i left my crank... hks pistons, eagle rods, balanced bottom end... 9k isnt a problem for it.. but i replaced my balancer for an ATI one.. :laugh:

builder said my bottom will live beyond 9k without raising a sweat... its in the balance i reckon

just out of curiousity is anyone running the n1 pump without the collar? I didn't like the looks of the collars as you have to carve down the standard crank so it fits on then drill holes in the crank, which didn't sound like it'd do many favours to the crank strength >< the n1 pumps fit onto the standard 32 crank, just not fully on (like about 2/3rds of the way on)

Stongly suggest not to do that, the inner gear will crack over time, not enough engagement on the crank. There are pics on what happens to the oil pump gear.

Can't see why a stock r32 pump wouldn't fit on. Wouldn't it drive all of the pump with an r33 crank?

oh really? i've seen them crack under stress and that sort with the collar kits as well :S Will have to make a decision eventually, builds being done atm (very slowly), but at least the n1 pumps will take more flack before letting go than the standard ones will, either way i spose

sum1 told me that the standard oil pump sits on about as much as the n1 would anyway? can sum1 confirm

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
