Hello, i have been searching for gearboxes for a while now and i cant really make up my mind.

The car will be street driven so the gearbox must have a reverse and be able to downshift by itself etc.

Seen some people using powerglide t400 / t700 and liberty gearboxes etc, but the liberty gearbox (clutchless) seem to be pain in the ass for roaduse?

anyony got any suggestions here? the gearbox must hold for atleast 1200 bhp

 

Best regards

Nice street car with 1200hp.. Powerglide or th400 are your only choices really.. Mate owns a 1000hp GTR and commented on the sequential being a little rough for a streeter. 

Really depends on the type of racing you plan on.. auto would be bit average for circuit, holinger would be ok for drags. mentioning liberty leads me to believe its a street drag car?

unsure what you mean by a little rough, although I am only around the 800whp mark, I find the holinger perfectly streetable, obviously using the clutch as cruising around for daily driving.

Wow, First you wanted an OS giken or PPG synchro gearset, and now you're talking Autos ? WTF ? That's a pretty dramatic difference between setups. If you go the auto route it is basically a "street registered" drag car. C'mon if it's got an auto in a BNR32/BCNR33/BNR34 to me it is hardly a GTR anymore.....

At least the sequential dog boxes have a certain amount of "having your cake and eating it too", as they can be streeted, can be circuited and can be drag raced all with good results. I really hate the idea of an automatic GTR.

Anyway CRD have done TH400 on GTR like JUN II with 4WD so it is possible.

I think CRD and Maatouks can both supply a TH400 and the necessary gear to install the box. 

 

the actual set up of it is the tricky bit, I would only go auto if it was going to be setup by one of the guys who have runs on the board to make it all work.

Just the usual multiplate clutch with laggy RB "roughness".. more so in comparison to an auto. Setting it up would be alittle tricky although it looks like some shops just manage to buy a combo from Als raceglides and with afew converter tweaks its running 7s/8s haha

I would suspect those guys who setup and run 7s and 8s have been playing and tweaking with converters for years. I would be cautious of thinking a newbie could replicate.

      Manual Shifter slightly bounces/moves/vibrates when accelerating/deaccelerating

      By Doug 98 R34 GTT · Posted

      New R34 owned here (from the US) and found a gem, '98 GTT with ~6k miles, super clean & completely stock. When shifting there's no grinding, shifts smooth, etc. The concern I have are 2 things: 1) Only in 2nd and 3rd... when maintaining a slower speed (in traffic as an example) as I let off/on the gas, the shifter will slightly move and vibrate. If the clutch is engaged, none of this happens. It's not bad, but enough to feel like something isn't necessarily right. 2) This mainly happen in 4th or 5th... the shifter slightly bounces up and down, almost like it's riding on unbalanced tires (and I do think the tires are unbalanced as I get a little of that bounce feel at higher speeds, which is maybe why it only happens in 4th/5th). Lastly, and sorry for this noob question but I want to work on this car myself, can someone teach me some on these manual transmissions? Like servicing them, best products to use, etc.; would be greatly appreciated. Thanks!!

      Coilovers aren't even the first step. Bushes, subframe position and alignment, HICAS elimination, adjustable upper arms and traction arms in order to dial out understeer. All these things need/deserve attention first. ARBs (There's no such thing as a swaybar. Please, everybody, stop calling them that) are useful if you want to limit spring stiffness. Otherwise you can control body roll with springs. Spring and damper rates are a function of road surface, speed and usage. There is no solution that works for all cases.

      Define "nothing". Is the starter spinning but not the engine? Engine turning but not firing? If the engine is turning but not firing, then you are missing either fuel or spark. You need to find whichever has gone missing.

      Shitbox Tiguan updates, got the APR OTS tune put back on (no charge for it to be removed/added back), didn't want to just come in just for that (not a fan of wasting people's time for nothing) so I purchased an APR dog bone insert. The boys at German Performance Garage said they would fit it for free too since they had 1x hoist free. Now that's service you don't normally get from most workshops. Anyhow, tune back on, snow grate pulled out, dog bone insert back in and not going to lie, a few smiles when I nailed it around the industrial area heading back onto the M7. Amayama also said 1 to 2.5 month wait for the RB25DE heater hose, yeah why not, car has been off the road for nearly 3, what's a other 2.5?

      Hmm I'm going to approach this from the other side... What is the car doing that you don't like or what would you like the car to do that is currently isn't doing (handling wise that is)
