Hi Guys haven't been on here for some time but I am looking at rebuilding my RB25Det in the R33.
as I have low compression in one of the cylinders.

looking at going the forged path..... motor was making close to 300rwkw on the standard motor with the other mods.
(450hp Garrett BB turbo, Nismo 555 injectors, cams, Altronic ecu, large exhaust & FMIC)

Is there any good places or websites to buy parts for a forged rebuild or kit?

  • Forged H Beam Conrods
  • Forged Pistons
  • Head Gasket
  • ACL Race Series Main Bearings
  • ACL Race Series Main Bearings
  • ARP stud kit
  • Gasket kit

    Will get the block machined, what else will be needed?
    the car is street driven (weekends), might a track day in the future.

I have a stock motor that goes to the track every 2 months or so making well over 300kW and it gets the shit thrashed out of it.

Best move for you, install a stock RB25DET NEO motor, a GTX3576, twin gates, twin screamers and spend the change on cocaine and strippers.

research:

stock RB25DET NEO

ARP headstuds

E85

1150cc or 2200 Injectors

Walbro E85 450L pump by TI Automotive

Continental Flex sensor

Adaptronic/Haltech/Nistune (R35 / HPX AFM if going Nistune)/ViPec or whatever makes you hard

Anything billet turbo, such as Hypergear SS2

Great guys to deal with, maybe not the cheapest around but quick delivery, can return unused parts, and he will order in anything specific if he doesn't have it.

Check out his Facebook page, often does nice giveaways and he actually has a few nice random shop cars aswell

I got all my bits from CJ motors, give them a call and see what they can offer.

To run big boost, I recommend a set of Super tech valve springs and valve sets.

    • Just as a thought, if it's in neutral, thats your drive line disconnect, not the clutch. Clutch slip at the dyno with pedal fully out, is actually adding a second disconnect. So it's not a clutch issue if you're in neutral. Just a bit of friction dragging the output around while in the air.
    • The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.
    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
