Toyota Corolla GT-S


This is my low and stiff Corolla for trackdays, autocross, and paved backroads fun. I have put a lot of effort and aftermarket parts into suspension work, and a few bolt-ons for the engine. It is lightweight, responsive, and loves to hassle bigger cars through the twisties! My goal has been to enhance the performance envelope a bit without losing out on driveability or streetability too much. I want light weight and a simple aesthetic with a spectacular overall driving experience and I am pleased with the results so far. Highlights include: -TRD Japan fiberglass hatch and spoiler with lexan window for weight savings -Carbon fiber hood and Japanese bumpers (not pictured) for further weight savings -Lightweight battery for weight savings -Adjustable aluminum suspension arms, heim-jointed one end, hard bushing at the other end for weight savings and handling response without rattling loose any fillings -Homemade short shifter and various body braces -TRD Japan roadrace shocks and springs -Traction brackets to relocate the rear lower control arms and roll center adjusters to relocate the front control arms after lowering -TRD hard bushings wherever there aren’t heim joints -A small dose of negative camber up front and zero toe for great turn-in -Braided brake lines and high performance pads -4-2-1 header, exhaust, Injen intake, and power steering delete to wake the engine up a little bit and further shave the weight -Nardi deep-dish steering wheel for a bit of interior dress-up and a better driving position

How can an AE86 not get more votes? Especially one as nice as this one?

July 17, 2008, 4:45 p.m.

Cool! (Check mine out haha) Where'd you get the 4-2-1 header? Update the pic with the new bumpers too

Aug. 27, 2008, 5:11 p.m.

I got the header from a company called KBD, and sadly they are now discontinued. I think at one point they were known as Dobi, and made the headers back when the car was fairly new. These days they do mostly bodykits, but several years ago we got a couple dozen Corolla owners together and had them do one last run. Apparently they got rid of the tooling after that last batch. :( It is a nice street header because it enhances and smooths all of the powerband over stock, and saves a nice bit of weight. Unlike most of the other offerings on the market, it is designed first and foremost for LHD cars, so it fits, and the primaries are a good size for a stock head with other breathing upgrades (mild tune.) Most others on the market are good for heavier mods or racecars, but give up some bottom/mid range on the street. I will have to take some pics when I get the bumper back on. I took it off again to tidy up wiring for the lights and so my buddy could copy the Japanese bumper brackets.

Man, beautiful ride. Great to read @ your engine builkd up. My 4age is going together much milder-webbers, stock cams, timing pulleys, on a 120K engine. Good to get ideas for that inevitable first rebuild.

Dec. 6, 2009, 10:34 a.m.

NICE car! I've always wanted one, even before the drift craze hit, I'm gonna have to keep an eye out for one after new years, gotta finish my rx7 first. Again, NICE!

Dec. 18, 2009, 12:29 a.m.

Thanks for the comments, guys! I am always flattered when someone else finds my efforts inspirational. I am getting excited to drop the engine in and get it wired and fired this winter in anticipation of driving it next spring and summer. My buddy I've been helping is nearing completion on his similar build right now, so we should be able to focus on my car soon; keep your eyes peeled for updates!

Awesome HachiRoku!

June 10, 2010, 11:28 a.m.

Wow awesome Hatchi dude! The engine work is super clean! The wheels are xxr 513 in gunmetal =] they look great on corollas!

I like the red wrinkle paint on the valve covers. Those aluminum pulleys (free horsepower) look good too. Reminds me of rebuilding my 4AGE on lunch breaks at my job. Good times. What kind of cams are you using?

Dec. 22, 2011, 9:23 p.m.

Thanks guys...sorry I have been so-so about updates. The camshafts are older HKS 272's (both intake and exhaust.) They are 272 degrees advertised duration with 8.35mm of lift. I was going to use HKS 288's with 8.35mm of lift, but the bottom end wasn't built for enough revs (or at least not reliably) to get the most of the 288's, so I downsized, and I think I will be happy with a big midrange-top end power boost. I am planning on an 8300rpm rev-limiter.
