For you guys running itb setups...do you have filters on the or run them open like that?

KA240SX808 · 02-19-2008, 10:25 PM

Most run open

svensko · 02-28-2008, 08:58 AM

Everyone talks about the head being so restrictive on NA KAs. Has anyone considered trying to swap heads with other nissan four cylinder engines? I'm not sure if any of these would come close to fitting the KA without MAJOR work, but it's worth looking into at least. I googled but I couldn't find anything with the head "footprints" to be compared to the KA's "footprint". Hell, even head gaskets comparison might be enough to get a general idea. I may look more into this later today if I have more time.

If this idea is completely stupid, then please forgive me. Please note that NO I am not a machinist, NO I do NOT know how much work it would be to modify heads, so please don't lecture me on being ignorant, but please provide some sort of indication to the degree to which the heads do not match.

Some Nissan four cylinder heads that should be considered:

SR20DE
SR20VE (I've heard this head flows rediculously well)
FJ series
CA series
CG series
QR seies

Yes I'm aware that most of these heads probably flow much worse than the stock KA.

edit: Yes I realize that if a head does match and does flow better, then the next problem would be the timing chain, and cover, but one step at a time.

KA240SX808 · 03-01-2008, 01:17 AM

^From what I've read is that the KA head was the best flowing of it's time???? Not sure it;s true but there is a possibility.

Perhaps the Newer Frontier Heads were improved?

do anyone kno how much it would cost to get valve reliefs milled into the sohc pistons??

project-D180 · 04-13-2008, 11:21 PM

is anyone runnin je 11:0:1 pistons yet??

KA240SX808 · 04-14-2008, 12:06 AM

^Thats news to me, I thought the Wiseco 10.5:1's were the highest.

project-D180 · 04-14-2008, 02:02 PM

any updates on this oh so sexy thread or it all went fail?

joshy240sxxx · 06-29-2008, 11:20 PM

whats the most hp you can get with a NA de

project-D180 · 06-30-2008, 10:27 PM

no one really knows yet..but we'll kno very soon if people dont loose hope jus waitin on other people..my project 1 is already under way..

project-D180 · 06-30-2008, 10:35 PM

90 pistons,eagle rods,xcessive intake mani,n60 maf,light flywheel,stge2 clutch,shaft masters aluminum drive shaft(free shippin i might add so check'em out),ported exhaust side of head,obx headers and pulley kit(crank pulley,power steerin,water pump,and alt),248x2 cams,and knifed crank..and maybe a retuned stock ecu from EFI Specialist (Powered by CubeCart)..lookin 2 put out atleast 200 to the wheels..if not i have a project 2 that will consist on 11:0:1 je pistons n head work and bigger cams..so come on people stop half a**in and let get this N/A thing goin

block is done..hahahaha!!!head is comin soon...

do i really need this or can i take it off and plug the line???

Bigsyke · 07-13-2008, 10:47 AM

^^^I would keep it. Others may say you can remove it. I'm not sure on nissans but other cars like hondas, the Evap purge kicks in on decel (55mph-15mph). Suprisingly in warmer climates quite a bit of fuel is evaporated if the EVAP isnt used, this container contraps it, and vacuums the vapors into the IM to be burned, which has 0 affect on performance- however more possible throttle response from sealing a port on the VC. You may notice a slight decrease in your MPG if removed.

If the car is tracked only, rip it out. Just my 02

project-D180 · 07-14-2008, 09:24 PM

ight thanks for the tid bit...should be droppin it in soon ...will be postin pics and info soon

Bigsyke · 07-15-2008, 03:52 PM

I thought boring out the KA to 2.6 would drop the RPM revs to like 5500 instead of its 8000. You would get some nice torque but wouldn't this be useless for drift/track/ I only see this being used for 1/4 times and thats it. In which case I wouldn't bother.

not true. The crank is FCW, and allows RPM's over 8000.

project-D180 · 10-11-2008, 10:15 PM

what u guys think rom tune or afc??

mondojackal · 10-12-2008, 01:22 AM

just get a JWT tune. it's not that much, and they'll retune it for you if you change something.

has anyone seen the newest n/a KA record?
