Hey everyone,

I want to build a descent motor for my 31, at the moment im on my green P's and i want to be able keep it on the road legally and to drift it on a dry track with out embarasing myself.

So i need to know if its worth building an N/A motor ,building a turbo'd motor or just getting an earlier model stock turbo'd Rb motor?

Keep in mind I'm looking for the cheapest way to make power!

lots of info on the r31skyline club about turbocharging the rb30e engine from using basic vlt ecu/injectors/manifold/turbo thru to cam changes, ecu upgrades etc etc many guys are making 400+ reliable rwhp from original, internaly standard rb30e motors with cam and valve spring upgrades. my ti has original 300,000ks and 350rwhp and been turbo'd for around 7yrs

If u wanna do dry skids in a 31 and well go turbo. Depending on budget all the available rb turbo motors will do the trick. Like jon says id just turbo the 3 litre. Im running a bone standard rb30 bottom end in my 26/30 d r. Running 22 pound and loving it.

Change the cam, get an a/mkt ECU, set of quality headers and a bigger exhaust and you will be looking at upwards to 140Kw at the fly and 100% P Plate legal.

And have a great base to work with another day.

There is a lot of good things to come from high compression turbo applications. Post P territory, just source everything from a VL turbo and you're away.

If you have plans on keeping it for when you get your full licence I'd throw some forged pistons and put a rb25de head on that means when you get your full licence easy as to turbo it. I've done it twice now, awesome power and really easy to do

    • 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.
