Corolla Intake Manifold

[benjie]

So as not to post jack anymore of steed's post, I am creating a new post.

Regarding using the manifold from a bug eyed corolla, can that run on a stock car or would I require aftermarket electronics to make it happy? I have a 94 paseo 5efe and I'm not looking to turbo. I just want to get every drop i can get out of his car.

Its just a simple swap buddy.

this is the back of the kind of corolla you are looking for over in the US:

any noticeable gains? throttle response etc?

[Galliano]

Throttle is slightly more responsive and it does pick up quicker off the mark due to more air flow.

As aforementioned more airflow, it means more fuel, I find I cannot get the estimated MPG from the Paseo and my theory is due to the more air = more fuel mix.. Must be that. Though, I did get 404 miles from a full tank whereas standard they get around 430-450 miles to a tank.

[steed]

you can actually get more miles on that mani if driven sensibly, i think it's to do with harmonics or something clever like that where, because of the longer matched runners, the air actually scavenges itself. so at about 3000 rpm you don't have drive too hard to get good torque delivery.

oh and noticeable gains, the most prominent one is the is loads (i mean lots and lots) more torque low down the rev range.

Problem is, my exhaust is BAWWWW so I give it BAWWWW's ...

Though when I am heading towards empty and I have no money I drive quietly.

You aren't really taking in any more air than the standard manifold, what you're doing is altering the flow characteristics, (or "harmonics" as already mentioned).

The same as with a 4-1 exhaust manifold for example, you aren't getting rid of any extra exhaust gas, you're just freeing the restriction that comes with the standard manifold, which gives you power gains in certain areas of the rev range (usually up top for a good 4-1).

i know the feeling. the ITB's are much of a 'BAWWWWWW' ness and does drink fuel because of this condition.

[Ross Martyn]

sorry did you say 430-450! mate, i'm pretty sure my best was 350 and that likes all motorways, when I was driving to so'ton and back every day, traffic etc, id get about 250.

either I have some engine issues, or just a case of the lead foot...

[Galliano]

I'm pretty sure Mikey Jay got some awesome fuel consumption in his first Paseo, somewhere around that mark..?

[Ross Martyn]

any ideas why? perhaps needs a good service, also has the epic oil usage I fear. starting to worry about this thing!

[Galliano]

Didn't you say its got like 80-90k? I've not seen many Paseos past 100k that don't burn oil. Give it a service, no harm in that, and drive like a saint, you will have fuel consumptions winning you!

[Ross Martyn]

yeah its at 96k. I shall give it a go when I get some cash!

[Galliano]

All cars act differently. It also depends on individual driving style and how the cars been treated in the past. If its had a hard life things will go wrong, if its well looked after and kept up to date on belts, filters, levels etc it will perform alot better.

i only get around 250 miles to a tank aswell....

just had new belts, plugs, leads and and a bloody good service.

ah well..its fun to drive
