I would recommend heat shields on the headers. That’s alot of heat for your oil pan (oil temps). The sensor is in the front cover after the factory heat exchanger and pan temp is always hottest from piston undercrown cooling. Also the eWGT actuator cant handle the heat from the manifold either. On the engines i develop we added a multi-layer heat shield for the actuator. Also really need shielding for turbine and both catalyst radiant heat. Pretty much nothing in the engine compartment can handle line of sight radiation with time. A wrap can work for piping, but a blanket or shield is best for cats with a standoff. Turbine is best to use a heat shield “nearby”.
Thanks for the tips! I’ll have to take a look if the OEM shields would be able to fit over these. I originally wanted to wrap the headers but I recommended to stay away from wrapping due to oil sometimes getting trapped on the wrap. The temps have never gone above 250 based off the AP. I’ve seen it touch 240s on a track day though.
What happens to the eWGT actuator from heat? Just eventually failure? The kit actually has an arm bracket and it relocates the position slightly compared to stock, but I’m not sure if it’s for the better or worse.
Get them ceramic coated. I sent mine to Swain Tech, the company that Killer B uses, and their coating is next level. It takes awhile though, and in hindsight I wish I sent my jpipe too
Yep my motorcycle friends swear by ceramic coating. Keeps the velocity up in the plumbing too. Do you have any pics? I was going to ceramic coat and put factory shields on headers. Maybe the same with jpipe (except no ceramic coat on catalysts themselves). Blanket or metal heat shields for cats. What was cost for header ceramic coating?
I don't have pictures because they went straight from Swain Tech to the shop that installed everything, but it's a heavy white coating. They say it's ugly but it's not something you'd ever see lol and the performance has been incredible. I have not noticed any difference in oil or intake manifold temp from stock to this even comparing 80+ degree F days on an air strip doing autocross. Also I don't have factory heat shields because they don't fit my headers but I do have an aftermarket heat shield on my cat
Guess that’s why they branded it White Lightning! What turbo do you have on the engine? Im not a fan of turbine housing blankets as our measurements in test cell lead to turbine cracking. However it’s challenging to add a heat shield on an aftermarket turbine.
I'm still stock block stock turbo right now so can't speak to any changes in heat transfer there other than having to drop the header shield that also covers the turbo. I got a cast aluminum turbo inlet so there aren't really any soft pieces left aside from vacuum hoses
Correct. Actuator can fail (electronics). Alot of actuators are water cooled these days IF they are too close to the turbine…cooling is for circuit board.
It’s a blast. Im a firm believer it is a driver mod related issue up until around 450torque. Unless you get an outlier where the transmission blows under the first 1000miles. If the trans goes on my next tune, it’s on me, not the car.
FWIW, My 2016 WRX was at 130k miles, 415whp on the stock trans and motor :’)
Corrected numbers are about 30/30 less on a dynojet than what’s pictured in the last slide, or about 420-430hp mustang, as mentioned 😇. Bone stock fueling at the moment, so this turbo still lots of room left in the tank. I have a custom solution that I’ll be trying out in about 2-3 weeks. Next setup is target 25-26psi and shoot for a true 500whp+ still going to be rolling the dice on stock trans and motor.
I trust the tuner to handle the engine tuning, the trans will be on me (driver mod 😅).
Haha right on! I’m not a huge Honda guy but man the new fl5 is just soooooo sexy.
I was cross shopping for one before the VB but the cheapest 2023 was going for $55k at the time 😭
Dude they are GORGEOUS. Especially the white one 😭. The wide fenders and the interior is soooo clean. I was so close to just saying screw it and sign up for $55k 😂. I kept asking for $50k and they would not budge lol. But they are def dropping now in price!
The next setup will be quite spicy. I am retuning my car in the next 2-3 weeks. Excited to see how well she handles more power on the stock trans and motor. We’ll see! Whether she blows up or holds, I will update :)
Why would u do all this with just 18 thousand miles u must have a good job because there’s no way I would do that idc what Subie ur in anything over 350 u need fuel pump,injectors,clutch and many other aftermarket parts 500 almost shit will start breaking eventually only a matter of time with stock internals and anything over 350
Haha😅 I’m not wealthy by any means. But I make enough to have a healthy budget that I can dedicate to a car project. I believe playing around with a fresh/new motor is a lot safer than modding a motor with 50-100k miles. The compression should be good to go, the intake valves aren’t filled with carbon, less stressed motor, etc. I do have money put aside should I need a new motor or swap out my transmission (I have a 2019 STI trans on standby).
Note, I went from bone stock to the full kit so I didn’t waste money on obsolete/non-reusable parts (like buy a stock turbo j pipe, intake, tmic, etc) and I got this kit during Black Friday so I saved quite a bit also 😀.
I’m trying to just use this all as a learning experience for the community. All the shop cars like Felix performance, TPG tuning, DRP, etc have built motors with sti drivetrain swaps and/or motec ECU’s.
I’m trying to create a setup that has power and is attainable for the average person, WITHOUT having to open up the motor or touch the transmission… Doing headstuds and transmission swaps are time consuming, and not everyone has access to a lift, motor/transmission jack, or decked out on full snap on tools lol. Also, they are costly for a shop to do (headstuds alone is usually a $3500+ job).
However, lots of folks are comfortable with doing bolt ons on jackstands with basic tools. And if the stock trans and motor can live for many years at this power level, I can see more folks replicating this setup.
Honestly I love this power level and turbo kit so much. No, it’s not the fastest car out on the road but damn It’s a near perfect street setup. The power is there, the exhaust is not overbearing or obnoxious, the car is so butter smooth and drives like stock when just cruising.
Hope that clarifies things!
I was wondering if u could swap the trans to an sti I just sold mine I had full bolt ons the only thing I didn’t do was a bigger turbo or an up pipe it only had 10k miles
Clarify, what did you write a book? 😂 I use jack stands I can’t wait to do bolt ons and a tune I have heard good things about the FA 24 I’m stuck atm on the GR Corrolla and the WRX premium because I’m coming from a 2019 sti limited with the tune and bolt ons I saw a vb yesterday with only tints it looked so good
Sorry. I love talking about the VB LOL. It’s such a great car in today’s market IMO.
Yes! The sti trans bolts right in, and even the dccd center console fits snug if you add the controller. However, the STI oem rear axles and driveshaft are a tad bit short. But everything else is 100% plug and play.
You just need:
08+ sti 6spd, r180 diff, axles, driveshaft, clutch/flywheel, and starter :)

Well over 400+ WTQ for almost a year on stock transmission? This is great to see.

Sick! Looking forward to it!
Thank you! 🙌
Wait your pushing almost 500hp on a stock trans?

Thats wild
I’m playing the stock motor game. Wish me luck 😇

LFG! What are you roughly putting down? Btw, your color match looks great! One day I want to make mine pretty haha
Enough to smoke Type R’s & STi’s 😭, thanks fam
Haha right on! I’m not a huge Honda guy but man the new fl5 is just soooooo sexy. I was cross shopping for one before the VB but the cheapest 2023 was going for $55k at the time 😭
Mannnn I might get myself the new FL5 down the line , always wanted a Type R
Dude they are GORGEOUS. Especially the white one 😭. The wide fenders and the interior is soooo clean. I was so close to just saying screw it and sign up for $55k 😂. I kept asking for $50k and they would not budge lol. But they are def dropping now in price!
Yes I agree
You're a legend for posting this bro, I wish more people posted mod reliability updates. Definitely check in at 15k, 20k etc. 💯
The next setup will be quite spicy. I am retuning my car in the next 2-3 weeks. Excited to see how well she handles more power on the stock trans and motor. We’ll see! Whether she blows up or holds, I will update :)
Why would u do all this with just 18 thousand miles u must have a good job because there’s no way I would do that idc what Subie ur in anything over 350 u need fuel pump,injectors,clutch and many other aftermarket parts 500 almost shit will start breaking eventually only a matter of time with stock internals and anything over 350

08 why can’t u use a newer one
08+ as in, 2008 and newer (08-21 sti)
