Description

As used on the Stage 1 turbo kits for the NB, this simple wheel replaces the stock trigger wheel on the crank nose. Unlike the stock piece, it leaves a bit of room for adjustability. The ignition can be retarded by up to 8 degrees or advanced by 4 degrees.

Adjustment consists of simply loosening four bolts on the crank and rotating the wheel. An indicator shows you just how much you're retarded or advanced compared to stock.

Great design, good fit, good power

The power comes on sooner at lower rpm, and pulls harder at higher rpm. On an old, 240k mile engine, this mod really woke the car up. A definite must-do for any naturally aspirated Miata, even if you're not a power hog. For the price and ease of install, it's hard to beat.

Little tight over the crank, nothing a little sandpaper didn't fix.

Very nice part, little powder coat inside the ID of the crankshaft hole. Some 180 sandpaper and slide right on. Car seems to have better idle, and just got its first tank of 93 octane fuel.

Yeah, these are tight over the crank to ensure a perfect fit. Sometimes that means a little bit of sanding to get that perfect fit.

Just works.

Order. Came in fast and works as should. I installed it in about 30 mins with no issues. Went right on. I let.the car warm up. Set the timing and boom. Better feel and response. I would recommend.

Simply works

Installed the adjustable timing wheel on my NB, only after replacing a failed, melted knock sensor. The sensor improved acceleration, and the later installation of the timing wheel at full advance instantly smoothed out the idle and further improved performance. Unlike reviews of timing wheels sold in the past, mine was a perfect fit without need to enlarge center hole or debur. Did not know until after removal of original wheel that it had a bit of wobble to it. New wheel is perfectly true.
