Vargas Turbo journey and review/results

[WhoStoleMyVTEC]

As for the HPFP, my situation is different from you guys with the Si. The HPFP base is different between Si and Base 1.5t which makes the HPFP sit at a different angle slightly. I modified the hardline to account for the change in angle and played with different fuel feed fittings, but at the end of the day my OE base HPFP worked out best for me. I was using an e-tuner in Brazil for CVTs and a lot of it was trial and error. For the Si's, from what I've learned you'll just swap over the hardline and fuel feed fitting to the Accord HPFP.

As for the injector PnP harness, you use the male plugs from the 9th Gen Si. They look slightly different from ours upon closer inspection but it works perfectly and is the only option I found. I had to buy PnP harnesses made for 9th Gen Si and just cut the male plugs off. The Accord 2.0t side uses a female Denso bottom slot plug. Denso makes a few versions and the bottom slot is less common. I bought some from ebay and found a cheaper alternative on Aliexpress too.

Hope that helps, I had a hell of a time trying to figure this all out. You can literally piece the same fuel kits being sold for 1/2 the price.

This is golden. Thanks for spreading the info. Time to get to work!

And the one we need to connect to our harness is…

I’ll order a few and make some

Nice work! This Vargas thread turned into a nice lil DIY session lol. Thanks for sharing the part numbers and all your other input. Narrowed this one down nicely

Just recieved the terminals. Now I can make. Love this stuff.

I have a si, how should I go about my flex fuel line not plugging into the accord HPFP?

Nice work! I am going to put my GC+ in this weekend with 27WON TIP and then I will be getting the rest of the stuff ready to do this fuel system.

Harnesses look great

Some more injector fun.

I know Hondata has verified that the 2.0T HPFP internally isn't any different than the Si HPFP. I'm wondering if just swapping out the 2.0T injectors with the appropriate conversion pigtails + a LPFP upgrade + a drilled high pressure hardline would be a sufficient upgrade. Or is there some kind of magic in the 2.0T HPFP?

There are threads on this matter.
They are not the same pumps. But take a look and decide on your own.

Opened the cams up for some photos, not sure what you can make of them but they are definitely high quality.

Any update on what happened with these?

Sorry everyone I've been pretty busy and not checking in. As of right now I have a track event in August, but afterwards Cams, TSP block, Fueling and some other small goodies I have will be going in. I may even just switch up to the GC+ while I am at it but undecided.

The gc+ is a monster on the track... I tested it 2 times of 2 session of 15mins it's a beast ... you have the full power 4k to redline and you don't see turbo lag with the ball bearing. I did my first oil change like 3 weeks ago and the amsoil 0w-40 signature its the perfect oil ... when I droped it... 0 smell of gas from the oil and did all the winter with it... droped at like 30-40%... I feel the amsoil is way better to protect ur motor and turbo. I'm waiting on some few parts to complete my final build and be ready for the track intercooler, bbk, new lower ball joint and new front grill like the procivic. Only missing my caliper and grill.

I'm on the ots tune and the knock is not moving lol 0.49 all day map 3 maybe I saw like 3 times of 20 sec moved to 0.51.
One 15 min session my knock was solid to at 0.49

I also droped my trans oil and changed to amsoil syncromesh ... it's way better then oem. 1 times changed to oem and 1 time to syncromesh.

I will make a post in the si forum when all will be done like at the end of april. I will start doing some lapping maybe mid may.

Good stuff.

The biggest reason i'm considering the change from GC to the GC+ is to make the most out of the cams/fueling upgrades. Even though my dyno sessions with the GC were limited by fueling there is no telling how much more you can get out of it

On vargas they said good for 400 whp + with the gc+. For my taste the map 3 on the ots its like 315 whp 315 torque and I don't realy need more then this for my little track it's a 1.18 min per lap. Pulling 1 time the 4th gear.
