I've been asked to start a thread about this, so here goes

I'm finally picking up my 2009 G37 Sedan 6MT on Wednesday with the GTM Stage II Twin Turbo kit. The work is being done by Sharif at Forged Performance. A buddy of mine ("DmfG37sTT" on here) and Sharif have both eluded to my car in posts here and there, but I have kept quiet about it because I knew there would be issues being the first G37 Sedan with Twins. I dropped the car off 7 months ago and although most of the work was done quickly, there were signifcant delays with the programming of the ECU. Sam at GTM had to wait on Uprev to get their programmer working for the new 4th generation ECUs found in the 09 G37 and the 370Z. The 08 G37 Coupe still has the 3rd gen ECU which programming was readily available for. Even after Uprev had their software working initially about 2 months ago, there were still issues where certain ECUs would lock up or not work properly so that required even more investigation from Uprev. Then, after all of that, Sam had to actually do the tune on the 370Z he had in his shop and then send it to Sharif.

Here is what I'm having done:

GTM Stage II Twin Turbo
3" Downpipes and External Waste Gates
HKS EVC Boost Controller
HKS AFK Knock Amp with dual A/F sensors
HKS Camp 2
KW Variant 3 Coilovers
Rear Camber Kit
Hotchkis Front & Rear Swaybars
OS Geiken Twin Plate Clutch & Flywheel
Volk RE30 Limited Edition Formula Silver Wheels
Toyo T1R 255/35/19 & Toyo T1R 285/30/19 Tires

No one made a 3" exhaust for the Sedan until now. Sam at GTM has custom made one for my car and will be delivered at my home on Wednesday. It will kill me to sit around the house Thursday (damn Turkey Day) instead of driving my car around and putting on the new exhaust, but I will put the new exhaust on the car Friday morning and head to a local dyno so I can post some numbers.

 

Congratz on your build and I cant wait till we can tear up Saint Charles

This is an amazing build, congrats. I do have one question. When you bought this car was it your intention to do this all along? For example you wanted to spend the money modding the car and making it a killer as opposed to paying more upfront and driving a stock M3 etc...

 

I'd imagine that this setup has a higher "up front" cost, as you don't make payments on the mods unless you card it (which IMO, is rather unwise)...

 

What do you mean mike?

 

Well, you can spend 65k on a well equipped M3, or 40k on a well equipped G sedan. The cost of the car is more on the M3. However, assuming you have great credit, actual out-of-pocket cost will be nothing, as you can finance the whole car. The monthly payments would of course be higher on the M3.

However, you can't add the cost of the modifications on the G37 into the financing of the car (well, you can, but if you put nothing down, then you have no equity to finance against, so you effectively can't). Therefore, the cost of the modifications is paid out of pocket (cash, credit, whatever). You could finance the mods, but that would be pretty expensive. Even unsecured loans come with a best rate of 9% or so, and getting a 5 figure unsecured loan isn't exactly easy.

 

ok got ya

 

@OP: Congrats on being the first!

 

Good stuff OP

Interested to see what kinda numbers you put down with the 3" exhaust. (You'd be the first sedan with a TT and a 3" AFAIK)

 

No, I didn't know I would go this far...in fact, I only had the car 2 or 3 weeks and I put on a Stillen Gen 3 Intake and the FI Cats and Exhaust. Then within a few weeks of doing that, I decided to take the plunge...luckily I have sold the Intake and the Cats, now I just need to sell the exhaust.

Given all of that, I really like the G37, and it will have a lot more power than an M3.
