Post 85.5, NA ....?

OK guys

Can somebody pls give me a brief descr. what a 85.5 is also a NA, 951 and other types .... Most of you guys seem to be Americans .... In Europe we have diff specs (or names). I know it sounds stupid - I also feel stupid not being able to talk about a 951 or NA's.... pls dont laugh - just a different part of the world. ( and I'm a newbie)

Regards to all - I Love this page ...

951 was the internal designation at Porsche for the 944 Turbo models. NA simply menas a naturally aspirated engine. The significance of the 85.5 model 944 was it was when they began producing them with the new dashboards which fixed some problems they had with air circulation in the heating and a/c systems.

revised dash style, raised stearing colum height for better leg room, revised center consel, flush mounted front windshield glass and major suspension components changed from steel to aluminium. Also, the radio antenna was moved from a front fender to being embedded in the front windshield. Some say the cars even had a bit more power

There are a number of differences pre and post 85.5 as por2chby pointed out. On the suspension, the front control arms were change post 85.5 to cast aluminum. While a bit lighter, they are also much more expensive to maintain. If a ball joint fails, you either have to buy a new arm $700+ or get it rebuilt $225+. The interiors were different as well. Of the 951s, the 86 is the most common and all of them respond very well to minor mods. It's very easy to get close to 300hp from these cars without breaking something expensive. Check out the 944 Webring, it's a great source of detailed info on the various models. I promise that you'll burn some time on it.

for more clarification - different variations:

924 (pre-944)
924S (reintroduction of 924 to US in 87)
931 (924 Turbo)
944NA (non-turbo 944, produced with 2.5 liter engine from 82-85.5, then 2.7 liters after 85.5)
944S (non-turbo 944 producing more horsepower, but supposedly less reliable and heavier)
951 (944 Turbo)
952 (944 Turbo S or Turbo SE)
944S2 (3.0 liter engined 944 with 951 bodywork)
968 (produced 1990-95, with new bodywork and the S2 3.0 liter engine)

the 85.5-88 are still 2.5. 89 is 2.7. The 87 (?) and higher have higher compression

A 85.5 is the same as an '86. 87"s have a few dif's, wheel offset and an auto adjuster on the cam belt and maybe a little more compression or the compression is maybe higher on the '88's not sure.
