im looking into building up mine NA (hopefully to 200 bhp) is it worth it to build it NA and DD it? or (since its my dd) should i just give in like many others and get a turbo? (i like the idea of NA much better)

all depends on what u wana do with it. if its just a car that u can enjoy and tool around in then go for it i like building n/a cars cuz u can do one bolt on at a time, not like turbo where u need a lot of things done at once. but to get 200 hp it needs a lot of work the ka sucks at na

can anyone confirm that this o2 sensor is for a KA24 or an SR20.

i'm looking for a pre cat #1 o2 sensor (on the manifold). seller might have mistaked it for the 2nd o2 sensor, but insists its off a ka24.

the shop i took it too said it doesn't fit on my ka24 pre cat o2 bung and that the sensor i received was for an sr20.

I can confirm that my rear 02 sensor from my '95 KA looks EXACTLY like the one pictured.

I think something is off, or it's really tired. This is from after a tune. Granted it did 149 on a mustang a few weeks later with no other changes.

Ebay 4-2-1 header
BC-264's
DIY 2.5" mandrel bent exhaust
Intake
Custom intake manifold
SR 370cc injectors
Bikirom tune
Some sort of irridium spark plug
PS removed
TB coolant thing eliminated

Oil analysis came back fine, compression was/is fine... the last time I checked it. Think maybe my BC264's arent doing what I want them to, or that the intake manifold isn't working out like I'd have liked.

Not really sure where to post and dont want to get yelled at for being a idiot and not searching, but here goes!

So im looking into buying a blown ka (spun rod bearing, head gasket etc) and rebuilding it for myself one day. i have a few questions i have tried to find the answers to but cannot.

1. I know the short way to write it , EVG or what ever. But what are all the componets needed to pass CA smog. i want to rebuild a reliable and smog legal engine, in my area i've seen a few smog checkpoints and i just dont want to deal with the hassle of RB/SR/Built KA. (not really one for power) dual cam.
2. Would after market Rods and pistons effect SMOG? i would like it just to be strong and built to maybe one day handle power, but this is for the long run.
3.i was reading somewhere that people do a cam swap, 248/232. are those after market cams, or stock cams? cant really find anything on those either.

i probably have a lot more questions, but none i can think of right now. if anyone has any info i would really appreciate it. or links you can call me a noob i dont really mind, i am anyways. thank you!

Different rods and pistons will not effect smog unless you change compression ratio, but even then you can still pass.

You will need to retain all the other shit though as CA does visual inspections iirc; so evap canister and solenoids need to be functioning, EGR, idle air, cat, no other CEL's, etc.

Replacing a Head Gasket

My 240 needs a new head gasket. Do I have to buy a whole kit (http://www.partsgeek.com/gbproducts/...L_6xoCGXjw_wcB) or can I just buy a head gasket (http://www.summitracing.com/parts/fe...sxoCAmrw_wcB)?
Thanks in advance.
