Topgunz full supercharger kits!!

takemorepills · 08-27-2019, 12:20 AM

OK Guys, I have spent a bunch of time going back and forth on this forum, Youtube and the G37 forums and I think I have it figured out.
For a 7At G37 looking for around 430-450whp (or more) 91oct, can someone(s) let me know if I've figured it out correctly and what I may be missing?:
1. Buy TopGunz A2A full kit
2. Buy Aeromotive 340 fuel pump and CJM billet tophat assembly
3. Buy injectors somewhere around 750
4. Keep an eye on my stock cats and probably get some (Berks?) in the near future
5. Get ECUTek, I have a reputable ECUTek shop near me.
6. MAFs, shouldn't need to upgrade if I'm under 500hp?

That seems like everything I could find, am I on the right track?

You can use stock MAFs and get an Omni or Haltech MAP to ask your tuner doing hybrid tuning in ECUTek. Don't use stock cats. It will only hinder the performance. Remember the more the back pressure you reduce the more the performance you can improve. I'd recommend injector size 850 If your sure you won't go E. Last but not least, I'd strongly recommend you get a trans oil cooler for your automatic G.

Thanks for the suggestions, I'll definitely go with 850 and a trans cooler.

If you need help with anything (if you're doing it yourself), I'm right on the other side of the water from you!

I went with a fuel return system and test pipes as well. I got ID1050x injectors. Topgunz can get you a great deal on those! My car runs like stock even with injectors that big. I also still use stock MAFs.
