ISR Performance Turbo Upgrade Package - Nissan KA24DE 91-98

5 Star Rating

Buy in bulk and save


Finally an Inexpensive KAT kit! The Nissan KA has become a wildly popular engine for turbo upgrades. This is due to the engine’s heavy duty iron blocks and 600cc cylinder size, which provides robust torque. Plus, the KA is a lower-priced engine. With the Nissan 240sx KA24DE turbo kit, you’ll get a dramatic boost in engine power without having to break the bank.

Special Notes

Please note that this kit is not 100% complete. You will still need to get your oil feed and drain lines taken care of. We do not have a line kit for the KA as of yet.

When doing a bottom-mount KAT, the downpipe will be very close to the floor board. You can either clearance the downpipe and floor board, or purchase Xcessive KA lowering brackets. This Nissan 240sx KA24DE turbo kit does not come with a blow off valve flange; please call if you would like to have one added.

Kit Includes:

  • ISR Performance RS3871 Turbo (rated to ~380hp) (requires tuning, injectors, maf, etc)
  • ISR Performance V2 KA24DE Bottom Mount Turbo Manifold
  • ISR Performance Turbine O2 Housing
  • ISR Performance Downpipe
  • ISR Performance Intake Kit
  • ISR Performance KA-T Front Mount Intercooler Kit

Don’t forget your Z32 MAF, Injectors, and Rom Tune.

  1. Great starter turbo setup

    Posted by Unknown on

    Great Kit to slap on a stock KA engine for the price, running 8psi on stock internals. great setup for a conservative street tune.

  2. Best setup for cheap ka-t

    Everything fit perfect minus the downpipe that is easily modified. stock internal 145k mile ka 550cc injectors n62 maf 10lbs made 262hp 248tq

  3. Best starter setup

    Posted by Cheeno on

    I've had the setup now for over a year... 17lbs with 550cc inj. z32 maf. walbro 255 enthalpytune safc . Made 279.7 whp on 93 octane mustang dyno. Eagle rods cp pistons . I had 8lbs on my stock internals and it was snappy then! Definitely a 5 star starter setup!

  4. Great Inexpensive KA-t setup

    Can't beat this setup for the money. The turbo manifold fits great, good quality construction, and colors nicely from heat. Turbo is strong and maintains boost all the way to redline. I've had mine for almost 2 years - driven the car across the country, drifted, and daily drove the setup. With injectors, Z32 MAF, AEM EMS, and a 255 Fuel Pump - my setup made 245hp/231lb/ft tq. @ 9lbs on 91 octane. I have full boost at 4k rpm. I would highly recommend this setup - especially if you have stock internals in your KA. Makes for a fun ka-t setup!

  5. LEGIT.!
