240rwkw from a 3071 is not surprising, Garretts are a mixed bag to begin with.. Always hit and miss on results.

A Hit 3071 is 290rwkw, a miss is 240rwkw. Hit 3076 300rwkw, miss 270rwkw.

I want to know myself! One way or another it's pretty sweet, and no doubt the 4deg retarded camgear has a fair bit to do with it though the manifolds can't be hurting, and the turbo clearly needs to efficiently flow up there.

Simon - do you know of anyone with cams and a T67, or do you have any plans to do it yourself?

I honestly have to say my opinion is the combination of the 6boost and a healthy motor.

Simons motor does not show any signs of sloppy valve springs which I think are the main contender in limiting an RBs power development.

I ditched my RB for this exact reason, I knew it was fine as a factory motor but also knew it was anyones guess how it would handle over 300rwkw. I am, however, dubious of the benefit of the forward facing plenum.. Yet wont knock it either.

The different size/length runners make a reasonable amount of difference with this kind of thing and sloppy valve springs no doubt come into it too - but peak power for a factory RB25 by definition of Nissan is 6400rpm, and a car with stock manifolds and pretty much any turbo will make peak power around those rpm. Thats where mine makes its peak power, as with gazillions of others I have seen - I am pretty sure a T67 will be no different.

You're going to need some pretty serious mods to get a 1JZ revving like that ;)

OH YEAH?!?!??!!?!11!! Dont make me huff and puff and blow your house down!

Kidding, well see Mr Duracell lithium ultra :thumbsup:

I have a few concepts Im toying with at the moment, yet my primary objective is to get this thing on the track as quickly and as cheaply as possible WITHOUT the use of the factory twins.

No doubt the FFP has changed the motors dynamic VE, yet I am dubious to what extent and effect. Yet I honestly am no expert in this sense either.. I just HAVE to point out a healthy motor to begin with, thats a major factor in my eyes.

This is the only graph I have seen with a Kinugawa T67-25g with cams;

Blue = Stock cams

Red = Camtech drop in cams

No plans for cams, I really don't see the need... Turbo appears to be maxing itself out and I have more than enough power throughout the rev range :)

yeh me too :) where you getting yours tuned? ill most likely be taking mine to STATUS.

i was going to status, but ive chosen a different tuner, the guy im going to was recomended to me by a friend, he tunes thier GTR track cars, and also an aus distributor of KAMAK turbos.

Nice, was that on pump gas? The factory setup is pretty impressive, going by that lot.

    • Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.
    • Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.
    • It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!
    • Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
    • The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
