the gt4294r does make more top end power at max boost than t51r kai,
however hks did not take the 4294 and make it worse through R&D... that is to say i sure hope they didnt??
i havent tried a 4294 but ive heard the hks builds boost faster and stays in boost longer between gear changes.
a quality i am definitely down with on a 6 speed supra.
its also typicaly regarded as a very responsive turbo once your in boost and aswell the power curve is quite linear so that the power comes on stealthly which can be misleading and it also saves you money on tire shredding torque curves
i would be in heaven if i could get a divided back housing for the t51r and throw a sound performance quickspool valve on it

From what I've heard, the TiAl/HKS style single entry flows "better" than standard single or divided entry manifolds, but it just doesn't make use of the strong exhaust pulse of a 2-rotor. Take it FWIW though, since nobody's shown any real evidence that either is better for spool or top end on any engine.

I LOVE THE power the gt42 makes. However the sound of the hkst51 has no comparison to the gt42
thats my opinion after owning both turbos

You may be a seller of turbos, but you cant make sweeping statements like that, unless you have owned/built high powered rotaries and have run both types of turbos.
People like to see evidendence on real world experiance and results, not theory
In regards to housings, why have TIAL made a rear housing to replace the divided housings on GT42 which is using the same design as the HKS T62/T51Turbos? I guess TIAL and HKS dont know what they are doing

The only reason the 51R sounds the way it does is the surge cover, put the same style surge cover on the 42R and you'll have the same sound.

i am scratching my head on this thread...
"to generate around 450whp?" OP
i think it would be good if the OPer clearly stated his objectives HPwise... if i read his statement (above) all of this HKS/GT42 stuff is totally inappropriate.
if you are looking to make 450 the thread should be comparing the GT3582r, GT3574, Borg Warner R85, S300-61, Tech 300.
OP, what are you after? unless you are after 600+ hp the T51/GT42 isn't for you.

HKS T51 SPL 474hp @ 18lbs (tunning on 93 with the ignition system from rx7.com)
GT4202R 534hp @ 20lbs (no tunning just 1 dyno run on E85 ignition system from microtech)
HKS spooled @ 4700 with full boost @ 5200
GT4202R spooled @ 3700rpm with full boost @ 4200rpm (thats with a 4 inch downpipe fitted to a 3in exhaust).
dont forget the intake i have on the gt42 so that might make a difference
both on street ports.
p.s. the gt42 has a 1.28 rear housing
