This week Mike takes a look at the often overlooked Nissan KA24DE engine and shows us why it may deserve a second look before tossing it in the trash and building an SR20!

Funny thing – KA24, E or DE, are one of the class standbys in SCCA GT-3 still. Going by in-car, they’re stretching a smidge over 8k RPM but not sure what lifespan is like doing that. I think around 260-280 at the flywheel these days, NA, through a restrictor.
Needs a billet crank and a refresh every 6 hours or so.
Still seems like it must be cheaper than trying to get a 4AG up to those power levels; the performance levels of the class have shifted upwards over the last decade or two.
That’s crazy how it’s some trickle down Austin technology. Great history Mike!
Very trickled but still a distant relative.
Hi Mike! I’m beginning to piece together a turbo kit for my ka24de. The engine was recently refreshed with stock internals and hope to get around 300 to the crank. I am planning to go the route of the Tomei M7960 bolt on kit. I was wondering if you had any experience with or know much about the kit? Thank you for your time and I hope to hear back soon.
Best regards,
Matt
I’m on the same boat, I too would like to know if MotoIQ would be able to rebuild my KA to accommodate the Tomei Arms M7960 turbo kit. Looking forward to MotoIQ reply 👍🏽
I guess I stumbled across this because I just got a 04 Nis Frontier and it has a 4cycl with M/T…. It’s got 300k miles lol…. Do I have a ka24de ? Online everything looks the same as far as compression ratio and h/p#s and besides air intake……. Just really want to know … Plz… Thanks .
How much does a rebuild like this normally cost for a KA24E?
