Why do I need a new exhaust manifold, the bolt fittings on the Saab TD04 and T25 looked identical, I compared the two, will need to rotate the compressor housing 90 degrees or so, but not sure about the exhaust elbow.
But size wise, they looked similar and most important for me wanting to retain the standard exhaust manifold the bolt fitting was the same.
Tell me if I have missed something...
I have both a T25 and a TD04 to choose from, both from saab... the TD04 is more modern technology and I am assured by my mapping guy that it will spool up a little faster and keep the boost longer...
But with 2 weeks to get this baby ready... all advice and opinions are both welcome and appreciated.
Mike.
