hello,
Wondering if some of you guys a have already fitted a 9000 B202 T (2.0fpt) on a classic 900?
what parts have to be changed to put a 9000 2.0 FPT on a classic 900 except the manifolds? is there any problems with the gearbox?

thanks

I always thought the block was a different shape in the 9000. the c900 block is tilted (because of the way that the bottom of the block is shaped) and the 9000 block is straight. I think the picture below shows a 9000 block on a 900 gearbox. It might be the case that the block shown here is a modified 900 block but I think it's a 2.3 9000 lump? not sure.

There is "early" 9k block identical to c900

there is also late 9k block identical to NG900.

B202 is same as c900 so no big deal.

Hell he can use the whole motor.

Just not if it's a 94+... but if he is talking of using a B202 - a B202 is a B202 is a B202. The later ones are B204...

If the motor is dismounted it is easy to see. The good one is bent in the middle like a 900 motor (which it is). The wrong one is pretty much straight up. The motor in a 9k is angled such that the top and bottom are not flat/

yes I am talking about the 9k 2.0 liter FPT B202 engine from the 80's

so what 9k year model engine will go perfectly to your thoughts? a saab mechanic who has tried told me it's not possible, others told me yes it's possible but they don't have tried.

it's the first reason
I have the possibilty to get a remanufactured B202 T engine with 0 miles from a 9k for a real good price, I would like to fit it to my hardly modified classic 900 just to have a new engine.

the 9000 2.0 engine from 85 to 93 will fit a c900 but you need to replace the timing chain cover (which has the oil pump on it) and the oil pick up as well as the plate at the clutch end of the block, also if your fitting an early 9k engine you will need to fit the 900 cam cover and if fitting a later 9k engine you will need to fit the dizzy and replace the crank pulley

THe 9000's around 1991 got the 2.3 liters so they are B234.

I don't think you'd need a different cam cover. The cam covers are all the same in the important areas. It's just different styles. When you have DI they plug the dizzy hole with either a rubber or an aluminum plug. Some 9000's already have a dizzy though.

Do it. If you see anything that is radically different, take it off your current motor. The big stuff is identical.

not true, the very early 9000 cam cover was not slopping like the 900 one, it was the same depth all the way accross the head so the 900 bonnet will not close with this cam cover

alright - but generally speaking (unless it's a very early 9000) you wouldn't need to change the cam cover
no thats right, i think the early cover was replaced with the sloppey one around 87 so it would be a very early 9000

ok , so replacing the timing chain cover the oil pick up, the plate, and maybe dizzy and crank pulley and the engine will go into the c900 perfectly?
It doesn't seem very complicated I don't understand why the saab mechanics I know who tried to do it didn't succeed.
