Ok, my RB20 has stuffed a big end bearing, so Im going to need to do something about it soonish. The problem is I have a pretty tight budget.

My options the way i see it are

A) Rebuild a lower K RB20 and swap it for mine.

B) Get a stock 4WD RB25DE, stick my R34 turbo on it and remap my R32 ecu to run it.

Im thinking I could probably rebuild the RB20 for around a 1k including buying an engine, but after reading 666DAN's posts I really like the RB25 idea.

Can anyone give me a ballpark figure on buying the RB25? (has to be the 4wd one remember).

What injectors do the NA RB25's have?

Would I be able to get it back up to my current 200rwkw?

Any help appreciated

Depending on how long you are prepared to wait and how much you want to pay, I'll have a healthey GTS4 AWD RB20DET motor coming out of my car soonish. It'd save you money with being a bolt in, and not have to fark around making sure everything works.

na rb25 from an R32 has the same injectors as rb20det

about turboing it?

I don't know..

I'd go another rb20 or have a look at my HYBRID RB thread in this section where someone posted a link to building an RB24 and 22 and so forth.

however, if you really want an upgrade, you need the money.. then go rb30det or rb26dett

Its actually a T70 turbo - heres what he said:

I'll be finishing the Cefiro with the RB25DE + T70 later today so I'll scan that when we're done.

Last reading was 249 rwkw @ 17 psi

Completely STOCK RB25DE with a T70 600hp, 600x300x100 FMIC, GTR Injectors, Z32 AFM, Desno 600 hp Fuel Pump, Remapped R32 GTST ECU, and that's it.

Yeah i have a problem with my RB20 as well and may need a new engine.

How much?

I've never had anyone be able to give me a straight answer on what is wrong with my car. I think its cursed :

      r34's love to squeal

      By Nizzy_R34 · Posted

      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.
