Today i became the proud owner of 2 porsches, my second one being a 1989 944 automatic 3 speed tranny.

Some known issues about the car:

original Engine caught fire, another engine was sourced from a same year model. both Japanese origin cars.

current chassis number is WPOZZZ94ZKN401651, when i use Vin Decoder it shows the car had the 3.0L DME Engine.
The donor car's Chassis number is WPOZZZ94ZKN404260 which shows that the engine was a 2.5L DME Engine... i thought 89 models did not get 2.5L engines!?!

Now the previous owner of the car says he's sure it's a 2.7L engine... i tried to check the engine number but could only find the crank case number 944.105.250.7R

89 model 944 cars should have the engine number on the rear right hand side of the engine, but i couldn't find any other code.

2) the car vibrates a lot when idle and when in reverse gear... i read about rough idles on 944s, but this one shudders bad, not sure if it's normal.

3) when on the highway cruising, there's a rattling coming from under the shifter area, sounds like it's coming from the tranny..

i expected the car to have some issues, i'm just hoping it's nothing major like a full transmission change.


any feedback on the above would help.

Thanks

Off the top of my head:

2) balance shafts not indexed properly, bad motor mounts
3) transmission is in back of car between wheels. Could be shift linkage or perhaps something in torque tube/exhaust hangers (attached to torque tube)

Good luck

Does your engine look like this:

or like this:

Wasn't the 2.7 in '89 an 8v single overhead? So it would be the top picture correct? Since the dual overhead S morphed into the S2 that was sold at the same time as the car in question so the base model stuck with the 8v 2.7 I think.

A break down for you & the OP. ____944/83-88 -8v SOHC ___944/89- only 8v(2.7) SOHC___951 (TURBO)/86-89 8v SOHC ___944S/ 87-88 16v DOHC___944S2/89-91 16v DOHC___968/92-95 16v DOHC.

it looks like the top picture. it's the 2.7L i assume?
but what i'm saying is that could it be the 2.5L engine?

__Unless someone swap the motor for a 2.5 your 89 should be a 2.7.
