Might wanna try Richey Collision.

The donuts have been dropped..I repeat, the donuts have been dropped (not on the floor, as in dropped off for the slow people)

Sorry couldnt stick around..fiance is sick AND on her period....its been the best week ever!:shakes head:, leave for work in a hour and it was balls cold with rain. Good enough potion to drop the package and jet lol

Will check it out! Thanks!

Anyone know a reputable place that can build a performance motor here in Houston? I think I would like to build a NA motor that puts down about 450whp. Is this feasible and still be streetable?

Thanks

I wouldn't want to go down that road with the VQ. There's a couple of extensive threads here about that, but let's just say *if* it's even possible to reach 400+ whp on an NA 3.7, it would require a ton of time and money (basically replace virtually everything in the engine with aftermarket stuff, brand new heads from another engine, different exhaust cams, probably ditch VVEL and thus switch ECUs as well, etc... and then develop a few new parts). You're going against the nature of the engine going that route, and it'll fight you every step of the way. It's a losing battle.

It would be far cheaper (and much more turnkey) to do an SC or TT build targeting 450rwhp (rather than trying to shoot for 5-600, which is probably what ends up destroying some of them).

Or if you're really stuck on NA and you're willing to toss the ECU and stock dash (which again, a crazy VQ37 build would probably end up requiring anyways due to head changes), you'd get more power for far less money by doing an LSx conversion. It's been done before on the 350's, but I haven't seen a completed 370 yet. If (really, when) my engine dies from track use, I'm likely to explore that route myself, but we'll see when the time comes. If you're set on Nissan loyalty, a similar option would be to throw in the VK56DE.

Thanks for the quick and informative reply. I currently have 2 SC Mopars and was thinking it might be nice to build an NA but had suspicions that it might be expensive. Not knowing the Nissan perfromance capabilities of the 2009 370Z, I thought I would ask the question and appreciate your feedback. Looks like I might end up with a 3rd SC car!! LOL

I have done a lot of reading on the FI section but had not seen much on the NA builds other than bold-ons and tunes which would not yield the end point I desired. Again, thanks for the reply.

Yeah it all depends on what you want to do with the car. Bang for the buck and reliability/ease, I'd say If you're after max peak HP and maybe some drag racing do the GTM TT kit. How much power is really down to how much wallet, and 600 should be possible without going way too far. If you're doing a road-race car where you expect to sustain high RPMs for long periods, maybe do the GTM SC kit and tune it conservatively (larger pulley, etc) to keep it reliable at ~400-450rwhp.

Chris Forseberg is running a Titan V8 engine in his 370 and making that much power. Might want to look into that.

Thought his was a Nismo racing engine (not based off of any production v8) from a Baja truck or something? Pretty sure that's what I had read. It's pretty boss, either way.

as of sept, still nissan racing titan engine.

Under the hood, Nissan's VQ37 motor has been ditched in favor of the torque from a V8. Forsberg and his team have decided to stick with the VK56-based Nissan Motorsports 5.6L V8 racing motor that's powered his cars for the past several years. This year's motor, however, runs individual throttle bodies protected by an AEM carbon fiber air box and custom MA Motorsports 4-2-1 long tube headers that expel the fumes to a custom dual 3.5-inch exhaust. An electric water pump and Mishimoto race-spec dual radiator keep things cool while Electromotive ECU and coils take care of the spark

Ah, guess it is VK based.

Calling it a Titan engine is kinda silly tho :P

So how much are these so called race engines??

Info from the Wik:
The VK56DE is a 5.6 L (5552 cc) version built in Decherd, TN. Bore is 98 mm (3.9 in) and stroke is 92 mm (3.6 in). Output is 317 hp - 320 hp (227 kW) at 4900 rpm with 385 to 393 lb·ft (522-533 Nm) of torque at 3600 rpm. It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS) on the intake valves. It also has 4 valves per cylinder with micro-finished camshafts and ductile iron cylinder liners for increased durability.
Motorsport
Nismo also uses the VK56DE for FIA GT1 racing. In race trim, it produces 600 horsepower and 479 pound-feet of torque.[5]
The Nissan Motorsport VK56DE was launched in Australia for the V8 Supercars Championship in 2013 by Kelly Racing in Melbourne. The engine has been reduced in capacity to 4,990cc to fit the V8 Supercars regulations. It has a bore and stroke of 102.69mm x 75.31mm. It will be fitted to a Nissan Altima version of the V8 Supercars "Car of the Future" specification that will compete from 2013 onwards.[6]
Applications:
2004–present Nissan Armada, 317 hp (236 kW) and 385 lb·ft (522 N·m)
2004–present Nissan Titan, 317 hp (236 kW) and 385 lb·ft (522 N·m)
2004–2010 Infiniti QX56, 320 hp (240 kW) and 393 lb·ft (533 N·m)

Notes:
The Titan, Armada, and Pathfinder power figures are for regular 87 octane fuel. The 320 hp (240 kW) Infiniti QX56 is tuned more for premium (91+ octane) fuel.
Some VK56DE powered vehicles are E85 capable.

The thing is a race engine.

It isn't a Titan motor.

It has individual throttlebodies in a huge intake plenum, race heads and cams.

It's nearly 600hp all motor, not a Titan motor.

That's the only point I was trying to make.

Later.

I understand that its modified, not trying to be a **** just was posting some more info on it. Sorry I called it a Titan motor, no need to get butt hurt.

Man, I really don't know what intake to get with Houston weather. All the rain is killin it for me
