Engines
Author: PurdueGuy
There are 3
Major Types of Engine for the S-Series:
LK0 -
SOHC, TBI ('91-'94) 85 crank HP
L24
- SOHC, MPFI ('95-'02) 100 crank HP
LL0 - DOHC, MPFI
('91-'02) 124 crank HP
SOHC = Single
Overhead Cam (one cam controls intake and
exhaust valves)
DOHC = Dual Overhead
Cam (separate cams control intake and exhaust valves)
TBI = Throttlebody
Injection (one fuel injector, housed in the throttlebody)
MPFI = Multiple Port
Fuel Injection (multiple injectors, housed in the
intake manifold)
There are 3
Major Types of Engine for the S-Series:
The LL0 (DOHC) is easy to spot, due to the
different valve cover. To differentiate between the 2 SOHC
engines, look behind the valve cover at the intake. The
LK0 (TBI) has the air filter behind the valve cover, by the
firewall. The L24 has the airbox by the radiator support.

L24 (MPFI SOHC)
