You're consistent process of elimination and engineering is why I watch every one of your videos. I'm the guy that takes aftermarket parts and modifies them to make them better and it seems as a standard you do the same. I would also really like to purchase a throttle body spacer for a K20 Z3!
I absolutely LOVE that exhaust you guys built for this Ep3! I actually own an Ep3 that I’d really like that same exhaust for. Maybe I could bring you guys my car sometime. Fortunately enough I live about an hour and a half away!
Rdx injectors will solve that, I ran 96% at 8400rpm w/ cycle duty at 12.7 -13.0 AFR on stockers on my FBO 8th gen si.. After OEM rdx injectors im down to around 75% and picked up some decent power. Awesome videos Guys!
I agree, RDX injectors are the best budget injector I've used on hondas. That screen they removed changed spray pattern, not in a good way. With the RDX they get flow and honda optimized spray pattern.
Love the content guys. Wow I can't believe how clean that ep3 engine bay is. Love the exhaust also. Looking foward to seeing more of George's Mugen too that thing is sweet. Keep up the great work guys.
@@LHTPerformance Hey John, any chance you are gonna make more spacers for the 8th gen? I missed the opportunity. I would love to have at least something from LHT lol. I also heard a rumor that you used to make intercoolers/aftercoolers? Just wanted to know if that was just a rumor or not.
Rbc...Rbc...Rbc...Thanks for solving an age old question for a k20 vs k24.. I have a suggestion... Buy an RBC put a j37 Throttle body on and dyno it.. If its possible go even one step further and get the jdm k20 intake cam..(one for george too) put oem k20 valvesprings on the k24.. Rev it to 8500 Thats as much power the k24 would make on a budget and not touching the head..and yeah when u change the cam change the cam gear to 50° from the 25° stock.. Also do a j37 throttle on george's k20 and than we have most stock tuned honda k20 vs k24.. Keep up the good work..love the new content and its good when you are waiting for a new video..that means you are doing something right. How copy-paste are k20 vs k24 dyno's now..just 25hp more
stefce trajkovski the k24 can’t rev that high without a type s oil pump, after 76-7800 rpm it loses oil pressure and is not healthy for the motor, you’ll eat the bearings, get a type s oil pump or a 4 piston type s ported oil pump and you can rev the k24 to the moon.
Never knew u could take those caps off to make them flow more🤔 good. great tip u blew my mind there 🤯. Great video keep up the great work. I'm glad u posted part2 on the EP3 so fast.
This is awsome.i have a k24a2 05 tsx motor with full acura type s internals im a k series dude with a 100 shit dry and i love this channel i learned alot from dyno pulls lol keep on teacher 😁 made 260 on e85
I can agree with doing the rbc on the k24. Before i did the rbc swap my torque dropped like that but after the rbc it held wayyyy better up top and by redline i was making 10wtq more compared to my stock manifold because of how much better torque was holding
Even a universal weld on twin loop would be nice . They could sell them, even do titanium option. Prolly gonna be a $200-400 muffler but it'll be worth it. If they ever offer it
Nice job.. do you make an x-pipe for a C7 ZO6. I want to get rid of those rear cats... I watched your vlog and borla dont make the full x-pipe anymore.. thanks
Hmm you should recheck your tune... My k20a2 , 70mm rbc, 70mm sk2 throttle body, custom 421 header, custom 3" exhaust, doctronic ecu, and makes 241 whp
I made one,up sized my header exit to 3inch all the way to resonator and muffler..i run my oem fg2 reso and muffler...no rasp,sounds allmost stock under 4k rpms... When u go wot the intake sounds more then the exhaust its awesome..had to add 12% fuel so it makes tons of power..had to use rdx injectors because i was at 98% duty cycle..where i live exhaust mods gets your car towed away so im good..catless
Aret Zelli We actually did a back to back and the spray pattern still looks good with the screen off. I heard most of the 1000cc injectors are de capped 550cc.

Nice episode
I think the twin loop muffler is robbing a bit of power though
ZunoFG4 You put some
Money on it ? We’ll do a live video and do a back to back run. 😋
LHTPerformance test it vs a 3” vibrant straight through muffler
ZunoFG4 This is straight through. I’d drop the axle back so there’s no guessing.
Can you mass produce the twin loop muffler for rsx’?
Even a universal weld on twin loop would be nice . They could sell them, even do titanium option. Prolly gonna be a $200-400 muffler but it'll be worth it. If they ever offer it
They don't mass produce anything. If you want something done, gotta take your car to them. One day I plan on taking my Yaris there for a system.
There’s a twin loop on eBay that’s a Mugen rep.
Big D Slap yeah obx but does it eliminate the drone at all?
k00lball3r Check our the titanium exhaust we built for for the Integra
I find it odd that you had such an issue with the stock injectors. I don't think it went above 75% duty to make 217whp on my K24a2 build.
Nice job.. do you make an x-pipe for a C7 ZO6. I want to get rid of those rear cats... I watched your vlog and borla dont make the full x-pipe anymore.. thanks
Any significant gains bore ing out the throttle body? Loving the series everything is fantastic brother.
Camlobes Vtec on the k series not a lot from what I’ve seen, the older series motors can get some crazy gains from porting the throttle body runners
Cool thinking about porting an extra stock intake manifold that I have.
Sounds so good.
You should try a blox racing velocity stack and dry flow filter with the throttle body spacer
sounds so good!
Mt friend made 220 stock 24a2 from a jdm odyssey on a 06 civic si (si intake, injectors and cold air intake, stock exhaust)
Ok, and?
This makes me want an ep3 again
They're neat cars. Driven a few though work.. that shifter though 😁
I definitely think the lht spacer would improve the stock manifold and gain 7+HP
My K20A with an RBC ported n polished, 70mm TB and full custom 3" exhaust and custom header made 219whp and 160tq

I want to move to Florida. I have many professional years in automotive. Are you hiring?
RDX injectors 410cc .. i have them in my FN2 R
Can't you get those kind of gains from just bigger injectors and a tune alone? I can't 100% agree a 3" exhaust itself provides the additional HP
Ted Taylor We did some dynos showing this. Stock exhaust is made 180 ish. Open header made 205.....
What muffler and resonator did you use? Please more details.
Doesn't the screen help even the spray for better performance?
Aret Zelli We actually did a back to back and the spray pattern still looks good with the screen off. I heard most of the 1000cc injectors are de capped 550cc.
Sounds like stock FN2 exhaust with more intake noise.
Can we get a clip of how it sounds like from the inside? I want to hear how loud it is in the cabin please.
Hwoah We May do a follow up video and include that.
Massive gains up top and massive losses down low,maybe even that out ???
You might be reading the sheet wrong. There was no losses. Look at 10:07 for the before and after
If that’s before and after on the same chart everything under 5200 rpm was a loss with no gains until about 5300 rpm
@@Everydayprojects365 Are you looking the AF ratio line ? If you look at the HP and Tq you’ll clearly see it makes more power everywhere. The red shows more increase the whole graph.
