Now price out, a GSR block, pistons, rods, Type-R head, cams, valve springs, retainers, type-r intake manifold, sir crank, crank pulley and all the other parts you failed to mention. Or can you just walk into Lucky Star and ask them for all this, and say since it’s just stock parts you only want to pay $1000?? And your theory is that if you can do it on a honda, matt can do it on his KA. Not to mention matt is doing this through a head that doesn’t flow as well as a GSR, i’m assuming 2 stock exhaust cams, and at best some mega squirt system that only controls fuel. I don’t think matt will be able to drive the car to the dyno let alone make 220 whp. I hope he can prove me wrong. ---

if you shorten the rod but use larger pistons you’ll still have the same effective strength. It’ll just be a lot less efficient since now you have a much heavier piston since its a hell of a lot taller. The only way I see doing it is basically shaving the block and head down a LOT (I dont evne know if thats possible) to a square borexstroke (or pretty close) if you really want to rev. But you ahve to ask your self the question: would that even be a worthwhile modification? You loose displacement and torque so you can rev… which is making more power only by more explosions, the amount of extra heat and friction created is rediculous, the engine will last about 0.1% of how long it would if you left it 2.4L. Think about it ---

All the talk about this KA stuff is pretty interesting. I wanna see numbers though. Dyno sheets, proper ones, with the types of mods the person has done. 1k for 220whp, not very much of a chance in my opinion. I would like to see it done if possible, but I highly doubt it. Anyone have numbers to prove it? ---

your smoking crack if you think you can get the KA to rev to 10k or 12k and stay alive for anything other than a few dyno pulls… why dont you calculate what the max piston speed is for our engine and you will soon see that it becomes very apparent that high revs are out…which means work over time is out…which means high horsepower is out… in fact ORF will pay out $100 to the $1000 engine challenge if it hits 200rwhp NA no nos no forced induction…i will come and watch the dyno to verify…adam ---

on my sohc NA engine…with the following ported head 503 lift 300 duration race cam air intake exhaust JWT ecu header everything else was stock…stock compression the engine made a WHOPPING… 143rwhp or about 164bhp whoo hoo so if you run stupid compression say 14:1 with custom pistons…you think you are gonna get another 57rwhp out of the engine? the increase in compression WILL not produce enough thermo dynamic efficeincy to make another 57RWHP… NOTE even with a 503 lift cam ported head and 300 stinking duration the power already started to tail off at about 6300 rpm… though the engine was revving higher than normal and could make 7k so lets look a bit deeper… lets say we CAN rev the motor to 8k, 9k, 10k and since the torque is not gonna jump up at the end we can look at what power it WOULD have made IF we assume the torque would stay flat like it pretty much has as shown on the dyno plot…lets say we can keep 110ftlbs thru that whole rev range 110x8000/5252=167rwhp 110x9000/5252=188rwhp 110x10000/5252=209rwhp… so ALL you have to do is either build up a motor like i did and get it to rev to ONLY 10,000rpm…or somehow pull some serious power out of the motor that SO FAR i have yet to ever see done…OTHER than all the mysterious “sunbuilt” GT motors that no dynos exist for …and where “reported” to have near 250hp… seems easy to me on a $1000 BUDGET 🙂 ![http://www.turbo240sx.ca/dynorun2.jpg](http://www.turbo240sx.ca/dynorun2.jpg) ---

IF you can get the revs than you can get the power… getting the revs is the key Forced induction is the way to go…WHY cause its stress loads placed on the engine are LINEAR…while rev based power places EXPONENTIAL loads on the engine… simple as that ---

Guys, many of the SCCA run-off cars are Nissans. They are usually SOHC and if you think they aren’t making well over 200 AND doing it above 8500 then you need to do more research. No offence to anyone here, but perhaps you should take a new approach on your next N/A build-up. ---

I thought that this was a given. WHo the hell wants a 250hp N/A 4 cylinder street car. The only reason to make such an engine is to fit in a certain race class. Other than that it’s a waste of time.
