Share links for more horsepower!!!

[sbauer]

Whats going on everyone? Im new in here so give me a little help!!! This is my first Infiniti, a 2006 M45 (2wd). I am looking for some engine upgrades. I've put some new 22's on it but I've decided to go with 20" this spring so I can put the AOS air bags on it (also in spring) but i want some more HP till then.
Looking for items like...
lightweight pulleys
throttle body
cam/valves ect

Can anyone help???

[mexillis]

AOS? There aren't any light weght pulley's for the M45 but there was a brief thread about it were a co. Was gona make one. Only Impul makes a throttle body which is a Japanese based company and is very expensive. Same for cams. Best horsepower increase will be exhaust then get it tuned with UpRev, hopefully there's an authorized tuner near you. Lastly the best dyno proven Air Intake is a few threads down.

[sbauer]

AOS is air over shock. Bolt on system from x2industries.com make a good set up

Def first look into exhaust.... eliminate cats (largest choke point,) go as free back from there on as you are willing to stand noise wise. Cams are a good choice, and sound good to boot. I've always like JWT for their cams, especially if you want to maintain oem ratio. Screw the throttle body... I'd go with a stroker kit, if ya really want to do some NA power, or move to FA if ya feel froggy.

But for just tinkering, intake, exhaust, maybe cams, and a tune... def a tune...

Also u have the 45... quite ur bitchin bout HP!!!!! :P

[sbauer]

I think I have to keep the Cats, only becasue of Marylands anual emmision test. unless you know a way to get around it? and as for HP, im going to steal a line from my fiance Laura "Its never enough!" although she may not have been refuring to HP. lol.

My car club consist of Audi A8, CLS500 benz, 645 beemer, G8 GT and a few others. I need to be faster lol. its my addiction

[sbauer]

:-/ JWT was a bust, couldnt even recomend me n e where. looks like i am stuck to tuning, intake and exhaust. Def keep an eye out for me though!! going to sink motor money into weight reduction i suppose, carbon fiber trunks and hoods are easy enough to come by

[fat3oy]

http://www.jimwolftechnology.com/custom ... PartID=473 for the cams... have a shop install them, have tune ready...

can use High flow cats if you can find them... they will keep you emission legal... and screw weight reduction, not a lot to take off without still being heavy, go stroker or fi

[sbauer]

where con i find the stroker kit?!

[fat3oy]

where con i find the stroker kit?!

lol, thats up to you... a stroker kit is a new crankshaft rods and pistons typically... i'd also run more fuel depending on compression... but off top of my head Impul makes good parts and should get you started, other than that cosworth is top of the line...

[mexillis]

Those cams are for the 5.6L not our 4.5L. Where in MD are you OP? Send me an email at mexillis1@gmail I have some info about custom exhaust in MD. That Impul kit is 20 grand by the way and req you to give up your motor as in a core exchange. If you have money to blow on cf hood n trunk id say invest in N2O instead and a tune. For a MD Tuner look up Hills Garage and see if you can talk to Frank, he's booked all the time so you'd want to make an appt asap. Also you can throw in the VLSD FROM A g37s if you can find one from a slavge yard or you can buy new. You just need the the halfshafts,pupkin, gears and its a direct bolt on. That'll raise ur gears from 3.39 to 3.69 and the added benifit of LSD vs open diff.

[sbauer]

just hit you on e-mail. its easier to get me on there, i got some Q's about that rear

[Tony Two-Tone]

Whoa, whoa. What's all this talk of stroker engines and whatnot?

OP, the VK is going to benefit most from breather mods and a tune before digging into the engine.

There is a company working on the lightweight pulleys for FX45s that will work on our engines.
The cams for the VK56 will fit the VK45
A built engine from Impul will run you $20K.
Port the throttle body
Custom exhaust
FI is going to be $$ no matter which route you try to go
UpRev for tune
VK56 headers (shorties) will also fit with just a few modifications to the flange
Rear end change

And unless those other cars in your club are heavily modded, you should be as fast, if not faster, than they are.

[fat3oy]

Meh, everyone scared or cheap to stroke???? do it yourself save money...

And the JWT link was just an example, I figured op would kno how to search from their, but Mex to the rescue again...

Tony, does the VK really benefit from shortie headers? Always practiced long tube on bigger engines with a larger running diameter as well, just curious for I kno shiz about these engines...

Oh and OP, Mex was dead on about a VLSD or LSD as opposed to open, power to wheels and overall vehicle performance/handling is a biggy with that open diff.

----------------

Since everyone is talking so much about breather mods, I would assume that the VK is as air sensitive as VQ's, and air can really benefit if done right under tune, so I'd look at cams as well, a cheap mod relativity. Other than that, exhaust/intake system isnt going to yield crazy numbers for him to compare to his peers...

I'm curious also as to infatuation on the throttle body (spacers, port) not trying to bust balls in the least, just wondering...

[sbauer]

porting the throttle body is just a quick easy way to increase flow, and decrease air friction. I saw a big gain from intake and and throttle body on my old LS1 motor from a different car. Just hoping for the same effect.

[mexillis]

Is there any proof that the VK56 cams will fit the VK45 engine? There's a thread from Ken in Az that made some JBA Titan headers fit the M45 as Tony said with some minor mods. It helped with low end torque I believe from what was shown on the dyno. Considering there isn't a stroker kit for the 45 wouldn't it be $$$up the a** for everything involved since it would have to be custom? There's a company that fabricated long tube headers and made a M45 rear mount TT set up but never showed gains or anything besides pics. All I have is ex and tune and that put me at 13.5 in the quarter mile. Considering the weight and type of car this is its not that bad. That's only a tenth off of the new M56 so I'm not too disappointed. If I had some better tires and more track time I could probly match it.

[bbs350z]

imho, your looking at some serious $$ to make some power out of your motor. lack of aftermarket support, and companies interested, and most importantly, the m crowd is a very small group of enthusiasts in comparison to other popular models. your best bet, bolt ons and live with it, or buy a factory fast car, not a 4200lb lay-z-boy with minimal aftermarket support

[Tony Two-Tone]

Yes, the VK does benefit from shortie headers.

Yes, the VK56 cams have been confirmed to fit. There aren't very many differences between the VK56 and 45.

A stroker build is not about being cheap, it's about being smart. For what it would cost to build a stroker you could swap in a built S/C VK56 or even a VQ35DET/T. My ideal swap would be the VK50 from the FX

Yes, the VK reacts in much the same way as a VQ in it's love for breather mods. The VK is almost literally a VQ with 2 extra cylinders. Nearly EVERYTHING is the same.

[Royal1262]

I love the 45 but I hate the "choke" feeling I get through some of the bands. The car is a monster around 3000 rpms. I feel the HP+Tq the most at 80-100. I have ex + intake and the other BS mods like TB bypass & oil bypass that made no difference in performance. Has anyone done the cam upgrade that can report on gains. I would love to get more out of this beast but I feel with the mods I have currently Ive been wasting my money.

[mexillis]

besides you saying it does can you show us some proof? Im not tryn to bust your chops just tryn to see some real data. I havent heard of anyone saying this until now so if it does fit that would be nice to know.

I would start with a tune since you've already done intake and exhaust.

No worries bro, I don't take offense. Logan over on Infiniti Scene confirmed that the VK56CS2 cams from JWT will fit (Link). As far as the actual install, no, nobody has tried it yet. It's definitely on my list, but I have a few things I want to do ahead of it.

intake and exhaust mods will only waste your money and maybe you will lose some torq, imo, these cars are designed very well and anything short of forced induction will be a waste of money. You can uprev tune it for around $600 but you'll only gain 10-15hp max at the wheels, and a stock 03 350Z will still smoke you at the 1/4 mile. you decide.

[Tony Two-Tone]

And where are you getting this information from? Stock for stock, the 1/4 mile times are almost identical for the '03 ( and any other Non-Rev Up) Z and ANY M45 which is shameful (to say the least) for the Z because it's a 2-door, 2-seater car versus a 4-door loaded luxury midsize. Do your research before you start typing next time. And don't bother replying, your credibility is now 0. Good day, sir.

Huh......please clarify....based on comparisons on several sites, the 03 350z is 3 tenths faster in the quarter mile than an 07 m45 (both rated stock)....but what you're saying is that a stock 03 350z will "smoke" a tuned m45...? Pssssh. I guess the guys that have the m45 and can afford to mod their cars should dump their luxury v8's for an 03 z in order to "smoke" people on the streets?.....umm, sorry buddy...I think the majority of the m45 owners are laughing at your @$$....... Including me and I have the m35....there is always that 'one guy' that starts saying " that car will do this, that car will do that....blah...blah..blah....." This thread was created for modding ideas and not immature gestures like what you clearly and ignorantly pointed out.....just my 2 cents.... Just please tap-out now while u can.....or just go to sleep

[Iconic]

6 speed Z will take down a m45 anyday on the track, stop bs, how many of you actually been to a track?
lolz at the guy asking for cams and what not, m45 is a cruiser with zero after market support, buy a m35 slap a stillen charger kit and call it a day.

thread =fail

[sbauer]

I enjoy my lazy boy on wheels, and have NO problem dropping a few thousand into it. And the point of the thread is a collective spot to find ideas on HP and upgrades. Don't be salty cause you dont have the wallet for it. Sit your @$$ down and click I different thread. Your insult.... Failed

DIdn't I tell you not to reply? What you have to say is incorrect and therefore has no place in this thread. You don't know what you're talking about. Do some searching before posting any more of your misinformed rhetoric anywhere else.

For everyone else, the VK56 CS2 cams from JWT have been installed in the FX45 and once his port/polish job is finished and the car tuned, numbers should be posted. Just based on what I've seen, they gains will be impressive.

[mexillis]

Iconic, just because your maxima can't keep up with a "6mt" z doesn't mean the M45 is slower. Obviously you don't know much about the cars you're comparing or you wouldn't post the stuff above. Its ok though, I suggest going through some of the threads from here and educate yourself. Quick question for you though have you taken your car to the track? If so let's see your time slip.

[EniGmA1987]

There have been a couple twin turbo setups done on the M45, they cost around $10k to get it done if you dont do some massive crazy setup. JWT can do that, IDK why they said they couldnt help you. Also there are places on the west coast near me and in San Diego that can do twin turbos and have done them before on the M45. If you want real added power this would be the way to go, but small bolt ons.

Having personally felt the differences between stock rear differential and the G37's VLSD rear diff with the 3.69 ratio I would haver to say this should really be done as well. They car feels like it gained 75 torque on the low end just from this. Of course it didnt, but it sure feels that way and the car really gets up and moves. The best way to describe it is the car feels much lighter on its feet.

[Tony Two-Tone]

I've yet to see a turbo setup on a VK45, but I bet it would be pretty impressive.

Long tube headers are also in the fab process right now for the FX. They should be adaptable to the M without too much trouble.

[mexillis]

Look up fluid motor union. They made the rear mount TT set up on a m45. Only thing is they never posted much about it.
