SECTION 4H - VT SERIES 195 kW V8 ENGINE

CAUTION:

This vehicle will be equipped with a Supplemental Restraint System (SRS). A SRS will consist of

either seat belt pre-tension ers and a driver’s air bag , seat belt pre-t ensioners and a driv er’s and front

passenger’s air bag s or seat belt pre-tensio ners, driver’s and fron t passenger’s air bags and left and

right hand side air bags. Depending upon the system fitted, refer to SAFETY PRECAUTIONS, Section

12M Supplemental Restraint System in the VT Series I Service Information, before performing any

service operation on or around any SRS components, the steering mechanism or wiring. Failure to

follow the SAFETY PRECAUTIONS could result in SRS deployment, resulting in possible personal

injury or unnecessary SRS system repairs.

1. GENERAL INFORMATION

This Section of the Holden By Design Service Information Supplement describes the components employed in

the 195 kW V8 engine upgrade.

The 195 kW V8 engine has been developed by Holden Special Vehicles and includes mechanical revisions -

cylinder heads, camshaft, etc., a revised air inlet system and a new exhaust system. A recalibrated powertrain

management is also incorporated.

Together, these modifications increase the power output to 195 kW @ 4600 rpm and torque output to 430 Nm

@ 3800 rpm.

Mandatory with the 195 kW engine upgrade on Executive and Berlina models is the fitment of ‘V’ rated tyres.

A Holden By Design identification plate and 195i badging completes the package.

Figure 4H-1 illustrates the 195 kW V8 engine major components.

For information not contained in this Section, refer to: Section 6A2, V8 ENGINE in the VT Series I Service

Information, Section 6C2 POWERTRAIN MANAGEMENT-V8 ENGINE in the VT Series I Service Information,

Section 10 WHEELS & TYRES in the VT Series I Service Information.

2. ENGINE

The com ponents fitted to the 195 kW V8 engine that differ to the standard Holden V8, as shown in Figure 4H- 2,

are:

• Cylinder head (1),

• Exhaust valve spring (2),

• Stainless steel valve spring seat (3),

• Exhaust valve (4),

• Fuel rail cover (5),

• Throttle body cover (6),

• High-lift, high-duration camshaft (7),

• Timing chain and steel sprockets (8-10),

• Timing chain damper (11).

The modifications are designed to improve the engine’s breathing and ensure it copes with the power increase.

The engine throttle body cover, rocker covers and fuel rail covers are coloured flame red. The fuel rail covers are

also fitted with ‘195 Sequential Injection V8’ labels.

195 kW V8 engines are identified by the engine option code LB9 & XX3, which is stamped into the vehicle

identification plate. Also, the engine number is prefixed by the letters VN. The engine number is located on the

LH side of the cylinder block above the oil pump housing.

The procedures and specifications required to service and repair the Holden By Design 195 kW V8 engine are

the same as for the standard VT Series Holden V8 engine, refer to Section 6A2,V8 ENGINE in the VT Ser ies I

Service Information, except for the camshaft specifications which are listed on the next page.

3. INLET SYSTEM

A newly designed cold-air inlet system, which has

been optimised for the 195 kW engine is fitted.

Changes from the standard air inlet system include a

free f low inlet snork el (1) and a revised airbox (2). All

other com ponents, including the air filter, ar e st andard

VT Series V8 components.

Service procedures are the same as the standard V8

engine inlet system. Refer to Section 6C2,

POWERTRAIN MANAGEMENT-V8 ENGINE in the

VT Series I Service Information.

Figure 4H-3

4. EXHAUST SYSTEM

A totally new exhaust system is used in place of the

standard VT exhaust. It is a low restriction, free

flowing system which reduces back-pressure and

improves engine breathing. Tubular header type

exhaust manifolds as shown in Figure 4H-4, replace

the standard engine’s cast iron manifold.

Due to different lengths in wheelbase between sedan

and wagon variants, the intermediate muffler

assembly’s front pipes are approximately 150 mm

longer for wagon.

5. POWERTRAIN MANAGEM ENT

Changes to the powertrain management system for

the 195 kW V8 include the fitment of a revised

Powertrain Control Module PROM unit (1).

Service proc edures f or the Holden By Des ign 195 k W

V8 powertrain management system are the same as

the standard VT Series V8 powertrain management,

6. ‘V’ RATED TYRES

With the installation of the 195 kW V8 engine, VT

Executive and Berlina models are fitted with ‘V’ rated

tyres on the standard steel rims, unless alloy wheels

are optioned.

The standard tyre placard (1) is replaced to ref lect the

changes.

Service procedures for the wheels and tyres are the

same as the standard VT Series vehicles. Refer to

Section 10, WHEELS & TYRES in the VT Series I

Service Information.

7. IDENTI FICATION & BADGING

Vehicles fitted with the 195 kW V8 engine, receive a

unique 195i decal, which is placed in the positions

shown in Figure 4H-11.

All sedan m odels ex cept SS, have the dec al af fixed to

the RH side of the deck lid as shown

SS models have the decal affixed to the LH side of

the deck lid as shown

W agon models have the decal affixed to the RH side

of the tailgate as shown

Figure 4H-11

A HBD identification plate is also installed onto the

radiator support panel with pop-rivets.
