Thanks heaps for the information here, and yes i love the efr turbos but my wallet and budget hates them haha Just spoke with hypergear as far as hybrid stock turbo arrangements go and they have a t28 based billet wheel chra that they can incorporate into stock housing with stock positioning that he tells me will be more than capable of the 450kw goal i have set and the utilization of stock mounting position etc is a massive plus to me.

Yeah im struggling to find much info om these turbos attop a 3 litre engine. I can always pass them along and buy another set of turbos. What would be the best turbocharger for a trade off between response and power >8000 rpm. And yeah 4inch mandrel bent system was planned with one high flow box muffler from hooker headers, they sap minimal hp

Thanks for the info guys, read the oil control thread and it was very informative. I have print the thread and give to my engine builder to read. Is there any benefit to using the rb26 studs as opposed to the rb25 studs ? My engine builder is family so any thing that is labour only intensive is free. If for no extra cost wouldn't it be worthwile ? And yes restrictors will be installed as recommended. Any opinions on the turbos ? And how they will perform

My fabrication skills are pretty reasonable, so a larger capacity baffled sump definitely wouldn't be out of the question. As far as not needing the head return and just using a catch can, isnt that somewhat of a bandaid solution? If the oil is not pooling in the head and is flowing back to the sump quickly there should be minimal oil blow back yes? Or am i over complicating haha? And any suggestions on a modern fuel pump solution to support 500kw on e85 ?

Hey guys, Long time lurker but have just opened an account so as to ask for some advice on a few things in my upcoming build i have been piecing together for some time. It is a 3 litre rb30dett build I am using the head and intake off of a r32 gtr and a built rb30 bottom end The specs when finished should look something like this, bearing in mind there are still a few things needing to be purchased. Rb26dett head, stock refurbished w upg valve springs and stock cams, 20 thou shaved off head face, rear oil drain back mod performed. Rb30 block, decked 30 thou, deburred and painted block walls, extensive oiling mods performed. Cp pistons with head mods and gasket choice 9.6 to 1 cr achieved. Spool rods w upg rod bolts Arp main and head studs, block prepped for 12mm rb26 head studs Cometic gasket Stock intake assembly rebuilt 600x300x120 garrett core intercooler Id2000 injs Twin 044 pumps Nismo fuel reg Stock r32 gtr exhuast manifold match ported with minor head exhuast port clean up performed too, ceramic coated. Trust t517z turbos Hard intake piping kit Running rwd only with built box Running on e85 Haven't purchased an engine management system yet as still deciding and will collaborate what my chosen tuner will be able to work best with. I would love on final tune of 25 to 30 psi be able to see 450rwkw with very very strong midrange and no more than 8000rpm Does this seem achievable to you guys? My main concerns are with wether or not the turbos will flow the amount of air required to produce the power goals i have. Now i know full well that it is jusy a number and my main priority is the delivery of the power and area under the curve. I have chosen to try and push the stock cams as the shorted duration will allow me to achieve a much higher dynamic compression ratio for more power throughout the midrange and early in the powerband. I have upgraded the valve springs to reduce valve float but i can not imagine the rb26 head and valvetrain in good working order even with stock cams having any problems revving to 8000 rpm. I would love some opinions of the more experinced gtr guys here as this is newish territory for me. Previously a v8 guy and a mild rb25 with 300kw was the most i have delved into the rb world myself so now its time to step things up a bit. Thanks in advance and looking forward to being more active in the community, may even start a build thread when the assembly starts.
