The GT3540 is a very nice turbo, and quite a good price. The problem I have read about is they only come with a 1.06 exhaust housing which is way too big for an RB25DET (more suitable for a rotary and RB30 and XR6T (the XR6T is a 3540 but with a smaller comp cover, .50 instead of .70 like you buy from Garrett).

You can get the turbo modified to a .82 exhaust housing which is alot more friendly and should start to make decent boost around 3500rpm. Do not go for any of the .6x sized exhaust housings as these are too violent coming onto boost and you will just wheelspin everywhere.

A guy off these forums fitted one on his RB25DET by the name of NisJet, it made 210rwkw on 12psi. His car has 3 inch exhaust, intercooler, power fc, fuel pump.

--- EDIT ---

Do a search for GT3540 and you will see a few people that have run them. Most that keep the large 1.06 housing have forged internals and need to rev the car to 8000rpm to make good power out of it. Also does that price include a new manifold? I think it was Roy on these forums a while ago wrote you need spacer plates to put it on the stock manifold or else the comp cover will hit, and it generates heat spots and warps the stock manifold.

I would always stick to the big jap brands - Zoom or HPI did a review of a range of A/M turbos a while ago, and it was proven that the JAP brands kick asre over the 'copy' series that you can get.

Makes sense to get something that has been specifically developed for your application, you can get some real bargains second hand. Try http://www.tuneagent.com/index.aspx and http://www.upimports.com.au/UPI_Parts/ as for starters.

    • 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.
