98 Spec JDM V's 96 Spec JDM (Taken from Type R Legends DVD)
I have listed the differences between the 96-98 Spec JDM ITR's below, as taken from BMI's Type R Legends DVD. As you can see it is quite long so you may not want to read it all. Please bare in mind that this is Japanese translated into American, I have changed some of the more obvious facts into UK English and that it is BMI information not mine, so if you don't agree with the facts complain to them.... Razz
This list does not include all the Track Battles and extras on the ITR that are on the DVD so I recommend a purchase!!! Very Happy Very Happy Very Happy
1. HID lights on 98 Spec (added weight, but improved night visibility)
2. The most siginficant change are the wheels
96 Spec 195/55/15 4 stud
98 Spec 215/45/16 5 stud (rare tyres....)
3. Brake Discs enlarged
96 spec Front 14" Rear 13"
98 spec Front 15" Rear 14" (I don't know if this is correct as I thought these were mean't to be the same as the UK spec fronts, but the UK spec wheels are only 15")
4. Front Suspension - Modified to increase cornering speeds after extensive testing on the circuit.
96 Spec
Spring rate (KGf/MM) 4.4
Damper (KGf) (Full) 245
(short) 161
Anti Roll Bar (inches) 0.94
98 Spec
Spring rate (KGf/MM) 4.5
Damper (KGf) (Full) 231
(short) 142
Anti Roll Bar (inches) 0.98
5. Rear Suspension
96 Spec
Spring rate (KGf/MM) 4.4
Damper (KGf) (Full) 118
(short) 70
Anti Roll Bar (inches) 0.87
98 Spec
Spring rate (KGf/MM) 4.5
Damper (KGf) (Full) 100
(short) 59
Anti Roll Bar (inches) 0.91
This seems to indicate that Honda decided to increase the stiffnes of the spring slightly but decrease the dampening of the shocks. Also the anti roll bars were thickened. Perhaps someone who knows more about this can explain..... Wink
6. The 98 spec engine was equiped with an all stainless steel manifold giving the engine more torque at lower revs.
96 Spec - 200 ps @ 8000 rpm
18.5kgm @ 7200 rpm
98 Spec - 200 ps @ 8000 rpm
19kgm @ 6200 rpm
7. Other Specs
96 Spec
Height (inches) 52
Rear Track (inches) 57.9
Weight 1060kgs
ABS Option
Airbag Option
98 Spec
Height (inches) 52.4
Rear Track (inches) 58.5
Weight 1100kgs
ABS Standard
Airbag Standard
8. Engine Internals (Enlargement of the thrust bearings, Ports, and Valve Seals) were machined by hand until late 96 spec engines. When it came to improving this process further it took to long by hand, so the engineers were replaced by machines.......
Late 96 spec and 98 spec engine internals were machined by specialist machines that produced work that was so good it was impossible to match by hand.....
9. Quarter mile race between the two models with gearbox ratios as described above.... Very Happy
Gear Ratios
96 Spec
1st - 3.230
2nd - 2.105
3rd - 1.458
4th - 1.107
5th - 0.848
Final 4.4
98 spec
1st - 3.230
2nd - 2.105
3rd - 1.458
4th - 1.034
5th - 0.787
Final 4.785
This all means that 1st, 2nd and 3rd gear are shorter in the 98 Spec (due to the closer ration of the Final drive), but 4th and 5th are wider for top speed...... (i.e. 4th and 5th in the 96 Spec are closer for acceleration, which is why the 96 Spec pull the 98 Spec back in 4th gear in the 1/4 mile)
10. Braking test from about 95 mph
96 Spec (non ABS) - 269.7 ft
98 Spec (ABS and larger discs) - 230.3 ft Shocked
11. Circuit Battle (in postion order with lap times)
1. 98 Spec Integra - 1.09.16
2. MR2 G liimted (200ps non turbo) - 1.09.57
3. Celica (T-Sport?) - 1.09.65
4. FTO (Version R?) - 1.10.14
5. Miata - 1.13.45
6. BMW Z3 - 1.13.94
Driver comments - It a stable ride.... There is only a slight improvement in quickness, but the brakes and tires really contribute to the stable lap times.....Its a driver friendly car.... I guess the gear ration has some demerits at top acceleration.... but the 1st 2nd and 3rd gears match the circuit. (1st 2nd and 3rd are shorter on the 98 spec, but 4th and 5th are wider for top speed....) The new ITR (98 spec) is a fine car.....
The ITR is great for low and mid speed courses.... older ITR's had problems with the 1st and 2nd hairpins you couldn't rev the engine enogh for those corners.... but now the second gear is a perfect match
12 Endurance race
The 96 Spec ITR is raced (earlier on) in the Endurance race and it wins on lap consistancy.
The 98 spec ITR is raced in the endurance race (not sure who won this one), the oil temp goes through the roof.... cut to Spoon who say when their cars are on track they use Stock Honda Logo oil filters which fit but are smaller and prevent oil pressure fluctuation (preventing warping of the oil filter case). They also put baffles in the sump and heat tape between the exhaust manifold and the sump to further prevent the oil pressure fluctuating. They also use steel gaskets and steel banding around their oil filters on their racing cars....
Spoon then go on to suggest that if youre driving a 96 Spec ITR with over 60,000 miles (on track I presume) when rebuilding the engine also change the raer suspension arm to a 98 spec (or 2000 spec) version for a milder ride and easier handling. All bushes are compatible between 96 spec, 98 spec and 2000 spec so go for the latest you can get.... before making major mods Spoon recomend changing these small parts to enjoy the circuit more first....
13. 2000 spec ITR differences (I don't think there is a 2000 spec ITR as such but its just that Honda was alway making fine adjustments upto the end of the production run.... similar to say the S2000 production run....)
The drive shafts, hubs and bearing have all been syncronised (machined!?!) for better movement, which is the kind of precision work Honda have been doing for the past year or so... (The DVD came out in 2001)
96 spec discs are 262mm
98 spec discs are 282mm
The UK Gear ratios are in the broucher, they are the same as JDM98 ratios.
Official Weights of JDM98 are
Honda??????????? Honda???????...
Base Model = 1,080 kg
+ABS = 1,090 kg
+ABS+SRS air bag = 1,100 kg
+air con+ABS+SRS air bag = 1,120 kg
UK Official Weights
1,110 kg
UKDM or EUDM or JDM compression ratio - 11.1:1 (catalogue figure - 11:1)
USDM compression ratio - 10.6:1
Differece is on the piston dome displacement.
P73-A0 pistons for US and P73-00 pistons for the rest of the world.
UK Honda workshop manual states:
Section 3.9, Design Specifications, Kerb Weight 1120kg, w/SRS 1130kg-
JDM DC2:
Vehicle Weight: 1060Kg
ABS Equipped: 1070Kg
SRS Airbag Equipped: 1070Kg
ABS + SRS Equipped: 1080Kg
Air Conditioner will add a further 20Kgs...
My '96 4 door DB8 Type R starts at 1100Kgs and I only have air con = 1120Kgs! the 98 equivalent weighed in at 1160Kgs with everything fitted.
Bearings and hubs were different:
96 JDM - smaller front and smaller rear bearings (4 stud hubs)
98 JDM - larger front and larger rear bearings (5 stud hubs)
UK/Euro/US - smaller front and larger rear bearings (5 stud hubs)
The bearings have a significant influence on the camber rigidity of the whole corner assy.
Manifolds and cats were different:
96 JDM - 4:2:1, 4:2 part cast, 2:1 part fabricated with 65mm OD collector.
98 JDM - 4:1 one-piece fully fabricated with 65mm collector.
UK/Euro/US - 4:2:1 two-piece fully fabricated with 51mm OD collector.
JDM used shorter cat ~305mm, UK/Euro/US cat ~445mm.
From experience 96 JDM cars have different steering to UK cars too. The UK cars have variable resistance with torque and speed. 96 JDM steering is much lighter with less feed-back. Also brake pedal feel is completely different between these two models - down to more than disc size alone.
I dont know if this has been covered elsewhere but i spotted it on another site (in which the author also had itr-dc2.com as a link in his signature so maybe he found it here, but i dont know in what thread. Anyway its the differences in the Integra Si/GSR and the ITR. Its from a US site and so compares the GSR to the US ITR which didnt get recaros and had different wheels to the UK ITR but basic differences in structural parts and engine parts are the same for the Si-v-ITR (UK and JDM)

8. Engine Internals (Enlargement of the thrust bearings, Ports, and Valve Seals) were machined by hand until late 96 spec engines. When it came to improving this process further it took to long by hand, so the engineers were replaced by machines.......
Late 96 spec and 98 spec engine internals were machined by specialist machines that produced work that was so good it was impossible to match by hand.....
9. Quarter mile race between the two models with gearbox ratios as described above.... Very Happy
Gear Ratios
96 Spec
1st - 3.230
2nd - 2.105
3rd - 1.458
4th - 1.107
5th - 0.848
Final 4.4
98 spec
1st - 3.230
2nd - 2.105
3rd - 1.458
4th - 1.034
5th - 0.787
Final 4.785
This all means that 1st, 2nd and 3rd gear are shorter in the 98 Spec (due to the closer ration of the Final drive), but 4th and 5th are wider for top speed...... (i.e. 4th and 5th in the 96 Spec are closer for acceleration, which is why the 96 Spec pull the 98 Spec back in 4th gear in the 1/4 mile)
10. Braking test from about 95 mph
96 Spec (non ABS) - 269.7 ft
98 Spec (ABS and larger discs) - 230.3 ft Shocked
11. Circuit Battle (in postion order with lap times)
1. 98 Spec Integra - 1.09.16
2. MR2 G liimted (200ps non turbo) - 1.09.57
3. Celica (T-Sport?) - 1.09.65
4. FTO (Version R?) - 1.10.14
5. Miata - 1.13.45
6. BMW Z3 - 1.13.94
Driver comments - It a stable ride.... There is only a slight improvement in quickness, but the brakes and tires really contribute to the stable lap times.....Its a driver friendly car.... I guess the gear ration has some demerits at top acceleration.... but the 1st 2nd and 3rd gears match the circuit. (1st 2nd and 3rd are shorter on the 98 spec, but 4th and 5th are wider for top speed....) The new ITR (98 spec) is a fine car.....
The ITR is great for low and mid speed courses.... older ITR's had problems with the 1st and 2nd hairpins you couldn't rev the engine enogh for those corners.... but now the second gear is a perfect match
12 Endurance race
The 96 Spec ITR is raced (earlier on) in the Endurance race and it wins on lap consistancy.
The 98 spec ITR is raced in the endurance race (not sure who won this one), the oil temp goes through the roof.... cut to Spoon who say when their cars are on track they use Stock Honda Logo oil filters which fit but are smaller and prevent oil pressure fluctuation (preventing warping of the oil filter case). They also put baffles in the sump and heat tape between the exhaust manifold and the sump to further prevent the oil pressure fluctuating. They also use steel gaskets and steel banding around their oil filters on their racing cars....
Spoon then go on to suggest that if youre driving a 96 Spec ITR with over 60,000 miles (on track I presume) when rebuilding the engine also change the raer suspension arm to a 98 spec (or 2000 spec) version for a milder ride and easier handling. All bushes are compatible between 96 spec, 98 spec and 2000 spec so go for the latest you can get.... before making major mods Spoon recomend changing these small parts to enjoy the circuit more first....
13. 2000 spec ITR differences (I don't think there is a 2000 spec ITR as such but its just that Honda was alway making fine adjustments upto the end of the production run.... similar to say the S2000 production run....)
The drive shafts, hubs and bearing have all been syncronised (machined!?!) for better movement, which is the kind of precision work Honda have been doing for the past year or so... (The DVD came out in 2001)
96 spec discs are 262mm
98 spec discs are 282mm
The UK Gear ratios are in the broucher, they are the same as JDM98 ratios.
Official Weights of JDM98 are
Honda??????????? Honda???????...
Base Model = 1,080 kg
+ABS = 1,090 kg
+ABS+SRS air bag = 1,100 kg
+air con+ABS+SRS air bag = 1,120 kg
UK Official Weights
1,110 kg
UKDM or EUDM or JDM compression ratio - 11.1:1 (catalogue figure - 11:1)
USDM compression ratio - 10.6:1
Differece is on the piston dome displacement.
P73-A0 pistons for US and P73-00 pistons for the rest of the world.
UK Honda workshop manual states:
Section 3.9, Design Specifications, Kerb Weight 1120kg, w/SRS 1130kg-
JDM DC2:
Vehicle Weight: 1060Kg
ABS Equipped: 1070Kg
SRS Airbag Equipped: 1070Kg
ABS + SRS Equipped: 1080Kg
Air Conditioner will add a further 20Kgs...
My '96 4 door DB8 Type R starts at 1100Kgs and I only have air con = 1120Kgs! the 98 equivalent weighed in at 1160Kgs with everything fitted.
Bearings and hubs were different:
96 JDM - smaller front and smaller rear bearings (4 stud hubs)
98 JDM - larger front and larger rear bearings (5 stud hubs)
UK/Euro/US - smaller front and larger rear bearings (5 stud hubs)
The bearings have a significant influence on the camber rigidity of the whole corner assy.
Manifolds and cats were different:
96 JDM - 4:2:1, 4:2 part cast, 2:1 part fabricated with 65mm OD collector.
98 JDM - 4:1 one-piece fully fabricated with 65mm collector.
UK/Euro/US - 4:2:1 two-piece fully fabricated with 51mm OD collector.
JDM used shorter cat ~305mm, UK/Euro/US cat ~445mm.
From experience 96 JDM cars have different steering to UK cars too. The UK cars have variable resistance with torque and speed. 96 JDM steering is much lighter with less feed-back. Also brake pedal feel is completely different between these two models - down to more than disc size alone.
I dont know if this has been covered elsewhere but i spotted it on another site (in which the author also had itr-dc2.com as a link in his signature so maybe he found it here, but i dont know in what thread. Anyway its the differences in the Integra Si/GSR and the ITR. Its from a US site and so compares the GSR to the US ITR which didnt get recaros and had different wheels to the UK ITR but basic differences in structural parts and engine parts are the same for the Si-v-ITR (UK and JDM)
EDIT BY NEBPOR: NOTE THAT UK CAR HAS SAME COMPRESSION RATION AS JDM CARS, NOT USDM - ENGINE IS NOT THE SAME BETWEEN UK AND USA
