I did a very similar swap on my saturn (went from the m62 to a tvs 1320) and noticed huge gains in efficiency and lower iat2's.
Hummmm I looked up the one you said and all I found it on was for a V8 do you have any pics?

So placement of trans stayed the same. One key thing I did before I removed the old motor was made a jig that would tell me the placement of the trans as in height not front to back. This is pretty important as the motor with all the accessories get really close to the hood when closed. I don't have a body lift.

As you were, I was meaning the TVS 1900 although I'm sure the 2300 would be great for the 3800 if you were turning it in to a dragster. lol
As for the pics, I have pics of my m62 vs my TVS1320, but I don't have any personal ones of the 1900.

This thread is fantastic man. Now you've got me thinking of putting an LSJ in my 84 that needs a motor. I've owned an LSJ powered car for almost 10 years now and wrenched extensively on it. They're forged already and can handle in excess of 400hp with stock internals. (for the gen 2 lsj) and the gen3 LSJ is good for over 5, again, completely stock. Looks like I need to do tons of research and figure out the best means of doing either a 3800 or LSJ/LNF/LDK swap! Oh the possibilities!

Hell ya get to fabing, its all just nuts and bolts! I found 95% of the info for this swap from a guy named kiwipushrod on pirate4x4.com. I give him a lot of credit for doing all the grunt work as for what will work and not when it comes to the trans.

Ok back on track. So trans is finished and placed back in the truck with the jig you where suppose to have made before you remove the old motor so good height placement can some what be made.

If you can zoom in where the shackles are you can get an idea of the jig im talking about. Pretty simple, angle iron and shims.

You will have to remove the old motor mounts form the frame as they will not work. Find a motor mount (motor side) from the passenger side of a 01 3.8 fire chicken.

Now as for the rubber motor mounts what I used are 2 motor mounts from a 01 3.8 fire chicken. I don't remember what side but here is the part # duralast P# 2465 or A2465 or 108910, all of there # should pull that mount.

Ok so now is where you need to put your thinking cap on. Get some 1/4 plate and trace and cut out your motor mount out, 2 of them. (look back on the pic where just the trans is in and look at the motor mounts for an idea)

Drop your motor in for fitment Let the fun begin!

You only have one motor mount so WTF......This is where the fun starts. you will be pilling that 3.8 a couple times so be patient. Now that your 3.8 is hovering in there mate it to the bell housing. You will notice the steering box is in the way of the A/C compressor What I did was space the box off with 1/2 plate. (2, 1/4'' plate placed together )

Now you have the steering box spaced off, center your motor up and tack wield your passenger side motor mount plate to the frame. From what I under stand the motor mounts should sit @ a 45*, that how mine are. ( again look back on the pic with just the trans sitting in there )
