9.6:1 would be great.

Have been speaking with Matt today. Looks like I will be staying with the Nistune set up. Unless I have problems. Thanks for the input guy's.

I have been looking at the oil restrictor threads on here and from what I can make out I need to block off the rear feed in the block and put a 1.5mm in the front one. Car is mainly for street use with the odd track day. Or would I be better off with 2x 1mm feeds or 2 x 1.25mm?

Well your call but 2x 1.0mm gives slightly less flow than 1 x 1.5 but has the security of two feeds instead of one (in the hopefully unlikely event that one gets blocked). On the other hand 2 x 1.25 flow a LOT more than one 1.5 (don't forget you can buy them from me unless you have a better source).

Well been a while since I've done anything else. Its going to be a long build. Pick up arp head studs tomorrow. I have a new inlet and exhaust gasket now waiting. Machine shop is making slow process but not worried as I told them I don't want it back until about May June. Have been told that the Nistune won't be able to handle the setup as will have to much air flow for the airflow meter. Will have problems with it stalling. Waiting for Matt from Nistune to get back to me. Worst case I'm up for a new ecu. Any suggestions?

Adaptronic.

Whilst Adaptronic or any other aftermarket ECU are perfectly valid suggestions, it is not true that you can't use Nistune because of having too much air flow for the AFM. You can put a Ford Lightning AFM onto it - Nstune can handle it. You can put an R35 GTR AFM's sensor into a 6" pipe and measure 3000HP worth of air if you want to. There's not really any limits from that point of view. The main limit with Nistune is lack of extra functions and sometimes the problems where the stock ECU's self protection behaviours get in the way of tuning more extreme engines. Sometimes there are ways around them, and sometimes there are not. Sometimes the ways around those problems get found before, during or after your build/tune. Sometimes they don't.

I was in the same boat last year. Loved the nistune just the AFM was a little annoying with my intake setup as I am running a 4" pipe. Talk to Matt about a mob over in the U.S that does specialty AFM's. It was what I was going to run as it was perfect for my situation and Matt has already integrated them into nistune.

I have a topic on here about it, search and you shall find.

      We're arguing semantics. I am saying 45 accel and a 55 deccel ramp are "2 ways". Even a 45 degree ramp and an 89 degree ramp is "2 ways", because it is literally... two ways. The cusco 55/30 ramp is a 2 way. It's two ways. I get it though - in normal nomenclature a "2 way" would be 45/45 or 55/55 or 60/60 i.e the same locking in both directions. And something like 45/65 would be considered "1.5 way". I would then say if we're getting into the nitty gritty then every locking diff is a "2 way" diff and we should not speak in 1.5, or 2 ways but ramp angles instead. Which ofc if one of those ramp angles is 90deg, that side is not doing any locking. :p So Nismo don't obviously sell 3 things. The fact of the matter that they only sell two items really goes to show that there's a 2 way and a "1,5 way" which is really a 1 way. I believe the actual lockup for the 'adjustability' of the GT pro is really just setting preload for when the ramps actually start locking up. It's not changing how much 'wayness' there is. It is (somehow) horribly explained. People just buy whatever diff and go "locks up good bruh" and that's what ends up on socials forever.

      No, you're wrong, and you've always been wrong about this. The Nismo has 2 sets of openings. One is a real 2-way, and the other is a 1-way. There is no 1.5-way possible with the ramps that they offer. A real 1.5-way does exist. That Cusco stuff I posted is a prime example. If the forward drive ramps are, say 55°, and the overrun ramps are, say, 30°, then you will get about half as much LSD effect on overrun than you do on drive. It is real, it realy works. OK, you're slightly right. The Nismo has 55° and 45° ramps on the 2-way, so it does offer less LSD effect on overrun. But, I think that just means that they've (probably) sensibly established that you do not want actually equal LSD effect on overrun. You just want "quite a lot, but not quite as much as the drive LSD effect".
