Been working on the intermediate shaft axle conversion.

I guess I should have posted some pictures of my initial measurements:

Used some 0.750" spacers to mount the IMS housing so I didn't have to pull the axle seal to test fit.



First iteration mounting plate, taking advantage of bosses on the side of the Northstar block



Initial mounting plate design will result in negative clearance to the side of the CV joint tulip

If anyone cares, Will drove my stock '12 Camaro SS manual (LS3) the other day (including 0-120+mph twice). He said that his N* Fiero does feel a bit stronger throughout, which is what I expected considering the weight/power ratios. Unfortunately his car was down for the above mentioned so I didn't get to drive it, but soon, hopefully! We'd like to take them both to the strip soon. I'm not expecting to break any records with the SS, but it should run easy 12's (unfortunately my 11-second AWD Talon ruined me, anything that can't launch as hard and runs slower than 11's while still being able to handle with the better-of-them is, honestly, a bit of a disappointment).

The N* Fiero is pretty darn quick if it's faster than an LS3 SS, and he's not even close to being done with the mods.

are the IMS's specific to the transmission they are bolted to? ie: could I use an IMS like yours on an F23 or a Muncie?

The Type I IMS with the cast aluminum housing is specific to the 282. The Type II IMS (not pictured) can be used with any transmission that uses the Fiero right side axle.

However, the Type II needs a much more robust support bracket bolted to the side of the engine than the Type I.

Thanks for the info, any other reasons you are installing one other than to get the C/V tulip out of the heat?

1. The heat
2. There's a boss on the side of the block that's used to secure the original under/over pipe from the front bank exhaust. This boss rubs the CV joint boot and eventually rubs through and causes it to fail and sling grease everywhere. I didn't feel like cutting this boss off.

Will, did you have that happen? I have just under 1/4" clearance there and I am concerned about the tripot boot expanding at speed or flexing enough to rub on that boss with my Isuzu setup. Was your clearance similar, just enough to think it might work?

The 282 and Isuzu may put their axles in slightly different places, as mine has much less than 1/4" of clearance, although it doesn't appear to touch when stationary.
