I have been building an rb25det s13. I have just started it last weekend, I started it with some temporary pvc pipe from turbo to throttle body and its sounding like its running on 5 cylinders. It doesnt idle and the engine shakes a fair bit. I have spark in all 6 cylinders also. Just wondering if it would do this due to not having the idle speed controls plumbed into the intercooler piping so the afm can read them.

Any help would be great

Thanks

Nah, Id say its probably 6. It was my mates engine out of hes r33 that he gave to me for free. When i opened it up to give it some new seals and gaskets it had dents in combustion chamber from a spark plug failure. No valve looked bent and im pretty sure it has same compression as all other cylinders. Il check it later tonight.

All injectors are firing, All plugs are firing. I know its #6 because when i take the plug out of coil pack on number 6 it sounds the same. But when i pull the coils out and put the plugs in them they spark. Also the other 5 cylinders have 175psi compression. #6 has 150psi. Ive got a brand new head that il start to assemble and il just throw that on when i finished the rest of the mechanical.

Maybe ignition module, sits on top of the coilpack cover.

well all the plugs have spark. Would they have spark if im running a series 2 ecu (built in igniter) and also a series 1 ignition module?. The whole car is built up of all different series r33s and silvias. :S

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
