Supra Tt Getrag Matted To A Rb30? Or T56

[LedZepLen]

I'm gonna live with my RB 20det with all the bolt ons and huge turbo but thats gonna be temporart till i have it made into a RB24 or i'll jut buy an Rb30 and put RB26 aluminum heads on it.

My goal is 600+ wheel hp and the full use od the 320km/h speedo i'm ordering. What i would really like to do is get a Supra TT Getrag 6sp or a Tremec T56 from the Corvette, GT500 and Viper matted to it. The one biggest flaw in any pre 99' skyline is the lack of annother gear. The car is just boring with 5 gears, i mean you are going a good clip in each gear it's just i'd like to cruise at more then 100-110 on the highway without incinerating all my fuel for a 120-140 travel speed and an extra gear and bigger turbo would correct this. Plus when i am hauling ass i'd like to hold the speed with a lower RPM and still have the option of down shifting once or twice and doing some really speeds.

Once i get the block and tranny i'll have arround 3/4 of a year to screw arround with it all to get working for the next summer as i'll be enjoying my car on a stock engine and 20PSI.

Has anyone used a Tremec T56 transmission or Getrag 6 from a supra in any of their RB applications, and what steps were taken to acheive this? RB's got the high rev capability but everyone else has the extra gear so i'd like to fill the gap and make my car into my vision of what a Skyline should be.

Much appreciated.

there are a few drift cars here using those boxes behind SR20"s and RB's so yeah it can be done.

Im also interested in this...specifically the Supra 'box.

From what i can tell, internally its the same Getrag unit as in the R34 GTR aswell as last generation M3 and M5 BMWs. But i doubt the housing is the same. So would prob need some mods/fabrication to make it fit.

They must not be the hardest things in the world to get installed if guys are putting them to SR's and RB drift cars. Plus if it can take a 2nd to 3rd upshift in the midst of a full throttle drift it much be durrable. I think the only reason they fail in R34's is that guys are doing full throttle 1000hp shifts with big wide sticky tires all arround to put thta power down where guys run 600-1000hp supras all day every day just fine because they have lack of tractioon to keep the shockload down a bit when doing a hard shift.

I'm sure once i have a block and the tranny sitting beside eachother i could figure out a way, i mean i'm a welder so it's almost expected that i half to make it fit one way or annother. Be it bellhousing modifying or a completely fabbed up one. If i completely fabbed up a good bellhousing i probably could sell a few in the process.

a guy in the usa just put down 1400 rwhp and 1000ftlbs of tq through a rebuilt v160.

the v160 is the same as the r34 getrag which as said earlier is also found in the supra.

the only difference is the transfer case shock loading the system on a gtr and the case design.
