I'm not having much luck in the retro forum on here but I do have a question about the EA81T powersteering setup. I know its like an EA82 setup but I noticed the bracket that bolts to the top of the block has 3 bolts in it, just like the EA82. Now I'm putting an EA81 NA into an EA82 coupe that has powersteering. I was wondering would it be possible to bolt the EA81T powersteering bracket to the EA81NA block? The EA81 block I saw only has 2 bolt holes which look to be the holes for the alternator bracket.

I don't think it would be possible unless you had a turbo block. I uploaded a pair of pics of the two engines to my album. The longblock is the EA81T and the half block is the EA81.

well drat... I do believe I can get the bracket and stuff from the EA81T but I got a fully resealed EA81 NA that was going to find a new home into my coupe. Looks like its time to rethink and reengineer the EA81 a little. New brackets for the alt are looking to be the only way and possibly a redesigned powersteering pump...

Why couldn't you use the EA81 power steering pump and the EA81 hoses?

Because the block doesn't have the mounting holes as the EA81T.... It's all the same though between the EA82 and EA81T... At least as far as I know..

I think that a later ea81 block will have space to tap the holes for the power steering bracket, but I'm not sure about hooking up the alternator and everything because the bracket incoroporates the a/c pump as well.

If I remember he's using an 81-82 solid lifter motor, so thats gonna be a no go on the power steering stuff on the block.

I wasn't talking about using the EA81T stuff... I mean to use the EA81 non turbo stuff... or is that not gonna work at all?

no it won't because the nonturbo EA81 stuff is VERY hard to come by in a decent condition. I actually have thought about using the hydrolifter EA81 I have in my garage instead (woo extra set of gaskets FTW!) since it has the bosses for the EA81T powersteering bracket, just need to be drilled and tapped. I also have a helicoil kit, lucky me;)

I used an ea82 power steering pump on my turbo Brat. it bolted to the bracket just fine. the fittings were different though.

yeah thats where I saw the use of it;) I'm just going to use the hydrolifter EA81 I have and drilland helicoil the holes so I can mount the PS bracket to it...
