hi there,i want to run a big single turbo on my GTR,first question is running a big turbo on a gtr is it required that i rebuild the motor,or maybe the question is whats the biggest turbo i can run on a standard motor,im not opening the motor yet apart from HKS step 2 cams and gears.i do understand its not going to get much boost in a standard motor,but i want to see what i can make without opening the bottom end.the cams will help with high cylinder pressures

i have a T88-34D and can also get a GT45.and iv heard i can get a TO4Z

i know what the first question will be and yes i dont care about lag,there will be heaps and i know,i use to own and pilot a 7 second rx3,so i know what it takes to drive something like this.

im not new to GTRs but have always just been a sheep and run small singles.i want big.

any and all advise is greatly appreciated .

You can make any figure, how long will it last though?

If you want it to last - GT35, about as big as you can push a stock bottom end reliably.

Otherwise, if you have the money there for the rebuild, boost away with whatever your wallet can afford

Big turbos... which make big power... and stock bottom ends, don't last. So no point having a big turbo if your not chasing big power

Im running a t04z on my GTR and it goes good. After a few problems with fuel delivery i've now got 337awkw's at 14psi. Stock bottom end with 260 Tomei poncams , Vipec ecu and supporting mods.

It is abit laggy, fullboost is at 4500rpm which isnt too bad, considering the n1 turbos i was running before was 4000rpm.

But im not going to be running anymore boost until i rebuild the engine as it simply wont last.

i just spoke to my machanic and he sugested the to4z.he said 350-375 kws....

im also looking at a GT45,the machanic has a R33 GTR with one of these big boys on it,runs 18psi and make over 650hp.

yes the bottom end is done but it was metioned that it was driveing on 12psi for 12 months making 510hp all day everyday before the bottom end rebuid.

350-370rwkw is right in the meat for GT35 territory mate :nyaanyaa:

a T04Z will run off 440rwkw, so unless your looking for that...

There is a big thread on GT35/T04Z going at the moment with lots of information for either side so you can make your own call there

      R33 GTR running -9 with no tune

      By Duncan · Posted

      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

      Coolant leak?

      By Duncan · Posted

      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

      Coolant leak?

      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?
