TREMEC T56 Magnum-F vs Regular magnum - installation in existing GR700 supra

Tremec Magnum-F vs T56 Magnum

My good friend and customer Ryan Scott recently upgraded his GR700 kit to the new Magnum-F transmission. I asked him to highlight the difference in shift experience/feel between the old kits with the Sikky shifter and the new Magnum-F kit I offer. I think the results speak for themselves!

I also asked him to demo the new bluetooth transmission harness product I offer which allows control of the reverse lockout based on speed, and also converts the transmission speedo sensor signal to work with the factory dash/speedometer. All in one nice clean harness which is as close to plug-and-play as possible. All of it controllable and customizable through a smartphone app. This replaces the old way of doing it with the pigtail kit and the SGI-5E or SGI-100BT box.

Here is the video below from Pure Function on youtube.


If you have a current Grannas Racing kit and want to upgrade, there are a few things you will need to change in addition to the transmission:

  1. The Magnum-F Transmission
  2. Driveshaft (magnum-F requires a longer driveshaft)
  3. Shifter (my new magnum-F shifter)
  4. If you are an original automatic MKIV, and used my tunnel cover product, you will need my new magnum-F version tunnel cover. The magnum-F requires a little more trimming and a slightly larger cover.

Contact us if you are interested in a kit, or interested in upgrading! I offer special pricing to return customers!

13B and 20B Rotary T56 Magnum swap kits for the FD3S - Updates

After test fitting a Tremec Magnum-F, along with some other R&D on the FD3S rotary chassis, I have updated my current rotary T56 Magnum kits to now only use the manual version bellhousing going forward.

The manual version bellhousing uses an FC3S starter, which mounts rearward towards the transmission. This setup works better for all applications and makes it simpler to manage on my end. This also was done out of necessity, due to the most 20B swaps engine mounts not allowing the automatic starter to fit at all.

The manual version bellhousing will fit both an auto rear plate or manual rear plate, so it only makes sense to do one kit.

The only downside to this style kit is the fact I have to take extra time to machine the magnum trans case to be able to fit the starter. This adds some extra labor costs, but in the end you end up with a beautiful bolt-in kit. See the pictures below showing where I machine the magnum case.

Here is a video of the installed transmission:


The only bad news, is during this recent R&D I found that the new Magnum-F transmission does not fit well in the FD3S chassis behind the rotary motor. Unfortunately, even though the magnum-F shifter is further back, it still does not sit back far enough, and you would have to cut your tunnel at the front of the shifter hole to clear (see pic below of me trying to test fit a Magnum-F in the FD3S).

The downside to this is an extension shifter will still be required. There is no sense in paying the extra money for a Magnum-F, and then still pay for and have to run an extension shifter on top of that. It is cheaper to run the regular magnum and billet relocation shifter setup (Sikky).

Orange car comes back out swinging at FL2K

The Grannas Racing "Project H-Pattern" aka "Orange Man Bad" Supra came to play at TX2K with the goal of getting the car to leave the line more consistently. This consisted of adding a "long style" clutch to the mix. This is basically an adjustable clutch which allows you to adjust the weight and pressure on the clutch to allow it to slip on the line. I enlisted the help of Cale Aronson, a former Pro-Stock racer who now runs Black Magic clutches. Cale helped setup a new prototype 2JZ long-style clutch for this car as well as help dial it in at the event. 

The plan was to use FL2K as a test session to get the car short tracking and dialed in for World Cup Finals - Import vs Domestic the end of October. Thanks to Chris Delgado's tuning and Cale's clutch knowledge after only 4 passes we got a new personal best of 1.21 sixty foot and a 5.0 eighth mile... And what is really crazy is, on that 5.0 1/8 mile it broke the suspension on the launch and i was dragging the drivers rear tire in the wheel well down to through 3rd gear. If you watch the video below you can see how the car was swaying up top due to pretty much no control over the drivers rear wheel. On the next pass the clutch was slipping hard up top, and we ended up not being able to get it done on both ends of the track, and ended up getting knocked out first round of eliminations.

I have always struggled with getting this car to leave, so now that we have that straightened out, I have really high expectations going forward. Can't wait to see what the car will do at WCF! See you there!

Grannas T56 Magnum GROUP BUY 2019 has started!

The 2019 Grannas Racing T56 Magnum transmission group buy has started, and this year it is featuring the new Tremec T56 Magnum-F. This puts the shifter in a more ideal location for almost all my swap kits (other than MK3 and rotary powered FD3S rx7's)

This means NO MORE RELOCATION SHIFTERS! Smoother shifting, and no additional shifter to purchase. This means my kit prices have DROPPED! So that is great for everyone!

Here is the link to the group buy page, any questions please contact me.

In the video below at about 4 minutes I show the magnum-F in my supra and show the shifter feel!

The White Monster 6-Speed Supra Returns - Rebuild Part 1 - Motor & Suspension

I did a video documenting the first part of the rebuild on the white Supra. I also included some video of some of my favorite passes at the beginning to build a little hype and a little inspiration for myself to get this thing ready.

Grannas Racing 3.4L Stroker 2JZ-GTE

In part one, I will be covering the assembly of the motor, cam install, and suspension install. The motor was built by Brian Roche Racing Engines, and consists of an Eagle 3.4 2JZ crank, Callies rods, and diamond pistons. The block is 3/4 filled with epoxy, which retains streetability as well as adds strength to the casting.

The suspension consists of my Ultimate IRS stock replacement chromoly tubular subframe, my adjustable lower control arm setup with eyelet shock mounts, strange double adjustable coilovers, bucks performance upper adjustable arms, and figs performance adjustable trac arms and figs toe arms. The rear end is a Driveshaft shop 9" setup.

MKV Manual transmission option coming soon!!?

I really think the MKV is going to have a manual option soon, direct from Toyota/BMW. While doing R&D on a T56 Swap kit (T56 Magnum) for the MKV Supra, see what I found that makes me believe a manual is coming in the below video! Don't forget to subscribe to my channel for future updates, and other Supra related content!


Also in this short video I install a Titan Motorsports downpipe and Protune piggyback ECU on my wife's MKV Supra Launch Edition. These two parts are super easy to install and add about 100WHP for less than $900. You can not beat that in bang for buck. These cars respond really well to light mods, and I wanted to give her a little more power to play with.

T56 Magnum 6-speed manual transmission swap for the MKV Supra

I think everyone knows me and the whole "not my supra" rants. You know I can not stand the fact that Toyota subcontracted out the iconic Supra name to be built based off a BMW Z4 chassis. Come on Toyota, do you really think a Z4 is the Supra equivalent!!?? 

T56 Magnum Swap Toyota Supra MKV Tremec Grannas Racing 6-speed Manual

Well, whatever! The deed is done, Toyota settled and now we have to settle (or move on - and I don't blame those that do!)... but it is too ironic that my wife actually loves these cars. I guess it is like they say "opposites attract"!

So... I figured what better way to make her happy and allow me to get closer to the enemy than buy one in the hopes of putting a man pedal in the car. The goal is to build a GR-Series 6-speed transmission kits for the car. Just like all the other chassis I offer swaps for the kit will be based on the Tremec T56 Magnum transmission, which is King of the street 6-speed boxes. Here's to hoping it is possible, as this is more difficult than most other cars, as the MKV is not offered from the factory as a manual transmission. So there is no bolt in clutch pedal option, no bellhousing option, and uncharted territory when it comes to the engine controls and electronics. It is a little bit daunting but I am hopeful this will come to fruition quickly!

Here is a video review from a MKIV aficionado and MKV pessimist.
