How to distinguish from....
How can I distinguish engine wise from a Turbo S4 to S5. I need to buy a rotor and I do not know if this engine an S4 or S5.
Thanks
Thanks

S5 will have an electrical MOP is probably the easiest check

Thanx for the info ... But I am very confuse or I have an S4 with S5 rotors. I weighted them and the rotors were about 9 lbs and 10 onz. I have had this engine since July of 2004 and I did not know the year of it. I have heard of people putting S4 rotors to an S5 but not S5 to S4 what should I expect from this engine been an S4 with S5 rotors?

According to this
http://fc3spro.com/TECH/FAQ/ZVK/zvk.html
My engine is an S4 (Intake manifold is the short style, One TPS, Turbo passages are asymmetrical.) But the rotors for some reason are S5.

s5 rotors are lighter and is one of the reasons why the s5 produced a higher rpm and more power. Im sure youll be fine with those rotors in the s4, becuase ive heard of those being interchable. It would be considered an upgrade to have s5 rotors in a s4 engine.
- Oh edit.
the s4 rotors are more durable and can handle higher hp applications and is the reason why some ppl seek s4 rotors in there s5 motors or use them in racing engines.

As long as you're using the correct / matching counterweights / flywheel, you are able to change rotors like that without any problems.
You have the engine apart?

I was about to say that ...
I use s4 rotors in my highly modified s5 block. They can handle a lot higher boost applications. Granted this is if you plan to run 20+ psi. If not, I'd stick witht he s5 rotors, theyll produce quicker response from their higher compression.

The motor is street ported and I will be using a Wolf 3d ver 4 standalone. In witch all of it is going into a 1st gen body.
