not at the moment cubes.

I will see how power delivery is coming on. I need to change the timing belt soon anyway so I will atl east get an exhaust cam gear then.

The turbo seems to spool earlier and earlier every time I drive it. almost as if it needs to bed in.

I am starting to think I would really lke a 3lt bottom end.

im running the stage 3 rb25 hiflow from aaron on my rb25 and it spools quiet early i know im gettin 16psi around 3500rpm lacks the mid range atm but from 5800rpm-7000rpm its animal..maybe stock computer doesnt like the bigger turbo?

Definitely doesn't like the highflow, rich and retard would explain you lack of midrange. Fuel pump and injectors could also explain why its an animal after 5.8k (lean out) if your still using the stock items.

walbro intank pump but stock injectors and fuel reg! yeh i really need fc,z32,injectors and tune!

is this the max oversize rb25 turbo for the rb25 engine?

Hey Phill. Yeah i'd think this would be the max oversize lowrb is talking about. I've just installed

one of the max oversize ones on my R33. Booked in for a retune in 3 weeks (as soon as i could).

Also will be changing from walbro to a 040, S15 injectors and Z32 AFM. Will let you know how it

goes if your interested. Also you work at Ford in Epping. Supprised i havent spotted you yet.

l0wrd what power u making at the wheels without the ecu?

on milanco dyno it made 279rwhp@12psi with stock turbo and standard coils

its got highflow and splitfire coils now oh boy did those coils fix ALOT of problems lol

im going to use the max oversize rb25 highflow the 260kw rated one, with custom injectors and power fc also z32 on 18psi. What power will i be looking at?

I have booked some dyno time on Wednesday as well. I only have an hour on the dyno so it will not be a complete tune. I will just be tuning the stock ECU at WOT and compensating for the GTR injectors. Mine is not the stage 3 max oversize turbo it is the straight rb25 hiflow.

So, is the change in the oil feed necessary when switching from RB20 - RB25 turbo?

I had mine changed a while back (running a std R33 turbo at the moment on my RB20), and the workshop claimed that it all bolted straight up fine, no modifications required at all?

Or is it solely to get more oil flow to the turbo?

You have to modify it for the Slide hi-flo because it is journal and not ball bearing. The bearings need more oil and if you don't do it right you'll cook them.

I have just gotten a bit further to getting some results.

I have just put in my GTR injectors and remapped the ecu to suit the bigger injectors and added fuel just for testing.

It is now spooling up quite a bit faster and I have set it to 14psi. it reaches full boost by around 4200rpm and feels very strong.

Cant wait to tune it tomorrow. it looks like it is going to be a good combination and may end up being quite streetable

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
