I thought it was the other way around - you can put the plenum/multiple throttle bodies onto the manifold if you drill some extra holes for mounting. That'd be a lot easier than drilling holes into the head.

just get a custom front facing or greddy plenum and run a 90mm throttle - it'd be alot easier and probably around the same money. Just look up JimX's custom front facing intake photos

oh, and nice to see a few more ppl from skylines stockholm joining us on the forums! welcome! :)

Hi guys, the RB26 inlet system goes..................

plenum > throttle bodies > inlet manifold > head.

The RB26 head has different bolt patterns, port sizes and water jacket spacing to a RB25 head. So the RB26 inlet manifold won't fit on an RB25 head.

If you want to know more, there are thousands of previous posts on this subject, do a search.

Hmm too bad cus the complete intake with plenium, throttlebodies and inled manifold just lie to no use in the garage. thougt i it would fit i could get rid of that stupid piping straigth over the engine an turbo..

but will the RB26 throttle bodies fit the RB25 Inlet manifold then..

Desperate to get down the intake temp. it's now really high.

and sorry searched but could just find that the GTR plenium wouldn't fit nothing more specific.

      Powder coating wheels

      I'm interested if anyone agrees with what you've said, and can give a good reason. Temperature of powder coating should be below any temperature you'd use to alter the wheel structure.  Powder coat typically 200 to 250. Annealing if that's what people are claiming would be occuring, starts at 300, and depending on the alloy, can need even up at 400+.   That's the only part I can think of that could cause an issue that people are believing it's from the rim losing hardness and becoming too soft.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By MBS206 · Posted

      Negative probe should be on the cars chassis. Positive on the wire.   Start as said above by unplugging everything (unplug the lights, and switches. Now at the switch, there is a wire from the fuse, to the switch, so out your positive on that terminal. It should read open circuit. If it reads something, especially a stupid low value, the short is somewhere between the fuse and the switch. If that's fine, now put the positive probe on the wire that goes to the headlight (at the switch plug). If it reads stupid low, the fault is from the switch, to the headlight.   Another quick test, is take the whole LED light setup from the left, and plug it into the right side, does it still blow the fuse? If you put the right hand side led light setup on the left hand side wiring, does the left hand side wiring now blow?  If the blowing fuse swaps from right to left doing this, your LED lights are the issue.

      Anyone know if it's a problem to powder coat forged alloy wheel centers (Rays/Volk GT-C). some say it's bad and can damage the alloy, some say it's not a problem.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By kevboost7 · Posted

      Hey guys, I'm reviving an old post but I'm finally getting around to working on this now. I removed the battery to get a better look at the wires and i traced the wires from the headlight to the fuse box in the engine bay, but the wiring looks fine? The wiring for the R/H headlight is 3 wires and then is bundled up with the large diameter wire that goes underneath the fuse box. I didn't take it apart yet. I know you said that its a short circuit somewhere between the fuse box and the headlight. But could it be the headlight switch on the dash? Also, i pulled out my multi-meter and set it on the Ohms, but i'm not sure where to put the negative probe and the positive probe.
