Going for 500+hp, need advice

You don’t need oil restrictors in garret turbos 

and the power figures and etc I quoted are from experience and not from reading stuff on the internet

There is a built in restrictor on the GT2860/GT2859, but there's some asterisks there. If you run more oil pressure than stock, if you change the feed lines for some reason to a larger diameter, variables like that can require you to run an additional restrictor.

Buying these cars requires a type of mindset, at times I think buying any JDM requires some form of slight mental retardation.

I'll use myself as an example, buys a $5k R33, spends over $70k on it (I have a full spreadsheet of every part/machining/fab work that has been done/bought for the car. That list does not include anything maintenance related and the endless workshop hours, dyno hire, etc.) over the past 9.5 years.

There are days I regret it and wish I bought a M3, there are days I marvel at the beauty of the heap of shit.

Lol so true

I hear some of you say its a no brainer going single turbo but my reason for upgrading the twins is because its cheaper, easier to do (?) and because it looks stock and therefore I wont have any problems at the MOT wich is very strict here.

On the other hand it would probably be better going single because of better power, sound and less problems overall with heat ect..

If I were to go single, what is the best turbo kit for r34 gtr out there? 

[Duncan]

Personal opinion but I think the days of putting singles on GTRs is over for most people. They have clearly become a classic/collector's car rather than something where you are looking for a very fast daily driver (plus, most of the GTRs with singles live in a garage on stands anyway). 

A set of old fashioned -7 or -9 twins and keeping the standard intake piping as mush as possible is they appropriate way these days.

I find it hard to believe that there are GTRs out there with the standard turbos still on. I cannot imagine how anyone could have put up with them for this long.

Agreed!  Its also the risk of the ceramic wheels that drive the need to change

Either precision 6466 T4 .84/1.00, gtx3582 gen 2 .83 or g35-900 .83. Still a decent size turbo with good response and make power. These are the kits below come with everything you need to do a swap

I still have them standard ECU standard engine (restrictor removed from the bleed valve thingy). I even run (barely) Yellow Jackets

[GTSBoy]

Yeah, well, I should avoid chucking stones inside my glass house. Standard turbo still on my Neo, for example. But it's not quite the same level of suck.

Actually, it probably is. But it's not a GTR. A GTR deserve a lot more turbo.

I think it's the other way around. The Neo is a better motor, and the turbos that come on stock way way way way way way way too small. It's not as though the Neo has a 270kw turbo setup on there from the factory like the 26 does 😛

RWD R32 with a lot of power is just wheelspin city, if it is also set up to go around corners.

-7s are the r34 n1 turbos (and the nismo r1) they are direct bolt on and will make 500hp at the wheels with e85 and cams 

-9s are the same as hks gtss turbos are will bolt also bolt directly on and make the same power as the -7 (some believe with slightly better response)

the -5 is slightly smaller then the hks 2530 and are a lot more laggy then the -7/-9s, they require different oil drains that are easily sourced which then makes them a bolt on turbo and can make more like 600hp at the wheels if the rest of the set up is done right  

So the -7 is the same as the original r34 gtr turbos just with bigger upgraded turbine wheels and ball bearing? Does that mean I can re-use the oil and water lines/hoses and banjo bolts?

Not vanilla. N1 turbos.

Yes they all bolt straight over

wallah you want a Nistune? pull out your ECU and we'll get it done through my trade account

My R33 had standard turbos when the engine was pulled as a part of the chassis refresh. I didn't trust them though and never drove the car with them.

The -7s are R34 N1 turbos, but R34 N1 turbo covers something like 3 distinct part numbers. The -7s I believe correspond to 14411-AA403. If you ask Nismo they believe that the -7 spec turbos have worse transient response if you're aiming for relatively low power, hence why they released the R3 turbo kit recently which is closer to the earlier AA401/AA402 turbos:

Their 450 PS claim includes a healthy derate from what the turbos are capable of pushed to the limit, it's also using an engine dyno:

I actually have a broken Nistuned ECU. But yes need to Nistune. Also Need to throw on the R34 N1 turbos and oil cooler, then I'll contact you hehe

[The Skyline Guy]

Just to be sure before I buy, can someone verify that this is the right -7 that I need: https://www.ebay.com/itm/303055603645

Will 340lph fuel pump work for 500+ crank hp, like this AEM one: https://www.ebay.com/itm/323980413969?epid=1217828034&hash=item4b6ebccc11:g:mH4AAOSwnxxdzcru Will this just mount right in the tank or do I need some different hoses, connections ect?

[r32-25t]

That’s the right part number but that listing looks dodgey as f**k
