1995 Grand Am 3100 Swap with 1999 3400?.

well the ones that ben sells fit right in there with 95 parts... tube egr, gaskets... and just the 2000 gasket too.

Currently in the process of trying to get him some more... TCE was supposed to do it but I think they are a little behind.

Well yeah it does fit, but my 94 which I'm sure is the same as 95, the bottom flange on the EGR tube is angled, so you gotta rotate that, and bend the tube back since the adapter and manifold is farther towards the firewall.

My design only gained me 1/2" difference compared to yours, and was impossible to cut by hand, and doesn't bolt up to a 3500 plenum since you can't put bolts from the back side of it like you can 3400/3100 large ports. The 3500 neck/IAC casting is in the way of that. I could of made it so you don't have to rotate the egr tube, but it would of made more cuts for me.

No harm done in bending the tube a bit to get it to slide in. I did use just holes instead of slots on the adapter for bolting it to the plenum. I used studs/threaded rods and nuts to do this. Works great.

I like how Brad is thanked in that guide about the EGR adapter, when infact the one pictured above the home made one was designed by ME!!! and he went and stole the idea and said Oh anyone can make this at home who would want to buy that from you....

Oh I still remember

My apologies. I will be sure to update my guide to reflect the proper creator of the plate.

Just curious if you are still making these? I would like to have a link or something to send orders your way. I'm sure the demand is still quite high for these. I wish I could remember who I bought mine from...

Well ben now has them on his store, I had been the supplier till just a month ago, My machinist always gets swamped so I told him to see if TCE could make them for him and they did. Plus with what I was selling them for to pay for the machine work it was third sale by the time ben sold it, and I hated to raise the price a lot so I barely made anything on these... probably like 20 bux on a run of 10.

As far as TCE goes I'm not very fond of their 4" bolt design but that was their call... I sent them my design and I guess they didnt like it.

Looks a little more blocky now but its polished up and has a TCE logo on it so there isn't much I can do.

Thanks for the update. I'll direct people to the 60V6 store now for their adapter purchases!

all GM salvage yard parts..

Oh wow, that's pretty neat.

Mind if I someday use those pics?

[3400-95-Modified]

Yeah you can also use 2.8/3.1 mounting plates and grind one hole closer and chop off the top third one... Works the same way.

The level of innovation here is great. I wouldn't be surprised if two people here came up with similar solutions on their own.
