you wont miss those parts, steering feel is way better
A million times this. I only put about 1200 miles on mine in 2wd mode before I tore it back apart to redo the fueling and larger turbos but in that time I can tell you the feeling felt soooo much better.
I'd highly recommend it. I had my car for a few thousand miles with RWD and no LSD....not very confidence inspiring to say the least. Adding the Wavetrac diff made a huge improvement.
Thanks everyone, not sure yet what Gordon will recommend for break in mileage.
Don't baby the break in Keith. That's the worst thing you can do. This is what we've always used with success after a fresh build:
1: Use 0W40. Pre-prime engine for oil pressure (pull your fuel pump fuse)
2: Start the car on the rack and verify you have oil pressure
3: Allow the engine to fully warm up checking for any leaks and check for normal throttle response
4: Shut off engine and do an oil change with 5w50
5: Drive the car with varied throttle inputs and do a few pulls to redline with an off throttle coast down. Datalog to get a good baseline tune
6: Dyno the engine to get the tune optimized and datalog a few pulls on the street.
7. Drive it like you stole it
8. Change oil again at 500 miles
Luckily the prior owner had the 2nd gear issue taken care of during their time with the car and everything seemed to be in good order with regard to shifting etc. Autometrics did add a Guard LSD for me while the driveline is out. Very interested to see the difference in driving experience.
