Hey guys,

Im actually thinking of doin something a little different. Since its illegal for me to drive an R33 Turbo & my turbo motor is now blown i've though of popping an RB25de in it with some high comp pistons and cams... Atleast this way id be able to drive the car anywhere without any headaches.

The car would still be driftable on the track as i have the supporting mechanical diff, suspension et etc.

Just out of curiosity, has anyone done any internal work to an rb25de or have any advice on this..??

I must also admit, i do have a soft spot for quick naturally aspirated cars... :(

Theres a few good threads and an awesome sticky in the NA section of these forums..

I would definately say that it would be very driftable.. High CR means you have a lot of responce and torque..

I wouldnt bother getting high comp pistons when you can just as easily shave the head/block to acheive a high compression ratio and simply replace the piston rings to ensure that you wont have any problems.

See you in the NA section.. :action-smiley-069:

      r34's love to squeal

      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.

      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.
