    Swapping out the housing would mean new housing, new manifold, new o2 housing and new/modified downpipe. I'm not convinced that I would be getting the airflow numbers that I should be just by doing that, so I am reluctant to do this. I have never tried adjusting my cams, but I doubt that I could make a good enough change with the adjustment alone.

    That housing is choking the sh1t out of that turbo.. I now have two versions of the 67mm turbo.. one has a stage 3 t31 turbine and one has the p trim turbine at the same boost levels the stage 3 chokes it BAD in a garrett .68a/r housing when in the same a/r housing with a P-trim it's using MUCH more fuel and making a lotbetter power at the same boost.. i just like the strong pull starting earlier with the stage 3 t31 wheel although it's cutting peak power down a good bit

    I made 530hp and let off mid pull because i was over 100% duty cycle and shot way lean, i hadn't even gone past 7500 RPM and wasmn't near 30 psi yet this was with the p-trim, i need bigger fuelers :D at that same boost i have plenty of fuel with the smaller turbine because it's just not fl0owing the air out to let enough in to make good power.. the bolt on housings have always beena restriction and on a turbo this size that's like breathing through a virginia slim ciggarette for your air to run a marathon

    There are two things that make me wonder though... One, I know someone very personally who had a 2.0 (better head and cams than my motor) and ran a bolt-on PTE5862sp (when they had those kinds of combos available) and he was running around 30psi on E85 and he trapped a hair under 130mph. So a better head and cams on a turbo with a smaller compressor wheel and same exhaust side was making VERY decent power, a lot more than I'm making. And then there's this thread: 500hp with PTE6262 bolt-on turbo.

    500fwhp on a 2.4L with a bolt on housing... Now why can't a 2.0L, do that?

    well a better head and cams makes more flow and flow = power.. a 2.4 has more displacement, more displacement given the same power adders = more power

    That is true, but to trap 130 you have to be making very decent power. I'd say around 600whp maybe a little less?

    Tue, although i'm not sure o the power to weight equation and i'm eating now so i can't look it up. all i was driving at is that every setup is different and will perform different. I've personally seen in my own car losses and gains depending on how well the timing belt was aligned.. in my case i can't set the cams perfect and then get the crank right i have to do the trick wher you put the exhaust cam a bit forward, clamp th belt on and rotate it back where it's slightly below leel and the intake is slighly above, then do the crank, otherwise i end up with incorrect cam timing based on true TDC and there's a difference in performance there. it's attention to all the little details that really make a fast car fast, especially those doing so much with so little.. if your car is healthy you'll get there, it's just a matter of streamlining everything in the airflow, maximizing that flow and making sure everything is perfectly in sync to perform together

    personally i find putting performance stickers all over mytuning laptop has made a nice gain on my ride :D

    Not even close. Would barely need 500whp to trap 130 in a normal weight DSM.

    Any 6262 users running the T4 turbine housing?

    In a full weight 2g AWD? I don't know if 500whp is going to trap 130 on a crappy launch.

    Car is still down although i'm a good way through with the trans. I have been so busy and the cold has been on and off (this weekend on).

    It's quite possible. Unless ## driving around in a 3600lb pig. At most 550whp is all that's needed. We aren't driving 4k+ lbs. 1960's land yachts.

    Yes I am.

    You have a very nice trap, what are you making at 3100lb?
