i have hunted, and hunted, and hunted, and cannot find the information i'm looking for. i am not wealthy and i do not have unlimited funds so to anyone who just says buy x kit that is $7k, kick rocks.

with that said. i would like to get a tr-6060 behind my 2j. before any send the thread off topic, the v160/161 will not be an option for me, r154 is also not going to be an option, and the ar5 is also out of the question.
i have been in the process of building this car for over 3 years and i have a power goal of 1200 and i want to have a manual transmission.

i have found two different sites that i can fall back onto if i can borrow money, but my overall goal is to figure out a way to get a tr6060 into the is300 for roughly 5k. i feel that is a feasible budget to do this

has anyone swapped this transmission. Grannas racing has done it, and sells a swap kit, but with the kit and clutch its right at $3900 before even sourchng the transmission:

here is the best deal i can find bolting it to the block with a good clutch
TOYOTA 1JZ AND 2JZ TO T56 FULL KIT - GM TREMEC T56 - Toyota 1jz-2jz - BELLHOUSINGS & ADAPTORS


i have found online a rebuilt magnum for roughly 1600 before shipping. i would just need to figure out the shifter scenario, and that is where i am stuck.


please please please if you know of or have seen, or can help with pictures on shifter placement please post pictures. i want to see all the different ways people have fit this into their cars.

i've been hardcore researching this for going on two months

Give Matt @ dedicated motorsports a call. He has this transmission and his shifter is dead center

Can learn a bunch just by looking at the pics. If this kit sets the shifter location properly you can then see what you'll need. Personally, I'd probably spend a bit extra for a kit like this to save the heartburn. Looks like they moved the shifter back 3-4" from where it's bolted to the tranny.


$ 8,095.00 - Looks like for the HP range you're looking at it's 8K.

Wonder if you can get them to sell you the kit without the tranny?

It looks to me that the shifter location is dead on with the Grannas kit. You can see the custom billet shifter in the pictures. Unless you know someone with or have a GM discount or buy used, his T56 deal is pretty damn good. I feel that the aluminum driveshaft is a bit on the pricey side if anything. I wish the kit offered a steel variant.

i've been back and forth with grannas, and they definitely have perfected the swap no doubt. the issue. i don't have the money to just outright buy it. you can buy his kit minus the trans, but its roughly $3900 if you get the entry level clutch setup with it.

like with the rest of my car its been lots of research and parts bought piece by piece

his kit is all inclusive which is worth the money, if i just had it laying around.
the rod shop, out of australia, also offers a kit, that includes a clutch rated for my power, for a total of $2700 shipped, which is everything from block to trans, just not the rear section with shifter, or trans mount(which is something that can easily be made at home)

i can get the transmission refurbed for roughly 1900, and drop it off to get beefed up guts put in for roughly another $1000,

so that puts me in right at $4700, then i have to tackle the shifter, the 1900 tr6060 has the tail shaft used on the camaro or mustand, which is different than the viper or out the box magnum. so the grannas shifter wouldn't work. i just can't merrit spending the extra 3k just to be able to use the shifter included in the kit.

You already have all of the information that you need to make you're decision. You say you're okay with spending $5k, but not $7k. You can piece together everything and maybe save $2-3k doing it. If you'd like to you'll have to figure out how to make it work. Personally I would think about what my time is worth and kinda go from there. Chances are I would just pay the extra few thousand and get a transmission that I know is good and bolt it in.

What are you going to do for a rear end for 1200 hp?

What ever came of this?

I'm in similar boat. The Grannas kit is worth the money. He's not charging a big markup on his parts. The entire arrangement is totally top notch and it's all totally figured out for you.

That said, it's still $8k. If it were a Supra that is intrinsically much more valuable, I could see it... But a T56 is simply not going to increase the value of our cars by more than a grand or so.

Anyway, on the topic of shifters:

The magnum has three shifter locations. If you look at the top of the trans, there are two plates. The forward one is square, the rear is rectangular. Both those cover potential shifter locations. The internal shift rail runs under both these covers and has 3 female sockets to receive the little ball-end of the shifter itself. The rear rectangular port/cover provides two shifter locations, usable by flipping the Tremec shifter so the lever is either towards the front or towards the rear.

Both the rear locations (rectangular port) are too far forward for IS300. We need a location ~4" further rearward than the rear-most magnum position.

The square port location up front is ideal for old pickup trucks.

It is also used by the TR6060 variants of the T56 magnum. If you check out the TR6060s, they all have a shift-rail housing bolted down to the square port location. That shift rail sticks out the back of the housing. All of the TR6060 variants have a divorced shifter that mounts to either the trans or the body of the car further rear - and have a shaft that communicates with the shift rail in the housing.

If you can fabricate brackets etc etc, You could buy the shift rail housing for a TR6060, and the stock shifter from a TR6060 car (2010-current Camaro, for example). Dissect the shifter for it's ball pivot, and fabricate a bracket to mount the shifter to the top of the trans. Then fabricate a shift rod that runs from the shifter to the shift rail in the forward housing.

Basically you are copying the arrangement of a 2010 camaro, just customizing the length of it to fit your own car.

Another thought is to buy a straight up TR6060 instead of the magnum. This will get you the shift-rail housing you already need as well as the shifter itself. However, it also gives you an integrated midplate + bellhousing you'll need to remove and replace with the a T56 midplate ($350). You'll also need to pull the oil pump out of the TR600, and your custom driveshaft will be ~$200 more expensive than a magnum driveshaft, because it will need a companion flange, CV joint and a telescoping feature - because the TR6060 doesn't use a slip yoke. Last, you will not have a gear ratio choice. TR6060's are used by OEM's for high power V8s, so they are usually the wide-ratio gears (2.97-.55). Our cars are probably better off with the close-ratio gearing (2.66-.65)
