TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Comes from the factory with a 2.2”. Crank is 6.26.

 

Shhhhh

 

What is your max engine RPM?

 

I have microblue bearings on my idler pulleys. Those bearings are great for high speed. http://www.microblueracing.com/

 

Something like 6200 but it never gets there. Always shifts early at maybe 5800.

 

Yep. Had my superchargers bearings get the micro blue treatment too.

 

Any chance you have a list of the bearing numbers/locations? Also, did you go ceramic or stick with the steel bearings?

I looked at couple of them during the rebuild, on the tensioner bracket, looks like the aluminum grooved idler was OE NSK B17-402DG3, which translates to a 6303 bearing.
Also the steel upper idler was a

$9 6203-2RS 17x40x12mm Deep Groove Ball Bearing Double Rubber Seal Bearings Pre-Lubricated 4 Pcs

6203-2RS bearing. Need to locate the others to get a final count....

 

I’m not sure of the sizes for it’s been well over 5 years since installing them. But 6203 is definitely the tensioner pulley for the overdrive. And yes I got ceramic

I’m not sure if the bearing is a different size or not though cause I have the NST kit.

 

I got 10 years out the first set that came with the supercharger, but I did notice that a couple of the idlers felt a little rough and had some grease escaping. That’s not going to be good in the long run. I’ll have the access to the front of the engine this weekend, if I can’t find them sooner, I’ll get a full list together of p/n’

 

Your efforts would be appreciated.

 

Wonder if it would be wise to get a full rebuild kit and have a micro blue treatment done on the bearings? Just to have on hand so turn around times are minimal.

 

Ooooo. Santa sent motor jewlery. Yes, that cap is ridiculously priced.

 

I should stay out of this thread. I had to get a larger idler pulley for more belt tension and it has the 6203 bearing.

 

This is definitely a very expensive thread!

 

True. The only cheap part of a tacoma is Tacoma world. Then again it's the instigator for my account rape.

 

Ok curiosity definitely will kill me. What would the benefit be for that bearing swap? Better response? Less friction less belt slip? Less friction less heat?

 

Less energy loss can only make for potential gain. Be it reduced temps, part longevity, or more wheel spinning.

 

Silver is going on. I’m past color at this point. More powah!

 

Where you get it....how much??
