HKS 264 CAMSHAFTS + stock motor
 

should i experience any kind of power loss with these cams on a stock SR motor? i fired up my car last night after changing out my headgasket and while i was in there, i replaced my camshafts with the hks 264 that i had laying around. it has a rather rough idle which i expected but theres no power. almost like an engine lag. anyone?

have you correctly set your timing?

check the timing of the cam shaft to the engine. could be all fucked up..

whats ur set up like??

my timing gun broke. gotta find me a snap-on truck to get it replaced. so that could be it? the timing? its not like ecu mapping or anything?

Or you could set the car to 15* BTDC on the compression stroke, then pull the CAS and restab it. No timing gun needed that way.

are they step 2s??

i have hks 264 step 2s and they make the car really laggy, untill i see boost... how does your car act when you are seeing set boost?

yes, they're stage 2. yea its laggy, then when i punch the throttle it bogs out like at 5 or 6k rpm.

setup is:
blacktop SR w/ redtop #62ecu (E5 wouldnt pump fuel)
new stock manifold, new, turbo, greddy down, hks catback, apex metal gasket (does that affect anything major?) , greddy intake, blitz bov, fmic.

is the ecu tuned? you might be outflowing the maf if your still on the factory one. you should at least be running z32

nevermind. found some vaccum leaks. always something simple. runs fine now. its awesome now.

its a beast!!!

describe the change in engine characteristics

If they are the step 1 cams it should have a good idle if timing is correct

step 2 should have upgraded valve springs or you will have problems.
Add a greddy intake manifold asap, o and those cams will suck all the cfm's out of your turbo.

its he lesser of the stage 2 and a couple of shops said they're fine without valve springs. idle is pretty stable but sounds like its growling.
