Topgunz - air to air upgrade

JWillis72

Did you dyno this weekend?

BOLIO 671

Hey Evohunter.... Are u on TopGunZ kit or the tabricated prototype from Boosted Performance? So far u seem to be the only person I know that's on the standard Stillen kit Pump and Injectors....Feeling things out to see how ur travels go as I have no need to upgrade my fuel system due to having limited rated octane of 91 @ the pump with no likely future of Ethanol or E85 fuels....

I'm running ID1300, 340lph pump, and the S1 fuel return with the A2A conversion. It's probably better to be safe than sorry if you intend on doing the conversion. E85 also needs 30% more fuel, so you'll have to upgrade eventually.

TopgunZ

I should start writing things down. Do you have the SI upgraded trim?

Nope. SCI V3, 9psi pulley (2.75"), and K&N filter. Starting with 93 pump fuel and moving onto E85 once they start producing the new S1 fuel return kit.

Cool this is what I'm looking for, as I'll be the same to start with then upgrade to E85 later most likely, are you going to be using the same dyno for comparison?

milkcow500

Yes I will be.

In your MyG37 thread, it said you still did have problems making this a2a kit fit and custom fabricating was indeed needed.

Also, what's the holdup on the S1 fuel return kit? I'm the other G37 coupe trying to get all of this done right the first time.

Luckily there is an e85 pump near my house, so that's a plus, but, realistically, what am I to gain from e85 over 93 pump?

I will be getting the V3 with 9lb pulley, ID100, and 340lph. Just want to make sure the extra needed for e85 is worth it...

TopgunZ

Now that we have a way to keep the temps cool and reliability to the stillen kit has skyrocketed, the Si trim will really take advantage of this kit. I wouldn't recommend the 9psi pulley with the Si trim on the water cooled system but this A2A kit is just begging for it.

Sent you a PM about pricing/shipping to me etc..

TopgunZ

I talked to him about this last night. He sent me some pics of how they cut into the y pipe where it fits up to the intercooler and they already had it cut and rewelded to accommodate the fact they had the brackets on wrong prior to putting the brackets on right.

SO.... We still do not know 100% if the kit will fit perfectly up with a G. However, I really think it will.

there shouldn't be anything different, the install instructions are the same.

the only thing that is different is the front rad support, you might need to cut more away, but otherwise there shouldn't be any issues.

The g37 engine bay does seem a little bit narrower, but we know they use the same intake pipe from stillen kit on the g37/370z

Yeah there's no 100% way of what happened unfortunately. Here's how it went down.

1. Installed FMIC brackets upside-down.
2. Shop decided to cut/weld an extension on the bottom of the Y-pipe to get it to fit.
3. Informed the shop that the FMIC brackets are upside-down.
4. Shop flipped ONLY the passenger side bracket - Not sure if they really did anything (Doesn't really matter at this point because the Y-pipe was altered).
5. One pipe now won't align with the throttle body.
6. Welded an extension on that pipe in order to fit.

My shop works on a LOT of 370z's and they told me that the G37 has less room in the front. Not sure if this is true, but we won't really know until the next guy tries. I went to the shop and took a look at the front and I really don't see a crazy difference, then again I'm no expert. I honestly feel like it will fit with either much less fabrication or without any at all.

I intend on going E85 next month. I highly suggest it as it makes a world of difference in terms of power.

Hey Topz.... Are your kits in yet? I'm just waiting on EVOHUNTERS results as I am on the stock Stillen Pump and Injectors with a 9lb pulley...If the Stillen fuel set up won't work I will have to factor upgrading the fuel system which isn't a big priority for me since on Guam they only sale 91 at the pump. I have no access to E85 and honestly dont think that will ever be an option here. I have a tune for race fuel but I only pour that into the tank when I'm gonna hit the track.....other than that she's always drinking 91.

If you running the stock pulley setup on your blower youll be fine.

Im a running a 2.75 on blower instead of 3.20", We arnt even sure what kind of boost we will see with it yet.
