I do remember a mini van that got everything under the bonnet. It can be done with the original subframe. The 16v mini forum is useful. I considered this option first. The reason I didn't go for it is the class rules change in hillclimbing, (my chosen feild of comp), in that if I change the block, I ...

Hi, the only machining that needed doing (for the head), was cutting down the cams off the pinto engine, decking the block (after filling the holes with threaded cast iron, angle grinding the plugs off, very carefully and moving the water passages with a dremel), the same as a normal block skim, Â ...

How the hell have you got the 16v head on the a-series block? Why have
you done that rather than going to a 7 or 8-port conversion or for that
matter to drop a K-series or honda engine in.

Hey CNG1, not having a go, and congratulations on getting it to work!

The BMW 16v head conversion has been done many times. Here is an overview of the 8V head conversion, the 16v head is easier to do due to valve positioning/size.

It is indicative of running out of time to inject discrete pulses directly into the port and charge robbing. This is why the wet manifold approach works and the port injection does not.

Just like the stock VW flat 4 air cooled engine, restricted by the tiny carb - this staggers up to about 4k as ...

No power above 4000 rpm is a classic symptom of charge robbing, any EGT data or oxygen sensor data? A stock mini cam will run to 7k on the A+. The issue is that you run out of injection window at around 4k. What is the duty cycle of the injectors at 4k?

So how are the projects going? Any updates. Going to try the single TB dual injector wet manifold route. Are there any starter maps for this set up on the a series engine? Thanks
