I thought this may be useful to some folks looking to build a ka-t setup. Seems there aren't a ton of detailed posts with dyno information. I believe when done right these engines have great potential. This engine took some serious abuse this drift season(Apparently I am the 4th owner of this engine since built as well). 10/10 I would recommend anyone going the ka-t route. Anyways on to the details.

1992 ka24de

-Stock cams and valve assembly
-BC rods and BC 9:1 pistons
-Stock Intake manifold
-CX racing top mount t3/t4 manifold
-TIAL MVR Wastegate
-Precision 5431 Turbo .63AR

Drivetrain

-SPEC stage 3 6 puck sprung clutch
-ACT Lightened flywheel
-Stock driveshaft and axles
-Welded Diff

Fuel

-Walbro 255
-1000cc top feed injectors
-Aeromotive FPR

ECU/Ignition

-ECU Master EMU
-Modified trigger wheel (to delete distributor)
-CBR 600 Coils
-Haltech Igniter

This particular set-up made 326whp @14psi on a roller dyno. With very conservative AFRs. On 93 octane pump gas.

As you can see below the power fell off pretty hard at 5500 rpm. I attribute this to the turbo being slightly too small. The intake manifold could have also been restricting airflow. (Please add your thoughts below)

This was a pretty affordable route in my opinion. I will be upgrading the turbo to HX35 this winter. I'll update with a dyno chart and let you guys know what happens.
