Changing T78 To Pt6262 For Torque

I am chasing low end torque in my R34GTR, so I am changing the T78(Dyno chart) for a PT6262 and adding poncams Bs on a strong motor.

I am booked in for the work next week and have asked for the car to be tuned for more low end torque. As you can see from the Dyno reading (as I was told) is bad and would be a bitch to drive, it is.

They said with the new turbo and cams they can tune it to the response I asked for and will be happy with the results.

Has anyone got a Dyno readout to show me what more Torque looks like on 338KW so I can compare it.

Hi Peter,

I can't comment on the PT6262 as I have no experience with them however would suggest you match the turbocharger to your requirements (power v response). The T78 is far too big a turbocharger for the power you're making and there are far more responsive options that will yield better results.

If you would like options feel free to give me a call.

Had a look at posts and it does help me understand it, my curve is very low and slow to rise , just like it is to drive, lots of gear changing and a pig to do step hill starts and goes hard after 5k. If I did not live in the bush I would hardly ever use the turbo.

Thanks everyone for that info and it helps me and it lets me see how laggy mine is.

When they are doing the work I will have them email me a reading, at least now I have some idea if it is going to be OK and I will post it before I go to Sydney to pick it up, hopefully you and others can comment if you think they have done a good job ?

My dyno torque reading just looks so dead compared to most of the others here with similar KW.

They said the motor mods etc will handle more power, maybe need more fuel but I have enough HP, I just want a fun street car not a laggy heap

Thanks Andrew but the car goes in on Monday for the mods

The car has had a lot done on the motor and was a work in progress, T78 was part of the build but the bloke ran out of money and sold it before he completed the build.

      Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!

      Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure

      A Brumby would probably fit a big metal toolbox in the back... this is how it begins

      Picked up a new OEM boot seal for the MX5 today as the old one got ripped a bit by me being a idiot by seeing if I could fit a large metal tool box in it, it didn't fit, and ripped the seal with the corner of the tool box I am still waiting on time to get the cams and new balancer installed, as well as the repairs to the boot Time will not be an issue soon though

      I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?
