what part of the driveline and what for ? gearbox being the weakest point

Yeh I was aware that the gearboxes are a weak point but I was just wondering how much ie diff's and cv's can cop before going bang.

Thinking of selling my GTST and going for a GTR with a full tilt 26/30(although my current set up is good) but was wondering if there were additional costs etc.

Im stuck in the position where I am rebuilding my motor and starting to think too much and its making my head hurt......

Do my full tilt motor and stick with my GTST ie then have to go strong auto or dogbox or rebuild to current spec and go buy a rolling 33 or 32 gtr and put my full tilt motor in that.......

and then I worry if the GTR driveline will take the power or are there other parts I need to purchase other than a dogbox......

Not a 16yo dreamer with a pipe dream either just a 32yr old big kid who loves cars......

The 25 and 26 gearboxes are exactly the same. As is the diff and shafts as far as strength is concerned.

How much hp are you chasing?

it all comes back to if you want to stick the the RWD platform or shift to 4WD

i prefer the rwd for the fun factor, it may not hook up the same, yet is fun and puts a smile on the dial

gtr all the way, pull the shaft on a gtr if ya want some rwd action, put the front shaft back in and realise just how much power you are missing out on in 2wd. I would never consider 2wd for the power you have unless your running slicks at drags or something. The box will need to be changed, thats the main problem, ive never had an issue with same power (high 500s at wheels) from any other driveline parts.

1000rwhp will put a smile on my face and would make it worth it for me as were crunching numbers and its not going to be cheap......

I love my GTST though as it's real perty.....so im torn

1000rwhp will not break a 25 gearbox. It will not break a 26 gearbox either....as long as it's new. It also depends on how you treat it. What usually happens is the synchros wear out, the further they wear, the more they move away from each other. The shifter clips in between them drop out and get munched in between the gears.

Sudden shock loading will also send them packing.

I would suggest a complete cryo treatment of the diff and gearbox, complete rebuild of the lot and you would be ok as long as you don't flat shift or slam gears.

If you want the extra security, get an OS Giken 6 speed sequential. They are only about $14k and are good for up to 1400hp

There are many cars out there with lots of power, but the biggest smiles on my dial were put there but what I achieved using the GTR's amazing driveline while launching and cornering.

I could not possibly recommend anything other then the almighty GTR.
