Hey I got a quick question. What do you think about the trd tranny mount? Is it too stiff? I'm worried about additional vibration. I brought a new oem mount but its kinda soft. I can move it with my hand. Is the trd mount considerable stiffer? I don't want it too stiff.

O_O Absolutely amazing. Someday if I ever win the lotto, I'd like to swap a 6spd into mine with the V8.. Talk about perfection and using all new parts, I felt poor just looking at the parts list and prices you put up! There are so many things I'd like to do that you've already done. I'm sure it's gonna end up costing double what my car is worth.. LOL

I said the same thing about getting a 6 speed, but it should be the last tranny I buy. It is pricey tho. I brought 6 speed tunnel and some maintenance parts. Let me just say I could have brought a clutch setup for the r154. Lol. The v160 sounds like a tank when I'm shifting through the gears. Have you heard of anyone using a southbend clutch with the v160.

Small update.....
Anybody who has been around a Getrag car or got a ride in it knows how loud the transmission is. It is especially loud with a multi piece clutch. When I first did the Dynamat install over the tunnel, I thought for sure it would result in a noise free cabin. Although I am confident the Dynamat and the Cool-It heat/sound insulation did minimize the transmission noise, it wasn't as quite as I would have liked it.
I did some searching around on audio forums, and learned about a material called MLV, short for mass-loaded-vinyl. Whereas the Dynamat is a sound damper/absorber, the MLV is an actual acoustic barrier. It's the best material you can use to block noise out completely. I believe it is mainly a house sound deadening material, but it's been used within the automotive industry for a long time because it is so effective at reducing noise.
From what I have seen, it comes in two variations....
2lb/sq.ft 1/4" thick and 1lb/sq.ft 1/8" thick.
If you attempt to use MLV in your car, DO NOT get the 2lb. material. It is way too thick and impossible to work with. I first ordered a roll of the 2lb.... but it ended up being unusable for such a tight-fit area that is the transmission tunnel.
So I opted for the 1/8" MLV that is much more pleasant to work with.
I initially cut out a template and made all my measurement with a large piece of drafting paper. This was the most time consuming part of the project to get a perfect fit with as few cutouts as possible, because with the MLV you want no holes or seams at all unless absolutely necesarry. I basically just made some small holes for the airbag ecu bracket, two more openings for the side harness mounts, and four small holes to mount it to the shifter plate.
I am not one to exaggerate, but the difference between just the Dynamat/Coolit and now with the MLV is HUGE. Before the transmission and clutch noise was very noticeable in the cabin. If you were having a conversation in the car, it would be loud enough for you to notice. Now with the MLV , you can't hear the transmission at all. The clutch rattle noise seems extremely distant and not noticeable at all unless the car is standing still and you have the music off. All in all, I think this MLV stuff is the single best sound insulation material I have spent money on. The reduction in noise is a night and day difference....it feels like a Lexus again. Now it's loud on the outside, quite on the inside!

I wrapped MLV over the rear seat also a little while ago, just never posted any pics here. There is a company (Super Soundproofing Co.) that sells a wide variety of different MLV products. The one I used on the rear seat is 1/8" thick with a pressure sensitive adhesive.

found this thread while doing research on swapping a v160 into my auto mkiv and just had to say that your build was amazing. hopefully mine will be as clean as yours. keep up the good work.
