ronin09 has tomei poncams w standard turbos. i'm sure it's been done plenty of times. I have adjustable cam gears on mine with standard turbos also. i found a similar gain by adjusting them (around 30rwkw). both our cars are running at ~250rwkw.

what he said^

just under 14psi for me. cams are standard cams with an hour or two spent adjusting both inlet and exhaust cam timing.

from memory ronin has the 260/260 duration Tomei poncams (9.5mm lift?). also running around 14psi.

interestingly i was just comparing our two dyno graphs. my peak was 253kw as was ronins (though we tuned a bit further and ended up with 247 peak, but more mid range torque).

Comparing at points along the graph it's interesting to see that ronin has just a few more kw's at each point but the shape of the graphs are virtually identical. interesting that two different set-ups tuned at different places ended up with near identical figures, and identical curves!

they are the same cams i have in my gtr, i have standard turbos.

im not sure how the new cams are yet..

I'm slow in the uptake today.

what he said. 260 / 260 9.15

I wouldn't expect too much gain on stockers, apart from boost coming on a little lower - BB - I don't have plot of PSI vs power, but can you compare where boost / power ramp ups are between the two graphs.

They will help breathe alot better with some slightly larger twins.

    • 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.
