2009 G37x - How limited am I when it comes to mods?

[pits200]

I am getting rid of my travel car which is a 2001 Acura CL-S and my home car which is a 2008 Acura TL and moving over to the Infiniti family (G37x) because of my detest for the cosmetic design of the new TLs.

I enjoy modifying cars and will have some money to play with since I have both of the cars listed above paid off. I keep searching these forums to see what people have done with the X but can't find anything of substance. I will want to spend around $7,000 in upgrades and was leaning towards a 335xi but with all the problems I am not spending the extra money on that vehicle.

1.) I would like to lower the vehicle (I know the argument, why buy awd then lower the car, but I only want to lower it by an inch which won't deter me much when it comes to snow driving.)

2.) I would like to add a conservative turbo (50-80whp addition, I'm not trying to milk every hp out of the engine) since I want an auto transmission and don't want to have to change many internal components of the engine.

3.) I'd like to change the sway bars to obviously a stiffer than stock bar.

Those are just the 3 mods that I can't find clarification on whenever I check for parts on the G its either for the RWD sedan or the coupe..

Could you guys help me out and tell me if the things I listed above will be feasible if I purchase the X or if the parts don't exist and probably never will since their isn't a large market for them.

Thanks so much, your input is appreciated.

You'll love the G!! I hate the new Acura's too...really ugly front and rear.

A conservative turbo system will be around 4-6k...add exhaust and suspension and you'll be over your 7k mark.

The car is new so it will take some time for the aftermarket to catch up. I know Stillen is developing a supercharger for the VQ37.

Here is more info: http://blog.stillen.com/2010/0...ailed/

Thanks for the response, I know what you mean about the aftermarket parts catching up, but I noticed even for the previous generation with the g35x, not many aftermarket parts were ever even produced for it. (i.e, suspension parts)

I am just concerned that aftermarket parts won't be produced for the X and I'll be S.O.L and have to part things together to make my upgrades work.

I read up about the Stillen supercharger and that was great info but the wear and tear on an engine from a supercharger scares me.

As for the budget, you know how it is with cars, whatever amount someone says they will spend you can bet they will end up spending 30% more than what they planned.

You'll have more aftermarket parts for the RWD version than for the AWD. That's the nature of the business. More people looking for aftermarket parts with RWD version of the G.

However don't let that steer away from the X.

There are planty enough for the 07 and 08 X so it will come for the 09+.

Also some supplier have not tested their product on the X so simple just state it it is only for the RWD version. If you look aroud you'll find people tried them on X and they fit just fine.

For lowering you can get the Eibach prokit and that would give you just a little over 1" drop.

Here is one of the site you can look around.

BTW the engine internals are good for well over 500 hp. GTM got 583 whp and 523wtq. THey have a kt for 37 and it is $ 7500. Little over what you budgeted yourself. However well over the hp what you wished for. Stage1 is up to 500hp.

Thanks for the info zozo, ya that turbo is much more than I was looking for, perhaps I will wait for the Stillen SC and see what that is going to run. Since I wouldn't have the time to do the turbo install myself, if a more economical turbo came out, does anyone have a guesstimate as to what the install might cost?

So now I know the internals are able to withstand a good amount of hp, but do you think the 7 speed auto transmission could handle that kind of hp especially being AWD and the added stress.

This is fun thinking about what to get but it's also frustrating because I would hate to do the job wrong and run into problems down the road because of my own stupidity.

[zozoka1212]

I'm not an expert with this. But It sure seems like Nissan building the main parts verry durable. I don't see the transmission as a week point. Especially with the power you are looking for. There are G37 with 7 speed auto and have the TT set up.

AWD system is simple amazing. I've not seen a single ATTESSA AWD fail in any G system. But again this was in the older skylines too so nothing new for Nissan.

If I were you I would contact to GTM and ask few questions before pulling the trigger. I would ask if they installed TT in any X model. I am sure they did. It would be nice to see how well it holds up.

I think what you should look into is the remote turbo system like STS or as Joe suggested the supercharger. Supercharger is the easier to install. You can do it in the garage.

Which one is better? I am sure you know there would a huge debate. Some prefer the SC some like the T system. I don't think people can even agree on the single vs tt set up.

[joe603]

All things being equal, a turbo is better...but you'll pay more for it as it's more involved. The exception is the STS systems...but I'm not a fan of having a turbo as a muffler for many reasons.

FI is great, but it will accelerate engine damage.

if your going for a 1" drop your best bet is eibach for the X.

the AWD part of the car really only applies to fitting parts around the AWD system on the G... so if you see RWD and its not a part that has to fit around the AWD system like an exhust and certian suspension parts in the front of the car... there is a good bet it will fit and work just fine on the x model... i mean the engines are the same between the rwd and the awd...

but the g37x is new... so wont be a whole lot out yet...

Well I would assume that many of the parts are interchangeable being that many of the components of the X and RWD are the same. But I found this not to be the case. For example, the rotors and brakes are different on my wifes 04X. I think the springs and shocks are slightly different too as to accommodate the extra weight of the X. You figure more parts would come out for the X being that the coupe also comes in AWD form now.

Oh well, I'll just have to wait and see. Joe, you mentioned the extra wear and tear on the engine going FI, what about mid horsepower cars like a mini that is FI, are those people expected their engines not to make it much past 100k miles?? I just am curious if you could enlighten me as to what parts would fail faster with FI. I know with more power comes more heat but what side effects are common with a turboed/SC car?

Thanks again
