The intake runners have also been enlarged and matched to the head (as you know, ports actually don't line up from factory)
This is the intake runner and most of the material removed.
Matched ports to intake:
The intake manifold itself will also need some attention - the plan currently is to cut and weld the aluminum intake from 155ts engine I have (FWD intake can't be used in a 75 without modifications as it is well above hood line and 164ts has plastic intake - so it can't be easily modified).
To see if motronic can handle the increased flow and bigger injectors, I've bought a wideband controller (SLC free from 14point7), which I plan to use with a logger of some kind, but as I don't have any experience with ECU tuning I'm trying to learn as much as I can at the moment.
