only $90 for the kit, i find it amazing how some people want like $1500 for it lol

[XofXtimeX]

Well not exactly 1500, but close...800 to 1200 depending on how much work you have Hinson do for you and you do your self. The difference is you're getting soft mounts as well which is nicer for daily driving the car if you don't plan to just run it at the strip.

[tl1000sga]

Thanks Chris, those pics helped out a lot. I think I'll go a similar route since I don't want to mess with the suspension.

What are you planning for the exhaust? Don't want duals, but worried about clearance if I have to have a crossover pipe.

[Shift_Kouki]

Do the guys wanting $1500 still require the same sort of welding to get things fitting right?

If so, yeah... its amazing what people want for that.

That is a universal kit...it WILL have to be modified to work. But, yes it's a far cry from $800+ .

Are you sure about that? I was under the impression that the Hinson mounts were pretty much solid.

Mine have the round poly bushing and I also used a 60A Durometer hardness 1/4" square of polyurethane between the mount and subframe so it's not completely solid.

I'm using an Apex'i GT Spec Exhaust and running a Stainless 3" Y pipe to connect the headers into it. I haven't really got under there to look at what is going to be necessary, but I think it'll work out. Might have to buy some Oval tubing from Burns, but I hope not. For the crossover to clear the transmission, I might have to cut the GT spec back to the resonator, but time will tell. I'll post up pics when I'm finished.

[XofXtimeX]

Just a quick question though.

You people using the 90 dollar mounts. What are you doing for transmission mounts?

[cnichols]

Making our own of course...



It's finished now and bolted in...I'll get more pics by the weekend. Notice there is a gap on the one side. I just got the aluminum spacers made, so I will take pics of everything.

Cost for the Transmission Crossmember = $0Cost of the polyurethane "mount" = $0 (leftover from engine mounts)Cost of new 10.9 bolts = ~$8

It's what I was under the impression of why it wuld even be ok to be worth 800. If not good lord lol.

I like your idea though me and my friends were thinking of some kind of polyurethane style to make it not a complete hard mount and you just helped me on that thanks.

Where exactly is that metal from that you used for the transmission mounts?

[NotDave]

cnichols your posts are very informative

i just wanted to say good job

[nani]

is that the finished transmission mount? looks like aluminum cnc? if could you share the dimensions, i think i can do the same thing at work. let me know tahnks?

[cnichols]

Yes, it's from a 3/8" thick piece of aluminum that I had CNC'd. You may not want to use my dimensions as your engine may end up in a different spot than mine. It's probably best to start with the crossmember and go from there. I could have gone back a little farther (towards the firewall), but wanted room to get behind the intake as the MAP sensor, knock sensor, and oil pressure sensor are all on the rear of the block. Also, my entire engine harness comes through the firewall behind the passenger side head, so I needed access to it.

I will post up the dimensions when I get some time (this week/weekend) for those that feel my way is the way to go.

Hey Chris -

It's awesome having you back on board.

[cnichols]

Hey Chris - It's awesome having you back on board.

Thanks! It's a shame I was "gone" for so long, but after the move to a new city where I knew nobody, buying a fixer-upper house, traveling for work, and being a slave to this project, I'm finally slowing down enough to get back on here.

I'm hoping to bring it to Carlisle, but we'll see.

[AZhitman]

Anything I can do to help, lemme know.

We *might* hit STL this year.

[mmm240]

great info!i do hope you will work closely with hitman and his new sites!

[Shift_Kouki]

Ahh, time for me to get to work on that now that some exams are out of my way.

Hopefully it will mesh well with whats already there, and be useful to people looking into the V8 swaps on 240's

[Blown240sx]

Little Model of what I plan to make my mounts like. Almost the same as Chris's except I want to the lower brace to add a little more support with some 1//4 inch steal plate.

[bone_stock_240]

Is that solidworks or unigraphics? I loooooooove that stuff.

[Blown240sx]

Solid Works

[300hp owen]

I'm a little worried about you running that flat plate for a transmission mount as it is likely to bend and fail from fatigue, especially since its aluminum and only from flat stock... you should reinforce it vertically at some point I would think.

good luck on the swap it looks like its coming along very well, great progress man, good stuff!

I'm curious to see how everyone runs their exhaust with these setups and what transmission mount setups provide the best clearance for exhaust routing.

[Blown240sx]

Could someone supply me with the measure ments on the transmission mount I should be able to draw something up that will work. I also need an idea of how the transmission mount looks.

[cnichols]

Like I said in an earlier thread, there are so many ways to go about it, there are no measurements that are "right".

Here is the best transmission mount I've seen. It beats the pants off mine. Like Owen said, mine might fatigue/twist after awhile and is something I've kept in mind. I will get to it at some point...hopefully sooner than later. I have one just like it made out of stainless steel, but it's so effin heavy I don't want to use it, so I'll probably just weld some support to that one.

Mine do have a lower brace made out of 1/4 steel.

That's from ls1tech, right? I saw that and *drool*.

[mmm240]

ya'll got me excited!!!

[Blown240sx]

I kinda figured it was but it looks like the same brace setup the RB mounts use I figured if you placed the brace out futher ont he mount it would supply more forward upward support.

[cnichols]

It is further out. Instead of what you did to get it back to the subframe, I just used a steel spacer and a slightly longer bolt to keep the support bracket simple.

[WDRacing]

My brother in law owns a machine shop in NY. If we had measurements I can probably setup a really decent group buy. I've seen his work, he can do anything. They are a big company though, so it would have to be a decent sized order. But between Nico and everywhere else, we may have enough interest. We could even slot the brackets to accomodate motor placement...

Any thoughts?

WD

[XofXtimeX]

I think it's a great Idea. Although I think with so many people doing the swap...It's not somthign they plan to do soon or more then likely won't go in on a group buy on somthing like this depending on there time frame. How big of a demand are we talking needed to be able to duplicate mounts?

[Blown240sx]

Ive thought about mass producing mounts once i get my drawings to scale. If they bolt right up after I get the measurments down Ill have some copies made and sell them probably.
