I'm trying to get my car in time and it's seeming impossible. I've pulled the CAS a hundred times and realigned it the the main pulley mark on yellow. It won't idle under 1100 to get it in time... My thought is whoever put this motor in might have used the n/a ecc shaft pulley instead of the t2 pulley. And yes my car is an n/a body with t2 swap. How could I tell the difference between the 2 pulleys? I know ones larger... Or can someone on this forum take a tape measure to thier t2 pulley and read me the size of theirs? And some do the same to thier n/a PLEASE??? I'm lost as to why I can't this thing in time right

 

Is it possible that the pulley is 90 deg off? Does it only bolt on one way? Or could this pulley be bolted on wrong?

 

Edit ^ I just pulled the pulley and found out it only goes on one way...

 

My motor is a jdm s5 turbo 2. Anyone???

 

it's not the pulley.They are the same size(N/a or TII).
check and see if the throttle cable has slack when idle.
The throttle also has a screw that you can adjust the butterflies on so that the idle can be adjusted...and you can adjust a screw on the BAC for idle I Believe.(I don't have any emissions or mess of vacuum lines on my engine so it is simple).

 

check check check and double check you are stabbing it correctly.

check to see if your plug wires are wired up correctly. use a timing light to check timing.

pullies are known to have different marks on them as the pullies and hub are a set. however, they are not soo far off that you will get horrible idle or blow your engine.

 

n/a or tii makes no difference on the pulley. The hub and pulleys are matched sets, if you think you have a mismatched set borrow a matched pair from a friend and restab you cas.

 

Cable has slack. I've adjusted the screw but any lower than about 1k rpm it drops to 500 and barly idles. And I forgot to mention I have no BAC or acv. And rats nest is removed.

 

I've checked it so much it's not even funny. The wires are on right. And I can't get the idle down far enough to check it with the light. When I do check it at 1k rpm it's 17 deg advanced.

 

The the problem... No one in my area is a rotor head... I got no one to borrow anything from or get advice from...

 

Using the palm pilot for rtek if I set the idle at just over 1k the leading timing on the palm pilot shows as 14*. So you're probably not that far off. I would consider looking towards a vac leak for high idle.

 

make sure the teeth at top left and right bottom aligned with the corners of the magnets and don't let it move one bit when stabbing. crank the engine with a 19mm socket wrench to get it in line. then set your TPS and with a timing light, that is powered by the car battery only, set your timing and be done.

 

Thanx that eases my mind a bit. I bet your right about the vacuum leak. I still have to put on the FMIC w/blow off cause right now it's just stock jdm s5 top mount w/o a BOV. Needless to say I'm not driving it like that.

 

Good to know 👍 once I put on the FMIC I'll look for further leaks cause right now I'm thinking my stock jdm s5 top mount is leaking.

 

Yes I've done this a bunch of times... And actually u wanna put the ecc pulley to TDC before restabbing the CAS... I've done it just like this but as quoted above I do believe I have a vacuum leak from the TMIC giving me most of the issue.

 

Sorry for the double reply I'm using the new rx7club app and didn't realize it loaded my first reply.

 

Half *** necro. The picture below RotaryRocket88 posted last year. If you look you can see the lowest load cell at just over 1k is indeed 14*. You'll have to get it under 1k to properly set timing if you have yet to do so.

 

I sure hope your not sayin that to me. And after the FMIC was install there's no more issue. So there was a leak somewhere. If anyone's half assed it the people who post negative comments instead of helping out (the whole reason for this forum).

 

Necro'ing a thread is bringing it back from the dead. It had been a few weeks without posts when i bumped it, thus calling it a half *** necro.

 

Ooooo dang I didn't know that!!! Sorry about that I thought it was some sly comment about the work I'm doing... My bad man... Thanx for the helpful picture it did put my mind at ease a little bit till the FMIC was put on and no more leaks. My idle is perfect after a TB cleaning. And timing is just peachy!!!
