Hey guys im currently building an RB26 with an rb30 bottom.

the motor is out of a 32.

first things first. bottom end,

is there any difference in the standard rb30 block and the turbo block?

Can i use a crankshaft out of rb25/26 or does it have to be a rb30 one? anyone know how much hp a standard vlt crank can take?

going to put forged pistons and conrods (probably CP pistons and spool rods anyone used these before and how much hp can they take?)

The waterpump and oilpump are close to new so useing them shouldn't be a problem or is it better to replace them?

i was also told that i should put a reducer in the oil line as top end will suck heaps of oil and starve the bottom end.

thats about where my knowledge ends, i'm sure theres a heap more things that a required to do so im after some suggestions

For the top end was gonna put a big set of cams and a 1000roller of some sort... obviously goona need a computer to piss off the AFM and shit so which computer would use recomend i use.

If anyone has done this build before and has a list of stuff that had to be done/modified that would be helpfull.

      R33 GTST Axles

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.

      R34 Speedo not working after manual swap

      By Jarsky · Posted

      Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram  For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout) If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder

      Back on topic 😉, these are some of the notable pages from the booklets that are supplied with each weekly parts update. I never knew the BNR32 test mule car had an S13 Silvia body...

      After market rear camber arm adjustment

      By Jarsky · Posted

      This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.
