Rb25 Neo N/a Turbocharging

Hey everyone, I removed this RB25 neo NA from an R34 GT. I want to make it turbo and put it into my R32 4 door. I have all the bits sitting arround so i want to try do it cheaply. Its got 53 000kms on it, so first thought was maybe put a thicker head gasket on it and put the stock turbo set up from the r32 onto it, and run low boost. But then it would not cost too much to put an rb25 turbo bottom end into the non turbo block and make it a VVT rb25det. Im just wondering weather i would need to get pistons only , or do i need to get turbo pistons and rods from an rb25det?. i would also use the box from the NA r34 which looks like an RB20det gearbox. sitting arround i have a rb25 greddy copy plenum , rb26 injectors, car has hks exhaust and front mount. Any suggestions appreciated.

Cheers, Mark.

I'm fairly sure the plenum won't bolt up to the Neo N/A cylinder head.

Just leave the bottom end together and run the normal 12-14psi from the stock turbo. You won't have issues, it will actually make more power.

cheers mate

, Bummer if the RB25DET GTR style plenum doesnt fit the RB25 neo N/A head!, Can anybody confirm this ?

    • OK so I just bidded $500 on an R33 GTS4 that no one seems to want. Waiting on a call from the agent to see if I won. 32 GTS4 is for sale. I can't deal with the temptation to mod it.
    • Might be there for work later in the year. Wouldn't mind catching up with you fellas - can't have too many beers, but will consume copious amounts of takoyaki while executing an asian squat on the side of the road while you blokes sort out your hangovers.
    • I know one example is a anecdote not data, but I'm running the same Aeroflow 525 at full voltage through a regular relay, and while I've had other fuel problems including melting the factory fuel hat, the pump itself has been fine for years. Of course, they aren't *that* expensive these days, you could swap in a new one and see if the issue is resolve. I think you had a previous thread about fuel problems, have you been monitoring and logging fuel pressure? Is there anything voltage related (for example does the voltage go up when the pressure goes down)
    • Slap a 460L into the car, send its mum.  
    • So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again.
