My 88 doesn't have 150mph speedo, has it likely been changed?

150mph speedo came late in 1988. Early 88's still had 85mph speedos.

I suspect the changeover for the small diff mount bolts to the large diff mount bolts coincided with the switch from narrow tunnel to wide tunnel floorpans.

The cloth interior was different in 85 than it was in later years. It had that grid pattern on it.

In 1988 and 1989 moonroofs were standard.

Thats the "window pane"

From above, looks like

Cloth interior changed from Window pane to Herringbone

needs moved from 1987 to 1986.

Nope. Extremely rare to have an 88-89 non-sunroof car, but I have an original window sticker here from an 89 XR with:

TILT/SLIDE SCREENED MOONROOF 549.00

In the Optional equipment list, not standard equipment.

White trim in the trunk area on early cars.
My 87.5 has the same valve cover as 85-86
Rear hatch windows vary (defroster grid, etc) somewhere b/t 85-87

Update:
85 no third break light.

I second this, my 86 had herringbone.



Also, shouldn't there be something on the cladding trim color? Some had red metallic, some were silver, and some were black.

Sometime in 87 they switched from a single diaphragm booster to a dual diaphragm booster and also increased the size of the master cylinder.

I found an early 85 had a different door handle material, they were a softer one piece handle instead of the harder plastic 2-piece. In the same car I found a factory hatch release button in the center console.

Thanks for the input everyone,

Added "Late" to 150mph speedo's on 88's
Moved non-cracking dash material to 87.5
Moved Diff mount to 86 Late
Moved cloth interior change to 86
Moved valve cover redesign to 87.5
Added brake upgrade to 87



Questions:
Does anyone have a 88/89 without a sunroof? It may have been listed as optional on the sticker, but could have been on every car.
On the same note, was cruise standard on the 88/89's?
I think all cars had red cladding trim from 85-87?, then I've seen white 88's with both Red, Black and Silver trim. Anybody with an 87 with non-red trim?
On the different door handle/hatch release, does anyone else have an early 85 with these features? My early 85 has some differences, doesn't have these. Could these just be imported euro parts?

some door handles were metal and some plastic there's pics at merkur tech.

There was a plug change in the wiring harness I believe in 87 over by the master cylinder.

Grayson has a white 5spd 88 XR with no sunroof, I think blugg has (or had) a red 89 shell with no sunroof, I've personally owned a silver auto 88 with no sunroof.

No. Listed as an option both years. Its very likely that most late 88's and virtually every 89 has cruise from the factory, but it was not standard equipment.

Very early 85's with 84 yr build dates had the door handles that had a metal mounting base instead of the plastic ones used there after. Metal base euro Sierra door handles were metal base from 82-85, then went to the same plastic base ones we all know and love.

Couple of questions:

Was the Air Baffle on the T-9 standard or a late change? Same thing with the big weight on the rear of the tranny? Neither of my 85's have these, my former 88 did.

Does anyone know what year they added the plastic cover on the fuel tank?

Can anyone confirm that early 85's came with 30# "Green Top" injectors?

I'm going to assume that the E6 was a late change, since those 86's made in 85 wouldn't have the change?

Added Change: Metal Base Door Handles 85 Early

There was a thread on here a few years back discussing "early" and "late" XR4Ti T9's. I can't remember the details exactly, maybe someone else will chime in. I think one of the fireant racing guys had a write up with pics if I remember correctly...
grondie wrote: Does anyone know what year they added the plastic cover on the fuel tank?
My understanding is that it was there on every year XR from the factory.
grondie wrote: Can anyone confirm that early 85's came with 30# "Green Top" injectors?
Definately NOT. ALL XR4Ti's had brown toppers. Early Turbo Coupe and early SVO had greens, but never an XR4Ti.

Every 86 I've ever owned (maybe 9 or 10) or seen (maybe 50) has had a factory E3 manifold. Early 87 is the first thing I've seen come with an E6. Cannot say this is 100% accurate, but I'm at least 98.5% sure 87's were the first car with an E6. Same with turbo Coupes, the 87 was the first one to see an E6 manifold. And the SVO never got an E6, ending its production in 86. etc.
Also, as you've noted most 1986 MY XRs have 1985 build dates, so hard to have an E6 (86 casting) part on an 86 built in 85...

As I remember the big change on the T9 as discussed a while back was the bellhousing..



There were also a few very early 85's with the hatch unlock under the armrest. Ive seen one myself.

Were manual windows offered on all years? I had an 85 with manual windows but all the rest of the options.

What about the changeover on the steering rack? Anyone know a date on that?
Merkur....Its German for Mutt....Mustang, Saab, Volvo, Lincoln, Contour, Cummins... and the list goes on.
