I have some other mods that also help.

Ported exhaust manifolds
Smooth wall tubing instead of accordian tube
Peeeeeeeerfect flow matched injectors
Ported TB (aka shaved throttle shaft) Might get polished when it'* off.
High flow cat

Other items
Fresh fuel pump and filter
1 year old LIM gaskets
New waterpump
All new pullies
Fresh muffler

Sounds like you're ready to rock and roll, Boosty.

Now pop on that 3.2 and burn some rubber.

Ohhhhhhh boy.

Ok.. just got the bearings out of the casing. Much harder than Wren had mentioned...off to check his post to see if he had the same issues I did.

I'm back.

See BW'* post on how to do it. HERE

The Gen 3 M90 is a little different and poses a couple challenges.

Off to get pics..

Who is ready for reasonable sized pics?

I looked over Bill'* M62 pics. The M90 looks to be more of a challenge.
Let'* review...
The location of the holes on the M62 are evenly distributed away from the sidewall areas. Bill W'* pic

The M90 has one hole that is nearly part of that sidewall (Grease in holes)


An NPT tap is about 2 inches in length. The distance to the bottom of the SC is about 2 inches. The tap is hardly in the hole. It was a challenge. I will not say how I pulled it off because I can not suggest others follow the method.

The last challenge was not finding a NPT grease fitting at 1/8". I happened to notice that the standard grease gun hose thread size was 1/8" NPT one thing was on my side.

Now for fun... 4 inch pipe to stick out enough.


Only in a couple threads

You can get a longer tap, or use a better tap handle to reach in there.

Not when that tap is up against the side of the casting you can't. You'll see soon enough. Wasn't fun..got it done.. should be sleeping..lol

It'll be interesting to see. Most M90'* follow the same procedure with great success, and no difficulties.

I used the same procedure and didn't have difficulty. I'm merely saying.. there'* no room for error up against the side casing.

Hit a snag. Was in the process of reassembling all the parts on the polished SC and realized I forgot something. The two bottles of SC oil that I keep on hand were used to change the oil before I went to Oregon. Forgot I used them... new sc won't go on this weekend.

Well, go to the dealer and get some!

Locked doors usually present a problem with purchasing it.
