Wow nice build man, I must say that it surely looks like my build!
Looky ass that i for once was, i got my hand on a BTCC engine that comes from a primera during the late 90s in UK.
Anyway, the CAS is the same problem for me, and I looked at the mazworx cam sensor, but as it was no images of anyone using it (as I could find) I assumed it ti be mounted trough the ricer cover or something, and that is a non go for me. The BTCC rocer covers are of magnezium and they came in very limited numbers so I won't put a hole into it haha.
Perfect setup mate, Surely hope to see this build running, and I require som dyno/mapping video of high rpm
bet that beast is pushing out 600 rwhp.
Mine is built for 1100, hoping to have the car finished april-may, but might turn the key in January
Keep it up!
