Hey guys i have been wondering for awhile about what the difference between the RB20DET head is on the NA version and also FI version!

i knw the cams on NA is slightly bigger but wat about the rest? and is the NA head compatible with FI block? i beleive it should be as they are both RB20's but would just like to confirm.

thanks

no one knows what the f**k you are on about and it apears to not really be worth asking

I wouldnt say that dude.

Using FI (forced induction) as a replacement for turbo is a bad idea for starters though in terms of the community.

Either way, I cant answer the question hah

I would assume the same, bar the cams - someone else would need to confirm

hey mate, no difference in the heads... cams different, but thats all... springs etc, all the same...

as for using a FI bottom end with a NA head, it really depends, if you are changing to NA pistons to up the compression ratio, then there is really no difference to using the NA block (though the FI bottom does have squirters, please correct me if the NA bottom end does not), and there would also be the issues of blocking the water and oil lines, if going NA...

really, it would be alot easier to use the bottom end that suits the application...

cheers mate, hope this helps...

"no one knows what the f**k you are on about and it apears to not really be worth asking"

as for this absolutely useless statement, your no better, than what your accusing the bloke of... really useless

      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.
