What about fitting a Toyota 2GR FE engine in our cars?

I'm surprised no one has yet tried to fit this V6 3.5L engine in an NSX?
https://en.wikipedia.org/wiki/Toyota_GR_engine
This version of the engine is used in the Lotus Exige S in various states of tune with up to 430 hp through a Harrock compressor.
I see three reasons for using this engine:
- It must be readily available at least in the US
- It's transversely mounted with a 6 speed gearbox
- It comes with cats making it road legal.

Moreover it can be tuned further with parts from Komo-Tec: https://komo-tec.com/Shop/en/Exige/...-EX460-Upgrade-105hp-80Nm-Exige-S-V6-350.html
 
The J-Series is also readily available in the US though. You can also get a 6 speed manual from the Acura CL-S/TL-S/TL. I'm not sure the US got a 6 speed manual 2GR FE in the USA, unless it's coming from a Lotus Evora which I imagine won't be cheap.

Edit:
Looks like the Lotus uses the EA60 gear box from a Toyota Auris Diesel sold in Japan. Would be more expensive than the Honda 6 Speed, but probably not unreasonably expensive to import.

Interesting input!
I've looked around for a wrecked Lotus Exige V6 but without much success.
In the end the Lotus is maybe the true successor to our beloved NSX?
I need to drive one to determine if it's really true.
 
I came across this article about the latest Lotus Exige 410 that's compared to the Porsche GT3 RS.
https://www.pistonheads.com/features/ph-features/porsche-911-gt3-rs-vs-lotus-exige-sport-410/39144
Of course the comparaison is not fair given the Porsche is twice the price but if you read in between the lines the author (despite beeing british...) is not that enthusiastic about the top of the line Lotus.
I've been racing against a 991 GT3 and the difference in lap time was only 1 second in favor of the GT3.
Having beeing on board of the Porsche, I would say that the driver was no worse than myself so I hope that with a few more tweaks to the NSX such as a GTC 300 racing wing ( http://aprperformance.com/racing-product/gtc-300-adjustable-wings) and non-compliant rear beam bushing mods might get me there?

For a new engine, that seems a reasonable price. I do note in the description at the bottom of the page the reference to 'without charger'. If charger means alternator, that is not a significant additional cost. If charger means supercharger then that is a more significant additional cost. If somebody were looking for a replacement option for a damaged C30 / C32, the cost of the Komo-tec engine plus supercharger plus engine management plus everything to get it to fit likely makes it non price competitive as a simple engine replacement, certainly compared t a J swap using a salvage J engine or even a C30 / C32 rebuild from someone like SOS.

If you are considering this as an alternative to a C30 / C32 rebuild to accommodate something like a twin turbo installation which means you are into new engine management and other stuff anyway, then this could be pretty attractive path to follow (providing you can get the peg to even fit in the hole). It does have the advantage that you are dealing with a more current and common engine with good parts availability and more technical support for future performance developments.

Given that we already have a vendor who has done the footwork for the J series engine swap, my opinion is that the J will likely be the future go-to substitution engine on this side of the Atlantic. Despite its rather pedestrian source (God - its a mini van engine!) it does seem capable of some very respectable power outputs in turbo form. Its configuration and lower RPM capability guarantees that it will never sound like a C30 / C32. At 4000 + RPM the J in my Honda Pilot makes a sound that suggests that it is not really happy doing this and lets get it over with, quickly please. 5000+ RPM on the C32B is sans effort with a big smile.
