The 2.0 turbo ecotec is still being made, mated mostly behind automatics, in the regal, malibu, caddy ats, etc.... and Millions of the smaller 1.4 turbo ecos are in cruzes, sonics, veranos, etc.

Sorry, I guess I should have specified that most of my knowledge is of Gen I and II Ecotecs. The ones you're referring to are Gen III direct injected engines. Its not the same 2.0 turbo engine as the old one. The old one was RPO LNF, the new one is LTG. I don't know what all changed on the blocks from Gen II to III but I was never interested in messing with direct injection so I didn't really do any research on the new engines. To my knowledge all the Ecotecs currently on the trails are Gen I or II so that is why I concentrated the discussion on them.

Re:

The current autos are not 4t45e's either. They are 6t40 and 6t45e 6 speeds.

I build my single seat toyota. I still want to do this !!

I still want to do this... I want a ecotech to a powerglide or th350 to the most simple 4 to 1 case. no 2 wd or front burn needed , light and fast?

Since this thread was started I believe that Hughes has started stocking an adapter to the GM90* / V8 transmissions. It's not cheap though. And you also need a custom converter. All in I think you're around $1500 to get the TH350 running on the back of the Ecotec.

Ray Bates of Bates Engineering stocks the adapter to go to the GM60* bellhousing for a mere $250:

It's what I am using on my current build. There were a few 700R4's available with the 60* pattern. The lower first ratio in the r4 are probably better suited to the Ecotec anyway. The GM60* pattern will also mate the Jeep Wrangler 2.5L version of the TF904. That's a pretty bad-ass little transmission as well that mates directly to a D300. With both of these options the torque converter is custom.

Bates doesn't have a website. You have to call him: (714) 612-3639

BTW, I think it was Jesse Haines on Pirate, figured out how to shorten the TF904 to like 11" long front engine to t-case while retaining all the gears but losing park using all bolt-on parts.

It requred reworking the output shaft and a JHF adapter.

Short enough? 17.75" from the motor to the transfer case. The output shaft is at Branik getting resplined. The adapter is 2 pieces. The part that bolts to the trans is a 1/2" plate I made. The back half is a th400 to Atlas adapter. Sounds simple, but there are a handful of parts that need to be modified to make it all work.

That's awesome.

I figured that but he stated it like it's an off-the-shelf part.

Rokcrler · Apr 3, 2016

Its "off the shelf" from him... im in line for one... i think...

That adapter didn't look to complicated, esp if you had both pieces in the shop. If you have to get a custom converter anyway, the adapter wouldn't need to be the thinnest possible

It's a very simple adapter. I actually modeled it up in CAD and was about to have it machined before I found out that Bates was still in business and had them in stock. For me, by the time I bought the material and spent all the time cutting and fabbing it, $250 seemed cheap.

If you just line up the dowels using the TF904 on the Ecotec, the transmission ends up clocked about 7* IIRC. This adapter removes that clocking and makes it all flat again.

What about this requires a "custom" convertor? Couldn't one re-drill the flywheel and do something to take up the space of the bell housing adaptor?

Depends some on the converter you're using, but yes, you could do that. In my mind that would be a custom converter, but I guess it's really just a custom flex plate.
