4th Gen TRD supercharger
Hi all,
New to the forum.
I do have a 2003 4.7L 4runner with TRD supercharger. I had it installed about 5 years ago when I had about 40k miles on the car. Now, after 65k miles with the supercharger, there is so far no major issue.
The car is running great. Definitely the best aftermarket performance mod that you can get. I believed situations with rod bending/blowing is when people start changing pulley size to up the boost or adding nos.
The 2 main issue I had was after initial installation of the supercharger, the serpentine belt kept fraying after few months. After swapping 2 belts within a 6 months period, I emailed TRD and they recommended to add the pulley shim kit. Since then, been without any further belt problem.
The second issue is recently noticed there is a leak from the nose drive of the supercharger. From reading online and info from Gadget (Toyota performance mod expert) realized that the nose drive will need to be change probably every 60-80k miles with replacement of lubricating oil inside nose drive.
TRD still have the entire nose drive assembly kit which cost about $220. Took 2 days (few hours/day) for my buddy and I to take out the supercharger and change the nose drive. Now the supercharger is running smooth.
Overall, my experience with the TRD supercharger is excellent.
I got mine 5 years ago, brand new for $3k when one of the California dealer was trying to get rid of their supply.
If you can get one, you can pretty much fit into (2000-2004)4.7L tundra, (2003-2004)4runner, (2001-2004)Sequoia. You just need to get unichip and have a shop program it.
I initially ran the supercharger with TRD ecu but since I had an unichip laying around, I took to a local shop and had them tuned it for my 4runner with supercharger. It ran way more smoother than the TRD ecu.
Hope this give you some idea. PM me if you have more question.
