Fast Facts:
- A design characteristic that stands out on 3rd gen Preludes is the exceptionally low hood line. This was achieved by tilting the engine back 18 degrees, allowing the hood to sit 1.2″ lower than on the previous model. This helped the Prelude achieve a .34 drag coefficient – identical to the C4 Corvette
- 1990 is the first year of the B21A1 twin cam engine – the biggest engine ever offered on the 3rd generation Prelude. This engine replaces the B20A5 motor, producing slightly more power (5hp) thanks to 83mm more displacement (now 2.1L instead of 2.0L) and new fuel injection
- The B21 also introduces FRM cylinder wall liners (Fiber Reinforced Metal, which is also used in the 3.2L NSX engine). Most cylinder walls are made of iron, but Honda experimented with FRM as it provides less friction and has much better heat transfer qualities than iron, resulting in a more efficient cooling system
- FRM liners are smooth, with no “cross hatch” to assist with oil retention. Unfortunately, the reduced lubrication causes FRM liners to wear down quickly (as well as the piston rings), allowing oil to leak past the rings prematurely. FRM cylinder liners are not as strong as iron liners (but perfectly adequate for Honda’s intentions)
- Furthermore, if you want to bore out your FRM cylinder, it requires special stones (and it can only be bored out .02″ max). On top of all that, most aftermarket pistons are not compatible with FRM cylinder walls. Regardless, some of Honda’s most iconic engines use FRM liners
Key Model Year Changes:
- Mid-cycle facelift occurs
- First year of the B21A1 engine, providing an increase of 5hp. This is the first Prelude engine to feature FRM cylinder liners
- First year of OBD1 diagnostics (B21A1 powered Si models only)
- New ABS system, developed in-house by Honda
- 1990 and 1991 Si models are the only 3rd gen Preludes to feature the B21A1 engine
