stock bottom-end KA
528wHP /420 wTQ
More displacement = more gooder… 
kat ftw
The clutch is a 240mm 300zx XTD Stage 3 (not recommended due to how easily it glazes over and slips)
The internals are all stock, except for the head gasket, and the cometic head gasket does not change the stock compression.
Just bolt on parts.
stock parts = Camshafts, valve springs, valves, pistons, rods, crank, block, rings, bearings, etc all with around 200,000 miles on them.
200,000 miles that is impressive by itself
its gonna be interesting to see if it can make it past 5k miles with that kind of power.
wow… 30+ psi on stock 200k motor? ballsy
wow. :tup: hope it lasts
that pretty much go’s aganist every thing i was meant to belive. stock pistons? and a stock head? ftw
yea, its cool, but i dunno i’m a lil skeptical how long its gonna last especially at that mileage haha i’m sure they dont’ really care tho at this point
so u back it down a few psi and get some more life out of it…or u buy a low milage KA for dirt cheap and swap the turbo kit on it…i always said do KA turbo
thats awesome, ka turbo might be my next personal project.
Gets me thinking I should put a turbo on my Ka24e
My motor only has 102k I wasn’t thinking of turboing it with such millage, I guess this clip shows how strong they are.
after a bunch of internet searching a came up with mu own unofficial outline of boost vs hp, here it is - the cars that were soch are noted in red
now obviously each one of these #'s wasnt proven with a posted dyno test sesion, im sure a few were the owners “best guess” and a few were gtech type readings, or estimated using track times… but you can see the general trend as boost goes up
the original version had all the known mods noted, but its lost and all i have now is the short version i had postd on ubrf
5psi = 218 whp
6psi: 200rwhp 224 rwtq
6psi = 201whp 268 ft lbs
6psi = 213wrhp 226ftlbs
6psi = 215 whp, 237 tq
6.5psi = 201hp
7.3psi = 188 rwhp & 204 rwtq
7.5psi = 213whp, 238 tq
8psi: 220rwhp 251rwtq
8psi = 237rwhp
8psi = 248rwhp
8psi = 251 rwhp and 256 ft lbs
9psi = 225 rwhp - untuned - sohc
9psi = 232 whp and 254 ftlb
13psi = 288rwhp - sohc
15psi = 350rwhp
17psi = 310 rwhp and 316 tq
17psi = 326whp, 314ft. lbs of torque
17psi = 331hp - sohc
20psi = 314HP/273 on a 106* day & running 9:1 ratio
22ps1 = 435hp 391tq 22psi
24psi = 390 rwhp and 352 ft.lbs
29psi = 536.50 RWHP & 460.74 tq
30psi = 509rwhp
30 on the boost guage, 60 at the turbo
I wonder how much blowby that engine has now.
blowby is just how the rings tell you your cylinder is full
if you dont have blowby, you dont have enough boost …
That is sick, and I am completely suprised it has survived this long, but I am sure it won’t be long before it goes.
Impressive, but too bad you can’t spell definitely.
@ 200k deffinately a
“let’s see how much it can take before it blows so we can ge the stock record” kind of runs
@ 20% more displacement than the SR (AFIK stock bottom record is 424 whp) it made 24% more power.
KA owner-180,000 miles and still running strong I always see/hear of these things being little tanks of a 4cy. There’s a 9 second KADET on ka-t.org. I believe most talk about the 300ish HP range on COMPLETELY stock internals. Awesome stuff.
