Dropped off the bottom end today to the machine shop. Getting hot tank acid wash bored honed tunnel squared to deck crank nitrated oil galleries cleaned grub screws fitted to crank. Crank modified for 25 oil pump ballanced and a few other things done.

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.

    • Thank you, 100% the intent. New coils were due and the 17" sixers look/feel loads better than the stock wheels. The aero options are so spot on.   Thanks for the warm welcome, all!
    • 98 r34 gtt Been rocking my latest setup and car running like never before. Have put a good 200 miles on it since all the latest changes and additions. everything is dialed in and have been driving it a bunch.   However, all a sudden last weekend as soon as I pushed throttle passed 4k and the engine stumbles, (slow or fast acceleration) hesitates and doesn’t go above 4100 or so, like a misfire. Everything else seems fine. I had a “good” set of coil packs that I removed from car when I first got it when I changed them over to new coils. I swapped out current ones for those, but no change. I also changed the plugs, no change. Seems to rev over 4 when out of gear with no load just fine no “misfire”, but as soon as its in gear with a load of any kind, it “misfires” as soon as rpm drop back below 4 k it runs perfectly, smooth, starts, restarts and drives fine as long as I keep it below 4 k while in gear. All readings look fine, no CEL   Any idea as to what could all a sudden cause an issue when pushing rpms passed 4 k?
    • When you say your cams are 272/262 is that 272in and 262ex?
    • 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.
