I have a turbo replacement underway.
The T25 turbo in the car ('97 9k CSE turbo) with 165k miles has a blown internal oil seal and very worn thrust bearing.
The donor turbo came from a '99 9-3. The internals (T25)all match with one exception.
The original turbo had a larger coolant inlet banjo bolt fitting (13mm head) vs. a smaller banjo bolt on the donor (12mm). Can I use the smaller banjo bolt with the larger metal pipe fitting, or will it leak?
The thread end diameter of the original turbo banjo bolt is about 13mm.
The coolant pipe banjo bolt opening is about 14mm. (The larger bolt won't fit thru it)
If this is an unacceptable fit, is it possible to source and purchase a coolant pipe to fit this smaller opening and banjo bolt, running from the end of the cylinder head down to the back of the turbo??
Or is it possible to obtain a banjo bolt with the smaller diameter (12mm) threaded section with a wider upper bolt body (13mm)?
Thanks for any help!
