J's Racing S2000 on the touge


How does the 1st generation of J's Racing Honda S2000 handle on the touge? It's designed to be a daily driver car with stereo and navigation system. Keiichi Tsuchiya is really impressed with cornering abilities of J's s2k. When he's suspiciously quiet while driving any car, that only means he really enjoys the drive. Taniguchi and Orido are also impressed with J's s2k, is it better than Amuse S2k?
J's Racing Honda S2000 specifications:
Engine - F20C moded by J's racing - 280 horsepowers
ECU - J's Racing
Headers - Mugen
Exhaust - J's Racing
Transmission - stock
LSD - Cusco RS
Final drive - 4.777
Dampers - J's Racing coilovers

MINE'S Nissan 370Z


Keiichi Tsuchiya testing JDM Mine's Nissan 370Z at Fuji Speedway track in December 2008, setting a time 2:04:610.

Toyota AE86 vs Honda EK9


One of legendary videos, battle between AE86 and EK9. As soon as Keiichi Tsuchiya in AE86 overtakes EK9, he starts drifting and making fun of opponent. EK9 has more power and with it advantage on straight line, but AE86 handles better in the corners. What's your opinion? Has EK9 wrong suspension setup for this track? Would the result be different if Tsuchiya would drive an EK9?

Sweden: Bjorks Toyota Supra with 800hp


Very nice videos of Bjorks Toyota Supra from Sweden with single turbo. Having fun on the track, showing off on the parking, at the end of first movie; video showing acceleration from 100 Kph to top speed: 340 Kph! 100-100Kph in under 5 seconds, that's just crazy... Although it's not JDM styled, I wouldn't mind at all owning it:)

HKS Skyline GT-R R34


Keiichi Tsuchiya testing 650 hp HKS Skyline GT-R R34.
HKS Skyline R34 has variable valve timing control (VVT) on a turbo engine. VVT is installed for keeping the low rev torque and still keeping the maximum power outcome at high revs. Loss of low rev torque is often when stock turbine is replaced with bigger one. HKS GT-R also has HKS custom forged crank and pistons..
What about adjustable valve system in exhaust, which controls the exhaust noise! The car is oriented to be the ultimate street GT-R. In a video it runs on street tires and not the best setup for that track, I think that's why it's such a difference in best lap time between HKS (1:03:xx) and MINE'S (0:59:xx) Skyline GT-R.

Difference in power measures bhp whp kw


Many people don't know the difference in some power measures like bhp, kw, whp, hp etc so here's my explanation:
Horsepower (hp) is just a unit used to measure power of engines. Power = Work / Time. If we believe James Watt, 1hp is power needed to lift 550 pounds one foot in 1 second. So 1hp = 550 pounds x 1 foot / 1 sec.
Watts (w) is a unit used to measure power (joules per second). 1000w (1kw) is equal to 1.36 hp in the metric system which is often used.
Power on engine's crankshaft is bigger than power on wheels because pure power of engine's output has some loses in gearbox, differential, water pump, muffled exhaust system and other auxiliary components of an engine.
Brake horsepowers (bhp) is power on engine's crankshaft with no loses on other engine components. Brake refers to a device that holds engine's rpms to hold at desired value.
Wheel horsepowers (whp) is a effective and true measure for real power output because it's measured directly on wheels with all the loses in gearbox and other components. It's a measure of horsepowers that come directly on the wheels and ground. It measures on a dyno.
What's the number difference between whp and bhp? It's different in every car, some of them have more loses of power and some of them less. But usually we add 10-20% of power to get brake horsepowers from wheel horsepowers.

JDM Japan police cars pictures


Police officers in Japan seem to have a dream job. Who wouldn't love to drive around Subaru WRX Sti, Honda NSX, Nissan R33 or R34 Skyline? Ignoring that you have to chase bad guys and do some paper job, being a police patrol officer in Japan really is a dream job.

Engine swapping


You tuned up your engine, still not enough power.
For example you tuned your b16a2 engine in Honda EG6, it has 200+ horsepower, it's faster than your friend with his stock K20 in a Type R. But K20 has a lot more potential for tuning, it has a 200hp and more torque in a start and a bigger engine. Your friend will only change exhaust system and tune his ECU and he will again be faster than you.
Engine swap tuners economic problem is that it costs a lot of money right in a start, when originally mounted engine can be tuned step by step, not much money at once.
Engine swap isn't just an engine, it's usually also swap of transmission, ECU, engine mounts accessories, drivetrain and much more. Plus money for mechanic to mount an engine and rest of stuff in your car.
Once you're there, all the hard work is forgotten and nothing can compare with happiness when reving up your monster and feel the power of your completed work.

NA tuning - engine modifications


Now that we've changed complete exhaust and intake system and we still don't have enough power, now it's engine's inside turn.
Increasing compression - change pistons with high-compression ones or replace oem head gasket with a thiner one.
Cams - OEM cams don't have the optimum aggression. They are classified by stages of aggression: stage 1, stage 2... Be sure you choose the right ones for your goals. Some of them are better for mid-end range, some of them give more power, some more torque...
ECU optimization- it's necessary for tuned cars. Cam timing, ignition, how much fuel goes to the engine, if there's too less fuel going in, power of car won't be optimized and you can hurt your engine for that. If power is too big for OEM injectors and fuel pump, replacing them with bigger ones is a must. ECU tuning should only be done by professional tuner on a dyno. If you don't know how to do it, don't try to do it yourself, you can make more damage than good stuff.
Valves + valve springs: Put in some sport aftermarket valves and springs, especially when you increase redline of rpms on ECU tuning. OEM valve springs probably won't last long when rpm redline is changed to 1000revs higher than stock and a big damage can be done to an engine.
Engine head - Port polish a cylinder head increases compression, it optimizes power and turns production engine into a racing one.
That's about it for NA tuning, don't forget to optimize transmission: lighter sport flywheel, stronger clutch and LSD in your gearbox for optimized performance.
Don't forget: This are just some basics to imagine how things go in tuning, don't tune if you aren't sure how things work and what will your modification exactly does to your car;)

Header difference in performance 4-1 or 4-2-1


It's a performance difference between headers. (4-cylinder engine) Basically...
Numbers (4-1, 4-2-1) means how pipes join together; 4 directly in 1, or 4 to 2 to 1.
4-1 pipe header brings more power in high revs, that gives better acceleration on a straight line and bigger max power, but you will have to push up your car on high revs all the time to notice a difference.
4-2-1 pipe header brings more power through all the revs area, more practical for everyday use, gives more torque and power in low to mid rev area.
Which one would you choose? It won't bring much power on a complete stock car, for noticeable difference get sport cat-back for a start and start tuning your monster :)

NA tuning - Basics


Tuning is adjusting, modding and replacing components of car to improve it's handling and performance.
Tuning should be done only on healthy engine, unless your budget is too big... first take care of engine's "health", or it will only get worse with further tuning.
NA literally means Naturally Aspirated, pressure of air going to the engine is atmospheric, that means no turbo or compressor.
Where to start NA tuning?
-Cat-back - Improving complete sport exhaust system so the engine can "breathe" is somehow a basic for further tuning of a car. Fi of exhaust pipe should be bigger than stock because we want to increase power and more power means more air going through the exhaust.
-Header - right choice of header is more crucial than cat-back itself. You choose between 4-2-1 and 4-1 header (4 cylinder engines)
- de-cat pipe - It's an empty pipe to replace catalyst, which combines together cat-back and header. There are some loses in catalyst due to cleaning filters inside, de-cat pipe saves it. Alternative solution of de-cat pipe for Greenpeace members is sports catalyst. But if you are a Greenpeace member, you probably drive around in a bike, so no tuning needed for you:)
(Toda exhaust system)

- Air intake system - You can change air filter in airbox for some more breathable sport filter, bigger airbox, SRI or CAI intake. SRI (short ram intake) is mounted directly on throttlebody, it only speeds up reaction of engine, doesn't increase power, that's why I recommend CAI (cold air intake).

It's a pipe with air filter on the end of it from throttlebody to a front bumper usually, it intakes cold air, which gives more power to the engine, than warm air under the hood from SRI.
Than u change OEM intake manifold and Throttlebody for bigger sport ones, so more air can come to the engine, it gives more power and torque.
(Skunk2 intake manifold)

(Blox Throttlebody)

That's it for a start of NA tuning, next level is direct intervention of engine, cams, valves, pistons, ECU re-programing, valve springs... we'll get to there soon ;)
Don't forget, more power means bigger speed. Don't just tune your engine and maximize your power output, be sure you are safe, don't forget to upgrade your brakes.
Not enough? Check out some basics of NA modifications directly on engine.

Mine's R34 at Tsukuba Track


MINE'S is a auto tuning company in Yokosuka, Japan. They were one of the first Japan tuning companies that started selling re-maped ECU systems for Japan sport cars.
Their most famous products are tuned Nissans GT-R. Although the newest Nissan R35 GT was supposed to be untuneable because of locked ECU, Mine's started selling their tuned version of it with 100 more horsepowers only a week after R35 was available on market.
2002 MINE's R34 Skyline GT-R had 600ps, Best Motoring recorded a lap time of 57.7 seconds at Tsukuba with it. That's about 6 seconds faster than McLaren F1 on this track
Mine's stays away of the decorative styling part of modifying cars, they only focus on cars performance. Mine's founder Michizo Niikura answered on question in Best Motoring interview in 2002 why they left stock airboxes on R34 "We basically leave it up to each costumer how to modify some parts. If we try to do too many things, we will lose focus as a company" (I posted that video in another article) Simple and effective :)
This are videos of MINE'S R34 on Tsukuba track, drivers are Keiichi DK Tsuchiya and Tarzan Yamada, which drove best time of 57.7sec
