250 RWHP on a NA KA ->possible?
Hey, I was talking to this guy from another forum about the KA. He seems to know what he's talking about and said he's built a couple of KA-Ts and NA KAs and said that most people believe the KA won't get over 200 hp at the wheel because they don't know the engine that well. Anyways, I told him I was looking for about 250hp at the wheel and he gave me a rough list of what would be needed. Think it's true?
10.8:1 compression pistons
Nismo or PDM cams
3 angle valve job
Unorthodox Racing Pulley Kit (Full Set)
Light Flywheel
SR20DET 370cc Injectors
JWT ECU upgrade or SAFC
Intake
Header
Exhaust
High Pressure Fuel Pump
I'd like to believe so, but it's one guy against the masses. If it's true, that's a major sleeper. 250hp w/o the lag of a turbo or anything hinting towards NA power.

The most I've ever seen from an NA KA is about 250 rwhp. However, that was a SOHC ITA 240sx. They also spent about $8k on that engine...

my guess would be
bore it out
raise compression to 11.5:1
new valves, cam shafts
3 angle valve job
p&p of all intake pieces
widen exhaust put complete custom exhaust
bigger crank shaft
of course you'd have to do stuff like new ignition, new ecu, bigger / different radiator.
give or take, yeah 5-10k will get you a very well off engine..
i've seen a h22a at 290whp, he spent 12k on the engine, but it can be done.
I don't know why people don't have that strong of trust / belief in the KA engines.

Its not that they don't have hope in it. Its the fact that, would you spend $8k for something that can be had for less than $2k?

A properly turbo'd car should have all of the NA upgrades anyways.
well, maybe not ALL, but it should have some... compression is one up for debate.
Why make a nice car fast? Why not just buy a civic and a fart pipe?
Sorry, I'm the type of person who doesn't 'go with the crowd'..
just IMHO

That right? So how long after seeing a 240sx in a magazine before you actually bought one? I bet you wanted to 'go with the crowd' and buy one....

I really haven't seen any in magazine's, because i don't read them.
I got a 240sx because the chance was given to me for really cheap. My last car project failed, mainly because i hated the car and didn't really want ot do anythign with it. So, now i have a decent platform to work on.
I haven't seen a hatch for a long while now, seen a few coupes.
I apologize if it seems like I was flaming, just the general answer seems to be 'swap this' or 'turbo that'..

Don't let this get out of hands guys...be mature, or take it to the PM.
I think 200rwhp is realistic, not 250. There is someone around here(La canada)that has a N/A KA that supposedly has 230RWHP. No n02.

And no I'm not just saying that because I'm the next drift king - I'm saying that because financially it makes more sense.
BTW I was one of those guys who saw a 240SX in a magazine (Motor Trend, road test buddy) and I would have had a 240sx years ago if it weren't for, uh-hem - financial.

if it were up to me, i'd stick with the ka. the torque you get out of it is insane. good ol' truck engines.
plus....its a lot more legal than swaping in a sr20, which would be sick cuz u get jdm. but the way i think of it, mod your car and make it like new, or get a new one. so 10k isn't bad for a "like" new car, that'll be damned fast

i would just like to comment that it is very possible to get a KA motor to 250+hp... care to take a look?
