i bought a series IV TII that was wrecked for the purpose of transplanting the engine into my series V NA. but i dunno if its worth the hassle. ive got my NA engine apart right now, and ive gotta replace all the seals and basically do a full rebuild. so, what do you guys think i should do? rebuild and port my NA series v engine, or drop in the series IV TII and swap over all the stuff. what do u think?

 

If I had a wrecked turboii car and a n/a car with the engine out and apart, no parts bought yet, I'd swap the turbo parts into the n/a. Crate all the engine parts of the na with a protective film of grease and store them for *just in case*.

 

does it matter if it a series 4 going into a series 5?

 

No matter what, it'd be nice to put the TII drivetrain in the N/A, so you have a beefier platform with with to work.

Especially if the TII mileage is lower than your N/A's.
