Hi,

i want put a bigger turbo or hi flow the stock one? Which is better as i dont wanna change internals but want my engine not to blow or fry a piston. What is the best turbo for minimal lag, most power and a good amount of power at the wheels with standard RB25DET.

thanks

If you're after response and good average power across the rev range, then I'd recommend a highflow - good bang for buck and should easily see 220-250rwkw with the right supporting mods.

If you have enough coin and are after more power whilst still maintaining decent response, then the HKS GT2835 ProS is also a good choice.

Isn't 740cc overkill for anything under 350rwkw? 550cc injectors should be more than adequate.

Depends on how much power your after mate? and whether or not you may want more power in the future again!

again it depends on your supporting mods as well. sooner or later your going to need to change ur fuel pump, injectors, clutch, ecu...etc...and all of which costs more money.

imo, i'd go a HIFLOW. the hiflowed turbo will give you the best of both worlds, more power than stock and pretty good response as well. and best bang for buck!

my two cents,

goodluck mate

i would recommend the gcg hiflow, i had one of them on my rb25, got a vg30 ehxaust housing adapted to it and results were very good, i was more than happy with it. made 258kw at wheels on 15psi, my engine is built however but still expect a signifigant gain over standard turbo.

I'd go for a GCG highflow turbo. Personally tried and tested. Close to stock spool time, but huge power. It's ball bearing.

Bolts striaght up. No modding lines etc. Includes everythign you need e.g. gaskets, washers, etc etc.

Cheap -- 1750.

The precision turbo highflows in the group buy section are also good - 1550. ball bearing too. I personally haven't tested them, but I know people who have, and i'd get one.

      Unpeeling the Orange

      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!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
