Interesting. It would appear that all my 4D68T's, do in fact, have the EVO pattern. Craptastic.

Only saving grace would be that I could drill the "5th" hole location on a 2g trans to allow the alignment dowel in the 4D68T to mate up.

So, would you have any intersest in making a adapter/spacer to ...

So, here's a good question regarding the dsm/evo 1-3 vs evo 4-9 pattern. How well does the 2g dsm pattern line up with the evo 4-9? They look similiar but the alignment dowel is different.


My prediciment is I have several 4d68T engines. Sadly at the time when I bought them, I didn't realize they ...

While you're at it, incorporate the BOP (Buick,Olds,Pontiac) bolt pattern.

No, Bill. It's not a 2nd gen DSM pattern. Remember you can bolt together a 2nd gen and 1st gen 4g63. The locating dowels are lower bolt locations. The second pic shows a 1st gen backing plate on it for reference. The holes on the left side, the second hole up is doweled. The pattern is different ...

My internet is insanely slow today (love dial-up!!) so, I didn't visit the earlier posts and I don't recall the earlier discussion.

So, what pattern is this? EVO4-later? Did the EVO line change? Like 4-8 is one pattern, and EVO9 is another?

Story, I've bought 4-5 Mitsubishi diesels. They are all ...

If if was me, I'd go FWD. That car is going to be crazy unstable with that short a wheelbase and 300hp in RWD form.

Gen II adapter should include the BOP bolt pattern. (Buick, Olds, Pontiac).

Love to buy one or two of these, but I've got a BOP transmissions.

My question would be then when you buy a converter, they are listed for a both a th350 and th400, are the mounting pads set up to where they would have to be shimmed when using the th350?

From GM's prospective, no. The adapter should be the same, in the same location, regardless if it's a turbo ...

Thank you for the information.


I don't know what else to say other than GM's spec is different. From the company that built/designed the trans.

you know ?
I went through all the crap of trying to find a metric numbers for everything on the GM trans, yeah, they list metric numbers, but all they did was take existing US standard demensions and converted them to Metric ( broken) numbers IE 1/2 becomes 12.70 mm , the factory never retooled or ...

the TH 400 is a bit different from the rest of the GM transmissions, from what I can tell, the 400 needs 3/16 in free travel end play and the rest only need 1/8
I put enough material in the adaptors to build them either way , but I need to know what you have before I cut it

As I said before in ...

Any interest in including BOP and 3.0L pattern on it also?

To account for wideblock/narrow block, why not put some extra material (width) on the locating dowel bosses? Then you could drill for either setup.

Hey Morpheus,
Now looking at the depth of the slots on the converter 'neck' (that goes into the pump) has to be deeper than the pump 'fingers' that go in them, how much of the pump 'fingers' are actually in the slots after the pull up?

It's amazing how all power is being transfered to two little 5 ...

this number has no value to me because it assumes that the crankshaft in the Mits engine extends exactly the same length out of the rear of the block as the small block Chevy does
the combination of the engine adaptor plate coupled with the crankshaft coupler had to be reasoned out in both metric ...

OHHHHHHH! JEEEEEEEEEEEEZUZZZZZZ I forgot all about ' convertor pull up' I feel like such a dope!

I have dial up so, I can't see the vid. Not sure why all the sarcasm. It was a legitimate question. I know you didn't forget about it, as you ...

your in Toledo?

Directed at me?

If so, no. I'm now located in Pontiac (was Ypsilianti).

What do you have for converter pull up? Distance from converter face (engine side) to crank adapter. This is with the convertor fully pressed into the pump on the trans. Can be critical to ensure life of ...

Wow. Been a while since I've been here and look what I missed!!

Go back 4 years ago, I was looking at building an adapter and had drawn up in Solidworks, this exact scenario. I always wondered why Buschur hadn't gone this route, because it was so much simpler and lower cost. I simply never had ...
