But nah dudebroman the r34 is wayy quicker my mandude
Convince me not to get an R34

The aero is different. The R32 has severe front lift issues at speed, this is well documented by engineer interviews. The drag coefficient is much higher as well, a bigger wing isn't going to solve the issue of how the R32 exposes so much tire in the frontal aspect. The R32 lacks a front and rear diffuser too which means downforce in general is lacking. The R32 has a much worse weight distribution. The gas tank, front-mounted battery, and a whole host of other things is responsible for this.
The R32 GT-R also has far worse chassis rigidity. At minimum you need a trunk bar, two strut tower bars, chassis spot welding, and a whole host of other reinforcing bars to catch up to the R34 in chassis rigidity. Otherwise mid-corner bumps are going to cost you quite a bit of speed compared to an R34.
This isn't even going into suspension tuning or anything else. If you read some books on the Skyline GT-R you'll see that the power delta between the R32 and R34 isn't huge but the difference in how well the R34 puts power down is enormous. People just have no background in engineering and don't understand that there's more to a car than the engine. This isn't even getting into the differences in ATTESA, HICAS, and ECU.
Don't get me wrong, you can absolutely get an R32 GT-R upgraded to the point that it will be a better car, but the amount of time and knowledge that it takes to do this in a non-halfassed method means buying an R34 GT-R from the start is arguably cheaper.
The problem for me at least is that I don't see a well-engineered single conversion kit for the RB26. I would rather just trust that Garrett has actually done engineering work on their side and bolt on two -9s with SiN ball bearings and do the bare minimum of fucking with the engine as possible.
With HKS VCAM you'll be at 1 bar before 3000 RPM: rhdjapan.com

Most of the world drives on the right side of the road. Don't assume he lives in Burgerland because he drives right

>The drag coefficient is much higher as well
The drag coefficient may be higher, but the frontal area is lower, making it more aerodynamic.
But yes. They are completely different cars. They share very few parts in common and they are on a different chassis.

Yeah, I'm not seeing one either but I know it's possible. You just have to make it yourself. Get a local racing mechanic to do your custom fab, which will cost less than a kit does.
What I would actually do is use the stock exhaust headers and add a V shaped header that connects them to a twin scroll 7163 instead of using a completely new header. Would probably cost $200-$300 for a good custom fab job for it and is an idiot proof design. Then another of that for your downpipe. Simple as well (besides your gasket, turbo oil piping, etc, obviously, but that's are off the shelf stuff.. or if you really want to get an aluminum oil line and bend it yourself instead of using something flexible)

Again, I'm being REALLY conservative. I like conservative, street tunes. Like a clean, modern car, instead of that blow-up-in-25km-or-when-the-weather-changes shit. With a 7163, you'd likely be more around 1.7bar at 3000rpm if you're using race gas and such, and 1 bar would happen a few hundred rpm earlier.
There are NO aftermarket turbos that spool up as quickly and have as good of aerodynamics for any given size. Nor ones that are slightly smaller.
Think of a 7163 as a turbo which compressor is almost as efficient and flows almost as well as a GT38, yet it's the size of a GT28, yet it flows exhaust almost like a GT38, yet it spools up quicker and earlier than a GT28. You're comparing modern tech to 20 year old tech.

I'm pretty sure that even compensated for area the R32 is less aerodynamic.

I would rather not fuck with the engine to that extent. Less is more. Parallel twins is retarded on an I6 but that's what Nissan did and living with that is just part of it. There are a lot of engineering considerations to make here and unknown unknowns.
This kit is expressly designed for the RB26 but right away you can see a possible case where mods can interact negatively. This manifold is designed for the stock intake plenum which is lean on cylinder 6. If you used the Nismo GT Plenum which is designed to balance airflow to all cylinders, cylinder 6 would end up rich.

That's nice, but even the Garrett 2859R-9 with stock twins will have turbo shuffle at low RPMs if you don't replace some of the stock piping.
Garrett is also updating the -9s with ceramic ball bearings instead of the metal ball bearings used before. So they will spool even faster than the HKS GTIII SS which has fucking journal bearings.
I'm all for people pushing the envelope, but for a personal street car I would say you want to mod as little as possible and avoid messing with things you don't understand. You can easily mod a car to be worse than it was before.

my evo x mr cost me less and is faster and better in every mesurable way
just let it go guys

Yep I saw that header. People are retarded.
It's designed to put the turbo up and and up front so you have room for a large compressor in front of the wheel well. That's for 8374 and shit.
That's why, you know, I said you use the stock twin turbo headers which balance 3 cylinders, and just add a joiner manifold to mate them to a twin scroll rather than two separate turbos.
Very simple, elegant solution.
But obviously with any major mods, you're going to need to remap.

Only attention whores do that.
Literally only idiots go through a drive through as well. It's always faster to go inside. Always.
