Hi All,

I need help on putting together an engine build plan. I have built a couple of engines before so enjoy getting my hands dirty but will need a support network and thus my first post here today.

Car is a Holden FE 1957 ute with the goal of Friday end of week quick drive and when ever possible club events and sprints. I am not after drag strip and dyno hero. With this in mind and the fact the ute only weighs around 1200kgs I am thinking of 300-400kw at engine should be plenty. I am also not sure if I go RB25, RB30/25, or RB30.

From reading alot of posts here

Option 1 - Buy full RB25 Neo for $3500 - mods, not sure and what to budget $???

Option 2 - Build RB30 $5000+ really need to know how to get this to a realistic build spec

  • Purchase RB30 engine from wrecker $400
  • Crank grind, new rings, hone $500 do myself
  • New water pump $200
  •  N1 oil pump $400
  •  Head port, valves, seats, cam etc $600 do myself
  • Cam 503TXM $500
  • Inlet manifold, ebay $250
  • Z32 AFM $100
  • Injectors 650cc and fuel rail $400
  • Exhaust manifold cast iron $700
  • Turbo, gt35, not sure what spec and what to budget $???
  • Wastgate, not sure what spec and what to budget $???
  • Gaskets $500
  • Intercooler 600x300x75 $200
  • ECU, not sure and what to budget $???

For a budget RB30 with  300kw  try to get a RB25 preferably Neo head with the manifolds and use the stock manifolds...maybe weld on a mount for a wastegate and make sure you hook up the VCT.

      What brakes on R34 GTT(Europe)

      By Dose Pipe Sutututu · Posted

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
