I was checking out Sean Morris' blog and I ran across some 411 on the new G37 coupe. It's bigger, badder, stronger, and faster. The new VQ37VHR engine is definitely a nice piece of work. I rather like the VQ35DE even in it's basic 287hp form (plus some mods and tuning of course), but the 37VHR rocks the shit out of the 35DE without any work.
Bone stock I think this car will give the BMW 335i twin turbo a run for its money. BMW fucked up by putting a pair of puny bitch turbos on the engine. Sure a turbo car get much faster with a few mods, but there is NOBODY who makes a reliable ECU for the BMW yet. Flash/rom tuning isn't available yet. There are some bullshit piggybacks out there at the moment, but that's all they are: bullshit. 350whp this week, 320whp the next, and 300whp and a blown engine the next. Piggybacks and modern day OBD2 ECUs with a broad range of feedback just do not work. Don't believe the hype.
Features like a bedplate style main girdle that up until now has only been found on race engines and a few production blocks and variable cam in addition to infinitely variable valve lift is what will set this engine apart from other production engines right now. Honda VTEC is now officially old school with Nissan's technology on the market. Is it reliable? Can it rev to 9,000rpm? Will it last at 750hp? I guess we should be finding out soon. Especially with the long awaited Nissan GT-R coming very soon. The sooner the better because I put some cash down at the Nissan dealership to be on the waiting list. Anyhow, with every new technology means that there will be a new technology for us tuners to learn. No doubt Nissan has released a new computer which means that we have to wait again for a platform to tune with. I say screw it all: we'll just have to put Motecs and Pectel ECUs in all the new cars. The infinitely variable valve lift and cam timing means that the ECU will have to be fairly complex and fast. Closed loop control of four camshaft angles, 24 hydraulicly (not a real word) actuated valve lifters, and a complex crank/cam trigger system to along with that keep even the most high end aftermarket ECUs fairly busy. I can't wait. It should be fun.
