I hava 13B rotary ina 3rd gen, single turbo conversion, street ported, brand new rebuild. Also with block off kit installed. I was lookin for some advice as to finding the vacuum leak. It will start the warm up sequence and idle at like 2k or w/e and hold there, but once it warms up and drops like its suppose to, then the idle goes up and down. Between like 1k and 2k. Sometimes it doesnt fluctuate that much. But anyways any help is appreciated.

you can try to spray brake cleaner or carb cleaner on parts of the motor that you suspect to have the leak and if there is a leak, the car will stumble a little bit.
make sure all of the manifold bolts and accessories attatched to the manifold are bolted tight
