Meh they say OEM is the best but obviously most expensive. Spitfires would be fine. they generally consider spitfires as an aftermarket upgrade. as for plugs your 4 dollar plugs will be fine just make sure you change them every second service

ok to clarify things: Both NGK, The BCPR7EY is a "copper" plug, roughly about $4 ea, The IRITOP7 is a racing iridium suitable for extreme turbo use and are about >$30 ea! *general iridiums -IX are not really suitable for high boost, but the IRI- series is and was its sole purpose for development (They are the same as the Nismo & HKS racing plugs)!

FYI: RB25 use BKR7EY and IRIWAY7. *difference being that one uses the ISO standard & the other JIS, meaning about 1.5mm difference in body length, both compatible with each other in most applications.

These plugs are 0.8mm gap std! * (where as, a 1.1mm gap plug carries a suffix of -11, a 1.3mm is -13 etc etc.)

At 19psi using '7' would be spot on, especially for street, but if your doing serious racing or vmax challenges then id recommend '8'.

Coils, Splitfire are good, but personally I'm looking into Okada Projects as they seem to be awesome on paper & I would be able to open the gap up to 1.1mm or more by the sounds of it (better emissions, economy etc)!

      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?
