Hello I was wondering
first if you have compressor maps for the GTK-500 yet? I have been asking for them for over two years now and apparently your engineers are always working on them...

Second What wastegate would be best for this turbo Turbosmartl 38mm std flange or the TiAL 44mm MV-R?

This turbo is mated to a honda with a completely built engine consisting of

Dart tall deck block 84mm bore 87mm stroke 2.0L displacement
Crower stage 2 boost race cams & matching springs
Edelbrock Victor X manifold
GS-R Cylinder head
ARP head studs
Cometic head gasket
Ferrea stainless undercut valves
JE dished pistons 9.5:1
Turbonetics log style manifold ceramic coated along with downpipe.
68mm throttle body
5.967" eagle rods
ITR oil pump
Piston oil squirters
Zex Turbo nitrous kit 50HP shot
24X12X3 front mount bar and plate intercooler
MSD digital 6
MSD pro billett distributor module and coil
TiAL Q BOV
RC 750cc injectors
255lph in tank fuel pump
Adjustable fuel pressure regulator - 40psi
Fully balanced rotating assembly
9500+ Rpm redline

SPEC stage 3+ clutch
SFI lightweight flywheel
Canton oil pan
ATI harmonic balancer
Custom geared transmission with LSD
Traction bar system
adjustable suspension, struts springs alignment angles
urethane bushings
Hasport 95A engine mounts
Drag radials


Third When did the GTK series turbo stop coming with the aero head compressor nut?

Fourth what is the Max allowable EGT to run with this turbo

Is the use of anti-Lag acceptable or will it damage the turbine wheel?

What is the max reasonable boost pressure to run for this turbo?

My goal is to reach 500 HP

it ran 12.6s 112 MPH on 12PSI in the 1/4 mile on street tune

Thanks
J

1. No the compressor map for the GTK61 is not available
2. 500 HP I would recommend the Turbonetics RG-45.
3. No GT-K has ever shipped with the nut on it.
4. What EGTs are you looking to run? If it doesn't melt the manifold its not likely going to wreck the turbine.
5. Yes Anti-lag can be used
6. 25+ PSI is fine

* i had gtk550's and 1 38mm turbonetics w/g held the boost fine. ( combo was twin gtk550s on sbc, so we had 2.8 liters per turbo / wastegate. )

* you will hurt the engine before hurting the incol turbine where with temp...

*seen 35+ psi on the gtk's, the turbonetics thrust ball bearing is pretty good.
had 60+ psi on built sr20's , with turbonetics 78mm turbos..
