1986 Toyota Corolla SR5 cam and header

My 1986 Toyota Corolla SR5 with a 4AC under the hood. I've installed a Schneider 300F camshaft, double valve springs, MSD 6AL ignition system, and custom made header and exhaust.

@forrestmagel - The exhaust system on the car in this video was totally illegally loud. It was a custom made 4AC header, downpipe, 3" diameter 24" long Cherry Bomb glasspack, and a 45° bend out to tips.

@Lkjbl - No. I bought it pre-made. In addition, I don't own the car anymore, otherwise I'd measure and send you some details. Here's a picture of it off the car, though.

@ MrLione123 - I loved this car. Definitely had a CD with Initial D soundtrack music on it for this reason.

@quinngetsitdaily - Two things - first, there's minimal difference between the bottom end of a 4AGE and 4AC. The 4AGE revs to 7000+ stock. Second, if it did break, I was going to replace the bottom end with either a 7AFE bottom end to make a 7AC, or replace the bottom end with one of many nearly free 4ACs available from the local Toyota enthusiast community.

It runs damn amazing! Great work!

@TheHald - Thanks! After the work, I had it dyno tuned at a local shop. They were able to use a wideband O2 sensor to get the mixture dead on. It was a lot of fun after that. I sold this car in January (2011), so I don't have it anymore. The stock 4AC intake doesn't flow well enough to bother with more or a bigger carb. You'd have to make a custom manifold, or get side drafts to make it worth while. Thanks for the interest!

what exhaust muffler where you using

[danielsong25]

This kinda shows the limit of single cam SR5.. I mean SR5 is great and some plp can't afford GT-S but I kinda think it's a waste of factory making these instead of using the factory to make classic GT-S. Just an opinion.. Still, nice car

[Lkjbl]

have any plans or detailed sketches to make a 4ac header

[MrLione123]

Feel like Takumi :)

Que bien suena!!!, que envidia!!... pero... 8000 rpm en un 4AC???, en teoria solo aguanta hasta 6000 ¿no?, tambien "rebajaste el volante"??(light flywheel)???, me gustaria saber con mas detalles que le hiciste por favoorr!!. Gracias!!

NICE MAN ! The header made a WORLD of difference ! Compared to your last vid I can see the rpm's climbing at a much faster rate. :)
