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.

    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
