He went with a 6466 T4 divided 0.84 so I'll wait to see his results and then decide on what I do.

Interesting point i just saw is that the 6262 is rated at 705hp, the 6266 at 735hp and the 6466 at 900hp!! Damn that is a massive jump from a 2mm bigger compressor wheel and additional blade.

Most of the Emo and Rexxy boys think the 6466 spools very similar to the 6266 but makes a lot more power. That really doesn't make sense from Precisions point of view. In any case, it seems the choice might come down to 6262 or the 6466 - the 6466 is one big turbo for a track car....

That is just crazy, man! Nice work :) Was the 6766 totally maxed out?

Thanks mate, hmmm not convinced yet, I will give you an answer when I'm done with this one. 6766 will go back on next with a slightly bigger housing to see what they can do.

as usual..i tip my hat to you P.J, track looked good for running numbers!

cheers

Thanks Darren! Yes track was killer but suspension still far from ideal, 1.40 60 on the 8.9!

Congrats man, that's massive.

What power/boost was that at?

Cheers John, 44psi, no idea on power. Given that it made 636kW at the wheels on 42psi, I would say in the 650kW region.

I was thinking about getting a Precision PT6262 for my RB26/30, have had a look on eBay $1137.28 delivered and Powertune Australia looks to have dropped their prices to$1150, only $13 difference so i ordered through Powertune Australia as they have warranty for the turbos as well as the support! I am excited and can't wait to test this baby out!! :)

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
