VH45DE (all versions from 90-96 model years):
4.5L all aluminum V8 with 4 valves per cylinder.
hemispherical combustion chambers.(!)
Sodium filled exhaust valves (!)
VVT
Molybdenum coated cylinder walls.
6 bolt main bearings w/ a girdle.(!!!)
As a rule of thumb, the first 18 months of production must have been close to 300hp stock (declared by Nissan to be 280 DIN hp = 278 SAE hp, due to japanese gentlemens agreement to not exceed 280 DIN hp).
Lost a couple of hp to emissons and economy every year, finally dropped below the rated 278hp in the 96 model year after loss of VVT and gain of OBD2.
A well known internet personality says, the addition of a JWT chip alone, brings the hp to 317 and the torque to 337 lb-ft as these engines were detuned quite a bit at the factory, which makes this gain possible, usually chips dont keep their hp promises, this one is said to be an exception.
It also extends the redline to 7200 which brings the Q deep into the mid/late 90's mph in second gear.
This is a very safe mod with this engine as they were so well made originally (blueprinted all of them as a matter of fact, by domestic standards)
Also the VVT hepls make full use of the extended redline.
(I also have the JWT chip)
My compliments to the guy who raced the Q.
You must be a pretty good shifter and your car running strong for it to have been that close.
At hi way speeds, even a stock early 90's Q (assuming its been properly maintained, which is often not the case nowadays) can walk away quite easily from any 4 door short of a late model $55,000 plus BMW or MB (and still beats many of those).
The sodium filled exhaust valves make it possible for the ECU to run the engine hard even at speed and not have to worry about burning up the valves too much.
Nobody else except Nissan/Infiniti has had sodium filled exhaust valves in sports sedans ever.
Just figured I'd educate you guys a bit, as I had always assumed that Maxima drivers knew what a Q is, since we both drive large hi-end Nissans.
Having said all that, I have always liked Maximas and congratulate you gentlemen on your fine cars.

Palmer. Nice reply. Educational. I believe BMW used sodium filled exhaust valves(not 100% sure though) on their M series engines. The FJ20 Turbos used Inconel exhaust valves but I don't know how they compare to soduum filled valves

Sorry I havent been on to this board much lately. My Max is not boosted yet...hopefully soon courtesy of the Stillen Vortech kit. But my other car is a Porsche 944 so there is a boosted car in the family
After that race with the Q45 I'm in the market for one. They're pretty cheap and it'd be cool to have a blown Q45. Palmerwind do they make blower or turbo kits for the Q45? I want to buy a black on black '94 and turn it into an Impala SS, Marauder, Lexus GS killer!

Well on my 99 SE auto I had a stillen intake and y pipe with a greddy exhaust. we have a 91 q45. I had purchased a jim wolf intake for that cause you know when your 16 and when you drive moms or dads car you gotta do sumtin to it so dont flame about me putting an intake in there ok. But anyways when I would race my brother in the Q I would be ahead of that car untill about 60-65mph and then it would just walk me. Also those things are pretty quick on the freeway. If you punch it and when it drops the gears you will be up there fast.

My car is modded with OSCAI, Cattman Y-pipe and a Stillen exhaust. His car was not stock either, if it were stock he probably wouldnt have a chance against me. All he had was a Jim Wolfe chip and exhaust. IMO cone filters do nothing but hurt the performance of the car because they suck up hot underhood air instead of cool air like a CAI. Racing this car is a lot like racing a BMW 540i.
