Power matching on import models

[Alex_GT]

Hi guys, how much does it cost to bring the power of an import model to the same as the UK model? Is there a kit you can buy like the BPU that has all the components required?

Yep - all you have to do is buy an import TT. They have the same power. The 280PS/276bhp thing is not the case. They are also ~325bhp in stock form.

 

Then, should you wish, you can BPU it from there and achieve 380-400bhp, just as you would with a UK spec.

Very cheap, just get a fat friend to sit in the passenger seat of your j-spec TT.

Are you certain this is true? I thought it was illegal in Japan to build a car with more than 276hp?

It's been known for years mate jap Supras are more than 276 stock. On paper seemingly there was a gentlemans agreement years ago between Nissan and Toyota at the time to cap it at 276 but in reality it never happened.

Just search for '280ps Gentleman's Agreement' or similar. That'll answer your question for you. Here is an excerpt from an article too:

 

Since 1989, Japanese automakers have all endorsed—at least on paper—a kind of gentlemen's agreement that limited their advertised horsepower to 276 on domestically produced vehicles. Their primary goal was to avoid a horsepower war in a country where the maximum speed limit is 62 mph. But in October, Honda officially broke the agreement at its Legend (Acura RL in the U.S.) press conference when it unveiled the model's 300-hp, 3.5-liter V-6.

 

For years, it's been presumed that once an automaker stuck out its neck and ignored the 276-hp mark, the rest would quickly follow. And judging by what's in the Japanese production pipeline, it looks as if the conventional wisdom was correct. Coming on the heels of that new Acura RL will be the Lexus RX400h with an estimated 300 horsepower, and then the flood gates open—Mazda will introduce a 300-hp two-seat RX-7, Acura will again cross the line with a new NSX with at least 400 horses, and Toyota will mark its territory with the supercar on page 36.

 

Japanese engine designers, however, will readily concede that the country's manufacturers have been building cars with more than 276 horsepower. It's just that none of the automakers wanted to officially break the agreement. It's no secret that Mitsubishi Lancer Evos, Subaru Impreza WRXs, and Nissan 300ZX twin-turbos have been in violation of the agreement for years, but at least in Japan, they all claimed to have 276 horsepower. The false advertising was ignored for the sake of harmony. Not anymore.

 

There are also various dyno graphs of totally stock 2JZ-GTE engines from J-Spec Supras which are all in the region of 320bhp.

Just my failed attempt at a little humour

 

A stock UK spec Supra has similar hp to a stock j-spec Supra (around 320hp) but they are heavier and the turbos are slower spooling.
