Racing VQ
Nissan's versatile VQ series engines were initially never intended for racing applications. yet the powerplants ended up becoming a mainstay, replacing the RB series motors in the JGTC R34 GTRs:

Infinity Pro Series
The inaugural season of the Infiniti Pro Series began July 7, 2002, at Kansas Speedway and culminated with the Sept. 14 season finale at Texas Motor Speedway.
The Infiniti Pro Series is a step-up category to the Indy Car Series, the pinnacle of America’s racing scene. Fourteen Infinity Pro Series races are scheduled to be held this season, 10 on ovals, 3 road course and 1 street course. The race cars are all Italian Dallara chassis “one make” cars. No chassis modification, including changes to the wing angle or shock absorbers, is permitted.
The teams are permitted to change only the air pressures, vehicle height, and toe and camber angles. The engine is the North American spec Nissan Infiniti Q45 V8 production engine downsized to 3.5 liters. This has been slightly reworked for racing and outputs around 450 horsepower. Infiniti completely controls all the engines, and all same spec units are supplied to the teams. This means that all the racecars have the same performance. The main aim of this series is to provide an environment conducive for young drivers to learn to do battle on the oval circuit. The Pro Series race is 100 miles, with no pit stops.

GREAT THREAD
I have 2 questions for you bonzelite. How long does the engine of a tuned to aproximately 500hp GT-R lasts(miles or kilometers). And how many miles per galon.
And a third one is: How do you know so much about cars
. I'm still learning and hope one day will know as much as you .

. I'm still learning and hope one day will know as much as you .a 500hp-tuned GTR can last as long as a stock one if you maintain it regularly and do not thrash it. that is actually a mild street tune: in general, to get a GTR to 500hp will require upgraded (larger) turbines, a larger FMIC, larger duty cycle injectors/FPR and a subsequent remapping of the fuel system; higher lift cams. a larger downpipe and exhaust would be added as well. to keep the engine "comfortable" with these new conditions, you'd do well to add an oil and tranny cooler, maybe even convert to a dry sump as well.
anyway, the RB has never really been known for it's wonderful gas mileage, but you can drive that on the street with pump gas, and would run better on race gas (100 octane). if you follow scheduled fluid and filter changes and treat the car with respect, you can drive the 500hp GTR for as long as a stock one. however, it is the way you drive and maintain that affects engine longevity: if you drag race it weekly, it will be subject to harsh conditions very quickly --you could blow the engine or drop the tranny on the tarmac. conversely, you baby the engine and tranny --it will last years, maybe decades before rebuilding.
to answer the second question:
i have a basic understanding of how a car functions, have worked on my own car, with a pinch of automotive engineering and history knowledge. and based on that, i can find ever more obscure things that relate to the basics of what i know, yet are not really quite known until i dig deeper and farther. so i learn by studying the hobby and craft because i love it. and it brings me pleasure to learn and share it with everyone, for those who will learn with me.

tombstone frame
today, engine designers can do such extensive assemblies in CAD that they can see how everything will fit together before it is made. for design, Nissan and "Westcoast" (based in Anaheim, Calif., designers and manufacturers of specialty components, mainly for the internal combustion engine industry --Nissan contracts with this company for production of its racing engine blocks) use Pro/Engineer CAD software and Pro/Manufacture CAM software from Parametric Technology Corp. of Waltham, Mass.
before an actual engine block can be "machined," a rough casting of the block is made at the foundry. this rough cut stage is a basic block design that can be altered in many ways depending upon the application. this is the "diamond in the rough" stage. therefore, to machine cut or "dial in" this rough block, actual cutting tools and/or "fixtures" must be designed along with the engine block itself.
the engineers, then, use the same CAD program for the design of the cutting fixtures as the engine block, and the fixture models are then sent to the "numerical control programming department," where employees write the programs that will dictate the machine's moves as it machines the castings. this happens in parallel with the block casting process.
once the blocks arrive for cutting, the fixtures that will shave down the metal, drill holes, create the overall character and functional design of the engine, are assembled to a framework that surrounds the bare uncut engine block. this framing for the fixtures, a sort of "scaffolding," is called a "tombstone frame."
because engineers design the fixtures in their 3-D CAD programs, they can create layout designs that ensure as many fixtures as possible can be mounted on the tombstone frame at once. this process affords ease of design, ease of change of design, and quick turnaround time for high performance modifications to a cast engine block.

Stagea
--on a Skyline platform but not a Skyine: the Stagea.
A wagon based on the R33/R34 platform was released in September 1996, called the Stagea. It had a different body style than the R33 and R34 and (with the exception of the RS FOUR variant) was only available with an automatic transmission. A common modification on the Stagea is to fit it with an R34 skyline front, in effect making a 4 door R34 wagon. Unlike the R33 Skyline, the Stagea is the only four wheel drive manual transmission Nissan with the RB25DET engine. Presumably, a 5 speed 4WD Skyline equipped with an RB25DET would have been too close in performance to the much more expensive GT-R. There was also a Stagea releasd with full GT-R running gear, the RB26DETT engine, and manual transmission.
