Differences between 95 MY and 96-99

Hey Gang,

Let's keep this a fact thread and not a $h!t storm. I'm still learning the differences and I think it would be nice to have a thread that defines them.

- 95's have no alarm or immobilizers (therefore no FOB's)
- 95's are OBD I, 96-99 are OBD II.
- related to OBDII, 95's do not have post CAT O2 sensors
- 95's do not have a post bypass valve thermocouple
- 95's do not have a glove box between the seats
- 95's do not rear bumper (black area) has no vents. 96-99 have slotted vents
- The secondary air pump in the 95 is a different design than others
- 95's have no access panels behind driver or passenger seats
- I've read (please confirm), 95's delivered to the USA had no option for stereo systems
- 95's do not have the riveted trim piece above the center tail light mesh panel
- 95's (maybe other years?) do not have thumb screws for the access panels under the front bonnet - they have snaps (my 98 has screws)

 

- mid-94 to early 1995 use 22mm wheel inserts. Later cars use 23mm.
- mid-94 - late-95 cars use dual fuel pumps. Later cars use single pump.

 

Thanks Daniel - that is something I needed to know for sure as mine are cracked...

 

Good idea Dave, and very worthy.

However, if this thread is still rooted in actual facts by the end of page 1 I'll eat my hat.

 

Different design on header collectors. On the 95 the bypass collectors merge inward.

Different bypass pipe. Y shaped on the 95.

Separate paths for the inlet boxes on the 95.

 

Do you mean mid 94 to early 95?

My 95 is a June Production and has single pump.

 

95s pull air to the engine through the C pillar.

Later cars pull through the door vent.

 

You sure about that?

-95's (maybe other years?) do not have thumb screws for the access panels under the front bonnet - they have snaps (my 98 has screws)


My 97 has snaps too so that might have been a change for the last couple years.

 

It is actually an engine # cutoff, so I can't pin it to an exact month -- and I'm not sure things were exactly linear in their engine->production month back then.

 

95's rear bumper has diffuser attachment brackets fibreglassed onto bumper
Later cars have selftapping screws that neatly attach the brackets.
Same arrangement for the silencer heatshield.

 

I believe that while the 5.2 cars have the ducts, they do not function in the same manner as the 2.7 cars

 

Two undertrays on a 95
Later cars had 3.... Ferrari split the main one into 2 pieces.

 

My late model 95 with single fuel pump has triple undertrays, fyi.

 

Correct, Ferrari changed that within the 95 production

 

Cylinder head castings were changed sometime in'95 model year as well.

 

The factory was not organised back then.

My UK August 1995 GTS has

2 fuel pumps
2 undertrays (since replaced with newer 3 trays)
Rear bumper with vents

 

What makes you think they're organised now?

 

What do you mean by this?

- 95's have no access panels behind driver or passenger seats

 

See the photo of my 98 - the panels shown are not present on 95's

Aren't the ecus behind them? On'95's the ecus are in the rear of the engine compartment under the rain shields so no need for the panels.

 

Thanks! and what are those for?

 

Behind the passenger seat (LHD), ECU. DRIVER's seat, immobilizer and F1 ECU

 

103154 has dual fuel pumps.

 

Are you sure about that? The fuel line recall 156 (not fuel block recall) which effected dual fuel pump cars, ended at assembly 19291 or S/N: 102548
