Engine obx forza header

I've seen that come more into play when someone chooses a cam with too much overlap. Couple that with a virtually open aftermarket exhaust and the subsequent signal to lean out that the O2 will start sending and you'll likely find yourself with a burnt valve or two.

those jp header is used mainly with the supercharger.

is the firing order for the 8th gen still 1-4-3-2 ? i think the first two headers keep a rotational flow if the 1st cylinder is the one all the way to the right or closest to serp belt

Its 1-3-4-2

The header runners are equilength it seems. Doesn't that help with exhaust scavenging?

I've noticed my motor sounds a lot different when it's idling now. It has a rumble and you can actually count the beats in the exhaust cycle. Before, it was all jumbled.

mine has a rumble when i have the AC unit on.

sometimes my exhaust seems to be pulsating, not sure if that's a good or bad thing.

Links?

WARNING: This is for everyone who is planning on getting the Forza header. It is NOT bolt on. It requires modification to fit properly. The header requires that a small section of the cojoining header to exhaust area be removed before it can sit correctly. Otherwise, the exhaust gasket O ring will not seal correctly and will result in a nasty exhaust leak. Even after removing the section of header and fitting correctly, the O ring gasket still might not seal correctly. This can result in the already mentioned exhaust leak and maybe an annoying rattle from the vibration. The header is a one piece without a flex tube so it vibrates against the exhaust section. I solved all these problems by bringing it to my local exhaust shop to get welded permanently to the exhaust section. Good luck everyone.

thanks rollatuner110 for the heads up

yeah i was expecting to have this welded on

No problem. I just want to keep the awareness up to date. Welding for me was 20 bucks btw.

thx bro, do you have any pics of your FORZA Header on your Corolla??
