hey guys

i just got few quick questions, my mate has just built a 400awkw gtr with a t04z and he took me for a spin,

i was pretty amazed he had full boost by 4500rpm (26psi), and the thing felt so aggressive, the boost just came on hard,

now my question is will twins come on that hard cause, the feeling was unbelievable,

i was thinking hks 2530s, the car will be a weekend street car and will see the drag strip 2 or 3 time a year

thx guys

2530's wont come on as hard as that T04Z.

Has your mate got a stroker of anysort? That may explain the earlish spool up of the T04Z.

What are your engine specs... It will make things a bit easier.

do u know wat size exhaust housing his got on this t04z? i was so close to running a T04z on my GTR as well even bought the turbo and i went with the divided twin scroll .70 exhaust housing option for that extra response

i ended up just down sizing the turbo and going with a GT35 series turbo, it wasnt able to make the same amount of power as the T04z would but i wasnt looking for 400kw so it didnt matter

find out wat exhaust housing his got

little confused here, the gt35 will go 400rwkw... t04z is 450rwkw+ territory

way I see it is the 2530's sit somewhere in between the gt35 and t04z, either way its going to make stomping power and be making boost (ie making power) somewhere between 4300 and 5000 depending on your setup

the thing felt so aggressive, the boost just came on hard

So what you are saying is you like the TRANSITION from lack of power to lots of power? Not the lots of power ITSELF?

Then an even bigger turbo would be better, even LESS power then a much more potent transition to even MORE power. That would feel better to you?

Personally I prefer progressive power as I find the sharp transition makes the car very hard to drive fast. So the 2530's would be my choice, as they have been for many years.

Each to his own.

Cheers

Gary

Im going to be a smart arse so dont take this too seriously...

If you dont want heaps of power but like that serious boost kick, fit 2530's or similar and build in a valve that redirects all boost until it closes at say 5000rpm. So your turbos will still build boost as the car revs, but it all goes to waste, then at 5000rpm bang, instant 18psi or what ever you want. Probably loads of problems in what ive just described, but would be one hell of a kick going from no power to serious power.

Very silly i know :)

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
