It is possible and if the engine is built right it will hack that all day long, the problem is as will all know 4x4 transmission, anything over 300 bhp mark imo won't take long for a standard box to shit its pants

launching the car with a proper 400hp you will need at the least a Good clutch, Quaife rear diff and a front diff plate and then i would say you may still break somthing continuly launching it

you could get cts to shotpeen and superfinish the gearbox gears which
dosent make them stronger but lasts longer and costs about £300
also change the rear diff to a 2wd one as its 7.5" rather than the
awds 7" for more strength and OR
if you want to do some diy you could try a stock skyline box with
adapter plate, custom flywheel and the max that has been run on these
is 700 awhp so 400 will be ok
if you want to go this route ttvracing has made custom flywheels for
the zetec boys on here and i would speak to cts again about the
adaptor plate etc to allow it to bolt up to the yb as you really need to get
that right or things will keep breaking as not aligned etc.
check out http://fordpower.org.uk and search for skyline and click the
skyline box thread as it has lots of info and the ratios are similar
Skyline boxes go from about £500 for the 5 speeds and about £1000
for the 6 speeds that only come in the r34s but barring the 6 speeds
the late r33 gearboxes are the strongest
OR you can get a mullit box
