i guess i do. im just going by that chart, that says the G2 is rated for 450hp (not sure if its @crank or @wheels)

The chart say 450hp - that is not 450rwhp.

450hp is @ the motor... ALL turbos are rated in such a manner

You can check for a OP6 rear. We will have the the bigger rears soon. The engineering place just take their time doing it. Hopefully be available in Mid May.

Hello Stao!

I have a vg30det turbo 4V54 front with OP6 rear sitting in the shed. I would like to no how much for a high flow? it is for for my RB25DET Cefiro street car so i'm trying to keep resonse in mind while still achieving as much power as possible. Having said that, wats gonna be better ball or bush bearing?

The high flow will cost $800 plus $80 oil feeding line. We will be using ATR28G3's profile which should get you around 260~270rwkws (OP6 rear) with supporting mods at peak and not too bad down low either.

With R33 stock housing its very close to its limit, maybe another 5~10 kws once leak fixed.

With RB20 turbo's high flow I'm not too sure as I haven't had one dynoed yet. I guess its probably archive close to 230rwkws.

Wheel size wise this is using the a 71mm comp with 65mm turbine. With Garrett GT2871Rs its running the same size comp wheel but 53mm turbine.

I'm guessing you mean 71mm comp with 56.5mm turbine. I guess you use this on the larger rear housings as the stock R33 rear housing isn't large enough?

Would the larger rear housing turbo be suitable for a remapped ECU R33 car if only running 9psi? (currently runs fine on 10psi stock turbo)

As a replacement for stock turbo until I get off my arse and get injectors, AFM and powerFC?

We do use 65mm Turbine. Need some thing to flow as possible in a small turbine housing. If you can get a OP6 turbine housing we can use ATR28G3 CHRA with 76mm comp wheel. That will be able to get you over 250rwkws. You can drive it on low boost no problem, as for the best results get it dyno tunned with Power FC and supporting mods.

As for RB20 using ATR28G2 hi flow you can probably get some where between 200 to 230rwkws.

Any way adding some photos of the OP6 reared hi flows.

This is a complete ATR28G3 high flowed into a OP6 Rear housing (note the mark on the housing)

GT2871RS CHRA high flowed into R34 OP6 Rear with stock comp housing:

This is a Custom made GT3076RS in a .63 Rear internally gated setup bolton to stock Manifold

Will the larger rear be 0.7 A/R with skyline bolt pattern? I want 230rwkw at about 1 bar or less, I'm thinking a 2871 would get there easier with the slightly larger housing.

Is R33 rear housing 0.58 A/R?

And where did these 0.7 A/R housings come from? Couldn't they have made them 0.82 or something to flow a bit more?

The larger rear would be a .63 rear with RB25's bolton pattern. If you perfer 230rwkws BB GT2871 CHRA should do it fine. You can get that with stock turbo's rear housing. Stock R33's rear is only .48

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
