I appologize if this has been answered, but I could not find it on searches. What is the differences between the 87/88 and 89 up turbo 2 engines? The 89 up is more expensive and I was just trying to figure out if it is a better engine for my swap. Thanks

 

well what car do you have?.. s4 or s5

 

I have a SA 1985, 12a car.

 

well i guess its more up to you than... i know the rear iorn in the s4 tend to be a lil weaker than the s5 and the s5 has higher comperssion...

 

S4 is a mechanical OMP and the S5 is electronic. If it comes with the turbo then the S5 has the bigger wastgate.

 

turbo, turbo manifold, intake manifolds, omp, tps, housings are different, i believe the irons are different also. s4 has the twin scroll

 

oh, the front cover and rotors are also different

 

So, for 200 extra is the other one worth it?
