Project S-21: HKS Single Hi-Power Install

Last thursday Otto and I started working on the installation of this aftermarket exhaust (catback). Okay it was basically him..



I bought this used exhaust from girls2k. Also I bought a gasket from AutoZone and a brand new lower tie bar from Honda OEM parts.

We had the parts and tools, but the installation was not easy!

First of all taking off the old rear lower tie bar was not that simple. Bolts and nuts were rusted and it was bent. Secondly the pipe was stuck at the cat end.. Moreover the gasket I bought didn't fit on both sides (the pipe and the cat).

So... we went to local AutoZone and Advance Auto Parts for another gasket which might be a fit. Well not a single one turned out to be a good one.. What we did was discovering the inventory of gaskets at Advance Auto Parts. We ended up with a most possible one and Otto did the customization based on it. Used drilling tool to add a new hole and in addition to that he cut more around the other two holes to make it fit on the cat side.. The time cost for this single step was more than an hour..

The rest of the work was much easier. But with OEM ap1 hangers the middle pipe was going to hit the lower tie bar. So adjusting the first hanger out there is a must for HKS Hi-Power Single Exhaust.

The exhaust size is 75mm.

We started at around 4:30pm and finished at 10pm...


The sound of HKS is awesome. However, a lot of drone is produced. Really a lot. But I do love the higher volumn of the exhaust.

S2000 Torque Specs (from S2KI)

Torque specs S2000 AP1 Torque Specs for various bolts (in alpha order) These were all taken from a Shop Manual... they are all listed in lbf-ft and if says + xx* then tighten to the initial torque spec and tighten another xx degrees. Dont forget to tighten some bolts in an inside out pattern and multiple stages (such as head bolts, oil pan bolts, or lower block bolts just to name a few). This is not a complete list, but as much as I could handle.

Cornering: cornering force vs slip angle

Image
Everyone says that the best way to improve your car's handling, the best mod to do at the very beginning is and always is the tire. Good tires stand for excellent handling and bad tires mean terrible cornering. What is the story of tires and cornering? Cornering force vs slip angle In general when a car goes through a corner, there is a centrifugal force out there, and you could feel being thrown towards the outside. In order to successfully drive out the corner, the car would need some lateral force to help support the car push against that centrifugal force. That is the so called cornering force. Due to the cornering force as well as the acceleration force on the tire parallel to the tire direction, the force would be directed towards some angle from the tires' direction (assume that ideally all the tires have the same properties, which point to only one direction). The angle is the slip angle. You can notice obvious slip angles in any racing event when race cars mak

Project S-18: RSG Gears Lip installation

Image
Finally I decided to get my lip installed. I tried to install it myself, but when I put it on it had bad fitment. Adhesive and other tricks needed. After calling Rockstar Garage, I took it to K2 Auto Body for the installation. They said they heated the bumper up to like 150 degrees, flexing both the bumper and the lip. However, it was still pretty hard to fit onto the bumper without some trimming. Since the lip was already painted by RSG, they ended up using some adhesive (like plastic) to hang it on the bumper. Both sides and middle section were applied with this adhesive and held firm there. Also they put two bolts on the bottom tabs on the lip, to the bottom of the bumper.  There is still like 1/4 of a inch gap besides the middle section. It's kinda inevitable though. Here's what the car looks like after the installation: Looks nice so I am good with this hack :) 3/6/17
