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?

shmiddy · 03-14-2008, 01:16 PM

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

whats ur set up like??

besTint · 03-14-2008, 02:25 PM

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?

besTint · 03-14-2008, 03:18 PM

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

besTint · 03-15-2008, 12:14 PM

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

describe the change in engine characteristics

blu808 · 03-16-2008, 10:07 PM

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.

rps13sh · 03-18-2008, 01:57 AM

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.
