WHAT CAN I DO TO MAKE MY 06 INFINITI M35 MORE POWERFULL?

[INFINITIM35OWNER06]

I LOVE MY 06 INFINITI M35 I REGRET NOT GETTING THE M45 BUT WAS INTIMIDATED BY GAS PRICES BACK THEN. IS THERE ANY WAY TO MAKE MY M35 FASTER AND STRONGER (HORSEPOWER)?

i've asked the same question kinda and noone has answered me yet.

I got a 06 M35 sport1)AEM Cold Air Intake (robed fom my 350z)2)Greddy SP2 Exhaust3)soon as i get home ill be putting on some test pipes resonated probably going to fab some up. (if the ones from my 350z dont match up)4) im about to pick up a new upper plenum if i dont use my spacer. (spacer from my 350z)5) last is going to be tuning it with the parts. (going to uprev)

those will probably be your basic mods unless you want to go forced induction with a supercharger or turbo kit but your going to have to fab up some parts probably cause you will be purchasing a kit from a 350z or G35. parts to fab up will probably be like the down pipes to connect to your exhaust for turbo aplicaion. the supercharger kit souldnt have to fab up anything but donthold me to it im still trying to find a 350z or g35 with a vortec suprcharger so i can see the placement of the pipes and stuff under the hood but should be able to make it work on the M35 cause of the more room in the ngine bay.

Hardest thing for the M35's is really going to come down to tuning it i think since i havnt seen kits specifically for the M's i dont think theres alot of plug and play EMS's. on 7-8 PSI should be able to be tuned decently from uprev once i get them my car and they crack into my ECU.

ill be heading back home from iraq come thursday and ill be looking into alot of thos things. once i finish building my 350z (still waiting on my twin turbo kit to come in) im gonna hop into the M35. going to do the HKS Rotrex super charger. its gong t be a 350 z one and i going to make it work on the my M35. and also im going to pick up a set of long tube headers from a 350z and see how far off it is and add some pipe to make it fit on the M. my plan for most of this wont happen untill like july-october time frame.

Just remember or motor is one of the VQ35DE variants or a VQ35HR depending on the year. so most of the parts for the motor it self you can pick up from a 350z or G35. the hardest problem i been having is fiding out which VQ35 i have if it's a Non-Rev up or a Rev-up motor so that i can purchase parts accordingly. On our VQ35 motor's if planning on forced indction i wouldnt suggest no more than 8PSI on stock bottom end or try not to push it more than 400-420whp cause the connecting rods is what fails.

Just keep in touch with me on my email [email protected], hope i answered your question. and i hope more ppl join in this time since i had no replies when i asked the question.

Your best bet would be to trade it in on an M45.

Or you can put a nice twin turbo kit... vinnytenracing.com, for example. Here is a link to a car done by them: http://www.cardomain.com/ride/3001943

Actually, be glad you purchased the M35 over the M45. Like Z33PWR was saying, at least you have options of parts from the G35 or 350Z. There isn't anything out there for the M45. Your only lacking 22 hp and 68 ft lbs of torque over the M45. Well...the HP difference isn't much, but the torque difference is pretty significant. Either way, you have the parts out there to turbo charge your M35. That would be the better more efficient way than supercharging it. You would get bigger torque numbers and increased fuel economy (Note: Have to keep foot out it to accomplish that!). In the end, you would have a rare fast sweet ride!I wish (I'm not alone) someone would produce a kit for our M45's, but most manufacturers are stating it's not going to happen anytime soon at the moment.All we can do is place an exhaust system (Which is a good upgrade) and a different direct replacement filter in our cars. There are no custom tuners that I know of locally thus far that will mess with it due to lack of experience with one. Someone has to start somewhere.....but who wants to place their ride as that ginnie pig? Not me.I think you made the wiser choice over the M45! If I could do it again, I would have chosen the M35 and then added on the power mods!Good Luck in your quest!

For you M45 owners out there there is something out there for you guys some might like others might not. take a look into the STS rear mount turbo kits if you want some boost it's easy to piece one together if you had goten one from the Z or G but id take a look at one of them cars and look at the layout to see what woud have to be fabbed to get it all buttoned up. ive seen a few domestic cars use STS and at 8 psi produce some nice numbers. its something good to look into but i dont know much on the VK45DE (sorry if i go the engine code wrong) but the same as the M35 would probably will have problem finding a EMS. I have used UPREV in austin Texas with my 350z and they do alot of work on stock ECU's for reflashing Z's, G's,Titan's. they havnt done any M's cause ive called them and talked with them to do my M. but once they have cracked the ECU they could do Reflashes. ima take my M to them while im at home on vacation. and see how long it will take them to crack the ECU. ill post up once i get all the info on the uprev reflash once i get mine done and if anyoe is interested could contact them. can check ot their site http://www.uprev.com

The STS would seem the better way to go, but you would have to deal with an extra 3" or 3-1/2" piece of piping to go back up towards the engine. I'm not so sure that would work, but then again, I haven't really been under it too much to determine if there is a clean route for the piping. Then there would be the tuning issues.... Does anyone know of a custom tuner that has successfully tuned a M35 or M45?

M4T5,

Your power output comparison between the M35 and M45 is incorrect.

The HP difference for a 2006 model year is 55hp, and 70ft/lb of torque. Not an insignificant delta. Especially the torque figures.

But in my case, coming from a 12 sec even Subaru to the M45, I find the stock power sufficient - considering the weight of the car, its fuel economy, and luxurious nature.

All true statements. Particularly for the earlier model years like the 2003 and 2004. Simply not enough cars sold for the after-market to be interested in doing the research to make anything happen.

Oh, well. That is why I simply will try to keep my car in excellent running condition as much as possible. Most of the time, the stock HP and torque specs are way good enough anyway!

Sorry, I was resourcing recent power figure comparisons. I wasn't thinking about the 06 M35's power plant putting down less power.I do find the M45's power exhilarating in bone stock form. I guess I'm power hungry is all. I hate all the dead ends I keep turning up on custom import tuners that can't tune the car.I just hope the future holds a place for our cars in the aftermarket industry. There are just a few sparking up here and there. Though, they are exhaust systems mainly. It's better than nothing though. It's a start. Hopefully it doesn't all end there.I think all it would take would be one reputable tuner to unlock the M's computer secrets to really kick off these cars in the aftermarket industry. We are all different drivers. Some like this car in stock form, while others want more. There's nothing wrong with neither one of those owner types.

I'm starting to see more and more M35's and M45's on the road lately than ever. I think there are at least four 06' & up M35/ M45 owners in my neighborhood alone. I do see more G35 sedans and coupes more than anything though.Not sure if it is significant, but just an observance here in the Houston and surrounding area.Do you see sale figures to increase, decrease, or stay the same this 09' year?

Yep. Get a bigger jockstrap and trade it in for a M45.

Hello everyone, new to the site. I just purchased an 06 M35 and love it. I've been reading this forum for a while and it's great. Just had to get the intro out of the way.

Before the M, I had an 05 G that had a dual stage N20 system on it. After a lot of research, I found this to be the least intrusive way to get power. The old myth about N20 being very dangerous is over in my mind. They've come so far in designing so many different systems, that a good system, properly installed, is a very safe method to get power. Just an option.

I came from 6mt.net and am happy to find just as helpful forum for my M.

Another option is to spend the $8000 grand that you would spend on a TT kit and go buy a nice used Hyabusa.

Now...if only they would add A/C and windshield wipers to the Hyabusa....then I would buy one over that TT kit!

I wouldn't trade mine for the world. Drive the car when it's not ideal riding weather, the best of both worlds.

on the M35's im seeing from my personal expierience that a simple super charger with soe longtube headers would be the nice set up for the main reason you cant go wrong with getting boost happy and blowing the motor. then comes the biggest question how robust will our trannies be with the extra power. i think with 400whp is more than enough in our cars and speciall with the lighter M35's wih the V6. i really wish they offered the car with a Manuel not just auto.

so far im doing my 350z's full build and im like 20k into it toal cost is going to be near the 30k and i wouldnt want to go through with getting another whole motor built lol. now i did see something that peeked my interest for the M35's if you was to go N/A with those ITB and a decent cam, longtube headers and a tune you should be able to get into the 300whp range i think. i dunno what the power difference is from the M's but my 03 350z put down like 220 whp 207 torque with all my bolt ons and i was at 247 whp 238 torque after i got all of it tuned this was all at uprev in austin. im guessing that our M's are putting to the wheels some where around 230-240 whp with bolt ons and ITB's should be close to the 300 maybe. but im a boost junkie

im looking at the Kenstyle kit for it too. that kit is sexah. im still talking with the wife tho so until i have her convinced on all the parts i want to do to her car its still 50/50 she likes my taste so hopefully after she drives my car she will be sold on the supercharger

[Z33PWR]

i was browsing one of the other topics. for the people who have been reading this topic please understand this when it comes to adding bolt ons to our cars. a CAI, Exhaust, Headers all your simple bolt ons will not produce that much more power our ECU's are very restrictive and have set points it trys to keep on the AFR with out ECU reflash you will not get all the peformance from the bolt ons. some of the bolt ons will rob HP without a Tune. some of the HP gains without a tune on our cars will mainly come from changing out catalytic converters to Hi flow ones or test pipes which will void warranty more than likely. with an exhaust you will get a nice sound out the back end and maybe pick up 3-5 hp or maybe even lose a couple cause the ECU is constantly trying to stay at a certain AFR, Before some go out and buy alot of parts trying to gain HP and go faster.

I hope to have some of the parts on my M35 and hope to get a reflash so that my parts will take effect. with out the tune you will gain minimal HP. im in Kuwait as we speak omw home and thats one of the first things im doing is talking to a Tuner to get the ECU reflashed. If im successful on the Reflash M35 owners should be good to get a reflash but someone with a M45 would probably have to send in a ECU or if they live i texas bring their car to the shop so they can crack the code on the M45. but small steps at a time and alot of custom work will have to be done to our cars for more performance. im sure there is good potential in the M badge.
