Most people here would recommend the Quaife front diff over the nismo, as its a helical type diff instead of mechanical plates, helps with understeer under load. Also my diff guy doesn't like to install mechanical fronts as too much of the diff housing needs to be ground down to make them fit apparently

Additionally, note that for the gtx turbos, they aren't a bolt in affair, to get mine i needed to find a rear housing to suit and then get a front housing machined. As was mentioned in the first page, you should probably be able to get a turbo shop to do that using tx 2863's into your existing turbo housings. why not 2860's? because you cant machine something to be smaller than it already is.

You mean you'll get more lag and shift the mid range higher up the RPM..

Longer duration cams are not the answer to getting better response or making better mid range.. Yes you will make more torque yes you'll make more power but not where you want it.. and that's nice and early.

I have 272 by 10.8 cams on a 2.6 with -9 turbos and have full boost 21psi by 3800rpm on 98

put some smaller cams in you will get even better response.. and welcome back lol.. you went missing for a while

Check my build thread for very detailed Nismo install instructions including highlighted areas where to grind. It was not significant by any means.

Regarding the clutch diff vs helical...I think the nismo 1.5 instructions references that it is a lightly set clutch style...not crazy deceleration lockup (but I haven't driven mine yet). I'll let you know when I drive it.

I would also have chosen quaife but I would have had to become a dealer in the USA and buy 10 of them to get one!

Also nismo came with the bearings and seals. I don't think other ones do. (Tomei, quaife, etc).

Also don't forget you will be buying / ordering shims. The setup took a bit of time for me. I had to make 2 shims.

I understand there will be lag, but there is acceptable lag and a dyno graph that looks like a cliff face. Nothing and everything for a split second.

Dynos gives u info in one gear and WOT.

On the street you never load up 4th at 2000 rpm at WOT and wait for boost. Real world is different to a dyno.

Also the EFR are literally the fastest responding turbos on the market right now. Geoff at full race made 704whp through the 8374 EFR on a stock bottom 2.6 with lots of headwork on E85 through a cat.

    • Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand. 
    • Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!
    • I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
