Thanks mate :rofl: If the weather holds up I'll get to try out the Nittos tommorrow.

Yes, very true. Stock and modified GT-Rs are very different beasts to tame, naturally stock being the easier of the two.

Emre- they're very impressive times there, 124mph!!!! I guess if I get my 60' times in the low 1.73, I might gain a tenth of a second or two.....

Calder was fantastic last night, had a total of about 7 runs, not that many cars, and perfect weather.....

Penfold- yes bolt straight up, providing u get the kit which suits the rb26.... From what I've heard they are an awesome turbo, very responsive and make good power.....

Anyone here wanna share their experiences with these turbos?? *looks at vspecv*

A good friend of mine is running a single AX53B60 on a Pulsar GTi-R - this thing is a rocket! Lag? What lag!? Full boost by 3000rpm! He also confirmed they are about the same as the HKS 2530 - perhaps a touch better.

Just wondering who you have had good tuning experiences with in WA as I may be looking for someone soon.

The best in the west certainly does not use dynapack and his dyno dynamics dyno is extremely accurate - if anyone can reduce a chart I will attach my latest chart (not the one below)
i have only fitted them to 1 car a customer running a motec, but they were awesome. better than 2530s, peak power pretty much the same, just more responsive.

Hmm.. that's very interesting: less lag is always good :P Anyone got actual figures, or better yet, a comparison between the two?

LW.

hi got the t78 which spooled up round 1bar on 5500, what type of power figures are the t517zs you have rated at in total as a pair 600hp 650hp 700? and at what boost? might be worth swapping to keep it all undercover thats all.

:cooldance

Hi Emre,

Its not that I want more power (not yet!!), I was just stating that how the JMS drag car can get 381 rwkws on 1.3 bar boost?!?!?!?

they usually run a mixture of toulene, acetone and avgas, you could say its rocket fuel... it makes ALOT of difference to the output of the car, much more boost and timing can be fed into the engine without detonation coming on, and thats how they make there power

they do it with most of there dyno runs, marketing i would assume, as not many people know what fuel they run and all they see is there power figure

they made 293rwkw on an sr20det silvia with a single T517Z, fuel ratio was as below:

avgas:toulene:acetone -----> 6:3:2

The T517Z's are rated at 600 hp, got my engine rebuilt last month and got dynoed a 335rwkws at 21psi...... full boost by 5000rpm

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • 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.
