Car: Aussie Delivered Nissan 200SX

Post

I am thinking of doing a big HP ka24de engine swap in to My 200sx. In Australia we only get the ka engine out of Nissan Navaras and these engines are extreamly expensive. I think it will be cheaper to import an engine from the states. Which brings me to the cruxs of this topic, which ka is the toughest, or are they all the same. I am sure that nissan have changed sumthings from model to model. No one in Australia has done anything with the ka yet so this will prob be the first big HP Ka down under if any one has sum helpfull info I will certianly listen. Mark

I'd be really surprised to learn Nissan changed materials or casting processes between the S-chassis years of KADE's. 1991's did have slightly higher lift cams though.

If I were KA-T'ing I wouldn't go without new rods/bearings/hone/rings and a thicker heavier duty head gasket to lower the compression a little. something just wouldn't sit right with me if someone told me i could run 250whp on a 130k+ mile old motor for more than a month without a rebuild.

If I were to do a KA project, it would definitely be N/A. there's a shop around here that makes artwork out of cam regrinds for hundreds less than aftermarket cams would cost... open up the head a good amount, add KA-E (higher compression) pistons, SR injectors & a little tuning, obviously header & 2.5" exhaust... that would be hardly butt-dyno decipherable in power difference as a stock SR with no lag and gobs of on-demand torque.

I vaguely recall a thread many moons ago regarding the Japanese and swapping out their SR's for KA's, something about how americans go ape**** over SR's cuz theyre the cool thing to do and how the Japanese go ape**** over KA's because they're a superior choice for some popular form of racing over there

Actually NISTECH said that there was no difference in the cams of the 91- 93 KA's at least. Dont know about 94, I know the S14 cams were a little more conservative. I think the 91 cams thing is a myth, but mines a 91 so I'm on the safe side anyway
