COA Questions

[dpetteng]

So, I imported what I thought was a 2.2 911t when I moved back from the states. Its been 3 years and finally getting around to recommissioning and registering..

My COA says it is a 1970 911t Coupe. Does this mean it is a 2.0 or a 2.2?

I do not know how to decode my engine number 6107187?

Also, it says it had chrome whole disk wheels 5.5j x 15 but now it has 14" fuchs??? What are "Whole disk wheels"?

The engine # is a 1970 model. See attached. What size that is, I have no clue.

Hope this helps.

your 911 is 1970 911T with 2,0 engine...
Ivan

also look for the number on the case..like 911/20

[Arne2]

1970 and 1971 were 2.2, 2.0 went through 1969.

[dpetteng]

I'm confused!!

[proporsche]

Arne2 you are correct....i`m wrong....

Dpette ...it is after all 2,2...........

[dpetteng]

YES!!!! Thankyou.

So does anyone what wheels would be "chrome whole disk wheels 5.5j x 15"??

[proporsche]

It looks like there were 3 options

[racer]

1) Whole disk wheels = Steel wheels. Some had a chromed finish as well.
2) 1970 911t had a 2.2l motor. All 911's had a 2.2l motor starting in 1970.

The 1970 914/6 used the "old" T motor -2.0l displacement. A 911 with the same engine in the same year? heresy!

[dpetteng]

Awesome thanks. Interesting that a one owner car has a set of 14" such on it when they purchased it with steel wheels. I guess I could sell the fuch's and put steels back on!

[Arne2]

There are far more early 911s with Fuchs now than were ever built that way by the factory.

[dpetteng]

makes sense, I guess they are the quintessential porsche wheels

Also an easy swap by a dealer. Remember, a 911T was a price leader of sorts, so they could be find relatively light on options - 4 spd, steel wheels. A base 911T as only a couple hundred dollars more than a 914/6.

My dad's 914/6 came with steelies.. He had the dealer swap on 14" Fuchs (recall at the time, 14" was quite common size, 15" was a almost a premium size).

so, does anyone know what size tyres would be fitted to a 1970 14" comfort package? I am trying to get the right tyres but not sure which size to buy

They were likely 185/14. Back then, the default was an 80 series profile. You might find a 185/70-14 which is only slightly smaller sidewall.

I run 195/60 14 as there are one or two performance tires still available in that size. After that, at least in the US, you get less impressive touring/all season tires for your selection.

See the last post here is an old thread about the same topic:
What Size Tires on 14 Fuch

[dpetteng]

found a load of 185/80 14 yes in the UK. No Pirellis but just about every other make!

[SKL1]

Check the classic Pirelli CN36 sizes - try Stoddard.

[dpetteng]

Nope, seems Pirelli do not make the CN36 in the right size

[racer]

Michelin still makes some.. or at least Coker tire makes them using old Michelin molds.
A 205/70-14 would certainly fill up the fender wells better than most others.
