Anyone have it? Also is it worth buying for my g37x awd coupe 7speed auto. And without a tune? Or will this require a tune. Also, what headers do you recommend with my g37x awd with my ark grip cat back

 

Welcome to the forum, please utilize the search function of the forum. Many of the questions you have have been answered already and you can find a much more detailed answer in the other dedicated threads.

I have the m370 manifold. First off, bolt ons are going to have minimal horsepower boosts. The real power maker is forced induction. I have almost every bolt on, and know what I'm talking about. You don't *need* a tune, but it definitely helps maximize your performance. The g37 already comes with engineered headers, so swapping them is not really necessary.

Welcome to the forum, enjoy your G36x AWD, lol...

 

Why do you say enjoy my awd? And lol?

 

Also you never answered if the m370 is worth the money or not. Also, do they sell plenum spacers for the g37 yet

 

"Worth the money" is very subjective. It might be to me but not to the next guy. What's your criteria for it being worth the money? What are your expectations from it? As was mentioned in the first reply to your question, if you were to actually take advantage of the forum and search the forum and read the posted experiences and impressions of people who have it, you might be able to tell if you'll feel it's worth it for you.
As to whether you need a tune with it, it's not required but that's definitely how to get the most benefit form it. It's best to get all the bolt ons you want to have before getting a tune so yo don't have to go back and pay again for a retune.

There is no plenum spacer for this engine, the modified intake manifold serves that purpose. There are headers made for this platform that give some gains over OEM, but their relatively small gains and price and installation cost if you are not doing DIY make them a poor value to most people.

 

The plenum spacer for the G35 fixed a design problem that caused the front cylinders to become starved; the g37 doesn't have that problem, so no spacer necessary.

I was just chuckling because you kept saying "g37x AWD" when a g37x is always AWD, it seemed redundant. There's nothing wrong with the G37x.

It was worth the money for me, but as BB mentioned, I have all the breather mods and I have a tune.

 

Only reason i keep saying g37x and throwing the awd part in there is because some people bypass the x part and still give me listed items and tell me to buy parts that are not compatible with awd. So i kind of throw it in there for people who dont pay attention

 

The aftermarket parts that I can think of that will be different for an X model would be suspension, drivetrain, or exhaust. I believe (I could be wrong) that most any engine related part or modification would work for all G's regardless of coupe, sedan, convertible AWD or RWD.

 

That's correct as far as I know. All three body types share the same VQ motor.

The X should have a square setup for the wheels. If you want the AWD system to be happy, you should keep aftermarket wheels the same at all four corners.

 

Thank u buddy! Im hoping by the summer to have around 320whp!

 

That's ambitious, good luck!

 

So you will be installing the supercharger then...right?

 

Who are you asking?

 

I'm not sure how much power these cars make to the wheels but im going to assume its somewhere around 280, if you want to make 320 by summer then you have to come up with 40hp, and boltons cant get you that...you might an extra 20 in boltons but thats about it.


**when i say 40hp, and 20hp i mean to the wheels not to the crank. Theres a big difference all thanks to drivetrain loss.

 

Installed mine today.. there is noticeably greater pull in the mid range of the powerband... It was worth the money to me
