Hey Guys, Hope everyone's having a great Thanksgiving Weekend!! Lots of our website traffic is from the forum already, really appreciate you all!! -- We have a whole section dedicated to Black Friday Deals, listed here. No special codes required, all pricing is updated already :) Ps. we...

Stock fuel system on 93 with FBO + any drop-in turbo should max out right around 415-420whp. As Corey said, if you have no intentions of upgrading the FS then go for Kuro. Even if you upgrade the FS, 470whp is no slouch and it comes on so strong that anyone who's ridden in the car with me while...

This run is on E35. I'll get some 93 runs in as well. 4th gives a better time for most as it rules out the 3-4 shift delay, but I have seen some Dragy leaderboard runs starting in 3rd, so I'll have to give that a go as well.

Stumbled upon this thread again, sorry I forgot to update! Here's the Dynojet numbers from November 2023, we've been using the same dyno for all our builds. DRob has tuned all of our cars as well on this Dyno. 470/420 on E35 426/393 on 93 25K miles on Kuro 001 now, it's been fantastic! I...

Mileage update on Kuro 001! 25k miles in 3 seasons, 7 track days, 2 trips to Tail of the Dragon, and hundreds of pulls! Here's a recent PB 60-130 so far with a very high DA (Density Altitude) and a run starting in 4th. I will try again with hopefully a much lower DA, and see if 3rd gear is...

I've safely ran 5mm H&R Spacers with Konig wheels in the past, and tracked my Si without any issues. I wouldn't recommend any longer than that for factory studs

Sweet, looking forward to the updates!

Yes, that's normal. It will definitely smoothen out over 500 miles of break-in driving, and the best way to measure an RMM is after a few minutes when the engine heat and movement makes the bushing a tad softer

Thanks Andy! So Nick has tuned many of these in the past, but he's taking a step back to focus on older B and K series, and focus on his Porsche K-swap projects. Nick just rents out the dyno to us and others, so Derek Robinson can remotely tune the cars. We've done it this way for both Si's, my...

It just touched 32lbs for a short instance in the later runs as the IAT's were pretty warm. Under normal driving conditions with these lower temps the ECU is only commanding 27-28lbs W2 BB is fully maxed out here, and Adam's not inclined to push further at this time. We have Shahvan's White Si...

2018 HFP Si Coupe, 90k miles. 2,500 miles on built engine, and 15k miles on 2020 Si trans swap with RV6 Gears. With the shop move and how busy we've been this season we sadly didn't document the process of Adam, my fulfillment guy's HFP Si Coupe build, but we finally hit the dyno after...

Amazing!! Thank You for supporting :) Enjoy the sounds, and in the near future you should definitely consider the 27WON Inlet Pipe, even for aesthetic reasons to get away from the pancaked factory piece :P Humza

Yes, keep aluminum for track wheels only. Other than that it's best to run plastic We have the aluminum version as well just in case https://unity-performance.com/products/aluminum-wheel-hub-centric-ring-set-universal?_pos=2&_psq=73.1&_ss=e&_v=1.0

In 5x114.3 spec the CB is 73.1. We have the 73.1 to 64.1 Rings here. Link to wheels here

I've had Konig, Enkei, and now Superspeed on our Blue Si and Green FK8. Each brand has wheel models that weigh under 20lbs for 18x8.5 and 18x9.5. I've stuck to Superspeed for my last 5 personal sets, especially these RF05RR's that I've had in 18x8.5 +35, 18x9.5 +38 and now in +45. $1,000 for...

Marginal gains without a tune, or even going Catless versus Catted. Best to just save up for both, and install the DP and upload the tune at the same time. We can send out both from our Toronto location to you whenever you're ready :)

Thanks Alex! Hope you're doing well as always :)

Morimoto V2 Headlights! Missed out on saving a set of V1's for ourselves back in the day, so I put aside a set of these right away when we got our first batch. Got them fully ppf'd before install and have been running them for over a month now. Plug n'play application, nothing was modified to...

Couple more updates :) EPR Hood, both for aesthetic and cooling benefits. Got this from a good friend of ours that was parting out his FK8, and I've always loved the style so I couldn't pass up the deal. It came ceramic coated, has a rain-tray, hood pins already installed that we transferred...

Looking forward to the EDFC Active Pro setup on your car! We've had the traditional EDFC on @Thusee Si for a number of years now
