Heard and duly noted!

Only thing is... I am using the stock stillen fuel pump that was swapped out for the OEM fuel pump.
So I would need to get a 450 or 485, and then an S1-SE return kit BEFORE needing a twin pump then, correct?

Yes if you do the S1.SE + 450 pump that will take you really far before needing a twin pump. 700whp in turbo cars. Should be at least 600whp for supercharged cars.

Hey cupcakez - I sent you a PM. I have some brand new CJM goodies that I decided not to install and am looking to sell along with a new Walbro 485/450.

Gotcha.

So the order in the next few upgrades I plan to get should be like this?:

1st Upgrade: TopgunZ A2A Kit

2nd Upgrade: S1-SE + Walbro 450 Fuel Pump + Injector Dynamics 1300x

3rd Upgrade: 928 Motorsports Supervortech V3 SCi Impeller Upgrade

4th Upgrade: Triple Pulley Swap for increased spinning

5th Upgrade: Level 10 Bullet Proof 370z Transmission Package

6th Upgrade: F.I. 7 AT Billet Aluminium Flex Plate (Cause I have 7AT)

7th Upgrade: Tune from Sebz in Socal. Will personally drive down there to get a tune from him one weekend
===============================================

My current upgrades:
- KW V3 Suspension
- Stage 3 Import Parts Pro (IPP) Custom Built Engine @ 11.0:1 Compression (Currently being built right now) --> Rated up to 850 WHP
- Quaife LSD
- Custom Exhaust with Magnaflow Muffler (Although I do plan to go back and get 3" down pipes later down the road)
- OEM GTR Spark Plugs

Does this sound like a logical order and something that could work? If you guys have suggestions on the order change, please tell me! I would love to hear what you all have to say :)

Any thoughts / opinions / feelings / comments / questions are greatly appreciated by the 370z community. This community is by far the best support I have ever found and have so far that is helping me with my journey to building a fast car :D So thank you everyone!!! =]

The order looks good to go. Just consider that for the first 4 items on the list, re-tuning is needed after each one. So you may want to try and clump some of them together.

This record has still not been broken. Lots of struggling, but no success.
