    Advice on Induction & Exhaust components

    If you are using a stock exhaust manifold and just running without catalytic converter. Most likely your AFR aren't in harms way. The stock ECU could still make corrections for that. With stock intake manifold and stock exhaust manifold you are still getting about the same vacuum and airflow...

    This .pdf has data will further add on to the same findings from Kelvin. Shouldn't be much difference between RSX and Integra Type R. The SAI and scrub radius are going to be tad different because the Integra Type R control arm is longer and hub also is longer.

    If you have to ask where to get damper rod and piston. Then automatically you should go to Tein. We don't even know if that's a twin tube or a monotube. Judging by thickness and length i'm guessing twin tube. Not only that do you know how much oil to use vs the pressure tuning they used with...

    Who runs a oil cooler on a dc5?

    Haven't seen them fail. And it wouldn't really wouldn't mess up the engine. If it leaks you should see engine get hot. Also if you do anything other than daily driving. Like track; I would get oil pressure gauge. I've been through 3 engines.

    The fastest DC5 in Japan!

    Definitely an inspiration for my own car. I've been following their build for awhile. They have huge spring rates. I'm guessing to handle the downforce, tires, and no longer needing sways.

    From what I looked, I might go with them after i'm done with my Yellow Speed's https://www.ycwsuspension.com/shop/dampers-parts/coilover-kits/testers-required/

    Yeah I was thinking you were using the intake that goes back towards the header in order to get those high temperatures. I have a custom intake made by a parts designer for Kseries. Then it gets fed air from outside from the fog light hole. As long car is moving it will stay 10 C or less within...

    Ok good, well that rules out leaking. Be sure to get those things installed. Oil Pressure Gauge is totally worth it if you are going to track often. Hopefully your intake only gets to 60 C after sitting still for awhile. Because if its reaching those temps while moving. Thats bad too. It should...

    Tbh, I would stick with 5w-40 or 10w-40(Your hottest days) if you are using OEM rods with OEM bearing clearances. If anything I would go full synthetic so it has additives that will help resist breakdown. Here in Texas(United States) as one of the hotter states we get up to 40+C in our deep...

    They all do, that's why I use this baffle to prevent it from happening instead of a full pan baffle. Blocks oil from sloshing into the chain case. And has trap doors to let any oil behind it drip back down into the oil pan. Then I installed this line into the port for oil pressure switch that...

    Power drop

    As the oil gets hotter it breaks down more thus the oil pressure is less. When oil sloshes up into the chain case it has to have a chance to fall back down into the sump so the pump can pump it through. Turn after Turn you are putting more oil up into that case. Then on your cool down lap I...

    Well I noticed he said this " On Thursday I noticed something else, VTEC went on/off when accelerating out of corners around 6000rpm. " I've lost three engines total due to leaks and just oil issues. My rod bearings were basically on there way out and the car accelerated slow enough that a...

    Sounds like you are losing oil pressure. What oil are you using? Do you have an oil baffle?

    Wow! Excellent information. Thank you sir.

    Well the only info I have is stock the SAI is 18degrees. But depending on your wheel offset, tire sidewall, LCA(which most of us are using Type-R control arm) and how much you moved your strut... Will determine your scrub radius. So no telling without getting down there and measuring it yourself. ;)

    You want steering arm pivot to Instant center. Roll center is where the Moment arm between center of gravity of the car and the Intersection of the imaginary arm that goes from the tires contact patch center to Instant Center. If they have different swing arcs this causes a Toe out/In as they...

    Cool youtube channel you have. Hello, As Sam said with you need to concern with Instant Center. Instant Center is where the Upper control arm intersects the lower control arm. On the DC5 the upper control arm would be the top nut of the strut tower. When you lower our car you will notice that...

    PCI stated that stock the DC5 has the same amount of bumpsteer typical of any stock car. But as Sam stated. Honda did create the DC5 with a very limited window. The closer to stock the better the geometry flows together. So the cool part is figuring out how to maintain that while getting more...

    I have two videos going over my research into Torque steer and Bump steer with this chassis. So i've found that in order to satisfy proper geometry for minimal bump steer. That the coilovers should have an arm similar to the OEM strut. And that the Tie Rod end should connect from the top...
