The JDM B21a

Back in 1990 when Honda was producing the 90-91 SI engines (B21a1) they made a limited run of them for a rare JDM model prelude, it's called the "SI States" model. The SI States model came with the B21a. Supposedly they only made 3000-5000 of them which is why it's very rare.

They came with: A/C, P/S, optional leather interior, armrest (option), 4WS, ALB (ABS). They only came with auto trans which has a LSD, they also had a traction control system.
